METHOD FOR PROTECTIVE PAINTING OF HOLLOW PARTS OF ELECTRIC MACHINES Russian patent published in 2002 - IPC

FIELD: electrical engineering, possibly manufacture of electric machines, mainly hollow parts of induction motors. SUBSTANCE: method comprises steps of suspending at least one hollow part to suspension of conveyer, moving it to painting station, preparing, painting, drying and moving to station for assembling electric machines or to storehouse. Novelty is conveyer suspension in the form of guiding three-dimensional rod framework mounted at least onto one rod and rigidly secured to solid base and having detachable protective cover including at least one open slit whose length is no less than summed length of radius of protective cover and diameter of rod positioned in center relative to lengthwise axis of framework or spaced by distance no less than that from edge of protective cover in zone of inlet mouth of its slit until inner face of rod when the last is positioned outside center of lengthwise axis of framework. Part subjected to painting or drying is placed onto solid base at arranging framework in cavity of part or parts placed by floors. Height of framework or at least of its portion placed in cavity of part or parts is no more than height of painted part or it is no more than summed height of hollow parts fit onto framework and subjected to simultaneous painting. Part or parts are fit onto framework at performing all operations for preparing, painting, drying and transporting. EFFECT: enhanced quality of painting, improved efficiency, lowered labor consumption, economy of painting materials, improved ecological conditions at painting process. 12 cl, 9 dwg
