Ratio of Driving Tensions for Flat Belt Drive
Consider a driven pulley rotating in the clockwise direction as shown in Fig.
Power transmitted by a Belt
Fig. shows the driving pulley (or driver) A and the driven pulley (or follower) B. We have already discussed that the driving pulley pulls the belt from one side and delivers the same…
Length of a Cross Belt Drive
We have already discussed that in a cross belt drive, both the pulleys rotate in opposite directions as shown in Fig. Let r1 and r2 = Radii of the larger and smaller pulleys, x =…
Length of an open Belt Drive
We have already discussed that in an open belt drive, both the pulleys rotate in the same direction as shown in Fig. Let r1and r2= Radii of the larger and smaller pulleys, x =…
Slip of Belt
In the previous articles, we have discussed the motion of belts and shafts assuming a firm frictional grip between the belts and the shafts. But sometimes, the frictional grip becomes…
Velocity Ratio of a Compound Belt Drive
Sometimes the power is transmitted from one shaft to another, through a number of pulleys, as shown in fig. Consider a pulley 1 driving the pulley 2. Since the pulleys…
Types of Flat Belt Drives
The power from one pulley to another may be transmitted by any of the following types of belt drives: 1. Open belt drive. The open belt drive, as shown in Fig. 11.3,…
Types of Belts
Though there are many types of belts used these days, yet the following are important from the subject point of view: 1. Flat belt. The flat belt, as shown in Fig. (a),…
Types of Belt Drives
The belt drives are usually classified into the following three groups: 1. Light drives. These are used to transmit small powers at belt speeds upto about 10 m/s,as in agricultural machines and…
