CST Drive System

CST45 V

The HBT CST45 V gearbox is suitable for use as conveyor gearbox installed on drive frames and fitted to their input shafts. There are two designs available for most CST drive systems: an in-line gearbox design (the P gearboxes) and an angular gearbox design (the KP gearboxes).

A CST gearbox comes in three parts: a supply unit, a first planetary gear stage and an output unit comprising a second planetary gear stage. The KP gearbox also comes in three parts. The supply unit and output unit are the same as the ones from the P gearbox, but the first planetary gear stage is replaced by a bevel helical gearbox unit. The KP gearbox design is available in a left-handed and in a right-handed version. It is also possible to mount the electro-hydraulic controller either inside or outside the supply unit.

The roller bearings of the bevel gear shaft are lubricated by forced lubrication via the built-in oil pump (usually responsible for cooling oil supply to the CST clutch). All other gearings and roller bearings are lubricated by means of splash lubrication.

A reduction ratio 33:1 is available. In comparison with the standard CST45 design, the CST45 V gearboxes can endure higher input power.

The permissible input power of the gearbox for the specific ratio of 33:1 is 1050 kW/1,428 hp at a mains frequency of 50 Hz ( ≈ 1,485 rpm) or 1260 kW/1,713 hp at a mains frequency of 60 Hz ( ≈ 1,782 rpm). The permissible output torque is 450,000 Nm (max for 3 seconds). The rated continuous output torque is 220,000 (standard CST45 175,000 Nm).
