67 p p t b v 1000 where p p is the power to drive pulley kw t b is the belt tension n and v is the belt speed ms.
The power transmitted by a belt drive is given by. This method is good for delivering more power as the belts rupture very less when compared to other methods of. Power to drive pulley. The belts and ropes are used where distance between the two shafts is large.
Determine the effect of power transmission in the following cases. Which is maintained due to frictionand hence. The balance of forces on a pulley generally shows that the difference between the tight side force ft and the slack side force fs corresponds to the transmitting circumferential force fc.
An endless belt. The power is transmitted from one shaft to the another shaft by a belt chain and gear drive. The power required to drive pulley can be calculated from the belt tension value as.
Power transmission of belt drive this circumferential force fc causes different forces on the two belt sections and a tight side and a slack side will form. If the maximum tension in the belt is 3000 n. Arrangement of belt drive 1 open belt drive 2 closed belt drive 13.
Of pulley d 120 cm 12 m speed of pulley n 200 rpm. A belt drive consists of two parallel shafts and a pulley is mounted on each shaft. This makes the driven pulley rotate in the same direction as that of the driver pulley.
The angle of lap on the smaller pulley is 165. Power transmission by belt drive is one of the most common and universally used methods of transmission system when two shafts are parallel up to 10 m to each other as shown in fig. Problem 1 based on belt drive power transmission theory of machine duration.
The chains are used for. Ekeeda 170934 views. Open belt drive in this type of arrangement the belt is put up on both the pulleys straightly without any twist or turns.
25 kw of power transmitted by an open belt drive. An open belt drive connects two pulleys 120 cm. Equations for power transmitted by a flat belt drive ask question asked 1 year 10 months ago active today viewed.
The linear velocity of the belt is 25 ms. A basic course in engineering mechanics would suggest that the power transmitted by a belt drive is a function of difference in tension between the slack and the tight side.
