Siktmoment och hastighet<\/h3>\n

Blanda inte nominellt vridmoment med en gissad \u00f6verbelastningsfaktor.<\/h2>\n

Standard NM-intervallet anv\u00e4nder nominellt vridmoment. Vissa andra NM-referenser p\u00e5 marknaden publicerar andra v\u00e4rden, men dessa v\u00e4rden \u00e4r inte utbytbara med detta intervall. Om din applikation har uttalade starter eller st\u00f6tar, skicka in belastningen f\u00f6r granskning ist\u00e4llet f\u00f6r att till\u00e4mpa en obekr\u00e4ftad \u00f6verbelastningsfaktor.<\/p>\n

Borrkapaciteten kan \u00e4ndra storleken efter att vridmomentet redan \u00e4r uppfyllt.<\/h2>\n

En liten modell kan b\u00e4ra driftsmomentet men \u00e4nd\u00e5 vara oanv\u00e4ndbar eftersom en axel \u00f6verskrider sitt angivna maximala h\u00e5l. Flytta upp\u00e5t endast efter att ha kontrollerat att den st\u00f6rre modellen ocks\u00e5 passar den tillg\u00e4ngliga ytterdiametern och det axiella utrymmet. F\u00f6r NM194 och NM214, kom ih\u00e5g att den nominella hastighetsgr\u00e4nsen sjunker till 1500 rpm.<\/p>\n

Vad som ska anges i offertf\u00f6rfr\u00e5gan<\/h2>\n

Ange NM-modell om vald, driftshastighet, konstruktionsmoment eller motoreffekt, drivaxeldiametrar f\u00f6r drivning och drivning, b\u00e5de kilsp\u00e5r, antal och destination. L\u00e4gg till starter per timme, reversering, st\u00f6td\u00e4mpning, milj\u00f6 och eventuella materialf\u00f6rfr\u00e5gningar n\u00e4r de \u00e4r relevanta. Om applikationen \u00e4r en ers\u00e4ttning, inkludera den gamla modellen och uppm\u00e4tta dimensioner, men behandla dessa som identifieringshj\u00e4lpmedel snarare \u00e4n ers\u00e4ttningar f\u00f6r axeldata.<\/p>\n
