[發明所欲解決之問題][The problem that the invention wants to solve]
然而，在專利文獻1所揭示之密封中，為了在避免朝外殼之方向彎折之凸緣與外殼之接觸下收容凸緣而確保充分之空間，故存在外殼之設計自由度受限制之問題。However, in the seal disclosed in Patent Document 1, in order to secure a sufficient space by accommodating the flange in contact with the flange which is bent in the direction of the outer casing, there is a problem that the degree of freedom in designing the outer casing is limited.
本發明之目的在於提供一種具有設計自由度為高之密封機構的裝置。
[解決問題之技術手段]It is an object of the present invention to provide a device having a sealing mechanism with a high degree of freedom of design.
[Technical means to solve the problem]
在本發明之一實施形態之裝置中，該裝置具有：軸構件；殼體；其收容該軸構件之至少一部分；及密封機構，其將該軸構件與該殼體之間密封；且該密封機構具有：甩油環，其設置於前述軸構件之外周面；及密封構件，其設置於前述殼體與該甩油環之間；前述甩油環具有：筒狀部；及凸緣部，其自該筒狀部觀察位於前述軸構件之徑向內側；供設置該筒狀部之位置處之該軸構件的外徑與供設置前述凸緣部之位置處之前述軸構件之外徑形成為相同。In an apparatus according to an embodiment of the present invention, the apparatus has: a shaft member; a housing; housing at least a portion of the shaft member; and a sealing mechanism that seals the shaft member from the housing; and the seal The mechanism has an oil slinger disposed on an outer circumferential surface of the shaft member, and a sealing member disposed between the housing and the oil slinger; the oil slinger having a cylindrical portion; and a flange portion It is located on a radially inner side of the shaft member as viewed from the cylindrical portion; an outer diameter of the shaft member at a position where the cylindrical portion is provided and an outer diameter of the shaft member at a position where the flange portion is provided For the same.
根據上述構成，由於藉由供設置該筒狀部之位置之該軸構件之外徑與供設置前述凸緣部之位置之前述軸構件之外徑形成為相同，而在甩油環朝軸構件之安裝時，無須變更軸構件之外徑尺寸，故可確保軸構件之設計自由度。According to the above configuration, since the outer diameter of the shaft member at the position where the cylindrical portion is provided is the same as the outer diameter of the shaft member at the position where the flange portion is provided, the oil slinger is directed toward the shaft member. When mounting, it is not necessary to change the outer diameter of the shaft member, so the design freedom of the shaft member can be ensured.
在本發明之一實施形態之裝置中，在軸構件設置緊固該軸構件之螺栓，該螺栓之中心位置配置於與前述軸構件之外周面接近之位置。In the apparatus according to the embodiment of the present invention, the shaft member is provided with a bolt for fastening the shaft member, and the center position of the bolt is disposed at a position close to the outer peripheral surface of the shaft member.
由於供設置筒狀部之位置之該軸構件之外徑與供設置前述凸緣部之位置之前述軸構件之外徑形成為相同，故除在甩油環朝軸構件之安裝時無須變更軸構件之外徑尺寸外，根據上述構成，還可藉由將緊固軸構件之螺栓之中心位置配置於更接近軸構件之外周面，而增長距軸構件之中心位置之距離，藉此可提高軸緊固力。Since the outer diameter of the shaft member for providing the position of the cylindrical portion is formed to be the same as the outer diameter of the shaft member for providing the flange portion, the shaft is not required to be changed when the oil sling is mounted toward the shaft member. In addition to the outer diameter of the member, according to the above configuration, it is also possible to increase the distance from the center position of the shaft member by arranging the center position of the bolt of the fastening shaft member closer to the outer peripheral surface of the shaft member. Shaft tightening force.
在本發明之一實施形態之裝置中，前述軸構件之前述螺栓之中心位置配置於在將前述螺栓螺合於前述軸構件時維持前述軸構件之外周形狀之位置，且為最靠近前述軸構件之外周面之位置。In the apparatus according to the embodiment of the present invention, the center position of the bolt of the shaft member is disposed at a position to maintain the outer peripheral shape of the shaft member when the bolt is screwed to the shaft member, and is closest to the shaft member. The position of the outer circumference.
由於供設置筒狀部之位置之該軸構件之外徑與供設置前述凸緣部之位置之前述軸構件之外徑形成為相同，故除在甩油環朝軸構件之安裝時無須變更軸構件之外徑尺寸外，根據上述構成，還可藉由將緊固軸構件之螺栓之中心位置配置於更靠近軸構件之外周面，而增長距軸構件之中心位置之距離，從而可增大朝被緊固於軸構件之構件的傳遞力矩。Since the outer diameter of the shaft member for providing the position of the cylindrical portion is formed to be the same as the outer diameter of the shaft member for providing the flange portion, the shaft is not required to be changed when the oil sling is mounted toward the shaft member. In addition to the outer diameter of the member, according to the above configuration, the center position of the bolt of the fastening shaft member can be increased closer to the outer peripheral surface of the shaft member, and the distance from the center position of the shaft member can be increased, thereby increasing The transmitted torque toward the member that is fastened to the shaft member.
又，在本發明之一實施形態之裝置中，前述軸構件之前述螺栓之中心位置配置於距前述軸構件之外周面3 mm-10 mm之範圍內之位置。Further, in the apparatus according to the embodiment of the present invention, the center position of the bolt of the shaft member is disposed at a position within a range of 3 mm to 10 mm from the outer circumferential surface of the shaft member.
由於供設置筒狀部之位置之該軸構件之外徑與供設置前述凸緣部之位置之前述軸構件之外徑形成為相同，故除在甩油環朝軸構件之安裝時無須變更軸構件之外徑尺寸外，根據上述構成，還可藉由緊固軸構件之螺栓之中心位置配置於距軸構件之外周面3 mm-10 mm之範圍內，而增長距軸構件之中心位置之距離，藉此可有助於提高軸緊固力及朝被緊固於軸構件之構件的傳遞力矩。Since the outer diameter of the shaft member for providing the position of the cylindrical portion is formed to be the same as the outer diameter of the shaft member for providing the flange portion, the shaft is not required to be changed when the oil sling is mounted toward the shaft member. In addition to the outer diameter of the member, according to the above configuration, the center position of the bolt for fastening the shaft member may be disposed within a range of 3 mm to 10 mm from the outer peripheral surface of the shaft member, and the center position of the shaft member may be increased. The distance can thereby contribute to an increase in the shaft fastening force and a transmission torque to the member fastened to the shaft member.
在本發明之一實施形態之裝置中，在前述筒狀部與前述軸構件之間具有接著層，前述凸緣部朝前述軸構件之徑向內側延伸之長度形成為前述接著層之厚度以下。又，在本發明之一實施形態之裝置中，在前述凸緣部朝前述軸構件之徑向內側延伸之長度小於前述接著層之厚度時，在前述軸構件與前述凸緣部之間形成接著層。In the apparatus according to the embodiment of the present invention, an intermediate layer is provided between the tubular portion and the shaft member, and a length of the flange portion extending toward a radially inner side of the shaft member is formed to be equal to or less than a thickness of the adhesive layer. Further, in the apparatus according to the embodiment of the present invention, when the length of the flange portion extending inward in the radial direction inner side of the shaft member is smaller than the thickness of the adhesive layer, a formation is formed between the shaft member and the flange portion. Floor.
根據上述構成，由於藉由凸緣部自筒狀部觀察位於軸構件之徑向內側而不會增加密封機構之外徑尺寸，故不僅可使收容軸構件之至少一部分之殼體小型化，還可維持供安裝甩油環之位置之軸構件之外徑，且追求利用凸緣部提高甩油環之強度。According to the above configuration, since the flange portion is located radially inward of the shaft member from the tubular portion and does not increase the outer diameter of the sealing mechanism, it is possible to reduce not only the housing of at least a part of the housing shaft member but also the housing. The outer diameter of the shaft member for mounting the slinger ring can be maintained, and the use of the flange portion to improve the strength of the slinger ring is sought.
本發明之上述一實施形態之裝置之密封機構可較佳地應用於要求小型化之各種裝置。

其次，本發明之一實施形態之密封機構1包含甩油環2及密封構件3。甩油環2具有圓筒狀之筒狀部11、及自該筒狀部11觀察位於軸構件4之徑向內側之凸緣部12。甩油環2可包含筒狀部11及凸緣部12以外之構成構件，亦可由筒狀部11及凸緣部12構成。Next, the sealing mechanism 1 according to an embodiment of the present invention includes an oil slinger 2 and a sealing member 3. The oil slinger 2 has a cylindrical tubular portion 11 and a flange portion 12 located radially inward of the shaft member 4 as viewed from the tubular portion 11. The oil slinger 2 may include a structural member other than the tubular portion 11 and the flange portion 12, and may be composed of the tubular portion 11 and the flange portion 12.
該甩油環2之筒狀部11可至少一部分形成為筒狀，亦可整體構成為筒狀。筒狀部11之一端或兩端可經部分倒角。The tubular portion 11 of the oil slinger 2 may be formed in a tubular shape at least in part, or may be formed in a tubular shape as a whole. One or both ends of the cylindrical portion 11 may be partially chamfered.
本發明之一實施形態之凸緣部12自筒狀部11之一端或一部分朝軸構件4之徑向內側延伸。若在筒狀部11與凸緣部12之間介置其他之構成構件，該凸緣部12構成為自該其他之構成構件之一端或一部分朝軸構件4之徑向內側延伸。凸緣部12可延伸直至與軸構件4之外周面14接觸，亦可構成為延伸至其近前。The flange portion 12 of one embodiment of the present invention extends from one end or a portion of the tubular portion 11 toward the radially inner side of the shaft member 4. When another constituent member is interposed between the tubular portion 11 and the flange portion 12, the flange portion 12 is configured to extend from one end or a portion of the other constituent member toward the radially inner side of the shaft member 4. The flange portion 12 may extend until it comes into contact with the outer peripheral surface 14 of the shaft member 4, or may be configured to extend to the front thereof.
本發明之一實施形態之筒狀部11具有內周面21、及與該內周面21為相反側之外周面20。筒狀部11之內周面21係由接著層AHL接著於軸構件4之外周面14。如此，軸構件4之外周面14由筒狀部11包圍周圍。亦可另行使用決定將甩油環2安裝於軸構件4之位置的治具(未圖示)。亦可取代該接著層AHL，而將具有密封性之橡膠構件介置於筒狀部11之內周面21與軸構件4之外周面14之間，亦可介置其他之構件。The tubular portion 11 according to an embodiment of the present invention has an inner circumferential surface 21 and an outer circumferential surface 20 opposite to the inner circumferential surface 21. The inner peripheral surface 21 of the tubular portion 11 is followed by the outer layer 14 on the outer peripheral surface 14 of the shaft member 4. In this manner, the outer peripheral surface 14 of the shaft member 4 is surrounded by the tubular portion 11. A jig (not shown) that determines the position at which the oil slinger 2 is attached to the shaft member 4 may be separately used. Instead of the adhesive layer AHL, a rubber member having a sealing property may be interposed between the inner circumferential surface 21 of the tubular portion 11 and the outer circumferential surface 14 of the shaft member 4, and other members may be interposed.
在圖示之例中，凸緣部12的自軸構件4之徑向觀察自筒狀部11突出之長度構成為與接著層AHL之厚度相同或小於其。凸緣部12自軸構件4之徑向觀察之自筒狀部11突出之長度若小於接著層AHL之厚度，亦可構成為在凸緣部之端面22與軸構件4之外周面14之間形成接著層AHL。In the illustrated example, the length of the flange portion 12 protruding from the tubular portion 11 from the radial direction of the shaft member 4 is configured to be the same as or smaller than the thickness of the adhesive layer AHL. The length of the flange portion 12 protruding from the tubular portion 11 as viewed in the radial direction of the shaft member 4 may be configured to be between the end surface 22 of the flange portion and the outer peripheral surface 14 of the shaft member 4, if the length of the protrusion from the tubular portion 11 is smaller than the thickness of the adhesive layer AHL. An adhesive layer AHL is formed.
本發明之一實施形態之軸構件4可形成為供設置筒狀部11之位置處之該軸構件4的外徑與供設置凸緣部12之位置處之前述軸構件4之外徑相同。此外，應瞭解由於此處言及之相同亦包含尺寸誤差等製造時不可避免之誤差的範圍，並非一定意指完全相同者，亦包含實質上相同之情形。The shaft member 4 according to an embodiment of the present invention can be formed such that the outer diameter of the shaft member 4 at the position where the cylindrical portion 11 is provided is the same as the outer diameter of the shaft member 4 at the position where the flange portion 12 is provided. In addition, it should be understood that the scope of the error that is unavoidable at the time of manufacture, such as a dimensional error, is also included in the context of the same, and does not necessarily mean that they are identical and substantially the same.
在本發明之一實施形態之軸構件4設置將該軸構件4與其他之構成構件(未特別圖示)緊固的螺栓(未特別圖示)之螺紋孔30，該螺栓之中心位置100(或螺紋孔30之中心位置100)配置於與軸構件4之外周面14接近之位置。The shaft member 4 according to an embodiment of the present invention is provided with a threaded hole 30 of a bolt (not shown) for fastening the shaft member 4 to another structural member (not shown), and the center position of the bolt is 100 ( Or the center position 100) of the screw hole 30 is disposed at a position close to the outer peripheral surface 14 of the shaft member 4.
供設置該筒狀部之位置處之該軸構件之外徑與供設置前述凸緣部之位置處之前述軸構件之外徑形成為相同。亦即，在將甩油環朝軸構件安裝時，未變更軸構件之外徑尺寸。又，藉由將緊固軸構件之螺栓之中心位置配置於更靠近軸構件之外周面，可增長距軸構件之中心位置之距離，藉此提高軸緊固力。The outer diameter of the shaft member at the position where the cylindrical portion is provided is formed to be the same as the outer diameter of the shaft member at the position where the flange portion is provided. That is, the outer diameter of the shaft member is not changed when the oil slinger is attached to the shaft member. Further, by arranging the center position of the bolt of the fastening shaft member closer to the outer circumferential surface of the shaft member, the distance from the center position of the shaft member can be increased, thereby increasing the shaft fastening force.
本發明之一實施形態之軸構件4之螺栓之中心位置配置於在將該螺栓螺合於該軸構件4時維持該軸構件4之外周形狀之位置，且為最靠近軸構件4之外周面之位置。藉此，可增大朝被緊固於軸構件之構件的傳遞力矩。The center position of the bolt of the shaft member 4 according to the embodiment of the present invention is disposed at a position where the outer peripheral shape of the shaft member 4 is maintained when the bolt is screwed to the shaft member 4, and is closest to the outer peripheral surface of the shaft member 4. The location. Thereby, the transmission torque to the member fastened to the shaft member can be increased.
本發明之一實施形態之軸構件4之螺栓的中心位置配置於距軸構件4之外周面14為3 mm-10 mm之範圍內之位置。藉此，可增長距軸構件之中心位置之距離，從而可有助於提高軸緊固力或朝被緊固於軸構件之構件的傳遞力矩。The center position of the bolt of the shaft member 4 according to the embodiment of the present invention is disposed at a position within a range of 3 mm to 10 mm from the outer peripheral surface 14 of the shaft member 4. Thereby, the distance from the center position of the shaft member can be increased, thereby contributing to an increase in the shaft fastening force or a transmission torque toward the member fastened to the shaft member.
如此，本發明之一實施形態之軸構件4無須為了載置甩油環2而採用特殊的設計，可確保軸構件4之設計自由度。又，藉由殼體5之上述之甩油環之構造，可在凸緣不干涉殼體下確保殼體之設計自由度。再者，藉由在凸緣之外周部配置密封，可縮短密封機構之輸出軸方向長度。如此，可使密封機構1之尺寸小型化。藉此，可確保經密封構築之裝置1之構成零件的設計自由度。又，軸構件4與殼體5之間之空間亦可為了配置各種零件而有效地利用。As described above, the shaft member 4 according to the embodiment of the present invention does not need to have a special design for placing the oil slinger 2, and the degree of freedom in designing the shaft member 4 can be ensured. Moreover, by the above-described structure of the slinger ring of the casing 5, the degree of freedom in designing the casing can be ensured without the flange interfering with the casing. Further, by arranging the seal on the outer periphery of the flange, the length in the output shaft direction of the sealing mechanism can be shortened. In this way, the size of the sealing mechanism 1 can be reduced. Thereby, the degree of freedom in designing the components of the device 1 that is sealed and constructed can be ensured. Further, the space between the shaft member 4 and the casing 5 can be effectively utilized for arranging various components.
其次，本發明之一實施形態之密封構件3係具有抵接於殼體5之內周面15之外周面23的環狀之構件。密封構件3形成為包圍軸構件4之旋轉軸周圍。密封構件3包含：主環部24、環狀之主唇25、環狀之防塵唇26、及彈簧環27。Next, the sealing member 3 according to an embodiment of the present invention has an annular member that abuts against the outer peripheral surface 23 of the inner peripheral surface 15 of the casing 5. The sealing member 3 is formed to surround the circumference of the rotating shaft of the shaft member 4. The sealing member 3 includes a main ring portion 24, an annular main lip 25, an annular dust lip 26, and a spring ring 27.
此外，在圖1所示之例中，與密封構件3相鄰地，將另一密封構件6以進一步包圍軸構件4之旋轉軸周圍之方式配置，且自軸構件4之旋轉軸方向觀察配置於外側(外部空間側)，但可另行配置追加之密封構件，亦可構成為不配置另一密封構件6及追加之密封構件任一者。另一密封構件6由於與密封構件3對照地構成，故省略詳細之說明。Further, in the example shown in FIG. 1, adjacent to the sealing member 3, the other sealing member 6 is disposed so as to further surround the rotation axis of the shaft member 4, and is disposed from the direction of the rotation axis of the shaft member 4. The outer side (outer space side) may be separately provided with an additional sealing member, or may be configured such that neither of the other sealing member 6 nor the additional sealing member is disposed. Since the other sealing member 6 is configured in comparison with the sealing member 3, detailed description thereof will be omitted.
本發明之一實施形態之密封構件3之主環部24包含第1部分241及第2部分242。該第1部分241形成作為具有與軸構件4之旋轉軸大致一致之中心軸的圓筒狀之部位。該第1部分241之外周面之一部分或整體抵接於殼體5之內周面15。另一方面，第2部分242自第1部分241之端部彎曲，形成為朝向軸構件4之徑向內側突出之環狀之部位。該第2部分242包含與筒狀部11之外周面20對向之內周端243。防塵唇26及主唇25連接於內周端243。The main ring portion 24 of the sealing member 3 according to the embodiment of the present invention includes the first portion 241 and the second portion 242. The first portion 241 is formed as a cylindrical portion having a central axis that substantially coincides with the rotation axis of the shaft member 4. One or the entire outer peripheral surface of the first portion 241 abuts against the inner circumferential surface 15 of the casing 5. On the other hand, the second portion 242 is bent from the end portion of the first portion 241 and formed as an annular portion that protrudes inward in the radial direction of the shaft member 4. The second portion 242 includes an inner peripheral end 243 that faces the outer peripheral surface 20 of the tubular portion 11. The dust lip 26 and the main lip 25 are connected to the inner peripheral end 243.
本發明之一實施形態之防塵唇26自主環部24之內周端243朝向外部空間及軸構件4之徑向內側傾斜地突出。防塵唇26用於防止在外部空間浮游之塵埃等異物侵入內部空間。The inner peripheral end 243 of the autonomous lip portion 24 of the dust lip 26 according to the embodiment of the present invention protrudes obliquely toward the outer space and the radially inner side of the shaft member 4. The dust lip 26 is for preventing foreign matter such as dust floating in the external space from entering the internal space.
該防塵唇26之前端抵接於筒狀部11之外周面20。在軸構件4及殼體5中至少一者旋轉之期間，防塵唇26之前端會與甩油環2之筒狀部11摩擦，但由於甩油環2由與軸構件4相比耐磨耗性更優異之材料形成，故即便在防塵唇26對筒狀部11滑接之狀態持續之情形下，甩油環2也幾乎不會磨耗。The front end of the dust lip 26 abuts against the outer peripheral surface 20 of the tubular portion 11. During the rotation of at least one of the shaft member 4 and the housing 5, the front end of the dust lip 26 rubs against the cylindrical portion 11 of the oil slinger 2, but since the oil slinger 2 is worn by the shaft member 4 Since the material having more excellent properties is formed, even if the state in which the dust lip 26 is slid to the tubular portion 11 continues, the oil slinger 2 hardly wears.
本發明之一實施形態之主唇25包含壓接環251及連結環252。壓接環251在防塵唇26與內部空間之間抵接於筒狀部11之外周面20。連結環252使壓接環251連結於主環部24之內周端243。The main lip 25 according to an embodiment of the present invention includes a crimp ring 251 and a coupling ring 252. The crimp ring 251 abuts against the outer peripheral surface 20 of the tubular portion 11 between the dust lip 26 and the internal space. The connecting ring 252 connects the crimp ring 251 to the inner peripheral end 243 of the main ring portion 24.
本發明之一實施形態之彈簧環27被安裝於壓接環251。包圍壓接環251之彈簧環27遍及壓接環251之大致全周將朝向軸構件4之旋轉軸之力朝壓接環251施加。如此，壓接環251密接於筒狀部11之外周面20，在壓接環251與筒狀部11之外周面20之間之邊界形成密封功能。收容於內部空間之液體(例如潤滑油等)藉由形成於壓接環251與筒狀部11之外周面20之間之邊界的密封功能而避免朝外部空間漏出。The spring ring 27 according to an embodiment of the present invention is attached to the crimp ring 251. The spring ring 27 surrounding the crimp ring 251 applies a force toward the rotating shaft of the shaft member 4 toward the crimp ring 251 over substantially the entire circumference of the crimp ring 251. In this manner, the crimp ring 251 is in close contact with the outer peripheral surface 20 of the tubular portion 11, and a sealing function is formed at the boundary between the crimp ring 251 and the outer peripheral surface 20 of the tubular portion 11. The liquid (for example, lubricating oil or the like) accommodated in the internal space is prevented from leaking into the external space by the sealing function formed at the boundary between the crimp ring 251 and the outer peripheral surface 20 of the tubular portion 11.
在軸構件4及殼體5中至少一者旋轉之期間，壓接環251會與甩油環2之筒狀部11摩擦，但如上述般，由於甩油環2由與軸構件4相比耐磨耗性更優異之材料形成，故即便在主唇25之壓接環251對筒狀部11滑接之狀態持續之情形下，甩油環2也幾乎不會磨耗。
［產業上之可利用性］While at least one of the shaft member 4 and the housing 5 is rotated, the crimp ring 251 rubs against the cylindrical portion 11 of the oil slinger 2, but as described above, since the oil slinger 2 is compared with the shaft member 4 Since the material having more excellent wear resistance is formed, even when the state in which the crimp ring 251 of the main lip 25 is slid to the tubular portion 11 continues, the oil slinger 2 hardly wears.
