Slewing kev txhawb nqa yog ib hom tshiab ntawm cov khoom siv tshuab hloov maj mam nyob rau hauv 40 xyoo tas los, uas tau siv thoob plaws ntiaj teb. Slewing kev txhawb nqa yog tsuas yog tsim ntawm cov nplhaib sab hauv thiab sab nraud thiab dov lub cev. Nyob rau tam sim no, cov kabmob slewing tsim nyob rau hauv peb lub tebchaws yog cov thev naus laus zis thiab kev ua haujlwm siab, tab sis kev saib xyuas ntawm cov menyuam txaj nyob hauv kev peacetime, tshwj xeeb tshaj yog cov phom slewing hauv ntauwd cranes, yuav tsum tau them rau. Yuav ua li cas tswj cov menyuam cov dej dag hauv qhov ntauwd crane? Nov yog cov lus qhia ntxaws ntxaws rau koj.
Slewing bearings nyob rau hauv lub installation ntawm bearings yuav tsum them nyiaj tshwj xeeb rau, cov kabmob yuav tsum muaj kev nruj zoo, thiab saum npoo yuav tsum tau ceev cia. Thaum sib sau ua ke kev txhawb nqa slewing, kev kho kev ntxhov siab yuav tsum tau nqa tawm, thiaj li ua kom txo qhov deformation ntawm kev them nyiaj yug me nyuam, thiab xyuam xim rau kev tu lub npoo. Thaum siv, peb yuav tsum xyuam xim rau qhov hloov ntawm lub suab thiab rotary tsis kam lub sijhawm. Yog tias muaj teeb meem, peb yuav tsum kuaj xyuas lawv raws sijhawm.
Slewing bearing tsis tuaj yeem nqa lossis khaws cia ntsug. Nws yuav tsum ua haujlwm tav toj kom tsis txhob deformation ntawm slewing cov kabmob. Thaum txhim kho kev txhawb nqa slewing, lub pob tw yuav tsum nruj thiab cov meshing ntawm lub tseev siv yuav tsum raug kuaj xyuas, vim tias lub meshing yuav tsum ua raws li cov teeb tsa raug ntawm lub zog. Txhawm rau kom paub tseeb tias kev ua haujlwm ntawm lub ntsia liaj qhov rooj, nws yog qhov tsim nyog kom tsis txhob muaj lub zog txaus ua ntej rub tawm ntawm lub ntsia liaj qhov rooj, thiab kuaj xyuas lub zog ua ntej ntawm cov ntsia liaj qhov rooj hauv lub sijhawm tom qab kev txhawb nqa ua haujlwm rau 100 lossis 500 teev.
Thaum zawm cov noob txiv, nws tsim nyog ntxiv cov roj lubricating, thiab siv cov ntsia hlau ntsaws ntsaws ntsaws kom ceev cov txiv ntoo ua kom zoo thiab sib npaug hauv cov kev coj ua rau ntau lub sijhawm. Yog tias qhov kev hloov pauv ntawm cov kabmob yog idling nrov, nws yuav yog tias tus hniav kub nyob hauv ntauwd crane tau tawg, yog li nws yuav tsum tau kho kom ncav sijhawm.
