Belts along with motors, shafts, and pulleys are the key components of power transmission in belt drive systems. While belts require little maintenance, improper belt tension, misaligned pulleys, mishandled belts, and environmental factors are common problems that can shorten the life of the belt and cause the system to stop operating.
Improper V-belt tension
If the belt is not properly tensioned, it will be too loose or too tight on the pulleys. A belt that is too loose on the pulleys can cause slippage, which causes friction to generate heat. This heat can damage your rubber straps and cause them to crack and break. A belt that is too tight can increase the stress on the bearings and overload the motor, which can lead to motor failure. Ensuring your belts are properly tensioned is simple and can help prevent additional costs associated with motor or belt failures.
Here are some signs of an improperly tensioned belt:
belt cracking
broken pieces
hardened appearance
Belt squeals when starting
Premature wear of pulleys
The Motor current is too high
Front motor bearing wear
Pulley misalignment and its effect on V-belts
Pulleys need to be properly aligned to prevent premature belt and pulley wear, increased vibration, and drive instability. The following are the types of dislocations:
Parallel: One pulley is out of the plane of the other, but their axes are parallel
Angular: The pulleys are in the same plane of the drive system, but their axes are not parallel.
Combinations: Pulleys may exhibit a combination of parallel and angular misalignment.
Always check the alignment of the pulleys after tensioning the belt, as sometimes the pulleys may move during tensioning. To check the alignment of the pulleys, you can use a laser alignment tool or a machine ruler.
