Gearbox bearing: tiv thaiv kev sib txhuam hauv kev sib kis

Gearbox bearing (gearbox bearing) - ib feem ntawm lub gearbox ntawm cov khoom siv tsheb;ib tug dov bearing ntawm ib tug tsim los yog lwm yam, ua raws li kev txhawb nqa rau lub shafts thiab lub zog ntawm lub gearbox.

Nyob ntawm nws hom, tus naj npawb ntawm lub zog, txoj kev xa tawm torque ntawm cov ntsiab lus thiab cov qauv tsim, los ntawm 4 mus rau 12 lossis ntau dua bearings ntawm ntau hom tuaj yeem siv rau hauv lub gearbox.Bearings daws tau ntau yam teeb meem:

● Kev ua haujlwm ntawm kev txhawb nqa rau txhua tus lossis tsuas yog ib tus neeg shafts (feem ntau - ob qhov kev txhawb nqa rau txhua lub shafts, hauv qee lub thawv ntawv yooj yim lossis ntau txoj hauv kev - ib qho kev txhawb nqa rau lub hauv paus ncej, peb qhov kev txhawb nqa rau cov ncej thib ob, thiab lwm yam.) ;
● Ua raws li kev txhawb nqa rau cov iav mounted ntawm cov ncej thib ob (hauv cov khoom siv nrog cov sib txuas sib txuas thiab cov iav dawb-rotating ntawm cov ncej thib ob);
● Kev txo qis ntawm kev sib txhuam quab yuam hauv cov ncej thiab cov iav txhawb nqa (txo ntawm lub zog poob hauv kev sib kis, txo cov cua sov ntawm nws qhov chaw).

Kev siv cov bearings ua kom muaj kev txhim kho kom raug ntawm cov khoom txav ntawm lub gearbox thiab txo cov kev sib txhuam quab yuam uas tshwm sim ntawm cov khoom no.Cov xwm txheej thiab cov yam ntxwv ntawm cov bearings txiav txim siab qhov kev ua haujlwm ntawm lub gearbox, nws muaj peev xwm ua rau ib txwm xa tawm thiab hloov lub zog, thiab feem ntau ua kom muaj kev tswj hwm ntawm lub tsheb.Yog li ntawd, hnav thiab tsis zoo bearings yuav tsum tau hloov, thiab nyob rau hauv thiaj li yuav xaiv txoj cai ntawm cov khoom no, nws yog tsim nyog los to taub lawv tsim, hom thiab applicability.

Hom, tsim thiab yam ntxwv ntawm gearbox bearings

Nyob rau hauv tsheb, tsheb laij teb thiab lwm yam thauj gearboxes, txheem dov bearings ntawm ob peb hom tseem ceeb yog siv:

● Ib kab radial thiab angular contact balls;
● Pob ob kab angular hu;
● Ib-kab radial rollers;
● Roller conical ib kab;
● Roller koob ib kab thiab ob kab.

Txhua yam ntawm cov bearings muaj nws tus yam ntxwv thiab siv tau nyob rau hauv gearboxes.

Ib kab radial pob.Feem ntau cov kabmob uas tuaj yeem siv los ua kev txhawb nqa rau txhua qhov gearbox shafts.Raws li txoj cai, nws muaj ob lub nplhaib, ntawm qhov uas muaj ib kab ntawm cov pob hlau hauv qhov sib cais.Qee lub sij hawm cov npas tau npog nrog cov hlau lossis cov nplhaib yas los tiv thaiv kom tsis txhob muaj roj nplua nyeem.Cov kabmob ntawm hom no ua haujlwm zoo tshaj plaws ntawm cov thawv me me ntawm cov tsheb thiab cov maus taus, tab sis qee zaum lawv kuj pom muaj nyob rau ntawm qee qhov ntawm cov thawv ntim khoom.

Ib kab angular contact balls.Cov kabmob no feem ntau pom cov loads radial thiab axial, lawv feem ntau yog siv los ua kev txhawb nqa tom qab ntawm thawj thiab theem nrab shafts, uas thaum lub sijhawm ua haujlwm ntawm lub gearbox tuaj yeem raug thauj mus los ntawm cov axis (vim lub zog ntawm synchronizers thiab lawv qhov tseem ceeb. hauv cov tshuaj).Structurely, lub angular contact bearing zoo ib yam li cov kabmob radial, tab sis nws cov nplhaib tau nres uas tiv thaiv cov qauv ntawm kev sib tsoo hauv axial loads.

Pob ob-kab angular thrust.Cov kabmob ntawm hom no muaj kev tiv thaiv ntau dua rau kev thauj khoom siab, yog li lawv feem ntau yog siv los ua kev txhawb nqa rov qab rau thawj zaug thiab qee zaum nruab nrab ncej.Los ntawm kev tsim, cov kabmob no zoo ib yam li cov kabmob ib leeg, tab sis lawv siv cov nplhaib dav nrog cov chaw nres tsheb rau cov khoom.

Roller ib-kab radial.Cov kabmob no tuaj yeem ua haujlwm nyob rau hauv kev thauj khoom ntau dua li cov kabmob pob, yog li lawv tau siv los ua kev txhawb nqa rau txhua lub shafts hauv lub gearbox ntawm cov khoom siv tsheb - tsheb thauj khoom, tsheb laij teb, cov cuab yeej tshwj xeeb, cov tshuab ua liaj ua teb, thiab lwm yam. Raws li kev tsim qauv, bearings ntawm hom no zoo ib yam li pob bearings. , tab sis lawv siv cov chais ua cov ntsiab lus dov - lub tog raj kheej luv, ua ke nrog lub tawb, sandwiched ntawm cov nplhaib nrog cov npoo sab hauv.

Roller conical ib kab thiab ob kab.Bearings ntawm hom no feem ntau pom tau hais tias ob qho tib si radial thiab axial loads, thaum lawv muaj peev xwm tiv taus ntau dua li pob bearings.Xws li cov kabmob feem ntau yog siv los ua kev txhawb nqa nram qab thiab sab pem hauv ntej ntawm tag nrho cov shafts, ob-kab tapered bearings yog siv nyob rau hauv cov kev txhawb nqa rear ntawm cov thawj thiab thib ob shafts.Tus tsim ntawm no bearing siv tapered rollers, uas yog ntsia nruab nrab ntawm ob lub nplhaib nrog beveled puab nto.

Roller koob ib kab thiab ob kab.Cov kabmob ntawm hom no, vim lawv tsim, muaj qhov loj me me nrog kev ua haujlwm siab rau radial loads - qhov no yog ua tiav los ntawm kev siv me me-inch rollers (kab koob) raws li lub cev ntawm kev sib hloov, thiab qee zaum ntxiv los ntawm kev tso tseg rings thiab / lossis tawb.Feem ntau, rab koob bearings yog siv los ua cov iav txhawb nqa ntawm cov ncej thib ob, raws li kev txhawb nqa ncej thib ob (thaum nws cov ntiv taw nyob rau ntawm qhov kawg ntawm cov khoom siv nkag), tsawg dua li cov khoom txhawb nqa.
