Abstract

Segment jarzma wirnika składa się z pakietu blach wirnika maszyny elektrycznej, wzbudzanej magnesami trwałymi, umieszczonymi wewnątrz jarzma. Segmenty (6) osadzone są na wale (8), na klinie bądź wypustach, i są ściśnięte śrubami (3) bądź nitami. Blachy (1) w części jarzmowej mają n otworów (1.2, 1.3) pod śruby (3) bądź nity. W blachach (1) otwory 1.3 mają średnicę d2 większą od średnicy d1 otworów 1.2. Średnica d2 umożliwia zagłębienie główek śrub (3), ściskających segmenty (6) w otworach (1.3) po obróceniu każdego kolejnego segmentu o 180° względem poprzednika w procesie nakładania segmentów (6) na wał (8) maszyny.The rotor yoke segment consists of a package of electric machine rotor sheets excited by permanent magnets placed inside the yoke. The segments (6) are mounted on the shaft (8), on a key or splines, and are pressed together with screws (3) or rivets. The sheets (1) in the yoke part have n holes (1.2, 1.3) for screws (3) or rivets. In sheets (1), holes 1.3 have a diameter d2 larger than the diameter d1 of holes 1.2. The diameter d2 allows the heads of the screws (3) compressing the segments (6) to be recessed into the holes (1.3) after rotating each subsequent segment by 180° relative to its predecessor in the process of placing the segments (6) on the shaft (8) of the machine.
