  Comprehensive 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.
