Difference Between Flat Belt Drive and V-Belt Drive with Comparison Chart
Summary:
The Major Difference Between Flat Belt Drive and V-Belt Drive is that the Flat belt has rectangular cross-section where width is larger than thickness.V-belt has trapezoidal cross-section where larger side width is closely the same with thickness.

| Flat Belt drive | V-Belt drive |
|---|---|
| It is suitable for moderate power transmission when the distance between the shafts is large. |
It is suitable for large power transmission when distance between the shafts is small. |
| There is a chance of slip due to frictional grip between pulley and belt. Hence it is not a positive drive. |
There is less chance of slip due to more frictional a grip between belt and pulley. |
| It requires a large space. | Due to compactness, required less space. |
| For the same value of co-efficient of friction, angle of lap and allowable tension the power transmission by the flat belt is less than that of V – belt drive. |
For the same value of co-efficient of friction, angle of lap and allowable tension the power transmission by V-belt is higher than that of flat belt. |
| High-velocity ratio may not obtain. | High-velocity ratio may be obtained |
Flat Belt Drive
- The flat belt is mostly used in the factories and workshops, where a moderate amount of power is to be
transmitted, from one pulley to another when the two pulleys are not more than 8 meters apart.
V Belt Drive
- The V-belt is mostly used in the factories and workshops, where a moderate amount of power is to be
transmitted, from one pulley to another, when the two pulleys are very near to each other.
