Strain Wave Technology
Flex gear and elastic bearing take elliptic shape with cam inserted.
Elliptical cam input is inserted into Flex gear and then mounted into internal gear; the flex gear engages the internal gear in 2 locations 180˚apart. This allows for high torque in a compact stable manner.
With internal gear fixed and cam (input) rotated clockwise, the flex gear (output) rotates counter clockwise. Direction and speed of rotation is determined by tooth count of gears and mounting geometry.
