Den vigtigste strukturelle forskel er en central aflastningsrille: dobbeltspiralformede tandhjul har en rille mellem de to s\u00e6t t\u00e6nder, hvilket giver v\u00e6rkt\u00f8jsfrigang under fremstillingen. Sildebensformede tandhjul har ingen rille - venstre og h\u00f8jre t\u00e6nder m\u00f8des i midten - hvilket giver en lidt h\u00f8jere udnyttelse af fladebredden, men kr\u00e6ver mere specialiseret produktionsudstyr.<\/p>\n<\/div>\n<hr style=\"border: none; border-top: 1px solid #e0e0e0; margin: 16px 0;\" \/>\n<div style=\"margin-bottom: 8px;\">\n<p><strong style=\"font-size: clamp(14px,2vw+10px,17px); color: #1a5276; display: block; margin-bottom: 6px;\">Hvorfor producerer dobbeltspiralformede gear nul aksial trykkraft?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw+10px,17px); color: #2c3e50; line-height: 1.8; margin: 0;\">Hver helixsektion genererer en aksial kraftkomponent. I dobbelthelixdesignet har de to sektioner identiske helixvinkler, men modsatrettede. Kr\u00e6fterne er lige store og modsatrettede i retning, s\u00e5 de oph\u00e6ver hinanden i gearhuset.

Vinkler op til 45\u00b0 anvendes i h\u00f8jhastighedsturbinegear, hvor maksimalt kontaktforhold er p\u00e5kr\u00e6vet. Under 20\u00b0 mindskes fordelen i forhold til enkeltspiralformede gear; over 45\u00b0 bliver fremstillingstolerancerne meget kr\u00e6vende, og tandglidefriktionen \u00f8ges.<\/p>\n<\/div>\n<hr style=\"border: none; border-top: 1px solid #e0e0e0; margin: 16px 0;\" \/>\n<div style=\"margin-bottom: 8px;\">\n<p><strong style=\"font-size: clamp(14px,2vw+10px,17px); color: #1a5276; display: block; margin-bottom: 6px;\">Hvilke materialer findes der til dobbeltspiralformede gear?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw+10px,17px); color: #2c3e50; line-height: 1.8; margin: 0;\">Korea Ever-Power leverer dobbeltspiralformede tandhjul i 45# kulstofst\u00e5l (generelt, normaliseret eller afk\u00f8let og anl\u00f8bet til HB 220-280), 40Cr legeret st\u00e5l (induktionsh\u00e6rdet, HRC 48-54 overflade) og 20CrMnTi (karbureret og afk\u00f8let til HRC 58-62).
