A gear used in automatic machines and feed devices, etc., is used to repeatedly rotate a driven shaft and then stop it for a certain period of time. The simplest type is one in which only some of the teeth of the gear on the driving shaft (driving gear) are provided, and rotation is transmitted only while it is meshed with the gear on the driven shaft (driven gear). However, because this type of device starts and stops suddenly, a pin device is generally used to reduce the impulse. Geneva gears are a typical example. Note that this type of gear device is usually used in conjunction with a locking device to ensure that the driven shaft is stopped.

自動機械や送り装置などに利用される歯車で,従動軸の回転をある期間のみ繰返して静止させる場合に用いる。最も簡単なものは,駆動軸側の歯車 (駆動歯車) の歯を一部だけ設け,従動軸の歯車 (従動歯車) と噛み合っている期間だけ回転を伝達する形式である。しかしこの装置では,起動,停止が急激に行われるため,一般にはピン装置を用いて衝動を緩和する。ゼネバ歯車はその代表例である。なお,この種の歯車装置では,従動軸を確実に静止させるために,通常ロック装置を併用する。
