Research On The Error Correcting Technology And Application Of Spiral Bevel And Hypoid Gears

In modern machinery, the spiral bevel and hypoid gears is the basic components in power transmission system. In recent decades, it applied in aviation, transportation, machinery and instrument etc widely. The tooth shape, meshing and processing technology, are more complicated than ordinary gear. The foreign production processing of spiral bevel gears is "design-processing-detection-adjust" mainly . Domestic production process of integration is impossible. On the situation, The study of spiral bevel and hypoid gears, analysis of machine and machining errors and try to cut to 1 ~ 3 times meeting production needs is necessary.In-depth research on spiral bevel gear meshing theory, basic principle and processing method, according to the principle of meshing gears derive meshing equation. Through the teeth equation, calculating the machine parameters, and a passive wheel - active wheel tilt knife method is studied. Establish a machine- tool coordinate system. Through integro-different equation geometry, local conjugate principle and the coordinate transformation, the cutting edge cutter disk coordinate equation is deduced respectively, the size of the spiral bevel gear wheel gear tooth surface equation and the method of vector equation units. Establish the theory of spiral bevel gear tooth surface equation, comparing with the actual tooth surface analytical error to lay the foundation. And analysis for gear tooth surface measurement techniques. Plan Measurements of the theoretical tooth surface grid, establish measure points and standard reference points. The coordinate grid nodes is obtained and the unit was as a theoretical tooth surfaces with actual data to be used in the actual tooth surface data comparing. Using the method of curved differential theory, the theoretical and practical measurement tooth surfaces which tooth face data analysis for error. In cartesian coordinates by using linear equations under the least-square method beyond isolated from the data each error, to determine the machining parameters and tooth contact pattern correction method. Preliminary discuss the spiral bevel gears processing error estimation of software system development, software development and language environment.Based on the analysis of spiral bevel gears of movement error, explore the feasible measures to solve motion error and presents a new solution. Demand for spiral bevel gear is more and more extensive, diversity, special sex of the actual demand, the optimized design scheme.
