Description

The Overdrive Unit has been designed to demonstrate the action of the gear elements in simple epicyclic gear arrangements. The unit may also be used by students in the laboratory to carry out simple experiments on epicyclic gearing.

The apparatus illustrated has been designed specifically for Motor Vehicle courses and represents an application of a simple epicyclic arrangement of the type used in a motor vehicle overdrive.

Pulleys fitted with protractors are secured to the input and output shafts to enable the student to determine and verify velocity and torque ratios.

The unit may be wall mounted or attached to a Universal Bench Mounted Frame (Ref SD-1.10).

The apparatus is designed so that the overdrive can be coupled to the Gearbox (Ref SD-1.15) and Differential (Ref SD-1.16) to represent a simple transmission system.
