Transmission Driving "Large" Gears - Clip Two

The two large gears are being driven by a microengine operating at 6000 RPM. The transmission has been driven at speeds as high as 60,000 RPM.

Spring Device

Here a spring device is wound and unwound. Perhaps one day a micro-clock can be made with this type of mechanism.

Torque Demonstration

This is a microengine driving a gear approximately 40 times its own diameter, demonstrating the large torque it can produce.

Microengine and Gears

This microengine's drive gear is turning a 250-tooth gear more than 10X as large as itself. The speed of the drive gear is 600 RPM, and it has been operated as fast as 60,000 RPM.

Microengine, Transmission, and Spring Device

This video pans from the microengine driving the device, through a transmission that multiplies the torque, to a spring that winds-up and drives additional gears.
