Abstract: There is provided a composite plain bearing having excellent heat resistance, creep resistance under high surface pressure, low friction, abrasion resistance, and other characteristics while being capable of manufacture with high productivity. A composite plain bearing (1) comprising an ingot metal plate (2) and a resin layer (3) comprises a resin composition in which an aromatic polyether ketone resin or the like is used as a base resin, wherein the resin layer (3) is overlaid by injection molding and integrally provided on the surface on the surface of the ingot metal plate (2) to a thickness of 0.1 to 0.7 mm. The ingot metal plate (2) is chemically surface-treated on a face joined to the resin layer (3).

Abstract: 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.

Abstract: An apparatus for forming a field coil with a low load comprises a rotary table, a reel table to be turned together with the rotary table, six reel bars for guiding and winding a conductor into the coil according to the rotation of the rotary table, and six shaping units disposed alternately with the reel bars. The shaping units are radially movable on the rotary table. A groove-cam-type moving mechanism radially reciprocates, at a rate of one reciprocation per turn of the rotary table, the shaping units on the rotary table with predetermined phase shifts between the movements of the shaping units, thereby pushing the conductor stretched between the reel bars toward the center of the rotary table and shaping the conductor.

Abstract: 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.
