Portal crane tseem hu ua gantry crane. Lub gantry crane feem ntau yog tsim los ntawm cylindrical log, tsis, thaiv nres, steel hlau hlua, nqa nuv, cab, reducer, casting pulley, casting nruas, lub cev muaj zog, hluav taws xob tswj cov khoom thiab lwm yam. Tam sim no cia peb tham txog cov kev paub dav dav txog lub lubrication ntawm lub reducer ntawm gantry crane.
Nyob rau hauv lub reducer rau gantry crane, lub lubrication ntawm iav nto yuav luag tiav los ntawm immersion nyob rau hauv lub lubricating roj txhaj rau hauv lub reducer vaj tse, vim hais tias lub zog ntawm gantry crane feem ntau muaj me me peripheral ceev.
Txhawm rau txo qis kev sib hloov ntawm cov iav ntawm lub gantry crane, yog li txhawm rau txwv kev tsim hluav taws xob ntawm lub reducer, nws raug nquahu tias qhov tob ntawm lub iav tso rau hauv cov roj lubricating yuav tsum tsis txhob ntau tshaj peb lub moduli. Thaum lub moduli loj dua 20cm thiab lub viscosity ntawm lub lubricating roj yog loj, qhov tob ntawm lub iav tog rau hauv cov roj tsuas yog yuav tsum tau sib npaug zos rau qhov siab ntawm lub iav. Tsuas yog cov iav qis qis uas tsis muaj ribs ntawm ob lub log yog tso cai rau tog rau hauv qhov tob dua
Nyob rau hauv ob-theem thiab peb-theem kab rov tav iav reducers, kab rov tav nto ntawm lub gantry crane lubricating roj yuav tsum tau kho kom cov iav hniav ntawm lub high-ceev iav yuav immersed nyob rau hauv lub lubricating roj.
Nyob rau hauv ntsug reducer ntawm portal crane, thaum txoj kev immersion nyob rau hauv cov roj yog xaiv rau lubrication, lub sab sauv thiab central zog yog lubricated los ntawm cov txaws ntawm lubricating roj. Lub lubricating pinion txhawb los ntawm tus neeg tua tsiaj ntawv phaj kuj tuaj yeem xaiv tau, uas tau muab tso rau ntawm lub rotating ncej thiab yog instigated rau tig los ntawm ib tug ntawm cov loj zog. Thaum nws yog hom rotary lubricating roj rau iav reducer, nws yog ib qho tsim nyog yuav tau xav txog qhov ceev ntawm lub voj voog, qhov nruab nrab kub ntawm cov huab cua nyob ib puag ncig thiab cov kev xaiv tso cai tshwj xeeb siab. Qhov kev tso cai ntawm caj npab siab muaj feem xyuam rau qhov tawv tawv ntawm cov hniav.
Yog li ntawd, thaum nws yog hom rotary lubricating roj rau gantry crane iav kis tau tus mob, lub peripheral ceev, nruab nrab kub ntawm ib puag ncig huab cua thiab nto hardness ntawm cov hniav tuaj yeem txiav txim siab. Rau ob-theem thiab peb-theem reducers, xaiv cov roj lubricating uas nws viscosity yog qhov nruab nrab viscosity ntawm cov roj lubricating xav tau rau lubricating txhua theem kis. Nyob rau hauv lub gantry crane iav reducer, thaum lub ambient cua kub yog 20 degree, kev khiav hauj lwm kub ntawm lub lubricating roj yuav tsum tsis txhob ntau tshaj 55 degree.
