Cam Analysis Machine(TOM-02 )

Apparatus is a motorized unit consisting of a camshaft driven by a variable speed motor. The shaft runs in a double bearing. The free end of the camshaft has a facility to mount the cam easily.

The follower is properly guided in gunmetal bushes and the type of follower can be changed according to the cam under test. Graduated circular protractor is fitted co-axial with the shaft. And a Dial Gauge fitted on the follower shaft is used to note the follower displacement for the angle of cam rotation. A spring is used to provide controlling force to the follower system. Weights on the follower shaft can be adjusted as per the requirement. An arrangement is provided to regulate the speed. The apparatus is very useful- for testing the cam performance for jump phenomenon during operation. On this apparatus the effect of change of inertia forces on jump action of earn-follower during operation can be observed. It is useful for testing various cam & follower pairs. Three cams and three followers will be supplied with the apparatus. Theses are already hardened to reduce the wear.

Experiments

With the help of combination of provided cams and followers following experiments can be conducted:

  • To plot the n-Q (Follower displacement Vs Angle of rotation) curves for different cam follower pairs
  • The follower bounce can be observed by using a stroboscope (Optional) & effect of follower weight on bounce can be studied.
  • To study the effect of follower weight on bounce
  • To study the effect of spring compression on bounce
  • The tests can be repeated by changing compression springs, follower weights and cam speed.

The apparatus consists of a pad, which can be tilted to the required angle. An endless belt, which moves, beneath the pad, carries the oil over its surface from oil bath. When the pad is tilted over the oil film, pressure is developed, the pad is provided with pressure tapings parallel and perpendicular to belt direction. The pressure distribution is measured over a multi tube manometer. A variable speed motor drives the belt. The tilting angle and minimum gap between pad and belt can be adjusted and characteristics thus can be studied at various gaps, inclination and relative surface speeds.

Experiments

  • Demonstration of pressure development
  • Plotting pressure variation curve in longitudinal & transverse direction of a pad for various speeds and pad inclination
  • Demonstration of cavitations phenomenon

Utilities Required

  • Power Supply: 230 V AC, Single Phase.
  • Floor space: 1m x 1.5 m (approx).
  • SAE-40 oil for carrying the test (approx 3 Ltrs.)

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.

Experiments

  • 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

Epicyclic Gear Train & Holding Torque App  (TOM-11 )

Gear Train is any combination of gear wheels by which motion is transmitted from one shaft to another shaft. In Epicyclic gear trains, the axes of shafts on which the gears are mounted may move relative to a fixed axis. It is a motorized unit consisting of a SUN gear mounted on input shaft. Two plane gear meshes with the annular gear. These planet gears are mounted on a common arm to which output shaft is fitted. Loading arrangement is provided for loading the system and to measure holding torque.

Experiments

  • To measure Epicyclic gear ratio between input shaft and output shaft (Actual and Theoretical),
  • To measure input torque, holding torque and output torque.

Utilities Required

  • Power Supply : 220 V AC, Single Phase.
  • Floor Area:1.5 x 2 m.
