4.7.1 REDUCTION GEAR
The reduction gear does not require special maintenance precautions; you only
need to check the level of lubricating oil through the inspection hole in the casing.
It is good maintenance practice to protect the seal rings with waterproofing
lubricating grease, and to protect the locking system on the shaft from the effects
of oxidation which would make it difficult to disassemble the reduction gear, if
necessary.
For reduction gears equipped with cooling coil inside the casing for artificial
refrigeration, the water circuit needs to be drained off completely if room
temperature drops below +4 °C.
As the reduction unit is pivoting its movement is free and will increase when the
machine runs loaded. This movement can be considered normal when all the
belt-tensioning elements and reduction gear support elements have been
properly tightened, using also lock nuts.
WARNING: It is forbidden to alter the tensioning system of the reduction
gear, particularly if this will make the system rigid. Inadequate constraints
can cause improper stress on the drive system resulting in breakage of its
elements.
For further information and instructions for disassembling the reduction gear from
the machine refer to the reduction gear manual, included in Section 6 –
INFORMATION ABOUT SUPPLIERS.
