Slewing drive S-II-O-1091

precision grinding gear slewing drives are applied to the robot bases of automatic production lines, this working condition has relatively high requirements for the slewing drives. First of all, slewing drives need to have large tilting moments. The working conditions of the manipulator bases are continuously eccentric and the tilting moments are constantly changing. When choosing a slewing drive, choose a relatively large safety factor. Secondly, the instantaneous speed of the slewing drive is relatively high. The bases of the manipulators need to drive the manipulators to rotate rapidly to place the workpieces in the designated positions. The faster the work rhythm, the higher the instantaneous speed required for the slewing drives. Finally, slewing drives frequently start and stop and frequently accelerate and decelerate, under such working conditions, it’s necessary to select slewing drives with large output torques and also choose slewing drives with large modules. In this way, under the working conditions of frequent starting and stopping, acceleration and deceleration, the teeth of the slewing drives are not easy to be overloaded, and not easy to appear fatigue wears or peeling. The slewing drives can maintain high-precision operations for a long time. In the process of design and selection, many working conditions can be classified into this working condition, such as servo positioners, light excavation equipment, etc. In the process of model selection, it is necessary to fully consider various factors and select the optimal slewing drive scheme.
