gearing (gering)

[Verbal n. of gear, v.] 1. Gear; dre ; harne .-2. In mach., the parts collectively by which motion communicated to one part of a machine is transmitted to another; specifically, a train of toothed wheels for transmitting motion. There are two chief sorts of toothed gearing, namely, spur - gearing and beveled gearing. In the former the teeth are arranged round either the concave or the convex surface of a cylindrical wheel in the direction of radii from the center of the wheel, and are of equal depth throughout. In beveled gearing the teeth are placed upon the exterior periphery of a conical wheel in a direction converging to the apex of the cone, and the depth of the tooth gradually diminishes from the base. See bevel, and cut under bevel -gear. - Angular gearing. See angular. - Beveled gearing. See def. 2.-Conical gearing, a gearing arrangement in which the motion is transmitted by a pair of cogged cones through interposed pinions. Elliptical gearing, geared wheels of an elliptical shape, used to obtain a rotary motion of variable speed: also called elliptical wheel. Hooked gearing, a form of gearing having the J. Baillie , Woo'd and Married and A'. teeth set somewhat obliquely acro the face of the wheel, 5. The diameter of an imaginary wheel whose circumference is equal to the distance traversed by a safety-bicycle during a single revolution of the pedals: as, a 72-inch gear. [Colloq.] 6t. A matter; an affair; affairs collectively. so that the contact of each tooth begins at its forward end and ceases at the opposite end. The spiral has such a pitch that one pair of teeth remains in contact until the next pair comes together. - Hooke's gearing [named for Robert Hooke, English mathematician and philosopher (1635-1703)], a kind of gearing for wheels, in which the teeth are cut in a helicoidal form. - Multiplying gearing, in mach., a combination of cog-wheels in common use for imparting motion from wheels of larger to those of smaller diameter, so as to increase the rate of revolution. Spenser, F. Q., VI. iii. 6. Quick-return gearing, in some forms of planing-ma To cheare his guests whom he had stayd that night, And make their welcome to them well appeare; That to Sir Calidore was easie geare. But I will remedy this gear ere long, Or sell my title for a glorious grave. Shak., 2 Hen. VI., iii. 1. I trust you all, my dearly beloved, will consider this gear with yourselves, and in the cro see God's mercy. J. Bradford, Letters (Parker Soc., 1853), II. 37. chines, a system of mechanism fitted to the feed for causing the bed to return at increased speed after each cutting stroke. The stroke is slow, and the return to the first position is accelerated in order to save time. - Spiral gearing, two cylinders set parallel, and having spiral ribs and grooves that mesh or gear together.- Stepped gearing, a form of gearing in which each tooth or cog on the face of a wheel is replaced by a series of smaller teeth 7t. Ordinary manner; behavior; custom; pracarranged in steps. The device is allied to the stepped tice. Into a studie he fel al sodeynly, As don thes loveres in here queynte geres , Now in the croppe, now doun in the breres. Chaucer, Knight's Tale, 1. 673. Bairns' part of gear, in Scots law, same as legitim. Differential gear. those parts of a machine which are most nearly concerned in effecting motion, as, in a locomotive, the parts from the cylinder to the wheels inclusive. Full backward gear, with the valve-gearing adjusted to produce backward motion of the steam-engine. - Full forward gear, with the valve-gearing adjusted to produce forward motion of the engine.-Guids and gear, all one's property. [Scotch.] - Inside gear, the English arrangement of pitmans and See differential . - Driving-gear, cranks inside the frame of a locomotive, as distinguished the engines to the wrists on the exterior of the driving wheels by pitmans. - Internal gear, a wheel having its cogs on the internal perimeter. Out of gear, not in working or running order; not in a condition for use or operation. from the American method of attaching the cro -heads of Its own [the North's] theory and practice of liberty had got sadly out of gear , and must be corrected. Emerson, Addre , Soldiers' Monument, Concord. Then sware Lord Thomas Howard: "'Fore God I am no coward! of the ma of rocks a geanticlinal, and the production of a long, narrow, and lofty ridge. Thirdly, the carving out of this shapele ma into peaks and valleys. A. H. Green, Phys. Geol.
