Pulley and belt transmission system (3:1)

Pulley and belt transmission system (3:1)

Krick 42131

The belt transmission is used, for example, in the Titanic of Mantua to achieve the friction connection between the electric motor and the stern shaft.

Belt drive has several advantages:
- The gearbox reduces the speed of the propeller and improves efficiency. 3:1 discount rate.
- The shaft system can be placed deeper and more compactly in the hull than with a direct drive.
- The operating noise is lower than with gear reductions.
- In case of locking of the propeller, the rubber ring acts as a slip clutch.
