Abstract: For winding a field coil onto a two pole stator core of the type having pole pieces with coil support extensions with outwardly extending coil retaining fingers, two pairs of winding forms are removably supported on carriages manipulated to mount the winding forms on the coil support extensions before winding a stator and to remove the winding forms after winding. During winding, the winding forms are clamped to the coil support extensions by spring-biased latch mechanisms interconnecting the opposite pairs of winding forms. Each latch mechanism includes a rotatable latch member which, in one embodiment, is rotatable about an axis that is generally parallel to the longitudinal axis of the stator being wound or, in another embodiment, is rotatable about an axis generally perpendicular to the longitudinal axis of the stator being wound.

Abstract: Apparatus for winding the stator of an electric motor with two wires simultaneously are provided. The apparatus includes a stator winding needle having two separate wire delivery channels. The leads of the two wire to be wound are passed through the winding needle and are held by start lead holders. When winding is complete, the wires are identified by a lead pulling apparatus which rotates in a predetermined direction to grip an appropriate wire. The lead pulling apparatus draws each of the wires to a termination lead holder. Each wire is gripped and cut by a gripping assembly, which holds the cut leads in a predetermined position to facilitate winding of a subsequent stator.

Abstract: A constant velocity joint of the cross groove type wherein the outer joint member and the inner joint member are provided with a plurality of guide grooves circumferentially inclining with respect to their rotational axes. Each of the guide grooves is divided into a groove center portion having a symmetric shape with respect to the center line of the groove, and a pair of groove end portions having an asymmetric shape with respect to the center line of the groove. The pair of groove end portions of each guide groove have a depth larger than that of the groove center portion thereof so that a grinding wheel is prevented from contacting with the groove end portions during grinding operations on the guide grooves, thereby achieving the grinding operations accurately.

Abstract: A link for use in a link-type rotary coupling. The link has an elastomeric bearing which incorporates a pair of cavities that provide discontinuities for preventing the transfer of tensile stresses in the elastomeric layers when the link is tensioned axially while permitting the elastomeric layers to accept compressive stresses when the link is compressed axially.

Each chamber has a pair of face-to-face longitudinal guideways. The inner joint member has three trunnions which radially extend into the three longitudinal chambers. Each longitudinal guideway is rollingly engaged by a planar roller bearing which is movable therealong. A movable race is disposed between each planar roller bearing and the trunnion extending into its associated chamber. The movable race has a flat surface engaging the planar roller bearing, a concave trunnion seat mating with the spherical surface of the trunnion, and a pair of transverse stop abutments which limit the longitudinal displacement of the planar roller bearing along the guideways relative to the movable race.
