Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
As shown in Figure 1, in the present embodiment, the loss of weight pin roller bearing retainer 11 possessing cascade annular side circle and hollow pin provided by the invention, comprises a pair cascade annular side circle 12 and some hollow pin 13.End for the hollow pin of rotary support rolling element is assemblied in the pin attachment hole 14 in annular side circle.Annular side circle is integral type, stepped, comprises thin plate 15, strengthening rib 16, pin attachment hole 14 and pin attachment hole boss 17.Described strengthening rib 16 connects described thin plate 15, in step-like between described strengthening rib 16 and described thin plate 15; Described pin attachment hole boss 17 is arranged on described thin plate 15; Described pin attachment hole 14 runs through described pin attachment hole boss 17 and described thin plate 15.
