Cycloidal Gearbox Introduction

Precision cycloid gear RV reducer, also known as robot reducer

The global industrial robot market is mainly articulated industrial robots. The robot is composed of a controller, a servo motor and a reducer. The cost of the three core components of the reducer, servo and controller respectively account for 30%-50%, 20%-30%, and 10%-20% of the robot cost. The reducers used in industrial robots mainly include precision cycloid gear RV reducers and harmonic reducers. How to distinguish between use?

The precision cycloid gear RV reducer is generally used in the first, second and third joints of heavy-duty robots. Compared with the harmonic reducer, the key to the precision cycloid gear RV reducer lies in the processing technology and assembly process.

Features of precision cycloid gear RV reducer

The precision cycloid gear RV reducer has higher fatigue strength, stiffness and life. Unlike the harmonic drive, as the use time increases, the motion accuracy will be significantly reduced. Its disadvantage is that it is heavy in weight and large in size.

The precision cycloid gear RV reducers currently used in the market are mainly Nabtesco from Japan, Tsutien from Taiwan, and Genius Robotics Zhenkang from Chinese brands.

The difference between precision cycloid gear RV reducer and harmonic reducer

Harmonic reducer is characterized by small size, light weight, large carrying capacity, high motion accuracy, and large single-stage transmission ratio. Japan's HarmonicDrive company almost monopolizes the entire field of industrial robot harmonic reducers, and the current global market share is as high as 80%. In the industrial development of domestic harmonic reducer, Yilu has the fastest development. It has been supplied for trial with some domestic robots and even foreign robot manufacturers. It is expected to exceed 30,000 units this year and has a market share of more than 60 in the domestic harmonic reducer. %.

The precision cycloid gear RV reducer is mainly used for heavy-duty robots, concentrated in the first few joints, and the harmonic reducer is mainly used for the end axes of light and small industrial robots.

Japan's Nabtesco precision cycloid gear RV reducer almost monopolizes the precision cycloid gear reducer RV market. The precision cycloid gear RV reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the required number of revolutions and obtain a larger torque.

According to the precision, the precision reducer can be divided into standard precision and high precision; according to the purpose, it can be divided into military and civilian; according to the operating environment, it can be divided into standard environment, low temperature environment, clean room environment and vacuum environment.

The most important basic components of industrial robots, each joint must use different precision reducer products
