Stator winding shaft with stroke adjustment

摘要

A stator winding apparatus includes devices for adjustment of the pivot of the needle and of the stroke of the needle. The apparatus includes a winding shaft assembly which includes a drive shaft, a second shaft which reciprocates linearly in response to rotation of the drive shaft, and a third shaft in which said second shaft is coaxially received. A crank shaft is coupled by an adjustable coupling to the drive shaft and the second shaft to adjust the stroke of the second shaft. Reciprocation of the second shaft causes the needle to pivot radially inwardly and outwardly.
