About This Product
The sun gear sits on the input shaft, and two planet gears meshing with the annular gear are carried on a common arm fitted to the output shaft. Loading the system lets students measure the gear ratio between the input and output shafts and between the input shaft and the holding drum, along with input, holding and output torque. Among engineering educational equipments in India for gear-train studies, this THEORY OF MACHINE LAB apparatus pairs an external type and an internal type epicyclic train.
Frequently Asked Questions
Q1. What can be measured with this apparatus?
The epicyclic gear ratio between the input and output shafts, the gear ratio between the input shaft and the holding drum, and the input, holding and output torques.
Q2. How is holding torque measured?
A loading arrangement loads the system, and the rope brake arrangement measures both the output torque and the holding torque.
