In one preferred embodiment of the utility model, the cambered surface and end flat transition position of the cylindrical roller use four / mono- fillet grinding process.

In one preferred embodiment of the utility model, the periphery of the cylindrical roller and the forced contact plate are rolled Contact.

In one preferred embodiment of the utility model, deformation position-limit mechanism is connected in the bradyseism spring.

The beneficial effects of the utility model are: the utility model is mounted with that can reduce bearing radially presses in the inside of bearing The cushioning device of power, roller is by one piece of stressed plate of contact and inner ring and outer ring mediate contact, and the rear end of stressed plate is connected with Pressure can soon be dissolved when inner ring or outer ring apply pressure to roller in this way, be avoided by spring cushioning device Deformation occurs for roller.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

Fig. 1 is the structural schematic diagram for one preferred embodiment of automobile bearing that the utility model has radial shock-absorbing function；

The components in the drawings are labeled as follows: 1, bearing inner race；2, bearing outer ring；3, cylindrical roller；4, retainer；5, on Groove；6, lower groove；7, forced contact plate；8, bradyseism spring.

Specific embodiment

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Referring to Fig. 1, the utility model embodiment includes:

A kind of automobile bearing with radial shock-absorbing function, including bearing inner race 1, bearing outer ring 2, cylindrical roller 3 and guarantor Frame 4 is held, the inner peripheral surface of the bearing outer ring 2 sets the upper groove 5 of circle recess, and the peripheral surface of the bearing inner race 1 sets one The lower groove 6 of recess is enclosed, the bearing inner race 1 is set to inside the centre bore of the bearing outer ring 2,3 sandwiched of cylindrical roller In void layer between the bearing inner race 1 and the bearing outer ring 2, the retainer 4 is connected to the cylindrical roller 3 A circle forced contact plate 7 is set at the outer openings of both ends, the upper groove 5 and the lower groove 6, the forced contact plate 7 Centre is slab construction, and the edges at two ends of the forced contact plate 7 forms quarter circular arc, upper 5 He of groove outward The inside of the lower groove 6 is equipped with bradyseism spring 8, described 8 one end of bradyseism spring and the bearing inner race 1 or the bearing outer ring 2 connections, the other end of the bradyseism spring 8 are connected to the bottom surface of the forced contact plate 7.

In addition, the cambered surface of the cylindrical roller 3 and end flat transition position use a quarter fillet grinding process.

In addition, the periphery of the cylindrical roller 3 is in rolling contact with the forced contact plate 7.

In addition, connecting deformation position-limit mechanism in the bradyseism spring 8.

The working principle of the utility model is that the inner peripheral surface of bearing outer ring 2 sets the upper groove 5 of circle recess, bearing inner race 1 peripheral surface sets the lower groove 6 of circle recess, and bearing inner race 1 is set to inside the centre bore of bearing outer ring 2, and cylindrical roller 3 presss from both sides It is located in the void layer between bearing inner race 1 and bearing outer ring 2.

Retainer 4 is connected to the both ends of cylindrical roller 3, sets a circle stress at the outer openings of upper groove 5 and lower groove 6 and connects The centre of touch panel 7, forced contact plate 7 is slab construction, and the edges at two ends of forced contact plate 7 forms quadrant outward Arc, the cambered surface and end flat transition position of cylindrical roller 3 use a quarter fillet grinding process, the periphery of cylindrical roller 3 It being in rolling contact with forced contact plate 7, so that it is more firm and closely that cylindrical roller 3 and forced contact plate 7 can be chimeric,

The inside of upper groove 5 and lower groove 6 is equipped with outside bradyseism spring 8,8 one end of bradyseism spring and bearing inner race 1 or bearing 2 connection of circle, the other end of bradyseism spring 8 are connected to the bottom surface of forced contact plate 7, apply in inner ring or outer ring to roller press in this way Soon pressure can be dissolved when power, avoiding cylindrical roller 3, deformation occurs, connection deformation limit in bradyseism spring 8 Mechanism can be extruded or stretch to avoid spring is excessive.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases The technical field of pass, is also included in the patent protection scope of the utility model.
