Abstract
The utility model discloses an elastic housing washer punching sleeve bearing, comprising a drawn cup, a rolling element and a retainer, wherein, the drawn cup is a triangle with non-circular cambered sides, the peripheral surface of the drawn cup is provided with at least three externally convex circular beads which are uniformly distributed, and the three cambered sides are respectively connected with the circular beads, the two of which are adjacent with each other. After the bearing is arranged in a motor steering shaft, three larger diametral clearances exist between the three cambered sides of the drawn cup and an inner hole of a bearing block, so as to ensure the bearing to float and drift to enclasp the motor steering shaft and eliminate the windage of the bearing. When the automobile runs in a bumpy state, under the action of the external force and the reaction of the elastic force of the drawn cup of the bearing of the utility model, the radial relative position between the steering shaft of a traversing mechanism of the automobile and the bearing block of the traversing mechanism can float and drift in an elastic way, therefore, under any road condition, the swing of the traversing mechanism of the automobile can be flexible swing, thereby improving the travelling comfort of automobilism.
Description
Technical field
The utility model relates to a kind of drawn cup bearing, relates in particular to a kind of bearing that is used on the automobile steering machine steering shaft, belongs to technical field of bearings.
Background technique
Automobile in the process of moving, reason can cause automobile bumpiness owing to road conditions are bad etc., at this moment, the automobile steering machine will be swung simultaneously with automobile.Connecting between the bearing of existing automobile steering machine steering shaft and the steering axles is that Spielpassung connects, and bearing clearance is arranged between steering shaft and the bearing roller, and the connection between steering shaft and the direction arbor bearing is a rigid joint.When automobile running jolts, because the radially relative position rigidity between the inner hole of bearing seat of steering shaft and automobile steering machine is constant, therefore when swing takes place along with jolting of automobile in the direction machine, this oscillatory forces directly passes on the steering wheel of driver's assurance, has influenced the travelling comfort of car steering.
The model utility content
When travelling in order to overcome existing automobile bumpiness, because the adverse effect that the radially relative position rigidity between the inner hole of bearing seat of automobile steering machine steering shaft and direction machine is constant to be produced to the travelling comfort of car steering, the utility model provides a kind of elasticity outer ring punching press cover bearing, when automobile bumpiness, this bearing can reduce the oscillatory forces of direction machine steering shaft greatly, has improved the travelling comfort of car steering.
The purpose of this utility model is achieved by the following technical programs.
A kind of elasticity outer ring punching press cover bearing, comprise drawn cup, rolling element, retainer, described rolling element is arranged in the retainer by the interval annular that equates, described drawn cup is the arc triangle edge of non-circle, at least three uniform evagination fillets are set on the outer circumferential face of described drawn cup, and three arc limits connect adjacent in twos fillet respectively.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid a kind of elasticity outer ring punching press cover bearing, the outer circumferential face of wherein said drawn cup is provided with the uniform flute profile flange at least three places, and described flute profile flange is positioned at the outside at rolling element two ends.
Aforesaid a kind of elasticity outer ring punching press cover bearing, wherein said drawn cup is an elastomer, its surface hardness is 640～800HV
0.1
Because drawn cup of the present utility model is the arc triangle edge of non-circle, this bearing is packed into behind the bearing support of direction machine, there is the bigger radial clearance in three places between three the arc limits of its drawn cup and the endoporus of bearing support, when automobile bumpiness travels, under the reaction of the elastic force of the drawn cup of jolt external force effect and the utility model bearing, but the radially relative position elastic floating between the bearing support of automobile steering machine steering shaft and direction machine, therefore under any road conditions, the swing of automobile steering machine all is flexible swing, thereby has improved the travelling comfort of car steering.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a main structure view of the present utility model.
Fig. 2 is pack into a topology view after the automobile steering arbor bearing of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, elasticity of the present utility model outer ring punching press cover bearing is made up of drawn cup 1, rolling element 2, retainer 3, and rolling element 2 is arranged in the retainer 3 by the interval annular that equates.At least three uniform evagination fillets 11,12,13 are set on the outer circumferential face of drawn cup 1, and arc limit 14,15,16 connects adjacent in twos fillet 11,12,13 respectively, has constituted the drawn cup 1 of the arc triangle edge of non-circle.
The outer circumferential face of drawn cup 1 is provided with the uniform flute profile flange at least three places 17,18,19, and this flute profile flange 17,18,19 is used for being positioned at the axial limiting of rolling element 2.Drawn cup 1 is an elastomer, and its surface hardness is 640～800HV
0.1
Fig. 2 shows the state that the utility model is put into the bearing support 4 of direction machine, and direction machine steering shaft 5 is packed among the rolling element 2 of annular array, and rolling element 2 is tightly embraced direction machine steering shaft 5, does not have the gap between the two.Three uniform evagination fillets 11,12,13 of drawn cup 1 respectively with endoporus 41 interference fit of bearing support 4, have the bigger radial clearance 6,7,8 in three places between three the arc limits 14,15,16 of drawn cup and the endoporus of bearing support.When automobile bumpiness travels, under the reaction of drawn cup 1 elastic force of power effect outside and the utility model bearing, radially relative position between the endoporus 41 of the bearing support 4 of direction machine steering shaft 5 and direction machine is elastic floating in the larger context, the automobile steering machine can flexible be swung, direction machine steering shaft 5 is relatively stable, the active force that passes on the steering wheel that the driver holds reduces greatly, has improved the travelling comfort of car steering.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
