Description

Ball bearing with plane shield

Technical Field

The utility model relates to a bearing field especially relates to a ball bearing with plane shield.

Background

Ball bearing is a mechanical part very commonly used, generally all can install the shield between ball bearing's outer lane and inner circle, and present shield structure is complicated, and the axial width space that occupies the bearing more can be more, and if planar shield then intensity is not enough, and the leakproofness also can't satisfy the requirement, and plane shield is easy deformation in the installation moreover.

SUMMERY OF THE UTILITY MODEL

The utility model provides a ball bearing with plane shield, simple structure has changed the structure of plane shield, solves the problem among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a ball bearing with plane shield, includes bearing inner race and bearing inner race, bearing inner race and bearing inner race between be provided with the steel ball, the steel ball outside install the holder, bearing inner race and bearing inner race between both sides embedding install the shield, the shield be the plane ring form, its inside is close to radial outside edge and is provided with the skeleton ring, the inboard edge of shield imbed in the sealed recess in the circumference outside of bearing inner race.

Preferably, a clamping groove is formed in the position, close to the end face, of the circumferential inner side wall of the bearing outer ring, and a guide conical surface is arranged between the clamping groove and the end face of the bearing outer ring.

Alternatively, the radial outer edge of the dustproof cover is provided with an outer conical surface.

Preferably, the radial width of the skeleton ring is one half of the radial width of the dust cover.

Compared with the prior art, the beneficial effects of the utility model are that:

simple structure has changed the structure of plane shield, combines together plane shield design for rigidity and flexible construction, has guaranteed the installation intensity and the leakproofness of plane shield, and the design has installation guide structure, makes things convenient for the installation of plane shield.

fig. 2 is an enlarged view of a structure of fig. 1.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, the utility model provides a ball bearing with plane shield, including bearing inner race 1 and bearing inner race 2, bearing inner race 1 and bearing inner race 2 between be provided with

steel ball

3, 3 outsides of steel ball install holder 7, a serial communication port, bearing inner race 1 and bearing inner race 2 between both sides embedding install shield 4, shield 4 be the plane ring form, its inside edge that is close to radially outside is provided with skeleton ring 11, shield 4 inside edge imbed in the sealed recess 6 in the circumference outside of bearing inner race 2.

The skeleton ring 11 and the dust cap 4 are integrally formed by vulcanization, and the skeleton ring 11 mainly plays a role in clamping and fixing and providing strength, so that the dust cap 4 is not easy to fall off when the bearing is used.

The inner part of the dust cover 4 is made of rubber materials and is clamped into the sealing groove 6, and the sealing effect is achieved when the inner ring rotates.

As an installation embodiment of the utility model, the circumference inside wall of bearing inner race 1 on be provided with joint groove 9 near the position of terminal surface, joint groove 9 and 1 terminal surface of bearing inner race between be provided with the direction conical surface 10, play direction and anti-sticking dead effect when can making shield 4 card go into through the direction conical surface 10.

In order to further facilitate clamping installation of the dust cover 4, the outer edge of the radial outer side of the dust cover 4 is provided with an outer conical surface 8, and the outer conical surface 8 is in contact with the guide conical surface 10 during installation, so that the installation of the dust cover 4 is facilitated.

In order to support the whole dust cap 4 by the skeleton ring 11, the radial width of the skeleton ring 11 is half of the radial width of the dust cap 4.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the various features of the disclosed embodiments of the present invention can be used in any combination with each other, and the description of such combinations is not exhaustive in the present specification only for the sake of brevity and resource conservation. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
