Več načinov skupnega pozicioniranja oblik ležajev
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
Enosmerna pritrditev na obeh koncih
Ta metoda pozicioniranja je, da je notranji obroč ležaja pritrjen na letev z vpetjem in blokiran z ramo gredi, zunanji obroč ležaja pa je blokiran s končnim pokrovom ležaja. Ležaji na obeh koncih preprečujejo{{0}}enosmerno premikanje gredi. Da preprečimo, da bi se ležaj zataknil zaradi toplotnega raztezanja gredi, je med končnim pokrovom ležaja in čelno ploskvijo zunanjega obroča ležaja razmak 0.2 0,3 mm za radialni ležaj; za radialni potisni ležaj je reža 0,2 0,3 mm med končnim pokrovom ležaja in gredjo. Skupina tesnil med sedeži ležaja se uporablja za nastavitev notranjega razmika ležaja. Ta način pozicioniranja je primeren za gred z majhnim navorom prenosa in nizko delovno temperaturo.
Dvosmerno pritrjeno na enem koncu in plavanje na enem koncu
The inner and outer rings of the bearing at one end are fixed in two directions and bear two-way axial force. 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. Usually, the bearing subject 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 subject 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.
Podpora na obeh koncih
Ko se par zobnikov ribje kosti zaplete, pride do rahlega aksialnega premika zaradi napak pri izdelavi in montaži. Da bi preprečili, da bi se orodje zataknilo, sta dva opora na zobni gredi z ribjo kostjo pogosto zasnovana kot plavalni način, obe podpori na zobni gredi ribje kosti pa sta pritrjeni. Ko je podpora gredi drsni ležaj, je gred nameščena aksialno z ramo gredi. Kadar je treba en konec pritrditi, sta obe strani leče na fiksnem koncu pritrjeni Ramo ali obroč ali kombinacija radialnega drsnega ležaja in potisnega drsnega ležaja.
