Kab tawm tsav
Cov tsoos "rotating lub cev muaj zog + pob ntsia hlau" pub kis tau tus mob hom ntawm lub tshuab cuab yeej yog ib qho nyuaj rau ua ib tug breakthrough nyob rau hauv lub feed speed, acceleration, ceev positioning raug thiab lwm yam vim hais tias ntawm cov kev txwv ntawm nws tus kheej qauv. Nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ultra-siab ceev txiav thiab ultra precision machining ntawm servo kev ua tau zoo ntawm lub tshuab cuab yeej pub system. Linear lub cev muaj zog ncaj qha hloov hluav taws xob hluav taws xob mus rau hauv cov lus tsa suab tshuab hluav taws xob yam tsis muaj kev sib kis ntawm cov tshuab hloov pauv nruab nrab. Cov qauv siv hluav taws xob muaj qhov zoo ntawm qhov pib loj, kev sib kis siab nruj, cov lus teb ceev ceev, qhov tseeb ntawm qhov chaw siab, tsis muaj kev txwv tsis pub ntev, thiab lwm yam. Nyob rau hauv cov khoom noj ntawm cov cuab yeej siv tshuab, qhov sib txawv loj tshaj plaws ntawm kev tsav ncaj qha ntawm lub cev muaj zog thiab kev sib kis. ntawm thawj rotating lub cev muaj zog yog tias cov neeg kho tshuab kev sib txuas ntawm lub cev muaj zog mus rau qhov chaw ua haujlwm (carriage) raug tshem tawm, thiab qhov ntev ntawm cov khoom siv sib kis ntawm cov cuab yeej siv tshuab yog luv rau xoom. Yog li ntawd, hom kev sib kis no tseem hu ua "zero transmission". Nws yog precisely vim hais tias ntawm no "zero kis tau tus mob" hom uas tus thawj rotating lub cev muaj zog tsav hom tsis tuaj yeem ua tiav qhov kev ua tau zoo thiab qhov zoo.
1. Kev kub ceev teb
Vim tias qee qhov kev sib kis ntawm cov khoom siv tshuab (xws li cov ntsia hlau lead) nrog lub sijhawm teb loj tas li raug tso tseg ncaj qha rau hauv lub kaw lus, cov lus teb zoo ntawm tag nrho cov kaw-voj tswj qhov system tau txhim kho zoo heev, thiab cov lus teb yog qhov rhiab heev thiab ceev.
2. Precision
Lub linear tsav system tshem tawm cov kis tau tus mob clearance thiab yuam kev tshwm sim los ntawm cov neeg kho tshuab mechanisms xws li txhuas ntsia hlau, thiab txo qhov kev mus txog qhovtwg yuam kev tshwm sim los ntawm lub lag ntawm lub kis tau tus mob thaum lub sij hawm interpolation. Los ntawm kev tawm tswv yim tswj ntawm txoj haujlwm nrhiav pom, qhov tseeb ntawm qhov chaw ntawm lub tshuab cuab yeej tuaj yeem txhim kho tau zoo.
3. High dynamic rigidity vim "tsav ncaj qha", nws zam lub suab lag tshwm sim tshwm sim los ntawm elastic deformation, kev sib txhuam thiab hnav ntawm qhov nruab nrab kis tau tus mob thiab qhov thim rov qab clearance thaum pib, hloov ceev thiab thim rov qab, thiab tseem txhim kho nws txoj kev sib kis nruj. .
