Number of stages: the number of sets of planetary gears. Since a set of star gears cannot satisfy a large gear ratio, sometimes 2 or 3 sets are required to meet the requirements of a larger gear ratio. Due to the increase in the number of star gears, level 2 Or the length of the 3-stage reducer will increase, and the efficiency will decrease.
Return gap: The output end is fixed, the input end rotates clockwise and counterclockwise, so that the input end produces a rated torque +-2% torque, the input end of the reducer has a slight angular displacement, this angular displacement is the return clearance. It is a "minute", which is one-sixtieth of a degree. Some people call it backlash/return. Servo motor reducer is a versatile industrial product that can compete with other military grade reducer products. However, it has the price of industrial grade products and is used in a wide range of industrial applications.
The servo motor reducer is small in size, light in weight, high in load carrying capacity, long in service life, stable in operation and low in noise. It has the characteristics of power splitting and multi-tooth meshing. The maximum input power is up to 104kW. Suitable for lifting, transportation, engineering machinery, metallurgy, mining, petrochemical, construction machinery, light industrial textiles, medical equipment, instrumentation, automotive, marine, weapons and aerospace industries, a new series of planetary series WGN fixed shaft transmission reducer , WN sub-mother gear reducer, elastic load-carrying gear reducer. The servo motor reducer is a new type of reducer with wide versatility. The internal gear adopts 20CvMnT carburizing and grinding. The whole machine has the characteristics of small structure size, large output torque, high speed ratio, high efficiency and safe and reliable performance. This machine is mainly used for the slewing mechanism of tower cranes, and can also be used as supporting components for lifting, digging, transportation, construction and other industries.
