Thaum lub excavator muaj suab nrov txawv txav thaum nws tig, yog tias muaj suab nrov nyob rau hauv ib txoj hauj lwm thaum lub sij hawm tag nrho cov kiv puag ncig, nws yuav tsum tau sim.Xav txog seb lub pinion iav thiab lub nplhaib loj iav puas muaj cov hniav tawg.Nyob rau tib lub sijhawm, cov hniav tawg ntawm lub nplhaib loj ntawm lub excavator kuj yog qhov teeb meem tshwm sim.Cov hniav tawg feem ntau tshwm sim nyob rau sab sauv ib nrab ntawm cov hniav dav kev taw qhia, thiab cov pob txha tawg cuam tshuam rau sab saum toj kawg ntawm cov hniav thiab tsim ib lub kaum sab xis ntawm 45 ° ~ 60 °.Txawm tias tag nrho cov hniav ntog, qhov tawg yog tshwm sim los ntawm kev nthuav dav ntawm sab saum toj mus rau hauv qab.

Xuzhou XZWD tau ua haujlwm hnyav los nrhiav kev daws teeb meem ntawm cov hniav tawg hauv slewing bearings rau excavators.Txoj kev npaj tshwj xeeb tau muab faib ua cov txheej txheem hauv qab no:

1. Xyuas kom meej tias sab clearance ntawm lub zog loj thiab me me tsis tsawg dua 0.06X modulus.

Rau 20-tuj excavator, lub module ntawm slewing bearing yog 10 modules, thiab cov hniav sab clearance ntawm lub loj thiab me zog yog tsis tsawg tshaj li 0.6 hli.

Hauv kev lag luam excavator spare xeem, vim tias cov neeg siv khoom tsis tau them nyiaj ntau rau cov hniav sab nraud thaum lub zog loj thiab me me, cov hniav tawg ntawm cov hniav tseem siab, yog li peb tshaj tawm cov kev sib raug zoo ntawm cov hniav tawg thiab cov hniav sab clearance. thiab cia lawv nkag siab txog kev tswj xyuas cov hniav sab nraud.Tsis yog, cov hniav tawg ntawm cov kabmob slewing yog kev zam.

Tom qab ntau xyoo ntawm kev tshaj tawm, cov hniav tawg ntawm lub nplhaib slewing tau nqis los ntawm 6% dhau los mus txog 5%.

2. 37 ° oblique iav slewing kev txhawb nqa.Cov iav ib feem ntawm qhov chaw uas tsis yog-installation ntawm lub slewing nplhaib iav yog hloov los ntawm tag nrho cov hniav dav mus rau ib tug chamfer ntawm 37 °, thiab lub nplhaib slewing yuav tsum Artificially txiav tawm ib feem uas feem ntau lov, yog li ntawd lub extrusion quab yuam tsis tau. concentrated thaum lub pinion iav hloov nyob rau hauv lub Upper ib feem ntawm cov hniav dav, yog li ntawd lub iav ib feem ntawm lub nplhaib slewing yuav tsis tsim extrusion kab nrib pleb nyob rau hauv thaum ntxov lub sij hawm ntawm kev siv, uas yuav zoo ncua qhov teeb meem ntawm cov hniav tawg thaum ntxov ntawm slewing. nplhaib iav.

Los ntawm qhov kev txhim kho no, tom qab ob xyoos ntawm kev txheeb cais, cov hniav tawg nrog cov kabmob slewing no tau nqis los ntawm yav dhau los 5% mus txog 4%.

3. Rotating kev txhawb nqa ntawm cov iav nrog maj mam hardness.Txij li thaum cov hniav tawg ntawm lub nplhaib slewing yog tshwm sim los ntawm extrusion, yuav ua li cas tiv thaiv extrusion ntawm loj thiab me zog yog lub ntsiab lus tseem ceeb.Thaum lub iav raug rau induction hardening, qhov cua sov ntawm lub iav yog muab faib ua peb ntu: ib qho nyuaj cheeb tsam, qhov chaw hloov pauv thiab thaj chaw mos.Lub hardness ntawm lub hardness yog HRC5056, thiab hardness ntawm cov mos mos cheeb tsam yog quenched thiab tempered hardness ntawm cov hlau matrix.

Nyob rau hauv txoj kev no, thaum lub zog loj thiab me me yog meshed thiab nyem, qhov muag muag ntawm qhov kawg saum npoo yuav raug nyem thiab deformed.

Tsis squeezing tawm.Tom qab ib xyoos ntawm cov ntaub ntawv txheeb cais, tsis muaj qhov tshwm sim ntawm cov hniav tawg nrog qhov slewing bearing, uas daws cov teeb meem ntawm cov hniav tawg tau zoo heev.
