Abstract

Provided is a jig for stator twisting, with which it is possible to easily suppress radial-direction deformation of a projecting portion of a segment coil that projects from a stator core during twisting. A jig 9A for twisting a stator 1, in which projecting portions 7A that include coil ends 7a of a segment coil 7 held by a stator core 3 are bent in a circumferential direction by twisting, comprises: a twisting member 13 having a grasping portion 17 that grasps and displaces the coil ends 7a in an axial direction and a circumferential direction relative to the stator core 3 so as to bend the projecting portions 7A; and a restraint wall 31 which is supported so as to be movable in an axial direction on a radially outer side with respect to the twisting member 13 and which restrains the projecting portions 7A on the radially outer side during bending in the state of projecting in an axial direction with respect to the grasping portion 17.

Abstract

The present invention provides a method for producing a rotor which can suppress the occurrence of a defect such as damage on an inner periphery of an annular member when the annular member is attached to an outer periphery of a rotor core. Provided is a method for producing a rotor 1 in which an annular member 5 is attached to the outer periphery of a rotor core 3 obtained by layering a plurality of plate-like core pieces 9, wherein the rotor core 3, the outer periphery of which is fitted to the annular member 5, is obtained by: disposing, in the annular member 5, the plurality of core pieces 9 in a curved state in which the plurality of core pieces 9 are curved to have a smaller outer diameter; and pressing the plurality of core pieces 9 in the curved state through openings 5a on both sides of the annular member 5 so that the plurality of core pieces 9 each have a flat plate shape.

Abstract

Provided are a method and a device for producing a lamination core, which make it possible to predict occurrence of weld cracks and further facilitate prevention of the weld cracks. The method is for producing a lamination core 1 in which a plurality of core pieces 7 are laminated, and involves welding by applying pressure to the lamination core 1 in the lamination direction, and setting the cumulation of the compression amount of the lamination core 1 by application of the pressure, the contraction amount of the lamination core 1 in the lamination direction at a welded portion, and the spring back amount of the lamination core 1 by release of the pressure, to be within the compression limitation of the lamination core 1.

Abstract

The present invention comprises a first cylindrical member which extends in the longitudinal direction, a second cylindrical member which extends in the longitudinal direction, and an outer cylinder which is externally mounted to the first cylindrical member and the second cylindrical member so as to be rotatable around an axis extending in the longitudinal direction and which extends in the longitudinal direction. The first cylindrical member and the second cylindrical member are provided in a state in which relative movement in the longitudinal direction is possible and relative rotation around the axis is restricted. The outer cylinder is provided to one cylindrical member among the first cylindrical member and the second cylindrical member in a state in which movement in the longitudinal direction is restricted. A first guiding part is formed on the inner circumferential surface of the outer cylinder and on the outer circumferential surface of the other cylindrical member of the first cylindrical member and the second cylindrical member, said first guiding part allowing the other cylindrical member to move longitudinally relative to the one cylindrical member such that the distance between a fastened body and the front end of a supporting tube of a guide wire changes with the relative rotation of the outer cylinder and the other cylindrical member around the axis.
