Introduction to the planetary reducer

When there is few tooth number difference between internal gear and external gear, the involute internal meshed cylindrical gear pair make upplanetary reducer with few tooth difference according to the type NN, NGW or N(as the figure below). Theepicyclic gear train of planetary reducer is mainly composed of planet wheel, planet carrier, center wheel and bearing, it has series advantages like large range of transmission ratio, high transmission efficiency, strong carrying capacity, compact structure, small volume, light quality, easy manufacturing, etc..The planetary reducer can be widely used in aviation, aerospace, industrial robot, national defense weaponry, medical equipment, instrument, textile machinery, printing and packaging machinery, food processing machinery, and other fields.

Product feature:

The planetary reducer has thesame great advantages with harmonic reducer such as compact volume and big reduction ratio; At the same time it is different from harmonic reducer that the flexible gear of harmonic reducer exists fatigue failure caused by frequent circulatory alternating stress, Furthermoreit can achieve performance such as large output torque and high stiffness.

Guide for selection

According to the load situation, condition coefficient to determine the output torque, reduction ratio and the model size, please contact Chongqing BTG technology company, the company can be customized production according to user requirements..．Besides, aim at the planetary reducer running under the environment of vacuum (better than 1.0×10^-3Pa), high-low temperature (-60℃~110℃), the company can providepecial lubrication solutions.
