Linear Pob Bearings
Linear pob bearings, los yog pob bearings, muaj spherical dov cov ntsiab lus (xws li, steel pob). Lawv muaj kev sib txhuam qis, kev ua haujlwm ntev dua, thiab qhov tseeb siab. Lawv yog hom nrov tshaj plaws ntawm dov linear bearings. Lub spherical geometry tso cai rau lawv siv nyob rau hauv ntau txoj kab bearing designs.
Linear Bearings nrog Cylindrical Rolling Elements
Linear bearings tuaj yeem muaj cylindrically zoo li dov cov ntsiab lus. Lawv muaj peev xwm thauj khoom ntau dua, rigidity, thiab poob siab thiab cuam tshuam tsis zoo dua li pob bearings. Txawm li cas los xij, lawv muaj kev sib txhuam ntau dua vim qhov chaw sib cuag loj dua, thiab lawv kuj muaj siab rhiab heev rau misalignments.
Koob Linear Bearings
Needle linear bearings kuj muaj cylindrical rollers hu ua koob uas muaj qhov ntev-rau-inch piv ntawm 3: 1 thiab 10: 1. Lawv muaj kev nruj dua thiab muaj peev xwm thauj khoom ntau dua li cov pob lossis cov kabmob cylindrical vim tias cov khoom thauj tau muab faib rau ntau dua ntawm cov menyuam me. Qhov me me ntawm cov menyuam yaus ua rau qhov chaw sib cuag thiab txo qhov deformation.
