Description
Technical Field
The utility model relates to a bearing field especially relates to an adopt ball bearing of flexible 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 all is rigid structure, and at long-time operation in-process, ball bearing's inner circle and outer lane all can be the ovalization, will produce the clearance between rigid shield and the inner circle, and the clearance can influence dustproof effect, so need a new shield.
In addition, since the ball bearing may be repaired at a later stage, the dust cap needs to be removed, and the existing dust cap is generally difficult to remove, and even the dust cap is difficult to remove destructively, so that improvement is needed.
SUMMERY OF THE UTILITY MODEL
The utility model provides an adopt ball bearing of flexible shield, simple structure has changed original shield, has improved the leakproofness, and the shield dismantlement is easier moreover.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an adopt ball bearing of flexible 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 include the supporting part and be located the dependence portion in the radial outside of supporting part, the radial inboard of supporting part be provided with the flexible sealing portion of round, the inboard edge and the bearing inner race of flexible sealing portion contact, supporting part and dependence portion between link to each other through inclined plane transition portion, inclined plane transition portion on be provided with round wedge sand grip or round inner groovy.
Preferably, a dustproof groove is formed in the circumferential inner side wall of the bearing outer ring, a crimping portion is arranged at the edge of the depending portion, and the crimping portion is embedded into the dustproof groove.
As another option, the circumference lateral wall of bearing inner race on be provided with the seal groove, the inboard edge of flexible sealing portion be provided with first seal lip and second seal lip, first seal lip and the inboard lateral wall of seal groove contact, the outside upper edge of second seal lip and seal groove contact.
Preferably, the support part and the flexible sealing part are integrally formed by vulcanization.
Compared with the prior art, the beneficial effects of the utility model are that:
the structure is simple, the original dustproof cover is changed, the dustproof cover consists of a rigid part and a flexible part, the installation firmness is met, and meanwhile, the sealing performance is improved so as to adapt to the deformation of the bearing;
have and be provided with wedge sand grip or inner groovy on the shield, conveniently make the shield dismantle as the stress point in the maintenance.
