Universal Governor Apparatus
The set up consists of a small electric motor
connected bevel reduction gear box or belt and pulley system through a
flexible coupling. The Governor spindle is driven by a solid coupling
connected to the gear box output shaft and is supported on ball bearing. The
optional governor mechanism can be mounted on spindle. Speed control unit is
provided to regulate speed and extension to the spindle shaft can be sued to
use hand tachometer. The center sleeve to the porter and proell governors
incorporates a weight sleeve to which weights are added. The Hartnell
Governor can be operated as a stable or unstable Governor. The following
range of experiments can be
- The effect of varying mass of the center sleeve.
- The effect of varying the rotating mass.
- Determination of characteristic curves of sleeve position against
speed of rotation. The effect of varying the initial spring compression.
Static And Dynamic Balancing Apparatus
This is suitable for conducting experiments on
static balancing and dynamic balancing with different weights. This consists
of rectangular frame of steel perfectly balance with four different blocks.
A protractor scale of the disc is provided to reach exact angular position
of each weight to be measured. A linear scale provided below the frame
provides the measurement of each weight along the shaft. The unit is hanging
from a rigid steel frame through chain for dynamic balancing and can be
fixed rigidly for static balancing.specified in the IS 2386 (Part I).
Cam Analysis Apparatus
The machine facilitates the study of dynamic
behavior of cam follower. It consists of a DC Motor coupled to an extension
shaft whose and carries a cam. A cam follower, mounted on the end of a
vertical bar, is loaded on the cam face by compression spring is retained by
a cross bar mounted on two vertical pillars attached to the base plate.
Facility is provided to vary the pre compression of spring. The inertia of
follower can be altered using weights.
Motor is provided only to demonstrate the actual
water of system. However while drawing the graph the motor shall be rotated
by hand only.
This is to demonstrate the relationship between
applied torque and the rate and direction of rotation. This is motorized and
mounted on a frame such that free to rotate about three perpendicular axis.
This facilitates to observe the laws of stability and justification of
Whirling Of Shaft Apparatus
This compact and simple apparatus incorporated two
features. Firstly, kinematics coupling at the driven and of the shaft to
slide freely in longitudinal direction while revolving readily. The
directional clamping of this end of the shaft is achieved by and
interchangeable chuck without self aligning radial ball bearing.
The shaft is driven through a dynamically balanced flexible coupling by a
universal motor, the speed of which can be controlled by a control unit. The
speed of rotation of the shaft can be measured by a stroboscope. Tachometer
can be also used for speed measurement. The following shafts made from steel
will be supplied.
