QJR-D QJRS-D QJS-D metallurgical hard tooth surface reducer

Medium hard tooth surface reducer is widely used in the transmission mechanism of various mechanical equipment such as transportation, metallurgy, mining, chemical industry, light industry and so on.
1. Wide range of reduction ratio, nominal speed ratio 10-200;
2. High mechanical transmission efficiency, up to 96% in the second stage and 94% in the third stage;
3. Smooth operation and low noise;
4. Due to the use of 42CrMo and 35CrMo through forging and tempering treatment, the gear shaft and gear are respectively made, so the service life is long and the bearing capacity is high;
5. Easy to install.
