EXPERIMENT NO. 01

EPICYCLIC GEAR TRAIN & HOLDING TORQUE APPARATUS

Introduction:-

Any combination of gear wheels by means of which motion is transmitted from one shaft to

another shaft is called as gear train. In case of Epicyclic Gear – Train the axis of the shaft on

which the gear are mounted may move relative to a fixed axis. In this apparatus internal type

(Experimentation model) Epicyclic Gear – Train is demonstrated.
DESCRIPTION

Internal Epicyclic Gear Train :-

It consists of SUN gear mounted on the input shaft. Two planet gear are on the both side

meshes with SUN gear and which also meshes with the internal teeths of the annual gear.

Two planet gear are mounted on the pins which are fitted into both ends of the arms. Output

shaft is connected to the arm on which drum is fixed.
SPECIFICATION


  1. Epicyclic Gear-train.

  2. Belt / rope and spring balance arrangement to measure output torque and holding torque.

  3. 1 H.P.D.C. shunt motor, 1500 rpm, 230 v, 4 Amp.

  4. Control panel with dimmer (DC) for speed variation and ammeter and Voltmeter to get

Input power, RPM indicator.

  1. Internal Epicyclic Gear.
