Abstract

This magnet residual 10 requires no extra machining or a bonding operation to magnet coil 12 or armature 14. The residual is free of any adhesive backed materials which may work out after repeated pounding and closing of the armature to cause sticking; and residual 10 is low-cost and easily replaced on magnets in the field.

Slip On Magnet Residual

This magnet residual 10 requires no extra machining or a bonding operation to magnet coil 12 or armature 14. The residual is free of any adhesive backed materials which may work out after repeated pounding and closing of the armature to cause sticking; and residual 10 is low-cost and easily replaced on magnets in the field.

The residual 10 consists of a urethane rubber ring which is extruded in long tubular lengths and then cut to the desired length so that it may be slipped on and fit over a portion of armature 14. Armature 14 completes a magnetic circuit including coil 12 and is moved toward coil 12 against the action of a spring 16 by energizing coil 12. Residual 10 is held onto armature 14 by means of its own resilience, similar to a rubber band on a roll of paper and separates the armature from the adjacent end of the coil.
