Lub pob ntsia hlau yog dab tsi?
Ball screw is a rolling system, including screw, nut and a certain number of rolling elements. During the rolling process, the trajectory of the ball on the nut is determined by the nut holder.
Qhov zoo ntawm lub pob ntsia hlau: Lub pob ntsia hlau yob zoo li lub pob bearing. Cov pob uas muaj los yog ntau dua xov lem sab hauv. Kev siv dov kev tsis sib haum xeeb muab lub cev muaj txiaj ntsig hauv qab no.
Lub zog siab: cov lus tsa suab tig ua cov lus tsa suab nrog lub zog tshaj 90 feem pua; linear tsab ntawv tsa suab ua cov lus tsa suab nrog lub zog me ntsis ntawm 90 feem pua, cov qauv compact, me me pib torque, tsis tshua muaj hnav thiab siab reversibility.
Pob screws muaj cov yam ntxwv hauv qab no:
(1) Lub zog siab: Pob ntsia hlau tshuaj xyuas cov cuab yeej thiab cov cuab yeej tshuaj xyuas zoo kom ntseeg tau tias lub zog ntawm cov khoom mus txog ntau dua 90 feem pua
(2) Qhov kub thiab txias me me: Lub pob zoo tshaj plaws ntawm qhov zoo ntawm cov ntsia hlau ntsia hlau thiab lub pob nruj kom txo qis qhov tsis sib haum xeeb ntawm lub pob thiab qhov khiav;
(3) High precision: Cov ntsia hlau tsav khub ua rau cov cuab yeej tau txais qhov chaw siab tshaj plaws los ntawm txoj kev xws li qhov kub thiab txias me me thiab ua ntej- zawm qhov sib txawv.
Lub pob ntsia hlau yog tsim rau siab - nrawm thiab siab - lub sijhawm muaj tseeb. Nyob rau hauv txoj kev no, ob qhov kawg yog sib cais los ntawm ib khub ntawm bearings txwv lub axial thiab radial degrees ntawm kev ywj pheej, thiab lub load yog borne los ntawm ob pawg ntawm bearing khub. Nws tseem tuaj yeem ua rau cov kabmob sib txuas ntawm ob qho kawg tau txais qhov rov qab ua ntej, thiab tom qab ntawd ua qhov kev sib kis rigidity. Thaum cov kev xav tau ntawm qhov chaw siab siab, nws tseem tuaj yeem ua kom raug lub hom phiaj stroke nyiaj them raws li qhov xwm txheej quab yuam thiab thermal deformation qauv ntawm cov hlau lead ntsia hlau los txhim kho qhov tseeb ntawm qhov chaw. Qee lub sij hawm, qhov ruaj khov -taw hom tseem hu ua ib qho -sided ob lub laub-ob lub laub. Nyob rau hauv qhov tseeb, vim muaj nyob ntawm radial quab yuam, tsis tshua muaj ob thrust bearings li tas tas. Vim tias txoj kev no yog qhov nyuaj hauv cov qauv thiab nyuaj rau kev kho, nws feem ntau tsuas yog siv thaum qhov kev xav tau ntawm qhov siab.
