ゼネバ歯車についての研究 : 理論解析に基づくゼネバ歯車の試作と実験

The Geneva Stop is one of the intermittent revolving mechanisms. This mechanism has been used for many years as a means of providing intermittent motion. The geneva stop is a mechanism which revolves by gearing the driver formed with the locking disk and the driving pin into the follower with n pieces of radial groove. The mechanism is normally locked during dwell times by a disk on the driver. The locking disk of the driver has been formed with a circular curve. On account of this any residual torque on the follower, just before unlocking or just after locking, can produce chatter, scratch, excessive wear, or even a complete block of the mechanism. This report aims at the research of the notch of the locking disk which is able to lock even if the follower is given a load and to avoid the reverses and the damages. An excellent lock can be realized when the notch is formed with the locus of the follower\u27s addendum corresponding to that of the driver. From this point of riew we can analyze the profile of the locking disk and design the Geneva Stop in order to analyze it experimentally.The Geneva Stop is one of the intermittent revolving mechanisms.
