This application relates to the technical field of gears, in particular to a method for judging the remaining life of a gear, which includes the following steps: obtaining a plurality of scrapped gears, measuring the wear amount of the scrapped gears, and judging the force form of the scrapped gears, according to the The amount of wear and the force of the scrapped gears are used to classify a plurality of scrapped gears, and a plurality of scrapped gears are selected under each classification as test gears, and the life-influencing factors of the scrapped gears under each classification are determined; The test gears under one category are subjected to the gear fatigue strength test respectively, and the remaining life of the test gear until the test gear fails is recorded; the functional relationship between the remaining life of the test gear under each category and the remaining life influencing factor is calculated Mode. Through this method, empirical formulas for calculating the remaining life of the gears are respectively established for different classifications of gears, and the remaining life of the gears can be obtained quickly, intuitively, conveniently and effectively in actual production according to the empirical formulas.
Description
technical field [0001] The present application relates to the technical field of gears, in particular to a method for evaluating the remaining life of gears. Background technique [0002] At present, the tooth surfaces of most of the decommissioned and judged gears are not damaged, and the degree of wear is generally light. According to the research results of gear fatigue strength and corresponding experience, these gears should be able to continue to be used. At present, there are no relevant standards or evaluation methods at home and abroad that can accurately estimate the remaining life of these gears that have been used to a certain extent. It is impossible to judge how long these gears can be used and whether they will cause production stoppage. Other gears and bearings have to be abandoned due to the risk of damage and production stoppage, resulting in a great waste of resources and high maintenance and spare parts costs. Contents of the invention [0003] The pur...
