Bulldozer bearings bitundu bya makanika ebikulu ebikozesebwa okuwanirira ebitundu ebikyukakyuka, okukendeeza ku kusikagana, n’okutambuza emigugu. Zitera okubaamu empeta ey’omunda (nga efuumuuka n’ekikondo), empeta ey’ebweru (nga efuumuuka n’ennyumba), elementi eziyiringisibwa (emipira gy’ekyuma, ebizingulula n’ebirala), n’ekiyumba (ekyawulamu ebintu ebiyiringisibwa). Ekintu kyayo okusinga kibeera kya kaboni chromium chromium steel (nga GCR15), ekirimu obugumu obw’amaanyi (Rolling element hardness kituuka ku HRC60-65), okwambala okuziyiza, n’okuziyiza obukoowu oluvannyuma lw’okulongoosebwa mu bbugumu. Kiyinza okukwatagana n’embeera enkambwe ey’okukola eya bulooka nga omugugu omuzito, okukankana, enfuufu, n’ebirala.Okusinziira ku ngeri y’okusikagana, bbeeri za bulooka eziyinza okugabanyizibwamu bbeeri eziyiringisibwa (ezikendeeza okusikagana okuyita mu bintu ebiyiringisibwa era nga zisinga kukozesebwa) n’okusereka (ebiwagirwa okusika omuguwa okusereba, ng’ebisaka). Mu byo, ebivuga ebiyiringisibwa bifuuse ebitundu ebikulu ebizimbulukuka ebya bulooka olw’omugerageranyo gwazo omutono ogw’okusikagana n’okukyusakyusa sipiidi ey’amaanyi.1. Okuwagira ebitundu ebikyukakyukaOkuwa radial ne axial positioning for shaft components (nga drive shafts, gear shafts) okukakasa okukola okunywevu kw’ebitundu ebikyukakyuka (gears, sprockets, etc.) ku predetermined trajectories, okwewala okusika oba okutomeragana okuleetebwa offset.Reduce frictions losses2. Kyuusa okusika omuguwa okusereba kw’ebitundu ebizimbulukuka mu kusikagana okuyiringisibwa (oba okusereba okutono okusika) okuyita mu bintu ebiyiringisibwa (oba ebifo ebisereka), okukendeeza ku kufiirwa kw’amaanyi mu kiseera ky’okutambuza amaanyi, n’okulongoosa obulungi bw’okutambuza.Okutwala n’okutambuza emigugu3. Weesibe omugugu gwa radial (nga self weight of the shaft, radial force of gear meshing) n’omugugu gwa axial (nga empalirizo ya axial ekolebwa thrust ya bulldozer shovel) mu kiseera kya bulldozer operation, era zitambuza omugugu ku kisusunku oba fuleemu okwewala obutereevu okukyukakyuka kw’omubiri gw’ekikondo wansi w’amaanyi.
Enkola za bulijjo ez'okukozesa .
When bulldozers are operating (such as pushing hard soil or climbing slopes), the bearings need to withstand huge impact loads (such as the instantaneous load of the driving wheel bearings reaching more than 10 tons), so it is necessary to choose bearings with high bearing coefficients (such as tapered roller bearings and self-aligning roller bearings), and improve their impact resistance by thickening the ring and strengthening the Ebintu ebikozesebwa mu kuzimba.
2. Anti obucaafu n’okusiba .
Embeera y’okukoleramu erimu enfuufu era erimu ebitosi, era bbeeri zeetaaga okukozesebwa awamu n’ebitundu ebisiba (nga ebisiba amafuta n’ebibikka enfuufu):
Ebitundu ebirabika (nga track drive wheel bearings) byetaaga ebisiba amafuta g'emimwa ebiri n'ebibikka enfuufu okuziyiza ebitoomi n'omusenyu okuyingira mu luguudo lw'empaka (Impurities can cause "abrasive wear" of the bearings, ekikendeeza ku bulamu bwabyo ebitundu ebisukka mu 50%);
Bearing eziri munda mu ggiya bbokisi zeesigamye ku kusiiga woyiro wa ggiya n’okusiba, era kyetaagisa okukakasa nti ggiya bbokisi tekulukuta.
3. Okusiiga n’okusaasaanya ebbugumu .
Bbeeri ezitambula ku sipiidi ey’amaanyi (nga bbeeri za gearbox spindle) zeetaaga okusiiga okukakasibwa ne woyiro wa ggiya (okufuyira okuyita mu mikutu gya woyiro) okuggyamu ebbugumu ery’okusikagana (okwewala okulemererwa kwa giriisi olw’ebbugumu eringi);
Low speed heavy-Barings z’omulimu (nga bbeeri za baketi pin roller) zeetaaga okusiiga bulijjo ne giriisi (omulundi gumu buli ssaawa 200) okukola firimu ya woyiro n’okukendeeza ku kusikagana.
·Ekizibu: Okulemererwa nga bukyali ku bbeeri za nnamuziga eziwanirira eziva ku kukuba amayinja. Okugonjoola:
okwettanira ennyiriri ssatu eza 'tapered roller bearings' (nga zirina okweyongera kwa 50% mu mugugu-obusobozi bw'okusitula)
Okulongoosa enkola ya roller logarithmic curve (okugatta okugabanya situleesi) .
Upgrade lubricating grease to fully synthetic lithium based grease (drip point>260 diguli ) .
2. Embeera y’okuzimba enzizi:
·Okusomooza: Okulemererwa okusiba okuva ku kuyingira kw’amazzi/okusenya · Dizayini ey’obuyiiya:
Double Lip Oil Seal+Okusiba amazzi ga magineeti (Ekipimo ekiziyiza amazzi IP68)
Teeka emikutu gy’amazzi agakulukuta ku ntebe ya bbeeri (nga Design ya Caterpillar D6T)
3. Okukola mu bitundu ebya waggulu-obugulumivu:
·Pain point: Ebbugumu eri wansi erya -50℃C lireetera giriisi okukakanyala. Okuziyiza:
Pre filled low-Gisimu ya bbugumu eri bbeeri (akyayinza okukulukuta ku -60℃C) .
Londa ekyuma ekinyweza ennyo (charpy impact amaanyi agasinga oba agenkana 100J)
