Plant spliced needle bearing cage.
This utility model solves its technical problem and be the technical scheme is that a kind of spliced needle bearing cage,
Bag retainer body, described retainer body is half retainer of two mutual splicings, if described half retainer is provided with the Heavenly Stems and Earthly Branches
Dagger, described support column is uniformly distributed along described half retainer circumference, and described support column sets away from one end of described half retainer
Having clamping joint, described half retainer is provided with bayonet socket between adjacent two support columns, and described bayonet socket matches with described clamping joint,
Between half retainer of two mutual splicings, the clamping joint correspondence on one of them half retainer is inserted on another retainer
In bayonet socket, it is spliced into a complete retainer by two half identical retainers, by supporting between two and half retainers
Clamping joint on post and the bayonet socket on half retainer cooperate to spacing and fix half retainer.
In order to make retainer fixation each other, further, described clamping joint is provided with two symmetries
The claw arranged, the outside of described claw is provided with pawl, and described bayonet socket is the two-stage shoulder hole being opened on half retainer, institute
Stating the thin segment of two-stage shoulder hole near described support column, described clamping joint is positioned at the thin segment of corresponding two-stage shoulder hole,
Described pawl is positioned at the thick section of described two-stage shoulder hole, and the step surface of described two-stage shoulder hole is against described pawl, by card
The agnail of joint upper clipping claw cooperates with two grades of shoulder holes in bayonet socket so that adjacent two and half retainers fix tightly each other
Gu it is reliable, it is ensured that retainer is the most reliable and the most stable.
The beneficial effects of the utility model are: the spliced needle bearing cage of this utility model, identical by two
Half retainer is spliced into a complete retainer, by the clamping joint on support column and half retainer between two and half retainers
On bayonet socket cooperate to spacing and fix half retainer, on half retainer of two mutual splicings between adjacent two support columns
Formation fenestra, this utility model simple in construction, easy to operate, firm and reliable connection, improve installation effectiveness, simultaneously when producing
Use the production that can complete retainer once secondary mould, reduce production cost.

Detailed description of the invention
Presently in connection with accompanying drawing, the utility model is described in more detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
Embodiment 1
As shown in Fig. 1,2,3,4 and 5, a kind of spliced needle bearing cage, bag retainer body 1, described retainer
Body 1 is half retainer 1-1 of two mutual splicings, and described half retainer 1-1 is provided with some support columns 2, described support column 2
Being uniformly distributed along described half retainer 1-1 circumference, described support column 2 is provided with clamping joint away from one end of described half retainer 1-1
3, described half retainer 1-1 are provided with bayonet socket 4 between adjacent two support columns 2, and described bayonet socket 4 matches with described clamping joint 3,
Between half retainer 1-1 of two mutual splicings, the clamping joint 3 on one of them half retainer 1-1 is corresponding inserts another holding
In bayonet socket 4 on frame 1-1, half retainer 1-1 of two mutual splicings forms between adjacent two support columns 2 fenestra 5.
Being provided with two symmetrically arranged claws 301 on described clamping joint 3, the outside of described claw 301 is provided with pawl
