英语词汇“cog and round”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

a. One of a series of teeth or similar projections on the circumference of a wheel, or the side of a bar, etc., which, by engaging with corresponding projections on another wheel, etc., transmit or receive motion.

Cogs are either separate wooden pieces attached by mortices and the like, or are cut out of the substance of the wheel, or cast in one with it. The name was probably first given to the wooden pins inserted sideways into the rim of a wheel, which caught the rungs or trundles of a lantern-wheel; hence cog and round, a mechanical arrangement of this type. hunting cog: in cogged wheels which have a certain proportion to each other, an extra cog given to the larger, by which there is secured a continuous change of cogs engaging with each other and consequently equal wear.
