Cummins QSK Flange Coupling Kit - Torsional Vibration Damping Nrog Self-Centering Spline Adapter

 

Nyob rau hauv high-tso diesel xyaw tsav generators, compressors, los yog marine propellers, lub coupling ntawm lub crankshaft thiab cov khoom tsav yog deb tshaj li ib tug neeg kho tshuab connector. Nws ua raws li ib tugtorsional caij nplooj ntoos hlavuas cuam tshuam rau tag nrho rotating los ua ke lub ntuj zaus. Kev tsis sib haum xeeb hauv kev nruj lossis kev sib raug zoo tuaj yeem ua kom muaj kev vibrations ntawm 3-5 ×, uas ua rau ua rau lub cev tsis muaj zog, damper phaj tawg, thiab cov iav tsheb ciav hlau rattle. Cummins QSK Flange Coupling Kit hais txog qhov no los ntawm kev muab ib qhopre-calculated elastomeric keebnrog tswj durometer thiab aself-centering spline hubuas ua kom cov concentricity nyob rau hauv 0.05 hli, zoo tuning lub driveline dynamic teb rau QSK qhov tshwj xeeb firing xaj thiab torque ripple profile.

QSK 78	78 L	2,000-3,500 hli	Ultra-class tsheb thauj khoom, offshore

Cov khoom siv suav nrogflywheel-sab thiab tsav-sab flange adapters, sib xws nrog SAE 1, 2, thiab 3 qhov ntau thiab tsawg, thiab suav nrog cov khoom siv tsav tsheb (generators: Stamford, Leroy-Somer; gearboxes: ZF, Twin Disc; twj: Sulzer, Weir).

1. Pre-compressed Elastomer nrog Resonant zaus Tuning

Cov khoom siv roj hmab yog lub Hoobkas-compressed rau ib qho tshwj xeeb preload, hloov nws lub ntuj zaus los dagnruab nrablub cav qhov tseem ceeb ntawm kev sib haum xeeb kev txiav txim thiab cov cuab yeej tsav tsheb qhov tseem ceeb ceev ceev. Qhov no "detuning" lub tswv yim tiv thaiv resonance sib tshooj - thawj qhov ua rau damper phaj bolt shearing. Txhua pob khoom yog muab nrog adaim ntawv teb zausqhia txog qhov ntsuas ntuj zaus ntawm kev sib txuas sib txuas, txheeb xyuas los ntawm kev ntsuas cuam tshuam-rauj, muab cov neeg teeb tsa cov ntaub ntawv ntseeg siab.

2. Spline Hub nrog Anti-Fretting Txheej

Internal spline yog coated nrog amolybdenum-disulfide-raws li qhuav zaj duab xis(thickness 12-15 μm) uas txo cov coefficient ntawm kev sib txhuam thiab txo qis fretting hnav nyob rau hauv micro-oscillations. Qhov no yog qhov tseem ceeb tshwj xeeb rau QSK daim ntawv thov uas muaj kev hloov pauv hloov pauv siab, qhov uas hnav spline tuaj yeem ua rau coupling wobble thiab ntxov ntxov bearing tsis ua hauj lwm hauv lub tshuab tsav. Cov txheej yog kuaj rau 10⁶ cycles ntawm 80% ntawm cov ntsuas torque yam tsis muaj kev ntsuas ntsuas.

3. Centering Cone thiab Pilot Nplhaib – Tshem tawm kev ua haujlwm tsis zoo

Cov khoom siv suav nrog amachined pilot nplhaibuas ib ntus nruab nrab ntawm kev sib txuas thaum lub sijhawm teeb tsa. Thaum cov bolts raug torqued, lub nplhaib tsav tsheb raug tshem tawm thiab khaws cia rau yav tom ntej. Qhov no yooj yim ntxiv tshem tawm qhov xav tau ntawm dial gauges thiab multi-point radial checks - ib qho chaw ntawm kev sib dhos yuam kev - thiab xyuas kom meej tias thawj zaug khiav tawm tsis pub dhau 0.05 hli, zoo hauv qab QSK chaw tsim tshuaj paus 0.15 hli txwv.

Hauv kev tshawb fawb ntawm 22 kev teeb tsa (QSK19 txog QSK60) thoob plaws kev siv mining thiab marine:

Bolt tuav: Tsis muaj qhov tshwm sim ntawm kev xoob tom qab thawj 1,000-teev rov ntsuas lub zog (piv rau 18% xav tau rov ua dua nrog cov txuas txuas txuas ntxiv).

Damper lub neej: Lub cav lub hauv ntej damper hloov ncua ncua ncua sij hawm los ntawm qhov nruab nrab ntawm 1,500 teev, ntaus nqi los txo cov kev vibration.

Kev kho tsis raug: Couplings ntsia siv lub nplhaib tsav tau pom qhov nruab nrab qhov kawg ntawm qhov kawg ntawm 0.03 hli, vs . 0.12 hli nrog cov qauv "xav".

Ib tus neeg ua haujlwm sab nrauv tau tshaj tawm tias tom qab hloov mus rau qhov sib txuas no, qhov ntsuas kub ntawm lub iav tsav tau poob los ntawm 6 degree, qhia tias txo qis sab-loading los ntawm kev txhim kho kev sib raug zoo.

Q1: Qhov kev sib txuas no puas tuaj yeem siv nrog SAE 2 vaj tsev yog tias lub cav muaj SAE 1 flywheel vaj tse?
Lub coupling nws tus kheej yog qhov zoo ib yam rau ob lub tsev - qhov sib txawv yog nyob rau hauv lub tswb vaj tsev adapter, uas yog muab cais. Cov khoom siv suav nrog lub nplhaib spacer teeb uas hloov qhov sib txuas rau SAE 1, 2, lossis 3 qhov tob hauv vaj tse. Xaiv qhov tseeb spacer raws li koj lub tsev loj (luam tawm ntawm lub tsev nyob).

Q2: Yuav tsum hloov lub elastomer ntau npaum li cas?
The elastomer has a design life of 15,000 operating hours, but we recommend an inspection (visual + hardness check) at every major overhaul. Signs of aging: surface cracks deeper than 2 mm, hardening (shore >75), los yog cov cim ntawm roj hmab- sib cais rau hlau. Phau ntawv muaj xws li cov txheej txheem kuaj hardness nrog ib tug muab durometer.

Q3: Yuav ua li cas yog tias cov khoom siv tsav lub flange bolt qauv tsis phim lub coupling's?
Cov khoom siv los nrog cov txheej txheem ntawm ob-tus qauv drilling - qhov sib txuas flange muaj ob qho tib si 8-qhov thiab 10-qhov qauv, thiab 12-qhov qauv rau cov qauv loj. Rau cov qauv uas tsis yog tus qauv, peb muab kev cai-drilled flanges (4-lub lim tiam ua ntej). Muab cov khoom siv PCD thiab lub qhov taub qhov taub thaum xaj.

Q4: Kuv puas tuaj yeem rov siv cov bolts txuas?
Tsis yog - bolts yog hom torque-rau-yield; lawv ncab thaum zawm. Reusing lawv txaus ntshai txo preload thiab nws thiaj li loosening. Txhua cov khoom siv suav nrog tag nrho cov txheej txheem tshiab muaj zog bolts (qib 12.9) nrog micro-encapsulated xov locking compound siv. Txiav txim hloov bolts cais yog tias koj xav tau dismantle.

Q5: Dab tsi yog qhov nruab nrab tsav lub nplhaib ua los ntawm, thiab nws puas tuaj yeem siv dua?
Nws yog machined los ntawm cov cuab yeej hardened steel (58 HRC) thiab tuaj yeem rov qab siv tau tas li yog tias nws tseem tsis muaj burrs lossis deformation. Khaws rau hauv lub hnab ntim khoom hauv lub hnab ntim khoom; Yog hais tias nws puas lawm (piv txwv li, poob), hloov nws - lub nplhaib tsav tsheb puas yuav qhia qhov misalignment heev nws txhais tau tias tiv thaiv.

Q6: Puas yog lub coupling yuav tsum muaj lubrication thaum sib dhos?
Lub spline hub muaj lub Hoobkas-tsim zaj duab xis qhuav txheej - tsis txhob ntxiv roj lossis roj, vim nws tuaj yeem nyiam cov khib nyiab thiab ua rau spline hnav. Lub flange bolts yuav tsum tau ntsia kom qhuav (tsis muaj roj ntawm cov xov) kom ua tiav qhov tseeb torque. Qhov tsuas yog lubrication point yog qhov nruab nrab ntawm lub nplhaib tsav - lub teeb smear ntawm anti-seize ntawm lub nplhaib sab nrauv ua rau kev tshem tawm yooj yim dua.

 

Txhawm rau ua kom koj qhov kev yuav khoom tau yooj yim thiab yooj yim, peb muab ntau yam kev xaiv them nyiaj ruaj ntseg:

Peb nyob ntawm no los ua kom koj cov txheej txheem xaj kev txhawj xeeb-dawb - xaiv txoj kev them nyiaj uas ua haujlwm zoo tshaj rau koj!
