PIN ON DISC WEAR APPARATUS
DESCRIPTION 
The Pin and Disc wear Apparatus consists of a steel disc whose top surface is case hardened and
ground. The disc is rotated by a single ph. Induction motor at 3 different speeds. The test pin is
inserted in a pin guide so that one end of pin touches the rotating disc. The pin guide is mounted on a cantilever to which spring balance is attached. The pin is inserted in the pin guide. The disc is set to rotate at the required speed. Load is put over the pin and wear of the pin is measured.
TECHNICAL DETAIL
DISC - Case hardened steel disc,
Dia. 200 mm
Max speed 2700 rpm.
Max. surface speed 26.5 m/s.
Driver motor - 1 HP, 2800 rpm,
Single ph. Induction motor with 3 speed V â belt pulley.
Pins -Dia. 12 mm + 0.000 / -0.005 mm,
Aluminium, brass and cast iron â“1 No. each, with pin guide.
Lubricant tank with pipe for lubricated testing.
Spring balance 1 kg.
Analogue displacement measurement unit for measurement unit for measurement of wear of pin,
range â 0-10 mm, L.C. 0.01 mm.
A splash arrester and protective cover are provided around the disc.

CAM ANALYSIS APPARATUS MAKE : CREATIVE LAB MODEL NO:CLTOM-02
DESCRIPTION                                                             
The setup is a motorized unit consisting of a camshaft driven by a variable speed motor. 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 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 and the effect of change of inertia forces on jump action of cam-follower during operation can be observed. Three sets of cams and followers are supplied with the apparatus. These are already hardened to reduce the wear. With the help of combination of provided cams and followers following experiments can be conducted:
EXPERIMENTATION:
To plot the(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.
UTILITIES REQUIRED
Floor Area  0.5 m x 1 m
Electricity Supply 220 V AC, Single Phase, 0.5 kW

WHIRLING OF SHAFT DEMONSTRATOR
DESCRIPTION:                                                                    
The set up is designed to study the whirling of shafts. The set-up consists of a sturdy frame, bearing holders, variable speed motor etc. to drive the shaft along with speed control unit.  Different bearing can be fitted in bearing block to have different end conditions i.e. (i) both end fixed, (ii) one end free and one end fixed etc. As the test is destructive, hence the shaft can not be used again.
EXPERIMENTATION:
Display of various modes of whirl for a shaft with
Both ends directionally fixed.
One ends fixed and other free
Both ends directionally free.
Modes of vibrations can be studied and frequency can be measured in each case.
UTILITIES REQUIRED
Floor area of 2m x 0.5 m.
Electricity Supply 230 V AC, Single Phase, 0.5 kW.
Digital Tachometer
TECHNICAL DETAILS
Test Shafts
Length 1000 mm each.
Diameter 3.2, 4.8 & 6.4 mm (approx.)
Quantity Two each.
Kinematic coupling bearing for fixed or free ends without restraint.
Drive motor, 5000 rpm, FHP.
Supplied with a speed control unit.
Instruction Manual An ENGLISH instruction manual will be provided along  with the Apparatus
