In order to reduce the development cycle of the bearing housing and improve the design efficiency,the three-dimensional parametrie design of the high-speed and heavy-load bearing housing is carried out by means of modern digital design.Taking UG10.0 as the three-dimensional parametric design platform.The physical thermal analysis method is used to establish the mathematieal relationship between the deepness of cooling groove and the hearing dimension,bearing speed and load.The mathematical relationship is used to establish three-dimensional parametric model that have the relationship between the deepness of cooling groove and the bearing dimension,bearing speed and load.The finite element analysis and verification are carried out by using NX FLOW.The results show that the parametric model obtained by changing the geometric size or load parameters satisfies the actual working requirements,and the intelligent three-dimensional parametric design of the high-speed and heavy-load bearing is realized.It provides the same new product development with a smart and efficient design method.
