Kauv bevel iav muab faib ua ob hom, ib qho yog kauvbevel iav, uas nws loj qag thiab me qag sib tshuam; lwm yam yog ib tug hypoid kauv bevel iav, nrog ib tug tej yam offset nrug ntawm lub loj qag thiab lub me qag. Kauv bevel iav yog dav siv nyob rau hauv txhua yam kis tau tus mob teb xws li tsheb, aviation, thiab mining vim lawv zoo xws li loj overlap coefficient, muaj zog nqa peev xwm, loj kis tau tus mob piv, du kis, thiab tsis muaj suab nrov. Nws cov yam ntxwv yog:

1. Ncaj bevel iav: Cov kab hniav yog ib txoj kab ncaj nraim, sib tshuam ntawm apex ntawm lub khob hliav qab, shrinking cov hniav.

2. Helical bevel iav: Cov kab hniav yog ib txoj kab ncaj nraim thiab tangent mus rau ib qho taw tes, shrinking cov hniav.

3. Kauv bevel iav: retractable iav (tseem haum rau cov iav sib npaug qhov siab).

4. Cycloid kauv bevel iav: contour hniav.

5. Zero degree kauv bevel iav: Ob chav txo cov hniav, βm = 0, siv los hloov cov iav bevel ncaj, nrog kev ruaj ntseg zoo dua, tab sis tsis zoo li cov iav bevel.

6. Cycloid hniav xoom-degree bevel iav: Contour hniav, βm = 0, siv los hloov cov iav bevel ncaj, nrog kev ruaj ntseg zoo dua, tab sis tsis zoo li cov iav bevel.

7. Cov hniav qhov siab hom ntawm kauv bevel iav feem ntau muab faib ua cov hniav txo thiab sib npaug qhov siab cov hniav. Cov hniav uas txo qis muaj xws li tsis sib npaug lub taub hau tshem tawm txo cov hniav, sib npaug lub taub hau tshem tawm cov hniav thiab ob chav txo cov hniav.

8. Contour cov hniav: cov hniav ntawm qhov kawg loj thiab qhov kawg me me yog tib qhov siab, feem ntau yog siv rau oscillating bevel gears.

9. Tsis yog isotopic qhov chaw shrinking cov hniav: lub apexes ntawm lub sub-cone, lub sab saum toj cone thiab lub hauv paus lub khob hliav qab yog coincident.
