Spline ncej yog muab faib ua ob hom:
1) rectangular spline ncej
2) suav nrog spline ncej.
Lub kaum sab xis spline nyob rau hauv lub spline ncej yog dav siv, thaum lub involute spline ncej yog siv rau loj loads thiab yuav tsum tau high centering raug. thiab kev sib txuas loj dua. Rectangular spline shafts feem ntau yog siv rau hauv dav hlau, tsheb, tsheb laij teb, tshuab cuab yeej tsim, tshuab ua liaj ua teb thiab cov khoom siv sib kis. Vim muaj ntau tus hniav ua haujlwm ntawm lub kaum sab xis spline, nws muaj peev xwm ua tau zoo, nruab nrab zoo thiab kev taw qhia zoo, thiab nws cov hauv paus hniav ntiav tuaj yeem ua rau nws qhov kev ntxhov siab me me. Tsis tas li ntawd, lub zog ntawm cov ncej thiab lub hub ntawm spline ncej yog tsis muaj zog, kev ua tau yooj yim dua, thiab ntau dua precision tuaj yeem tau los ntawm kev sib tsoo.
Involute spline shafts yog siv rau kev sib txuas nrog cov loads siab, siab nruab nrab qhov tseeb, thiab qhov loj me. Nws cov yam ntxwv: tus hniav profile yog involute, thiab muaj radial quab yuam ntawm tus hniav thaum nws yog loaded, uas muaj peev xwm ua si lub luag hauj lwm ntawm tsis siv neeg centering, kom lub zog ntawm txhua tus hniav yog uniform, siab zog thiab lub neej ntev, kev siv tshuab yog tib yam li cov iav, thiab nws yog ib qho yooj yim kom tau txais high precision thiab interchangeability
