Stober PS

The Stöber PS two-speed gearbox is specially developed for main spindle drives of machine tools. Gear ratio 1 is designed as a loss-optimized direct gear (1:1) for high speeds. If a high motor torque is needed for machining hard materials or extreme heavy-duty machining, the operator can simply switch to gear ratio 2. The integrated set of planetary gear units is available in designs i = 4 or 5.5.

At high speed, the unit operates in the direct-drive mode. At the time that a high force is required, it is switched to the deceleration mode. Transmissions are possible up to a torque of 2200 Nm.
The PS gearboxes are available with a solid shaft for direct coupling with a spindle. The other embodiment has a flanged shaft for direct assembly of a timing belt pulley.
On the input side the PS gearboxes are fitted with an adapter and backlash-free coupling for direct mounting to a servomotor.
