gearbox for conveyor, vertical gear box, Forward Reverse Gearbox, electric motor gearbox, high rpm gear speed reducer
1. The wide range of reduction ratio, the nominal speed ratio 10 ~ 200;
2. High mechanical transmission efficiency: secondary was ninety-six percent, and the tertiary by ninety-four percent;
3. Smooth operation, low noise;
4. As a result of the 42 crmo, 35 crmo modulation by forging processing, production of gear shaft and gear, respectively, so the service life is long, high carrying capacity;
5. Easy to overhaul, easy to install.
1. Gear circumferential velocity is not more than 16 m/s;
2. High speed spindle speed is not more than 1000 revolutions per second;
3. The working environment temperature for - 40 ~ 45 degrees;
4. Can be a positive direction.
