Pre-stage planetary gearbox ( General machine building )
A project has been completed to replace a three-stage gearbox with a single-stage planetary gearbox with a preliminary stage (patents RU2677952 and RU2683896).
Gearbox Parameters:
- input power - 66 kW
- input revolutions - 600 rpm
The project was carried out as part of the import substitution program for gearboxes for rolling mills.
Benefits:
1. Less Parts and Bearings - More Reliability
2. 40% less weight
3. Smaller dimensions
4. Reduced manufacturing cost 5. Efficiency - 95%, against 90% of the prototype
6. Estimated durability - 50000 hours
The principle of transmission of rotation between parallel shafts used in a single-stage gearbox:
Weight: 2731 kg. Rated torque: 175000 Hm. Gear ratio number: 175
