Abstract
The utility model relates to a lockable spilt cage, which comprises a circular frame body, wherein more than five roller pockets are uniformly distributed at the circumference of the circular frame body; pocket beams are arranged between the adjacent roller pockets; one of the pocket beams on the circular frame body is provided with an opening in the middle; one end plane of the opening of the circular frame body is provided with a groove in the axial direction, the other end plane of the opening of the circular frame body is provided with a lug in the axial direction, and the lug is blocked and connected with the inside of the groove. A split face of the cage is formed into a lockable connecting structure; the stress situation of rollers in the split cage is improved; not only is the installation efficiency of a roller bearing kept, but also the noise generated by the roller bearing during the work process is reduced, and the service life of the rolling bearing is improved.
Description
Technical field
The utility model relates to a kind of lockable split type retainer, belongs to nonmetallic bearing retainer technical field.
Background technique
The roller bearing that is used in the automobile-used gearbox normally is installed between driving gear and the transmission shaft, roller bearing mainly is made of retainer and roller etc., retainer is made of along the uniform plurality of rollers pocket hole of circumferential surface annular frame and annular frame, roller is installed in each roller pocket hole, contacts with transmission shaft with driving gear respectively by roller.And its bearing inner race of the roller bearing of another kind of structure is connected with retainer, and bearing inner race is installed on the transmission shaft, and roller is installed in the mounting hole of driving gear.Common retainer is an overall structure, and therefore comparatively difficulty of roller is installed.For improving installation efficiency, mostly adopt at present the retainer of split type structure, the middle part of a pocket hole lintel of retainer is provided with opening as split surface, because of retainer is made by nonmetallic material, so utilize the resiliently deformable of retainer itself, very convenient when roller is installed, solved the inefficient problem of Bearing Installation.But when the roller bearing of this structure is installed in the gearbox, because the split surface of retainer does not form connection, the split surface of retainer exists certain clearance, retainer distortion occurs and forms oval, this makes the central position in each the roller pocket hole on the retainer change again, the oscillation space that makes roller and match between axle or the mounting hole increases, roller bearing during work is under gravity and action of centrifugal force, after roller is subjected to impact force, the variation meeting of the movement locus of roller impacts to transmission shaft or driving gear, and the resistance to motion of increase roller makes the frictional force of roller bearing increase, and causes heating and the working life of shortening roller bearing.Moreover, because roller is in rotation process,, the mobile meeting of roller and transmission shaft or driving gear produce noise because of impacting, the opening of the split surface on the retainer also can collide and can produce noise in addition.
Summary of the invention
The utility model is the deficiency that overcomes above-mentioned technology, provides a kind of and can improve the force-bearing situation of roller in the split type retainer, reduces the lockable split type retainer of noise.
The utility model is the technological scheme that achieves the above object: a kind of lockable split type retainer, comprise annular frame, annular frame is evenly equipped with roller pocket hole more than five along circumferential surface, has pocket hole lintel between adjacent each roller pocket hole, the middle part of one of them pocket hole lintel is provided with opening on the described annular frame, it is characterized in that: an end face of described annular frame opening is provided with groove vertically, and the other end of annular frame opening is provided with projection vertically, and projection is connected in the groove.
The utility model is provided with groove vertically at an end face of annular frame opening, and the other end of annular frame opening is provided with projection vertically, projection on annular frame one end face is connected in the groove on the other end, make the linkage structure of the split surface formation lockable of retainer, when the assembling roller, retainer is that opening-wide state produces, the installation roller is convenient and swift, and after with the assembling of retainer and roller, because the connection of split surface can not deform retainer, so roller rotates in roller pocket hole and can not be moved, roller bearing is under gravity and action of centrifugal force in the work, oscillation space between roller and transmission shaft that matches or the mounting hole reduces, reduce the collision of roller and gear mounting hole or transmission shaft, improve the stressing conditions that is installed in roller in the split type retainer, also can reduce the roller bearing kinetic friction force, can improve the working life of roller bearing.On the other hand, because the split surface of retainer is a linkage structure, so split surface can not produce collision and produce noise yet, simultaneously because of having reduced the amount of movement of roller, reduced the noise of roller bearing yet.

Embodiment
Shown in Fig. 1～3, the utility model lockable split type retainer, comprise annular frame 1, annular frame 1 is evenly equipped with roller pocket hole 2 more than five along circumferential surface, has pocket hole lintel 3 between adjacent each roller pocket hole 2, the retainer of roller bearing adopts engineering plastics to make, the middle part of one of them pocket hole lintel 3 is provided with opening 4 on the annular frame 1, make retainer form half subdivision structure, this opening 4 also is the split surface of retainer, and an end face of annular frame 1 opening 4 is provided with groove 5 vertically, and the other end of annular frame 1 opening 4 is provided with projection 6 vertically, and projection 6 is connected in the groove 5, makes retainer form the linkage structure of a lockable.
See shown in Figure 3, groove 5 on 4 one end faces of the utility model annular frame 1 opening is interior big young curve bath, and the projection 6 on another end face of annular frame 1 opening 4 is front wide and rear narrow cylindricality, on this annular frame 1 projection 6 of cylindricality pass annular frame 1 other end curve bath notch and enter in the curve bath, make the both ends of the surface clamping at annular frame 1 opening 4 places, and form complete retainer.
The utility model can also be that the groove 5 on 4 one end faces of annular frame 1 opening is the hook-type notch, and projection 6 its front portions on another end face of annular frame 1 opening 4 have coupler body, coupler body on 1 one end faces of this annular frame is connected in the hook-type notch of its another end face, the both ends of the surface clamping at shape support body 1 opening 4 places of giving a piece of bad advice, and form complete retainer.
