In many applications the pulley has more than one groove and there are obviously an appropriate number of belts.
Belt and rope drives.
Rope drives use a number of circular section ropes rather than a single flat or vee belt.
Are used for power transmission.
Flywheel and rope drum of the large mill engines victoria and alexandra at ellenroad mill multiple rope drive.
The rope drive is widely used where a large amount of power is to be transmitted from one pulley to another over a considerable distance.
A rope drive is a form of belt drive used for mechanical power transmission.
Rope drive do not mistaken with round belt is used where a large amount of power is needed to transfer for a long distance more than 8m.
The belt drive is an essential component to the invention of the spinning wheel.
It can be used for long distance.
Rope drives use a number of circular section ropes rather than a single flat or vee belt.
To transmit power from one shaft to another pulleys are mounted on the two shafts.
Mechanical elements like friction disc various types of belts rope chain gears couplings etc.
The rope runs over a grooved pulley.
Advantages of the rope drive.
Assuming that the included angle of the groove is the normal reaction is given by.
