Which of the following is not a function of thin continuous line in Technical drawing?
The following are Types of Line in Technical Drawing EXCEPT _____.
The belt drives are frictional drives that transmit mechanical energy on a dry surface from one shaft to another in a pulley-like system. An instance of a belt drive is shown in the image below.
For the belt drive to work properly, both sides of the shaft must be dry and separated by some distance.
Note: Either shafts (also referred to as the pulleys) on which the belt drives are attached do not necessarily need to rotate at the same speed; neither must they be of the same size.
The tension between both sides of the belt will depend heavily on the angle of contact. To this end, the tight side of the belt drive is always below while the slack (or loose) side stays above. They are shown in the image below.
The area of belt having a lesser tension (less tightly stretched) is generally referred to as the slack side while that having a higher tension (more tightly stretched) is termed the tight side. You can think of tension as the level of tightness at which something is stretched.
In belt drives, mechanical power is usually transmitted from the driving pulley to the driven pulley via a rotational motion. Since belt drives are used in conjunction with pulleys; some of the mechanisms or machines that utilizes belt drives include:
The belts used in machines utilizing the belt drive system can be of the following types:
Note: Materials used in making the various kinds of belt drives include rubber, plastic, fabric, leather and other synthetic materials.
