Splinesyog cov khoom siv tshuab tseem ceeb siv los xa cov torque ntawm shafts thiab mating qhov chaw xws li cov iav los yog pulleys. Txawm hais tias lawv yuav zoo li yooj yim, xaiv qhov raug spline hom thiab tus qauv yog qhov tseem ceeb rau kev ua haujlwm, kev sib raug zoo, thiab kev tsim khoom.
1. ISO Standards (International)

ANSI B92.2M- Metric version ntawm involute spline tus qauv (sib npaug rau ISO 4156).
3. DIN Standards (Lub teb chaws Yelemees)
TIAB SA 5480- German tus qauv rau metric involute splines raws li lub module system (dav siv nyob rau hauv cov teb chaws Europe).
TIAB SA 5482- Cov qauv qub rau kev nplua-module involute splines.
4. JIS Standards (Nyiv)
SIB 1603- Japanese tus qauv rau involute splines (sib npaug rau ISO 4156 thiab ANSI B92.2M).
5. SAE Standards (Automotive)
SAE J498- Npog suav nrog splines rau kev siv tsheb (ua raws li ANSI B92.1).
Cov ntsiab lus tseem ceeb ntawm Involute Splines:
1. Tus naj npawb ntawm cov hniav (Z)
● Tag nrho cov hniav ntawm lub spline.
● Muaj feem cuam tshuam rau kev sib kis torque thiab kev sib raug zoo nrog mating qhov chaw
2. Pitch Diameter (d)
● Txoj kab uas hla ntawm cov hniav thickness sib npaug ntawm qhov chaw dav.
● Feem ntau yog siv raws li txoj kab uas hla rau kev xam.
● Tseem ceeb rau kev txiav txim siab qhov haum thiab lub peev xwm torque.
3. Lub kaum sab xis siab (α)
● Cov nqi ntau:30 °, 37.5 ib°,,ua 45°
● Txhais cov duab ntawm cov hniav profile.
● Kev cuam tshuam kev sib cuag, lub zog, thiab rov qab.
4. Module (Metric) lossis Diametral Pitch (Inch):Txhais cov hniav loj.
5. Loj Diameter (D)
● Qhov loj tshaj txoj kab uas hla ntawm lub spline (ntsiab ntawm cov hniav sab nraud los yog cov hauv paus hniav ntawm cov hniav).
6. Qhov Loj (d₁)
● Qhov tsawg tshaj plaws txoj kab uas hla ntawm lub spline (hauv paus ntawm cov hniav sab nraud los yog cov hniav sab hauv).
7. Pem taub (d_b)
● xam raws li:
● Siv rau involute profile tiam.
8. Cov hniav Thickness thiab qhov chaw dav
●Cov hniav tuab(ntawm lub suab voj voog) yuav tsum sib phimqhov dav davntawm mating part.
● Muaj feem cuam tshuam rov qab thiab haum rau chav kawm (kev tshem tawm, kev hloov pauv, lossis cuam tshuam).
9. Daim Ntawv Pov Thawj (C_f)
● Qhov chaw ntawm lub hauv paus kom tso cai rau cov cuab yeej tshem tawm thiab tiv thaiv kev cuam tshuam.
● Tshwj xeeb tshaj yog tseem ceeb nyob rau hauv cov splines.
10. Haum rau chav kawm / kam rau ua
● Txhais qhov kev tshem tawm lossis cuam tshuam ntawm qhov chaw sib tw.
● ANSI B92.1 suav nrog cov chav kawm haum xws li Chav Kawm 5, 6, 7 (nce ntxiv nruj).
● DIN thiab ISO siv cov cheeb tsam kam rau ua (piv txwv li, H/h, Js, thiab lwm yam).
11. Lub ntsej muag dav (F)
● Axial ntev ntawm kev sib koom tes spline.
● Muaj feem cuam tshuam rau kev sib kis torque thiab hnav tsis kam.
Hom haum:
