Nta ntawm av bevel iav hniav thiab lapped bevel iav hniav

Nta ntawm lapped bevel iav hniav

Vim lub sij hawm luv luv, lapped gearings nyob rau hauv loj ntau lawm feem ntau tsim nyob rau hauv ib tug tas mus li txheej txheem (lub ntsej muag hobbing). Cov gearings no yog tus yam ntxwv ntawm tus hniav qhov tob ntawm tus ntiv taw mus rau pob taws thiab ib qho epicycloid-shaped lengthwise hniav nkhaus. Qhov no ua rau txo qis qhov dav ntawm pob taws mus rau ntiv taw.

Thaumbevel iav lapping, tus pinion dhau qhov kev hloov pauv ntau dua li cov iav, txij li lub pinion tau ntsib ntau dua meshing ib tus hniav vim yog cov hniav me me. Kev tshem tawm cov khoom thaum lub sij hawm lapping ua rau txo qis ntawm qhov ntev thiab qhov profile crowning - feem ntau ntawm lub pinion - thiab txo qhov cuam tshuam ntawm kev sib hloov yuam kev. Yog li ntawd, lapped gearings muaj ib tug smoother hniav mesh. Qhov zaus spectrum ntawm ib qho kev xeem flank yog tus cwj pwm los ntawm kev sib piv qis amplitudes nyob rau hauv kev sib haum xeeb ntawm cov hniav mesh zaus, nrog rau cov amplitudes kuj siab nyob rau hauv lub sidebands (suab nrov).

Indexing yuam kev nyob rau hauv lapping tsuas yog txo me ntsis, thiab lub roughness ntawm cov hniav flanks yog ntau dua li ntawm av gearings. Ib tug yam ntxwv ntawm lapped gearings yog hais tias txhua tus hniav muaj ib tug sib txawv geometry, vim hais tias tus neeg hardening distortions ntawm txhua tus hniav.

Hauv kev lag luam automotive,av bevel iavyog tsim los ua duplex gearings. Qhov dav qhov chaw tas mus li thiab qhov tob zuj zus ntawm cov ntiv taw mus rau pob taws yog cov yam ntxwv ntawm qhov kev sib tw no. Cov hniav hauv paus vojvoog yog tas li ntawm tus ntiv taw mus rau pob taws thiab tuaj yeem ua kom tiav vim qhov dav hauv qab av tas li. Ua ke nrog duplex taper, qhov no ua rau muaj kev sib piv ntau dua cov hniav hauv paus muaj peev xwm. Qhov tshwj xeeb txheeb xyuas qhov sib haum xeeb hauv cov hniav mesh zaus, nrog rau qhov tsis tshua pom pom, yog cov cwj pwm tseem ceeb. Rau iav txiav nyob rau hauv tib txoj kev indexing (lub ntsej muag milling), Twin Blades muaj. Qhov tshwm sim muaj pes tsawg leeg ntawm active cut-ting edges tsub kom cov productivity ntawm txoj kev mus rau ib tug tsis tshua muaj siab theem, com-parable rau uas tsis tu ncua txiav bevel zog. Geometrically, bevel iav sib tsoo yog ib qho kev piav qhia raws nraim, uas tso cai rau tus kws tsim qauv tsim kom meej meej qhov kawg geometry. Txhawm rau tsim qhov Yooj Yim Tawm, geo-metric thiab kinematic qib ntawm kev ywj pheej muaj los ua kom zoo rau kev ua haujlwm ntawm tus cwj pwm thiab lub peev xwm thauj khoom ntawm lub gearing. Cov ntaub ntawv tsim tawm hauv txoj kev no yog lub hauv paus rau kev siv qhov zoo kaw lub voj, uas nyob rau hauv lem yog qhov yuav tsum tau ua ua ntej rau qhov tseeb nominal geometry.

Lub geometric precision ntawm av gearings ua rau muaj qhov sib txawv me me ntawm cov hniav geometry ntawm tus neeg toot flanks. Lub indexing zoo ntawm gearing tuaj yeem txhim kho tau zoo los ntawm bevel iav sib tsoo.
