Abstract

Abstract A high speed winding machine for developing or generating coil groups each comprising one or more coils each having one or more turns of winding material. The turns are developed and placed on coil turn receiving means such as coil injection tooling or a coil transfer mechanism with or without auxiliary coil shaping means. The apparatus may be advantageously utilized in the manufacture of wound inductive devices, e.g., dynamoelectric machines such as motors. An illustrated preferred embodiment includes a frame, a coil form support having auxiliary coil shaping means embodied as a coil form mounted thereon for axial movement relative to the frame, and a flyer rotatable about a central axis for developing wire turns on the coil form. In order to prevent rotation of the coil form, located in the vicinity of the central axis, with the rotating flyer and a rotating wire feed tube, a migrating mechanical linkage is provided between the frame and coil form support to prevent rotation of the coil form with the rotating flyer. The illustrated migrating linkage includes a carriage which supports a wobble face gear and is rotatable relative to the gear. The wobble gear is provided with teeth on opposite faces thereof and the teeth on one face of the wobble gear mesh with the stationary gear teeth on the frame while teeth on the other face of the wobble gear engage the gear on the coil form support. The stationary gear teeth and gear teeth on the coil form support are spaced apart and the wobble gear extends between the spaced gears so that portions of the wobble gear spaced 180* apart engage the stationary gear teeth and gear teeth on the coil form, respectively. The wobble gear carriage is canted relative to the central axis and as it rotates it drives succeeding teeth on the faces of the wobble gear into engagement with succeeding ones of the stationary and coil form support gear teeth. As the carriage rotates with the flyer, the wobble gear executes a rotationless wobble motion synchronized with the flyer. This motion results in a moving shutter, synchronized with the flyer, through which wire is fed to the flyer.
