Device for fixing winding bars on a stator of an electric rotating machine
First Claim
Patent Images
1. Device for fixing groups of winding bars on the generally cylindrical internal surface of the magnetic circuit of the stator of an electric rotating machine having an axis of rotation, these groups of bars extending parallel to said axis with the external face of each group being against said internal surface of the stator, said device comprising:
- straps stretched in a direction transverse to said axis, a middle portion of each of these straps bearing against the internal face of a group of bars, so that the external face of that group is clamped against said internal surface of the stator;
fastening elements fixed to said surface of the stator on each side of each group of bars; and
chocks clamping the two end portions of each strap against the fastening elements and urging these end portions radially towards said stator surface to stretch said straps and urge said group toward said stator surface;
the thickness of these chocks, measured in the circumferential direction, increasing in the direction from said axis to said stator surface.
