Taw qhia ntawm tus kheej-aligning pob bearings
Jul 06, 2022| Self-aligning pob bearings yog bearings nruab nrog spherical npas ntawm lub nplhaib puab ntawm ob raceways thiab lub nplhaib sab nrauv uas cov raceways yog kheej kheej.
Qhov chaw ntawm curvature ntawm lub nplhaib sab nrauv raceway nto yog zoo ib yam nrog rau qhov chaw ntawm cov kabmob, yog li nws muaj qhov ua haujlwm ntawm tus kheej raws li tus kheej-aligning pob bearing. Thaum cov ncej thiab vaj tse yog deflected, lawv tuaj yeem hloov kho tau yam tsis muaj kev txhawb nqa lub nra. Spherical roller bearings tuaj yeem tiv taus radial loads thiab axial loads hauv ob qho kev qhia. Loj radial load peev xwm, haum rau hnyav loads thiab shock loads. Sab hauv txoj kab uas hla ntawm lub nplhaib puab yog ib tug bearing nrog ib tug tapered bore, uas yuav tsum tau ncaj qha mounted. Los yog nruab nws ntawm lub cylindrical ncej siv lub tes tsho adapter thiab lub tes tsho dismantling. Cov tawb siv steel stamping tawb, polyamide ua tawb thiab tooj liab alloy tig tawb.
Tus kheej-aligning pob bearing muaj ob tug qauv ntawm cylindrical qhov thiab conical qhov, thiab cov khoom ntawm lub tawb yog steel phaj, hluavtaws resin, thiab lwm yam. Qhov yuam kev tshwm sim los ntawm kev tsis sib haum xeeb thiab cov ncej deflection, tab sis tus txheeb ze inclination ntawm sab hauv thiab sab nrauv rings yuav tsum tsis txhob ntau tshaj 3 degrees.
Nws muaj peev xwm dais loj radial load thiab kuj dais tej yam axial load. Lub nplhaib sab nrauv ntawm cov kabmob no yog kheej kheej, yog li nws muaj qhov ua tau zoo ntawm tus kheej. Thaum lub ncej yog khoov los yog tilted nyob rau hauv quab yuam, yog li ntawd tus txheeb ze inclination ntawm cov kab nruab nrab ntawm lub nplhaib puab thiab lub hauv paus kab ntawm lub nplhaib sab nraud tsis tshaj 1 degree mus rau 2.5 degree, cov kabmob tseem tuaj yeem ua haujlwm. .
Lub puab lub qhov ntawm tus kheej-aligning pob bearing muaj ob hom: cylindrical thiab conical. Lub taper ntawm lub conical bore yog 1:1 2 los yog 1:30. Txhawm rau txhim kho lub lubricating kev ua tau zoo ntawm cov kabmob, cov roj annular groove thiab peb lub qhov roj yog machined ntawm lub nplhaib sab nraud ntawm cov kabmob.
