Description
本發明是有關於一種軸封裝置，特別是指一種適用於機械設備之轉動軸的軸封裝置。The present invention relates to a shaft sealing device, and more particularly to a shaft sealing device suitable for use in a rotating shaft of a mechanical device.
請參閱圖1，一般攪拌用機械設備的構造設計，是於一液態槽(圖未示)上裝設一傳動軸9，以對該液態槽內的液體進行翻攪，而該機械設備通常是包含有一軸封裝置，藉以確保翻攪狀態的液體不會從該液態槽溢出。Referring to Figure 1, the general design of the mechanical device for agitating is to install a drive shaft 9 on a liquid tank (not shown) to tumbling the liquid in the liquid tank, and the mechanical equipment is usually A shaft sealing device is included to ensure that the liquid in the tumbling state does not overflow from the liquid tank.
一般來說，該機械軸封裝置包含一外殼7，及一樞設於該外殼7內的轉動機構8，該外殼7是供該傳動軸9穿設於其中，且該傳動軸9是裝設在該液態槽上，另外，該轉動機構8亦是固設於該傳動軸9上。Generally, the mechanical shaft sealing device comprises a casing 7 and a rotating mechanism 8 pivoted in the casing 7, the casing 7 is for the transmission shaft 9 to be inserted therein, and the transmission shaft 9 is installed In addition to the liquid tank, the rotating mechanism 8 is also fixed to the transmission shaft 9.
該外殼7具有一軸向延伸的軸孔70，及連通該軸孔70與外殼7外側空間的一流入口71與一流出口72，其中，該軸孔70是供該傳動軸9穿設，而氣體與冷卻介質可以經由該流入口71進入該軸孔70，再由該流出口72流出。The outer casing 7 has an axially extending shaft hole 70, and a first-class inlet 71 and a first-class outlet 72 communicating with the shaft hole 70 and the outer space of the outer casing 7, wherein the shaft hole 70 is for the transmission shaft 9 to pass through, and the gas The cooling medium can enter the shaft hole 70 via the inlet port 71 and flow out from the outlet port 72.
該機械軸封裝置更包含兩個分別置於該軸孔70兩相反端的固定封環73，而且所述固定封環73是夾設於該外殼7與轉動機構8之間，使得該二固定封環73只能沿著長軸方向移動。The mechanical shaft sealing device further comprises two fixed sealing rings 73 respectively disposed at opposite ends of the shaft hole 70, and the fixing sealing ring 73 is sandwiched between the outer casing 7 and the rotating mechanism 8, so that the two fixing seals The ring 73 can only move in the long axis direction.
該轉動機構8具有一保持環81、二壓縮環82、兩O型環83、二轉動環84，及一個套設於該傳動軸9上並隨其旋轉的軸套85。該保持環81、壓縮環82、O型環83，及轉動環84皆是組裝在一起而套設於該軸套85外周緣。該轉動機構8更具有多數個觸抵於該保持環81與壓縮環82之間的彈性件810，使得所述彈性件810可藉由其彈性而將該二壓縮環82朝遠離該保持環81的方向推離。The rotating mechanism 8 has a retaining ring 81, two compression rings 82, two O-rings 83, two rotating rings 84, and a sleeve 85 sleeved on the rotating shaft 9 and rotating therewith. The retaining ring 81, the compression ring 82, the O-ring 83, and the rotating ring 84 are assembled and sleeved on the outer periphery of the sleeve 85. The rotating mechanism 8 further has a plurality of elastic members 810 that are in contact with the retaining ring 81 and the compression ring 82, so that the elastic member 810 can move the two compression rings 82 away from the retaining ring 81 by its elasticity. The direction is pushed away.
此外，該轉動機構8更具有多數個連接該保持環81與壓縮環82的插銷811，以避免該二壓縮環82隨著傳動軸9轉動，而每一個壓縮環82的兩側面則是分別接觸彈性件810與轉動環84，且又將所述O型環83卡設於相對應的壓縮環82與轉動環84之間以提供密封效果，而每一轉動環84則是緊密地貼近於相對應的固定封環73。In addition, the rotating mechanism 8 further has a plurality of latches 811 connecting the retaining ring 81 and the compression ring 82 to prevent the two compression rings 82 from rotating with the transmission shaft 9, and the two sides of each compression ring 82 are respectively in contact. The elastic member 810 and the rotating ring 84, and the O-ring 83 is further clamped between the corresponding compression ring 82 and the rotating ring 84 to provide a sealing effect, and each rotating ring 84 is closely adjacent to the phase Corresponding fixed seal 73.
當該傳動軸9旋轉時，位於該軸孔70內的固定封環73會彈性地觸抵轉動環84，長時間使用下來，會在固定封環73與轉動環84之間產生磨耗，而所述彈性件810的彈力則會經由推離壓縮環82而使轉動環84移動，以確保固定封環73與轉動環84之間不會有縫隙產生，所以能夠降低該機械軸封內液體洩漏的機會。When the transmission shaft 9 rotates, the fixed sealing ring 73 located in the shaft hole 70 elastically contacts the rotating ring 84, and when used for a long time, the wear ring between the fixed sealing ring 73 and the rotating ring 84 may be worn. The elastic force of the elastic member 810 moves the rotating ring 84 by pushing away from the compression ring 82 to ensure that no gap is generated between the fixed sealing ring 73 and the rotating ring 84, so that liquid leakage in the mechanical shaft seal can be reduced. opportunity.
該機械軸封於製造上存在有幾個缺點，在安裝過程中，所述彈性件810必須先安裝在保持環81與壓縮環82之間，才能再安裝其他構件，而此安裝的主要問題在於：所述彈性件810很容易從該保持環81上掉落，造成組裝效率較差。There are several disadvantages in the manufacture of the mechanical shaft seal. During the installation process, the elastic member 810 must be installed between the retaining ring 81 and the compression ring 82 before other components can be installed. The main problem of this installation is that : The elastic member 810 is easily dropped from the retaining ring 81, resulting in poor assembly efficiency.
另一個問題則是，無法掌控二壓縮環82間相互補償的距離，當傳動軸9有較大的軸向貫動時，密封面亦有接觸不良的情況，進而造成該機械軸封內液體洩漏的機會提高。Another problem is that the mutual compensation distance between the two compression rings 82 cannot be controlled. When the transmission shaft 9 has a large axial movement, the sealing surface also has poor contact, thereby causing liquid leakage in the mechanical shaft seal. The opportunity to improve.
在一些專利前案中也有揭露過類似的機械軸封，例如美國公告第5,375,853號專利案與第3,888,495號專利案，該二專利案的缺點皆在於，其構造相當複雜而不易組裝或維修，再者，其保持環在運作時會承受很大的扭力。而美國公告第4,213,618號專利案雖然改善了不易組裝的缺點，但是其零組件還是很容易分離掉落，而不便於進行維修，所以，仍有需要對傳統機械軸封進行進一步的改善。Similar mechanical shaft seals have also been disclosed in a number of patents, such as U.S. Patent No. 5,375,853 and U.S. Patent No. 3,888,495, both of which are disadvantaged in that their construction is rather complicated and difficult to assemble or repair. The retaining ring will withstand a lot of torque when it is in operation. Although the U.S. Patent No. 4,213,618 has improved the shortcomings of being difficult to assemble, its components are easily separated and not easily repaired, so there is still a need for further improvement of the conventional mechanical shaft seal.
因此，本發明之目的，即在提供一種軸封裝置，其具有容易組裝與維修、元件不易分離，及具有較佳的平衡結構等優點。Accordingly, it is an object of the present invention to provide a shaft sealing device which has the advantages of ease of assembly and maintenance, difficulty in separation of components, and better balance structure.
於是，本發明軸封裝置主要是提供兩種實施型態，第一種是對稱卡匣式雙軸封，用以安裝於一機械設備之腔體與軸心間接傳動上，該軸封裝置包含至少一供該轉動軸穿設的本體組、兩個位於該本體組內且套設於該本體上的固定封環，及一樞設於該軸套上並與該轉動軸相連接的轉動單元，其中，該本體組的內側面界定出一供該轉動軸穿設於其中的軸孔，該二固定封環是於該軸孔內呈間隔設置。Therefore, the shaft sealing device of the present invention mainly provides two embodiments, the first one is a symmetric card type double shaft seal for mounting on a cavity and an indirect transmission of a mechanical device, the shaft sealing device comprises At least one body group for the rotating shaft, two fixed sealing rings disposed in the body group and sleeved on the body, and a rotating unit pivoted on the sleeve and connected to the rotating shaft The inner side surface of the body group defines a shaft hole through which the rotating shaft is disposed, and the two fixed sealing rings are disposed at intervals in the shaft hole.

其中一個壓縮環是位於該軸孔內並被該保持環的第一支腳所包圍，另外一個壓縮環則是位於該軸孔內並被該保持環的第二支腳所包圍，而且每一個壓縮環具有一外周部，及至少二形成於該外周部的切裁部，而且被該保持環的第一支腳所包圍的壓縮環，其切裁部是與第一支腳形成交錯狀態，被該保持環的第二支腳所包圍的壓縮環，其切裁部則是與第二支腳形成交錯狀態，而從該軸孔中央軸線到外周部的最短距離是定義為D4，從該軸孔中央軸線到切裁部的最短距離是定義為D3，且D3≦D1＜D4≦D2。One of the compression rings is located in the shaft hole and is surrounded by the first leg of the retaining ring, and another compression ring is located in the shaft hole and surrounded by the second leg of the retaining ring, and each The compression ring has an outer peripheral portion, and at least two cut portions formed on the outer peripheral portion, and the compression ring surrounded by the first leg of the retaining ring has a cut portion that is staggered with the first leg. a compression ring surrounded by the second leg of the retaining ring, the cutting portion is formed in a staggered state with the second leg, and the shortest distance from the central axis of the shaft hole to the outer peripheral portion is defined as D4. The shortest distance from the central axis of the shaft hole to the cutting portion is defined as D3, and D3 ≦ D1 < D4 ≦ D2.
所述彈性件是各別設置於該保持環的容置孔中，而且每個彈性件的兩端是分別觸抵該二壓縮環，該第一轉動環是觸抵於被該保持環的第一支腳所包圍的壓縮環，且該第二轉動環亦是觸抵於被該保持環的第二支腳所包圍的壓縮環。The elastic members are respectively disposed in the receiving holes of the retaining ring, and the two ends of each elastic member respectively touch the two compression rings, and the first rotating ring is in contact with the first ring a compression ring surrounded by a foot, and the second rotating ring also contacts a compression ring surrounded by the second leg of the retaining ring.
該軸套則是套設於該轉動軸上，而且依序在該軸套外周面套設有該第一轉動環、其中一壓縮環、保持環、另一壓縮環，以及第二轉動環，且該軸套具有一鄰近該第一轉動環且形成於該軸套之一端外周面的攪動件。The sleeve is sleeved on the rotating shaft, and the first rotating ring, one of the compression ring, the retaining ring, the other compression ring, and the second rotating ring are sleeved on the outer peripheral surface of the sleeve. And the sleeve has an agitating member adjacent to the first rotating ring and formed on an outer peripheral surface of one end of the sleeve.
當所述彈性件將該二壓縮環向外推抵時，便會藉由該二壓縮環的外周部與第一、二突塊相配合，使得其中一壓縮環是在該保持環的側面與第一突塊之間軸向移動，另一壓縮環則是在該保持環的另一側面與第二突塊之間軸向移動，當該二壓縮環與其所接觸之轉動環向外軸向移動時，將與該二固定封環形成互相抵推。When the elastic member pushes the two compression rings outward, the outer peripheral portion of the two compression rings cooperate with the first and second protrusions such that one of the compression rings is on the side of the retaining ring.

When the two compression rings are in contact with the rotating ring, the axial direction is outward. When moving, it will form a mutual offset with the two fixed seal rings.
本發明第二種實施型態，則採用卡匣式單軸封，主要是保留一個固定封環、第二轉動環，以及該保持環的第二支腳與第二突塊，至於前述實施型態中的另一個固定封環、第一轉動環，以及該保持環的第一支腳與第一突塊則予以減除；因此，當所述彈性件將該壓縮環向外推抵時，便會藉由該壓縮環的外周部與第二突塊相配合，使得該壓縮環是在該保持環的側面與第二突塊之間軸向移動，當該壓縮環向外軸向移動至接觸該第二轉動環時，便會連動該第一轉動環也隨之向外軸向移動而與該固定封環形成互相抵接。In the second embodiment of the present invention, a card type single-axis seal is used, mainly for retaining a fixed seal ring, a second rotating ring, and a second leg and a second protrusion of the retaining ring, as in the foregoing embodiment. The other fixed ring, the first rotating ring, and the first leg and the first protrusion of the retaining ring are subtracted; therefore, when the elastic member pushes the compression ring outward, The outer peripheral portion of the compression ring cooperates with the second protrusion such that the compression ring moves axially between the side of the retaining ring and the second protrusion, and when the compression ring moves axially outward to When the second rotating ring is contacted, the first rotating ring is also moved axially outward to form a mutual abutment with the fixed sealing ring.
本發明第一、二種實施型態的功效在於，由於所述彈性件是定位於壓縮環與保持環之間，再配合所述壓縮環的外周部與第一(第二)突塊相配合，使得所述壓縮環的移動距離會被限制，如此可使各元件不易分離且容易組裝，並且所述壓縮環與靜環被彈性件向外推移與轉動環相抵接，也能藉以降低該本體組內之液體洩漏的機會，另外，於維修替換時，也只需要替換所述固定封環與第一(第二)轉動環，較為簡便，除此之外，第一種實施型態在結構上由於是採用對稱卡匣式雙軸封，所以平衡性會顯得較佳。The first and second embodiments of the present invention are effective in that the elastic member is positioned between the compression ring and the retaining ring, and the outer peripheral portion of the compression ring is matched with the first (second) projection. Therefore, the moving distance of the compression ring is limited, so that the components are not easily separated and easy to assemble, and the compression ring and the static ring are pushed outward by the elastic member to abut against the rotating ring, thereby reducing the body. The opportunity for liquid leakage in the group, in addition, in the maintenance replacement, it is only necessary to replace the fixed sealing ring and the first (second) rotating ring, which is relatively simple, in addition to the first embodiment in the structure Since the symmetrical cassette double-axis seal is used, the balance will be better.

本實施例在該第一轉動環44與該軸套46的環凸肋462之間安裝有一O型環b1，在該第二轉動環45上亦卡設有一O型環b2，在該軸套46的環溝463內亦安裝有一O型環b3，藉由該等O型環b1、b2、b3來填補於軸套46與第一、二轉動環44、45之間的隙縫，以及軸套46與轉動軸5之間的隙縫，以提高較佳的流體防漏效果，此外，該軸套46的環凸肋462也可以供作該O型環b1的支撐座。In this embodiment, an O-ring b1 is mounted between the first rotating ring 44 and the annular rib 462 of the sleeve 46, and an O-ring b2 is also engaged on the second rotating ring 45. An O-ring b3 is also mounted in the annular groove 463 of 46, and the gap between the sleeve 46 and the first and second rotating rings 44, 45 is filled by the O-rings b1, b2, b3, and the sleeve The gap between the 46 and the rotating shaft 5 is used to improve the leakage prevention effect of the fluid. Further, the annular rib 462 of the sleeve 46 can also be used as a support for the O-ring b1.
再一配合參閱圖2、4，該軸套46的攪動件461可以是為軸向成型之連續螺旋型式，例如圖4所示的連續螺旋狀溝槽型式，或是連續螺旋狀突肋型式(此一型態與圖4只是溝槽、突肋直接互換而已，因此不再另外繪示)，藉此設計，當該軸套46轉動時，該攪動件461便可以使機械設備的液體進行翻攪(即該攪動件461是位於製程側A的位置)，而較不易使液體內的雜質沉積於該第一轉動環44與相對應的固定封環3附近。Referring again to Figures 2 and 4, the agitating member 461 of the sleeve 46 may be a continuous helical pattern that is axially formed, such as the continuous helical groove pattern shown in Figure 4, or a continuous helical rib pattern ( This type is only interchangeable with the groove and the protruding rib in FIG. 4, and therefore is not separately shown. By this design, when the sleeve 46 is rotated, the agitating member 461 can turn the liquid of the mechanical device. The agitating (i.e., the agitating member 461 is at the position of the process side A) is less likely to cause impurities in the liquid to deposit in the vicinity of the first rotating ring 44 and the corresponding fixed sealing ring 3.
以上所述為本實施例實際使用的態樣敘述，以下則詳述本實施例對於該保持環41與兩壓縮環42的組裝方式：請參閱圖5～8，首先定義從該軸孔中央軸線C到第一、二突塊414、415的最短距離是定義為D1，從該軸孔中央軸線C到第一、二支腳412、413的最短距離是定義為D2，從該軸孔中央軸線C到切裁部422的最短距離是定義為D3，而且D3≦D1＜D2。再者，該二壓縮環42是由所述之彈性件43的兩端共同頂制，於安裝時，是先使一壓縮環42的切裁部422與保持環41之第一支腳412對齊，並壓入該壓縮環42於保持環41內，再旋轉該壓縮環42使其與第一支腳412錯開，此時先置入該等彈性件43後再置入另一壓縮環42，並使該另一壓縮環42的切裁部422與該保持環41之第二支腳413對齊，並壓入該另一壓縮環42於保持環41內，再旋轉該另一壓縮環42使其與保持環41之第二支腳413錯開，即可完成此安裝動件。當然，該保持環41、二壓縮環42，及所述之彈性件43於安裝後，只需如圖7、8所示的正確位置型態，則並不侷限於前述之安裝順序。The above is a description of the actual use of the embodiment. The following describes the assembly of the retaining ring 41 and the two compression rings 42 in this embodiment: Referring to FIGS. 5-8, the central axis from the axial hole is first defined. The shortest distance from C to the first and second protrusions 414, 415 is defined as D1, and the shortest distance from the central axis C of the shaft hole to the first and second legs 412, 413 is defined as D2 from the central axis of the shaft hole The shortest distance from C to the cut portion 422 is defined as D3, and D3 ≦ D1 < D2. Furthermore, the two compression rings 42 are co-made by the two ends of the elastic member 43. When mounting, the cutting portion 422 of a compression ring 42 is aligned with the first leg 412 of the retaining ring 41. And pressing the compression ring 42 into the retaining ring 41, and then rotating the compression ring 42 to be offset from the first leg 412. At this time, the elastic members 43 are placed first, and then the other compression ring 42 is placed. And the cutting portion 422 of the other compression ring 42 is aligned with the second leg 413 of the retaining ring 41, and the other compression ring 42 is pressed into the retaining ring 41, and the other compression ring 42 is rotated. This mounting member can be completed by being offset from the second leg 413 of the retaining ring 41. Of course, the retaining ring 41, the two compression rings 42, and the elastic member 43 need only be in the correct position as shown in FIGS. 7 and 8 after installation, and are not limited to the aforementioned mounting sequence.
由於，從該軸孔中央軸線C到外周部421的最短距離D4，大於從該軸孔中央軸線C到第一、二突塊414、415的最短距離D1(即D1＜D4)，小於或等於從該軸孔中央軸線C到第一、二支腳412、413的最短距離D2(即D4≦D2)，因此，該二壓縮環42就會被限位於該保持環41之兩側面與第一、二突塊414、415之間，而所述彈性件43的兩端始終會分別觸抵該二壓縮環42，且所述彈性件43被第一、二突塊414、415侷限活動距離而不易散落，藉使該二壓縮環42、保持環41、彈性件43共同形成一個模組化的設計，而易於與其他構件繼續安裝。Since the shortest distance D4 from the central axis C of the shaft hole to the outer peripheral portion 421 is greater than the shortest distance D1 from the central axis C of the shaft hole to the first and second projections 414, 415 (i.e., D1 < D4), less than or equal to From the central axis C of the shaft hole to the shortest distance D2 of the first and second legs 412, 413 (ie, D4 ≦ D2), therefore, the two compression rings 42 are limited to the two sides of the retaining ring 41 and the first Between the two protrusions 414, 415, the two ends of the elastic member 43 always touch the two compression rings 42, respectively, and the elastic member 43 is limited by the first and second protrusions 414, 415 The two compression rings 42, the retaining ring 41, and the elastic member 43 together form a modular design, and are easy to be installed with other components.
回到圖2所示，詳細地說，當上述模組安裝於該本體組2內，由於所述彈性件43是將該二壓縮環42向外推抵，並藉由該二壓縮環42的外周部421與第一、二突塊414、415相配合，使得其中一壓縮環42是在該保持環41的側面與第一突塊414之間軸向移動，另一壓縮環42則是在該保持環41的另一側面與第二突塊415之間軸向移動，當該二壓縮環42向外軸向移動至接觸所述第一、二轉動環44、45時，便會連動所述第一、二轉動環44、45也隨之向外軸向移動而與該二固定封環3形成互相接觸，因此，可有效避免該第一、二轉動環44、45與該二固定封環3之間產生縫隙，降低該本體組2內之液體洩漏的機會。Referring to FIG. 2, in detail, when the module is installed in the body group 2, the elastic member 43 pushes the two compression rings 42 outward, and the two compression rings 42 are The outer peripheral portion 421 cooperates with the first and second projections 414, 415 such that one of the compression rings 42 moves axially between the side of the retaining ring 41 and the first projection 414, and the other compression ring 42 is The other side of the retaining ring 41 moves axially between the second projection 415, and when the two compression rings 42 are axially moved outward to contact the first and second rotating rings 44, 45, the linkage is activated. The first and second rotating rings 44, 45 are also axially moved outwardly to form a mutual contact with the two fixed sealing rings 3, thereby effectively avoiding the first and second rotating rings 44, 45 and the two fixed seals. A gap is created between the rings 3, reducing the chance of liquid leakage within the body set 2.
根據上述內容，由於所述彈性件43是各別設置於該保持環41的容置孔416中，所以可以很容易地定位於壓縮環42與保持環41之間，再配合該二壓縮環42的外周部421與第一、二突塊414、415相配合，使得該二壓縮環42的移動距離會被限制，如此可使各元件不易分離且容易組裝，另外，於替換時也只需要替換該二固定封環3與第一、二轉動環44、45而較為簡便，再者，結構上是對稱雙匣形式，其平衡性較佳。According to the above, since the elastic members 43 are respectively disposed in the receiving holes 416 of the retaining ring 41, they can be easily positioned between the compression ring 42 and the retaining ring 41, and then cooperate with the two compression rings 42. The outer peripheral portion 421 cooperates with the first and second protrusions 414, 415, so that the moving distance of the two compression rings 42 is limited, so that the components can be easily separated and assembled easily, and only need to be replaced in the replacement. The two fixed sealing rings 3 and the first and second rotating rings 44, 45 are relatively simple, and further, the structure is a symmetric double-twisted form, and the balance is better.
另外，當第一、二凹槽444、454的數量是相對應地大於第一、二支腳412、413的數量時，本實施例中至少有一部分未使用的第一、二凹槽444、454是相對於第一、二支腳412、413形成傾斜，藉此對該外殼2內的流體形成渦輪式的導引作用。In addition, when the number of the first and second grooves 444, 454 is correspondingly greater than the number of the first and second legs 412, 413, at least a portion of the unused first and second grooves 444, The 454 is inclined relative to the first and second legs 412, 413, thereby forming a turbine-like guiding effect on the fluid in the outer casing 2.
而本實施例中，該第一轉動環44並未形成有凹槽的設計，該保持環41之第一支腳412是直接觸抵到該第一轉動環44的環凸緣443上，當然該第一轉動環44也可以採用類似該第二轉動環45的凹槽454結構設計，使得該第一、二轉動環44、45可以為同一物件，易於備料，所以不應以本實施例的說明為限。In this embodiment, the first rotating ring 44 is not formed with a groove. The first leg 412 of the retaining ring 41 is in direct contact with the ring flange 443 of the first rotating ring 44. The first rotating ring 44 can also be designed with a groove 454 similar to the second rotating ring 45, so that the first and second rotating rings 44, 45 can be the same object, which is easy to prepare, so the present embodiment should not be used. The description is limited.
此外，本實施例更包含一呈環狀並與該軸孔22同軸設置的限位件47，該限位件47是卡固於該本體組2之外本體21內側面，並且鄰近於被該第一轉動環44所抵觸的固定封環3，而且該限位件47亦具有多數個貫孔471，藉使該本體組2內的流體既可以經由所述貫孔471而流入該本體組2與固定封環3之間作冷卻，而且也能防止該固定封環3因產生過大的軸向移動造成過度磨耗，而能有效維持密封效果，至於在本實施例中，是採用C型扣作為該限位件47。In addition, the embodiment further includes a limiting member 47 that is annular and coaxial with the shaft hole 22, and the limiting member 47 is fastened to the inner side of the body 21 outside the body group 2, and adjacent to the The fixed ring 3 is in contact with the first rotating ring 44, and the limiting member 47 also has a plurality of through holes 471, so that the fluid in the body group 2 can flow into the body group 2 through the through holes 471. Cooling is provided between the fixed seal ring 3 and the fixed seal ring 3, and the seal ring 3 is prevented from being excessively worn due to excessive axial movement, and the sealing effect can be effectively maintained. In the present embodiment, the C-type buckle is used as the seal. The limiting member 47.
一併參閱圖2、3，另外為了使流體對於該本體組2與轉動單元4的熱交換效率更為提高，本實施例之軸封裝置1更包含一導流件48，該導流件48是設置於該本體組2之外本體21內側面且介於該外本體21與轉動單元4之間，該導流件48是呈環狀並與該軸孔22同軸設置，該導流件48具有一用來容置該轉動單元4各個細部構件的容置空間481，及一連通內、外周面並與該流入口23、流出口24皆形成流通的流道483，其中，該O型環b4是用來封擋該本體組2與導流件48之間的縫隙以避免流體洩漏。Referring to FIGS. 2 and 3, in addition, in order to improve the heat exchange efficiency of the fluid group to the rotating unit 4, the shaft sealing device 1 of the present embodiment further includes a flow guiding member 48, and the flow guiding member 48 Is disposed on the inner side of the body 21 outside the body group 2 and between the outer body 21 and the rotating unit 4, the flow guiding member 48 is annular and coaxially disposed with the shaft hole 22, the flow guiding member 48 The accommodating space 481 for accommodating the various components of the rotating unit 4, and a flow channel 483 communicating with the inner and outer peripheral surfaces and forming a flow path with the inflow port 23 and the outflow port 24, wherein the O-ring B4 is used to seal the gap between the body group 2 and the flow guiding member 48 to avoid fluid leakage.
再一併參閱圖2、9，該本體組2的流入口23與流出口24是在同一徑向平面相較於該軸孔22形成徑向延伸，而該流道483具有至少一導引面484(本實施例為二導引面484)，可為入口或出口，其中，一導引面484與該流入口23相鄰近且形成傾斜，另一導引面484則與該流出口24相鄰近且形成傾斜，因此，流體會自該流入口23進入時，會被鄰近該流入口23的導引面484所導引，而沿著該軸孔22的周緣流動，再被鄰近該流出口24的導引面484所導引而自該流出口24離開，使得流體會有方向性地、順暢地對該轉動單元4進行熱交換作用，而較不易有擾流或存積於該流道483的情況發生，有效提高整體的熱交換效率。Referring again to FIGS. 2 and 9, the inflow port 23 and the outflow port 24 of the body group 2 form a radial extension in the same radial plane as the shaft hole 22, and the flow channel 483 has at least one guiding surface. 484 (the second guiding surface 484 in this embodiment) may be an inlet or an outlet, wherein a guiding surface 484 is adjacent to the inlet 23 and inclined, and the other guiding surface 484 is opposite to the outlet 24 Adjacent and inclined, the fluid will be guided by the guiding surface 484 adjacent to the inflow opening 23, flow along the circumference of the shaft hole 22, and be adjacent to the outflow port. The guiding surface 484 of the 24 is guided away from the outflow port 24, so that the fluid can exchange heat to the rotating unit 4 in a directional and smooth manner, and is less prone to turbulence or accumulation in the flow path. The situation of 483 occurs, effectively improving the overall heat exchange efficiency.
參閱圖10，本發明軸封裝置1的第二較佳實施例，大致類似於前述圖2所示之第一較佳實施例，不同的地方在於：本實施例是採用單匣形式，主要是保留一個固定封環3、一個壓縮環42、第二轉動環45，以及該保持環41的第二支腳413與第二突塊415，並且該保持環41的容置孔416為盲孔形式，而每一彈性件43的兩端是分別對應觸抵於該壓縮環42及保持環41，至於前述圖2所示之實施型態中的另一個固定封環3、另一個壓縮環42、第一轉動環44，以及該保持環41的第一支腳412與第一突塊414則予以減除；因此，當所述彈性件43將該壓縮環42向外推抵時，便會藉由該壓縮環42與第二突塊415相配合，使得該壓縮環42是在該保持環41的側面與第二突塊415之間軸向移動，當該壓縮環42向外軸向移動至接觸該第二轉動環45時，便會連動該第二轉動環45也隨之向外軸向移動而與該 固定封環3形成互相接觸。Referring to FIG. 10, a second preferred embodiment of the shaft sealing device 1 of the present invention is substantially similar to the first preferred embodiment shown in FIG. 2, except that the embodiment is in the form of a single turn, mainly A fixed seal ring 3, a compression ring 42, a second rotating ring 45, and a second leg 413 and a second protrusion 415 of the retaining ring 41 are retained, and the receiving hole 416 of the retaining ring 41 is in the form of a blind hole. The two ends of each of the elastic members 43 are respectively corresponding to the compression ring 42 and the retaining ring 41, and the other fixed ring 3 and the other compression ring 42 of the embodiment shown in FIG. 2 are The first rotating ring 44, and the first leg 412 and the first protrusion 414 of the retaining ring 41 are then subtracted; therefore, when the elastic member 43 pushes the compression ring 42 outward, it will borrow The compression ring 42 cooperates with the second projection 415 such that the compression ring 42 moves axially between the side of the retaining ring 41 and the second projection 415, and the compression ring 42 moves axially outward to When the second rotating ring 45 is contacted, the second rotating ring 45 is linked to move outwardly and axially The fixed seal rings 3 are brought into contact with each other.
藉此設計，由於所述彈性件43是定位於壓縮環42與保持環41之間，再配合該壓縮環42與第二突塊415相配合，使得該壓縮環42的移動距離會被限制，如此可使各元件不易分離且容易組裝，並且該壓縮環42被彈性件43向外推移至與該固定封環3形成持續接觸，也能藉以降低液體洩漏的機會，另外，於替換時也只需要替換該固定封環3與第二轉動環45，較為簡便。With this design, since the elastic member 43 is positioned between the compression ring 42 and the retaining ring 41, and the compression ring 42 is engaged with the second protrusion 415, the moving distance of the compression ring 42 is limited. In this way, the components can be easily separated and assembled easily, and the compression ring 42 is pushed outward by the elastic member 43 to form continuous contact with the fixed sealing ring 3, thereby also reducing the chance of liquid leakage, and in addition, only replacing It is relatively simple to replace the fixed seal ring 3 and the second rotating ring 45.
參閱圖11，本發明軸封裝置1的第三較佳實施例，大致類似於前述圖3所示之第一較佳實施例，不同的地方在於：該保持環41的主環部411具有一輔導流組417，而該輔導流組417具有多數條切刀418(本實施例是以多數條為例，只有一條也可以)，以協助液體產生特定方向的流動，而同樣地提高整體的熱交換效率。Referring to Figure 11, a third preferred embodiment of the shaft sealing device 1 of the present invention is substantially similar to the first preferred embodiment shown in Figure 3, except that the main ring portion 411 of the retaining ring 41 has a The tutoring stream group 417 is provided, and the tutoring stream group 417 has a plurality of cutters 418 (in this embodiment, a plurality of strips are exemplified, only one may be used) to assist the liquid to flow in a specific direction, and the overall heat is similarly improved. Exchange efficiency.
參閱圖12、13，本發明軸封裝置1的第四較佳實施例，大致類似於前述第一較佳實施例，不同的地方在於：該流入口23與流出口24是在不同徑向平面相較於該軸孔22形成徑向延伸，該導流件48是呈管狀並與該軸孔22同軸設置且鄰近該流入口23，該導流件48的流道483則是與該流出口24並排連通，而且該導流件48具有一形成有多數個徑向溝槽486的第一端面485(此一型態通常稱為冠狀型式)，及一徑向突出狀的第二端面487，該第一端面485是鄰近該第一轉動環44，該第二端面487則是與該本體組2之外本體21內側面互相連接。Referring to Figures 12 and 13, a fourth preferred embodiment of the shaft sealing device 1 of the present invention is substantially similar to the first preferred embodiment described above, except that the inflow port 23 and the outflow port 24 are in different radial planes. The flow guiding member 48 is formed in a tubular shape and is coaxial with the shaft hole 22 and adjacent to the flow inlet 23. The flow path 483 of the flow guiding member 48 is connected to the outflow port. 24 is in parallel communication, and the flow guiding member 48 has a first end surface 485 formed with a plurality of radial grooves 486 (this type is generally referred to as a crown type), and a radially protruding second end surface 487. The first end surface 485 is adjacent to the first rotating ring 44, and the second end surface 487 is interconnected with the inner side surface of the body 21 outside the body group 2.
據此，該導流件48能夠將流體平滑地由該流入口23進入，並經由各個徑向溝槽486，而直接對第一轉動環44與鄰近的相對應固定封環3產生冷卻或加熱作用。Accordingly, the flow guiding member 48 can smoothly enter the fluid from the inflow port 23 and directly cool or heat the first rotating ring 44 and the adjacent corresponding fixed sealing ring 3 via the respective radial grooves 486. effect.
該第一端面485除了可以設計為上述之冠狀型式，另外也可以設計為環狀型式，同樣都可以將流體平滑引導以達到冷卻或加熱的效果，所以不應以本實施例之說明為限。The first end surface 485 can be designed as the above-mentioned crown type, or can be designed as an annular type, and the fluid can be smoothly guided to achieve the cooling or heating effect, so it should not be limited to the description of the embodiment.
除此之外，本發明軸封裝置1也可以在該轉動軸5上同時串聯套設有多數個，也就是說，可以是如圖2所示之對稱卡匣式雙軸封予以同時串聯，或是如圖10所示之卡匣式單軸封予以同時串聯，此種安裝方式能夠是因應實際需求加以改變，所以也不應以本實施例之說明為限。In addition, the shaft sealing device 1 of the present invention can also be arranged in series on the rotating shaft 5 at the same time, that is to say, the symmetrical cassette double-axis seals as shown in FIG. 2 can be simultaneously connected in series. Or the card type single-axis seals shown in FIG. 10 are connected in series at the same time, and the installation manner can be changed according to actual needs, and therefore should not be limited to the description of the embodiment.
綜上所述，本發明軸封裝置1，主要藉由該保持環41與壓縮環42的獨特造型設計，而使該軸封裝置1在組裝或維修時都不易讓所述彈性件43分離掉落，進而達到容易組裝、各元件不易分離的優點，並且該壓縮環42被彈性件43向外推移至與該固定封環3形成持續接觸，也能藉以降低液體洩漏的機會，再者，倘若結構上是採用圖2所示之對稱雙匣形式，平衡性也顯得較佳而能應用於更多特殊場合，所以確實能達到本發明之目的。In summary, the shaft sealing device 1 of the present invention mainly makes the shaft sealing device 1 difficult to separate the elastic member 43 during assembly or maintenance by the unique design of the retaining ring 41 and the compression ring 42.
