Cov yam ntxwv thiab qhov tseem ceeb ntawm cov iav khib
Khibyog ib qho tshwj xeeb iav nrog cov hniav faib rau ntawm qhov bar. Racks kuj tau muab faib ua racks ncaj thiab helical racks, uas yog khub nrog ncaj thiab spur zog, feem; cov hniav profile ntawm cov khib nyiab yog ib txoj kab ncaj nraim es tsis txhob muaj ib qho involute (flat deg rau cov hniav nto), sib npaug rau cov iav cylindrical nrog lub voj voog infinite.
Tswv yim
Cov khib nyiab yog ib qho bar-zoo li qhov sib piv cov iav. Nws yog sib npaug rau ib feem ntawm lub voj voog ntawm ib lub iav nrog ib txoj kab uas hla tsis kawg. Ntau cov hniav sib npaug sib npaug ntawm ib sab, uas meshes nrog lub zog, tig tig mus rau hauv kev txav, los yog tig mus rau hauv kev sib hloov. Lub khib yog ntev thiab muaj cov hniav ntawm ib sab. Nws tuaj yeem raug suav hais tias yog ib feem ntawm lub iav nrog ib txoj kab uas hla tsis kawg.
Main feature
(1) Vim tias cov hniav khib nyiab yog txoj kab ncaj nraim, txhua lub ntsiab lus ntawm cov hniav profile muaj tib lub siab lub kaum ntse ntse thiab sib npaug rau lub kaum sab xis ntawm cov hniav profile. Lub kaum sab xis no yog hu ua tus hniav profile, thiab tus qauv tus nqi yog 20 degree.
(2) Txhua txoj kab ncaj nraim mus rau kab txuas ntxiv muaj tib lub suab thiab cov qauv.
(3) Ib txoj kab ncaj nraim mus rau kab saum toj kawg nkaus ntawm tus hniav thiab muaj cov hniav tuab sib npaug ntawm qhov dav ntawm cov hniav zawj yog hu ua kab sib faib (kab kab nruab nrab), uas yog cov kab siv rau kev suav cov khib nyiab loj.
Lub ntsiab tsis
Qhov tseem ceeb ntawm cov khib nyiab yog: hniav width,hniavaddendum, hniav denendum,hniav qhov siab, hniav thickness, hniav hauv paus vojvoog, thiab lwm yam.
Alveolar
Cov hniav zawj yog qhov concave ntawm cov hniav ntawm cov iav.
Qhov chaw nruab nrab ntawm ob cov hniav uas nyob ib sab ntawm lub iav yog hu ua cogging lossis inter-tooth. Qhov luaj li cas ntawm cov hniav zawj yog qhia los ntawm qhov dav ntawm qhov zawj, thiab qhov dav ntawm cov hniav zawj tuaj yeem muab faib ua ob hom: qhov zawj dav ntawm lub ntsej muag kawg thiab qhov dav ntawm qhov ib txwm zawj.
(1) Dav ntawm lub ntsej muag zawj (groove dav) - ntawm lub dav hlau kawg, qhov ntev ntawm qhov sib faib arc nruab nrab ntawm cov hniav profiles ntawm ob sab ntawm cov hniav zawj yog qhia los ntawm tsab ntawv e. Qhov dav dav ntawm txhua qhov ncig yog qhia los ntawm tsab ntawv ei.
(2) Qhov dav dav dav (qhov dav dav dav) - nyob rau hauv ib lub qhov ntawm lub helical iav, ib txwm muab kauv ntawm cov hniav kab ntawm ob sab ntawm kab helical yog nyob rau hauv qhov ntev ntawm lub qhov, hu ua lub qhov dav dav.
Ntxiv
Ib feem ntawm lub voj voog sib faib thiab lub voj voog ntxiv yog hu ua qhov ntxiv ntawm iav. Qhov kev ncua deb ntawm radial yog hu ua tus hniav qhov siab, thiab yog sawv cev los ntawm tsab ntawv ha. Qhov siab ntawm tus hniav ntxeev ntawm lub cylindrical iav yog xam los ntawm cov qauv hauv qab no:
Nyob rau hauv cov mis: ha — qhov siab coefficient ntawm cov hniav cylindrical iav, ha=1 rau cov hniav ib txwm, ha=0.8 rau cov hniav luv;
m-gear modulus.
Cov hniav cag
Qhov nruab nrab ntawm lub voj voog sib faib thiab lub voj voog ntawm cov hniav yog hu ua cov hauv paus hniav. Lub radial nrug yog hu ua lub hauv paus qhov siab, thiab yog sawv cev los ntawm tsab ntawv hf. Lub hauv paus qhov siab ntawm cylindrical iav yog xam raws li hauv qab no:
Nyob rau hauv cov mis, ha—qhov siab coefficient ntawm cov hniav ntawm lub cylindrical iav, ha=1 rau cov hniav ib txwm thiab ha=0.8 rau cov hniav luv;
C — Lub tog raj kheej iav sab saum toj clearance coefficient, C=0.25 rau cov hniav ib txwm, C=0.3 rau cov hniav luv;
m — modulus iav.
Kev nyiam
(1) Txawm hais tias lub iav runout, tag nrho cov hniav qhov tob, cov kab ib txwm, cov kev taw qhia ntawm cov hniav yog tsim nyog, ib tug hniav viav vias sib txawv, thiab seb lub circumferential sib koom ua yuam kev yog tsis kam.
(2) Txawm hais tias qhov kev ncua deb yog tsim nyog tom qab lub iav thiab khib tau teeb tsa.
(3) Lub meshing clearance ntawm khib thiab iav yuav tsum yog 0.25 * module.
(4) Txawm hais tias lub khib nyiab tag nrho cov hniav tob, qhov dej ntws tawm, qhov ib txwm muaj, tshwj xeeb tshaj yog cov kev taw qhia hniav yog tsim nyog.
