Small Size RV Cycloidal Gearbox High Positioning Accuracy

Features and Application of Precision Cycloidal Pinwheel RV Gear Reducer

The precision cycloidal pin wheel RV gear reducer is composed of a cycloidal pin wheel and a planetary support. It is widely used for its small size, strong impact resistance, large torque, high positioning accuracy, small vibration, large reduction ratio and many other advantages. Industrial robots, machine tools, medical testing equipment, satellite receiving systems and other fields.

The working principle of precision cycloidal pinwheel RV gear reducer

The precision cycloidal pin wheel RV gear reducer is composed of a cycloidal pin wheel and a planet carrier. It has the characteristics of large torque, small size, high precision, large transmission ratio and high efficiency.

What is the difference between the precision cycloidal pinwheel RV reducer and the harmonic reducer?

1. The precision cycloidal pinwheel RV gear reducer is mainly used for robot joints over 10 kg, while the harmonic reducer is used for robot joints under 10 kg;

2. Harmonic reducer can significantly reduce the motion accuracy with the increase of use time, while RV reducer will not;

3. Compared with the harmonic reducer, the RV reducer has more complicated components, higher load-bearing strength and greater manufacturing difficulty than the harmonic reducer, so the investment scale of its production line is much larger than that of the harmonic reducer.

It is used for the three joints of the waist and elbow of the leg of the robot with large torque, and the industrial robot with large load uses precision cycloidal pinwheel RV gear reducer for one, two and three axes.

The key to the precision cycloidal pinwheel RV gear reducer lies in the processing technology and assembly technology. It has higher fatigue strength, stiffness and life span, unlike the harmonic drive, as the use time increases, the movement accuracy will be significantly reduced. Its disadvantage is that it is heavy in weight and large in size.

It is used for several axes at the end of industrial robots with small loads or large robots. It is a kind of harmonic transmission device. The harmonic transmission device includes a harmonic accelerator. Harmonic reducer mainly includes: rigid wheel, flexible wheel, bearing and wave generator, all of which are indispensable. Among them, the number of teeth of the rigid wheel is slightly larger than the number of teeth of the flexible wheel. The harmonic reducer used in small robots is characterized by small size, light weight, large carrying capacity, high motion accuracy, and large single-stage transmission ratio.

Both are meshes with small tooth difference. The difference is that one of the key gears in the harmonics is flexible, and it needs repeated high-speed deformation, so it is relatively fragile and has limited bearing capacity and life. RV reducers usually use cycloidal pinwheels. In the past, harmonics used involute tooth profiles. Now some manufacturers use double arc tooth profiles, which are much more advanced than involutes.
