Embodiment

[0023] Example 1-1~Example 1-6, Comparative Example 2-1~Comparative Example 2-6 and Comparative Example 3-1~Comparative Example 3-3, in Table 1~Table 3, the base oil viscosity is 40°C kinematic viscosity at mm 2 / S.

[0024] In the base oils shown in Table 1, dissolve the thickener according to the ratio shown in Table 1, heat up the solution with the thickener dissolved while stirring, and continue stirring at 100°C to 120°C for 60 minutes to disperse it evenly , continue to heat up to 200 ° C ~ 220 ° C, keep the temperature for 10 minutes and then cool down, and homogenize three times with three rollers to form a base grease. Add compound additives to it according to the compounding ratio shown in Table 1, and then stir at 100°C to 120°C for 60 minutes. Then it was cooled, homogenized with triple rollers, and degassed to obtain a grease composition.

[0025] In half of the base oils shown in Table 2, dissolve 4,4-diphenylmethane diisocyanate (hereinafter referred to as MD...

Abstract

The invention relates to a lubricant composition for a RV speed reducer of a robot, and relates to the speed reducer with a rolling part and a sliding part operating together, in particular to lubrication of joint parts of an industrial robot. The lubricant composition is a lubricating grease composition which is formed by compounding an additive with base grease containing base oil and a thickening agent, wherein the base oil is one or more selected from the group consisting of a secondary hydrogenation base, poly-alpha olefin oil, alkyl naphthalene, ester oil and ether oil; compound fatty acid soap is one or more selected from the group consisting of lithium stearate, calcium stearate, polyhydroxy fatty acid lithium and polyhydroxy fatty acid calcium; the compounding proportion of the compound fatty acid soap is 3-10 parts by weight relative to 100 parts by weight of the base grease; and the compounding proportion of the additive is 4-13 parts by weight relative to 100 parts by weight of the base grease. The lubricant composition for the RV speed reducer of the robot provides effective initial abrasion and long-acting abrasion resistance, provides load resistance protection and meets the requirement for high-precision long-period operation of the robot.

Description

technical field [0001] The invention relates to a lubricant composition for a robot RV reducer, relates to a reducer in which a rolling part and a sliding part operate together, and in particular relates to the lubrication of joint parts of an industrial robot. Background technique [0002] According to the statistics of Gaogong Robotics, in the cost of industrial robots, reducers account for the highest proportion, accounting for 33% to 38%, servo systems account for 20% to 25%, and controllers account for 10% to 15%. . The reducer is an important cost component of the robot. Its operating life and accuracy are related to the actual service life of the entire robot. Therefore, the lubrication of the reducer is related to the entire life cycle of the robot. When lubricants with low load resistance are used to lubricate the joints on the robot, fatigue spalling often occurs on the shafts of the robot and members of the joints. The precision of the robot requires reducing we...
