Processing parameter optimization method for reducing mounting error sensitivity of hypoid gear

Abstract

The invention discloses a machining parameter optimization method for reducing the mounting error sensitivity of a hypoid gear. The method comprises the following steps of: giving geometric parametersof the gear blank of the large gear, size parameters of the gear cutter and machining parameters of a machine tool; after geometric parameters of the small gear blank and size parameters of the gearcutter are given, establishing an installation error comprehensive sensitivity optimization model, finding out the optimal machining parameters of the small gear machine tool through a genetic algorithm, and therefore reudicng the sensitivity of the hypoid gear pair to the installation error. According to the method, the degree of influence of different types of installation errors on the meshingperformance can be judged, so that a theoretical basis is provided for assembly precision control during actual installation.

Description

technical field [0001] The invention relates to a method for optimizing machine tool processing parameters of hypoid gears, in particular to a method for optimizing machine tool processing parameters for reducing the sensitivity of meshing quality of hypoid gears to installation errors. Background technique [0002] Due to the advantages of large reduction ratio and small size, hypoid gears are often used in mechanisms with large loads and high speeds, and have high requirements for smooth and quiet operation. The good vibration and noise characteristics of the gear pair are closely related to the ideal meshing performance of the tooth surface, and the meshing performance is jointly affected by the microscopic morphology of the tooth surface, the gear cutting process, and the assembly accuracy. At present, the tooth surface shape design and gear cutting process have reached a relatively high level, but how to effectively reduce the impact of installation errors on meshing pe...

Problems solved by technology

[0004] The above studies on the influence of installation errors on the meshing performance of hypoid gears or spiral bevel gears are all based on the research on the influence of installation errors on the meshing performance of gear pairs. Therefore, it is impossible to compare the influence of different types of installation errors on the meshing performance of gear pairs, and it is not possible to propose a practical method to reduce the sensitivity of hypoid gears to installation errors. Therefore, there are still deficiencies in engineering practical applications.
