摘要:
A tension apparatus for imposing a predetermined tension on a wire-like member which is used for a stator or a alternator. First and second rollers are rotatably supported on a supporting means in such a manner that a space between the first roller and the second roller is smaller than a diameter of the wire-like member. When the wire-like member is passed through a space between a first roller and a second roller, the wire-like member is deformed, and after all, a predetermined tension is imposed on the wire-like member. The tension of the wire-like member can be changed in accordance with the space between the first roller and the second roller.

A winding machine includes flyers 5 rotated around a flyer rotation axis AXf orthogonal to the axis AXs of a rotor 2 constituting a work while at the same time winding wires 6 on core 23 of rotor 2. Rotor 2 is set in the winding machine in such a position that the center position of core 23 in the direction along rotor axis AXs and flyer rotation axis AXf are displaced from each other.

There is provided a method of forming grooves in a resin bobbin (90), and the resin bobbin (90) has a cylindrical portion around which a coil is wound and a plurality of grooves are formed on a surface of the cylindrical portion in the winding direction of the coil. While a forming die (2) for grooving is being pushed onto the surface of the cylindrical portion, the forming die (2) for grooving is vibrated, and the forming die (2) for grooving is separated from the surface of the cylindrical portion after the completion of grooving of the cylindrical portion.

The present invention generally relates to a coil insertion device for inserting a stator coil into a slot defined within a stator core of an electric rotary machine and to an improvement in a mechanism for inserting a stator coil into a slot. The coil insertion device includes a plurality of clamping guides moveable along the inner peripheries of the stator core and the base body and circumferentially arranged in a regularly spaced relationship, a plurality of coil clampers arranged radially inward and in opposition to the clamping guides for clamping a prewound stator coil in an aligned condition with the clamping guides and for shifting upward according to an upward movement of the clamping guide to draw the stator coil into the slots at a given angle of tilt, and a plurality of blades moveable along the inner periphery of the base body, the blades being formed in an essentially identical configuration and having essentially the same arrangement as the clamping guides 52, thereby permitting a stripper extending therethrough to push the stator coil into the slot by an upward movement after an insertion by the coil clampers.
