A method for testing the heat transfer performance of lubricating grease for rv reducers

Abstract

The invention discloses a detection method for the heat transfer performance of lubricating grease for an RV reducer. The detection method comprises the steps that a, the lubricating grease is smeared on the RV reducer; b, after installation, one position of the RV reducer is selected for temperature imaging shooting; c, an instrument is selected for temperature testing; d, according to the test result, software is selected for analysis, and the average temperature T1 of the test surface is calculated; e, running is carried out for a period of time before being stopped, the temperature testing instrument is used for performing temperature testing on the same surface, the test result is analyzed through temperature distribution processing software, the average temperature T2 of the test surface is calculated, and the temperature rise rate R is calculated according to the equation: R=(T2-T1) / T1; f, the standard empirical temperature rise rate RT of the heat transfer performance is determined; g, the heat transfer performance is detected according to the evaluation index i which is equal to R / RT. Through the detection method, the test result is simpler, more convenient to obtain and scientific, and the evaluation result is more persuasive. Meanwhile, the method has the advantages that accuracy is high, and errors are small, and the method can also be popularized to relevant fields.

Description

technical field [0001] The invention relates to the field of evaluating the thermal conductivity of industrial lubricating grease, in particular to a method for detecting the thermal conductivity of lubricating grease for an RV reducer. Background technique [0002] In recent years, China has become the world's largest robot market, and it is expected to grow at a relatively high rate in the next few years. As a high-precision reduction transmission device for industrial robot systems, RV reducers play a key role in the industrialization of industrial robots. During the working process of the RV reducer, a large amount of heat is generated due to friction. If the heat cannot be dissipated quickly, it will cause heat to accumulate on the friction surface, which will cause the service life of the RV reducer components to decrease. Therefore, the special lubricating grease used in the RV reducer needs to be continuously improved and broken through, and try to avoid the reducti...
