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 shafts has a cable drum for weight hanger.
The second shaft has an interchangeable inertia mass. A speed sensor monitors the mass speed.
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. The unit is steel frame with adjustable footings.
TYPICAL EXPERIMENTS
- Inertia of a mass and of a geared system.
- Input power, output power, and efficiency.
- Effect of speed and load on efficiency.
