The on-site storage management of HM heavy truck gear should pay attention to the possibility of avoiding mixing when the oil is used, especially the mixing of HM heavy truck gear oil and oil. Gear oil mixed with oil will lead to abnormal engine wear in a short time; The oil mixed with the gear oil causes the viscosity of the gear oil to decrease and the characteristics to change, resulting in short abnormal wear of the HM heavy truck gear. High humidity in the environment, serious damage caused by many reasons, scratches, fragmentation, etc., will also cause the failure of HM heavy truck gear.
The failure of HM heavy truck gear generally occurs in the tooth surface, and rarely occurs in other parts. According to the causes of gear failure in the work, the common failure forms of gear can be analyzed, such as tooth break, tooth surface bonding, tooth surface fatigue pitting, tooth surface wear, plastic deformation and so on.
