Sealing ring or dust cover, to meet the requirement of its leakproofness.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of automobile middle control knob bearings, to solve prior art middle (center) bearing
Adjustable axial displacement is smaller and bearing on for assembling the complex technical problem of the structure of injection moulded components.
To achieve the above object, the present invention provides a kind of automobile middle control knob bearing, comprising: outer ring, inner ring and retainer,
Steel ball fixed bit is provided on the retainer；It is provided with outer ring raceway on the outer ring, inner ring rolling is provided on the inner ring
Road, the outer ring raceway and the inner ring raceway are positioned opposite, are provided with steel between the outer ring raceway and the inner ring raceway
Ball, the steel ball are stuck in the steel ball fixed bit.
Further, the opening of the steel ball fixed bit is provided with locking device.
Further, lubricating grease is provided in the inner ring raceway and the outer ring raceway.
Further, the steel ball fixed bit is provided with 19.
Further, 19 steel ball fixed bits are uniformly arranged on the retainer.
Further, the retainer is made of nylon material.
Further, gap is reserved between the retainer and the inner ring, the gap is 0.05mm.
Compared with prior art, present invention produces following the utility model has the advantages that a kind of automobile middle control knob bearing of the invention,
The device between inner ring and outer ring by being arranged steel ball, and with retainer come this technical solution of stationary balls, so that
The apparatus structure is simple, and bearing does not need to be equipped with special sealing ring or dustproof cover, before guaranteeing axial displacement a distance
It puts, accomplishes to move up and down steady and smooth, be able to maintain and preferably turn round flexible performance.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
Fig. 1-5 is please referred to, the preferred embodiment of the present invention provides a kind of automobile middle control knob bearing, comprising: outer ring 1,
Inner ring 2 and retainer 3 are provided with steel ball fixed bit 4 on the retainer 3；Outer ring raceway 5 is provided on the outer ring 1, it is described
Inner ring raceway 6 is provided on inner ring 2, the outer ring raceway 5 and the inner ring raceway 6 are positioned opposite, the outer ring raceway 5 and institute
It states and is provided with steel ball 7 between inner ring raceway 6, what the steel ball 7 was adapted is stuck in the steel ball fixed bit 4.Use principle: outer
Circle 1 has biggish outer diameter and circle wall is relatively thin, and outer ring raceway 5 is directly ground by forming grinding wheel, substantially increases bearing axis
To mobile smooth sense；In actual use, fixed outer ring 1, push or pull-up inner ring 2, it can be achieved that bearing a distance axis
Hold displacement function；Or fixed inner ring 2, outer ring 1 is pushed or pulled up, can also equally realize the bearing displacement function of bearing a distance
Energy；The device between inner ring 2 and outer ring 1 by being arranged steel ball 7, and with retainer 3 come this technical solution of stationary balls 7,
So that the apparatus structure is simple, bearing does not need to be equipped with special sealing ring or dustproof cover, and device sealing requirements are by assembling
The injection molding of extraneous part is completed, and under the premise of guaranteeing axial displacement a distance, accomplishes to move up and down steady and smooth, Neng Goubao
It holds and preferably turns round flexible performance.
Preferably, the opening of the steel ball fixed bit 4 is provided with locking device 8, and steel ball fixed bit 4 is for dividing steel ball
7, locking device 8 prevents steel ball 7 from dropping out from steel ball fixed bit 4.
Preferably, it is provided with lubricating grease in the inner ring raceway 6 and the outer ring raceway 5, so that bearing element face shape
At one layer of oil film, Bearing inner friction is reduced.
Preferably, the steel ball fixed bit 4 is provided with 19, and 19 steel ball fixed bits 4 are equal on the retainer 3
Even setting enhances the intensity of retainer 3.
Preferably, the retainer 3 is made of nylon material, and nylon has the performance of self-lubricating, and nylon material is revolved in bearing
