High torque, electrically-operated friction clutch for textile looms, includes rotary disc armature welded at edges to spring component of same outer diameter

摘要

The spring plate (7) is welded (10) to the armature (6), which is a rotary disc component with a circumferential edge (6a). The spring reaches out radially to this edge, having the same outer diameter. It is at this edge that a laser weld is made. The spring is optionally fastened to the armature with spacers at right angles to flat areas of these components. A spacer is welded to the remaining armature components.
