Description of RPR Series Slewing Drives

Slewing drive is a crucial component in keeping the weight and size of tower cranes, wind turbines, high-altitude platforms, unloading arms, excavation, and construction equipment to a minimum.Their planetary structure can withstand high torque values while maintaining small size, weight, and efficiency. There is a wide range of transmission ratios available, and you can choose the size and type of motor most suitable for user requirements: hydraulic, electric, and pneumatic. Simple installation, operational reliability, and versatility make these devices suitable for the worst work and environment.

Critical Points of Model Selection

 The high torque planetary gearbox is the most critical type of high torque planetary gearbox matching the servo motor. When selecting high torque planetary gearbox, first, determine the reduction ratio of the high torque planetary gearbox. If the standard high torque planetary gearbox does not have the transmission ratio you need, please choose a compact or customized high torque planetary gearbox.After determining the reduction ratio, multiply the rated torque of the servo motor you choose by the reduction ratio to obtain a value that is in principle, less than the rated output torque of the same kind of high torque planetary gearbox provided in the product record, and consider the overload capacity of the drive motor and the maximum operating torque required. The maximum operating torque required shall be injected into the 2-bit rated output torque. After meeting the above conditions, please choose the most miniature high torque planetary gearbox. The cost of the small high torque planetary gearbox is relatively low.Then consider the return clearance of the high torque planetary gearbox. The smaller the return clearance, the higher the accuracy and the higher the cost. Users must choose a series of planetary gearboxes that meet their accuracy requirements. Lateral/radial forces and average life should also be considered. The lateral/radial force ample torque planetary gearbox has high reliability and is not easy to make mistakes in installation and use. Generally speaking, the average service life of a servo motor is much longer than that of a servo motor.
