Special gearboxes show their workings

Ondrives of Chesterfield has recently made two special gearboxes for a well-known pharamaceutical company, which are unusual in one particular aspect.

Ondrives of Chesterfield has recently made two special gearboxes for a well-known pharamaceutical company, which are unusual in one particular aspect.

The client wanted to present two gearboxes to its current students for teaching purposes that would show how internal gearings worked in both an epicyclic arrangement and a spur reduction box.

In order to show how these internal mechanisms work, the gearboxes were made with a clear Perspex casing allowing a good view of the meshing gear teeth.

On the spur reduction box, the highest possible ratio of 500:1 was chosen so that a number of different gears would be moving at the same time showing the possibilities of this type of box in a high ratio.

Both gearboxes have been specially mounted onto mahogany plinths so that the tutor in question can keep them on his desk for posterity.
