Product Application
R series reducer is a kind of gear is used to reduce the motor speed and improve the output torque of the principle of speed reducer. It uses the gear and gear meshing, with advanced design and novel structure of retarding mechanism.
It has been widely used in metallurgy, mining, petroleum, chemical industry, ship, light industry, food, textile, printing and dyeing.
Product Feature
Our R series helical gear reducers are based on the building block design, so its convenientfor them to fit all types of motors or to connect with other power input, and its possiblefor different types of machines to combine or connect.
1. Compact construction, saves space for mounting, large load-bearing capacity and long life.
2. High transmission efficiency and low noise. A single machine can reach a transmission efficiency as much as 96%.
3. Precise division of transmission ratio with a wide range. The combination of machines can produce a larger transmission ratio at a low output rotational speed.
4. Installation: Foot-mounted, B5/B14 flange-mounted, input shaft, hollow output shaft, etc.
