Abstract
The utility model discloses a self-locking structure holder mainly includes holder, pocket hole, bayonet socket, roller, has evenly seted up a plurality of pocket holes along the holder circumference, and every pocket hole all is separated by the bayonet socket, and the upper and lower opening size of two adjacent bayonet sockets all is less than the reducer diameter of roller for the roller can only be crowded into the pocket of holder downthehole through the bayonet socket outside, and can be at the downthehole free rotation of pocket. The utility model discloses a carry out redesign to the structure of holder, increased the bayonet socket structure, lock the roller into the pocket hole, when guaranteeing that the roller can freely normally rotate, can not deviate from the pocket hole again, do benefit to holder and roller moving as a whole, freely overturn. The production efficiency of the retainer product is integrally improved, the production cost is reduced, and the working pressure of assembly workers is reduced.
Description
Technical Field
The utility model relates to an automobile parts's field, concretely relates to auto-lock structure holder.
Background
In the prior art, a retainer of a tapered product is of an open structure, a roller and the retainer are separated, the roller can be freely separated from a pocket of the retainer, and the roller can be scattered by moving the retainer and a roller assembly; the retainer assembled with the rollers cannot realize free overturning of the retainer and the roller assembly due to scattering of the rollers under slight external force; the retainer and the roller assembly are sleeved by the inner ring to fix the roller, so that the retainer and the roller assembly without the inner ring are easy to scatter and need to be reassembled with the roller, and the roller can not be used any more if falling on the ground, thus the production and assembly of the retainer for the conical product are long in time consumption and high in cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a self-locking structure retainer.
The purpose of the utility model is accomplished through following technical scheme: the self-locking structure retainer mainly comprises a retainer, pocket holes, bayonets and rollers, wherein a plurality of pocket holes are uniformly formed along the circumference of the retainer, each pocket hole is separated by a bayonet, and the sizes of the upper opening and the lower opening of two adjacent bayonets are smaller than the diameter of the big end and the small end of each roller, so that the rollers can only be extruded into the pocket holes of the retainer through the outer sides of the bayonets and can freely rotate in the pocket holes.
The utility model has the advantages that: the rollers no longer fall out of the cage pockets; the bayonet structure is added, so that the rotation of the roller is not influenced; after the rollers are arranged, the retainer and the rollers can be randomly and integrally moved and freely turned over.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a schematic structural view of the cage and the rollers after mounting.
Description of reference numerals: cage 1, pocket 2, bayonet 3, roller 4.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawing, this kind of auto-lock structure holder, mainly include holder 1, pocket 2, bayonet socket 3, roller 4, a plurality of pocket 2 have evenly been seted up along 1 circumference of holder, every pocket 2 all is separated by bayonet socket 3, and the upper and lower opening size of two adjacent bayonet sockets 3 all is less than roller 4's reducer diameter, make roller 4 only can be crowded into in pocket 2 of holder 1 through the 3 outsides of bayonet socket, and can be in pocket 2 free rotation, but can not deviate from bayonet socket 3, assembled roller 4 and holder 1 form a whole like this, if not especially hard, roller 4 can not deviate from pocket 2 of holder 1.
The utility model discloses a carry out redesign to the structure of holder, increased the bayonet socket structure, lock the roller into the pocket hole, when guaranteeing that the roller can freely normally rotate, can not deviate from the pocket hole again, do benefit to holder and roller moving as a whole, freely overturn. The production efficiency of the retainer product is integrally improved, the production cost is reduced, and the working pressure of assembly workers is reduced. The utility model discloses practical application has first, two, the third generation tapered wheel hub units of single-row tapered roller bearing.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
