Stöber PS two-speed gearbox
Date: 2 June 2014
The 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.
