I praksis deler 3-4 tandpar belastningen samtidigt p\u00e5 et hvilket som helst tidspunkt \u2013 hvilket reducerer den maksimale tandb\u00f8jningssp\u00e6nding med cirka 40% sammenlignet med et cylindrisk tandhjul med samme modul og diameter. Derfor har designere af industrielle gearkasser standardiseret 30\u00b0 til generelle tunge industrielle drev: det giver den st\u00f8rste st\u00f8j- og belastningskapacitetsfordel, der kan opn\u00e5s med standardproduktionsfr\u00e6seudstyr og standard tandprofilgeometri.<\/p>\n<h3 style=\"font-size: clamp(15px,2.5vw+9px,19px); color: #2c3e50; border-left: 4px solid #1a5276; padding-left: 10px; margin-top: 22px; margin-bottom: 8px;\">Dobbelt spiralformet annullering ved 30\u00b0<\/h3>\n<p style=\"font-size: clamp(14px,2vw+10px,17px); color: #2c3e50; line-height: 1.85; margin-bottom: 14px; word-break: break-word;\">Ved \u03b2 = 30\u00b0 er den aksiale kraft pr. spiralformet halvdel = F_t \u00d7 tan(30\u00b0) = 0,577 \u00d7 F_t. For en industriel kranhejsegearkasse, der overf\u00f8rer 500 kNm, ville dette repr\u00e6sentere en aksial kraft, der n\u00e6rmer sig 200 kN p\u00e5 hver halvdel - en kraft, der ville kr\u00e6ve et stort og dyrt aksiallejearrangement i et enkelt spiralformet design. I den dobbelte spiralformede konfiguration oph\u00e6ver disse lige store og modsatrettede kr\u00e6fter pr\u00e6cist ved gearhuset.

Denne service er is\u00e6r v\u00e6rdifuld for industrielle vedligeholdelseskunder, der udskifter tandhjul i \u00e6ldre gearkasser, hvor den oprindelige producent ikke l\u00e6ngere leverer delen. Korea Ever-Power har erfaring med reverse engineering af krantaljer, pumpereduktionsgear og marinegearkomponenter fra pr\u00f8ver leveret i b\u00e5de Korea og Syd\u00f8stasien.<\/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 profilmodifikationer er tilg\u00e6ngelige for industrielle dobbeltspiralformede gear?<\/strong><\/p>\n<p style=\"font-size: clamp(14px,2vw+10px,17px); color: #2c3e50; line-height: 1.8; margin: 0;\">Standardprofilmodifikationer, der er tilg\u00e6ngelige p\u00e5 industrielle dobbeltspiralformede tandhjul, omfatter: spidsaflastning (line\u00e6r eller parabolsk, for at reducere belastningen ved tandindgang\/udgang og minimere dynamisk p\u00e5virkning), blykroning (for at kompensere for tandhjulsudb\u00f8jning under belastning og sikre j\u00e6vn kontaktfordeling i tandfladen), endeaflastning (for at forhindre sp\u00e6ndingskoncentration i enderne af tandfladen p\u00e5 grund af forkert justering eller termisk udb\u00f8jning) og profilforskydning (for at justere centerafstanden og optimere tandstyrkebalancen mellem medbringer og drevet tandhjul).
