Abstract
A kind of mute type car steering tube column special bearing, belongs to rolling bearing field.Existing deep groove ball bearing, which exists, to be assembled numerous and diverse, easy generation and rocks and the problem of noise, the utility model includes inner ring, retainer, rolling element and outer ring, rolling element is supported in the raceway being installed between inner ring and outer ring by retainer, described outer ring is elastomer straight forming, the raceway bottom of trench of outer ring and inner ring is designed with ring-shaped groove, make there is gap between rolling element and raceway bottom of trench, and in 4 angular contacts between two raceways, outer ring is elasticity of plastics outer ring, and elasticity of plastics outer ring passes through injection molding.The utility model can bear radial load and axial force, and bearing stability is good, easy to assembly and can reduce noise.
Description
Technical field
The utility model belongs to rolling bearing field, especially relevant with a kind of mute type car steering tube column special bearing.
Background technology
All it is between metal material for supporting between traditional ball bearing roller kinetoplast of car steering tube column and inner ring, outer ring
Rigid contact, and can only typically bear radial load, cause automotive steering structure to be also easy to produce play in the course of the work, it is stable
Property is poor, and also easily produces larger noise.The utility model patent of Application No. 200990100506.2 discloses one
The rolling bearing system for steering column for vehicles is planted, attached raceway composition outer ring is used as by being embedded two cylinder rings in housing
Interior raceway, sets elastic ring to support cylinder ring by a cylinder ring side wherein, and the spacing formation to two cylinder rings is adjusted
Section, the pressure between bearing roller and Internal and external cycle can be adjusted, and realize between rolling element and raceway to be corner connection
Touch, rocking and noise when reducing automotive steering structure work, but such ball bearing structure is complex, assembles number
It is tired.
Utility model content
The purpose of this utility model is intended to overcome the traditional deep groove ball bearing assembling for being currently used for steering column for vehicles support numerous
Miscellaneous, easy generation is rocked with the defect of noise can bear radial load and axial force there is provided one kind, and bearing stability is good, assembling side
Just and the mute type car steering tube column special bearing of noise can be reduced.
Therefore, the utility model uses following technical scheme：A kind of mute type car steering tube column special bearing, including it is interior
Circle, retainer, rolling element and outer ring, rolling element are supported in the raceway being installed between inner ring and outer ring by retainer, and it is special
Levy and be：Described outer ring is elastomer straight forming, and the raceway bottom of trench of outer ring and inner ring is designed with ring-shaped groove, makes rolling element
There is gap between raceway bottom of trench, and in 4 angular contacts between two raceways.
As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
The outer ring is elasticity of plastics outer ring, and elasticity of plastics outer ring passes through injection molding.
The utility model can reach following beneficial effect：1st, by the way that bearing outer ring is directly molded into plastic outer ring, than
Existing steering column for vehicles bearing simplifies structure, makes its easy to assembly, improves the efficiency of assembling of bearing；2nd, by inside and outside
Groove is set on circle raceway, makes the single-contact between original rolling element and two raceways into 4 angular contacts, makes it with footpath
Also there is axial load power simultaneously on the basis of to load force, bearing is not produced in the course of the work and rock, the course of work
Middle (center) bearing noise is small, meanwhile, bearing stability is good, and improves bearing products quality.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is enlarged drawing at a in Fig. 1.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model includes inner ring 1, retainer 3, rolling element 2 and elasticity of plastics outer ring 4, rolling
Kinetoplast 2 is supported in the raceway that is installed between inner ring 1 and elasticity of plastics outer ring 4 by retainer 3, elasticity of plastics outer ring 4 and interior
The raceway bottom of trench of circle 1 is designed with ring-shaped groove 5, makes the presence of gap between rolling element 2 and raceway bottom of trench, and be between two raceways
4 angular contacts, make bearing while having radial load and axial force, the elasticity of plastics outer ring 4 passes through injection molding.
