Question
The open V-belt drive system shown in Figure 3 has a groove angle of 30° and is
used as a speed booster. The input shaft rotates at 500 rpm and has a sheave with a
pitch diameter of 7.218 in and the output shaft has a sheave with a pitch diameter
of 3.609 in. The center distance between the two shafts is 15.01 in. The coefficient
of friction is 0.25 and the maximum tension in the tight side of the belt is 300 lb.
Determine;
1. The angular velocity of the output shaft.
2. The belt wrap on the input and output sheaves.
3. The belt perimeter length.
4. The length of span between sheaves.
5. The maximum power transmitted by the belt if its mass is 0.04 slug/ft. [Hint:
