R series helical gear reducers with cast-iron housing are mechanical power transmission components that drive a load at a reduced fixed ratio of motor speed. Output torque is increased;the power is constant (less efficiency losses). Output shaft is inline, parallel to input. Helical gears offer smoother, quieter operation than most other gear types. Features R series helical gear reducer is made by the combination of international technology, it has very high technological content. 1. Space-save, high reliability, high overload capacity, the power can reach to 200KW. 2. High superior performance, low energy consumption, high efficiency of more than 95%. 3. Small vibration, high energy saving, low noise. 4. Modular design, multiply motor combinations, fine ratio classification, suitable for various working conditions. 5. The design of outline is suitable for full range installations. Application R series reducers are widely used in industrial production equipment and transmission equipment.
