5.1 Startup of gear units HW30 and helical-worm gear units HS..
The direction of rotation of the output shaft on the HS40/41 helical-worm gear
units was changed from CW to CCW in comparison to the predecssor SHB4. Swap
two motor feeder cables to change the direction of rotation.
Running-in
period
The Spiroplan
®
gear unit HW30 and the helical-worm gear unit HS.. require a running-
in period of at least 24 hours before reaching their maximm efficiency. A separate
running-in period for each direction of rotation is required if the gear unit is operated in
both directions of rotation. Table 1 shows the average power reduction during the
running-in period.
