Slip and Creep Measurement Apparatus in Belt Drive
Item code: ETE-2112
This apparatus is useful for measurement of power transmitted for various input power conditions with varied belt tension. Belt slip or creep also can be measured. The apparatus consists of a variable speed D.C. Motor, driving pulley and driven pulley of equal diameters. The pulleys are mounted on input shaft (motor shaft) and output shaft. 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 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.
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
a) Test rig consists of a gear pump of size 25mm.x 25mm. coupled to an 1 HP AC Motor and fitted on a rigid iron stand made of M.S. angles. Oil circulates in a closed cycle from an M.S. reservoir tank of size 100 liters. through the pump to an M.S. collecting tank of size 45 liters. The tanks are provided with gauge glass scales and are fitted to the stand to form a compact unit. Suitable pipe lines with pressure and vacuum gauges connect the pump suction line to the reservoir and delivery line to the collecting tank. A modified gate valve to prevent accidental complete closure is provided in the delivery line to control delivery pressure. b) Other standard accessories include switch, stopwatch and energy meter.

The new Plantar Test Instrument (Hargreave’s Method) measures response to infrared heat stimulus.
Focus the infrared source below the Plantar surface and with the press of a button … latency to paw withdrawal and infrared intensity are recorded automatically (i.e. no manual scoring!). Classically the measurement of acute nociceptive thermal threshold in laboratory animals has primarily relied upon the tail flick and hot plate methods. Although both methods are still used frequently in pharmacological studies, they are not without limitation. In addition, neither method has been extended to investigating behavioural responses to hyperalgesia. The Plantar Test represents a remarkable advance in methodology, as it combines the best features of all other methods of measuring pain sensitivity. Unique to the Plantar Test, the animal is unrestrained during experiments. Moreover, time latency is recorded automatically by a fiber optic sensor, without having to rely on the experimenter observation of the animal behaviour. Data appear on the front panel and may be exported to a memory stick, or to computer via USB; software is included.
