Thaum lub excavator muaj suab nrov txawv txawv thaum nws tau sib hloov, yog tias muaj suab nrov hauv qee txoj haujlwm thaum lub sijhawm tag nrho, nws yuav tsum raug kuaj. Txiav txim siab seb puas yog Pinion Pinion thiab lub ntsej muag loj lub ntsej muag tau tawg cov hniav. Nyob rau tib lub sijhawm, hniav tawg ntawm cov nplhaib loj ntawm cov excavator tseem yog qhov teeb meem feem ntau. Hniav pob txha lov feem ntau tshwm sim nyob rau sab qaum ib nrab ntawm tus hniav dav, thiab cov pob txha nqaj qaum ntawm cov hniav thiab cov ces kaum ntawm 45 ° ~ 60 °. Txawm hais tias tag nrho cov hniav ntog tawm, cov tawg yog tshwm sim los ntawm kev nthuav dav los ntawm sab saum toj mus rau hauv qab.

Xuzhou Xzwd tau ua haujlwm nyuaj los nrhiav kev daws teeb meem rau qhov teeb meem ntawm cov hniav tawg hauv slewing bearings rau excavators. Cov phiaj xwm tshwj xeeb tau muab faib ua cov txheej txheem hauv qab no:

1. Nco ntsoov tias qhov kev tshem tawm sab nraud ntawm cov loj thiab me me lub zog tsis tsawg tshaj li 0.06x modulus.

Rau 20-tuj excavator, cov qauv ntawm cov kabmob slewing yog 10 modules, thiab tus hniav sab cas ntawm cov loj thiab me me tsis tsawg tshaj 0.6mm.

Nyob rau hauv lub excavator spare xeem ua lag luam, vim tias cov neeg siv khoom tsis them rau cov hniav sib npaug thaum muaj kev tswj hniav tawg thiab cia lawv nkag siab tswj cov hniav sab. Tsis yog, cov hniav tawg ntawm cov kabmob slewing yog qhov tsis pom kev.

Tom qab ob peb xyoos ntawm kev tshaj tawm, tus hniav sib tsoo ntawm lub nplhaib ntxim hlub tau poob los ntawm 6% txog li 5%.

2. 37 ° Oblique Iav Slewing kev txhawb nqa. Lub iav ntu ntawm cov chaw tsis muaj chaw ntawm cov ntiv nplhaib sib tsoo yuav tsis muaj kev sib tw ntawm lub ntsej muag uas feem ntau yuav tsis muaj kev sib tsoo, yog li ntawd cov kab mob pinferrated, yog li ntawd cov kab mob pinful ntawm 37 °, yog li ntawd lub iav sib tsoo yuav tsis muaj kev tiv thaiv cov hniav tawg, yog li ntawd cov teeb meem thaum ntxov ntawm kev siv, uas tuaj yeem ncua sijhawm qhov teeb meem ntawm cov hniav tawg thaum ntxov ntawm lub sweing nplhaib iav.

Los ntawm kev txhim kho no, tom qab ob xyoos ntawm kev txheeb cais, cov hniav tawg nrog cov kabmob ntaj no tau nqis los ntawm 5% txog li 4%.

3. Kev them nyiaj yug ntawm lub zog nrog maj mam hardness. Txij li thaum lub nplhaib tawg ntawm lub nplhaib shroving yog mob los ntawm extrusion, yuav ua li cas tiv thaiv extrusion, me zog yog qhov tseem ceeb. Thaum lub iav yog raug rau induction hardening, ntu cua sov ntawm lub iav tau muab faib ua peb ntu nyuaj, thaj chaw hloov chaw thiab thaj chaw mos. Lub hardness ntawm thaj chaw nyuaj yog hrc5056, thiab lub hardness ntawm thaj chaw mos yog qhov kev txiav txim siab thiab npau taws ntawm cov hlau matrix.

Nyob rau hauv txoj kev no, thaum loj thiab me me thiab squeezed thiab nyem, qhov muag muag ntawm sab sauv kawg yuav squeezed thiab deformed.

Tsis muaj nyem tawm. Tom qab ib xyoos ntawm cov ntaub ntawv txheeb cais, tsis muaj cov hniav sib txig sib luag nrog cov kabmob no, uas daws qhov teeb meem ntawm cov hniav tawg zoo heev.
