Problems solved by technology

[0002] Most industrial robots are used for handling and welding operations, and play a vital role in the service industry. The reducer at the joint is the key mechanism for completing the work. Due to its working conditions and working temperature, boundary lubrication is easy to occur. Fretting wear and long grease cycle, therefore, this field needs grease with long service life and wear resistance to ensure the long-term operation of the robot

Abstract

The invention provides an industrial robot joint speed reducer lubricating grease and a preparation method thereof. The industrial robot joint speed reducer lubricating grease comprises, by weight, 5-20 parts of a thickener, 0.5-3 parts of an antirust agent, 0.5-5 parts of an anti-oxidation antiseptic, 0.5-5 parts of an extreme pressure antifriction agent and 75-95 parts of synthetic hydrocarbon base oil. The industrial robot joint speed reducer lubricating grease has the advantages of good high and low temperature lubricity, good oxidation and corrosion resistance, reduction of the antifriction property and the anti-fretting wear property, and prolongation of the service life of industrial robots.

Description

technical field [0001] The invention belongs to the field of lubricating grease, and in particular relates to a lubricating grease for an industrial robot joint reducer and a preparation method thereof. Background technique [0002] Most industrial robots are used for handling and welding operations, and play a vital role in the service industry. The reducer at the joint is the key mechanism for completing the work. Due to its working conditions and working temperature, boundary lubrication is easy to occur. Fretting is worn out and the lubricating grease cycle is long. Therefore, the field needs lubricating grease with long service life and wear resistance to ensure the long-term operation of the robot. Contents of the invention [0003] In view of this, the present invention aims to propose a lubricating grease for joint reducers of industrial robots and a preparation method thereof, which can ensure the normal operation of industrial robots for a long time under harsh w...
