Abstract

The invention discloses a gear transmission device plated with a super-lubricating solid film. The gear transmission device is composed of a gear transmission device body and an a-C: H-based super-lubricating solid film plated on one surface or two surfaces of a gear meshing surface. A conductive threaded hole is formed in a coating part and is used for being communicated with the conductive areaof a processing platform through a conductive screw during preparation. According to the device, the operation friction torque can be greatly reduced through coating, the rotation stability is improved, and the energy loss is reduced; and the addition of the threaded hole for electric conduction can also ensure the electric conduction between the coating part and a workbench during processing.

Description

technical field [0001] The invention belongs to the technical field of bearings, and relates to a gear 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 appli...
