HTM98 Single Epicyclic Gear

HTM98 Single Epicyclic Gear Train

The wall mounted Single Epicyclic Gear Train consists of a single stage epicyclic gear train for laboratory demonstration of gear system similar to ones used in automotive applications.

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.

Bearings are used in the entire unit to minimize friction losses.

The apparatus can be operated in one a variety of modes. 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. By changing the combinations between the epicyclic gear parts a wide range of ratios and different output directions can be produced.

The apparatus is supplied with all calibrated weights and load hangers necessary to operate the apparatus.

The apparatus comes with a comprehensive instruction manual for student and lecturer as well as a 2 year warranty.
