    • 专利摘要:
    A method of forming a stator assembly for a dynamo electric machine. The stator assembly is of the kind including a laminated member in the form of a helically coiled metal strip, and the method includes driving the metal strip into a former which coils the strip helically. As the strip is coiled helically a set is imparted to the strip so that the convolutions of the coiled strip produced are biased towards one another in an axial direction by their own inherent resilience. Apparatus for performing the method includes a former having a cylindrical concave surface. A driving arrangement drives the metal strip against the cylindrical concave surface of the former so that the strip is deformed into a helical coil. The apparatus includes means for example including a pair of rolls between which the strip passes, and which deflect the strip, so as to impart to the strip a set such that the convolutions of the helically coiled strip produced are biased in an axial direction towards one another.

    专利说明:

    dinene with body 1. Screw 17 serves to set the angular position of the holder 10 and rollers 12 and 13 relative to the body. The axes of the rollers 12 and 13 are located at a distance independently from each other in the irile, which is located on the right plane of the chamber 2, and there is a gap 19 with the rollers. The gap 19 and the angle of inclination of the holder 10 determine the degree of deviation of the tape. 12 and 13 to the plane of the camera. Rollers 12 and 13 only touch the ribbon in a continuous width section. To adjust the gap between the rollers 12 and 13, the roller 12 is mounted on an eccentric element, which can be rotated relative to the holder 10. The roller 12 can be mounted on a movable lever fixed to the possibility of adjusting its position on the body, while the roller 13. is not supported.
    The device works as follows.
    The belt 4 is fed into the chamber 2 by means of a gear (not shown), the tooth of which is engaged with the grooves 5. The gear is driven by an electric motor and rotates in a plane perpendicular to the plane of the belt 4.
    At the entrance of the tape into the chamber 2 through the entrance -. The new opening 3 adjoins the concave side surface of the chamber, deforms and fills the space within the chamber. After making a nearly complete rotation of the tape inside the chamber, it passes along an inclined protrusion 6, which directs it upwards in the plane of the inlet 3 to the outlet (not shown in the drawings), from which the ribbon leaves rolled up in a spiral. Inside the chamber, the tape is deflected by the rollers 12 and 13 and the very base of the chamber. Thus, the coils of the helix, due to their inherent elasticity, are in contact with each other, which eliminates the crimping operation of the magnetowire and increases the productivity.
