Main tsav
Rau lub ntsiab tsav, qhov tseem ceeb tshaj plaws yog kev siv kaw-voj tswj synchronous lub cev muaj zog thiab asynchronous lub cev muaj zog. Lawv yog siv los ua ke cov motors thiab cov motors nyob rau hauv lub tshuab dhos, milling tshuab, sib tsoo tshuab, thiab machining chaw.
Kev siv ib txwm siv ntawm lub tshuab tsav-tsav spindle drives, feem ntau cua txias, yog ntau heev. Piv rau lub cev muaj zog spindles, nws yog suav hais tias yog ib qho kev daws teeb meem kev lag luam, coj mus rau hauv tus account tus nqi thib ob ntawm ob lub tshuab. Qhov nruab nrab hloov ntawm lub gearbox ua rau nws ua tau, ntawm ib sab, kom phim qhov ceev thiab lub zog rau lub machining yuav tsum tau, thiab ntawm qhov tod tes, lub gearbox generates undesired radial rog, suab nrov thiab nce hnav.
Lub tswv yim tsav spindle siv lub cev muaj zog nrog kev sib koom ua ke ntawm spindle yog tag nrho cov paub tab ntawm ib theem kev. Txij li thaum lub gearbox thiab clutch yuav raug tshem tawm, nyob rau hauv no tsav ib tug tag nrho centered swivel tsab ntawv tsa suab tsis muaj radial rog yuav ua tau tiav, uas yog cim los ntawm lub sij hawm ntev lub suab thiab tsawg hnav thiab yog tshwj xeeb tshaj yog haum rau high-power txiav kev khiav hauj lwm.
Tsim kom muaj lub zog siab zog tseem yog qhov nyuaj, xws li ib qho (planetary) kis tau tus mob yuav tsum tau ua ke ntawm lub ntsiab ncej, los yog lub cev muaj zog yuav tsum tau xaiv. Rau kev tiv thaiv kev saib xyuas thiab kev kho, kev soj ntsuam sensors sib xyaw ua ke ntawm cov ncej tam sim no tau tsim los ua tus qauv rau kev ntsuas cov ntaub ntawv tau, thaum txias nrog roj, cua lossis glycol yog qhov tseem ceeb!
Pub tsav
Pub tsav tuaj yeem pom tau los ntawm mechatronics lossis hydraulic system. Xaiv raws li qhov zoo thiab qhov tsis zoo ntawm kev sib txawv tshwj xeeb tsav technologies.
Tam sim no, feem ntau ntawm cov mechatronic feed drives hauv ntiaj teb no siv servo motors nrog lub pob ntsia hlau tsav los hloov cov lus tsa suab rau hauv cov lus tsa suab. Tsis zoo li cov tsav tseem ceeb, ntawm no, synchronous enclosed motors nyiam los ntawm qhov kev xav tau siab ntawm qhov chaw raug, synchronization thiab kev ua haujlwm zoo.
Vim nws qhov siab zoo li qub, qhov kev tsav tsheb no tuaj yeem siv rau hauv ntau qhov chaw thiab tau dhau los ua ib qho kev daws teeb meem. Txawm li cas los xij, hnav yog loj heev. Nyob ntawm qhov teeb meem ntawm kev teeb tsa thiab qhov loj ntawm lub torque yuav tsum tau tsim, lub servo lub cev muaj zog ncaj qha los yog los ntawm cov hniav profile Cov siv yog txuas nrog spindle.
Txawm hais tias lub hauv paus ntsiab lus ntawm hluav taws xob linear motors tau tsim nyob rau hauv lub xyoo pua 19th, lub tshuab no tsis tau pib siv rau cov cuab yeej siv tshuab kom txog rau thaum xyoo 1990. Lub sijhawm ntawd Rexroth tau nruab thawj cov cuab yeej siv tshuab nrog linear motors. Kev sib xyaw ua ke ntawm kev hnav-dawb, siab zog thiab siab zog ntawm qhov tsav no feem ntau txais tos. Nws yog li lav rau kev ua haujlwm tsis muaj teeb meem mus sij hawm ntev nrog kev ua haujlwm siab piv rau kev sib piv cov pob ntsia hlau nrog kev ntsuas qhov ntsuas tsis ncaj.
Ntawm qhov tod tes, qhov kev txwv ntawm kev siv yog nyob rau hauv lub peev xwm nqa ntawm tus tsav: yog li ntawd, rau lub sijhawm uas muaj siab txiav quab yuam, nws tseem tsis tuaj yeem tso tseg kev siv lub pob ntsia hlau tsav los yog cov kev daws teeb meem hydraulic. Ntawm qhov tod tes, nyob rau hauv kev sib raug zoo nrog rau lwm yam kev koom tes tshuab Cheebtsam, piv txwv li, lub siab tshaj plaws kev tso cai txav ceev ntawm cov ntaub thaiv npog txiav thiab damping kev ua tau zoo ntawm daim ntawv qhia swb kuj txwv kev siv cov tsav. Qhov zoo ntawm linear motor drive thev naus laus zis piv nrog cov nqi peev uas cuam tshuam tau tseem cuam tshuam rau thoob ntiaj teb kev ua tiav ntawm cov tshuab tsav no kom deb li deb.
Hom tsav no tsuas yog siv thaum qhov zoo ntawm hydraulic feed drive raug txiav txim siab. Feem ntau yog siv rau hauv qhov chaw me me, cov yam ntxwv muaj zog siab lossis lub sijhawm pub noj loj loj. Nws mus yam tsis tau hais tias rau hydraulic feed drives, qhov tseeb ntawm qhov ntsuas micron yuav tsum ua tau.
Daim ntawv thov tshwj xeeb ib txwm xav kom lub hydraulic linear tsav yuav tsum muaj peev xwm ua haujlwm ntev yam tsis muaj kev cuam tshuam thiab muaj lub neej ua haujlwm ntev dua li lub pob ntsia hlau tsav. Rau cov khoom siv hluav taws xob, lub zog sib thooj (torque thiab ceev) yuav tsum tau teeb tsa, thaum lub hydraulic tsav ncej tau txais lub zog ntawm qhov kev thov hauv cov kua accumulator, yog li lub zog hluav taws xob tuaj yeem raug txo los ntawm 80 feem pua.
