Result?

Bosch.. gearbox.. go.. "boom".

This gearbox was rated for a Bosch drill motor that had about 400 watts with an input speed of up to 20,000 rpm. The pic would show 2 motor setup (more power) with a dramatic reduction in input speed. This input speed is driven by an very large torque.

This gearbox setup would work ok until the output shaft of the Bosch gearbox was resisted from movement (most likely used on an arm, and the arm hits something un-moveable). Once this happens, those little gears in the Bosch gearbox would be turned to dust.

This pic shows a fairly simple way to blow up a Bosch gearbox. Wear your safety glasses!
