ELASTIC ROLLER, PIN GEAR CYCLOIDAL SPEED REDUCER AND BEARING

WIPO Patent Application WO/2017/054409

A1

Disclosed are an elastic roller, a pin gear cycloidal speed reducer (100) provided with the elastic roller (51), and a bearing (3). The elastic roller (51) comprises a hollow roller (52) and a solid roller (53) provided on the inner side of the hollow roller (52). A floating gap allowing the hollow roller (52) to deform elastically is provided between an inner wall face of the hollow roller (52) and an outer wall face of the solid roller (53). The elastic roller (51) can provide a certain elastic deformation space for the hollow roller (52) by means of the floating gap so as to be able to realize a sufficient elastic compensation capacity when using an interference fit; at the same time, a certain support force can be supplied by the solid roller (53) on an inner side, preventing the hollow roller (52) from being flattened and destroyed due to excessive load, so that the elastic roller (51) has resistance to powerful overload impact, is relatively strong, and cannot be destroyed, so as to realize the purpose of reliable elastic compensation and further to increase the service life of the elastic roller, the pin gear cycloidal speed reducer and the bearing.
