Dab tsi yog qhov peev xwm tshaj ntawm mini linear qhia?
"Mini linear phau ntawv qhias raug ntsuas rau 100N dynamic load- ntau npaum li cas overload lawv ua tau tiag tiag? "Yog tias cov cuab yeej muaj kev cuam tshuam tam sim ntawd, cov kev taw qhia mini puas yuav poob tam sim ntawd?" Raws li cov tub ntxhais kis tau tus mob rau lub teeb yuag, compact daim ntaub ntawv, lub peev xwm overload ntawm mini linear guides (feem ntau yog xa mus rau micro guides nrog dav tsawg dua los yog sib npaug li 15mm thiab tshaj li 0 N dynamic load) Kev nyab xeeb kev ua haujlwm tsis txaus tuaj yeem ua rau muaj kev puas tsuaj rau cov kev taw qhia, kev sib tsoo, lossis kev puas tsuaj, ua rau cov khoom siv poob qis, Cov kab lus no tau tsim cov ntsiab lus tseem ceeb ntawm cov ntawv qhia mini linear overload muaj peev xwm hla qhov ntev, suav nrog cov ntsiab lus ntau dhau, kev ntsuas qhov cuam tshuam, thiab daim ntawv thov scenarios, ua raws li 8-kauj ruam kev lag luam kev lag luam.
Kauj Ruam 1: 8 Cov Lus Qhia Tseem Ceeb rau Mini Linear Guide Overload Capacity
Txhais lub peev xwm overload thiab tsim kom muaj nuj nqis metrics
Ua ntej, qhia meej cov ntsiab lus tseem ceeb thiab cov qauv kev lag luam ntawm kev muaj peev xwm dhau los kom tsis txhob muaj kev xav tsis zoo:
Lub ntsiab lus ntawm Overload Capacity:Qhov siab tshaj plaws ntawm cov ntawv qhia mini linear tuaj yeem tiv taus nyob rau hauv luv luv - lub sij hawm los yog cuam tshuam tam sim ntawd thaum tuav cov qauv kev ncaj ncees thiab zam kev puas tsuaj mus tas li.
