1. MAKIT – Master Kit

Makit - Master is a collection of precision mechanical components which are handy & flexible. These components can be used for building Mechanisms like slider crank, whit worth quick return mechanisms, walking mechanisms and pantograph copying mechanisms and so on. By utilizing these components anybody can build verities of machine prototypes & later on it can be transformed in to real working models. These comprehensive components has wide verities of Machine elements & there is lot of room for the testing of creative ideas and even one can even draw the coupler curves with the help of pencils and drawing boards provided in the kit. Which will be useful for doing lot of research work regarding the mechanisms and their movements instantaneously Makit - Master is an asset to kinematics, Mechatronics & Robotics lab's to carry out all types of project works, experiments & research work using various kit components like links, shafts, spur gears, bevel gears, couplings, etc,.

2. Epicyclic Gear Train Apparatus

Any combination of gear wheels by means of which motion is transmitted from one shaft to another shaft is called a gear train. In case of epicyclic gear trains, the axes of the shafts on which the gears are mounted may move relative to a fixed axis. This experimental apparatus consists of sun and planetary gear box with a sun gear (14 teeth) and two planet gears (21 teeth each), rope and spring balance arrangement to measure output torque and holding torque, 1 H.P. D.C. shunt motor, 3000 RPM, 230 V, control panel with dimmerstat (DC) for speed variation and ammeter and voltmeter.

3. CAM Analysis Machine

The machine is a motorized unit a camshaft is driven by a D.C. Motor. The shaft runs in a double ball bearing. At the end of the cam shaft a cam can be easily mounted. As the follower is properly guided in gun- metal bushes and the type of the follower can be changed to suit the cam under test. A graduated circular protractor is fitted coaxial with the shaft and a dial gauge can be fitted to note the follower displacement for the angle of cam rotation. A spring is used to provide controlling force to the system. Weights on the follower rod can be adjusted as per the requirements. An arrangement is provided to vary the speed of camshaft. The machine is particularly very useful for testing the cam
performance for jump phenomenon during operation. The machine clearly shows the effect of change of inertia forces on jump action of cam follower during the operation.

4. Static & Dynamic Balancing Machine

The apparatus consists of a steel shaft mounted in ball bearings in a stiff rectangular mainframe. A set of four blocks of different weights is provided and may be detached from the shaft. A disc carrying a circular protractor scale is fitted to one side of the rectangular frame. A scale is provided with the apparatus to adjust the longitudinal distance of the blocks on the shaft. The circular protractor scale is provided to determine the exact angular position of each adjustable block. The shaft is driven by electric motor mounted under the main frame, through a belt. For static balancing of weights the main
frame is suspended to support frame by chains then rotate the shaft manually after fixing the blocks at their proper angles. It should be completely balanced. In this position, the motor driving belt should be removed. For dynamic balancing of the rotating mass system, the main frame is suspended from
the support frame by two short links such that the main frame and the supporting frame are in the same plane. Rotate the statically balanced weights with the help of motor. If they rotate smoothly and without vibrations, they are dynamically balanced.

5. Balancing of Reciprocating Masses Apparatus

The apparatus is designed to demonstrate the effect of unbalanced mass in reciprocating motion. The apparatus consists of a simple cylinder, piston and connecting rod arrangement. The piston, driven by the motor, reciprocates in the cylinder. The motor is coupled with connecting rod. Speed of the motor can be varied with the help of dimmerstat. Initially the total system is in completely balanced condition. That is, the piston is reciprocating smoothly in the cylinder without extracting any extra current from the motor. This can be visualized on the ammeter. If the system is made unbalanced by putting some extra weight on the piston, immediately it will start to extract extra current from the motor. This change in current can be observed on the ammeter. The speed of the connecting rod can be measured by using RPM indicator.
