Embodiment 1

[0027] The present embodiment provides a kind of lubricating grease for robots, comprising the following components: in terms of mass fraction, 80% of base oil, 5% of lithium complex soap thickener, antioxidant (mass ratio is 1:1.3 diphenylamine and 2 , 6-di-tert-butyl p-cresol) 3%, extreme pressure antiwear agent (thiadiazole derivatives, molybdenum phosphate and triphenyl phosphate with a mass ratio of 3:25:5) 3%, solid lubricant ( α-zirconium phosphate) 2% and complex calcium sulfonate base grease 7%; the base oil is a mixture of hydrogenated base oil, PAO8 and diisobutyl phthalate in a mass ratio of 1:3:1.

[0028] Mix the hydrorefined base oil, PAO8 and methyl phthalate evenly and add it to the complex lithium soap, then add the antioxidant, extreme pressure anti-wear agent, solid lubricant, and calcium sulfonate complex grease respectively. Grinding and dispersing with a three-roll mill to obtain finished grease.

Embodiment 2

[0030] The present embodiment provides a kind of lubricating grease for robots, comprising the following components: in mass fraction, base oil 85.7%, lithium complex soap thickener 6%, antioxidant (mass ratio is 1:1 diphenylamine and 2 , 6-di-tert-butyl p-cresol) 1%, extreme pressure antiwear agent (thiadiazole derivatives, molybdenum phosphate and triphenyl phosphate with a mass ratio of 1:3:2) 2.3%, solid lubricant ( gamma-zirconium phosphate) 1% and complex calcium sulfonate base grease 4%; the base oil is hydrorefined base oil, PAO10 and triisotridecyl trimellitate ( TMTT) mixture.

[0031] The preparation method is the same as in Example 1.

Embodiment 3

[0033] The present embodiment provides a kind of lubricating grease for robots, comprising the following components: in mass fraction, base oil 78%, lithium complex soap thickener 6%, antioxidant (mass ratio is 1:2 diphenylamine and 2 , 6-di-tert-butyl p-cresol) 2%, extreme pressure antiwear agent (thiadiazole derivatives, molybdenum phosphate and triphenyl phosphate with a mass ratio of 1:5:2) 4%, solid lubricant ( τ-zirconium phosphate) 2.5% and complex calcium sulfonate base grease 7.5%; the base oil is a mixture of hydrorefined base oil, PAO10 and triethylol propane ester with a mass ratio of 3:3:1.

[0034] The preparation method is the same as in Example 1.

Abstract

The invention relates to a lubricating grease and its application in a robot harmonic reducer. The lubricating grease comprises the following components: by mass fraction, 78-86% of base oil, 5-8% of thickener, anti-oxidant 1-3% of anti-wear agent, 2.3-4% of extreme pressure anti-wear agent, 1-3% of solid lubricant and 4-8% of complex calcium sulfonate base grease; the mass ratio of the base oil is 2-6:6:1 ~2 mixture of mineral oil, PAO synthetic oil and ester oil. The lubricating grease of the invention has good mechanical stability, extreme pressure anti-wear performance, high temperature stability, oxidation stability, low temperature resistance performance and fretting wear resistance performance.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a lubricating grease for robots and its application. Background technique [0002] Grease is a thick grease-like semi-solid, which is used for the friction parts of machinery to lubricate and seal. Grease can be divided into general grease and special grease, the former is used for general mechanical parts, and the latter is used for tractors, railway locomotives, ship machinery, oil drilling machinery, valves, etc. With the development of science and technology and the advancement of automation technology, the application fields of industrial robots are becoming wider and wider. Industrial robots are mainly composed of three core components: reducer, servo motor and control system. Precision reducer is the most critical function in industrial robots. Components are also one of the bottlenecks currently restricting the development of my country's robot industry. Due to the high cost of...
