Ip this paper Straig^j; tooj,h cylindrical gears ip the transmission system of two types of engine,WP-7 and WP-13 fabricated by Li Yang conformity between process machinind machining gear and design intention of the gear is major clue. Analysis is made from following eight By studying these difficult problems occurred in our factory, according to the material about gear calculation. Some effective calculation methods to solve these problems are obtained and these calculation methods are commonly used. It is proved that these methods are feasible. |
