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.

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.

STANDARD PENETROMETER

Description:

Used to determine grade of bitumen. The penetration tests determine consistency of bitumen for the purpose of grading. Depth in units 1/10 of millimeter to which a standard needle having a standard weight 0 will penetrate vertically in a duration of five seconds at a temperature of 25 C determines penetration for gradation.

Specification:

It consists of a vertical pillar mounted on a base provided with leveling screws.

The head, together with dial plunger rod and cone (or needle) slides on a pillar and can be clamped at any desired height.

A rack and pinion and pointer assemble provides fine adjustment of needle or cone tip to sample. It incorporates a clutch mechanism which makes reading of penetration and subsequent resetting a simple and accurate operation.

The dial is graduated in 400 1/10 and the millimeter subdivisions and the needle pointer against figures makes easy reading. Supplied with a bitumen penetration needle, ring weight one each 50gms and two sample containers.

MOTORIZED GYROSCOPE APPARATUS MAKE : CREATIVE LAB MODEL NO: CLTOM-05

DESCRIPTION:

The set up consists of stainless steel disc mounted on a horizontal shaft, rotated by a variable speed motor. The rotor shaft is coupled to a motor mounted on a trunion frame having bearings in a yoke frame, which is free to rotate about vertical axis. A weight pan on other side of disc balances the weight of motor. Rotor disc can be move about three axis. Torque can be applied by calculating the weight and distance of weight from the centre of rotor. The gyroscopic couple can be determined.

EXPERIMENTATION:

Experimental justification of the equation T = I. . p. for calculating the gyroscopic couple by observation and measurement of results for independent vibrations in applied couple T and precession p.

To study the gyroscopic effect of a rotating disc.

UTILITIES REQUIRED

Electricity Supply : 230 V AC, Single Phase, 0.5 kW

Bench area : 1m x 1m

Digital Tachometer

TECHNICAL DETAILS:

Disc : Material Stainless Steel, Dia 300 mm x 10 mm thick precisely balanced which can be rotated in 3 mutually perpendicular axis.

Motor Variable speed of standard make.

Supplied with Speed Control Unit.

Weights2 kg, 1 kg, 500 gms.

Stop Watch Electronic

Accurately marked scale & pointer to measure precession rate.

Instruction Manual : An ENGLISH instruction manual will be provided along

With the Apparatus.
