2-speed gearboxes for SIMOTICS M-1PH8 asynchronous motors
The performance features of the two-speed gearbox for SIMOTICS M-1PH8 asynchronous motors are as follows:
Drive power up to 100 kW (134 HP)
Constant power range at drive shaft up to 1:24
Suitable for both directions of rotation
Motor shaft heights SH 100 to SH 225
Types of construction IM B35 and IM V15 (IM V35 available on request)
The advantages listed below are gained by mounting the gearbox outside the spindle box:
Easy adaptation to the machine tool
Low noise and no temperature fluctuations due to gearing inside the headstock
Separate lubrication systems for the main spindle (grease) and the change-speed gearbox (oil)
Gear efficiency > 95 %
The drive power can also be transferred from the gearbox output via a gear wheel (on request) or coaxially via a flexible coupling rather than by a V-belt.
