Problems

Review Questions

1 Why are belt drives are usually arranged at a high-speed stage instead of low speed
stage in a power transmission?

2 What causes a V-belt to have a greater load carrying capacity than a flat belt?

3 Which measure could be used to increase power transmission capacity of a belt
drive?

4 While designing a V-belt drive, how should one solve the following problems?
(1) the speed of the belt is either too fast or too slow;
(2) the contact angle on the driving sheave is too small;
(3) too many number of stress cycles;
(4) too many number of belts.
5 During belt drive design, why do we need to set a limitation on belt speeds?
