Dab tsi yog precision zog?

1, lub tswvyim ntawmPrecision iavteem nqi

Precision iav qib yog hais txog qhov tseeb ntawm cov txiaj ntsig ntawm cov tshuaj tiv thaiv hniav ua yuam kev, eccentricity, thiab lwm yam. Lub zog ntawm cov qhab nia sib txawv muaj qhov sib txawv sib txawv thiab thauj khoom muaj peev xwm, haum rau cov teb sib txawv thiab cov kev xav tau.

2, Txheem rau precision iav qib

Lub ntsiab precision iav cov qauv siv tam sim no yog AGMA (Asmeskas haiv neeg ntawm cov qauv neeg kho tshuab), ISO, tus qauv JIS (Japanese muaj kev pab muaj neeg). Hauv qab no yog cov qib kawm tshwj xeeb rau peb cov qauv no.

① AgrA theem

Qib AGMA yog ib qho ntawm feem ntau siv cov qauv qeb rau 11 nkoj hluav taws xob, thiab lwm yam; Txawm li cas los xij, AGMA 5 lub zog muaj zog muaj tsawg tus nqi qis dua thiab feem ntau yog siv rau cov ntawv thov uas tsis tas yuav muaj qhov ntsuas siab, xws li dav dav tshuab kis las.

② Qib ISO

ISO grade is a precision gear grade standard developed by the International Organization for Standardization, which divides precision gear grades into nine levels: ISO 4, ISO 5, ISO 6, ISO 7, ISO 8, ISO 9, ISO 10, ISO 11, ISO 12, etc. Among them, ISO 4 grade gears have the highest precision and are mostly used in high-precision machine tools and aerospace instruments; Txawm li cas los xij, ISO 12 qib zog tsis muaj qhov tseeb qis thiab feem ntau siv rau cov ntawv thov uas xav tau qhov tsawg.

③ JIS Qib

JIS qib yog lub ntsej muag precision iav cov qauv tsim los ntawm Japanese muaj cov qauv hauv 11, JIS 4 {, JIS 4 {, JIS 4 {, JIS 4 {, JIS 4 {? daim ntawv thov siab precision; Lub iav yog qhov tseeb ntawm JIS 10 yog qhov tsawg thiab feem ntau yog siv rau cov ntawv thov tsawg.
