High Transmission Cycloidal Gear Reducer With Hollow Shaft

Types of high-precision reducers

There are three main types of existing high-precision reducers, namely precision RV reducer, cycloid reducer and harmonic reducer. Among them, the cycloid RV reducer has more advantages than other reducers in terms of transmission accuracy, rotation efficiency, torque stiffness, and service life. It is the most widely used in the field of high-precision transmission and has a higher cost performance.

Although the three types of reducers are different in principle and structure, they can all be used in industrial robots, CNC machine tools and precision instruments that require precision transmission and are widely used.

When the precision cycloidal pinwheel RV reducer leaves the factory, the technical index of the return error must be controlled within 1.5 arc minutes, and the technical index of the transmission error must be controlled within 1 arc minute.

As the user unit of the precision cycloid pinwheel RV reducer, the industrial robot manufacturer must strictly test the key index parameters of the RV reducer before processing and assembling. The general robots ABB FANUC, YASKAWA, KUKA, before purchasing products, Both require a three-year reliability test experiment. When Genius Rbotics Zhenkang developed the RV reducer, the test experiment time was 6000 to 8000 hours. "Genius Rbotics Zhenkang is China's largest and most professional manufacturer of RV reducers, occupying 30% of the Chinese market and becoming Nabtesco's biggest competitor.

For the production of precision cycloid RV reducer, various parameters of the finished RV reducer also need to be tested

Existing precision cycloid needle RV reducer test schemes (test schemes for transmission error, rotation efficiency, return error and torsional stiffness) mainly have three situations, namely:

(1) Use traditional instruments to conduct test experiments, and manually record and process data. The disadvantages of this scheme are large workload, low efficiency and poor accuracy.

(2) A variety of professional instrument combinations, using computer data acquisition and synthesis processing. This method needs to program the interface program between the computer and the traditional instrument, so the versatility is poor.

(3) Adopt the method of testing parts and then calculating with theoretical model. However, the calculated result is usually far from the actual value and can only be used as a reference during product design.

The precision cycloid needle RV reducer test should be carried out on a dedicated test bench. During the test of the cycloid RV reducer, the indoor ambient temperature should be in the range of 5°C to 40°C. The air around the cycloid RV reducer should circulate freely, and forced circulation is not allowed. The test environment must ensure that there is no vibration that affects the test.
