ELECTROMAGNETIC ROLLER Russian patent published in 2004 - IPC

FIELD: rolling of metals.

SUBSTANCE: invention relates to equipment for transportation and packing of sheets in ferromagnetic steel cross slitting sets. Proposed electromagnetic roller has drive shaft with pole disks on which combination cylindrical noise-suppressing shock absorbers and field coils are mounted. Coils are arranged in housing. Clearances in housing are filled with electric insulating material to form monolith. Noise-suppressing shock absorbers are made up of outer solid ring made of ferromagnetic wear-resistant material and inner ring made of elastic material. Noise-suppressing gaskets made in form of elastic material rings are fitted in groove of pole disks from both sides of outer solid and inner rings. Thickness of outer ring of noise-suppressing shock absorber is not less than twice as great as thickness of transported material. Wear resistance of roller is increased, service life of noise-suppressing rings is increased and friction of roller rolling along transported sheet is decreased.

EFFECT: improved reliability of roller.
