Abstract

The invention relates to a method for optimizing the transmission efficiency of a speed reducer. The method comprises the following steps of: 1, proposing the transmission efficiency of the speed reducer and each power loss expression; 2, extracting structure parameters and working condition parameters which can be used for optimizing the transmission efficiency of the speed reducer; 3, establishing a speed reducer transmission efficiency simulation analysis model, analyzing the relation between the structure parameters and the working condition parameters extracted in the step 2 and the transmission efficiency, and selecting at least five parameters with the maximum influence as optimal parameters of an orthogonal test; and step 4, optimizing the transmission efficiency of the speed reducer through design of an orthogonal test scheme, simulation analysis and optimization result evaluation, and finally obtaining an optimal parameter combination meeting evaluation requirements. According to the method, influence factors are comprehensively considered in the whole optimization process, the actual operation condition is better met, the application range is wide, the method is not limited to speed reducers of specific structures, and in other words, the transmission efficiency can be greatly improved through the optimization method for speed reducers of different structures.

Description

technical field [0001] The invention relates to a method for optimizing the transmission efficiency of a reducer, and belongs to the technical field of reducers. Background technique [0002] As an important part of mechanical equipment, reducer is widely used in construction, vehicles, ships, aerospace and mining and other fields. In recent years, the rapid development of my country's industry has promoted rapid economic growth, but with it comes Severe environmental pollution and energy shortage problems, in order to solve this fundamental problem, it is necessary to improve the energy-saving technology in industrial production. The improvement of the energy-saving level of the reducer in industrial production is mainly reflected in the improvement of its transmission efficiency. [0003] The transmission efficiency of the reducer is related to the power loss of the reducer, and the power loss reflects the energy loss of the reducer in the working process. The application ...
