Abstract
The utility model discloses an elastic ring for a rubber bearing. The elastic ring is in a structure of a V-shaped groove with an opening, the included angle of the V-shaped groove is 90 degrees, and the elastic ring is made of SK5 spring steel. According to the elastic ring for the rubber bearing, abnormal sounds and jumping generated on the opening when the bearing works can be eliminated, rotation of a steering gear box of a steering column is stable and little in shaking, and meanwhile service life of the bearing is prolonged.
Description
Technical field
The utility model relates to bearing processing design field, particularly relates to a kind of employed elastic ring of elastic caoutchouc needle bearing that is used for.
Background technique
At the employed elastic ring of elastic caoutchouc needle bearing, be generally low-carbon steel material in the existing technology, undercut groove is the skewed slot of 45 degree, and carries out carbonitriding heat treatment.Its shortcoming is, 45 degree skewed slots make elastic ring upper shed zone big, and heat treatment deformation is serious, causes needle roller and elastic ring bad connection, is prone to bearing and rotating the abnormal sound and the problem of beating of producing.Simultaneously the wear resistance of used low-carbon steel material is relatively poor relatively, influences bearing working life.
The model utility content
The technical problem that the utility model mainly solves provides a kind of rubber bush bearing and uses elastic ring, can eliminate the rotation abnormal sound and the problem of beating that bearing exists, the working life of improving bearing.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of rubber bush bearing to use elastic ring, said elastic ring is the V-type groove structure of an opening, and the angle of said V-type groove is 90 degree; V-type groove shape on the elastic ring circumference shortens the open area girth, makes elastic ring and needle roller that the excellent contact line arranged, and the distortion of product when heat treatment is little and improved the poor contact phenomenon with needle roller; Said in addition elastic ring material is the SK5 spring steel, behind the SK5 spring steel Q-tempering higher hardness and wear resistance is arranged, and has improved the wear resistance of needle roller simultaneously.
The beneficial effect of the utility model is: the V-type groove structure that the utility model adopts; The life-span of elastic caoutchouc bearing is improved; Abnormal sound during bearing rotates simultaneously significantly reduces with beating, and has improved the total quality of elastic caoutchouc needle bearing, has reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the utility model rubber bush bearing with elastic ring one preferred embodiment.
The mark of each parts is following in the accompanying drawing: 1, elastic ring; 10, V-type groove.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the utility model is embodiment comprise: a kind of rubber bush bearing is with elastic ring 1, V-type groove 10 structures that said elastic ring 1 is an opening, and the angle of said V-type groove 10 is 90 degree.
Further, rubber bush bearing as shown in Figure 1 is with elastic ring 1, adopts the SK5 spring steel to be made, and product carries out hardness and wear resistance raising after the Quenching Treatment, is assemblied on the elastic caoutchouc needle bearing, and is big with the area of contact of needle roller, rub resistance.
The utility model rubber bush bearing is different from existing technology with elastic ring: 90 degree V-type groove elastic rings are compared and traditional skewed slot hatch frame; Circumference upper shed section length has reduced half the, and the integral installation distribution structure is optimized more, and the heat treatment deformation amount reduces; Make needle roller have the excellent contact face at opening; Reduced the abnormal sound and the quality problems of beating in the bearing rotation, it is higher than using low carbon steel to have wear resistance to adopt the SK5 spring steel to do material simultaneously, the working life of also having improved bearing.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
Claims (2)
1. a rubber bush bearing is used elastic ring, it is characterized in that: said elastic ring is the V-type groove structure of an opening, and the angle of said V-type groove is 90 degree.
2. rubber bush bearing according to claim 1 is used elastic ring, it is characterized in that: said elastic ring material is the SK5 spring steel.
