Abstract

The utility model discloses a kind of micro- bearings of spy with modified form dustproof cover, including the steel ball between bearing outer ring and bearing inner race and the setting bearing outer ring and bearing inner race, the steel ball is kept by retainer, dustproof cover is also set up between the bearing outer ring and bearing inner race, the dustproof cover is located at the both sides of steel ball.The dustproof cover of the utility model is made of cold-rolled steel sheet, in the case of proof strength, its thickness can be greatly reduced with respect to dustproof cover thickness made of rubber, to expand bearing interior space, so that special micro- bearing is in the case of shape size constancy, by increasing the diameter of steel ball, to improve its radial bearing capacity and axial bearing capacity, and extend the service life of special micro- bearing simultaneously.The modified form dustproof cover also allows for installing simultaneously.

Description

A kind of micro- bearing of spy with modified form dustproof cover
Technical field
The utility model is related to technical field of bearings more particularly to a kind of micro- bearings of spy with modified form dustproof cover.
Background technology
Bearing includes that bearing outer ring, bearing inner race and installation are put into steel ball therebetween, and steel ball is protected by retainer It holds.In order to which dustproof cover is arranged in dust-proof and sealing, some bearings also between bearing outer ring and bearing inner race, dustproof cover is located at steel ball Both sides.But existing dustproof cover is substantially made of rubber material, thickness is thicker, occupied bearing interior space compared with More, such dustproof cover is applied in special micro- bearing, can only be to sacrifice steel ball size as generation since the size of special micro- bearing is limited Valence, to place the dustproof cover of such structure type so that the radial bearing capacity and axial bearing capacity of the existing micro- bearing of spy reduce, together When also reduce the physical life of special micro- bearing.
Thus applicant carried out beneficial exploration and trial, result of the above problems is had found, will be detailed below being situated between The scheme to continue is generated under this background.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of tool with defect in view of the deficiencies of the prior art There is the micro- bearing of spy of modified form dustproof cover.
Following technical scheme may be used to realize in the technical issues of the utility model is solved:
A kind of micro- bearing of spy with modified form dustproof cover, including bearing outer ring and bearing inner race and the setting bearing Steel ball between outer ring and bearing inner race, the steel ball are kept by retainer, between the bearing outer ring and bearing inner race Dustproof cover is also set up, the dustproof cover is located at the both sides of steel ball, which is characterized in that two outsides of the inner peripheral surface of the bearing outer ring It is provided with a sealing surface and a dustproof cover card access surface, the sealing surface is mutually perpendicular to the dustproof cover card access surface;It is described dust-proof Grease seal slot is provided in lid card access surface;The dustproof cover is modified form dustproof cover, and the modified form dustproof cover uses cold rolling Steel plate is one time punching molded, and the inner edge of the modified form dustproof cover is circumference compatible with the peripheral surface of the bearing inner race The outer rim in face, the modified form dustproof cover is provided with a seal section and a clamping section, and the clamping section is connect with the seal section And positioned at the outside of the seal section, the clamping section is mutually perpendicular to seal section, the inner surface of the seal section with it is described The sealing surface of bearing outer ring is in sealing contact, and the clamping section is engaged by clamping with the card access surface on the bearing outer ring.
In a preferred embodiment of the utility model, seal section on the modified form dustproof cover is to close to steel ball side To prominent, the clamping section is turned down to far from steel ball direction.
In a preferred embodiment of the utility model, the retainer is molded using cold-rolling steel-plate punch.
Since the dustproof cover of the utility model is made of cold-rolled steel sheet, in the case of proof strength, thickness is opposite Dustproof cover thickness made of rubber can be greatly reduced, to expand bearing interior space so that special micro- bearing is in shape In the case of size constancy, by increasing the diameter of steel ball, to improve its radial bearing capacity and axial bearing capacity, and extend simultaneously The service life of special micro- bearing.The modified form dustproof cover also allows for installing simultaneously.
The utility model can also be by increasing the outer ring channel diameter on bearing outer ring and reducing the inner ring ditch on bearing inner race Diameter further increases bearing interior space, to further increasing the diameter of steel ball.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, other drawings may also be obtained based on these drawings.
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Fig. 2 is the partial enlargement structural representation of the utility model.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under The utility model is expanded on further in face.
A kind of micro- bearing of spy with modified form dustproof cover as shown in Figure 1 to Figure 2, including bearing outer ring 100 and bearing Steel ball 310 between inner ring 200 and setting bearing outer ring 100 and bearing inner race 200, steel ball 310 are protected by retainer 300 It holds, dustproof cover 400 is also set up between bearing outer ring 100 and bearing inner race 200, dustproof cover 400 is located at the both sides of steel ball 310.
Two outsides of the inner peripheral surface of bearing outer ring 100 are provided with a sealing surface 110 and a dustproof cover card access surface 120, it is close Cover 110 is mutually perpendicular to dustproof cover card access surface 120;Grease seal slot 121 is provided in dustproof cover card access surface 120.
The dustproof cover 400 of the utility model is modified form dustproof cover, which is once rushed using cold-rolled steel sheet Molded, the inner edge of modified form dustproof cover is periphery 410 compatible with the peripheral surface 210 of bearing inner race 200, and modified form is anti- The inner edge of dirt lid is sealed cooperation with the peripheral surface 210 of bearing inner race 200.
