Dab tsi yog cov yam ntxwv thev naus laus zis ntawm kauv bevel iav hauv precision qhov chaw machining
Nyob rau hauv precision qhov chaw ua, cov yam ntxwv yam ntxwv ntawm kauv hniav yog tib yam li cov ncaj bevel iav. Tus qauv qauv ntawm kauv bevel iav hais txog qhov loj kawg module, thiab kev suav ntawm nominal loj yog qhov pib zoo ib yam. Qhov txawv yog hais tias cov iav hniav profile ntawm yav dhau los yog ncaj, nws lub suab bevel iav kab (txoj kab kev sib tshuam ntawm tus hniav nto thiab lub suab bevel iav kab) yog ncaj, thiab iav hniav profile ntawm tom kawg yog nkhaus, nws lub suab. bevel iav kab yog arc, thiab cov hniav nto yog convex ntawm ib sab ntawm cov hniav ntev kev taw qhia, Lwm sab yog concave.
Tsis tas li ntawd, lub siab lub kaum sab xis ntawm kauv bevel iav yog teev nyob rau hauv cov kev taw qhia ntawm iav hniav. Cov kev taw qhia kev sib hloov thiab lub kaum sab xis ntawm kauv bevel iav yog raws li hauv qab no: thaum tig mus rau sab saum toj ntawm cov iav thiab saib raws tus axis, yog tias qhov me me kawg ntawm cov iav hniav txav counterclockwise raws tus hniav kab mus rau qhov loj kawg, nws yog hu ua sab laug tes; Yog hais tias nws yog clockwise, nws yog hu ua sab tes iav.
Nyob rau hauv precision qhov chaw ua, lub kaum sab xis ntawm lub tangent kab ntawm ib tug taw tes rau lub suab bevel iav kab thiab lub suab bevel generatrix dhau los ntawm lub point yog hu ua lub helix lub kaum sab xis. Lub helix lub kaum sab xis ntawm txhua qhov taw tes ntawm tus hniav duab plaub ntawm cov kauv bevel iav tsis sib npaug, thiab lub helix lub kaum sab xis ntawm qhov nruab nrab ntawm tus hniav nto yog tus qauv helix lub kaum sab xis ntawm cov kauv bevel iav.
