Problems solved by technology

[0004] In the prior art, the analysis of gear contact usually uses classical mechanics, finite element, boundary element and other methods to establish a corresponding finite element model to analyze the strength of the gear, but the process of this method is too cumbersome, and for different gears It is necessary to establish different models and recalculate and analyze, and the grid division in the existing technology often uses the volume generated by the software, which has poor accuracy and low quality

Abstract

The invention discloses a finite element-based full parameterized gear meshing analysis method, which comprises the following steps that: a user interaction interface is established by using an ansys parameterized design language (APDL), the initial parameters of a gear is identified, parameters which influence the geometrical shape and material of the gear are confirmed, then a tooth profile is obtained based on an involute and a transition curve parameter equation, and a complete gear tooth profile and a three-dimensional gear solid model are generated; and then, APDL implementation of parameterized mapping grids is carried out, end faces are segmented, proper grid units are selected to generate a complete gear parameterized model, after the parameterized model is obtained, assembly and contact analysis of the two gears are considered, initial contact of the gears is defined, corresponding boundary conditions are applied, and finally solving is carried out to obtain gear meshing results required by tooth surface contact stress, contact slippage, von Mises stress diagrams, deformation diagrams and the like.

Description

technical field [0001] The invention relates to the field of gear transmission and finite element analysis, in particular to a full parameterized gear mesh analysis method based on finite element. Background technique [0002] Gear transmission is a kind of machine transmission used in machines, and it is also a main form of power and motion transmission between components. Traditional gear transmission is characterized by compact structure, accurate transmission ratio, wide range of transmission ratio variation, and high transmission efficiency. However, with the development of intelligent manufacturing technology and precision machining technology, traditional gear transmission cannot meet the requirements. As a new type of gear transmission, face gear is born in response to the situation. Face gear transmission can be regarded as a special bevel gear transmission, and its meshing form and characteristics are similar to those of bevel gears. Compared with other transmissi...
