Txhawm rau xaiv qhov zoo tshaj plaws hluav taws xob linear actuator rau koj daim ntawv thov tshwj xeeb, kev ntsuam xyuas qhov tseem ceeb ntawm qhov ntev - suav nrogload peev, stroke ntev, ceev, kev khiav hauj lwm ib puag ncig, thiab mounting txoj kev-yog qhov tseem ceeb. Los ntawm kev sib piv cov khoom lag luam kom raug rau cov kev xav tau, koj tuaj yeem zam qhov tsis muaj txiaj ntsig, ua haujlwm luv luv, lossis muaj kev nyab xeeb los ntawm kev xaiv tsis raug. Hauv qab no yog ib kauj ruam -los ntawm- kauj ruam qhia kev xaiv tus kws tshaj lij, tsim nyog rau ntau yam xwm txheej xws li kev lag luam, kev lag luam, thiab kev siv hauv tsev.
I. Qhia qhov tseem ceeb ntawm kev ua haujlwm tsis zoo (Lub hauv paus ntawm Kev Xaiv)
1. Lub peev xwm thauj khoom: Sib tw qhov kev xav tau tiag tiag
Xam qhov tseeb Load: Xav txog kev thauj khoom zoo li qub (piv txwv li, qhov hnyav ntawm cov khoom), dynamic load (xws li, inertial quab yuam thaum txav), thiab ntxiv tsis kam (xws li, kev sib txhuam, cua quab yuam). Nws raug nquahu kom xaiv tus qauv nrog akev ruaj ntseg yam ntawm 1.2 ~ 1.5 × qhov tseeb loadtiv thaiv kev puas tsuaj los ntawm overloading.
Piv txwv li: Smart tsev lifting rooj yuav tsum tau 50 ~ 100kg load peev; industrial robotic caj npab yuav xav tau 500 ~ 5000kg rau kev thawb cov haujlwm; Cov txaj kho mob yuav tsum ua kom haum rau tib neeg qhov hnyav thiab cov khoom hnyav (pom zoo siab dua lossis sib npaug li 200kg).
Distinguish Load Hom:
Tensile Load: Rau kev hloov khoom siv tensile, tsom mus rau tus actuator lub zog tensile;
Compressive Load: Rau kev thawb cov neeg kho tshuab txav, xyuas kom cov actuator tsis kam rau compressive deformation;
Combined Load: Rau cov ntawv thov uas muaj ob lub laub / rub thiab sab nraud, xaiv cov qauv nrog cov txheej txheem coj los yog muaj zog tiv thaiv -offset peev xwm (xws li, pob ntsia hlau hluav taws xob linear actuators).
2. Stroke Length: Precisely Match Movement Distance
Ntsuas Qhov Zoo Tshaj Plaws: Qhov kev ncua deb ntawm tus actuator lub reciprocating txav (los ntawm tag nrho retracted mus rau tag nrho ncua). Txuag 5 ~ 10mm ntawm cov hlab ntsha tsis txaus kom tsis txhob ua tsis tiav mus txog qhov chaw teev tseg vim qhov teeb meem kev teeb tsa.
Piv txwv li: me me ntse xauv yuav tsum tau 5 ~ 20mm stroke; ua liaj ua teb tsev cog khoom qhov rais qhib xav tau 500 ~ 1500mm; industrial ntau lawm kab hloov tuaj yeem hloov kho rau ntau dua 2000mm.
Nco ntsoov qhov kev sib raug zoo ntawm Stroke thiab Load: The maximum load of some actuators may decrease slightly with increasing stroke. For long-stroke scenarios (>1000mm), ua ntej ua qauv nrog siab -cov qauv nruj (xws li, trapezoidal ntsia hlau + hlau vaj tsev).
