Fig. 3-4 Gearbox design for 1PH7, SH 100 to 160
For selector gearboxes, the following applies:
Both gearbox ratios are electrically selected and the setting is monitored using limit
switches.
The gearbox output shaft lies coaxially to the motor shaft.
Torsional play (measured at the gearbox output shaft):
Standard:
For milling and machining with interrupted cut, the following special versions are
available on request for shaft heights 100 to 160:
S Lower play: max. 20'
S Lower play for increased requirements: max. 15'
Belt pulley
S The belt pulley should be in the form of a cup wheel.
S The gearbox output shaft has a flange with outer centering and tapped holes to
retain the belt pulley.
S The complete drive should be designed to be as stiff as possible using large
belt cross-sections. This has a positive impact on the smooth running properties
of the drive.
