Gear Accuracy Qib – Cov Qauv & Kev faib tawm

iavcov qhab nia raug txhais covkam rau ua thiab precision theemntawm cov iav raws li cov qauv thoob ntiaj teb (ISO, AGMA, DIN, JIS). Cov qib no ua kom cov meshing zoo, tswj lub suab nrov, thiab ua haujlwm zoo hauv cov tshuab iav

1. Gear Accuracy Standards

ISO 1328 Kev Tswj Xyuas Feem ntau

Txhais 12 qib raug (los ntawm siab tshaj mus rau qis tshaj precision):

Qib 0 txog 4 (Ultra-precision, xws li aerospace, metrology)

Qib 5 txog 6 (High precision, piv txwv li, automotive transmissions)

Qib 7 txog 8 (General industrial machinery)

Qib 9 txog 12 (Low precision, piv txwv li, khoom siv ua liaj ua teb)

AGMA 2000 & AGMA 2015 (US Standard)

Siv Q-tus lej (Qib Zoo):

Q3 rau Q15 (Q siab dua Q = zoo dua precision)

Q7-Q9: Feem ntau rau cov iav tsheb

Q10-Q12: High-precision aerospace / tub rog

DIN 3961 / 3962 (German tus qauv)

Zoo ib yam li ISO tab sis nrog cov kev faib ua siab ntev ntxiv.

JIS B 1702 (Japanese Txuj)

Siv Qib 0 txog 8 (Qib 0 = siab tshaj precision).

2. Ntsiab iav qhov tseeb Parameters

Cov qhabnias raug txiav txim los ntawm kev ntsuas:

1.Tooth Profile yuam kev (Deviation los ntawm zoo tagnrho involute nkhaus)

2. Pitch yuam kev (Variation nyob rau hauv cov hniav sib nrug)

3.Runout (Eccentricity ntawm iav rotation)

4.Lead yuam kev (Deviation in tooth alignment)

5.Surface Finish (Roughness cuam tshuam lub suab nrov & hnav)

3. Cov ntawv thov raug raws qib raug
