Product Details
BWD3 BLD3 drive reducer single-stage gearbox Speed cycloidal gearbox Reducer
Description :
cycloid gear reducer is a novel transmission mechanism with the principle of Rolling Contact - All major torque transmitting components roll; they do not slide. Rolling motion contributes to minimal friction and high efficiency. Single stage efficiency approaches 93%, and double stage efficiency approaches 86% It is widely used in textile printing and dyeing, light industry food, metallurgical miners, petrochemical, lifting transportation and engineering machinery and other fields.
Feature :
The cycloidal pinwheel reducer produced by our factory is of excellent quality, reliable performance, complete specifications and reasonable price.
1.High speed ratio and high efficiency
2.The single stage transmission can achieve the reduction ratio of 1:87 and the efficiency is above%90. If multistage transmission is adopted, the deceleration ratio will be greater.
3.Compact structure, small volume
Because of the principle of planetary transmission, the input shaft and the output shaft are on the same axis, so the structure is compact and the volume is small.
4.Low running noise and low noise
The mechanism of cycloidal needle tooth engagement is large, the overlap coefficient is large, and the mechanism is stable.
5.Durable and Long Service Life
Because the main parts are bearing steel, after quenching treatment to obtain high strength, and the part of transmission contact with rolling friction, so long durable life,The gear tooth profile of Cycloid Drive enables the sharing of the load by a number of teeth, thus not susceptible to tooth breakage. At least 66% of ring gear rollers and cycloidial disc lobes share the shock load under compression. In addition, major torque transmission Components inside ,Cycloid Drive are made of high carbon chromium bearing grade steel hardened to Rockwell Hardness of HRC 61~63 and with precision grinding. The end result is that Varitron Cycloid Drive are capable of withstanding intermittent shock load up to 500% of its catalog torque rating.
6.Reasonable design, convenient maintenance, easy decomposition and installation, minimum number of parts and simple lubrication, make cycloidal pinwheel reducer trusted by users.
