Tus kheej-aligning pob bearings yog bearings nyob rau hauv uas spherical npas yog haum nruab nrab ntawm ib lub nplhaib puab nrog ob raceways thiab ib lub nplhaib sab nraud nrog spherical raceways.
Qhov nruab nrab ntawm curvature ntawm lub nplhaib sab nrauv raceway coincides nrog lub chaw bearing, yog li muaj tib tus kheej -aligning muaj nuj nqi raws li tus kheej -aligning pob bearings. Lawv tuaj yeem hloov kho thaum lub tog raj kheej lossis vaj tse deflection tshwm sim, tsis tas yuav nce cov kabmob. Tus kheej-aligning pob bearings tuaj yeem tiv taus radial loads thiab axial loads hauv ob qho tib si. Lawv muaj lub peev xwm loj radial load thiab haum rau hnyav -load thiab cuam tshuam-load daim ntawv thov. Cov kabmob uas muaj lub nplhaib puab sab hauv tuaj yeem txuas ncaj qha, lossis ntsia ntawm lub tog raj kheej siv lub tes tsho lossis lub tes tsho adapter. Cages muaj nyob rau hauv stamped steel, molded polyamide, thiab machined tooj dag alloy.
Tus kheej -aligning pob bearings muaj nyob rau hauv ob qho tib si cylindrical thiab tapered bore configurations, thiab tawb cov ntaub ntawv muaj xws li hlau thiab hluavtaws cob. Nws cov yam ntxwv muaj xws li ib tug kheej kheej kheej kheej nplhaib raceway, muab nws tus kheej -aligning zog los them rau qhov uas tsis ua los ntawm misalignment thiab ncej deflection. Txawm li cas los xij, tus txheeb ze qaij nruab nrab ntawm cov nplhaib sab hauv thiab sab nrauv yuav tsum tsis txhob siab tshaj 3 degrees.
Nws tuaj yeem tiv taus qhov loj radial loads thiab kuj muaj qee yam ntawm axial load. Vim tias txoj kev sib tw sab nrauv yog kheej kheej, hom kabmob no muaj tus kheej -aligning zog. Thaum cov ncej tau raug khoov lossis tilting, ua rau cov txheeb ze qaij nruab nrab ntawm lub nplhaib sab hauv thiab sab nraud ntawm qhov nruab nrab tsis pub tshaj 1℃txog 2.5 degree, cov kabmob tseem tuaj yeem ua haujlwm.
Tus kheej -aligning pob bearings muaj cylindrical lossis tapered puab bores. Taper ntawm tapered puab bore yog 1:12 lossis 1:30. Txhawm rau txhim kho lubrication, cov roj annular groove thiab peb lub qhov roj yog tshuab rau ntawm lub nplhaib sab nraud.
