Description

A kind of oil seal of differential protecting tool set-up

Technical field

The utility model relates to tooling auxiliary tool technical field, especially a kind of oil seal of differential protecting tool set-up.

Background technique

Automobile axle shaft is also referred to as drive shaft, and interior outer end respectively has a universal joint respectively by the spline and differential on universal joint Device and driving wheel connect.

Oil sealing is also known as oil baffle, and the position of all each mechanism rolling bearings or plain bearings of automobile requires installation oil sealing It prevents leaking and leaking for lubricating oil or lubricating grease, while preventing the immersion of dust or sludge again, maintain rolling or sliding The good lubrication condition of friction parts, prolongs the service life.

Semiaxis is assembled to during differential mechanism, and spline easily collides oil seal of differential, is caused oil sealing crackle, is scratched, can make difference Lubricating oil is reduced in fast device, is influenced normally to lubricate, is aggravated the abrasion of parts and lead to earlier period damage.

Utility model content

The purpose of the utility model is to provide a kind of oil seal of differential protecting tool set-ups, to solve differential mechanism in the prior art The technical problem of oil sealing position breakage.

The utility model provides a kind of oil seal of differential protecting tool set-up, including matrix and coaxially connected in the matrix On convex block, the matrix and the convex block are cylindrical structure, are run through at the central axis of the matrix and the convex block There is circular groove, the internal diameter of the circular groove and the outer diameter of semiaxis are adapted, and the inner wall of the circular groove radially extends jagged, the notch Axially penetrate through the matrix and the convex block.

Oil seal of differential protecting tool set-up as described above, wherein preferably, the matrix and the convex block are rubber Material.

Oil seal of differential protecting tool set-up as described above, wherein preferably, the side of the matrix is convexly equipped with lug.

Oil seal of differential protecting tool set-up as described above, wherein preferably, the lug inclination is connected to the matrix On.

Oil seal of differential protecting tool set-up as described above, wherein preferably, the axis of the lug and the matrix Axis angle is 45 °.

Oil seal of differential protecting tool set-up as described above, wherein preferably, the axial location of the lug is logical through having Hole.

Compared with prior art, the utility model uses light, and installation, disassembly are quick, and assembly semiaxis before prevents oil sealing Nurse is installed on oil sealing position and takes out oil sealing protective tooling after semiaxis is put into oil sealing, keep away to ensure that in assembling process Exempt from spline to collide with oil sealing, improves product quality.

Description of symbols: 1- matrix, 2- convex block, 3- circular groove, 4- notch, 5- lug, 6- through-hole.

Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model Limitation.

As shown in Figure 1 to Figure 3, the embodiments of the present invention provide a kind of oil seal of differential protecting tool set-up, including base Block 1 and coaxially connected in the convex block 2 on the matrix 1, the matrix 1 and the convex block 2 are cylindrical structure, the base Through there is circular groove 3 at the central axis of block 1 and the convex block 2, the internal diameter of the circular groove 3 and the outer diameter of semiaxis are adapted, described The inner wall of circular groove 3 radially extends jagged 4, and the notch 4 axially penetrates through the matrix 1 and the convex block 2.

Oil sealing protective tooling is placed in oil sealing position before assembly semiaxis, then semiaxis is passed through into circular groove 3, semiaxis is put into oil sealing After interior, this oil sealing protective tooling is taken out by notch 4, avoids spline to collide with oil sealing in assembling process to ensure that, is promoted Product quality.

Further, the matrix 1 and the convex block 2 are rubber material, are formed by integrated vulcanizing, when energy is long in this way Between keep elasticity, avoid colliding with and damage semiaxis, and semiaxis is promoted to be easy to take out out of notch 4.

Further, the side of the matrix 1 is convexly equipped with lug 5, and such operator conveniently passes through grasping tabs 5, comes This oil seal protective tooling is detached from semiaxis by force.

Further, to avoid lug 5 from causing to interfere, collide with components, so lug 5 is designed as avoiding structure, specifically Ground, the inclination of lug 5 are connected on the matrix 1.

Further, the axis angle of the axis of the lug 5 and the matrix 1 is 45 °, to facilitate processing and forming, and Operator is facilitated to exert a force.

Further, the axial location of the lug 5 is through there is through-hole 6, to facilitate other auxiliary instruments to wear fixation, increases Add the versatility and application range of this oil seal protective tooling.

The structure, features, and effects of the present invention is described in detail based on the embodiments shown in the drawings, with Upper described is only the preferred embodiment of the utility model, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to Change or equivalent example modified to equivalent change made by conception according to the utility model, still without departing from specification and figure When showing covered spirit, it should be within the protection scope of the present utility model.
