Gear'ing, n.
n. 1. Harness.
Sense 2. (Mach.) The parts by which motion communicated to one portion of an engine or machine is transmitted to another, considered collectively; as, the valve gearing of a locomotive engine; belt gearing; especially, a train of wheels for transmitting and varying motion in machinery.
Frictional gearing, gearing in which the wheels transmit motion by surface friction, the corresponding surfaces being sometimes grooved to increase the friction. — Frictional beveled gearing, gearing in which the grooves are parallel and of equal depth on the conical faces of the wheels. — Spur gearing, gearing in which the teeth or cogs are ranged round either the concave or convex surface (properly the former) of a cylindrical wheel, in the direction of radii from the center of the wheel. — Toothed beveled gearing, gearing in which the teeth are placed on the exterior periphery of a conical wheel, in a direction converging to the apex of a cone, and the depth of tooth gradually diminishes from the base.
Spur Gearing.
Gearing and its compounds are sometimes spelled with ee instead of ea in the first syllable; as, geering, &c.
