Product Description

Descreiption of 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 Spur Gear Lifting Machine 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.

Experimental Capabilities of Spur Gear Lifting Machine

 

  1. To determine the 'EFFORT' for a range of applied loads
  2. To determine the effect of friction for a range of applied loads
  3. To determine the efficiency for a range of applied loads
  4. To establish the law of the machine and the limiting value of its efficiency
  5. To compare the results with the machine set up with single and double purchase
  6. To compare the experimental results with calculated values
