3. Cracking failure bearing cracking failure is the primary cause of shortcomings and overload. When the applied load exceeds the data strength limit, the cracking of the part is called overload cracking. The overload is caused by the host's sudden fault or the device is not properly. The micro-crack of the bearing parts, Shrinkage, air bubbles, large foreign objects, overheating arrangement and partial burns will also cause cracking in the shortcomings during impact overload or severe oscillation; it is called fault cracking. It should be pointed out; the bearing is in the process of production; In the process of re-inspection, casting and heat treatment quality control, processing and processing, the above-mentioned shortcomings can be correctly analyzed through the instrument; the control must be strengthened in the future. However, in general, the bearing cracking failures that are generally presented are mostly overload failures. . /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
4. The clearance changes the failed bearing in the work; because of the influence of the external or connotation elements; the original cooperation gap is changed; the precision is reduced; even the formation of "biting death" is called the clearance modification failure. The external factors such as the interference amount is large; the device is not In place; large amount of expansion caused by temperature rise, instantaneous overload, etc.; connotation elements such as residual austenite and residual stress are unstable, which are the primary reasons for the failure of the play change.
