ELECTROMAGNETIC ROLLER Russian patent published in 1997 - IPC

FIELD: mechanical engineering; conveyor equipment; transportation of metal sheets. SUBSTANCE: electromagnetic roller has pole disks secured on shaft and provided with noise absorbing dampers installed in grooves, thin walled cylinders with field coils placed inside, electric insulating compound fitted in clearance between thin walled cylinders and field coils and brackets for fastening thin walled cylinders. Noise absorbing dampers are made in form of layers of resilient material strips wound on pole disks in direction coinciding with direction of rotation of electromagnetic roller. Field coils are impregnated with insulating material under vacuum and are made solid with electric insulating material placed in clearance between thin walled cylinders and field coils. Thin walled cylinders are connected with brackets by resilient joints made in form of grooves on ends of carrying branch pipes and holes in cheeks rigidly secured to brackets. Grooves on ends of carrying branch pipes are made of depth smaller than or equal to value of cheek deflection within the limits of their resilient deformation. Slots for arrangement of projections on cheeks are made in grooves. EFFECT: enlarged operating capabilities. 2 cl, 5 dwg
