Abstract
The invention discloses an elastic ring for a rubber bearing. The elastic ring is in a V-shaped groove structure with an opening, an included angle of the V-shaped groove is 90 degrees, and materials of the elastic ring adopt SK5 spring steel. Through adopting the mode, the elastic ring for the rubber bearing has the advantages that the abnormal sound and the jumping generated at the opening part in the work process of the bearing can be eliminated, so the rotation of a steering pipe post steering gear box is smooth, the vibration is small, and meanwhile, the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to bearing processing design field, particularly relate 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.
Summary of the invention
The technical problem that the present invention 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 present invention 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 invention has the beneficial effects as follows: the V-type groove structure that the present invention adopts, the life-span of elastic caoutchouc bearing is improved, the 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 rubber bush bearing of the present invention 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 preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises: 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.
Rubber bush bearing of the present invention 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 embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention 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 present invention.
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.
