Gear Rack Cov Qib Siab: Dab tsi DIN 5, DIN 7 thiab DIN 10 Tus nqi tiag tiag rau koj

Iav khib thiab matched pinion, av hniav

Lub hom phiaj lo lus tseem ceeb:iav khib qhov tseeb qib

Secondary:DIN zoo chav kawm iav khib, khib thiab pinion backlash, iav khib pitch yuam kev

Meta piav qhia:DIN 5 txog DIN 10 iav khib qhov tseeb tau piav qhia nrog cov lej ntawm qhov yuam kev tiag tiag, ua tiav rov qab rau ib qib, thiab yuav ua li cas xaiv cov chav kawm yam tsis tau them nyiaj ntau dhau.

Txhua ob peb lub lis piam ib tug neeg xa peb daim duab rau ib lub khib thiab pinion gantry nrog "siab precision" sau rau hauv cov ntawv thiab tsis muaj dab tsi ntxiv. Tsis muaj DIN chav kawm, tsis muaj suab yuam kev daim duab, tsis muaj lub hom phiaj backlash. Thaum peb nug, cov lus teb feem ntau yog ib co version ntawm "yuav tsum tau raws li qhov ua tau hauv pob nyiaj siv."

Qhov ntawd tsis yog qhov tshwj xeeb. Nws yog kev xav. Thiab qhov sib txawv ntawm DIN 10 thiab DIN 5 tsis yog tus nqi me me - nws yog txoj kev tsim khoom sib txawv, lub tshuab sib txawv, thiab ntau zaus tus nqi ib meter.

Yog li ntawm no yog qhov qhab nia txhais tau li cas, hauv cov lej, thiab yuav txiav txim siab li cas koj lub tshuab xav tau tiag tiag.

Tus naj npawb ntsuas li cas

Lub khib nyiab qhov tseeb qib piav qhia txog qhov yuam kev ntawm qhov sib tw - deb npaum li cas cov hniav txav los ntawm lawv txoj haujlwm theoretical raws qhov ntev ntawm qhov bar. Nws yog ib txwm hais nyob rau hauv millimeters ib 'meter'.

Daim duab 1. Kev ua yuam kev ntawm DIN cov chav kawm zoo. Qib ua tiav yam tsis muaj kev tshaj tawm - sib tsoo tawv yog pom hauv txiv kab ntxwv.

DIN 3962 txhais cov chav kawm zoo; tus lej qis dua, qhov nruj dua qhov kam rau ua. Thoob plaws hauv kev lag luam, txoj kev tsim khoom thiab cov chav kawm ua tiav tau zoo li no:

Peb tsim racks thoob plaws ntau yam no, DIN 5 txog DIN 10.

Qhov sib kis ntawm sab saum toj mus rau hauv qab yog kwv yees li 8: 1. Txhawm rau muab tso rau hauv cov ntsiab lus ntawm lub cev: lub khib nrog ± 0.200 mm pitch sib txawv tshaj 1,000 mm txhais tau hais tias qhov ntev tiag tiag thaj av ntawm 999.8 mm thiab 1000.2 mm tawm tsam qhov theoretical 1,000 mm.

Pom ib yam dab tsi hauv lub rooj. Induction- hardened yooj yim racks zaum ntawm DIN 10 - lubphem tshajqib tau teev tseg - thaum hardened-thiab- hauv av racks ncav cuag DIN 5. Ob leeg yog hardened. Qhov txawv yog dab tsi tshwm sim tom qab hardening.

Vim li cas hardening ua racks tsawg dua, tsis ntau

Qhov no ua rau tib neeg mus tas li. Hardening yog ib qho kev ua haujlwm zoo, yog li qhov tseeb ntawm cov khib nyiab yog qhov khib nyiab zoo dua?

Rau load peev, yog. Rau qhov tseeb, tsis muaj - tsis yog ntawm nws tus kheej.

Induction hardening dramatically tsub kom lub zog muaj peev xwm ntawm ib tug khib, thiab nyob rau tib lub sij hawm txo cov hniav zoo, vim hais tias lub cua sov thiab quenching voj voog deforms lub bar.

Cua sov cov hniav kom austenitising kub thiab quenching lawv ua rau lub bar txav. Ib lub khib nyiab ntev ntev yog hais txog qhov phem tshaj plaws geometry rau tiv thaiv qhov kev tsis sib haum xeeb. Koj tau txais 50-55 HRC ntawm cov flanks thiab koj poob qhov tseeb hauv tib txoj haujlwm.

Qhov kho yog zom cov hniavtom qabtawv. Qhov ntawd yog qhov sib cais DIN 10 induction-cov khib nyiab los ntawm DIN 6 hardened-thiab- hauv av khib - ib qho ntxiv precision sib tsoo hla ntawm lub tshuab uas raug nqi ntau dua li cov neeg feem ntau lub tsev. Tib lub hauv paus ntsiab lus tuav rau lub zog feem ntau: qhov tseeb poob tom qab kev kho cua sov, thiab kev sib tsoo yog li cas nws rov qab los.

Hauv peb tus kheej tsim tawm qhov no yog kev txiav txim siab npaj, tsis yog tom qab. Cov khoom lag luam ntxiv yog sab laug thaum cov hniav milling tshwj xeeb kom cov hniav tuaj yeem rov qab mus rau qhov loj me tom qab hardening. Lub khib tau hais tias "hardened" yam tsis muaj kev sib tsoo tom qab nws tsis tuaj yeem tuav cov chav kawm siab, txawm li cas los xij lub hardness daim duab hais.

Qhov no kuj yog vim li cas "hardened" ib leeg qhia koj tsis muaj dab tsi txog precision. Nug cov txheej txheem twg, thiab seb cov hniav puas yog av tom qab ntawd.

Tus naj npawb koj lub tshuab yeej xav tias: backlash

Pitch yuam kev yog qhov tau txais ntawv pov thawj. Backlash yog dab tsi tus neeg teb xov tooj ceeb toom thaum lub axis thim rov qab.

Daim duab 2. Qhov tsawg kawg nkaus ua tiav backlash los ntawm qhov system precision theem.

Yam tsawg kawg nkaus ua tiav backlash los ntawm qhov system precision theem:

Ib qho kev tsim nyog siv rau txhua kab ntawm lub rooj, thiab nws yog kab lus tseem ceeb tshaj plaws ntawm cov ntsiab lus:khib thiab pinion backlash nyob ntawm qhov kev sib tw ntawm cov khib nyiab mus rau cov kev qhia tawm.

Nyeem qhov ntawd dua ua ntej koj xaj DIN 5 khib. Yog tias koj lub khib nyiab mounting nto tsis machined thaum uas tig mus rau cov kab ntawv qhia, qhov chaw nruab nrab ntawm lub pinion sib txawv raws li tus mob stroke, thiab backlash txawv nrog nws. Koj yuav tau yuav ultra-siab precision thiab nruab nruab nrab precision. Peb tau pom qhov no tshwm sim ntawm cov cav tov uas cov khib nyiab raug nqi ntau dua li lub gearbox.

Zero backlash tsis ua tiav los ntawm kev yuav lub khib zoo dua. Nws los ntawm kev sib koom ua ke - yog ib qho kev sib cais, qhov twg ob lub pinion halves raug thawb sib nrug los ntawm lub caij nplooj ntoos hlav pob kom txhua ib nrab thauj cov hniav rov qab, lossis ib qho hluav taws xob preloaded dual - pinion teeb nrog tus tswv thiab qhev tsav.

Qib xaiv los ntawm daim ntawv thov

Ua haujlwm rov qab los ntawm qhov xav tau qhov tseeb qhov tseeb yog tib txoj kev zoo.

DIN 9-10, mos lossis induction hardened.Cov rooj vag zawv zawg, nqa yooj yim thiab hloov chaw, nres, vuam positioners, txhua yam uas ib feem kaum ntawm ib millimeter tsis cuam tshuam. Kev siv ntau ntawm no yog nyiaj hlawv.

DIN 8, quenched thiab tempered.Gantry loaders, palletisers, neeg hlau xya axis, kev tuav dav dav. Qhov tseeb ntawm qhov chaw nyob hauv thaj tsam 0.1 hli nrog tus nqi tsim nyog.

DIN 6-7, hardened thiab av.CNC routers, plasma thiab laser txiav gantries, machining chaw axes. Qhov no yog qib qhov kev txiav zoo pib nyob ntawm lub khib es tsis yog lub voj voog tswj.

DIN 5, hardened thiab av.Cov tshuab sib tsoo, ntsuas tshuab, siab -kawg tshuab cov cuab yeej nrog cov kab tawm. Qhov no yog qhov saum toj kawg nkaus ntawm peb qhov ntau lawm thiab qhov taw tes uas txhua lwm yam nyob rau hauv axis - cov lus qhia, mounting nto, gearbox - yuav tsum nyob rau tib theem lossis qib khib nyiab pov tseg.

Nws muaj ib qho counter-intuitive point tsim nyog absorbing, thiab nws los txog hauv khib sizing kev taw qhia thoob plaws hauv kev lag luam:

Ib tug loj module tsis cia li txhais tau tias siab dua transmissible quab yuam. Ib qho module 2 khib hauv chav kawm zoo 5 tuaj yeem xa cov tangential quab yuam ntau dua li module 3 khib hauv chav kawm 8.

Qhov tseeb zoo dua txhais tau tias kev thauj khoom kis thoob plaws cov hniav ntau dua hauv kev sib cuag. Ib co ntxhib tab sis sloppy khib concentrates quab yuam ntawm qhov twg cov hniav tshwm sim kom siab. Kev nce mus rau qhov loj me kom tau txais lub zog thaum poob qib zoo tuaj yeem ua rau koj tsis zoo dua li qhov koj pib.

Kev mus ncig ntev: vim li cas qib ib leeg tsis txiav txim siab tag nrho

Rau kev mus ncig dhau ib qhov ntev ntawm khib, qhov sib koom ua yuam kev tseem ceeb npaum li qib khib.

Hardened thiab hauv av helical khib nrog mounting qhov

Tus neeg sawv cev rau -rack cumulative pitch yuam kev ntawm qhov ntev sib txawv:

Qhov yuam kev tsis ntsuas linearly nrog ntev - ib 2,000 mm DIN 6 khib tuav 0.044 mm tag nrho, uas tsuas yog 0.022 mm ib meter, zoo dua li 0.034 mm ntawm 1,000 mm khib ntawm ib -meter hauv paus.

Qhov ntawd muaj qhov cuam tshuam ncaj qha rau rau 6 meters ntawm kev mus ncig. Siv DIN 6 module 4 helical racks thiab kev sib koom ua ke tuav hauv qab 0.025 hli ib leeg:

3 × 2,000 hli racks → 3 × 0.044 + 2 × 0.025 =0.182 hlitag nrho, 2 leeg

6 × 1,000 hli racks → 6 × 0.034 + 5 × 0.025 =0, 329 mmtag nrho, 5 leeg

12 × 500 hli racks → 12 × 0.026 + 11 × 0.025 =0, 587mmtag nrho, 11 leeg

Tib qib, tib qhov ntev tag nrho, thiab luv - kev xaiv khib yog ntau dua peb zaug. Cov pob qij txha dominate. Tsawg dua, ntev racks yeej ntau dua, luv dua txhua zaus - yog vim li cas peb thawb cov neeg siv khoom mus rau 2 meter seem thaum twg lub tshuab txaj tso cai tuav lawv.

Yuav tso dab tsi rau koj qhov kev nug

Xa peb tsib yam no thiab koj yuav tau txais ib lub khib uas haum lub tshuab es tsis txhob ntawm daim ntawv qhia kev lag luam:

Module thiab lub ntsej muag dav- los yog lub zog tangential thiab peb yuav loj nws

Ncaj los yog helical

Kev kho cua sov, thiab seb cov hniav puas yog av tom qab hardening

Tag nrho kev mus ncig thiab seb koj npaj yuav koom nrog ntu twg

Yog tias koj tsuas paub qhov tseeb ntawm qhov chaw koj lub tshuab yuav tsum tau ntaus, qhia rau peb tias thiab cov kab ntawv qhia kev teeb tsa. Ua hauj lwm rov qab los ntawm daim ntawv thov yog ib txwm xyaum thiab siv ib tug email.

FAQ

Puas yog DIN 6 ob zaug zoo li DIN 8?

Ntawm lub suab yuam kev, zoo dua li ob zaug: 0.036 mm / m tawm tsam 0.100 mm / m. Ntawm cov khoom xa khoom raug, tsuas yog mounting thiab kev sib dhos txhawb nqa nws.

Kuv puas tuaj yeem sib xyaw DIN 6 khib nrog DIN 8 pinion?

Tsis sensibly. Lub hardness thiab zoo chav kawm ntawm tus pinion yuav tsum yeej ib txwm sib npaug los yog ntau tshaj ntawm cov khib, vim hais tias tus pinion pom deb tshaj kev sib cuag mus rau ib meter ntawm kev mus los.

Puas yog ib lub khib nyiab khov ntev dua li hauv av?

Kev sib piv tsis raug - cov no yog cov haujlwm sib txawv. Hardening teev hnav tsis kam thiab muaj peev xwm thauj khoom; sib tsoo teev raug. Lub hardened-thiab- hauv av khib muaj ob qho tib si.

Dab tsi backlash kuv tuaj yeem xav tau hauv kev xyaum?

Nruab nrab ntawm cov duab nyob rau hauv lub rooj saum toj no thiab roughly muab ob npaug rau lawv, nyob ntawm seb mounting. Cov txiaj ntsig no xav tias cov khib nyiab tau ua raws li cov lus qhia linear kom raug.

Puas yog cov qhab nia sib piv ntawm cov neeg muag khoom?

Tsis nruj npaum li koj yuav cia siab - thiab qhov ntsuas qhov ntev yog lub cuab tam li qub. Qee cov neeg muag khoom hais tag nrho qhov sib txawv ntawm 300 hli es tsis txhob ntawm 1,000 hli, uas ua rau tib lub khib nyiab zoo dua peb zaug. Ib txwm lees paub qhov ntsuas hauv paus ua ntej sib piv cov lus hais.
