Description
本發明係有關一種螺柱結構，尤指用於固定鏈輪之後輪框與齒輪盤之間的螺柱者。The invention relates to a stud structure, especially a stud used to fix the sprocket between the wheel frame and the gear plate.
按，習知透過鏈條將馬達動能傳遞至後輪以帶動車輪行進之車輛，需透過齒輪盤來固定鏈條，而齒輪盤之固定結構，請參閱第1~2圖所示，其係藉由二端分別具嵌合段(11)及螺紋段(12)之螺柱(1)將齒輪盤(2)固定於後輪框(3)。其中，位於後輪框(3)之齒盤座(31)形成一中心軸(32)，並於中心軸(32)環繞複數具襯套孔(331)之襯套(33)，使螺柱(1)之嵌合段(11)能嵌入襯套孔(331)內，且將齒輪盤(2)之通孔(21)穿置於齒盤座(31)之中心軸(32)，同時讓螺柱(1)之螺紋段(12)穿設於齒輪盤(2)之鎖孔(22)，並利用螺帽(4)鎖固，以便於齒輪盤(2)上裝設鏈條。Press, the conventional vehicle that transmits the kinetic energy of the motor to the rear wheels through the chain to drive the wheels to move, the chain needs to be fixed by the gear plate, and the fixed structure of the gear plate, please refer to the diagrams 1~2, which is based on two A stud (1) with a fitting section (11) and a thread section (12) at each end fixes the gear plate (2) to the rear wheel frame (3). Among them, the gear plate seat (31) located in the rear wheel frame (3) forms a central shaft (32), and the central shaft (32) surrounds a plurality of bushes (33) with bushing holes (331) to make the stud (1) The fitting section (11) can be inserted into the bushing hole (331), and the through hole (21) of the gear plate (2) is inserted into the central shaft (32) of the gear plate seat (31), and at the same time The threaded section (12) of the stud (1) is inserted into the lock hole (22) of the gear plate (2) and locked by the nut (4) to facilitate the installation of a chain on the gear plate (2).
然而，習知螺柱(1)之嵌合段(11)與襯套孔(331)並未完全密合，雖能利用嵌合段(11)與襯套(33)內壁之間的餘隙公差使後輪於高速旋轉時作為緩衝，但未密合的嵌合段(11)與襯套(33)內壁會隨著後輪框(3)旋轉而磨擦，長久下來則會造成螺柱(1)與襯套(33)磨損變形。However, the fitting section (11) of the conventional stud (1) and the bushing hole (331) are not completely tight, although the remaining space between the fitting section (11) and the inner wall of the bushing (33) can be used The clearance tolerance allows the rear wheel to act as a buffer during high-speed rotation, but the unclosed fitting section (11) and the inner wall of the bushing (33) will rub against the rear wheel frame (3) as the rear wheel frame (3) rotates. The column (1) and the bushing (33) are worn out and deformed.
為改善上述缺失，故中華民國公告第M588187號專利，係揭露一種「鏈輪降噪結構（一）」，其係於鏈輪與組立座間設有複數鎖固件，且於鎖固件之銷桿段上間隔設有數墊圈，使二墊圈與組立座之銷孔孔壁間形成供儲存潤滑油之儲油空間，以透過墊圈及潤滑油產生彈性緩衝效果，防止鎖固件之銷桿段與組立座之銷孔因碰撞磨擦而快速磨損。然而，上述先前技術雖能透過於銷桿段設置墊圈來提升鎖固件與銷孔之密合度，並利用潤滑油以避免銷桿段組裝於銷孔時擠壓斷裂，但後輪框於高速轉動時會產生熱能，使儲油空間內之潤滑油因高溫變質而導致矽膠硬化，造成矽膠提早磨損、斷裂，並因矽膠斷裂而破壞鎖固件與銷孔的密合度，使鎖固件於後輪框旋轉時偏擺磨損，因此，顯然無法確實解決鎖固件磨損與噪音問題。In order to improve the above-mentioned deficiencies, the Republic of China Announcement No. M588187 Patent discloses a "sprocket noise reduction structure (1)", which is connected between the sprocket and the assembly seat and is provided with a plurality of locking members, and the pin section of the locking member There are several washers in the upper space, so that the two washers and the pin hole wall of the assembly seat form an oil storage space for storing lubricating oil, so as to produce an elastic buffer effect through the washers and lubricating oil, and prevent the pin section of the locking member from the assembly seat. The pin hole is quickly worn out due to collision and friction. However, although the above-mentioned prior art can improve the tightness of the locking member and the pin hole by arranging a washer on the pin section and using lubricating oil to prevent the pin section from being crushed and broken when the pin section is assembled in the pin hole, the rear wheel frame rotates at a high speed. When the heat is generated, the lubricating oil in the oil storage space will be hardened due to high temperature deterioration, which will cause the silicone to wear and break prematurely. The fracture of the silicone will damage the tightness of the locking member and the pin hole, and make the locking member in the rear wheel frame. The deflection wears when rotating, so it is obviously unable to solve the problem of wear and noise of the lock member.
有鑑於習知螺柱之嵌合段與襯套孔並未完全密合，使螺柱與襯套內壁隨著後輪框旋轉而磨損變形，另外，改良之銷桿段雖能透過設置墊圈來提升鎖固件與銷孔之密合度，但墊圈與墊圈之間的潤滑油會因高溫變質而導致矽膠硬化，造成矽膠提早磨損、斷裂，故顯然具待改善之缺失。In view of the fact that the fitting section of the conventional stud and the bushing hole are not completely tight, the inner wall of the stud and the bushing is worn and deformed with the rotation of the rear wheel frame. In addition, the improved pin section can be provided with a washer To improve the tightness between the locking member and the pin hole, the lubricating oil between the washer and the washer will harden the silicone rubber due to high temperature deterioration, which will cause the silicone rubber to wear and break prematurely. Therefore, it is obvious that there is a lack of improvement.
是以，本發明之目的係透過於螺柱設中心穿孔，並於螺柱嵌合段的環溝之間設流道及導引孔，使潤滑油、熱氣、蒸氣及凝結水能由流道經導引孔由中心穿孔排出，且藉由套設於環溝之O形環達成減震之目的。Therefore, the purpose of the present invention is to provide a central perforation in the stud, and to provide a flow channel and a guide hole between the annular grooves of the stud fitting section, so that the lubricating oil, hot air, steam and condensed water can pass through the flow channel. It is discharged from the central perforation through the guide hole, and the purpose of shock absorption is achieved by the O-ring sleeved in the ring groove.
為達前述目的，本發明提供一種用於固定齒輪盤之螺柱結構，該螺柱包含一嵌合段及一螺紋段，該嵌合段供嵌卡固定於一後輪框其齒盤座之襯套孔內，該螺紋段供與螺帽相螺合以便將螺柱鎖固於一齒輪盤，使齒輪盤藉螺柱固定於後輪框，其特徵在於︰該螺柱設有一中心穿孔，且於嵌合段間隔設置第一環溝、第二環溝及第三環溝，並於第一、第二及第三環溝之間設至少一流道，位於流道與第一、第二環溝之間及第二、第三環溝之間設有貫通中心穿孔之導引孔，且於第一、第二及第三環溝內分別套置至少一O形環，並使第一及第二環溝之寬度大於O形環之寬度，讓O形環能於環溝內位移。In order to achieve the foregoing objective, the present invention provides a stud structure for fixing a gear disk. The stud includes a fitting section and a threaded section. In the bushing hole, the threaded section is used for screwing with the nut to lock the stud to a gear plate, so that the gear plate is fixed to the rear wheel frame by the stud. The feature is that the stud is provided with a central perforation, In addition, a first ring groove, a second ring groove, and a third ring groove are arranged at intervals in the fitting section, and at least a first channel is provided between the first, second and third ring grooves, which are located between the flow channel and the first and second ring grooves. Between the ring grooves and between the second and third ring grooves are provided guide holes penetrating the central perforation, and at least one O-ring is respectively sleeved in the first, second and third ring grooves, and the first And the width of the second ring groove is greater than the width of the O-ring, so that the O-ring can move in the ring groove.
基於上述，透過設於第一、第二及第三環溝之O形環使螺柱嵌入齒盤座之襯套孔後，藉由O形環貼合於襯套孔壁面，進而將螺柱導正對應於襯套孔中心，並於後輪框高速轉動時，達成減震及吸震之功效，此外，沾附於嵌合段之潤滑油或因後輪框高速轉動產生之熱氣、蒸氣及凝結水，能經流道之導引孔由中心穿孔排出，以避免潤滑油因高溫變質而致使O形環硬化，增進散熱效果，並延長螺柱與襯套之使用壽命。Based on the above, after the stud is inserted into the bushing hole of the gear plate seat through the O-rings provided in the first, second and third ring grooves, the O-ring is attached to the wall of the bushing hole, and then the stud The guide corresponds to the center of the bushing hole and achieves shock absorption and shock absorption when the rear wheel frame rotates at high speed. In addition, the lubricating oil attached to the mating section or the heat, steam and heat generated by the high-speed rotation of the rear wheel frame The condensed water can be discharged from the central perforation through the guide hole of the runner to avoid the hardening of the O-ring due to high temperature deterioration of the lubricating oil, improve the heat dissipation effect, and prolong the service life of the stud and the bushing.
