Abstract
Mechanism for use in high speed winding machines used for developing coil groups each comprising one or more coils each having one or more turns of winding material. The apparatus may be advantageously utilized in the manufacture of wound inductive devices, e.g., dynamoelectric machines such as motors. Mechanism prevents rotation of a coil form while a flyer rotates and generates winding turns about the coil form. Mechanism may be a migrating linkage having a carriage which supports a wobble face gear having teeth on opposite faces thereof. 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. As a carriage rotates with the flyer, 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. In preferred forms, the mechanism includes a first meshing surface carried by the machine frame; a second meshing surface fastened to or forming a part of a winding form mechanism; and a locking structure supported to accomplish a meshing engagement with the first and second meshing surfaces. The locking structure may be a deformable spline that meshes with the first and second gear surfaces. In another form, the above mentioned carriage may rotate about a first given axis and may support at least one pair of gear surfaces for rotation about a second axis of rotation generally parallel to the first given axis. For example, a pair of gears locked or keyed on a common shaft parallel to but removed from the flyer axis of rotation may be used. The at least one pair of gears would be supported by and rotate with the flyer structure. The gears of such pair would then mesh, respectively, with a gear structure fastened to the machine frame, and with a gear interconnected with a coil form or coil form support. In one of the other forms, strain wave gearing means may be used so as to provide an exit path, preferably generally radially extending for wire that is fed generally axially to mechanisms embodying the invention.
