Needle tooth cycloid speed reducer

Abstract

The invention provides a needle tooth cycloid speed reducer. The needle tooth cycloid speed reducer comprises a cycloid disc, a needle tooth shell, and a needle tooth component clamped between the cycloid disc and the needle tooth shell. The needle tooth component comprises multiple elastic rolling column combinations uniformly distributed in the peripheral direction of the inner side of the needle tooth shell. The elastic rolling column combinations comprise elastic rolling columns, and elastic elements clamped between the elastic rolling columns and the needle tooth shell in the radial direction of the needle tooth shell.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a pin-toothed cycloid reducer. 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 disc 3 at the same time, that is to say, there are so many needle teeth 2 that can bear force...

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
