MACHINE DESIGN
BELT DRIVE
There are two types Drives:
- Rigid drives or Non-flexible drives (such as gear)
- Flexible drive (such as Belt, chain and rope)
Advantage of Belt Drive:
- Belt drives can transmit power over considerable distance between the axes of driving and driven shafts.
- The operation of belt drive is smooth and silent.
- They can transmit only a definite load, which if exceeded, will cause the belt to slip over the pulley, thus protecting the parts of the drive against overload.
- They have the ability to absorb the shocks and damp vibration.
Disadvantage of Belt Drive:
- Belt drives have large dimensions and occupy more space.
- The velocity ratio is not constant due to belt slip.
- They impose heavy loads on shafts and bearings.
- There is considerable loss of power resulting in low efficiency.
- Belt drives have comparatively short service life.
