* Impressive demonstration of the relationship between the number of gear teeth and the transmission ratio of gear trains

Sci-tech Motorized Gears Train Model MT 040 conveys the relationship between the number of gear teeth on spur gears and the transmission ratio of gear trains. The unit consists of a metal base plate with a fixed axle and a rail made of steel. Two further axles can be clamped to the rail in any position. In this way it is possible to construct one and two stage gear trains with any combination of gears. By undoing a locking pin, the rail can be swiveled around the fixed axis providing a demonstration of planet gear trains. Drive pins couple the gears. Four metal gears are included with the unit. The motorized shaft enables rotation in clockwise or anti-clockwise direction.
