In the processing of the existing is still relatively low level. The slow development of manufacturing technology, processing equipment is backward, processing the low level of automation, improve bearing life and reliability technology research has failed to make a breakthrough. Investigation of the subject in bearing bush positioning lip milling in home and abroad under the premise of understanding, analysis of the characteristics and the development tend of the technology, in this article. we present the overall design of the bearing efficiency. We are also based on finite element theory, the use of ANSYS, the dynamic analysis of the main shaft of bearing bush positioning lip milling was analyzed to verify the structural design is reasonalble and reliable. Bearing bush positioning lip milling in this article isone of the few types of bearing bush positioning lip milling both domestic and overseas at present, it belongs to there are no special lathes which are used to produce bearing bush in China. Moreover, it is expensive to import the same type lathes and the maintenance charge is very high. It is vitally necessary to design and produce special purpose machines by ourselves. Keywords positioning bearing bush lip, milling, structural design 。充值下载即送 CAD 图纸, QQ 36396305 目录摘要....................................................................................................................
