SLIP and CREEP MEASUREMENT APPARATUS

Product Code: JL--2679

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    o    0.5 kW, 220 V, Single Phase
·         Stroboscope.
TECHNICAL DETAILS:
·          Motor   o    Variable speed DC Motor 1HP, 1500 RPM.
·         Pulleys   o    Driving and driven pulleys of equal diameters (flat pulleys)
·         Loading Arrangement   o    Brake drum along with spring balance and rope arrangement is provided to load the system.
·         Belts    o    Flat belts of fixed length of following belt material
§  Fabric Belt
§  Canvas Belt
§  Leather Belt
·         Belt tightening arrangement   o    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
