Upgraded gearbox with EC gearing ( General machine building )

Gearbox with EC-gear modernized.

1. The minimum number of steps is 2 (for prototypes 3), which increases the efficiency of the gearbox by (1-2%)
2. EC-gearing increases the transmitted moment by 30% compared with involute gearing. Or increases the durability of gear pairs.
3. The minimum dimensions + minimum mass for the EC gearbox with the initial data of U-20.83 and 55 kW (1500 rpm) are obtained
4. The use of an electric motor with a hollow rotor made it possible to reduce the linear dimensions of the drive (by approximately 150 mm).
5. Based on the design of the EC-gearbox, a line-up similar to gearboxes can be created (different gear ratios, different powers)
6. The minimum cost in serial production (due to the reduced mass and small number of gears and bearings)
