V-Belts are most common type of drive belt used for power transmission. They provide the best combination of traction, speed transfer, load distribution, and extended service life.
You should know the basic and important facts about V belt because using wrong V belt could cause machinery damage or can create safety issues. The use of belts depends on the applications. There are some environment and application design criteria that influence V belt selection:
- Minimal take-up
- Oil resistance
- Ozone resistance
- Clutching
- Energy efficiency
- Power capacity
- Ambient temperature
- Shock Loading
- operation
Some of the common applications of V-Belts are:
- Washing Machine
- Car Engines
- Combines
- Threshing Machines
- Electric Vacuumed Machine
- Mechanical Clutch
- Treadmill
- Truck
- Tractor
- Swat Trucks
- Some turntables (record players)
- linear actuators
- Mechanical Clutch
Most common problems faced by v-belt users and its solutions
Misalignment
Misalignment can occur due to drag, low installation tension, belt wear, degradation of the tensioner spring, a belt that’s too long, seized bearings or contaminants of the same type that cause chirping. Additionally, if the belt is wet from getting splashed, it could lose traction.
Solution: Regular check of the condition of V-belt can alert the user from misalignment of V-Belt.
Insufficient Rigidity
Insufficient rigidity of V-belt can cause belt to slip, screeching sound.
Solution: Re-tensioning of V-belt can help to correct the problem. Regular check of the positioning of the sheaves, and the belt need to be realigned to correct the rigidity issue.
3.Breakage of the shaft
Most common problem faced by V-belt users are breakage of the shaft, it is causes often because of over-tensioning.
Solution: Practical space limitation can stop help to prevent breakage of shaft.
4. Spin burn
It can be caused by damaged pulleys, incorrect tensioning or using wrong belt cross section type, excessive oil, grease or moisture.
Solution: You need to find out the unnecessary wear or re-tension the v-belt.
5. Underside cracked
Cracks on v-belt appear due to excessive or unnecessary heat. Misaligned V-belt can also cause the crack on v-belts.
Solution:You need to check the unnecessary heat being exposed to v-belt.
