The helical gear design involves lots of complex calculation formula, and design process to keep consulting a large number of maps and data tables. While the traditional gear design is often time-consuming manual calculation, and low efficiency, the design procedure prone to errors, the design cycle is long, and often because calculation errors caused larger costs loss. This gear parametric design module interface using form operation, the designers ways simply choose or input the original gear design parameters can complete gear transmission parameter design and strength check and realize the automatic drawing working drawing parts. Compared with the traditional design method, USES computer aided design is simple, effective, convenient, greatly enhancing the gear transmission design efficiency, and shortened the design cycle, which makes the design result is more accurate and reliable.
