一、引言轴承座是机械设备中常用的部件。轴承座的设计通常是根据轴颈尺寸和轴承类别型号查阅机械设计手册,选择已标准化的轴承座;或参照标准化的轴承座确定结构尺寸。但是在重载或冲击载荷作用下的轴承座底板常出现断裂情况,而按上述方法选用的轴承座,无法确切知道其强度是否满足 I. Introduction Housings are commonly used in mechanical equipment components. Design of housings is usually based on journal size and bearing type reference mechanical design manuals, select the standardized bearing housings; or with reference to the standard bearing housings to determine the size of the structure. However, under heavy load or impact load under the bearing plate often appear broken, and use the above method of selection of the bearing, can not know exactly whether its strength
