The THEORY of MACHINES range enables clear and comprehensive learning of and topics. An understanding of the way in which forces act and react, is fundamental when studying the application of loads on a variety of fixed structures and rotating machinery. The THEORY of MACHINES form a comprehensive range of equipment, equally suitable for demonstration and experimental work.

All the THEORY of MACHINES hardware operates in a standalone mode, with a large number being supplied with Data Acquisition Software.

HTM98 Single Epicyclic Gear Train

The gear train consists of a sun gear in the centre, three planet gears, a planet linkage and an internal or ring gear. The sun gear, ring gear and planet carrier all rotate about the same axis. The planet gears are mounted on shafts that turn in planet carrier and meshes with both the sun gear and the ring gear.

Pulleys fitted with protractors are attached to the input and output shaft so that torque and velocity ratios may be determined. Torques can be applied to the shaft by adding weights on cords wrapped on the pulleys. By Locking pins are used to holding different parts of the apparatus in position. This gives the user different options on gear ratios that can be applied between the input and output shafts.
