Belt Drives

Hi and welcome to all students!

As you were informed, click the link below to find information on  belt drive.


BELT DRIVES

BELT DRIVES PRESENTATION

What is a belt?
A belt is a looped strip of flexible material used to mechanically link two or more
rotating shafts. A belt drive offers smooth transmission of power between shafts
at considerable distance. Belt drives are used as source of motion to transfer to
efficiently transmit power or to track relative movement.

TYPES OF BELT DRIVES BASED ON ARRANGEMENT:
Types of Belt drives based on the arrangement are as follows
OPEN BELT DRIVES
CROSSED OR TWIST BELT DRIVES
BELT DRIVE WITH IDLER PULLEYS
COMPOUND BELT DRIVE

OPEN BELT DRIVE

  • The Open belt drive is arranged with shafts arranged parallel and rotating in the same direction.
  • The driver pulls the belt  from one side and delivers it to the other side thus the tension in the one side belt will be more than that in the other side belt.
CROSSED BELT DRIVE

  • The crossed  or twist  belt drive is used with shafts arranged parallel and rotating in the opposite directions.
  • The tension in the tight side will be more than the slack side. The point where the belts rubs against each other and there will be excessive wear and tear.
  • To avoid this the shafts should be placed at a maximum distance of 20b where b is the width of the belt and the speed should be less than 15 m/s.

COMPOUND BELT DRIVE


  • A compound belt drive is used when power is transmitted from one shaft to another through a number of pulleys.
  •  The belts are connected in such a way that the driver moving one system of drives is simultaneously moving the other connected system.
IDLER PULLEY
1) Adjust tension and slack in the belt
2) Increase the belt contact area with pulley

3) To make drive compact
