The advantages and disadvantages of the precision cycloidal pinwheel RV reducer and the harmonic reducer

The precision cycloidal pinwheel RV reducer has good rigidity, strong impact resistance, stable transmission, and high precision. It is suitable for medium and heavy load applications, but the cycloidal RV gear reducer needs to transmit a large torque and withstand a large overload impact , To ensure the expected working life, so a relatively complex over-positioning structure is used in the design, and the manufacturing process and cost control are difficult. The cycloid RV gear reducer has no elastically deformed force components inside, so it can withstand a certain torque.

The bearing of the precision cycloidal pinwheel RV gear reducer is its weak link. 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 precision cycloid RV gear reducer decreases significantly with the input speed.

Precision cycloid gear reducer is also called cycloid RV reducer, robot RV gear reducer, precision cycloid reducer, manipulator RV cycloid gear reducer, compared with harmonic reducer, precision cycloid RV gear reducer The machine has a longer service life and reliability.

The harmonic reducer has a simple and compact structure and is suitable for miniaturized, low and medium load applications.

Chinese manufacturer of precision cycloidal pinwheel RV reducer

The precision cycloid RV gear reducer developed by Genius Robotics Zhenkang includes a two-stage reduction design, which can provide greater torque, as well as a high reduction ratio and high impact load resistance under the premise of ensuring high precision and light weight.

RV uses the unique pin teeth and RV gear structure of the cycloidal design of rolling contact parts to reduce wear, extend service life, and reduce backlash, making it more resistant to impact than traditional reducers, and further reducing backlash. The reducer is also equipped with a set of large internal angle bearings to achieve greater load capacity in order to reduce the need for external support equipment-thereby reducing design time and installation costs.

The actual symmetrical gear design and all shafts supported by ball bearings guarantee constant performance during the service life and allow the peak value to reach 5 times the rated torque in a short time (for example, during an emergency stop).

Design advantage

The integrated angular bearing increases the rigidity of the reducer and realizes the ability of the reducer to support larger external loads. Therefore, the need for external support equipment is reduced, the number of parts required is reduced, the reliability is increased, and the total cost is reduced.

The continuous meshing design of the cycloidal gear and the pin teeth can achieve a large impact load capacity and a small backlash, because the force is evenly distributed to the entire reducer gear.

The two-stage reduction mechanism reduces vibration because the two cycloid gears are rotating at a lower speed, and the reduced input shaft size reduces the inertia. Various reduction ratios can be obtained by simply changing the combination of stage spur gears.

The use of rolling contact parts in the reducer is beneficial to achieve excellent starting efficiency; reduce wear, obtain longer service life and reduce backlash.

The actual accuracy of the product is higher than the angular transmission error between the input and output shafts described in the sample data.

Measurement method: The input gear is a fixed value, the rated torque is brought into the bidirectional output shaft and the elasticity is measured. Under zero load (static point), before the boundary curve, the area of ​​the distance triangle hysteresis loop is 1 arc minute.

The high-precision cycloid RV gear reducer is one of the core components of industrial robots. It can effectively reduce the speed at the joints of the robot so that it can run at a normal uniform speed. The principle is the one proposed by the German Lorenz Brown in 1926 A kind of planetary transmission mechanism with small tooth difference (also called "RV transmission structure"). Compared with the harmonic drive commonly used in industrial robots, the RV reducer has much higher fatigue strength, stiffness and life, and the accuracy of the return difference is stable. Unlike the harmonic drive, the motion accuracy will be significantly reduced as the use time increases.

Harmonic reducer and precision cycloid RV gear reducer have their own advantages and disadvantages, which need to be selected according to the actual situation. If you are purchasing a reducer, you do not know how to choose a robot that is more suitable for your own , You can consult the technicians of Genius Robotics Zhenkang to assist customers in selecting more accuratel
