Nekoliko načina uobičajenog pozicioniranja oblika ležajeva
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
Jednosmjerno pričvršćivanje na oba kraja
Ova metoda pozicioniranja je da se unutarnji prsten ležaja pričvrsti na čahuru pomoću zahvata i blokira ramenom osovine, a vanjski prsten ležaja blokira završni poklopac ležaja. Ležajevi na oba kraja sprječavaju{{0}}jednosmjerno pomicanje osovine. Kako bi se spriječilo da se ležaj zaglavi toplinskim izduženjem osovine, postoji razmak od 0.2 0,3 mm između završnog poklopca ležaja i krajnjeg dijela vanjskog prstena ležaja za radijalni ležaj; za radijalni potisni ležaj, postoji razmak od 0,2 0,3 mm između završnog poklopca ležaja i osovine. Grupa brtvi između sjedišta ležaja koristi se za podešavanje unutarnjeg zazora ležaja. Ova metoda pozicioniranja prikladna je za osovinu s malim zakretnim momentom prijenosa i niskom radnom temperaturom.
Dvosmjerno fiksirano na jednom kraju i plivajuće na jednom kraju

The bearing at the other end is not fixed in the axial direction, allowing the heated and expanded shaft to extend freely. Due to the different types of bearings, they are "two-way fixed" and "swimming" "The structure of the bearing is also different.

Podrška na oba kraja
Kada se par zupčanika riblje kosti spoji, doći će do blagog aksijalnog pomaka zbog pogrešaka u proizvodnji i ugradnji. Kako bi se spriječilo zaglavljivanje zupčanika, dva oslonca na zupčaniku male riblje kosti često su dizajnirana kao način plivanja, a dva oslonca na osovini zupčanika riblje kosti su fiksirana. Kada je oslonac osovine klizni ležaj, osovina je postavljena aksijalno uz rame vratila. Kada je jedan kraj potrebno učvrstiti, obje strane čaure na fiksnom kraju su fiksirane Rame ili ovratnik, ili kombinacija radijalnog kliznog ležaja i potisnog kliznog ležaja.
