Mpira wakuya wamtundu wa 2, mpira wakuya wa groove wokhala ndi chidindo

Mipira yokhazikika yakuya yakuya yokhala ndi zisindikizo ndi zolembera zosindikizira RS (NSK imayitana DDU, chisindikizo cha mbali imodzi) ndi 2RS (zisindikizo za mbali ziwiri) ndi zitsulo zosamata RZ (NSK imayitana VV, chisindikizo chimodzi) ) Ndi mtundu wa 2RZ.Magwiridwe ake, kudzaza mafuta, ndi kugwiritsa ntchito ndizofanana ndi zomwe zimakhala ndi zovundikira fumbi, kupatulapo kuti pali kusiyana kwakukulu pakati pa chivundikiro cha fumbi ndi mphete yamkati, ndi kusiyana pakati pa milomo yosindikiza ndi mphete yamkati ya zomwe si- kukhudzana chisindikizo ndi chaching'ono.Palibe kusiyana pakati pa milomo yosindikiza ndi mphete yamkati ya mphete yosindikizira, ndipo kusindikiza kwake kuli bwino, koma kugundana kwawonjezeka.

Mpira wakuya wamtundu wa 3, mpira wakuya wa groove wokhala ndi posungira ndi mphete yosungira

Khodi yokhazikika ya ma berelo a mpira wakuya ndi positi ndi N, ndipo positi khodi ya ma berelo a mpira wakuya wokhala ndi poyimitsa poyambira ndi mphete yoyimitsa ndi HR.Kuphatikiza apo, pali mitundu yosiyanasiyana yamapangidwe monga ZN ndi ZNR.Kuphatikiza pa ntchito yosunga mpira wakuya wa groove wokhala ndi mphete yosungira, mphete yosungira imathanso kuchepetsa kusuntha kwa axial kwa kubera, kuchepetsa kapangidwe ka mpando wonyamula ndikuchepetsa kukula kwake.Nthawi zambiri, imagwiritsidwa ntchito pazinthu zogwirira ntchito zokhala ndi axial ang'onoang'ono, monga magalimoto ndi mathirakitala.

Mpira wakuya wamtundu wa 4, mpira wakuya wakuya wokhala ndi kusiyana kwa mpira

Standard mpira grooved deep poyambira mpira mayendedwe awiri awiri awiri mndandanda wa 200 ndi 300. Pali mipata pa mkati ndi kunja mphete mbali imodzi, kotero kuti mipira yambiri akhoza yonyamulidwa kuchokera izo, kuonjezera mphamvu zake radial katundu.Komabe, chifukwa cha mphamvu yaing'ono ya axial katundu, sangathe kuthamanga kwambiri.Ngati pali axial katundu wamkulu, iyenera kugwiritsidwa ntchito limodzi ndi ma bearings a mpira wakuya.

Mpira wakuya wamtundu wa 5, mizere iwiri yakuzama mpira wokhala ndi mpira

Mipira yokhazikika ya mizere iwiri yakuya ndi 4200A ndi 4300A.Ma bere amtundu wa A alibe mipata ya mpira.

Mpira wakuya wamtundu wa 6, mzere umodzi wakuzama mpira wokhala ndi mpira

Mzere umodzi wozama wa mpira wokhala ndi torque yocheperako ndi yoyenera kuzungulira kothamanga, phokoso lotsika komanso kugwedezeka pang'ono.Kuphatikiza pa mtundu wotseguka, palinso mayendedwe okhala ndi chivundikiro cha fumbi lachitsulo, mphete za mphira, ndi khola losindikizidwa lachitsulo.
