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.

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.

MICHELL TILTING PAD BEARING APPARATUS MAKE : CREATIVE LAB MODEL NO: CLTOM-09

DESCRIPTION:

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. The belt is driven by a variable speed motor. 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.

EXPERIMENTATION:

Demonstration of pressure development.

Plotting pressure variation curve in longitudinal & transverse direction of a pad for various speeds and pad inclination.

Demonstration of cavitation phenomenon.

UTILITIES REQUIRED:

Electricity Supply: 230 V AC Single Phase 50 Hz 5-15 amp combined socket with earth connection.

Earth voltage should be less than 5 volts.

Floor area: 1.5 m x 1.0 m (approx).
