Niro Soavi S.p.A
4.7. TRANSMISSION
The machine is equipped with a drive system consisting in:
− pivot-mounted parallel-axle reduction gear, fitted on the machine’s crankshaft;
− pulley and V-belt drive between main motor and reduction gear.
CAUTION: All inspection and maintenance operations must be
carried out with the MACHINE NOT IN OPERATION; the power
mains switch must be LOCKED IN THE ON POSITION (with a
padlock) for the safety of personnel.
The elements of the drive system usually require only a visual inspection, carried
out with the machine not in operation, to check for possibile lubrication oil leaks
and, more importantly, for loosening of nuts, bolts, belt tensioning components
and reduction gear support parts.
Excessive movement of drive components, due to loosening of locking elements
caused by vibrations, can result in slack couplings and consequent breakage of
elements during machine operation.
CAUTION: It is important to regularly check tightening of nuts and bolts in
the belt tensioning system and reduction gear support system. Abnormal
vibrations due to incorrect machine operation or cavitation conditions can
cause these components to loosen and damage the drive system.
Instructions for maintenance of drive components are given below.
