Full Specification ( Epicyclic Gear Train Holding Torque Apparatus ):
Epicyclical Gear Train and Holding Torque Apparatus
It consists of two types of Epicyclic gear trains viz. External type & Internal type.
[I] External Type Epicyclic Gear Train:
It is a hand driven demonstration model consisting of two bearing blocks, supporting input and output shafts through the epicyclical gear train. The input (driving) shaft carries an arm and pin on which the compound gear wheel is free to revolve and it meshes with the fixed wheel and the wheel is keyed to he output (driven) shaft.
[II] Internal Type Epicyclic Gear Train:
It is a motorized unit consisting of SUN gear mounted on input shaft. Two plane gears mesh with the annular gear. These planet gears are mounted on a common arm to which output shaft is fitted. Loading arrangement is provided for loading the system and to measure Holding Torque.
Specifications:
v External type Epicyclic Gear Train:
1. Bearing blocks for input & output shafts.
2. A gear train with Holding drum and handle.
v Internal Type Epicyclic Gear Train:
1. A compact Gear Train.
2. Variable speed D.C. Motor
3. Rope brake arrangement to measure output torque and holding torque.
v Control Panel comprising of
1. Digital Ammeter and Voltmeter.
2. RPM Indicator.
