Description

Rubber non-slip mat

Technical Field

The utility model relates to a packing ring technical field, concretely relates to are rubber slipmat.

Background

The driving motor is a power source of a new energy automobile and is similar to an engine of a conventional fuel automobile. The motor mainly comprises a rotor assembly, a stator assembly, a motor shell, a front end cover, a rear end cover, a rotary transformer and the like. The rotor assembly has the axis of rotation, and the tip cover of axis of rotation is equipped with the bearing, and the bearing is mutually supported with end cover bearing chamber, guarantees that the rotor assembly rotates more steadily.

When an existing driving motor is assembled, a wave washer is additionally arranged between a bearing and a bearing cavity, the wave washer can generate axial pretightening force, and the driving motor has good elasticity, shock resistance and other performances. However, most of the bearings are in clearance fit with the bearing cavities, and because the wave washers can only generate axial pretightening force, the bearing can run out of the ring under the action of inertia when rotating at high speed, namely the outer ring of the bearing rotates, so that the service life of the bearing is greatly reduced.

In view of the above, the applicant has made an intensive study to solve the above problems and has made the present invention.

Disclosure of Invention

The utility model discloses a main aim at provides a rubber slipmat can provide the axial pretightning force for the bearing, satisfies bearing operating condition, can provide the frictional force of direction of rotation again to the bearing inner race in order to prevent to run the outer lane, can also stop the unusual noise that produces behind the former ripples spring structure race ring.

In order to achieve the above purpose, the solution of the present invention is:

the utility model provides a rubber non-slip mat, includes the non-slip mat main part, the upper end of non-slip mat main part is equipped with first cushion and the first recess that the interval set up, the lower extreme of non-slip mat main part is equipped with second cushion and the second recess that the interval set up, the second cushion corresponds the below that sets up at first recess, the second recess corresponds the below that sets up at first cushion.

Furthermore, interference convex points which are evenly distributed are arranged on the side face of the non-slip mat main body.

Furthermore, the interference salient points are arranged on the side edges of the first cushion block and the second cushion block at intervals.

Furthermore, the side edge of the interference convex point is provided with a fillet.

Furthermore, the inside of slipmat main part is equipped with support ring portion.

Compared with the prior art, beneficial effect lies in:

1. the utility model discloses a set up first cushion, first recess, second cushion and second recess for the slipmat main part is the wave structure, and the wave structure can produce better axial pretightning force, and the upper surface of first cushion can support the laminating with the lower surface of bearing inner race, and the lower surface of second cushion can support the laminating with the bottom of bearing chamber, thereby produces radial frictional force, prevents that the bearing inner race from rotating, avoids the bearing to take place the phenomenon of "race circle".

2. The utility model discloses a side is equipped with the interference bump, through the design of interference magnitude, ensures that the product is difficult for dropping in putting into the bearing cavity, provides the manufacturability of assembly.

3. The inside of slipmat main part is equipped with support ring portion, can further strengthen the overall structure intensity of slipmat main part, improves slipmat main part rigidity and life.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1-3, a rubber non-slip mat comprises an annular non-slip mat main body 1, wherein the upper end of the non-slip mat main body 1 is provided with a first cushion block 2 and a first groove 3 which are arranged at intervals, the lower end of the non-slip mat main body 1 is provided with a second cushion block 4 and a second groove 5 which are arranged at intervals, the second cushion block 4 is correspondingly arranged below the first groove 3, and the second groove 5 is correspondingly arranged below the first cushion block 2. Adopt above-mentioned structure for slipmat main part 1 is the wave structure, and the wave structure can produce better axial cushion power, and slipmat main part 1 adopts rubber materials to make, and rubber materials compares the wave form packing ring of metal and has certain material elasticity, can further improve the cushioning effect to the bearing. In addition, the upper surface of the first cushion block 2 can abut against and attach to the lower surface of the bearing outer ring, and the lower surface of the second cushion block 4 can abut against and attach to the bottom of the bearing cavity, so that friction force in the horizontal direction is generated, the bearing outer ring is prevented from rotating, and the phenomenon that the bearing runs out of the ring is avoided.

Preferably, the side surface of the non-slip mat main body 1 is provided with interference convex points 6 distributed uniformly. After adopting above-mentioned structure, interference bump 6 can support the friction with the lateral wall of bearing chamber, improves the non-slip effect of slipmat main part 1, prevents that slipmat main part 1 from taking place to rotate for slipmat main part 1 installs more firmly. And the interference salient points 6 are arranged at the side edges of the first cushion block 2 and the second cushion block 4 at intervals. So set up and make interference bump 6 can be fixed simultaneously to the upper end part and the lower tip of slipmat main part 1, and the installation of slipmat main part 1 is more firm. In addition, the side edge of the interference bump 6 is provided with a rounded corner. The novel non-slip mat is convenient to be arranged in the bearing cavity.

Preferably, the inside of slipmat main part 1 is equipped with support ring portion 7, and second cushion 4 and second recess 5 inwards extend to the lower extreme of support ring portion 7, adopt above-mentioned structure, can further strengthen the overall structure intensity of slipmat main part 1, improve the life of slipmat main part 1.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
