ONE 7TS – Maintenance
GENERAL
Belt drive is an efficient and reliable way of transmitting power.
Described below are some simple precautions designed to ensure reliability and durability for the system.
Visually check for oil or grease on the belts, as this could cause early deterioration; excessive oil on supports
and bearings can cause soiling of the belts, while insufficient oil can cause friction and therefore burning of
the belts due to overload.
Listen to the sound made by the drive elements.
If you hear a squealing noise during motor acceleration or with full load operation, it means that belt tension
is insufficient.
Once you have restored correct tension, if the noise persists try to identify a possible cause of drive overload
(due to wearing out, seizure, insufficient lubrication....).
The presenza of a constant squeaking, similar to the noise made by a poorly lubricated bearing, does not
result in particular damage to the drive and can be cause by the presence of dirt.
Do not attempt to solve this noise by greasing the belts.
Dirt and dust can accelerate wearing out of belts and pulleys and prevent efficient drive.
It is therefore necessary to regularly clean the drive system and avoid material becoming trapped between
belts and pulleys.
Overloads shorten belts life.
Ensure that operation is occurring in the initial design conditions, that no overload is caused by wearing out,
or slipping and surface burning.
The drive must always be protected with a cover, not only to prevent damage to people but also to keep out
dust or dirt and prevent contact with foreign object that could seriously damage the system.
Check belt wear, look for cuts and cracks that indicate bad wearing out and need for replacement.
Check and maintain correct belt tension preventing abnormal vibrations.
Make sure that the belts are not exposed to heat sources; exposure to temperatures above 60°C will affect
their lifetime.
Check condition of belt sides; abnormal wear may indicate slipping or excessive wearing out of pulley
grooves.
Instructions for belt tightening
Ensure that the v-belt is correctly tightened; improve tension if needed.
ATTENTION
:
belt drive can cause crushing and catching hazards. Fixed guards should be used
at all times and removed only after the machine has completely stopped.
The ideal tension is the lowest at which belts will not slip under the maximum load.
During the first 24/48 hours of run-in you need to check tension frequently; bear in mind that excessive ten-
sion reduces the lifetime of belts and support bearings.
The belts should be tightened immediately if slipping occurs.
Belt slipping can cause overheating and create hazard situations especially if the machine is designed for
operation in dangerous zones.
