With the development of numerical calculation methods, the finite element method (FEM) has been widely used in engineering analysis. It is also an important part of computer-aided manufacturing and computer-aided analysis. At present, the finite element method is widely used in the strength analysis and stiffness analysis of hypoid gears, and it has become an important tool and means for the analysis of hypoid gears through computer simulation.
Tooth strength analysis is to simulate the whole process of gear pair meshing by computer, record the changes of each process, and obtain valuable information. These work provide basic judgment basis for the design and manufacture of hypoid gears, and also provide better and more accurate parameters for the adjustment of gear cutting machine tools.
The meshing part of the hypoid gear is a local point contact and conjugate meshing mode. The experts of Gleason company studied the contact process of the hypoid gear and put forward the tooth surface contact analysis. This analysis method does not consider the influence of external load and tooth deformation, and the analysis result has a large error, which is often inconsistent with the actual situation.
Later, the tooth surface contact analysis was developed into the loaded contact analysis. Scientists put forward the method of tooth loading contact analysis, and on this basis, developed the corresponding analysis software, i.e. loaded tooth surface meshing analysis, referred to as LTCA. The analysis results are very accurate and reliable. It provides a basic basis for the design and manufacture of hypoid gears, and is of great significance.
Now, the load contact analysis of gear teeth has attracted great attention at home and abroad. Many countries have carried out research in this area and achieved some results. In the research field of hypoid gears, this technology is a bridge connecting geometric design and mechanical analysis, and its research results have very important guiding significance.
