The worm gears are useful where the transmission ratio and the self-locking are needed (for particular gears). In the automotive industry, the worm gears are used in worm-and-roller steering gears, drives of the windshield wipers, wind-down car windows, etc. These gears have various versions, as a helical worm-gear and a globoidal worm-gear. The globoidal worm-gear, with rotary teeth was presented. This is an innovative idea connected with this type of gears. In the gear, the globoidal worm gear was used, and the classical worm wheel was replaced by the wheel with rotary teeth in the shape of the frustum of cone. The frustum of cone shape is needed because of minimization of the slippage between the teeth and the surface of the worm gear. The gear teeth have the helical shape. Rotation of the teeth, having appropriate angle of the conical surface, helps to minimize the slippage. In addition, the teeth are able to displace axially. In use, the teeth are pressed against the worm surface by the push springs. It allows eliminating the backlash and improving the gear operation. This type of gear, compared to classic globoidal gear has much higher efficiency. This facility results from replacing the worm friction on the worm wheel into the journal friction in a rolling bearing, where the rotary tooth is bearded. The capacity of the globoidal worm gear, compared to the classic gear is lower, but the uniformity of the load distribution on all teeth is strong advantage of it. Abovementioned gear can be used where the high transmission ratio is needed and the backlash caused during the gear exploitation is impermissible. For example, it can be used in steering system.
