Problems solved by technology

However, it has been proved that simply doing this cannot fully achieve the purpose, and the resulting high production cost also makes people doubt whether it can be truly commercialized in the future, so as to achieve the ability to compete with foreign products

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to an elastic roller with both flexibility and strength, a pin-toothed cycloid reducer with the elastic roller and a bearing. Background technique [0002] Pin-toothed cycloidal reducers have been widely used as transmission devices for industrial robots. In particular, the pin-toothed cycloid reducer represented by the RV reducer has become the most important part of the robot system due to its compact structure and strong transmission capacity. Please refer to figure 1 As shown, the RV pin cycloid reducer is mainly composed of pin gear housing 1, pin teeth 2, cycloid disc 3, eccentric shaft 4 and so on. The rotation of the eccentric shaft 4 drives the cycloidal disc 3, so that the cycloidal disc 3 performs a cycloidal motion on the needle teeth 2 to push the cycloidal disc 3 forward. Theoretically, there can be nearly 1 / 3 of the number of teeth 2 cooperating with the cycloid d...
