The main structure of the slewing reducer is a structure in which the slewing bearing is used as a transmission follower and a mechanism attachment, and the slewing bearing itself is used to cooperate with the driving power source and the main transmission parts to complete the rotation, deceleration and driving. The slewing bearing is still one of the more critical components, so will the raceway of the slewing drive be damaged? Below, Xiaobian will give you a detailed introduction.
Will the raceway of the slewing drive be damaged?
Will be damaged. As an important component used by many construction machinery, the slewing reducer will inevitably have problems such as wear and fatigue damage during daily use. Because of its slewing structure, it is inevitable that the raceway will be damaged during work. . In addition to the insufficient rigidity of the raw materials in the manufacturing process, the reasons for the damage to the raceway may include unreasonable structural design and insufficient manufacturing accuracy of the reducer. Let’s take a look at it in detail:
Causes of damage to the slewing drive raceway
1. Heat treatment process
The processing quality of the rotary reducer itself is related to the manufacturing accuracy, heat treatment state, and axial clearance. What we usually ignore is the influence of the heat treatment state. In addition to the external force, the most important thing for the damage of the raceway is the depression and cracks on the surface of the raceway during its production. This is related to the hardness of the raceway surface and the hardness of the hardened layer and the core, and these factors are determined in the heat treatment process. For this reason, the depth of the hardened layer on the raceway surface is insufficient and the hardness of the core is low. A more critical factor in its raceway damage.
