1. Kev xaiv cov iav thiab khib: lub modulus yog tus nqi qhia txog cov duab thiab qhov loj ntawm cov hniav ntawm cov iav. Kev sib txuas sib txuas tuaj yeem ua tau tsuas yog thaum lub modulus thiab siab lub kaum sab xis ntawm ob lub zog yog tib yam.
M=D / Z, qhov twg D yog txoj kab uas hla ntawm lub voj voog siv; Z yog tus naj npawb ntawm cov hniav. Qhov loj dua lub modulus, lub zog muaj peev xwm load.
Common modulus: {{0}}.5, 0.8, 1.0, 1.5, 2.0, 2.5, 3.0; Raws li daim ntawv thov tiag tiag, lub load quab yuam lub vojvoog ntawm kev siv lub voj voog kev nyab xeeb yuav tsum tsawg dua li qhov tso cai hloov lub zog.
Incidentally, txoj kab uas hla ntawm lub voj voog siv, uas yog, txoj kab uas hla ntawm lub voj voog sib faib, cuam tshuam rau kev txav ceev. Cov qauv kev suav tshwj xeeb yog:
w=2 Π n/60
v=wr
Qhov twg W yog angular tshaj tawm thiab N yog qhov kev sib hloov ceev, hauv R / min; R yog lub vojvoog ntawm lub voj voog sib faib.
Hauv kev siv tswv yim, peb feem ntau xaiv cov hniav oblique. Raws li kev sib piv ntawm cov hniav ncaj thiab oblique hniav, oblique hniav muaj qhov sib txawv hauv qab no:
ib. Kev ua haujlwm ruaj khov thiab lub suab nrov tsawg. Vim hais tias tsuas yog ib feem ntawm txhua tus hniav nto koom nyob rau hauv lub meshing txheej txheem ntawm helical iav, los yog nws yog to taub hais tias txhua tus hniav maj mam koom nyob rau hauv lub meshing thiab yuav tsis tsim loj kev co, lub suab yog tsawg.
b. Cov kabmob muaj peev xwm ntawm cov iav helical nrog tib lub qauv thiab qhov dav yog siab dua li ntawm cov iav spur, vim tias qhov zoo ntawm cov hniav dav ntawm cov iav helical yog qhov loj dua qhov no.
C. Vim tias muaj ntau qhov sib txuas meshing, qhov tseeb ntawm oblique cov hniav feem ntau zoo dua li cov hniav ncaj ntawm tib qib.
d. Vim tias cov iav helical tau sab laug - tes thiab sab xis - tes tig, kev taw qhia yuav tsum tau txiav txim siab thaum koom tes nrog cov khib nyiab. Feem ntau, sab laug - tes iav koom tes nrog txoj cai - tes khib.
e. Helix lub kaum sab xis yog qhov tshwj xeeb ntawm cov iav helical. Feem ntau hais lus, lub helix lub kaum sab xis ntawm helical iav peb feem ntau yog xa mus rau lub helix lub kaum sab xis ntawm lub indexing cylindrical nto. Qhov loj dua lub helix lub kaum sab xis yog, qhov ntau dua qhov coincidence degree yog, uas yog ntau conducive rau smooth txav thiab txo suab nrov. Txhua yam muaj ob sab. Txawm hais tias nce lub kaum sab xis helix coj ntau qhov zoo, lub zog axial generated thaum lub sijhawm ua haujlwm kuj nce. Yog li ntawd, qhov luaj li cas ntawm lub kaum sab xis ntawm lub helix yuav tsum nyob ntawm qhov kev xav tau zoo thiab kev ua haujlwm raug ntawm kev ua haujlwm. Feem ntau, nws yog 8-25. Yog tias muaj cov kev cai tshwj xeeb rau lub suab nrov, nws tuaj yeem raug coj los ua tus nqi loj dua raws li qhov xwm txheej.
2. Installation of gear rack: for long-distance transmission, when the rack is installed at the section, it must be installed with the gear gauge. In particular, rack suppliers usually leave two 7 holes at both ends. The purpose is to prevent the rack from moving in the later stage. I didn't use the actual pin holes in practical application, because the rack will be worn, and the accuracy in the later stage can't be reached, so it's difficult to debug. For gear installation, be sure to make a tensioning mechanism.
3. Lubrication thiab plua plav tiv thaiv ntawm iav khib: thaum lub sij hawm ntev - lub sij hawm ua hauj lwm ntawm iav khib, kev poob ntawm txawv teb chaws teeb meem thiab lubrication tsis txaus yuav ua rau cov iav hnav. Yog li ntawd, kev tiv thaiv plua plav thiab lubrication ntawm iav khib yuav tsum ua kom zoo. Txoj kev tiv thaiv plua plav feem ntau txhais tau tias yog daim ntawv hlau npog. Ntawm no, xyuam xim rau qhov resilience ntawm cov ntawv hlau. Cov npog uas nyob ib sab yuav tsum tau txuas nrog cov ntawv hlau, thiab qhov zoo ntawm cov khoom tsim los ntawm peb tus kheej yuav tsum yog qhov tsawg kawg nkaus. Rau lubrication, ob peb lub ntsiab lus yuav tsum tau ua: A. xaiv cov roj twj tso kua mis tsim nyog thiab xaiv cov roj twj tso kua mis tsim nyog raws li hom roj. Lub iav khib tsis xav tau roj txhua lub sijhawm. Xaiv cov roj sib txawv raws li cov roj sib txawv; b. Xaiv lub log paj rwb uas tsim nyog kom tsis txhob muaj cov hniav tsis sib haum;
