Gears yog ib qho ntawm cov khoom siv tseem ceeb siv los xa lub zog thiab txoj haujlwm. Designers cia siab tias lawv tuaj yeem ua tau raws li ntau yam kev xav tau:
Lub zog muaj peev xwm tshaj plaws
Yam tsawg kawg nkaus
Tsawg suab nrov (nqi ua haujlwm)
Qhov tseeb rotation / txoj hauj lwm
Yuav kom ua tau raws li qib sib txawv ntawm cov kev xav tau no, yuav tsum muaj qib tsim nyog ntawm cov iav raug. Qhov no suav nrog ntau yam iav iav.
Qhov tseeb ntawm Spur Gears thiab Helical Gears
Qhov tseeb ntawmspur zogthiabhelical iavtau piav qhia raws li tus qauv GB/T10059.1-201. Cov txheej txheem no txhais thiab tso cai rau kev sib txawv ntawm cov iav hniav sib txuas. (Qhov kev qhia tshwj xeeb piav qhia txog 13 qib qhov tseeb ntawm 0 txog 12, qhov twg 0 yog qib siab tshaj plaws thiab 12 yog qib qis tshaj).
(1) Adjacent Pitch Deviation (fpt)
Qhov sib txawv ntawm qhov ntsuas pitch tus nqi thiab qhov theoretical ncig pitch tus nqi ntawm cov hniav uas nyob ib sab.
Qhov sib txawv ntawm qhov sib txawv (Fp)
Qhov sib txawv ntawm qhov theoretical sum ntawm pitch qhov tseem ceeb nyob rau hauv ib qho kev sib tw iav thiab qhov ntsuas qhov tseeb ntawm cov txiaj ntsig hauv qhov sib txawv.
Helical Total Deviation (Fβ)
Lub helical tag nrho kev sib txawv (Fβ) sawv cev qhov kev ncua deb raws li qhia hauv daim duab. Qhov tseeb helical kab yog nyob nruab nrab ntawm lub sab sauv thiab sab helical daim duab. Tag nrho helical sib txawv tuaj yeem ua rau cov hniav tsis zoo, tshwj xeeb tshaj yog nyob rau hauv cov chaw sib cuag. Shaping ntawm cov hniav yas thiab qhov kawg tuaj yeem txo qhov kev sib txawv no.
Radial Composite Deviation (Fi")
Tag nrho cov radial composite sib txawv sawv cev rau qhov kev hloov ntawm qhov chaw nyob deb thaum lub iav rotates ib tug tag nrho tig thaum meshing ze nrog tus tswv iav.
Gear Radial Runout yuam kev (Fr)
Runout yuam kev yog feem ntau ntsuas los ntawm kev ntxig ib tus pin lossis pob rau hauv txhua qhov hniav nyob ib ncig ntawm lub voj voog ntawm lub iav thiab sau qhov sib txawv siab tshaj plaws. Runout tuaj yeem ua rau muaj ntau yam teeb meem, ib qho ntawm cov suab nrov. Lub hauv paus ua rau ntawm qhov yuam kev no feem ntau tsis txaus precision thiab rigidity ntawm lub tshuab cuab yeej fixtures thiab cov cuab yeej txiav.
