The HBT CST30 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).
Maximum Output Torque
300 000 Nm (221,269 lb/ft)
Max. Input Speed
1,800 rpm
Rated Power P
up to 500 kW (800 hp)
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.
Reduction ratio of 24, 4:1, 33:1, 39:1 and 50:1 is available. Depending on the ratio, the permissible input power of the gearbox can be up to 500 kW/680 hp at a mains frequency of 50 Hz (≈ 1,485 rpm) or 600 kW/816 hp at a mains frequency of 60 Hz (≈ 1,782 rpm). The permissible output torque is 300,000 Nm (max for 3 seconds). The rated continuous output torque is 130,000 (i=50).
