齿爪式粉碎机由于结构紧凑、操作简单、维修方便,深受用户欢迎,已成为我国农村量大面广的农副产品加工机具之一。但在使用过程中,粉碎机的主轴前轴承过早失效破坏的情况时有发生。严重时会打坏机器,不仅影响生产,而且危及人身安全。一、齿爪式粉碎机主轴前轴承正常失效的原因齿爪式粉碎机主轴前轴承大多采用滚动轴承。滚动轴承失效的形式主要有: 1.轴承在交变应力的作用下产生疲劳,成片状剥落而失效; 2.轴承在大的静载荷或冲击载荷作用下,滚动体 Due to its compact structure, easy operation and convenient maintenance, the claw grinder has been well received by users and has become one of the agricultural and sideline products processing tools in China. However, in the course of use, the main shaft front grinder smash the failure of the spindle occurred from time to time have occurred. In severe cases, the machine will be broken, not only affecting the production, but also endangering personal safety. First, the claw grinder main reason for the normal failure of the front axle bearings Tooth claw grinder spindle bearings are mostly used for rolling bearings. Rolling bearing failure in the form of: 1. Bearings in the role of alternating stress fatigue, flaking and failure; 2. Bearings in a large static load or impact load, the rolling body
