Abstract
A new type of worm/wormgear transmission with number of wormgear teeth 11 and less described. The worm gear is a split-worm gear. The ratio of worm gear teeth to worm thread less than 11. A unique transmission utilizes a self-locking worm and worm gear combination. The worm (3) is journaled in a rotor (8) such that upon rotation of the worm about an axis of the worm gear (1), the rotor is also rotated. The worm is preferably driven by an auxiliary motor (3) about its own axis under certain conditions. An input to the worm gear (1) is transmitted without relative movement to the thread of the worm to cause the thread and hence the rotor to rotate about an axis of the worm gear. The auxiliary motor preferably rotates the worm thread relative to the worm gear teeth under certain conditions when it is not desired to transmit rotation. A system for transmitting an oscillating input (4) to a single directional output (9) incorporates some of the worm and worm gear combinations.
