The apparatus consists of a variable speed D.C. Motor, driving pulley and driven pulley of equal diameters. The driven pulley can slide on the base only with bearing block to change the initial tension in belt. Brake drum is mounted on the output shaft, which helps to measure power output. The pulleys are mounted on input shaft (motor shaft) and output shaft. Brake drum is mounted on the output shaft, which helps to measure power output. With the help of Stroboscope (not in the scope of supply) it is possible to demonstrate the slip of belt on driving and driven pulley. The motor speed is varied by Thyristor Control D.C. Drive. A double channel digital speed indicator indicates driving and driven pulley speeds. Belt slip or creep also can be measured. 

Technical Details:-

 

•  Motor: Variable speed DC Motor 1HP, 1500 RPM.

•  Pulleys: Driving and driven pulleys of equal diameters (flat pulleys).

•  Loading Arrangement: Brake drum along with spring balance and rope arrangement is provided to load the system.

•  Belts: Flat belts of fixed length of following belt material.

•   Belt tightening arrangement: Bearing block is sliding and dead weight can be applied to set the initial tension in belt.
