Description
Technical Field
The utility model relates to the technical field of bearing retainers, in particular to a sealing retainer for a thin-wall semi-rigid bearing.
Background
In the thin-wall semi-rigid bearing, only one half of the retainer is arranged in the bearing to guide the steel ball to run in the bearing; the ball loading of the retainer is to load a steel ball from an opening on the end face of the retainer and finally assemble the steel ball into the whole bearing; the size of the retainer locking opening with the structure influences the loading force of the steel ball, so that the proper design of the ball loading locking opening has great influence on the loading of the steel ball; the locking notch is too small, the steel ball is difficult to press in, the retainer is likely to deform greatly after being pressed in, and if the locking notch is too large, the retainer is easy to drop after the steel ball is pressed in; however, in the semi-rigid bearing, especially when the wall thickness is thin and the steel ball is small (less than 3mm), the retainer is easy to deform and fall off when receiving the cantilever load, so that the phenomenon of bearing jamming is caused.
SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model provides a sealing retainer for a thin-wall semi-rigid bearing, which comprises a frame body, wherein pockets are arranged on the frame body at intervals, first convex blocks are arranged on the inner wall of the frame body between the adjacent pockets and connected through first connecting blocks, the first connecting blocks are arranged along the edges of the pockets, the radian of the edges of the first connecting blocks is matched with that of the pockets, second convex blocks are arranged on the outer wall of the frame body between the adjacent pockets, one ends of the second convex blocks are connected through a second connecting block frame body, steps are formed at the other ends of the second convex blocks, the second connecting blocks are arranged smoothly, and the second connecting blocks extend towards the edges of the pockets.
The beneficial effect who so sets up is: according to the arrangement, the two sides of the retainer are sealed, so that the steel balls are completely wrapped in the pocket holes of the retainer, and meanwhile, the design of the convex blocks is added on the inner wall and the outer wall of the retainer, so that the strength of the retainer is increased; because the lug passes through the connecting block to be connected, when improving stability, make things convenient for cage pocket drawing die processing, the steel ball of also being convenient for more is packed into to increased the support area to the roller through lug and connecting block structure, make the roller difficult for deviating from, simple structure simultaneously, the production and processing of being convenient for has good result of use.
As a further arrangement of the utility model, the first connecting block is arranged at the lower edge of the frame body, and the second connecting block is arranged at the upper edge of the frame body.
The beneficial effect who so sets up is: set up like this for overall structure counter weight is more reasonable, improves overall structure's stability, and simple structure has good result of use simultaneously.
As a further arrangement of the present invention, one end of the first protrusion, which is far away from the second connection block, is arranged in an inclined plane.
The beneficial effect who so sets up is: set up like this, the overall structure's of being convenient for installation, it is more smooth and easy simultaneously to simple structure does benefit to the realization, has good result of use.
As a further arrangement of the present invention, the second protrusion is connected with the step through a smooth slope.
The beneficial effect who so sets up is: set up like this for overall structure installs more convenient smooth and easy, and structural stability is stronger, has better result of use.
As a further arrangement of the utility model, the side edges of the first convex blocks are attached to the edges of the two sides of the pocket.
The beneficial effect who so sets up is: set up like this for can overall structure be more inseparabler, the side through the lug increases the support to the ball simultaneously, improves the whole result of use of holder, and overall stability is stronger simultaneously.
As a further arrangement of the utility model, the side edges of the second convex blocks are attached to the edges of the two sides of the pocket.
The beneficial effect who so sets up is: set up like this for can overall structure be more inseparabler, the side through the lug increases the support to the ball simultaneously, improves the whole result of use of holder, and overall stability is stronger simultaneously.
