Abstract
This Paper requires that" with quality beg development, with benefits seek to live on to store ", under the prerequisite of guaranteeing the quality of element processing , have raised productivity and reduced production cost, is one of mainly direction of domestic and international modern machining technology developing. Through knowing and analysis the configuration of the casing part drawing for WH212 gear reducer, so as to analysis the process, make process explanation and analysis the technical requirement and the precision of gear reducer. Then, carry out the design of clamping apparatus and analysis the precision and error for the processing of bearing hole and the base hole of the casing of gear reducer, this technology and the design result of clamping apparatus can apply in production requirement.
