Simple Geared System
The system is for studying the acceleration of a gear system under different gear ratios.
The system consists four parallel shafts with fix and sliding gear and supported by ball bearings on a base frame. Shafts 1, 2 and 3 have two fixed gears. Shafts 2, 3 and 4 have two sliding gears. Each pair of adjacent shafts has two transmission ratios, providing 8 different gear ratios between the first and the last shaft. Inertia mass with torque drum is attached to each shaft. A cord wound around a drum and the weight hanger provides a means of applying a torque. The gear system is attached to a wall supported on two legs for weight hanger travel. By timing the fall of the weight hanger, the acceleration of the system can be calculated. A sprocket and lock pin, and a winding handle are provided for raising the weights. All gears are enclosed in a casing with a transparent cover for safety.
Instruction manual is also included.

Machine Elements and Theory of MachinesComprehensive Geared System
The apparatus is used for studying the acceleration of a geared system as well as geared system efficiency under different gear ratios.
The system consists of three shafts, two stage spur gear unit with two fixed gear and two sliding gear sets. All shafts rest on ball bearings on a steel frame.
The first shaft has a cable drum for weight hanger.
The second shaft has an interchangeable inertia mass. A speed sensor monitors the mass speed at four pulses per revolution.
A motor dynamometer measures the gear system input power. This motor dynamometer drives the first shaft via an electric clutch. Speed is controlled by an inverter.
A mechanical brake dynamometer is attached to the third shaft for measurement of the gear system output power.
For a study of acceleration of the geared system, a weight hanger provides torque on the cable drum and speed sensor can measure inertia mass velocity and acceleration.
The apparatus has a transparent cover with interlocks for safety protection.
Instruction manual is also included.

Machine Elements and Theory of MachinesStatic and Dynamic Balancing Machine: Computer interface
The machine is used for studying of balancing principles.
A rotor shaft is connected to the motor by a double universal joint and rests on two supports with adjustable distance between supports. Each support holds the shaft in place by three bearings with crest. Two standard rotors and two radially slotted rotors are provided for various cases of balancing. The unbalance forces are picked up by two vibration transducers and converted to digital signals. The speed is adjusted by an inverter and speed signal is provided by a sensor. The magnitude and angle of the unbalance for each plane is analyzed and displayed on a computer (separately supplied). The vibration and speed transducers are removable for field use. A note book computer is recommended for field use but is not included in the scope of supply. A transparent cover is provided for safety.
Instruction manual is also included.
