Shaft rotation limiter 6

Pinned disks limit shaft turns to (N+1).α/360, where N is the number of idle disks,

α is angle depending on pin diameter and distance between pin center and shaft center.

For this limiter: 7 idle disks allow shaft to rotate 7.1 turns.

There is a friction clutch between the driving pulley and the shaft.

The mechanism can be used for winding springs. The red wire on the left shows how to clamp the wire end for winding springs
