5.4 Gear
Gearbox mounted outside the spindle box
The following advantages are obtained by locating the gearbox outside the spindle box:
● Gearbox vibration is not transferred.
● Separate lubricating systems for the main spindle (grease) and selector gearbox (oil).
● No noise and no temperature fluctuations caused by the gearbox pinion wheels in the
● Instead of using belts, the drive power can also be transferred from the gearbox output
Vibration magnitudes
Motor + gearbox: Tolerance grade R (acc. to DIN ISO 2373)
This also applies if motor tolerance level S is ordered.
Seal between motor flange and gearbox flange
On SH 132 and SH 160, the seal between the motor flange and gearbox flange must be
made with sealing compound (e.g. Terostat 93, Teroson) due to the uninterrupted centering
