Abstract

The invention discloses a rolling transmission device plated with a super-lubricative solid thin film. The rolling transmission device is composed of a rolling transmission device body and the a-C:H based super-lubricative solid thin film plated on one face or two faces in rolling contact faces. Threaded holes used for electric conduction are formed in a film plating part and are used for communicating with an electric conduction area of a machining platform through electric conduction screws during preparation. According to the rolling transmission device, by means of film plating, the operation friction torque can be substantially reduced, rotation stability is increased, and the energy loss is reduced; and by adding the threaded holes used for electric conduction, electric conduction between the film plating part and the work table can be ensured during machining.

Description

technical field [0001] The invention belongs to the technical field of bearings, and relates to a rolling transmission device coated with a super-lubricating solid film. Background technique [0002] Super lubricating solid film and traditional solid lubricating film (such as MoS 2 ), its friction coefficient (<0.005) is 1-2 orders of magnitude lower, and the fluctuation of friction torque is greatly reduced, which can greatly improve the running stability of movable mechanisms, reduce friction torque and energy consumption, and is very important for improving the smooth operation of space spacecraft. It plays an irreplaceable important role in reducing the noise and power attenuation caused by friction. [0003] Although many universities and research institutes at home and abroad have conducted a lot of research on superlubricating materials and tried to prepare macroscopic superlubricating films, up to now, there is no superlubricating film that can be successfully ap...
