Muaj ntau txoj hauv kev ntawm kev tso npe ntawm cov bearings
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
Ib txoj kev kho ntawm ob qhov kawg
Txoj kev tso npe no yog tias lub nplhaib sab hauv ntawm cov kabmob yog fastened rau ntawm phau ntawv xov xwm los ntawm kev cuam tshuam haum, thiab thaiv los ntawm lub xub pwg nyom, thiab lub nplhaib sab nraud ntawm cov kabmob yog thaiv los ntawm cov kabmob kawg. Cov bearings ntawm ob qho tib si xaus raws li tiv thaiv ib qho {{0}} txoj kev txav ntawm lub ncej. Txhawm rau tiv thaiv cov kabmob los ntawm kev daig los ntawm thermal elongation ntawm lub ncej, muaj qhov sib txawv ntawm 0.2 0.3mm ntawm cov kabmob kawg npog thiab lub ntsej muag kawg ntawm lub nplhaib sab nraud ntawm cov kabmob rau cov radial. bearing; rau lub radial thrust bearing, muaj qhov sib txawv ntawm 0.2 0.3mm ntawm cov kabmob kawg npog thiab cov ncej Ib pawg ntawm gaskets nruab nrab ntawm lub rooj zaum bearing yog siv los kho qhov kev tshem tawm sab hauv ntawm cov kabmob. Txoj kev muab tso rau no yog tsim rau cov ncej ncej nrog me me kis tau tus mob torque thiab qis ua haujlwm kub.
Ob txoj kev tsau ntawm ib kawg thiab ua luam dej ntawm ib kawg

Txhawb nqa ntawm ob qho kawg
Thaum ib khub ntawm herringbone gears mesh, me ntsis axial txav yuav tshwm sim vim kev tsim khoom thiab kev teeb tsa yuam kev. Txhawm rau tiv thaiv lub iav los ntawm kev daig, ob qho kev txhawb nqa ntawm lub me me herringbone iav ncej feem ntau yog tsim los ua luam dej, thiab ob qho kev txhawb nqa ntawm lub herringbone iav ncej yog tsau. Thaum kev txhawb nqa ntawm tus ncej yog zawv zawg bearing, lub ncej yog positioned axially los ntawm lub xub pwg nyom. Thaum ib kawg yuav tsum tau kho, ob sab ntawm phau ntawv journal ntawm qhov kawg yog tsau lub xub pwg los yog dab tshos, los yog kev sib xyaw ntawm radial zawv zawg bearing thiab thrust zawv zawg bearing.
