Abstract
Low-noise automobile steering column special bearing, belongs to rolling bearing field.Existing deep groove ball bearing, which exists, assembles numerous and diverse, easily produce and rock and the problem of noise, the utility model includes inner ring, retainer, rolling element and outer ring assembly, outer ring assembly includes elastomer outer ring and case, rolling element is supported in the raceway being installed between inner ring and elastomer outer ring by retainer, the raceway bottom of trench of elastomer outer ring and inner ring is equipped with ring-shaped groove, make there is gap between rolling element and raceway bottom of trench, and in 4 angular contacts between two raceways, the case is in a ring, case two ends are equipped with radially inner radial direction flange, form the annular accommodating cavity for housing the elastomer outer ring, the top of one of them radial direction flange on case is bent to form axial flange towards rolling element.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 low-noise automobile steering 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 car steering tube column special bearing of noise can be reduced.
Therefore, the utility model uses following technical scheme：Low-noise automobile steering column special bearing, including inner ring,
Retainer, rolling element, it is characterised in that：The bearing also includes outer ring assembly, and outer ring assembly includes elastomer outer ring and case,
Rolling element is supported in the raceway being installed between inner ring and elastomer outer ring by retainer, the raceway of elastomer outer ring and inner ring
Bottom of trench is designed with ring-shaped groove, makes the presence of gap between rolling element and raceway bottom of trench, and in 4 angular contacts between two raceways,
In a ring, case two ends are equipped with radially inner radial direction flange to the case, are formed for housing the elastomer outer ring
The top of one of them radial direction flange on annular accommodating cavity, case is bent to form axial flange towards rolling element, axially
Flange makes the outer ring be connected with case, displacement difficult for drop-off.
As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
The elastomer outer ring is plastic outer ring, and plastic outer ring is molded in the annular accommodating cavity of the case.
The top of one of them radial direction flange on the case is bent to form axial flange towards rolling element.
The utility model can reach following beneficial effect：1st, by the outer ring assembly being made up of plastic outer ring and case,
Plastic outer ring is molded in the annular accommodating cavity of outsourcing housing, and the structure is simpler than existing steering column for vehicles bearing arrangement,
So that it is easy to assembly, improve bearing efficiency of assembling；2nd, including, groove is set on outer ring raceway, by original rolling element with
Single-contact between two raceways makes 4 angular contacts into, makes it on the basis of with radial load power while also having axially negative
Power is carried, bearing is not produced in the course of the work and rocks, course of work middle (center) bearing noise is small, meanwhile, bearing stability is good, phase
Bearing products quality should be improved.
Brief description of the drawings
Fig. 1 is structural profile schematic diagram 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 2, rolling element 3 and outer ring assembly, outer ring assembly
Including elastomer outer ring 5 and case 4, rolling element 3 supports the rolling being installed between inner ring 1 and elastomer outer ring 5 by retainer 2
In road, the raceway bottom of trench of elastomer outer ring 5 and inner ring 1 is designed with ring-shaped groove 7, makes to exist between rolling element 3 and raceway bottom of trench
Gap, and in 4 angular contacts between two raceways, in a ring, the two ends of case 4 are equipped with radially inner footpath to the case 4
To flange, one of them the described radial direction flange formed on the annular accommodating cavity for housing the elastomer outer ring 5, case 4
Top be bent to form axial flange 6 towards rolling element 3, axial flange 6 makes the outer ring be connected with case, position difficult for drop-off
Move, the elastomer outer ring 5 is plastic outer ring, plastic outer ring is molded in the annular accommodating cavity of the case 4.
