Yuav txhais li cas "precision" rau linear guideway?

Precision ntawm linear rail system yog ib lub tswv yim zoo, peb tuaj yeem paub txog nws los ntawm peb yam hauv qab no: taug kev sib luag, qhov siab sib txawv hauv cov khub thiab qhov dav sib txawv hauv cov khub.

Taug kev parallelism yog hais txog qhov tsis sib xws ntawm cov blocks thiab rail datum dav hlau thaum linear bearing blocks ua haujlwm ntawm qhov ntev ntawm cov ntsia hlau thaum cov kab qhia kev coj tus kheej tau kho ntawm lub dav hlau datum nrog lub ntsia liaj qhov rooj.
Qhov siab sib txawv hauv cov khub xa mus rau qhov siab tshaj plaws thiab qhov siab tsawg kawg nkaus qhov ntev ntawm cov kab ntawv qhia cov blocks uas tau ua ke tib lub dav hlau datum.

Qhov dav sib txawv hauv cov khub xa mus rau qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov dav tsawg kawg nkaus ntawm txhua kab qhia kev thaiv thiab cov kab ntawv qhia kev tsheb ciav hlau datum dav hlau uas tau teeb tsa ntawm ib qho kev qhia kev tsheb ciav hlau.

Yog li qhov tseeb ntawm cov kab ntawv qhia yog qhov txawv ntawm tus nqi ntawm ntau qhov ntsuas: qhov loj me ntawm qhov siab H, qhov siab sib txawv hauv cov khub yog qhov siab H, qhov ntev ntawm qhov dav W, qhov dav sib txawv hauv ob peb qhov dav W, kev taug kev parallelism ntawm sab saud. ntawm cov kab swb thaiv mus rau qhov chaw qis ntawm cov swb tsheb ciav hlau, kev taug kev parallelism ntawm sab saum npoo ntawm swb thaiv mus rau sab saum npoo ntawm cov swb rail, thiab cov kab ncaj nraim ntawm qhov ntev ntawm cov kab ntawv qhia tsheb ciav hlau.

Noj cov kab qhia kev tsheb ciav hlau 1000mm ua piv txwv, qhov tseeb ntawm PYG linear phau ntawv qhia yog tib yam nrog HIWIN, uas tau muab faib ua C chav kawm zoo tib yam 25μm, qib siab H class 12μm, precision P chav kawm 9μm, ultra-precision SP chav kawm 6μm, ultra -precision UP chav kawm 3μm.

Class C~P linear guides ntawm PYG tuaj yeem ua tau raws li cov cuab yeej siv tshuab zoo tib yam, thiab chav kawm SP thiab UP linear qhia yog qhov tsim nyog rau kev tshawb fawb thiab thev naus laus zis thiab cov cuab yeej siv. Tsis tas li ntawd, los ntawm daim ntawv thov taw tes ntawm view, qhov precision ntawm linear qhia kuj txiav txim siab los ntawm cov khoom rigidity, preloading qib thiab lwm yam.
