HTM11 Spur Gear Lifting Machine

HTM11 Spur Gear Lifting Machine

A vertical stand incorporates a back plate which carries a number of spur gears on shafts to enable single, double or three stage gear trains to be assembled. The pulleys mounted to some of the gears can be used for either single or double purchase experiments.

The three (3) spur gears supplied include a driver having 40 teeth, a driven wheel with 120 teeth and an intermediate gear of 40/120 teeth compound.

The lifting machine can be set-up as a two gear or three gear train. The driver and driven wheels have integral pulleys around which cords are wrapped to act as 'EFFORT' and 'LOAD'. Cords, hangers and a set of weights are included to provide drive to the gear trains and to determine ratios, mechanical advantage and efficiency.

A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
