Linear guide rail accuracy grades are divided into (walking parallelism, the following takes the guide rail 100mm length as an example), ordinary grade (no mark/C) 5μm, high grade (H) 3μm, precision grade (P) 2μm, ultra-precision grade (SP) 1.5 μm, ultra-super precision (UP) 1μm
1 Raws li lub hom phiaj ntawm cov tshuab sib txawv. Muab lub slider preload. Feem ntau, ua ntej- compression muab faib ua tsis muaj pre- compression, nruab nrab pre- compression, thiab hnyav ua ntej- compression. Qhov ntau dua qhov preload, qhov zoo dua qhov rigidity.
Load: Feem ntau, thaum pib ntawm kev xaiv qauv, 1/3 ntawm qhov ntsuas dynamic load yog txiav txim siab raws li qhov txwv ntawm qhov tseeb load. Yog li ntawd, nws yog feem ntau ntxiv rau nruab nrab preload kom paub meej tias tsis muaj dab dej. Yog hais tias cov kev taw qhia rail yog siv nce thiab nqis, cov kev taw qhia rail ncaj qha ua lub luag haujlwm coj. Ntau npaum li cas cov zawv zawg thaiv qhov nce yog cuam tshuam nrog cov ntsia hlau lossis lwm hom kev sib kis tau siv, thiab tsis muaj dab tsi cuam tshuam nrog cov swb rail thiab zawv zawg thaiv.
2 Yeej muaj peb hom hom sib txawv. Feem ntau, qhov sib txawv, lub teeb preloading, thiab nruab nrab preloading muaj qhov sib txawv loj dua uas tuaj yeem cuam tshuam rau kev taug kev raug, kev thauj khoom nqa peev thiab rigidity ntawm cov kab ntawv qhia. Ntxiv mus, xaiv ib qho kev qhia tawm nrog kev tshem tawm tuaj yeem txo qhov kev vibration thiab cuam tshuam los ntawm kev sib txuas lus mus rau qee yam.
3. Thaum lub load yog loaded, lub slider yuav tsis tog ntau. Cov lus qhia meej yuav tsum yog elastic deformation. Yog tias koj xav hais ntau npaum li cas, tam sim no tsis muaj daim ntawv lo rau hauv cov ntaub ntawv qhia tawm, vim nws tuaj yeem tsis quav ntsej.
