Pob zeb diamond sib tsoo Log rau iav sib tsoo

1. Qhov zoo ntawm spur iav thiab kis tau tus mob: yooj yim tsim, yooj yim los ua ke, ncaj qha kev koom tes yam tsis muaj synchronizer, thiab ncaj qha siv cov sib sib zog nqus groove pob bearings rau ncej kawg installation, yeej tsis muaj axial quab yuam.
Qhov tsis zoo ntawm spur iav thiab kis tau tus mob: qhov ncaj iav kis tau tus mob tsis zoo, yooj yim los tsim kev cuam tshuam, kev co thiab suab nrov. Yog li ntawd, nws tsis haum rau kev kub ceev thiab lub luag haujlwm hnyav.

2. Helical iav thiab kis tau tus mob zoo: lub helical iav meshing yog maj mam nqa tawm, cov hniav sib cuag degree yog loj (zoo meshing hniav), lub load tsis dheev ntxiv los yog tshem tawm, yog li cov kis tau tus mob yog ruaj khov, tsis tshua muaj suab nrov, ntev kev pab cuam lub neej. , dav siv nyob rau hauv kev kub ceev thiab hnyav lub luag hauj lwm zaus.
Qhov tsis zoo ntawm helical iav thiab kis tau tus mob: thaum tsim khoom yog me ntsis nyuaj, muaj ntau lub zog axial ntawm kev ua haujlwm, uas tsis zoo rau cov kabmob.

Yog li ntawd, thawj lub iav thiab rov qab iav ntawm lub tsheb gearbox yog siv rau kev lag luam thiab compactness vim lawv tsis ua hauj lwm rau lub sij hawm ntev thiab qhov ceev tsis siab. Thaum lwm lub zog thiab lub qag nram qab muaj qhov yuav tsum tau ua kom du vim tias kev ua haujlwm siab, yog li siv cov iav helical. Txhawm rau txo cov kev cuam tshuam ntawm axial quab yuam, cov iav hniav sib hloov offset thiab cov txheej txheem tsim cov iav hloov tau txais, yog li cov hniav profile nrog taper tuaj yeem txo cov kabmob muaj peev xwm thiab tswj kev ua haujlwm du.

Raws li cov cuab yeej siv thev naus laus zis ntawm kev ua haujlwm siab thiab cov hniav tawv tawv ua tiav, daim ntawv thov ntawm iav sib tsoo tshuab tau dhau los ua neeg nyiam. Feem ntau hais lus, kev sib tsoo hniav yog cov hniav zoo li txheej txheem ntawm iav qhov chaw. Nws yog cov txheej txheem kho hniav uas tshem tawm cov nyiaj ua tiav ntawm lub hauv paus ntawm kev ua tiav cov txheej txheem ntawm cov hniav (xws li hobbing thiab milling hniav thiab lwm yam) thiab kev kho cua sov, txhawm rau txhim kho qhov tseeb thiab qhov zoo ntawm cov iav.

Kev cuam tshuam ntawm cov hniav precision ntawm cov hniav sib tsoo:

Txhawm rau kom ntseeg tau tias lub log sib tsoo nkag mus rau hauv cov hniav kom raug thiab sib npaug ntawm qhov sib tsoo ntawm cov hniav sab laug thiab sab xis, lub iav sib tsoo tshuab yuav tsum tau nqa tawm qhov chaw ncig ntawm qhov chaw ua ntej sib tsoo lawv.

Nws yog ib qho tsim nyog los xyuas kom meej tias qhov chaw nruab nrab ntawm cov hniav zawj coincides nrog qhov chaw nruab nrab ntawm cov xuab zeb iav hniav profile. Tom qab raug kev sib tsoo thawj tus hniav zawj, lub tshuab cuab yeej yuav ua kom sib cais cov hniav workpiece thiab zom tawm tag nrho cov hniav.

Raws li tau pom los ntawm daim duab 1: yog tias qhov chaw ua haujlwm ntawm qhov chaw ua haujlwm tsis raug ua ntej sib tsoo, qhov loj ntawm qhov sib tsoo ntawm ob sab ntawm cov hniav zawj yuav tsis sib npaug. Kev sib tsoo loj loj yuav cuam tshuam ncaj qha rau cov hniav thiab zom cov khoom ua haujlwm rau hauv khib nyiab lossis txawm tias ua rau poob ntawm qhov tseeb ntawm lub tshuab cuab yeej.

Qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv yuav cuam tshuam ncaj qha rau cov hniav ntawm kev sib tsoo tom ntej, yog li qhov sib tsoo tiag tiag yuav tsum tau txiav txim siab raws li sab nrog cov npoo loj, uas ua rau nce ntawm radial pub lub sij hawm, yog li txo cov machining efficiency.
Tsis tas li ntawd, qhov nyiaj tsis sib xws yuav ua rau cov nyiaj pub dawb rau ntawm ib sab ntawm qhov tseeb sib tsoo txheej thickness ntau dua li qhov theoretical tus nqi, rau carburizing los yog nitriding tshav kub kev kho mob ntawm cov hniav hardening iav, vim hais tias lub nto hardening txheej yog ntiav, tiag tiag sib tsoo thickness yuav nce. ua rau cov khoom tiav ntawm cov hniav hardness tsawg, ua rau qhov teeb meem tsis zoo lossis cuam tshuam rau qhov kev ua tau zoo.

Sib tsoo log xaiv:

Kev xaiv ntawm kev sib tsoo log feem ntau txiav txim siab abrasive, particle loj, hardness, bonding agent thiab lwm yam.

Abrasive: sib tsoo log abrasive xaiv yog feem ntau cuam tshuam nrog cov khoom siv thiab kev kho cua sov, hardness. Kev sib tsoo log yuav tsum muaj siab hardness, hnav tsis kam, kub tsis kam thiab toughness, nrog rau cov ces kaum ntse rau txiav hlau.

Super tawv abrasive: feem ntau yog pob zeb diamond, dag pob zeb diamond, cubic boron nitride, thiab lwm yam., kev sib tsoo ntawm siab hardness, nkig cov ntaub ntawv. Tib lub sijhawm, pob zeb diamond abrasives kuj tuaj yeem siv los ua cov cuab yeej sib tsoo log.

Corundum thiab ceramic abrasives raug pom zoo rau carburizing thiab hardening iav hniav sib tsoo.

Particle loj: Particle loj hais txog qhov loj ntawm kev sib tsoo log grain loj. Qhov me me ntawm kev sib tsoo log grain loj yog, qhov me me ntawm qhov loj me yog. Ntawm qhov tsis sib xws, qhov loj dua particle loj hom. Kev xaiv ntawm kev sib tsoo log loj yog ncaj qha ntsig txog lub sijhawm machining thiab qhov roughness ntawm cov hniav thaum lub iav sib tsoo.

Daim ntawv thov tej yam kev mob ntawm coarse grain sib tsoo log:

Coarse-grained sib tsoo log yog xaiv rau kev sib tsoo raws li hauv qab no:

(1) qhov chaw nrog siab toughness thiab tsawg hardness.

(2) cov ntaub ntawv uas tsis zoo thermal conductivity thiab yooj yim rau hlawv.

(3) Thaum cov khoom noj muaj ntau heev.

(4) Thaum qhov roughness ntawm tus hniav nto tsis siab, uas yog, nyob rau hauv lub premise ntawm ua tau raws li qhov yuav tsum tau roughness, coarse-grained sib tsoo lub log yuav tsum tau xaiv kom deb li deb li sai tau.

(5) Thaum qhov chaw sib chwv ntawm cov hniav thiab kev sib tsoo loj, lub log sib tsoo nrog qhov loj me me yuav tsum raug xaiv kom tsis txhob muaj cua sov ntau dhau thaum sib tsoo los ntawm kev sib tsoo kub.

Fine grain sib tsoo log siv tau tej yam kev mob:

Nyob rau hauv cov xwm txheej hauv qab no, lub finer grain sib tsoo log yog xaiv rau kev sib tsoo:

(1) Thaum lub sij hawm cov hniav sib tsoo, qhov tuav ntawm lub log yog txhim kho kom ntseeg tau tias cov hniav sib tsoo ntau dua.

(2) thaum lub roughness ntawm cov hniav yog siab dua.

(3) Sib tsoo qhov chaw nrog cov hniav me me.

Lub log sib tsoo nrog cov nplej loj ntawm 46 ~ 80 yuav tsum tau xaiv rau cov khoom siv carburized thiab hardened iav thaum sib tsoo, uas tuaj yeem ua rau thaj chaw sib cuag ntawm cov hniav sib tsoo thiab cov hniav thiab txo qhov roughness ntawm cov hniav. Nyob rau tib lub sijhawm, lub log sib tsoo yuav tsum muaj qee qhov chaw ua haujlwm siab kom ntseeg tau cov nti tshem tawm thiab kev ua haujlwm kub dissipation.

Hardness: Lub hardness ntawm kev sib tsoo log yog hais txog qhov nyuaj rau kev sib tsoo nplej ntawm qhov chaw sib tsoo log kom tawg los yog poob ntawm daim ntawv cog lus nyob rau hauv qhov kev txiav txim ntawm axial thiab radial quab yuam ntawm lub tshuab cuab tam thaum lub sib tsoo log tig ntawm ib tug ceev ceev thaum lub sij hawm. iav sib tsoo.

Lub hauv paus ntsiab lus dav dav rau xaiv kev sib tsoo lub log yog raws li hauv qab no:

(1) Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau sib tsoo, lub log sib tsoo tuaj yeem siv los ua cov txheej txheem uas tsis tshua muaj zog.

(2) Rau cov hniav uas tsis tshua muaj thermal conductivity thiab cov khoom rhiab heev rau thermal kub, mos sib tsoo log yog xaiv.

(3) Thaum txoj kab nrawm ntawm kev sib tsoo lub log yog siab, lub log sib tsoo yog siv.

(4) Txhawm rau txhim kho kev sib tsoo, kev sib tsoo mos tuaj yeem raug xaiv.

Lub hauv paus ntsiab lus dav dav rau kev xaiv nyuaj sib tsoo log yog raws li hauv qab no:

(1) Thaum cov hniav sib tsoo nyob rau hauv lub xeev tsis tu ncua, yuav tsum tau xaiv lub log sib tsoo nyuaj.

(2) Txhawm rau kom muaj kev sib tsoo zoo dua, kev sib tsoo nyuaj tau xaiv. Thaum carburizing thiab hardening iav yog sib tsoo, lub sib tsoo log nrog nruab nrab hardness yog xaiv.

Bonding agent: bonding agent yog cov khoom abrasive sib txuas ua ke. Lub zog, cuam tshuam tsis kam thiab kub tsis kam ntawm kev sib tsoo log feem ntau yog nyob ntawm hom thiab qhov xwm txheej ntawm tus neeg sawv cev sib tsoo ntawm lub log sib tsoo.

Rau carburized thiab hardened iav sib tsoo, vitrified pob zeb diamond sib tsoo log yuav tsum tau xaiv.
