Abstract
The utility model relates to a current balance ball bearing for an automobile steering column, comprising an outer ring, an inner ring, a steel ball and a cage. A circumferential first groove is arranged on the inner wall of the outer ring, a circumferential second groove corresponding to the position of the first groove is arranged on the outer wall of the inner ring, and a snap ring is arranged between the first groove and the second groove. The utility model forms a balance current structure by the matching of the snap ring with the bearing outer ring and the inner ring to prevent the electric discharge generation due to potential difference, avoid the electric corrosion or firing situation generated in inner and outer ring runners of the bearing, guarantee the stable performance of the bearing, and improve the service life of the bearing, thereby improving the service life of the automobile steering system and guaranteeing the use security of the automobile.
Description
Technical field
The utility model relates to the bearing that is used for automobile, specifically a kind of current balance type ball bearing that is used for steering column for vehicles.
Background technique
Along with improving constantly of quality of life nowadays, people are also constantly improving the life-span and the safe requirement of vehicle driving.Safety performance and life-span that vehicle uses are high more, and be also just higher to the safety and the life requirements of each parts of vehicle.Vehicle steering wheel is connected with the steering equipment on chassis with rotatingshaft by steering column, the life-span of automobile steering system and Safety performance badly influence driver's personal safety, and the life-span of steering stem bearing has a strong impact on the life-span of steering system, so the performance of steering stem bearing directly affects the working life of wheel steering system even the Security of operation.The steering column for vehicles bearing generally uses deep groove ball bearing; but nowadays the steering system of some automobiles has increased helping to the thrust function of energising for the torsional moment that reduces steering wheel; making deep groove ball bearing the bearing race surface occur through regular meeting in actual moving process is drunk wound and is shifted to an earlier date failure phenomenon; and then bearing was lost efficacy in advance, thereby influence the Security of automobile.
Summary of the invention
The utility model provides a kind of current balance type ball bearing that is used for steering column for vehicles at the problems referred to above, and this bearing can reduce bearing very effectively and the Internal and external cycle raceway in use occur by electro erosion or meal with wine burning phenomenon, guarantees the stable performance of bearing.
According to the technical solution of the utility model: a kind of current balance type ball bearing that is used for steering column for vehicles, comprise outer ring, inner ring, steel ball and retainer, the inwall of described outer ring is provided with circumferential first groove, the outer wall of described inner ring is provided with and corresponding circumferential second groove of described first groove location, is provided with snap ring between described first groove and described second groove.
The cross section of described first groove and described second groove is a V-type.
The height of the outside trough rim of described V-type first groove is lower than the height of its inside slot edge, and accordingly, the height of the outside trough rim of described V-type second groove is lower than the height of its inside slot edge.
Described first groove and described second groove have two respectively, and two first grooves are symmetricly set in the two ends of described outer ring inwall, and two second grooves are symmetricly set in the two ends of described interior ring outer wall.
Described snap ring be shaped as C shape, two opening end is bent inwardly into hook-type.
Described snap ring is made by Stainless Steel Wire.
Technique effect of the present utility model is: the utility model forms the Balanced Current structure by snap ring and cooperating of bearing outer ring and inner ring, prevent to produce electric discharge phenomena because of potential difference, avoid the electro erosion that produces in the bearing enclose raceway or drunk the burning phenomenon, guaranteed the stable performance of bearing; The cross section of groove is a V-type, can be better fixing snap ring, prevent that snap ring from dropping out from groove; The height of the outside trough rim of V-type groove is lower than the height of its inside slot edge, is easy to install snap ring; Snap ring is made by Stainless Steel Wire, and electric conductivity is better, can not produce the surfacial spalling thing because of getting rusty, thereby influences the life-span of bearing.

Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the A place enlarged view among Fig. 1;
Fig. 4 is the structural representation of the snap ring in the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As Fig. 1～shown in Figure 3, the utility model is a kind of current balance type ball bearing that is used for steering column for vehicles, comprises outer ring 1, inner ring 2, steel ball 4 and retainer 5, and outer ring 1 and inner ring 2 are fixing after by steel ball 4 and retainer 5 riveteds.The inwall of the utility model outer ring 1 is provided with circumferential first groove 7, the outer wall of inner ring 2 be provided with corresponding circumferential second groove, 6, the first grooves 7 in first groove, 7 positions and second groove 6 between be provided with snap ring 3.
As shown in Figure 4, snap ring 3 be shaped as C shape, two opening end is bent inwardly into hook-type, the snap ring 3 of this shape is an elastic structure.When snap ring 3 is installed, be to be pressed in the groove of outer ring 1 and inner ring 2, the ring body of snap ring 3 is stuck in first groove 7 of bearing outer ring 1; The hook-type of two opening ends of snap ring 3 both had been stuck in first groove 7 of bearing outer ring 1, was stuck in again in second groove 6 of bearing inner race 2, was fixed in the groove by the snap ring 3 outer tension force of elasticity own.This structure is different from the fixed structure of prior art middle (center) bearing seal ring, but simple installation, can be effectively fixing snap ring 3, prevent that snap ring 3 from dropping out from groove.
As shown in Figure 3, the cross section of first groove 7 and second groove 6 is preferably V-type.The V-type groove can be better fixing snap ring 3, prevent that snap ring 3 from dropping out from groove.
The height of the outside trough rim of V-type first groove 7 is lower than the height of its inside slot edge, and accordingly, the height of the outside trough rim of V-type second groove 6 is lower than the height of its inside slot edge.Design is easy to install snap ring 3 like this.
As shown in Figure 1, first groove 7 and second groove 6 can be arranged to one, also can be respectively arranged with two.Article two, first groove 7 is symmetricly set in the two ends of outer ring 1 inwall, and two second grooves 6 are symmetricly set in the two ends of inner ring 2 outer walls.Snap ring 3 can only be provided with one, between first groove 7 and second groove 6 of bearing one end; Also can be provided with two, lay respectively between first groove 7 and second groove 6 at bearing two ends.
Working principle of the present utility model is: when the rotatingshaft energising of steering column for vehicles is turned round, electric current flows through bearing inner race 2, snap ring 3 by contact matching is given outer ring 1 with current delivery, pass to steering column by outer ring 1 again, play a current reflux effect, it is suitable to reach the bearing enclose current value, thereby plays good current balance type effect.
The utility model by snap ring 3 with the cooperating of groove of bearing outer ring 1 and inner ring 2 form the Balanced Current structure, by the current value of equalizer bearing inner ring 2 with outer ring 1, thereby the current potential difference of control inner ring 2 and outer ring 1, prevent to produce electric discharge phenomena because of potential difference flashing point, avoid the electro erosion that produces in the bearing enclose raceway or drunk the burning phenomenon, guarantee the stable performance of bearing, can improve the working life of bearing, thereby improve the working life of automobile steering system, guarantee the safe in utilization of vehicle.
