Dab tsi yog Backlash hauv Rack thiab Pinion Systems? Yuav ua li cas kho nws rau qhov tseeb thiab kev pab lub neej

Thaum cov khib nyiab thiab pinion koom nrog, ib qho kev tshem tawm yuav tsum muaj nyob nruab nrab ntawm qhov tsis yog - tsav cov hniav. Qhov kev tshem tawm no yog hu uarov qab.

Backlash muab qhov chaw tsim nyog rau:

Lubricating zaj duab xis tsim

Kev tsim khoom tolerances

Installation deviations

Thermal expansion thaum ua haujlwm

Ib qho kev sib kis nrog xoom rov qab yuav muaj kev khi lossis qaug dab peg thaum kub hloov lossis teeb meem teeb meem tshwm sim.

Txawm li cas los xij, ntau dhau backlash tuaj yeem tsim:

Rov qab positioning yuam kev

Kev cuam tshuam thaum hloov kev taw qhia

Txo cov lus tsa suab raug

Yog li ntawd, lub hom phiaj tsis yog kom tshem tawm backlash kiag li, tab sis tswj nws nyob rau hauv ib tug haum ntau yam raws li daim ntawv thov yuav tsum tau.

Thaum lub tshuab hloov kev txav mus los, lub cev muaj zog tuaj yeem tig thaum lub rooj ua haujlwm nyob ib ntus. Qhov kev ncua no yog ib qho piv txwv ntawmrov qab backlash yuam kev.

Kev rov qab ntau dhau kuj tseem tuaj yeem ua rau:

Ua suab nrov thaum acceleration thiab deceleration

Cov hniav tsis sib xws

Txo qhov chaw rov ua dua

Feem ntau ua rau muaj xws li:

Ntau tshaj khib thiab pinion center nrug

Khib los yog pinion hniav hnav

Iav reducer backlash

Cov kabmob looseness

Kev txhim kho tsis zoo

Rau qhov kev ua kom zoo tshaj plaws, kev rov qab los ntawm cov khoom sib txawv yuav tsum tau muab cais thiab ntsuas tus kheej.

Cov backlash tsawg dhau tuaj yeem ua teeb meem xwb.

Cov tsos mob xws li:

Nce khiav tsis kam

Siab zog tam sim no

Localized cua sov

Suab nrov nrov

Hniav qhov chaw qhab nia los yog hnav

Ib qho yuam kev feem ntau yog kho ib txoj hauj lwm kom txog thaum zoo li "zero clearance." Yog tias cov khib nyiab ncaj, qhov tseeb, lossis cov pinion runout tsis tswj, lub kaw lus yuav nruj los yog jam ntawm lwm txoj haujlwm raws li kev mus ncig.

High precision tsis txhais hais tias yuam cov iav khub rau hauv qhov kev sib tw nruj tshaj plaws.

Txhawm rau ntsuas qhov system backlash kom raug:

Nruab ib lub dial taw qhia ntawm lub rooj txav los yog pinion tso zis sab.

Siv me me rau pem hauv ntej thiab rov qab txav.

Sau cov tswv yim txav ua ntej lub load pib teb.

Thaum ntsuas, paub qhov txawv ntawm:

Khib thiab pinion hniav backlash

Iav reducer backlash

Coupling looseness

Cov kabmob clearance

Kev ntsuas yuav tsum rov ua dua ntawm ntau txoj haujlwm raws li tag nrho lub sijhawm mus ncig. Qhov no yuav pab txiav txim seb qhov teeb meem yog tshwm sim los ntawm:

Tag nrho cov teeb meem kho

Local installation yuam kev

Rack straightness variation

Cov ntawv thov sib txawv yuav tsum muaj kev hloov kho sib txawv.

Standard Systems

Backlash feem ntau tuaj yeem hloov kho los ntawm:

Hloov khib thiab pinion center nrug

Siv cov kev hloov kho shims

Siv eccentric bearing kev txhawb nqa

High -Precision Systems

Cov kev daws teeb meem tshaj lij muaj xws li:

Dual pinion preload systems

Split pinions

Caij nplooj ntoos hlav-loaded anti-backlash mechanisms

Electronic dual- tsav tsheb them nyiaj

Txawm li cas los xij, cov kev daws teeb meem ua ntej nce kev thauj khoom tas mus li ntawm:

iav hniav

Cov kabmob

Lub cev muaj zog

Yog li ntawd, preload design yuav tsum xav txog:

Rated load peev

Lubrication tej yam kev mob

Thaum tshav kub kub tiam

Yuav tsum tau kev pab lub neej

Backlash sib xws yog cuam tshuam los ntawm ntau yam khoom siv tshuab, suav nrog:

Khib mounting nto straightness

Joint pitch precision nruab nrab ntawm cov khib nyiab

Pinion radial runout

Ncej rigidity

Cov kabmob txhawb qhov tseeb

Lub lubrication tsis txaus ua rau cov hniav hnav thiab ua rau cov tawv nqaij rov qab nce ntxiv thaum lub sijhawm.

Tom qab installation, cov txheej txheem pom zoo yog:

Ua haujlwm qis- nrawm puv - mob stroke.

Tshawb xyuas lub suab nrov, tiv thaiv, thiab kub.

Maj mam nce ceev thiab thauj khoom.

Saib xyuas backlash hloov thaum lub sijhawm ua haujlwm.

Kev tshuaj xyuas tsis tu ncua pab txheeb xyuas qhov hnav ua ntej kev ua haujlwm hnyav tshwm sim.

Yog hais tias tus hniav nto qhia:

Hnav tsis sib xws

Pitting

Yas deformation

Qhov tseem ceeb txo cov hniav tuab

yooj yim kho qhov chaw nyob deb tsis tuaj yeem rov qab tau cov kev sib cuag zoo.

Txuas ntxiv kom nce preload lossis txo qhov kev tshem tawm tuaj yeem ua kom pom tseeb lub nra ntawm thaj chaw puas thiab ua kom tsis ua haujlwm.

Nyob rau theem no, qhov system tiav yuav tsum tau soj ntsuam, suav nrog:

Khib mob

Pinion mob

Qhia qhov system

Cov kabmob

Lubrication mob

Hauv ntau qhov xwm txheej, kev hloov khib nyiab thiab pinion yuav tsum raug suav hais tias yog qhov sib txuam.

Kev tswj kom zoo backlash yuav tsum muaj qhov sib npaug ntawm qhov chaw qhov tseeb, kev ua haujlwm ruaj khov, thiab lub neej tivthaiv.

Tianjin Ounaida Precision Motion Cheebtsammuab rack thiab pinion daws raws li:

Module

Lub kaum sab xis

Cov hniav profile

Cov kev cai raug

Installation drawings

Kev ua haujlwm tiag tiag

Rau kev daws teeb meem backlash, cov neeg siv khoom tau txhawb kom muab:

Cov ntaub ntawv ntsuas kev mus ncig tag nrho

Hnav cov duab

Transmission qauv drawings

Ntog khib thiab pinion specifications

Cov ntaub ntawv no tso cai rau cov engineers los txheeb xyuas qhov tseeb ua rau muaj teeb meem backlash thiab pom zoo cov kev daws teeb meem zoo tshaj plaws.
