Manufacturer, Exporter & Supplier of Demonstration Gear System Model
Description
A series of models to demonstrate different gearing systems. With
transparent slideplates, the gears may easily be seen and where
necessary there is an index on the primary and secondary shafts to show
the change in the direction of rotation and the relative speed of
rotation. A simple three-speed and reverse-gear system using spur gears.
Reverse gear is obtained by interposing a small lay-shaft mounted
pinion between the two main shafts. Gear selection is by means of a
short ball-ended lever.
