Abstract
The utility model discloses a self-aligning roller bearing retainer. The self-aligning roller bearing retainer comprises a first retainer and a second retainer, wherein a ring-shaped groove is formed in a retainer base of the first retainer along one side opposite to a retainer beam on the first retainer; a ring-shaped boss which is matched and positioned with the ring-shaped groove is formed in the retainer base of the second retainer along one side opposite to the retainer beam on the second retainer; two cutting seams are respectively formed in each of the first retainer and the second retainer along the axial direction; the cutting seams in the first retainer and the second retainer are alternatively arranged; the first retainer and the second retainer are fixedly connected by a plurality of cylindrical pins and inner hexagonal bolts. The self-aligning roller bearing retainer disclosed by the utility model increases covering capacity of a rolling body, ensures that the rolling body stably rotates in a pocket hole of the retainer and prevents the rolling body from dropping out from the picket hole of the retainer. The integral retainer does not mutually contact and collide in operation, so that noise of a bearing during working is reduced, strength of the retainer is improved, premature fatigue damage of the retainer is avoided, and service life of the bearing is greatly prolonged.
Description
Technical field:
The utility model relates to a kind of aligning roller bearing retainer.
Background technique:
Existing selfaligning roller bearing wherein one type structure as shown in Figure 1, it comprises outer ring 1, inner ring 2, rolling element 3 and retainer 4, wherein retainer 4 is copper retainers that two body structures are identical.When the retainer of this kind of structure is used for the bearing of wide thin dimension series, the internal diameter size of its outer ring is little, due to the restriction of installing, cause the external diameter of retainer very little, therefore the containing amount of rolling element diminishes, bearing is in operation process, and rolling element can not smooth rotation in retainer pocket hole, and rolling element even can drop out from retainer pocket hole; Simultaneously two body retainers in bearing are on-stream is in contact with one another collision, causes the noise of bearing when work large; Because of the retainer thin thickness strength decreased for this kind of structure, make the in use retainer premature fatigue damage of its bearing again, cause bearing normally to use.
Model utility content:
The utility model is in order to make up the deficiencies in the prior art, a kind of aligning roller bearing retainer is provided, its reasonable in design, strengthened retainer outside dimension, thereby increased the containing amount of rolling element, bearing, in operation process, has guaranteed rolling element smooth rotation in retainer pocket hole, has avoided rolling element to drop out from retainer pocket hole; The retainer of integral type is on-stream can not be in contact with one another collision, has reduced the noise of bearing when work; Improve the intensity of retainer, avoided retainer premature fatigue to damage, greatly extended the working life of bearing, solved problems of the prior art.
The utility model is to solve the problems of the technologies described above adopted technological scheme to be:
A kind of aligning roller bearing retainer, comprise the first retainer and the second retainer, in the maintenance stand of the first retainer, along the relative side of the cage bar with on it, be provided with an annular groove, in the maintenance stand of the second retainer, along the relative side of the cage bar with on it, be provided with one and coordinate the annular boss of locating with annular groove, on the first retainer and the second retainer, be respectively equipped with vertically two joint-cuttings, the first retainer and relative being crisscross arranged of joint-cutting on the second retainer, several straight pins are fixedly connected with the first retainer with socket head screw with the second retainer.
Described socket head screw is located at the both sides of the joint-cutting of the first retainer and the second retainer.
The utility model adopts such scheme, and reasonable in design, has strengthened retainer outside dimension, thereby increased the containing amount of rolling element, bearing, in operation process, has guaranteed rolling element smooth rotation in retainer pocket hole, has avoided rolling element to drop out from retainer pocket hole; The retainer of the integral type being connected with socket head screw by straight pin is on-stream can not be in contact with one another collision, has reduced the noise of bearing when work; Improve the intensity of retainer, avoided retainer premature fatigue to damage, greatly extended the working life of bearing.

Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Fig. 2-7, a kind of aligning roller bearing retainer, comprise the first retainer 5 and the second retainer 6, in the maintenance stand of the first retainer 5, along the relative side of the cage bar with on it, be provided with an annular groove 7, in the maintenance stand of the second retainer 6, along the relative side of the cage bar with on it, be provided with one and coordinate the annular boss 8 of locating with annular groove 7, on the first retainer 5 and the second retainer 6, be respectively equipped with two joint-cuttings 9 vertically, joint-cutting 9 is divided into respectively two halves by the first retainer 5 and the second retainer 6, the staggered 90 ° settings relative to joint-cutting 9 on the second retainer 6 of the first retainer 5, what can make that the first retainer 5 is connected with the second retainer 6 is more firm, several straight pins 10 are fixedly connected with the first retainer 5 with socket head screw 11 with the second retainer 6.
Described socket head screw 11 is located at the both sides of the joint-cutting 9 of the first retainer 5 and the second retainer 6, can make joint-cutting 9 places of the first retainer 5 and the second retainer 6 be connected more firm.
Adopt aligning roller bearing retainer of the present utility model, reasonable in design, retainer 4 outside dimensions have been strengthened, thereby increased the containing amount of rolling element 3, bearing is in operation process, guarantee rolling element 3 smooth rotation in retainer pocket hole, avoided rolling element 3 to drop out from retainer pocket hole; The retainer of the integral type being connected with socket head screw 11 by straight pin 10 is on-stream can not be in contact with one another collision, has reduced the noise of bearing when work; Improve the intensity of retainer, avoided retainer premature fatigue to damage, greatly extended the working life of bearing.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
