Peamine erinevus Ameerika topeltsammuga ketisarjast: Aasia topeltsammuga ketti toodetakse kahe rullit\u00fc\u00fcbiga \u2013 SB (standardne ava \/ standardrullik)<\/strong> kus igal l\u00fclil on standardse JIS-l\u00e4bim\u00f5\u00f5duga rull ja RB (rullava \/ suur rull)<\/strong> kus igal l\u00fclil on suurem kanderull, mis on freesitud suurema l\u00e4bim\u00f5\u00f5duga, et parandada koormuse jaotumist ketijuhikule ja ketirattale. SB ja RB ketid EI OLE omavahel vahetatavad \u2013 hammaste istumisk\u00f5ver ja ketiratta hammaste laius erinevad kahe rullit\u00fc\u00fcbi vahel. Enne asendusketiratta tellimist kontrollige alati, millist rullit\u00fc\u00fcpi teie kett kasutab.<\/p>\n

Rumm on saadaval kahes vormis: Kindel rumm<\/strong> \u2014 tavaline avaga rumm, mis on \u00fchest t\u00fckist freesitud; ja Keevitusrumm<\/strong> \u2014 tehaseseade, kus hambar\u00f5ngas keevitatakse eraldi rummule ja mida kasutatakse v\u00e4ga suure l\u00e4bim\u00f5\u00f5duga ketirataste puhul, kus t\u00e4isvaland oleks eba\u00f6konoomne. T\u00e4isrummud on enamiku suuruste puhul standardsed; keevisrumm on ette n\u00e4htud suurema hammaste arvu korral, kui otsa l\u00e4bim\u00f5\u00f5t \u00fcletab \u00f6konoomse valusuuruse.<\/p>\n

Poolhammaste arv RB t\u00fc\u00fcbi jaoks<\/h3>\n

RB double pitch sprockets are listed with half-tooth counts (6\u00bd, 7\u00bd, 8\u00bd) because only alternate teeth engage the large rollers of the RB chain \u2014 the remaining teeth pass through the plain-pin spaces between rollers. A “6\u00bd tooth” RB sprocket engages 6 rollers and 7 plain pins per revolution. This gives smooth motion with fewer engagement impacts than a same-size SB sprocket where all teeth engage rollers.<\/p>\n<\/div>\n

\n

Keevitusjaam suurte l\u00e4bim\u00f5\u00f5tude jaoks<\/h3>\n

Suure hammaste arvuga NK2080 ja NK2100 puhul (Do \u00fcle 150 mm) kasutatakse keevisrummu konstruktsiooni, kus hambar\u00f5ngas l\u00f5igatakse plasma abil terasplaadist ja keevitatakse eraldi t\u00f6\u00f6deldud rummule. See v\u00e4hendab nii materjalij\u00e4\u00e4tmeid kui ka t\u00f6\u00f6tlemisaega v\u00f5rreldes sama suurusega t\u00e4isvalandiga. Keevisrumm on m\u00f5\u00f5tmetelt samav\u00e4\u00e4rne t\u00e4isrummuga ning kasutab sama ava ja kiilusoone spetsifikatsiooni.<\/p>\n<\/div>\n

Konveieri majanduse rakendus<\/h3>\n

Kahekordse sammuga ketirattad ja kett on standardspetsifikatsioon aeglaste Jaapani ja Korea toodetud liistkonveierite, rippkonveierite ja kaubaaluste kogumiss\u00fcsteemide jaoks. NK2040 Z=10 juures pakub 250 mm sammuga ringi l\u00e4bim\u00f5\u00f5tu \u2013 mis vastab standardsele NK40B Z=20 ketirattale \u2013 oluliselt madalama keti hinnaga meetri kohta. Konveieri kiiruste korral alla 0,5 m\/s ja kergete koormate puhul, mille keti kogut\u00f5mbej\u00f5ud on alla 200 kg, on NK2040 kett ja ketirattad k\u00f5ige kulut\u00f5husam ajamilahendus. Sobib...
