Description
本發明係關於在許多自行車上可發現之一種變速齒輪系統，特別關於一種齒輪系統，其傳動體上之複合槽鍵中具有硬***件。This invention relates to a shifting gear system that can be found on many bicycles, and more particularly to a gear system having a hard insert in the compound slot key on the transmission.
在自行車上，後自行車輪轂與帶槽鍵之傳動體(splined drive bodies)相配合，以支撐變速驅動齒輪(multiple drive sprockets)。回顧1970年代，在傳動體上有5檔變速齒輪是相當常見。這些驅動齒輪和裝設在曲軸(crank)上之兩鏈輪(sprockets)或鏈環(chain rings)，提供騎士們可利用之10種不同齒輪比(gear ratios)或變速比。然而，近年來，為增加自行車騎士更多的變速選擇，在後自行車輪轂中之傳動體上之驅動齒輪數目也隨之增加，而為在有限空間內容納增加之齒輪，齒輪的厚度隨之而減少。高性能的自行車設計者努力將自行車的重量減輕，因為一般而言，自行車的性能與重量係呈反比關係。當重量降低，性能比(performance ratio)通常是提升的。承載齒輪之帶槽鍵之傳動體通常是以相當硬的材質製作，例如鋼材。然而，許多高性能自行車輪轂包括帶槽鍵之傳動體是以較軟的材料製作，例如鋁合金。On bicycles, the rear bicycle hub cooperates with splined drive bodies to support multiple drive sprockets. Looking back at the 1970s, it was quite common to have a 5-speed gear on the transmission. These drive gears and the two sprockets or chain rings mounted on the crank provide 10 different gear ratios or gear ratios available to the riders. However, in recent years, in order to increase the bicycle's more shifting options, the number of driving gears on the transmission body in the rear bicycle hub has also increased, and the gear thickness has increased in order to accommodate the increased gear in the limited space. cut back. High-performance bicycle designers strive to reduce the weight of bicycles because, in general, the performance of bicycles is inversely related to the weight. When the weight is reduced, the performance ratio is usually improved. The drive of the slotted key carrying the gear is usually made of a relatively hard material, such as steel. However, many high performance bicycle hubs including slotted transmissions are made of a relatively soft material, such as an aluminum alloy.
一變速自行車之一後輪轂(real hub)RH顯示在圖1中，而且其一般包括複數個齒輪(sprockets)S，齒輪S是設置在外部帶槽鍵之傳動體DB上。齒輪S(圖1和1A所示)是在內部以 互補的方式形成齒槽(spline)結構，所以由鏈條(chain；未繪示)傳遞至齒輪S之轉矩(torque)依次傳遞至和經過傳動體DB、如一般所知之方式傳遞至輪轂凸緣(hub flange)HF，以及與後輪轂RH相連之後輪。傳統的變速系統(未繪示)用於將鏈條移動至或離開不同的齒輪S，藉此提供騎士選擇和使用不同的變速比。傳動體DB具筒形狀，其上提供有複數根槽鍵DBS，槽鍵DBS在傳動體DB的外表面，沿徑向上短距離延伸。在槽鍵DBS之間，有相應之凹槽G。槽鍵DBS與凹槽G在軸向上，以接近傳動體DB之寬度之距離延伸。各齒輪S(圖1A)之中央處有一安裝孔(mounting hole)，在安裝孔內設有齒輪孔齒槽(sprocket hole splines)SHS，齒輪孔齒槽SHS與傳動體槽鍵DBS係相互配合(complement)。在此結構下，傳遞至齒輪S之轉矩(從鏈條或類似者；未繪示)依次傳遞至在後輪轂RH中之傳動體DB。各傳動體槽鍵DBS有一力接收面FRF(圖1)，其與齒輪孔齒槽SHS之力傳遞面FTF(圖1A)協作，如此傳遞至齒輪S之轉矩可被傳往傳動體DB。A real hub RH of one of the variable speed bicycles is shown in Fig. 1, and generally includes a plurality of sprockets S which are disposed on the externally coupled drive shaft DB. Gear S (shown in Figures 1 and 1A) is internally The complementary manner forms a spline structure, so the torque transmitted by the chain (not shown) to the gear S is transmitted to and through the transmission DB, as is generally known, to the hub projection. Hub flange HF, and the rear wheel connected to the rear hub RH. Conventional shifting systems (not shown) are used to move the chain to or from the different gears S, thereby providing the knight to select and use different gear ratios. The transmission body DB has a cylindrical shape, and a plurality of groove keys DBS are provided thereon, and the groove key DBS extends on the outer surface of the transmission body DB in a short distance in the radial direction. Between the slot keys DBS, there is a corresponding groove G. The groove key DBS and the groove G extend in the axial direction at a distance close to the width of the transmission body DB. There is a mounting hole at the center of each gear S (Fig. 1A), and a sprocket hole splines SHS is arranged in the mounting hole, and the gear hole slot SHS and the transmission slot key DBS cooperate with each other ( Complement). Under this configuration, the torque transmitted to the gear S (from a chain or the like; not shown) is sequentially transmitted to the transmission body DB in the rear hub RH. Each of the transmission slot keys DBS has a force receiving surface FRF (Fig. 1) which cooperates with the force transmission surface FTF (Fig. 1A) of the gear slot cogging SHS, so that the torque transmitted to the gear S can be transmitted to the transmission DB.
齒輪S之力傳遞面FTF之面積小，而此會造成非常高之負荷(loads)傳遞到小部分之傳動體槽鍵DBS之力接收面FRF上。以鋼材製作之傳動體DB一般可承受這些高負荷。然而，在裝配鋼齒輪之高性能輪轂，和以鋁合金或其他更輕但較軟的材料製作之輕量化傳動體中，齒輪S之力傳遞面FTF可能和確實會損壞槽鍵DBS之力接收面FRF。這將會造成磨損，且最後齒輪和傳動體在轉動時不再密合的情形下 ，產生加速磨損。近幾年來，齒輪S之厚度降低，以在傳動體上容納更多的齒輪。此發展趨勢之結果是，更大的負荷從齒輪孔齒槽SHS之力傳遞面FTF傳遞至更小部分之傳動體槽鍵DBS之力接收面FRF上。The area of the force transmitting surface FTF of the gear S is small, and this causes a very high load to be transmitted to the small force receiving surface FRF of the transmission slot key DBS. The transmission DB made of steel can generally withstand these high loads. However, in high-performance wheels with steel gears and lightweight transmissions made of aluminum or other lighter but softer materials, the force transfer surface FTF of the gear S may and will damage the slot key DBS. Face FRF. This will cause wear and tear, and finally the gear and the transmission body will no longer fit when rotating. , resulting in accelerated wear. In recent years, the thickness of the gear S has been reduced to accommodate more gears on the transmission. As a result of this development, a larger load is transmitted from the force transmission surface FTF of the gear hole slot SHS to the force receiving surface FRF of the smaller portion of the transmission slot key DBS.
本發明是基於在以相當軟材料(例如鋁合金)製作之傳動體DB之傳動體槽鍵上，使用以較硬材料(例如鋼材)所製作之傳動體***件從而可避免過度磨損之發現。根據本發明，一傳動體被提供一複合槽鍵，複合槽鍵包含以傳動體之材料製作之第一部分和以不同、較硬材料製作之第二部分。複合槽鍵之第二部分是一***部，其包含一受力表面。***部可將傳遞至其上之力經複合槽鍵之第一部分傳送至傳動體上。複合槽鍵，和特別是較硬且構成複合槽鍵一部分之***部，使用在高性能之後自行車輪轂時能避免損壞較軟傳動體材料。The present invention is based on the discovery that a transmission insert made of a relatively hard material (e.g., steel) is used on a transmission slot key of a transmission body DB made of a relatively soft material such as an aluminum alloy to avoid excessive wear. In accordance with the present invention, a transmission body is provided with a composite slot key comprising a first portion made of a material of the transmission body and a second portion made of a different, relatively hard material. The second portion of the composite slot key is an insert that includes a force bearing surface. The insert transmits the force transmitted thereto to the transmission through the first portion of the composite slot key. The composite slot key, and particularly the insert that is relatively stiff and forms part of the composite slot key, avoids damage to the softer transmission material when used in high performance bicycle hubs.
本發明係關於一用於自行車輪轂之傳動體。傳動體包含至少一複合槽鍵，複合槽鍵係在輪轂之傳動體之外表面。傳動體和複合槽鍵之第一部分是以相當軟性材料製作。複合槽鍵包含第二部分，第二部分包含至少一***部，***部係以較硬材料製作。***部較佳是利用傳動體材料上之一重疊部，固定在傳動體上。The present invention relates to a transmission body for a bicycle hub. The transmission body includes at least one composite groove key, and the composite groove key is attached to the outer surface of the transmission body of the hub. The first part of the transmission body and the composite slot key is made of a relatively soft material. The composite slot key includes a second portion, the second portion including at least one insertion portion, the insertion portion being made of a relatively hard material. Preferably, the insertion portion is secured to the transmission body by an overlap on the body of the transmission.
本發明主要目的是提供一鋼質或硬的***部，其可有效抵抗對以如鋁合金製成之相對較軟傳動體槽鍵之磨損。該磨損可能是以硬質材料(例如鋼材)製作之薄齒輪孔齒槽 之力傳遞面施加非常高之負荷時所產生。SUMMARY OF THE INVENTION A primary object of the present invention is to provide a steel or rigid insert that is effective against wear on relatively soft drive slot keys such as aluminum alloy. The wear may be a thin gear hole cogging made of a hard material such as steel. When the force transmission surface is applied with a very high load.

參照圖2至6所示，用於自行車後輪轂(rear bicycle wheel hub；未繪示，原則上可參閱圖1)之一傳動體(drive body)10是一具有複數槽鍵(splines)之筒狀體。有三種槽鍵設置在傳動體10。一中間槽鍵(centering spline)12是作為鏈輪(sprockets；未繪示，原則上可參閱圖1)組裝在傳動體10上時之參考。與傳動體10連成一體之一普通槽鍵(regular spline)14，當然該普通槽鍵14以製作傳動體10所用之相同材料製成。一複合槽鍵(composite spline)16包含與傳動體10成為一體之一第一部分18，該第一部分18以製作傳動體10所用之相同材料製成。複合槽鍵16亦包含一第二部分20，第二部分20包含一***部(insert)，製作***部之材料與傳動體10之材料是不同且較硬。普通槽鍵14均具有受力表面(force receiving surfaces)22，來自鏈輪之力係施加在與經 過受力表面22，特別是那些當力矩(torque)施加在鏈輪(圖1中之S)時，來自鏈輪孔齒(sprocket hole splines；SHS，如圖1所示)之力傳遞面(如圖1所示之FTF)之力。Referring to Figures 2 to 6, a drive body 10 for a bicycle bicycle hub (not shown, see in principle Figure 1) is a cylinder having a plurality of splines. Shape. There are three types of slot keys provided in the transmission body 10. A centering spline 12 is referred to as a sprocket (not shown, see in principle in FIG. 1) when assembled on the transmission 10. A conventional spline 14 is integrated with the transmission body 10. Of course, the conventional slot key 14 is made of the same material used to make the transmission body 10. A composite spline 16 includes a first portion 18 integral with the transmission body 10, the first portion 18 being formed of the same material used to make the transmission body 10. The composite slot key 16 also includes a second portion 20 that includes an insert and the material from which the insert is made is different and stiffer than the material of the actuator 10. The common slot keys 14 each have a force receiving surface 22, and the force from the sprocket is applied to The force-receiving surface 22, particularly those when the torque is applied to the sprocket (S in Figure 1), is the force transfer surface from the sprocket hole splines (SHS, as shown in Figure 1). The force of the FTF shown in Figure 1.
在複合槽鍵16上，有一受力表面(force receiving surfaces)24，該受力表面24形成在複合槽鍵16之***部或第二部分20上，其中對照以比較軟的材料製作之第一部分18，***部是以比較硬的材料製作。相對於用於製作傳動體10、槽鍵(12、14)和複合槽鍵16之第一部分18之較軟材料，用於製作***部或第二部分20之較硬材料較耐磨。由於習知之傳動體上之槽鍵與傳動體係相同材料製作，且習知之傳動體上並未有複合槽鍵，因此與習知之傳動體和其槽鍵相較，傳動體10和特別是槽鍵(12、14和16)會磨損較慢。再者，在***部20上與受力表面24相對處，有傳力表面(force transmitting surfaces)25(圖2和圖6)，力從***部20經由傳力表面25傳遞至第一部分18。關於此部分，將詳述於下。On the composite slot key 16, there is a force receiving surface 24 formed on the insertion portion or second portion 20 of the composite slot key 16, wherein the first portion is made of a relatively soft material. 18, the insertion portion is made of a relatively hard material. The harder material used to make the insert or second portion 20 is relatively wear resistant relative to the softer material used to make the transmission body 10, the slot keys (12, 14), and the first portion 18 of the composite slot key 16. Since the slot key on the conventional transmission body is made of the same material as the transmission system, and the conventional transmission body does not have a composite slot key, the transmission body 10 and especially the slot key are compared with the conventional transmission body and its slot key. (12, 14 and 16) will wear more slowly. Further, on the insertion portion 20, opposite to the force receiving surface 24, there are force transmitting surfaces 25 (Figs. 2 and 6), and the force is transmitted from the insertion portion 20 to the first portion 18 via the force transmitting surface 25. This section will be detailed below.
複合槽鍵16之第二部分是***部20，***部20包含一對之突片(tabs)26，突片26配合複合槽鍵16之第一部分18，以將***部20固持。複合槽鍵16之第一部分18係由三個凸起並沿軸向延伸之片斷部(sections)28所構成，其中片斷部28係與傳動體10一體成形。各片斷部28包含一受力表面29(圖6)，其承受來自***部20之傳力表面25所傳遞之力。兩周圍延伸之凹槽(在圖2以數字30標示)為3個片斷部28所界定。The second portion of the composite slot key 16 is the insertion portion 20, and the insertion portion 20 includes a pair of tabs 26 that engage the first portion 18 of the composite slot key 16 to retain the insertion portion 20. The first portion 18 of the composite slot key 16 is formed by three projections and axially extending sections 28, wherein the segment portion 28 is integrally formed with the transmission body 10. Each segment portion 28 includes a force bearing surface 29 (Fig. 6) that receives the force transmitted from the force transmitting surface 25 of the insertion portion 20. The two circumferentially extending grooves (indicated by numeral 30 in Figure 2) are defined by three segment portions 28.
圖3至圖5顯示***部20如何被固持，以成為複合槽鍵16之一部分。***部20可以沖壓一片鋼板來製作，其方法是將鋼板放置於衝頭(punch)和衝模(die)之間，衝模被製作，使其可製作出具如***部20之外形之部件。當衝頭被驅向衝模時，鋼板被剪切而形成***部20。當沖壓方法被用於製作帶突片26之***部20時，上表面32會與衝頭接觸，而下表面34會與衝模接觸，***部20之側邊，包含突片26之側邊(特別如圖5所示)會有輪廓面(contoured surface)。鄰近***部20之下表面34之***部20和突片26之部分側面有實質上平滑、垂直之切剪區，其以數字36來標示。鄰近***部20之上表面32之***部20和突片26之部分側面則具有一帶倒角(angled)、呈錐狀(tapered)、有些粗糙或顯現鋸齒狀之斷裂區(jagged breakaway region)，其在圖5以數字38來標示。此在***部20上自然產生之錐形部(taper)是因使用沖壓方法製作***部20之結果。此特徵有益於***部20固定在傳動體10上，如果凹槽30(圖2)按一寬度尺寸製作，該寬度小於***部20之突片26上以編號36標示之實質上平滑、垂直之切剪區附近之寬度，以及如果凹槽30之該寬度約略等於突片26上鋸齒狀之斷裂區與上表面32連接部分之寬度時。突片26然後可放置於凹槽30旁，如此突片26會與凹槽30對齊。接著施力在***部20之受力表面24上，將突片26壓入凹槽30內，此時***部20會向前，往順時鐘方向移動(如圖2所示)，直到***部20到達圖2上方所顯示的位置上。在該位置上，***部20之傳力表面25會接觸複合槽鍵 16之第一部分18之片斷部28之受力表面29。因為突片26之局部的寬度寬於凹槽30之寬度，且因為突片26是以較傳動體10與片斷部28之材料相對硬的材料所製作，因此突片26將會移除複合槽鍵16之第一部分18之片斷部28之部分材料，造成如圖3與圖4所顯示之底切(undercut)的情形發生。其結果是***部20在複合槽鍵16上會因突片26與片斷部28之局部間之相互作用(co-action)，而被緊固於其所在位置上。片斷部28界定凹槽30之構造，引人聯想起鳩尾接合。3 through 5 show how the insertion portion 20 is held to become part of the composite slot key 16. The insertion portion 20 can be formed by punching a single steel plate by placing a steel plate between a punch and a die, and the die is fabricated so that a member having a shape other than the insertion portion 20 can be produced. When the punch is driven toward the die, the steel sheet is sheared to form the insertion portion 20. When the stamping method is used to make the insertion portion 20 with the tabs 26, the upper surface 32 will contact the punch, and the lower surface 34 will contact the die, and the sides of the insertion portion 20, including the sides of the tabs 26 ( In particular, as shown in Figure 5, there will be a contoured surface. The insert portion 20 adjacent the lower surface 34 of the insertion portion 20 and a portion of the side of the tab 26 have substantially smooth, vertical cut regions, which are designated by the numeral 36. The insertion portion 20 adjacent to the upper surface 32 of the insertion portion 20 and a portion of the side surface of the tab 26 have an angled, tapered, somewhat rough or jagged breakaway region. It is indicated by the numeral 38 in FIG. This taper naturally generated on the insertion portion 20 is a result of the insertion of the insertion portion 20 by a press method. This feature is advantageous for the insertion portion 20 to be secured to the transmission body 10, if the recess 30 (Fig. 2) is formed in a width dimension that is substantially smaller than the tab 26 of the insertion portion 20, indicated by the numeral 36, substantially smooth, vertical The width of the vicinity of the cut zone and if the width of the groove 30 is approximately equal to the width of the portion of the jagged fracture zone and the upper surface 32 of the tab 26. The tab 26 can then be placed beside the recess 30 such that the tab 26 will align with the recess 30. Then, the force is applied to the force receiving surface 24 of the insertion portion 20, and the tab 26 is pressed into the groove 30. At this time, the insertion portion 20 will move forward and clockwise (as shown in FIG. 2) until the insertion portion. 20 reaches the position shown at the top of Figure 2. In this position, the force transmitting surface 25 of the insertion portion 20 contacts the composite slot key The force surface 29 of the segment 28 of the first portion 18 of 16. Because the width of the portion of the tab 26 is wider than the width of the recess 30, and because the tab 26 is made of a relatively stiffer material than the material of the actuator 10 and the segment 28, the tab 26 will remove the composite slot. Part of the material of the segment 28 of the first portion 18 of the key 16 causes an undercut as shown in Figures 3 and 4. As a result, the insertion portion 20 is fastened to the composite groove key 16 by the co-action between the tab 26 and the portion of the segment portion 28. The segment portion 28 defines the configuration of the recess 30, which is reminiscent of the dovetail joint.
如圖3與圖4所示，傳動體10之一部分，特別是複合槽鍵16之第一部分18之片斷部28之一些部分與***部20之一些部分，特別是突片26之一些部分為重疊，如此***部20可在複合槽鍵16上其所在之處被固持。在使用時，***部20之受力表面24會承受高的力負荷(force loading)；而這些力量會將***部20推入複合槽鍵16之第一部分18之片斷部28，如此這些力量會被傳遞至且經過***部20，到達複合槽鍵16之第一部分18，其中複合槽鍵16之第一部分18提供大的受力面積及分散(resolve)受力。As shown in Figures 3 and 4, a portion of the transmission body 10, particularly portions of the segment portion 28 of the first portion 18 of the composite slot key 16, overlaps portions of the insertion portion 20, particularly portions of the tab 26. Thus, the insertion portion 20 can be held where it is located on the composite slot key 16. In use, the stressed surface 24 of the insertion portion 20 will experience a high force loading; these forces will push the insertion portion 20 into the segment portion 28 of the first portion 18 of the composite slot key 16, such that the force will It is passed to and through the insert 20 to the first portion 18 of the composite slot key 16, wherein the first portion 18 of the composite slot key 16 provides a large area of force and a reactive force.
***部20被確實地固定而使其可避免相對於傳動體10，沿軸向移動(axial movement)。突片26和複合槽鍵16之片斷部28間之齧合讓***部20不在兩軸方向(both axial directions)移動。從結構上可確知各突片26本身和複合槽鍵16之第一部分18之相鄰兩片斷部28間之齧合確實可避免***部20相對於傳動體10沿軸向(兩軸方向)移動。每一突片26之一側邊與鄰近複合槽鍵16之第一部分18之片斷部28間之 抵接可避免傳動體10和***部20之間在一第一軸向上產生相對運動；而每一突片26之另一側邊與鄰近複合槽鍵16之第一部分18之片斷部28間之抵接可避免傳動體10和***部20之間在一第二軸向(相反於第一軸向)上產生相對運動。再者，***部20被確實地固定而使其可避免沿徑向移動(radial movement)-在兩徑向上，因為***部20上各突片26之兩成對重疊部(two paired overlapped portions)40在傳動體10間被確實固持住，特別是固持在傳動體10之外表面42和複合槽鍵16之第一部分18之片斷部28之兩成對之重疊部44間。再者，具兩成對之重疊部40之單一突片26和複合槽鍵16之第一部分18之兩相鄰片斷部28之重疊部44間之卡合可使傳動體10與***部20之間避免在徑向上移動。突片26和複合槽鍵16之第一部分18之片斷部28間之摩擦接觸(以及單一突片26和複合槽鍵16之第一部分18之相鄰片斷部28之摩擦接觸)可阻止***部20和傳動體10之間發生相對周圍方向(在兩方向上)運動(circumferential movement)。然而，在***部20上之傳力表面25(圖2和圖6)和在複合槽鍵16之第一部分18之片斷部28上之受力表面29間之抵接可確實防止***部20相對於傳動體10，在順時鐘周圍方向運動。此外，從結構上可確知當力傳遞通過鏈輪S之力傳遞面FTF(圖1)到具有一特定表面積(given surface area)之***部20之受力表面24之部分地方上時，該力會接著從***部20傳遞到複合槽鍵16之第一部分18之片斷部28之受力表面29上，而且該些受力表面29所具有的表面積實質上大於該特定表 面積。如此，複合槽鍵16之相對硬質***部20正可用來承受在小特定面積上之高度集中施力(highly concentrated forces)，並將該些力傳送至表面積實質上大於該特定面積之較軟質之傳動體材料上。此種結構可使槽鍵12和14較為耐磨。The insertion portion 20 is securely fixed so as to avoid axial movement relative to the transmission body 10. The engagement between the tab 26 and the segment portion 28 of the composite slot key 16 causes the insertion portion 20 not to move in both axial directions. It is structurally known that the engagement between each tab 26 itself and the adjacent two segments 28 of the first portion 18 of the compound slot key 16 does prevent the insertion portion 20 from moving axially (two-axis direction) relative to the transmission body 10. . One side of each tab 26 is adjacent to the segment 28 of the first portion 18 adjacent the composite slot key 16. The abutment prevents relative movement between the transmission body 10 and the insertion portion 20 in a first axial direction; and the other side of each tab 26 is adjacent to the segment portion 28 of the first portion 18 adjacent the composite slot key 16. The abutment prevents relative movement between the transmission body 10 and the insertion portion 20 in a second axial direction (opposite to the first axial direction). Furthermore, the insertion portion 20 is securely fixed so as to avoid radial movement - in both radial directions, because of the two paired overlapped portions of the tabs 26 on the insertion portion 20. 40 is held between the transmission bodies 10, in particular between the outer surface 42 of the transmission body 10 and the two overlapping portions 44 of the segment portion 28 of the first portion 18 of the composite slot key 16. Furthermore, the engagement between the single tab 26 of the two pairs of overlapping portions 40 and the overlapping portions 44 of the two adjacent segments 28 of the first portion 18 of the composite slot key 16 allows the transmission body 10 and the insertion portion 20 to be engaged. Avoid moving in the radial direction. The frictional contact between the tab 26 and the segment portion 28 of the first portion 18 of the composite slot key 16 (and the frictional contact of the single tab 26 with the adjacent segment portion 28 of the first portion 18 of the composite slot key 16) prevents the insertion portion 20 from being blocked. A relative circumferential direction (in both directions) occurs between the transmission body 10 and the transmission body 10. However, the abutment between the force transmitting surface 25 (Figs. 2 and 6) on the insertion portion 20 and the force receiving surface 29 on the segment portion 28 of the first portion 18 of the composite groove key 16 can surely prevent the insertion portion 20 from being opposed. The transmission body 10 moves in a direction around the clock. Further, it is structurally known that when a force is transmitted through a force transmitting surface FTF (Fig. 1) of the sprocket S to a portion of the force receiving surface 24 of the insertion portion 20 having a specific surface area, the force is It will then be transferred from the insertion portion 20 to the stressed surface 29 of the segment portion 28 of the first portion 18 of the composite slot key 16, and the force-receiving surfaces 29 will have a surface area substantially larger than the particular surface. area. As such, the relatively rigid insert 20 of the composite slot key 16 can be used to withstand highly concentrated forces on a small specific area and transfer the forces to a softer surface having a surface area substantially greater than the particular area. On the drive body material. This configuration allows the slot keys 12 and 14 to be relatively wear resistant.
可確知的是***部20(之後以***部(inserts)相稱)可依需要具曲度(curvature)，且其曲度與***部20所緊靠之傳動體10之外表面42之曲度係相配合。在***部20以沖壓方式之實施例中，此曲度可容易地藉由用於沖壓之工具來產生。It can be ascertained that the insertion portion 20 (later commensurate with the insertions) can have a curvature as needed, and its curvature is the curvature of the outer surface 42 of the transmission body 10 against which the insertion portion 20 abuts. Match. In embodiments where the insert 20 is stamped, this curvature can be easily produced by a tool for stamping.
在圖5中，***部20之突片26之側邊之錐狀部(tapered portions)38是相當粗糙。這是***部20以前述沖壓製造而自然所得的粗糙度的表現。在突片26***片斷部28並產生底切(undercut)之前(特別如圖3與圖4所示)，錐狀部38之這些表面可被稍微磨平。然而，可知道的是突片26之側邊之粗糙有助於增加摩擦抓力，其可使複合槽鍵16之***部20更緊固在其所在位置上。In Fig. 5, the tapered portions 38 of the sides of the tabs 26 of the insertion portion 20 are rather rough. This is an expression of the roughness naturally obtained by the insertion portion 20 by the aforementioned press manufacturing. These surfaces of the tapered portion 38 may be slightly smoothed before the tab 26 is inserted into the segment portion 28 and an undercut is created (as particularly shown in Figures 3 and 4). However, it will be appreciated that the roughness of the sides of the tab 26 helps to increase the frictional grip, which allows the insertion portion 20 of the composite slot key 16 to be more securely secured in its position.
在圖6中，顯示之傳動體具有三個複合槽鍵。但可理解的是本發明的許多效益，也可由具一複合槽鍵之傳動體來達成。確實，根據本發明，傳動體會具有至少一複合槽鍵。In Figure 6, the drive body shown has three composite slot keys. However, it will be appreciated that many of the benefits of the present invention can also be achieved by a transmission having a composite slot key. Indeed, in accordance with the present invention, the transmission body will have at least one composite slot key.
第二實施例之具複合槽鍵之傳動體在圖7中以編號50來標示。傳動體50類似傳動體10，除傳動體有不同的複合槽鍵之安排。在圖7中，複合槽鍵52包含與複合槽鍵52一體 製成和以同樣材料製作之一第一部分54。複合槽鍵52另包含一第二部分56，其包含一***部(insert)，該***部以不同於傳動體50之材料，且較傳動體50之材料為硬之材料所製作。在複合槽鍵52中，有一受力表面58，該受力表面58形成於***部或複合槽鍵52之第二部分56上。傳動體50包括一定位槽鍵(locator spline)60和普通槽鍵(regular splines)62。第二部分和***部56以較硬的材料製作，使其可較以較軟材料製作之傳動體50、定位槽件60、普通槽鍵62及複合槽鍵52之第一部分54等有較佳的耐磨性。由於傳統傳動體上僅具有和傳動體10以相同軟質材料製作之槽鍵及不包含具有至少一以硬質材料製作之***部之槽鍵16，因此相較於傳統傳動體，傳動體50，特別是槽鍵52、60和62磨損速度較慢。The transmission body with the composite slot key of the second embodiment is designated by the numeral 50 in FIG. The transmission body 50 is similar to the transmission body 10 except that the transmission body has different arrangements of composite slot keys. In FIG. 7, the composite slot key 52 is integrated with the composite slot key 52. One of the first portions 54 is made and made of the same material. The composite slot key 52 further includes a second portion 56 that includes an insert that is made of a material that is different from the material of the transmission body 50 and that is harder than the material of the transmission body 50. In the composite slot key 52, there is a force bearing surface 58 formed on the second portion 56 of the insert or composite slot key 52. The transmission body 50 includes a locator spline 60 and regular splines 62. The second portion and the insertion portion 56 are made of a relatively hard material such that the transmission body 50, the positioning groove member 60, the common slot key 62, and the first portion 54 of the composite slot key 52, which are made of a softer material, are preferably better. Wear resistance. Since the conventional transmission body only has the slot key made of the same soft material as the transmission body 10 and does not include the slot key 16 having at least one insertion portion made of a hard material, the transmission body 50 is special compared to the conventional transmission body. It is the slot keys 52, 60 and 62 that wear at a slower speed.
複合槽鍵52之第二部分是***部56，其包含一單一三角狀突片64，突片64與複合槽鍵52之第一部分54配合，將***部56固定在適當位置上。複合槽鍵52之第一部分54係由二個凸起並沿軸向延伸之片斷部(sections)66所構成，其中片斷部66係與傳動體50一體成形。片斷部66係分離，且一同界定具三角形狀之一凹槽(recess)，該凹槽所具之三角形狀與突片64之三角形狀係互補。突片64有側壁68，側壁68係呈錐形(tapered)安排，因為如此，當側壁68從下表面70往上表面72延伸時，它們向彼此傾斜，此結構最清楚係顯示在圖9。在圖9中，片斷部66具有互補錐形(complementarily tapered)側壁74，且片斷部66之部分與插 入部56之突片64之部分係疊合，如此之構造可將***部牢靠地固定在複合槽鍵適當的位置上。側壁74可以被切割，使得當***件定位在複合槽鍵內時，側壁74是沿徑向延伸。片斷部66接著可被壓印(coined)或鍛粗(upset)，以使其具有圖9所示之一般形狀(general shape)。突片64之錐狀部可同圖2至圖6中所描述之錐狀部一樣的方法獲得，若***部56也是用衝頭與衝模沖壓製作。如圖9所示，傳動體50之一部分，特別是複合槽鍵52之第一部分54之片斷部66之部分與***部56之部分，特別是突片64之部分將重疊，如此***部56可被固持在複合槽鍵52之適當位置。The second portion of the composite slot key 52 is an insertion portion 56 that includes a single triangular tab 64 that cooperates with the first portion 54 of the composite slot key 52 to secure the insertion portion 56 in place. The first portion 54 of the composite slot key 52 is formed by two projections 66 extending axially, wherein the segment portion 66 is integrally formed with the transmission body 50. The segment portion 66 is separated and together define a recess having a triangular shape having a triangular shape complementary to the triangular shape of the tab 64. The tabs 64 have side walls 68 which are tapered in arrangement because, as the side walls 68 extend from the lower surface 70 to the upper surface 72, they are inclined toward each other, the structure of which is best seen in FIG. In Fig. 9, the segment portion 66 has a complementary angular side wall 74, and the portion of the segment portion 66 is interspersed with The portions of the tabs 64 of the entry portion 56 are superposed so that the insertion portion can be securely held in place at the appropriate position of the composite slot key. The side wall 74 can be cut such that the side wall 74 extends radially when the insert is positioned within the composite slot key. The segment portion 66 can then be coined or upset so that it has the general shape shown in FIG. The tapered portion of the tab 64 can be obtained in the same manner as the tapered portion described in Figures 2 through 6, if the insert portion 56 is also stamped and punched. As shown in Figure 9, a portion of the transmission body 50, particularly the portion of the segment portion 66 of the first portion 54 of the composite slot key 52, and a portion of the insertion portion 56, particularly the portion of the tab 64, will overlap such that the insertion portion 56 can It is held in place at the composite slot key 52.
如第一實施例之***部20一樣，***部56被確實固定，以避免相對於傳動體50沿徑向或軸向移動。作用在***部56之受力表面58之力被傳送至複合槽鍵52之第一部分54。一方面，在突片64一側之側壁68和複合槽鍵52之第一部分54之相鄰片斷部66間之共同作用(coaction)下及另一方面，在突片64之另一側之側壁68和複合槽鍵52之第一部分54之相鄰片斷部66之共同作用下，可將***部56固持，使其避免相對於傳動體50(反之亦然)做軸向運動(axial movement)。同時，***部56之下表面70和傳動體50之外表面76間之共同作用可避免***部56相對於傳動體50在徑向上向內移動。再者，在突片64各側邊之側壁68和複合槽鍵52之第一部分54之相鄰片斷部66間之共同作用可避免***部56相對於傳動體50在徑向上向外移動。As with the insertion portion 20 of the first embodiment, the insertion portion 56 is securely fixed to avoid radial or axial movement relative to the transmission body 50. The force acting on the stressed surface 58 of the insert 56 is transmitted to the first portion 54 of the composite slot key 52. On the one hand, under the coaction between the side wall 68 of the side of the tab 64 and the adjacent segment 66 of the first portion 54 of the composite slot key 52, and on the other hand, the side wall on the other side of the tab 64 Together with the adjacent segment portion 66 of the first portion 54 of the composite slot key 52, the insertion portion 56 can be retained to avoid axial movement relative to the transmission body 50 (or vice versa). At the same time, the interaction between the lower surface 70 of the insertion portion 56 and the outer surface 76 of the transmission body 50 prevents the insertion portion 56 from moving radially inward relative to the transmission body 50. Moreover, the interaction between the side walls 68 of the sides of the tabs 64 and the adjacent segments 66 of the first portion 54 of the composite slot key 52 prevents the insertion portion 56 from moving radially outward relative to the transmission body 50.
具複合槽鍵之傳動體之第三個實施例在圖10中以編號 80標示。傳動體80類似傳動體10和50，除傳動體有不同的複合槽鍵之安排。在圖10中，複合槽鍵82包含與傳動體80整合一起和以傳動體80相同材料製作之第一部分84。複合槽鍵82也包含一第二部分86，其包含一***部(insert)，該***部以不同於傳動體80之材料，且較傳動體50之材料為硬之材料所製作。在複合槽鍵82中，有一受力表面88，該受力表面88形成於***部或複合槽鍵82之第二部分86上。傳動體80包括一定位槽鍵(locator spline)90和普通槽鍵(regular splines)92。第二部分和***部86以較硬的材料製作，使其可較以較軟材料製作之傳動體80、定位槽件90、普通槽鍵92及複合槽鍵82之第一部分84等有較佳的耐磨性。A third embodiment of a transmission with a composite slot key is numbered in Figure 10 80 mark. The transmission body 80 is similar to the transmission bodies 10 and 50 except that the transmission body has different arrangements of composite slot keys. In FIG. 10, the composite slot key 82 includes a first portion 84 that is integrated with the transmission body 80 and that is fabricated from the same material as the transmission body 80. The composite slot key 82 also includes a second portion 86 that includes an insert that is made of a material that is different from the material of the transmission body 80 and that is harder than the material of the transmission body 50. In the composite slot key 82, there is a force bearing surface 88 formed on the second portion 86 of the insert or composite slot key 82. The transmission body 80 includes a locator spline 90 and regular splines 92. The second portion and the insertion portion 86 are made of a relatively hard material such that the transmission body 80 made of a softer material, the positioning groove member 90, the common groove key 92, and the first portion 84 of the composite groove key 82 are preferably provided. Wear resistance.
複合槽鍵82之第二部分是***部86，其包含兩一般形狀突片(regularly shaped tabs)94，突片94與複合槽鍵82之第一部分84配合，將***部86固定在適當位置上。複合槽鍵82之第一部分84包含三個凸起並沿軸向延伸之片斷部(sections)96和兩凸起之柱體98，其中片斷部96和柱體98全部與傳動體80整合一起。片斷部96係分離，並一同界定兩凹處；而柱體98位於該些凹處中。柱體98與凹處係同時以空心銑刀(hollow mill)形成。突片94各具有一穿越其中之開孔(bore)，這些開孔成錐狀，使得它們在頂部、靠近***部86之上表面100處有一給定直徑，而在底部、靠近下表面102之直徑小於該給定直徑。開孔在突片94之底部之直徑可和柱體98之直徑一樣或大於柱體98之直徑，如此***部86可 以被定位在複合槽鍵82中之適當位置上，如圖10接近上方處所示。作為將***部86固定於傳動體80上之手段，柱體98可被壓印(coined)或鍛粗(upset)，使得它們可變更短和增大它們的直徑。如果可能，部分之柱體98可與傳動體80結合，覆蓋部分之***部86，特別是部分之突片94，如圖12中清楚顯示的情形。如先前對***部所描述，***部86被確實固定，以避免相對於傳動體80沿徑向或軸向移動。作用在***部86之受力表面88之力被傳送至複合槽鍵82之第一部分84。The second portion of the composite slot key 82 is an insertion portion 86 that includes two generally shaped tabs 94 that cooperate with the first portion 84 of the composite slot key 82 to secure the insertion portion 86 in place. . The first portion 84 of the composite slot key 82 includes three projections and axially extending sections 96 and two raised cylinders 98, wherein the segments 96 and the posts 98 are all integrated with the transmission 80. The segment portion 96 is separated and defines two recesses together; and the cylinder 98 is located in the recesses. The cylinder 98 and the recess are simultaneously formed by a hollow mill. The tabs 94 each have a bore therethrough which tapers such that they have a given diameter at the top, near the upper surface 100 of the insert 86, and at the bottom, near the lower surface 102. The diameter is less than the given diameter. The diameter of the opening at the bottom of the tab 94 may be the same as or larger than the diameter of the cylinder 98, such that the insertion portion 86 may To be positioned in position in the composite slot key 82, as shown in Figure 10 near the top. As a means of securing the insertion portion 86 to the transmission body 80, the cylinders 98 can be coined or upset such that they can be shortened and their diameters increased. If possible, a portion of the post 98 can be coupled to the drive body 80 to cover a portion of the insert 86, particularly a portion of the tab 94, as is best seen in FIG. As previously described for the insert, the insert 86 is securely secured to avoid radial or axial movement relative to the drive body 80. The force acting on the stressed surface 88 of the insert 86 is transmitted to the first portion 84 of the composite slot key 82.
圖13中顯示以編號110所標示之具複合槽鍵之傳動體之再一實施例。在此傳動體110中，具有一突片114之***部112被提出，其中突片114部分地被兩錐形不完全開孔所界定。***部112可被兩柱體116所固持，兩柱體116可如前面實施例一樣，被壓印(coined)或鍛粗(upset)，以與***部112之部分疊合，藉此將其固定在複合槽鍵118上，如圖15所示。如先前對***部所描述，***部112可被確實固定，以避免相對於傳動體110沿徑向或軸向移動。作用在***部112之力被傳送至複合槽鍵118之第一部分。A further embodiment of a transmission having a composite slot key, designated by the numeral 110, is shown in FIG. In this transmission body 110, an insertion portion 112 having a tab 114 is proposed, wherein the tab 114 is partially defined by two tapered incomplete openings. The insertion portion 112 can be held by the two cylinders 116, and the two cylinders 116 can be coined or upset as in the previous embodiment to overlap the portion of the insertion portion 112, thereby It is fixed to the composite slot key 118 as shown in FIG. As previously described for the insert, the insert 112 can be securely secured to avoid radial or axial movement relative to the drive body 110. The force acting on the insert 112 is transmitted to the first portion of the composite slot key 118.
第五個具複合槽鍵之傳動體之實施例被標示以120，並顯示在圖16中。複合槽鍵122包含與傳動體120整合一起和以傳動體120相同材料製作之第一部分124，以及一第二部分126，該第二部分126為一***部。***部126通常具矩形形狀，且具有穿過其中且標示為127之錐狀開孔。鉚釘128被收容於開孔127內，並延伸穿過傳動體120，藉此將第二 部分126固定且緊固在傳動體120上。鉚釘128之球根狀部分(bulbous portion)129頂住傳動體120之內側表面，而鉚釘套管131之一錐狀部分抵靠在***部126內之錐狀開孔127。如此，鉚釘128將***部126固定在傳動體120，以及避免***部126和傳動體120之間在任一軸向上產生相對移動。鉚釘128同樣用於避免***部126從傳動體120在徑向上往外移動，而***部126與傳動體120間之相互作用可避免***部126相對於傳動體120在徑向上往內移動。可了解的是在前述之實施例中，那些將傳動體120之材料所製作之柱體弄平，以覆蓋在部分之***部之所在，可使用鉚釘或其他連接裝置(connector)來取代柱體。當然，柱體可以用來取代鉚釘128，且將其壓平以覆蓋在部分之***部上。An embodiment of the fifth transmission with a compound slot key is labeled 120 and is shown in FIG. The composite slot key 122 includes a first portion 124 that is integrated with the transmission body 120 and is made of the same material as the transmission body 120, and a second portion 126 that is an insertion portion. The insert 126 is generally rectangular in shape and has a tapered opening therethrough and designated 127. The rivet 128 is received in the opening 127 and extends through the transmission body 120, thereby Portion 126 is fixed and fastened to transmission body 120. The bulbous portion 129 of the rivet 128 bears against the inside surface of the transmission body 120, and one of the tapered portions of the rivet sleeve 131 abuts against the tapered opening 127 in the insertion portion 126. As such, the rivet 128 secures the insertion portion 126 to the transmission body 120 and avoids relative movement between the insertion portion 126 and the transmission body 120 in either axial direction. The rivet 128 is also used to prevent the insertion portion 126 from moving radially outward from the transmission body 120, and the interaction between the insertion portion 126 and the transmission body 120 prevents the insertion portion 126 from moving radially inward relative to the transmission body 120. It will be appreciated that in the foregoing embodiments, the cylinders made of the material of the transmission body 120 are flattened to cover the portion of the insertion portion, and rivets or other connectors may be used instead of the cylinders. . Of course, the post can be used to replace the rivet 128 and flatten it to cover the portion of the insert.
第六個具複合槽鍵之傳動體之實施例在圖16中被標示為130。傳動體130包含複合槽鍵132，其包含一第一部分134。第一部分134與傳動體130整合一起且為傳動體130之一部分。複合槽鍵132更包含一***部136，***部136為矩形並包含兩下垂突片(depending tabs)138。突片138係與***部136成一體，並大體上從***部136之主要部分(major portion)以垂直角度延伸。標示139之開孔形成在傳動體130上，且部分之開孔139延伸穿過複合槽鍵132之第一部分134之一部分。突片138***開孔139，並與開孔139之側壁摩擦接觸，藉此將***部136固定在如圖19上方部分所示之複合槽鍵132上一例示之位置上。在圖19與圖20中，繪示之突片138具有大錐度(exaggerated taper)，其中各突片138之自由 端係較其彎折端為寬。大錐度之繪示係為例示在***部136和傳動體130之間可產生摩擦接觸(frictional engagement)之方法。如圖20所示，當各突片138之自由端或末端較另一端(突片138之最接近之端部)為略寬，而且自由端之寬度較開孔139之直徑略為大。突片138會推移一些傳動體130之材料，且將其在徑向、向內推送，從而產生概略可被稱為肩部(編號140)之結構。如放大之圖20所示，一些傳動體130之材料(以編號142標示)會回彈，且會確實覆蓋各突片138之部分處。在突片並非錐狀但較開孔139之直徑略為大之例子中，相同的覆蓋狀況也可獲得，雖然覆蓋是在微小(microscopic)程度。An embodiment of the sixth transmission with a compound slot key is designated 130 in FIG. The transmission body 130 includes a composite slot key 132 that includes a first portion 134. The first portion 134 is integrated with the transmission body 130 and is part of the transmission body 130. The composite slot key 132 further includes an insertion portion 136 that is rectangular and includes two depending tabs 138. The tab 138 is integral with the insertion portion 136 and extends generally at a vertical angle from a major portion of the insertion portion 136. An opening of the numeral 139 is formed on the transmission body 130, and a portion of the opening 139 extends through a portion of the first portion 134 of the compound channel key 132. The tab 138 is inserted into the opening 139 and is in frictional contact with the side wall of the opening 139, thereby securing the insertion portion 136 to the position illustrated on the composite slot key 132 shown in the upper portion of FIG. In Figures 19 and 20, the tab 138 is shown as having an exclusive taper, wherein the tabs 138 are free. The end system is wider than the bent end. The large taper is shown to illustrate a method of creating a frictional engagement between the insert 136 and the drive body 130. As shown in Fig. 20, when the free end or end of each tab 138 is slightly wider than the other end (the closest end of the tab 138), the width of the free end is slightly larger than the diameter of the opening 139. The tab 138 will push the material of some of the drive body 130 and push it radially and inwardly to create a structure that may be referred to as a shoulder (number 140). As shown in enlarged view 20, the material of some of the drive body 130 (indicated by numeral 142) will rebound and will indeed cover portions of each tab 138. In the case where the tab is not tapered but is slightly larger than the diameter of the opening 139, the same coverage condition is also available, although the coverage is microscopic.
