Abstract

An enveloping worm transmission is suitable for the transformation of motion and power between an enveloping worm (29, 33 or 35) and a worm gear (30), (34 or 36) wherein the axis of the worm gear and the enveloping worm may be crossed, parallel or intersected. An enveloping worm transmission is provided with a unique enveloping worm (56 or 57) and worm gear (55 or 58) with modified enveloping worm thread surfaces. The enveloping worm transmission of the present invention is much smaller than any existing gear transmission and is easy manufactured by using machines for traditional gear cutting.
