Oil expansion tank
SEW‑EURODRIVE recommends using an oil expansion tank for gear units and gearmotors in mounting position M4 in the following cases:
- For input speeds > 2000 min-1
- For sizes 77 – 97 and input speeds > 1800 min-1
- For gear units and gearmotors in size 107 and larger
The following figure shows the oil expansion tank mounted to a gear unit.
The oil expansion tank is delivered as an assembly kit for mounting onto the gearmotor. In case of limited space or of gear units without motor, the oil expansion tank can also be mounted to nearby machine parts.
Transverse acceleration is not permitted for gear units with expansion tanks with fixed piping for third-party motors and for servomotors.
If you require further information, contact SEW-EURODRIVE.
