4.7.4 MAINTENANCE OF BELTS
The belt drive is an efficient, reliable means for power transmission.
The following are some simple instructions to ensure reliability and long life of the
system.
LOOK AND LISTEN
This allows you to easily identify the defects to be corrected:
- Visual check if any oil or grease is present on the belts, since this may cause
premature deterioration; excess oil on the supports and bearings may cause the
belts to be dirtied, while a lack may cause increased friction and subsequent
burning of the belts due to overload.
- Listening to the noise during transmission.
If there is any screeching when the motor accelerates or during operation at full
load, this means that there is insufficent stretch of the belts.
Once the correct stretch has been restored, if the noise persists try to identify any
overload in transmission (due to wear, seizure, insufficient lubrication...).
The presence of a regular squeaking, similar to that of a bearing that is
insufficiently lubricated, does not cause any damage to the transmission and may
be caused by the presence of dirt.
Do not try to eliminate this noise by oiling the belts.
DIRT AND FOREIGN MATERIALS
Dirt and dust may accelerate wear of the belts and pulleys and obstruct a good
traction.
It is necessary to regularly clean the drive system and prevent any foreign
material from being trapped between the belts and pulleys.
OVERLOADS
Any overload shortens the life of the belts.
Check that operation is taking place under the initial project conditions, and that
no overloads occur due to wear or slipping and superficial burning.
PROTECTIONS
The drive should always be protected by a suitable guard, which not only protects
the operators but also protects the parts from dust or dirt and contact with foreign
objects which may cause serious damage to the system.
BREAKING AND CRACKS
Check the condition of the belts, and see if there are any cuts or cracks, that are
a sign of excessive wear and the need to replace the part.
