Slip and Creep Measurement Apparatus

To measure belt slip speed and observe the limited value of load constant speed when the slip Just starts. The motor speed is varied by Thyristor Control D.C. Drive. A double channel digital speed indicator indicates driving and driven pulley speeds. 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. Used in major experimental applications, this range is inclusive of very salient features. Scope Of Experimentations: To measure co-efficient of friction between pulley material and different belt materials To measure power transmitted with varied belt tension To measure percentage slip at fixed belt tension by varying load on the Brake drum and plot the graph of (T1-T2) v/s percentage slip i.e.

“Slip Characteristics” Finding a Creep Zone from graph To measure belt slip speed and observe the limiting value of load at constant speed when the slip just starts To study creep of belt Utilities Required: Electricity : 0.5 kW, 220 V, Single Phase Stroboscope 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 like Fabric Belt, Canvas Belt,

Leather Belt Belt tightening arrangement : Bearing block is sliding and dead weight can be applied to set the initial tension in belt Speed Indicator : 2 Channel digital speed indicator with switch to change the channel
