Hauv kev tsim khoom thiab kev ua cov casters, kev ua raws li cov kev cai lij choj yog qhov tseem ceeb hauv kev ua kom cov khoom zoo thiab txo qhov feem pua ntawm cov khoom tsis zoo. Txij li qhov tsos mus rau kev sib dhos, los ntawm caster round runout mus rau overload peev xwm, txhua qhov txuas ntawm tus qauv kev cai lij choj yog qhov tseem ceeb. Hauv tsab ntawv no, peb yuav sau cov kev cai lij choj ua ntej kev tsim khoom thiab kev ua cov casters, txhawm rau muab cov ntaub ntawv siv tau rau kev txhim kho cov khoom zoo.
I. Cov kev cai tshwj xeeb ntawm qhov tsos
1. Kev tswj qhov tsis zoo ntawm cov khoom: txhua qhov khoom yuav tsum tsis muaj qhov tsis zoo uas cuam tshuam rau kev siv, xws li tawg, deformation thiab lwm yam. Qhov saum npoo ntawm cov khoom hlau yuav tsum ua cov txheej txheem tiv thaiv xeb, xws li txau xim tiv thaiv xeb lossis electroplating kho kom tiv thaiv xeb thiab xeb.
2. Kev sib npaug ntawm xim: qhov chaw ntawm cov khoom yuav tsum sib npaug xim, tsis muaj qhov sib txawv ntawm xim lossis cov pob kom ntseeg tau tias qhov zoo nkauj ntawm cov khoom.
Qhov thib ob, kev sib dhos ua ke cov kev cai
1. Kev ywj pheej ntawm cov khoom tig: cov casters, brackets thiab lwm yam khoom tig yuav tsum tig tau yooj yim, tsis muaj stagnation thiab loosening phenomenon, kom ntseeg tau tias cov khoom tuaj yeem txav mus los tau zoo hauv cov txheej txheem ntawm kev siv.
2. Kev ruaj khov ntawm lub rooj sib dhos caster: lub rooj sib dhos caster yuav tsum ruaj khov thiab txhim khu kev qha, thiab lub qag yuav tsum tsis txhob tig nrog lub caster kom tiv thaiv nws kom tsis txhob poob lossis puas tsuaj thaum mus ncig.
4. Kev ntseeg siab ntawm lub cuab yeej nres: Rau cov neeg tsav tsheb uas muaj lub cuab yeej nres, lub cuab yeej nres yuav tsum ntseeg tau kom ntseeg tau tias kev txav mus los ntawm cov neeg tsav tsheb tuaj yeem nres sai thiab zoo thaum xav tau.
5. Kev tswj qhov chaw ntawm lub kauj tsheb: qhov chaw ntawm lub kauj tsheb yuav tsum nyob nruab nrab ntawm 0.1mm-0.2mm kom ntseeg tau tias qhov yooj ywm thiab ruaj khov ntawm lub kauj tsheb.
6. Kev ua raws li qhov loj me: qhov loj me ntawm cov casters yuav tsum ua raws li GBT cov qauv kom ntseeg tau tias cov khoom muaj ntau yam thiab sib pauv tau.
Qhov thib peb, cov kev cai ntawm kev khiav ntawm lub caster
Qhov kev kam rau ntawm qhov khiav tawm ntawm lub caster yog ib qho ntawm cov ntsuas tseem ceeb los ntsuas qhov zoo ntawm lub caster. Qhov kev kam rau ntawm qhov khiav tawm ntawm lub ntsej muag kawg yuav tsum tau tswj hwm hauv 1.0% ntawm lub log txoj kab uas hla D, thiab qhov kev kam rau ntawm qhov khiav tawm ntawm lub radial yuav tsum tau tswj hwm hauv 0.5% ntawm lub log txoj kab uas hla D. Qhov no yuav ua kom cov casters nyob rau hauv qhov zoo thaum lub sijhawm tig. Qhov no tuaj yeem ua kom lub log caster nyob rau hauv cov txheej txheem tig kom du, txo qhov kev co thiab suab nrov.
Plaub, kev cai lij choj txog kev ua haujlwm ntau dhau
Tom qab kuaj xyuas qhov overload, qhov seem deformation ntawm lub log txoj kab uas hla D ntawm lub caster yuav tsum ua tau raws li tus qauv teev tseg. Qhov kev xav tau no tuaj yeem ua kom tus caster tseem tuaj yeem tswj tau qhov kev ua tau zoo ruaj khov thaum raug qee qhov overload, kom tsis txhob muaj kev puas tsuaj lossis kev ua tsis tiav los ntawm kev overload.
V. Cov kev cai tswjfwm kev ua haujlwm tsis zoo li qub
Tom qab qhov kev sim ntawm hydrostatic compression tsis kam, tus caster yuav tsum tswj tau qhov kev hloov pauv zoo thiab lub qag ruaj khov. Cov kev cai tshwj xeeb suav nrog: tsis muaj stagnation thiab loosening ntawm cov khoom tig; tsis muaj kev tig ntawm lub qag, thiab tsis muaj deformation cuam tshuam rau kev tig ntawm tus caster. Qhov no tuaj yeem ua kom ntseeg tau tias tus caster tseem tuaj yeem tswj tau qhov kev ua tau zoo ruaj khov thaum dais lub zog static.
Rau, qhov yuav tsum tau ua kom taug kev tau zoo
Nyob rau hauv cov xwm txheej xeem, tus caster yuav tsum ua tau raws li cov kev cai hauv qab no tom qab hla 500 qhov teeb meem ntawm lub tshuab xeem taug kev: lub log tsheb tsis muaj kab nrib pleb, spalling lossis kev hnav ntau dhau hauv zos; tsis muaj kev puas tsuaj tsis zoo thiab kev hloov pauv tas mus li uas cuam tshuam rau kev siv cov khoom caster; lub bearing (lub tes tsho qag) tig ib txwm tsis muaj qhov tshwm sim stagnation lossis loosening. Qhov kev xav tau no tuaj yeem ua piv txwv cov xwm txheej nyuaj hauv qhov xwm txheej siv tiag tiag los sim qhov ruaj khov thiab kev ntseeg tau ntawm casters.
Hauv kev xaus lus, cov kev cai ua ntej tsim thiab ua cov casters npog ntau yam xws li qhov tsos, sib dhos, caster puag ncig runout, overload peev xwm, hydrostatic siab tsis kam thiab taug kev ua tau zoo. Tsuas yog ua raws li cov kev cai no rau kev tsim khoom thiab ua tiav, peb tuaj yeem ua kom ntseeg tau tias qhov zoo thiab kev ua tau zoo ntawm casters ua tau raws li cov qauv. Tib lub sijhawm, ua raws li GBT tus qauv kuj tseem tuaj yeem txhim kho qhov versatility thiab interchangeability ntawm casters, coj kev paub zoo dua rau tus neeg siv.
