Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show a mode of execution of a kind of roller type backstop bearing of the present invention.The present invention includes by overcoat 1 and rotor seat 2 and be nested with the circumferential body of forming, a side of circumferential body is provided with a location cover plate.
The past periphery direction of the interior ring edge of rotor seat 2 deeply is formed with the containing groove 26 of a plurality of arranged spaced, and an end of containing groove 26 oblique peripheries is provided with spring stop surface 27.Dispose roller 23 and spring 24 in each containing groove, an end of spring 24 supports and terminates in described spring stop surface 27, and the other end of spring supports and terminates on the roller 23.
Overcoat 1 inner ring is provided with polygonal interior ring edge 11; Rotor seat 2 is provided with polygonal outer ring edge 21, and outer ring edge 21 matches with described interior ring edge 11.Containing groove is arranged on outer ring edge 21 inboards of rotor seat.
