Abstract
The utility model discloses a cylindrical roller bearing integral retainer, which is an integrated structure, and has a S-shaped curve. A hole (3) is cylindrical; a locking point (6) and a locking point (7) capable of locking the roller in the vertical direction are respectively arranged on inner diameter (4) and outer diameter (5) of the hole; and a conical aperture (8) with an angle (alpha) is disposed on the bottom of the hole (3). The utility model improves the bearing assembling performance, has advantages of smooth operation, good reliability, small friction coefficient and convenient dismounting and repairing, and greatly prolongs the service life of the bearing.
Description
Technical field
The utility model belongs to a kind of retainer, relates generally to a kind of structural type of roller bearing integral cage.
Background technique
At present, roller bearing integral cage structure has: pulling eye retainer, two halves riveted joint retainer, pillar welding retainer and nylon cages pattern, all there is certain deficiency in the said structure retainer.
1, pulling eye retainer: the processing method of broaching tool pulling eye is adopted in retainer pocket hole, and roller is packed into, and both sides cutter seal pins roller behind the pocket hole, and the size that the dynamics of cutter seal and the degree of depth directly influence pocket hole hold depth.Hold depth is the stuck roller of senior general too, and hold depth too Xiao Yi is fallen roller.
2, two halves riveted joint retainer: this structure retainer only is fit to medium and small bearing, and for extra large size bearing, the processing technology difficulty during its riveted joint is big, and riveting quality is poor.
3, pillar welding retainer: weld seam is easy to crack, causes bearing to lose efficacy in advance.
4, nylon cages: be not suitable for heavy duty, applying working condition that temperature variation is big, working life short, poor reliability.
Summary of the invention
The purpose of this utility model provides a kind of roller bearing integral cage, it can improve the assembly performance of bearing, remedy the deficiency of old structure, had reliability height, long service life, friction factor is little, running is steady, be beneficial to dismounting and characteristics such as maintenance.
The purpose of this utility model can adopt following technological scheme to realize: described retainer is the integrity structure, the whole S-shaped curvilinear structures of retainer, and the pocket hole is cylindrical, has the lock point that can pin roller up and down on pocket hole internal diameter, external diameter respectively; The bottom in described pocket hole is provided with the cone shape hole that has angle.
The beneficial effects of the utility model are: integral cage assembly performance described in the utility model is good; Sigmoid curve structural type makes things convenient for the roller pocket hole of packing into from two ends, the retainer left and right sides, has reduced the difficulty of retainer processing technology and assembly technology; Cylindrical pocket hole, but maximum area contains the rolling surface of roller, thus realize that bearing turns round safely and smoothly; Lock point on the inside and outside footpath, pocket hole can pin the roller in the retainer pocket hole of packing into up and down, and the bearing rotation flexibly, controlled the sag of chain of retainer simultaneously again, makes the contact of retainer discord lasso rib produce friction, has reduced frictional force and noise; The cone shape hole of pocket hole bottom band α angle both can store a certain amount of lubricating grease, and both lubricates has reduced the area of contact with roller end face again, therefore greatly reduces by fricative heating.In sum, the utility model has improved the assembly performance of bearing, have running steadily, good reliability, friction factor be little, be beneficial to characteristics such as dismounting and maintenance, prolonged the working life of bearing greatly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the A-A view of Fig. 1.
Accompanying drawing 3 is a pocket hole structure schematic representation.
Among the figure: 1, left end, 2, right-hand member, 3, the pocket hole, 4, internal diameter, 5, external diameter, 6, the lock point, 7, the lock point, 8, cone shape hole.
Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
Shown in accompanying drawing 1,2: described retainer is an overall structure, and the whole S-shaped curvilinear structures of retainer can make things convenient for roller from retainer left end 1 and the right-hand member 2 pocket hole 3 of packing into, has reduced the difficulty of retainer processing technology and assembly technology; Pocket hole 3 is cylindrical, is respectively arranged with lock point 6 and lock point 7 on pocket hole 3 internal diameters 4 and external diameter 5, can pin the roller in the retainer pocket hole 3 of packing into up and down.
As shown in Figure 3: 3 bottoms, pocket hole are provided with the cone shape hole 8 of band angle [alpha], both can store a certain amount of lubricating grease, and both lubricates has reduced the area of contact with roller end face again, therefore greatly reduces by fricative heating.
Claims (1)
