Abstract

The invention discloses a method for generating real tooth surface of arc tooth surface gear based on circular arc tooth profile, which comprises the following steps: firstly, determining model parameters of arc tooth surface gear and arc tooth generating rack; 2, establishing a spatial coordinate system according to that relative motion relation among the arc tooth produce rack, the arc tooth cylindrical gear and the arc tooth surface gear; 3, based on that tooth profile of the arc, establishing the tooth profile equation of the arc tooth generate rack; 4, deriving that equation of circular arc tooth profile arc tooth surface gear by the coordinate transformation method; 5, solving the meshing equation according to the conjugate meshing process of the simulated arc tooth cylindrical gearand the arc tooth surface gear; 6, calculating the tooth surface point cloud of the arc tooth surface gear through digital programming, and obtaining a three-dimensional model of the arc tooth surfacegear through array fitting. The utility model has the advantages of large coincidence coefficient of the tooth shape, stable and reliable transmission, strong bearing capacity, and can meet the transmission requirements under extreme conditions.

Description

Technical field [0001] The invention relates to a novel gear modeling technology, and mainly relates to a method for creating a true tooth surface of an arc tooth surface gear based on an arc tooth profile, and belongs to the technical field of gears. Background technique [0002] The arc tooth profile curved surface gear is an innovation of the tooth profile and tooth profile on the basis of the traditional straight tooth surface gear. It aims to improve the gear transmission performance, meshing degree, overlap coefficient and load-bearing capacity. It can become a new type of surface gear in the future. One of the development paths. With the rapid development of computer technology, relying on computer-aided design means can fully broaden the scope of gear visual design, but the development field of large-scale modeling software popular on the market has not fully covered some special parts fields. The method of the present invention is aimed at For some problems that are dif...
