Mib shaft :Material yog 50Mn zoo carbon structural steel, nrog C cov ntsiab lus ntawm 0.48 mus rau 0.56%, Si cov ntsiab lus ntawm 0.17 mus rau 0.37%, Mn ntsiab lus xws li 0.7 mus rau 1.0%, S cov ntsiab lus xws li tsawg dua 0.035%, P cov ntsiab lus xws li Los ntawm tsawg dua 0.035%, thiab Cr cov ntsiab lus xws li tsawg dua 0.25 mus rau 0.30%, Ni cov ntsiab lus xws li tsawg dua 0.30%, thiab Cu cov ntsiab lus xws li tsawg dua 0.25%. tuaj yeem txhim kho cov ductility thiab plasticity ntawm cov khoom, xyuas kom txaus toughness thiab hnav tsis kam.Tom qab kev kho cua sov, 50Mn steel muaj lub zog siab thiab hardness, kev nkag tau zoo heev, txheej txheej tawv tawv, thiab cov pearlite zoo nkauj, thiab kev ua haujlwm zoo.
Cov qauv tsim rau lub ntsiab ncej yuav tsum muaj qhov tob ntawm 2 mus rau 7 mm ntawm hardening txheej thiab tempering hardness ntawm 50 mus rau 62 HRC.
Lub cev :Txhawm rau txhim kho qhov hnav tsis kam ntawm lubtrack roller's Lub cev, cov khoom siv yog 40Mn2 alloy structural steel, nrog C cov ntsiab lus xws li 0.37 txog 0.44%, Si cov ntsiab lus xws li 0.17 txog 0.37%, Mn cov ntsiab lus xws li 1.4 txog 1.8%, P cov ntsiab lus xws li tsawg dua 0.030%, thiab S cov ntsiab lus xws li los ntawm tsawg dua 0.030%.
Cov cov menyuam hauv qabLub cev yog molded nrog ib tug txheej txheem forging.Tom qab molding, lub log ntxhib lub cev yog tempered mus cuag ib tug hardness ntawm 26-32HRC kom muaj lub siab zog, plasticity, toughness, thiab tag nrho cov neeg kho tshuab kev ua tau zoo nyob rau hauv lub log lub cev.Lub log lub cev nto yog raug rau quenching kev kho mob kom lub hardness thiab hnav tsis kam ntawm lub log rail nto.The quenching hardness yog 50-58HRC, nrog ib tug tob ntawm 6-12 hli.Qhov no ua rau muaj qhov zoo sib xws ntawm txoj kev tsheb nqaj hlau nyuaj thiab cov saw txuas sib txuas hardness (48-58HRC).
foob:Qhov loj thiab qhov roughness ntawm lubO-ringyuav tsum ua raws li cov qauv tsim.Lub mating nto yuav tsum tau muab sib dhos, thiab yuav tsum tau ntxuav-up ntawm tej burrs thiab ntse npoo.
Floating foob roj hmab thiab O-nplhaibyuav tsum tau xaiv los ntawm high-zoo butyl roj hmab.Lub puab txoj kab uas hla, xov loj, elasticity, hardness (Shore), thiab nto tag yuav tsum tau ua raws li cov qauv.Ua ntej sib dhos, tag nrho cov khoom saum toj no yuav tsum tau kuaj xyuas thiab tsim nyog raws li cov qauv saum toj no ua ntej kev teeb tsa.
Gap :Lub clearance ntawm lub axle lub ntsiab axis thiab lub hub bearing ntawm lubcov menyuamlub cev yuav tsum yog 0.2-0.4 mm.Thaum tig, yuav tsum tsis txhob thaivteeb meemthiab sealing kev ua tau zoo, tsis muaj roj to.
Lubrication :Cov roj bearing hauv lubkhiav rollr Yuav tsum tau txhaj tshuaj siv cov roj twj tso kua mis.Thaum tsim nyog, cov roj viscosity ntawm lubricating roj yuav tsim nyog.Ua ntej txhaj cov roj bearing, lub lubricant uas tsis siv lawm yuav tsum tau ntws tawm.Tom qab ntawd, cov roj nplua nyeem tshiab yuav tsum muab ntxiv rau hauv cov roj ntsaws qhov kom txog thaum cov roj ntws tawm.Thaum txhaj cov roj lubricating, lub hub cap ntsia hlau yuav tsum tau muab tshem tawm, thiab cov roj kawg ntawm cov khoom siv roj yuav tsum tau nias rau ntawm lub xub pwg nyom hauv cov roj channel. Lub zog torque ntawm cov roj ntsaws yuav tsum tswj ntawm 157-255 Nm.
