Abstract
The utility model provides a seal anti - formula of putting of oily lip sealing washer for rotation axis, is including seat skeleton and axle sleeve skeleton, the seat skeleton has same block rubber with axle sleeve frame connection, the block rubber bonds there is the oily lip of sealing, the cross section that seals oily lip includes the connecting portion of part no. 1, part no. 2 and part no. 1 and part no. 2, part no. 1 is rectangular with part policy of "literature and art should serve both people and socialism" rectangle, connecting portion are arc -shaped strip, part no. 1, part no. 2 respectively with the seamless butt joint of connecting portion, the arc opening direction of connecting portion is the sealing washer dorsad. Compared with the prior art, the utility model discloses a seal anti - formula of putting of oily lip sealing washer for rotation axis, the arc opening that will seal the main part of oily lip outwards sets up, has reduced the volume of sealing washer main part, not only makes sealing washer simple to operate when using, also can make the whole volume of bearing that is equipped with the sealing washer less simultaneously, has improved the use flexibility ratio of product.
Description
Technical field
The utility model relates to mechanical seal device technical field, particularly the inverted running shaft seal ring of a kind of oil sealing lip.
Background technique
Running shaft seal ring all can arrange oil sealing lip, the cross section of oil sealing lip is mostly smooth circular arc, but when producing seal ring, the circular arc arc core of oil sealing lip is arranged on the inside of seal ring body by technician's custom, namely whole oil sealing lip is positioned at seal ring body, thus increases the volume of seal ring body.
Model utility content
The utility model object is to provide a kind of oil sealing lip inverted running shaft seal ring, is positioned at seal ring body, and increases the technological deficiency of the volume of seal ring body to solve the whole oil sealing lip of traditional seal ring.
The technical solution of the utility model is achieved in that
The inverted running shaft seal ring of a kind of oil sealing lip, comprise a skeleton and axle sleeve skeleton, described seat skeleton and axle sleeve skeleton are connected with same block rubber, described block rubber is bonded with oil sealing lip, the cross section of described oil sealing lip comprises the joint of parts one, parts two and parts one and parts two, and described parts one are rectangular slat with parts two, and described joint is arc strip, described parts one, parts two respectively with joint slitless connection, the arc opening direction seal ring dorsad of described joint.
Preferably, described parts one and block rubber adhesion, described parts one are plane with the junction plane of block rubber.
Preferably, described parts two and the adhesion of axle sleeve skeleton, described parts two are plane with the junction plane of axle sleeve skeleton.
Compared with prior art, the utility model has following beneficial effect:
The inverted running shaft seal ring of oil sealing lip of the present utility model, the arc opening of the main body of oil sealing lip is outwards arranged, reduce the volume of seal ring main body, not only make seal ring easy for installation in use, also can make the bearing integral small volume that seal ring is housed simultaneously, improve the use flexibility ratio of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the inverted running shaft seal ring of the utility model;
Fig. 2 is the enlarged view in A portion in Fig. 1.
In figure: seat skeleton 1, axle sleeve skeleton 2, block rubber 3, oil sealing lip 4, parts 1, parts 2 42, joint 43.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the utility model is clearly and completely described.
As shown in Figures 1 and 2, inverted running shaft seal ring of the present utility model, comprise a skeleton 1 and axle sleeve skeleton 2, wherein seat skeleton 1 and axle sleeve frame 2 can be one-body molded, described seat skeleton 1 is connected with same block rubber 3 with axle sleeve skeleton 2, described block rubber 3 is bonded with oil sealing lip 4, oil sealing lip 4 is plane with the bonding part of block rubber 3, the cross section of described oil sealing lip 4 comprises parts 1, the joint 43 of parts 2 42 and parts 1 and parts 2 42, described parts 1 are rectangular slat with parts 2 42, this kind of structure is in order to oil sealing lip 4 and block rubber 4, axle sleeve skeleton 2 better bonds, described joint 43 is arc strip, described parts 1, parts 2 42 respectively with joint 43 slitless connection, described parts 1, parts 2 42 can be made into integration with joint 43 respectively, the arc opening direction seal ring dorsad of described joint 43, namely the arc space of oil sealing lip 4 does not take the overall space of seal ring, thus reduce the overall space of seal ring, described parts 1 and block rubber 4 adhesion, described parts 1 are plane with the junction plane of block rubber 4, and what oil sealing lip 4 and block rubber 4 can be made like this to bond is more firm, described parts 2 42 and axle sleeve skeleton 2 adhesion, described parts 2 42 are plane with the junction plane of axle sleeve skeleton 2, and what oil sealing lip 4 and axle sleeve skeleton 2 were bonded is more firm.
To sum up structure of the present utility model is known, the inverted running shaft seal ring of oil sealing lip of the present utility model, the arc opening of the main body of oil sealing lip is outwards arranged, reduce the volume of seal ring main body, not only make seal ring easy for installation in use, also can make the bearing integral small volume that seal ring is housed simultaneously, improve the use flexibility ratio of product.
