T5 lossis AT5? Lub Sijhawm Siv Hniav Profiles piv nrog qhov loj me

Muaj sij hawm siv sij hawm thiab matched pulley profiles

Lub hom phiaj lo lus tseem ceeb:sij hawm siv hniav profile sib piv

Secondary:AT5 vs T5 sij hawm siv, sij hawm siv lub suab daim ntawv qhia, AT profile sij hawm siv

Meta piav qhia:T thiab AT lub sij hawm siv txoj siv sia sib koom tib lub suab tab sis txawv txog li 54% hauv cov hniav dav. Tag nrho qhov ntev lub rooj los ntawm cov chaw tsim khoom cov ntaub ntawv thiab vim li cas cov profiles tsis sib hloov.

T5 thiab AT5 ob leeg muaj 5 hli suab. Lawv ob leeg yuav haum ib ncig ntawm lub pulley nrog 5 hli hniav sib nrug. Lawv tsis yog tib txoj siv, thiab kev sib pauv ib qho rau lwm tus yuav raug nqi koj lub peev xwm thauj khoom lossis qhov chaw raug.

Qhov sib txawv yog nyob rau hauv cov hniav, thiab nws loj dua li cov neeg feem coob xav tau.

T profile - lub hauv paus trapezoidal

Standard T profile qhov ntev:

Hauv qab hniav dav: T2.5=1.50 hli, T5=2.65 hli, T10=5.30 hli, T20=10.15 hli.

T profile yog tus qauv metric trapezoidal - xyoo caum ntawm lub hauv paus ntsia, dav stocked, pheej yig.

AT profile - siab heev T

Standard AT profile qhov ntev:

\5.0 hli rau ALPHA TORQUE thiab ALPHA POWER siv *

Hauv qab hniav dav: AT5=3.62 hli, AT10=7.33 hli, AT20=14.66 hli.

Qhov txawv, quantified

Ntawm 20 mm pitch tus AT tus hniav yog ntau tshaj ib nrab dua li dav li tus hniav T. Tib lub suab, tib tus hniav qhov siab, fundamentally txawv hniav.

Daim duab 1. Hniav dav thiab hauv paus dav, T tiv thaiv AT profile ntawm tib lub suab.

Vim li cas cov hniav dav dua

Engineering rational:

Txoj siv AT muaj cov hniav dav tshaj plaws ntawm tag nrho cov trapezoidal profiles, thiab yog li ntawd qhov siab tshaj plaws hniav shear kuj thiab lub siab tshaj plaws tso cai rau cov hniav quab yuam. Cov hniav tsis tshua muaj deformation, cov hlua muaj zog thiab cov nraub qaum qis ua ke muab qhov tseeb ntawm qhov chaw nyob hauv kev thauj khoom hauv linear drives. "

Peb txuas los ntawm ib qho kev hloov pauv geometric.

Shear tsis kam.Ib txoj siv hniav tsis ua tiav los ntawm kev txiav ntawm nws cov hauv paus hniav. Shear peev xwm yog proportional rau hauv paus ntoo khaub lig-section, thiab AT lub hauv paus yog 36-44% wider.

Cov hniav deformation.Ib tug dav, tawv hniav deflects tsawg nyob rau hauv load. Deflection ploj lawm - lub pulley tig thiab txoj siv tseem tsis tau txav mus vim tus hniav tseem compressing.

Positioning raug nyob rau hauv load.Qhov no ua raws ncaj qha. Ntawm txoj kab ncaj nraim, T- txoj siv hlua profile deflects ntau dua rau ib chav tsev ntawm kev quab yuam, yog li txoj haujlwm yuam kev sib txawv nrog kev thauj khoom. Ib txoj siv AT nrog tib lub suab tuav txoj haujlwm zoo dua, tsis yog vim nws tau tsim ntau dua, tab sis vim tias nws cov hniav tawv dua.

Qhov kawg taw tes yog vim li cas AT dominates linear positioning. Qhov zoo dua tsuas yog tshwm nyob rau hauv load - ib qho kev sib piv unloaded qhia tsis muaj dab tsi.

Qhov chaw zaum sib txawv - thiab vim li cas lawv tsis sib hloov

Yuav ua li cas tus hniav AT zaum hauv lub pulley:

AT10 profile timeing pulley

Tsis zoo li lwm yam trapezoidal profiles, AT tus hniav so ntawm nws lub taub hau cheeb tsam nyob rau hauv cov hniav khoob ntawm lub pulley. Lub taub hau hniav loj kuj txo qhov hnav thiab ua kom muaj peev xwm thauj khoom hauv cov khoom siv thauj khoom, vim tias qhov siab ntawm txoj siv thiab cov kev txhawb nqa yog qis dua. "

AT hniav thiab AT hniav zaum nyob rau hauv lub pulley groove sib txawv. AT hniav dais ntawm nws lub taub hau cheeb tsam tiv thaiv qhov zawj; tus T hniav tsis. Lub pulley zawj profiles yog sib txawv.

Muab AT5 siv rau ntawm T5 pulley: tus hniav 2.5 hli tsis haum rau qhov zawj txiav rau 1.78 hli, yog li nws caij siab, zaum ntawm nws cov flanks, thiab lub taub hau kev sib cuag yeej tsis tshwm sim. Muab T5 siv rau ntawm AT5 rubey: cov hniav nqaim rattles hauv qhov loj me, muab cov lus rov qab thiab cuam tshuam kev thauj khoom ntawm txhua qhov kev koom tes.

Tib lub suab tsis yog tib txoj siv. Txuas qhov profile rau lub pulley.

Muab ob npaug -sab thiab coj txawv txawv

DT profile(ob npaug-sided, Table 1.4.3) - rau serpentine drives los yog qhov twg ob txoj siv tawv ntsej muag tsav:

HTD 5M profile timing pulley

Hniav qhov ntev phim ib qho -sab T profile; tsuas yog tag nrho qhov siab nce.

TK profile(notched V-qhia, Table 1.4.4) - rau conveying qhov twg txoj siv yuav tsum taug qab tom qab:

Cov lus qhia no yog notched es tsis tas mus li, uas tso cai rau ib tug tsawg kawg nkaus pulley txoj kab uas hla tshaj ib tug puv -profile wedge. Ib tug nruam wedge resists dabtsi yog khoov; notching cia nws flex nyob ib ncig ntawm me me pulleys.

Curvilinear thiab parabolic profiles

Tshaj li cov tsev neeg trapezoidal, roj hmab synchronous siv siv curvilinear profiles (HTD, hauv 3M, 5M, 8M thiab 14M pitches) thiab niaj hnub parabolic profiles (hauv 2 hli, 3 hli, 5 hli, 8 hli thiab 14 hli pitches). Daim ntawv tus hniav parabolic faib kev ntxhov siab ntau dua los ntawm cov hauv paus hniav ntau dua li daim ntawv semicircular HTD, uas yog lub hauv paus rau nws lub zog siab dua ntawm tib lub suab thiab qhov dav.

Peb yuav tsis hais tus lej parabolic-vim-HTD lub zog kom zoo dua ntawm no. Cov nuj nqis no yog los ntawm txoj siv tawv- cov neeg tsim khoom tsav tsheb tsim cov phau ntawv, thiab cov khoom catalogs peb ua haujlwm los ntawm kev txiav txim cov ntaub ntawv es tsis yog phau ntawv engineering. Yog tias koj xav tau qhov kev sib piv rau kev txiav txim siab tsim qauv, coj nws los ntawm cov chaw tsim khoom siv txoj siv tawv es tsis yog los ntawm cov chaw muag khoom blog - suav nrog peb.

Dab tsi peb tuaj yeem qhia rau koj yog sab rub: peb txiav HTD 3M, 5M, 8M thiab 14M, thiab cov khoom sib thooj parabolic, mus rau qhov zawj geometry tus siv txoj hlua khi qhia.

Siv elongation

Ib daim duab tsim nyog paub txog kev tsim kab axis: tso cai elongation rau AT5 profile hauv tus qauv ST qaum kev tsim kho yogε_ tso cai=0.47%.

Ntawm 2-meter axis, 0.47% yog 9.4 hli ntawm kev tso cai siv txoj hlua txuas ntxiv. Tias yog vim li cas txoj siv sia ntev -tsav axes xav tau ib qho kaw - voj txoj hauj lwm ntsuas los yog ib qho kev sib kis ntawm lub cev - txoj siv elongation nyob rau hauv qhov sib txawv load yog qhov yuam kev ntawm txoj hauj lwm tiag tiag, ywj siab ntawm cov hniav profile.

Xaiv

T profile- kev xa hluav taws xob dav dav, kev xa tawm, lub teeb pom kev, tus nqi -sensitive, dav dav.

AT profile- linear positioning axes, siab dua torque nyob rau tib lub suab, qhov twg cov hniav deflection nyob rau hauv load teeb meem, conveyor drives qhov chaw nto siab tiv thaiv kev txhawb nqa rail yog ib qho kev txhawj xeeb.

DT- ob lub ntsej muag yuav tsum tau tsav tsheb.

TK / UA- yuav tsum muaj kev taw qhia sab nraud.

FAQ

Kuv puas tuaj yeem haum AT5 siv ntawm T5 rubey?

Tsis yog. Tus hniav AT yog 40% dav dua thiab zaum sib txawv. Nws yuav tsis zaum hauv qhov zawj kom raug.

Puas yog AT ib txwm zoo dua T?

Zoo dua ntawm lub peev xwm thauj khoom thiab nruj, kim dua thiab tsawg dua cov khoom lag luam. Rau ib lub teeb loaded conveyor, T yog qhov kev xaiv tsim nyog.

Vim li cas T thiab AT muaj lub kaum sab xis sib txawv?

40℃rau T, 50℃rau AT. Lub kaum sab xis dav dua yog ib feem ntawm yuav ua li cas AT profile tau txais nws cov hauv paus hniav dav thiab nws cov cwj pwm sib txawv.

Qhov dav ntawm tus hniav hauv qab qhia kuv li cas?

Nws yog lub hauv paus dav, uas tswj lub zog shear. AT5 ntawm 3.62 hli tawm tsam T5 ntawm 2.65 hli yog qhov pom tseeb tshaj plaws ntawm qhov muaj peev xwm sib txawv.

Lub sijhawm siv sijhawm ntev npaum li cas tuaj yeem ncav cuag?

Tshaj tawm tso cai elongation rau AT5 hauv tus qauv ST qaum yog 0.47%. Tshaj qhov ntev axis no yog qhov tseem ceeb txaus los xav txog hauv kev tswj lub tswv yim.

Tianjin OuNaiDa Transmissions Technology manufactures lub sij hawm siv pulleys nyob rau hauv T, AT, HTD thiab nti profiles, nyob rau hauv txhuas thiab hlau, nrog taper bush los yog kev cai bore. Qhia rau peb txog txoj siv sia thiab qhov dav uas koj siv thiab peb yuav phim lub pulley zawj profile kom raug.
