Roinnt bealaí chun foirmeacha imthacaí a chomhshuí
The inner and outer rings of the end bearing are fixed in two directions and bear two-way axial force. The bearing at the other end is not fixed axially, allowing the heated expanded shaft to extend freely. Due to different types of bearings, "two-way fixed" and "floating" " The structure of the bearing is also different. Usually, the bearing subjected to the smaller radial force is fixed in both directions to bear the axial force and coordinate the service life of the two bearings; when there is no axial force on the shaft, the bearing subjected to the smaller radial force swims to make the swimming convenient. This positioning method is often used for the shaft with large span or the shaft with high working temperature. How should the bearing be positioned on the shaft and the chassis frame? In the shafting, there are During the operation of some shafts, due to the working load, environment, speed and other problems, the shafts will have thermal expansion and cold contraction in the axial and radial modes; some shafts also need to transfer the load force to the frame because they bear a large axial load. There are three common bearing positioning modes
Slí amháin a shocrú ag an dá cheann
Is é an modh suite seo ná go bhfuil fáinne istigh an imthacaí ceangailte ar an iris trí fheisteas trasnaíochta, agus go bhfuil an ghualainn seafta bactha, agus go bhfuil fáinne seachtrach an imthacaí bactha ag an gclúdach deireadh imthacaí. Cuireann na himthacaí ag an dá cheann faoi seach cosc ar ghluaiseacht aonbhealaigh an tseafta. D'fhonn cosc a chur ar an imthacaí a bheith greamaithe ag fadú teirmeach an seafta, tá bearna de 0.2 0.3mm idir an clúdach deireadh imthacaí agus aghaidh deiridh fáinne seachtrach an imthacaí don gathacha. iompar ; le haghaidh an imthacaí sá gathacha, tá bearna de 0.2 0.3mm idir an clúdach deireadh imthacaí agus an seafta Úsáidtear grúpa gaiscéid idir na suíocháin imthacaí chun imréiteach inmheánach an imthacaí a choigeartú. Tá an modh suite seo oiriúnach don seafta stub le chasmhóiminte tarchurtha beag agus teocht íseal oibre.
Dhá bhealach socraithe ag foirceann amháin agus ag snámh ag foirceann amháin

Tacaíocht ag an dá cheann
Nuair a bheidh péire giaranna cnámh scadán mogalra, tarlóidh gluaiseacht aiseach beag mar gheall ar earráidí déantúsaíochta agus suiteála. D'fhonn cosc a chur ar an bhfearas dul i bhfostú, is minic a dheartar an dá thacaíocht ar an seafta fearas cnámh scadán beag mar mhodh snámha, agus socraítear an dá thacaíocht ar an seafta fearas scadán. Nuair a bhíonn an t-iompar sleamhnáin ag tacú leis an seafta, tá an seafta suite go haiseach ag ghualainn an seafta. Nuair is gá foirceann amháin a shocrú, socraítear an dá thaobh den iris ag an deireadh seasta Gualainn nó collar, nó teaglaim imthacaí sleamhnáin gathacha agus imthacaí sleamhnáin sá.
