Flange Mounted Cycloidal Gearbox RV Series For Robotic Welding Positioner

Precision cycloid gear RV series reducer

The precision cycloid gear RV series reducer is a newly emerging transmission. It is developed on the basis of the traditional pendulum planetary transmission. It not only overcomes the shortcomings of the general pendulum transmission, but also because of its small size, light weight, A series of advantages such as large transmission ratio range, long life, stable accuracy, high efficiency, and smooth transmission. Increasingly received extensive attention at home and abroad.

The precision cycloidal gear RV reducer is composed of a cycloidal pin wheel and a planetary carrier. It is widely used in industrial robots due to its small size, strong impact resistance, large torque, high positioning accuracy, low vibration, large reduction ratio and many other advantages. Machine tools, medical testing equipment, satellite receiving systems and other fields. Compared with the harmonic drive commonly used in robots, it has much higher fatigue strength, stiffness and life, and the accuracy of the hysteresis is stable. Unlike the harmonic drive, the motion accuracy will be significantly reduced as the use time increases. Therefore, many countries in the world RV reducers are mostly used in high-precision robot transmissions. Therefore, this kind of RV reducers has a trend of gradually replacing harmonic reducers in advanced robot transmissions.

Difference of Planetary reducers, cycloid gear RV reducers, and harmonic reducers

Planetary reducers, cycloid gear RV reducers, and harmonic reducers are relatively precise transmission equipment in the reducer industry. They have different working principles, different transmission methods, and different application industries.

Planetary reducer and cycloid gear rv reducer are widely used and high-tech reduction transmission equipment. The manufacturing difficulty, technical content, and precision technology of RV reducer are much higher than that of planetary reducer; the application scenarios, industry, and The equipment is also different. The following popular science introduces the difference between planetary reducer and cycloid gear rv reducer.

Planetary reducer gear stages: the number of sets of planetary gears. Because one set of planetary gears cannot meet the larger transmission ratio, sometimes 2 or 3 sets are required to meet the user's requirements for larger transmission ratios. Due to the increase in the number of planetary gears, the length of the 2-stage or 3-stage reducer will be reduced. Increased, efficiency will decrease.

Backlash (transmission accuracy): Fix the output end and rotate the input end clockwise and counterclockwise to make the input end produce rated torque +-2% torque, there is a slight angular displacement at the input end of the reducer, this angular displacement is Backlash. The unit is "minute", which is one sixtieth of a degree. Some people call it backlash.

Planetary reducer has the characteristics of small size, light weight, high carrying capacity, long service life, stable operation, low noise, high precision, wide deceleration range, large output torque, large speed ratio, high efficiency and safe performance. It has the characteristics of power splitting and multi-tooth meshing.

Precision cycloid gear RV series reducer Introduction

The cycloid gear RV reducer is composed of a planetary gear reducer's front stage and a cycloid pin wheel reducer's rear stage. The cycloid gear RV reducer has compact structure, large transmission ratio, and self-locking under certain conditions. The functional transmission machinery is one of the commonly used reducers with low vibration, low noise and low energy consumption.

Technical parameters of precision cycloid gear RV series reducer

Cycloid gear RV reducer has good rigidity, strong impact resistance, smooth transmission, and high precision. It is suitable for medium and heavy load applications. However, RV reducer needs to transmit a large torque, withstand a large overload impact, and has an expected working life. Therefore, a relatively complicated over-positioning structure is used in the design, and the manufacturing process and cost control are difficult. The RV reducer has no elastically deformed force components inside, so it can withstand a certain torque. The bearing of the RV reducer is its weak link, and it is easy to break through the bearing force limit when subjected to force and cause abnormal wear or rupture of the bearing. This problem is more prominent during high-speed operation, so the rated torque of the RV reducer decreases significantly with the input speed.

The use of precision cycloid gear RV series reducer

Cycloid gear RV reducers are mainly used in robot joint transmission, such as industrial manufacturing robots, intelligent mechanical arms, machine tools, medical testing equipment, satellite receiving systems and other fields.
