Pob Screw vs Lead Screw - Dab tsi yog qhov txawv

Cov cuab yeej siv hluav taws xob thiab cov cuab yeej kho mob cia siab raupob screwsthiab ua cov ntsia hlau kom ua tiav cov kab hluav taws xob tswj kev tswj hwm kev ruaj ntseg. Vim tias lawv zoo sib xws thiab sib tshooj hauv lawv daim ntawv thov, nws yooj yim kom tsis meej pem thaum lub sijhawm xaiv. Kab lus no yuav qhia meej meej txog kev ua haujlwm thiab cov yam ntxwv tseem ceeb ntawm ob qho tib si thiab muab cov lus qhia txog kev xaiv tswv yim.

Lub pob ntsia hlau hloov cov lus tsa suab mus rau hauv cov lus tsa suab los ntawm kev ncig cov pob ntawm cov ntsia hlau thiab cov txiv ntoo. Vim hais tias nws yuav tsum tau circulating pob bearings, pob ntsia hlau sib dhos yog feem ntau loj dua cov hlau lead ntsia hlau.
Rolling kev sib txhuam muab nws:
• Kev sib kis tau zoo heev
• Muaj peev xwm muab tso rau
• Kev tshem tawm cov teeb meem rov qab zoo
• Haum rau siab -ceev thiab siab - load tej yam kev mob

Thaum lub taub hau ntsia hlau ua haujlwm zoo ib yam li lub pob ntsia hlau, nws cov qauv yooj yim dua. Nws feem ntau siv trapezoidal threads (ACME), metric ACME, me me metric threads, thiab siab helix kaum threads. Tsis zoo li dov cov lus tsa suab ntawm lub pob ntsia hlau, cov ntsia hlau lead siv zawv zawg rau cov lus tsa suab.
Nws cov yam ntxwv muaj xws li:
• Tsis tshua muaj suab nrov thiab ua haujlwm du
• Tus nqi qis thiab cov qauv yooj yim
• Yuav tsum tu yam tsawg kawg nkaus los yog tsis xav tau lubrication
• Haum rau qis - mus rau - nruab nrab ceev thiab lub teeb - mus rau - nruab nrab load kis

Qhov tseem ceeb ntawm cov qauv sib txawv ntawm cov pob ntsia hlau thiab cov ntsia hlau lead - dov kev sib cuag piv rau kev sib cuag zawv zawg - ncaj qha txiav txim siab lawv cov kev ua tau zoo ntawm kev ua tau zoo, thauj khoom, ceev, raug, suab nrov, thiab kev saib xyuas.

Transmission Efficiency

Pob ntsia hlau tuaj yeem ua tiav cov txiaj ntsig txog li 90%, feem ntau yog vim qhov sib cuag ntawm cov pob ntawm cov ntsia hlau thiab cov txiv ntseej, txo qis kev sib txhuam thiab kev ua haujlwm poob. Nyob rau hauv sib piv, cov hlau lead screws yog zawv zawg kev sib txhuam cov qauv, ua kom muaj kev tiv thaiv tseem ceeb, nrog rau feem ntau lub zog poob los ntawm kev sib txhuam, uas ua rau tsis tshua muaj kev sib kis.

Load Capacity

Cov npas hauv lub pob ntsia hlau faib cov load hla ntau lub ntsiab lus sib cuag, txo qis kev ntxhov siab hauv zos thiab ua rau nws muaj zog dynamic load-cov kabmob muaj peev xwm. Lead screws concentrate lub load ntawm threaded zawv zawg nto; nyob rau hauv hnyav loads, kev sib txhuam thiab hnav nce sai, ua rau lawv haum rau nruab nrab mus rau lub teeb loads thiab discontinuous load scenarios.

Kev Ua Haujlwm Ceev

Vim tias cov pob ntsia hlau muaj kev sib txhuam qis thiab ua kom muaj cua sov tsawg, lawv tuaj yeem ua tau siab - nrawm nrawm. Lead screws lawv tus kheej ua kom muaj cua sov ntau vim zawv zawg kev sib txhuam; nyob rau hauv siab -ceev tej yam kev mob ceev, cov cua kub no tuaj yeem ua rau muaj kev puas tsuaj ntxov rau cov ntsia hlau txhuas, cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.

Qhov tseeb thiab Backlash

Pob ntsia hlau tuaj yeem tshem tawm qhov rov qab los ntawm kev hloov kho ua ntej, tswj xyuas qhov chaw siab. Lead screws xav tau qee qhov kev tshem tawm rau kev zawm zawv zawg, qhov tseeb muaj qhov rov qab loj dua, ua rau muaj qhov tsis zoo dua qub piv rau cov pob ntsia hlau.

Suab nrov thiab Smoothness

Thaum lub sijhawm ua haujlwm siab - nrawm, qhov siab - nrawm nrawm thiab cuam tshuam ntawm cov pob hauv lub pob ntsia hlau tawm tsam cov xa rov qab ua rau lub suab nrov nrov. Lead screws siv zawv zawg txhuam nrog tus kheej -lubricating ceev ua haujlwm ntsiag to.

Kev Kho Kom Zoo

Pob screws yuav tsum tau lubrication tsis tu ncua los tiv thaiv kev sib cuag ncaj qha ntawm cov pob thiab cov kev sib tw, uas tuaj yeem ua rau hnav, muaj suab nrov, thiab txo qhov raug. Lead screws, tshwj xeeb tshaj yog cov uas nruab nrog tus kheej -lubricating polymer txiv ntseej, tuaj yeem ua haujlwm nyob rau hauv kev saib xyuas tsis tshua muaj neeg, ua rau lawv tsim nyog rau cov khoom siv kaw lossis tsis tshua muaj kev tswj xyuas.

Nqi

Pob screws tuaj yeem ua haujlwm ntawm kev kub ceev thiab muaj qhov raug siab, nrog rau ntau yam kev ntsuas kev ua tau zoo tshaj li cov hlau lead screws, inevitably xav tau cov nqi tsim khoom ntau dua. Tsis tas li ntawd, pob screws yuav tsum tau lubrication thiab tu, ua rau cov nqi kho mob ntau dua.

Hauv ntau daim ntawv thov, pob screws feem ntau muab cov txiaj ntsig zoo ntawm cov hlau lead. Txawm li cas los xij, rau qee qhov kev siv yooj yim, cov ntsia hlau txhuas yog qhov kev xaiv zoo rau kev tswj hwm tus nqi.

Pob ntsia hlau zoo li muaj qhov zoo dua me ntsis ntawm cov ntsia hlau txhuas hauv kev sib kis tau zoo, qhov tseeb, kev khiav hauj lwm ceev, thiab lub peev xwm thauj khoom. Txawm li cas los xij, qhov zoo ntawm cov hlau lead screws, xws li kev ua haujlwm ntsiag to thiab kev saib xyuas qis dua, yuav tsum xav txog. Ob leeg tuaj yeem txhawb nqa lawv lub zog hauv cov ntawv thov tsim nyog. Qhov tseem ceeb yog xaiv cov ntsia hlau uas tsim nyog tshaj plaws raws li cov ntawv thov tshwj xeeb, tso cai rau txhua yam khoom siv kom muaj txiaj ntsig zoo tshaj plaws hauv nws cheeb tsam ntawm kev txawj ntse.
