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,

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.

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

STATIC & DYNAMIC BALANCING DEMONSTRATOR MAKE : CREATIVE LAB MODEL NO:CLTOM-04

DESCRIPTION:

This equipment is designed for carrying out the experiment for balancing a rotation mass system. The apparatus consists of a stainless steel shaft fixed in a rectangular frame. A set of four blocks with a clamping arrangement is provided. For static balancing, each block is individually clamped on shaft. For dynamic balancing, a moment polygon is drawn using relative weights and angular and axial position of blocks is determined. The block are clamped on shaft is rotated by a motor to check dynamic balance of the system. The system is provided with angular scale and is suspended with chains for dynamic balancing.

EXPERIMENTATION:

To balance the masses statically and dynamically of a single rotating mass system.

To observation of effect of unbalance in a rotating mass system.

UTILITIES REQUIRED

Electricity Supply : 220 V AC, Single Phase, 0.5 kW with earth

Floor Area 0.5m x 0.5m

Digital Tachometer

TECHNICAL DETAILS

Drive Motor FHP Motor, variable speed, with speed controller.

Balancing weight 4 Nos. of Stainless Steel with different sized eccentric mass for varying unbalance.

Rotating Shaft Material Stainless Steel

Instruction Manual An ENGLISH instruction manual will be provided along With the Apparatus.
