Cov qauv thiab kev faib tawm ntawm cov spherical plain bearings

Cov qauv ntawm lub spherical Cov kabmob tiaj tiaj yooj yim dua li ntawm cov kabmob dov. Nws feem ntau muaj ib lub nplhaib sab hauv nrog lub ntsej muag kheej kheej sab nraud thiab lub nplhaib sab nraud nrog lub ntsej muag kheej kheej sab hauv.

Feem ntau nws yog siv rau kev txav qeeb qeeb (piv txwv li, kev txav kaum sab xis). Vim yog lub voj voog ntawm qhov chaw swb, nws kuj tseem tuaj yeem ua qhov kev txav mus los (piv txwv li, kev txav mus los tus kheej) hauv qee lub kaum sab xis. Nws tseem tuaj yeem ua haujlwm li qub thaum lub ncej txhawb nqa thiab lub plhaub ntawm lub ncej tsis sib npaug ntau. Lub voj voog tus kheej Cov kabmob tiaj tus siv rau hauv kev lag luam xws li kev txuag dej thiab cov tshuab ua haujlwm.

Cov kabmob kheej kheej siv dav hauv kev lag luam xws li kev tsim kho hydraulic cylinders, forging thiab nias cov cuab yeej, kev tsim kho tshuab, cov khoom siv tsis siv neeg, lub tshuab nqus dej hauv tsheb, thiab cov tshuab hydraulic. Cov kabmob kheej kheej yog cov kabmob kheej kheej swb. Hom yooj yim yog tsim los ntawm lub nplhaib sab hauv thiab sab nraud nrog lub ntsej muag sib txuas zawv zawg.

Nta:

Cov kabmob kheej kheej muaj peev xwm thauj khoom loj thiab tiv taus kev cuam tshuam, thiab lawv kuj muaj cov yam ntxwv tiv taus xeb, tiv taus hnav, sib dhos tus kheej, lubrication zoo lossis lubrication tus kheej yam tsis muaj kuab paug los ntawm cov kuab paug lubricating. Txawm tias lawv tau teeb tsa tsis sib xws, lawv tseem tuaj yeem ua haujlwm li qub. Yog li ntawd, cov kabmob kheej kheej siv dav hauv kev txav oscillating qeeb qeeb, kev txav tilting thiab kev txav tig.

Pawg:

Muab faib ua pawg raws li qhov kev taw qhia ntawm lub nra uas lawv tuaj yeem dais lossis lub kaum sab xis ntawm lub kaum sab xis: (Kev faib tawm ntawm cov kabmob kheej kheej: radial spherical plain bearings, angular contact spherical plain bearings, thrust spherical plain bearings, rod end spherical plain bearings)

1. Cov kabmob radial spherical plain bearings: Lawv siv los tiv taus cov khoom thauj radial, nrog rau cov ces kaum sib cuag nominal txij li 0 degrees txog 45 degrees.

a: Radial contact spherical plain bearing: Ib qho spherical plain bearing nrog lub kaum sab xis ntawm 0 degrees, tsim nyog rau kev tiv taus cov khoom thauj radial. Txawm li cas los xij, nws kuj tseem tuaj yeem tiv taus cov khoom thauj axial me me thaum dais cov khoom thauj radial.

b: Angular contact radial spherical plain bearing: Ib qho radial spherical plain bearing nrog lub kaum sab xis nominal loj dua 0 degrees tab sis tsawg dua lossis sib npaug rau 45 degrees, muaj peev xwm tiv taus cov khoom thauj radial thiab axial ua ke tib lub sijhawm.

2. Thrust spherical plain bearings: Lawv siv los tiv taus cov axial loads, nrog rau lub kaum sab xis nominal ntau dua 45 degrees txog 90 degrees

a: Axial contact thrust plain bearing: Ib qho thrust plain bearing nrog lub kaum sab xis ntawm 90 degrees, tsim nyog rau kev tiv taus cov axial ntshiab.

b: Angular contact thrust spherical plain bearings: Thrust spherical plain bearings nrog lub nominal contact Angle loj dua 45 degrees tab sis tsawg dua 90 degrees yog qhov tsim nyog rau kev tiv taus cov axial loads, tab sis kuj tuaj yeem tiv taus cov khoom sib xyaw ua ke (hauv qhov no, tus nqi radial load yuav tsum tsis pub tshaj 0.5 npaug ntawm axial load).

Lub spherical plain bearing yog dab tsi?

Cov kabmob tau muab faib ua cov kabmob dov thiab cov kabmob swb. Cov kabmob dov feem ntau tig los ntawm qhov chaw sib cuag lossis kab sib cuag ntawm cov khoom dov sab hauv (cov khoom dov suav nrog cov pob hlau, lub menyuams, koob dov, thiab lwm yam). Cov bearings no nrog cov ntsiab lus dov hu ua rolling bearings. Sliding bearings, ntawm qhov tod tes, yog cov bearings uas tig los ntawm kev sib txhuam swb. Lawv muaj cov yam ntxwv ntawm kev sib txhuam hlau tawm tsam hlau thiab kev sib txhuam hlau tawm tsam cov ntaub ntawv hnav-resistant, thiab lwm yam. Yog li ntawd, sliding bearings tsis muaj cov ntsiab lus dov.

Cov kabmob kheej kheej yog cov sawv cev ib txwm muaj. Lawv lub npe tag nrho yog radial spherical plain ball bearings lossis radial spherical plain sliding bearings. Peb tsuas yog hu lawv ua spherical plain bearings. Lawv cov qauv yooj yim dua li cov rolling bearings. Lawv muaj ib lub nplhaib sab nraud nrog lub ntsej muag kheej kheej sab hauv thiab ib lub nplhaib sab hauv nrog lub ntsej muag kheej kheej sab nraud ntsia ua ke. Thaum lub sijhawm txav mus los, lawv tuaj yeem tig thiab co ntawm txhua lub kaum sab xis me me thiab feem ntau yog siv rau kev ua haujlwm qeeb.

Kev faib tawm ntawm cov kabmob kheej kheej:

Tom qab ntau xyoo ntawm kev txhim kho, cov kabmob spherical plain bearings tau hloov zuj zus mus rau ntau hom raws li ntau yam kev siv ib puag ncig, tshwj xeeb tshaj yog suav nrog:

Cov bearings radial spherical plain bearings, rod end spherical plain bearings, thrust angular contact spherical plain bearings. Cov hom no kuj muab faib ua maintenance spherical plain bearings thiab maintenance-free spherical plain bearings. Maintenance-free spherical plain bearings yog cov bearings uas muaj lubricating self-lubricating.

Cov lej hom thiab lub ntsiab lus ntawm cov spherical plain bearings:

Cov lej hom ntawm cov kabmob tiaj tus kheej yooj yim heev. Nws muaj cov lej hom pem hauv ntej, cov lej nruab nrab thiab cov lej hloov pauv tom qab. Yog tias muaj hom, nws tuaj yeem cim ua ntej cov lej hom pem hauv ntej.

Piv txwv li:

GE50ES-2RS

GE: Hom code, qhia txog GE series hom spherical plain bearings

50: Nominal sab hauv txoj kab uas hla (tsis yog qhov tseeb sab hauv txoj kab uas hla, vim tseem muaj kev kam rau siab)

E: Nws qhia tau hais tias muaj qhov axial slit qhib rau ntawm lub nplhaib sab nraud ntawm cov kabmob (qhov axial slit txhais tau hais tias muaj qhov slit raws li qhov kev taw qhia ntawm tus ncej).

S: Qhia tau hais tias lub spherical plain bearing muaj ib lub roj groove thiab ib lub roj qhov.

RS: Nws qhia tau hais tias cov kabmob muaj ib lub nplhaib sib khi, yog li 2RS txhais tau tias nws muaj cov nplhaib sib khi ntawm ob sab

GE60DO-2RS

GE: Raws li tau hais los saum toj no, hom code qhia txog GE series hom spherical plain bearings

60: Nominal sab hauv txoj kab uas hla (tsis yog qhov tseeb sab hauv txoj kab uas hla thiab nrog kev kam rau siab)

UA: Ib yam li ES, nws qhia tau hais tias muaj qhov axial slit qhib rau ntawm lub nplhaib sab nraud ntawm cov kabmob, thiab ob lub nplhaib sab hauv thiab sab nraud muaj cov roj grooves thiab cov roj qhov.

RS: Cov kabmob muaj ib lub nplhaib sib khi, yog li 2RS txhais tau tias nws muaj cov nplhaib sib khi ntawm ob sab

GE40UK-2RS

GE: Hom code, qhia txog GE series ntawm cov spherical plain bearings

40: Nominal sab hauv txoj kab uas hla (tsis qhia tias qhov tseeb sab hauv txoj kab uas hla muaj kev kam rau siab)

UK: Ib yam li E, nws qhia tau hais tias qhov axial slit tau qhib rau ntawm lub nplhaib sab nraud ntawm cov kabmob, tab sis nws yog cov kabmob spherical plain uas tsis tas yuav saib xyuas (self-lubricating spherical plain bearing).

RS: Nws yog hais txog ib lub bearing nrog ib lub nplhaib sealing rau ib sab, thiab 2RS txhais tau tias nws muaj cov nplhaib sealing rau ob sab.
