Problems solved by technology

In addition, at present, there is no uniform standard or specification for robot-specific oil products to follow at home and abroad. Foreign companies keep secret the technology of special oil for industrial robot reducers, and the formulation technology of domestic robot-specific oil is still blank.

Abstract

The invention discloses a lubricating oil composition for an industrial robot speed reducer. The lubricating oil composition comprises 84.0-95.91wt% of polyalkylene glycol, 3-10wt% of a sealing applicability improver, 0.1-2.0wt% of an extreme pressure anti-wearing additive, 0.01-1.0wt% of a metallic deactivator, 0.05-1.0wt% of an anti-rusting corrosion inhibitor, 0.5-3.0wt% of an anti-oxidation additive and 10-20mu g / g of a defoaming agent, wherein the polyalkylene glycol is a linear polymer taking ethylene oxide and propylene oxide as main raw materials; the polymer comprises 50-70% of an EO(Ethylene Oxide) unit and 30-50% of a PO (Propylene Oxide) unit; the sealing applicability improver is a saturated polyol ester or diester. The lubricating oil composition has excellent viscosity-temperature performance and low-temperature performance, excellent oxidation stability and good extreme pressure wearing resistance, anti-rusting corrosion resistance and foam resistance, an oil film canbe rapidly formed, operation temperatures can be reduced, energy consumption can be reduced, the transmission efficiency of a speed reducer is degraded, the wearing of tooth surfaces can be reduced, and lubricating requirements of multi-stage speed reducers of multi-axis industrial robots can be met.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition used for a multi-stage reducer of an industrial robot, and belongs to the technical field of lubricating oil. Background technique [0002] Industrial robots are mainly composed of four major components: body, reducer, servo system and controller, among which the reducer is one of its core components, called "robot joints", which account for one-third of the overall cost of the robot and play a role The purpose of reducing the speed of the high-speed running power of the electric motor, internal combustion engine, etc. through the small gear on the input shaft and the large gear on the output shaft to reduce the speed and transmit greater torque. It is required to have the characteristics of short transmission chain, small size, high power, light weight and easy control. [0003] Special oil for industrial robot reducer is an important lubricating ma...
