Skew-bev′el wheel.
(Machinery.) A form of wheel employed to transmit a uniform velocity ratio between two axes which are neither parallel nor intersecting. The pitch surface of a skew-bevel wheel is a frustum or zone of a hyperboloid of revolution. In one of the figures (B), a pair of large portions of such hyperboloids are shown rotating about axes a b c d. In the other figure are shown a pair of narrow zones of the same figures, such as are employed in practice.
