Raws li cov tub ntxhais tsav tsheb rau siab - nrawm, siab - qhov tseeb looms, qhov tseeb ntawm txhua qhov txuas hauv Niupai Electromechanical cam shedding ntaus ntawv ncaj qha cuam tshuam rau kev du thiab kev ntseeg siab ntawm tag nrho cov kab ke. Thaum lub sij hawm sib dhos los yog kev saib xyuas, yog tias cov fasteners nyob rau hauv lub vaj tse tsis nruj rau lub torque teev thiab ua raws li cov cim kab, nws yuav ua rau cov saw tsis ua haujlwm, cuam tshuam loj heev rau kev tsim khoom.
Cov txiaj ntsig tshwj xeeb yog tshwm sim hauv ob qho hauv qab no:
1. Kev phom sij ntawm kev nruj tsis txaus (tsis ua raws li cov kab kos)
Yog hais tias cov fasteners tsis nruj rau lub zog torque, piv txwv li, cov kab cim tsis sib haum, cov fasteners yuav loosen me ntsis vim kev co thaum lub sij hawm tas mus li siab - ceev ntawm cov khoom siv. Qhov kev xoob no yuav ncaj qha ua rau kom maj mam nce hauv kev ua haujlwm clearance ntawm cov tub ntxhais kinematic khub ntawm lub cam shedding ntaus ntawv- lub conjugate cam thiab lub rotor. Kev tsis sib haum xeeb ntawm kev sib cais yuav cuam tshuam rau txoj cai lij choj ntawm cov lus tsa suab, ua rau muaj kev cuam tshuam loj heev thaum lub sijhawm hloov pauv, uas tshwm sim raws li kev ua haujlwm tsis ruaj khov, kev co tsis zoo, lossis dhia. Qhov no tsis yog - qhov kev txav tsis tu ncua tsis yog tsuas yog tsim cov kev tsis xws luag tab sis kuj tseem ua rau kev hnav txawv txav ntawm qhov chaw ua haujlwm ntawm lub cam phaj thiab lub cam rotor vim qhov nce siab hauv kev cuam tshuam. Nws tuaj yeem ua rau muaj kev puas tsuaj loj xws li pitting thiab cracking, thaum kawg yuam cov khoom siv downtime thiab ua rau cov nqi tu ntau.
2. Kev phom sij dhau ntawm -Tightening (Tshaj Tawm Txoj Kab Npav)
Hloov pauv, yog tias ib tus ntseeg tias "qhov nruj dua qhov zoo dua" thiab siv lub zog torque tshaj tus nqi teev tseg, ua rau muaj kev nruj dua li cov kab kos, nws tseem yuav ua rau muaj qhov tshwm sim loj. Tshaj- nruj tsim kom muaj lub zog ua ntej tshaj qhov kev xav tau tsim, uas tuaj yeem ua rau cov yas elongation ntawm lub ntsia liaj qhov rooj nws tus kheej lossis stripping ntawm cov xov, ua rau nws lub zog tsis muaj zog. Simultaneously, it may cause localized deformation of precision components such as the tightened housing bearing seats, compromising the original assembly accuracy and concentricity of critical parts such as bearings and camshafts, thereby interfering with the motion transmission chain of the entire camshaft opening device and creating hidden faults in the equipment.
Cov txheej txheem ua haujlwm tseem ceeb
Yog li ntawd, thaum lub sij hawm txij nkawm, cov txheej txheem yuav tsum tau nruj me ntsis raws li nram no: Ua ntej zawm lub leveling kov, xyuas kom meej tias nws yog tag nrho rub upwards kom ntseeg tau tias tag nrho cov mechanism nyob rau hauv qhov tseeb "leveling" lub xeev, thiab ces zawm nws mus rau lub torque teev. Rau tag nrho cov fasteners tseem ceeb nyob rau hauv lub vaj tse, ib tug calibrated torque cuab tam yuav tsum tau siv kom uniformly ceev lawv mus rau lub torque qhov tseem ceeb qhia nyob rau hauv cov kev qhia, kom ntseeg tau tias tag nrho cov cim yog precisely ua raws li. Qhov no yog qhov tseem ceeb los xyuas kom meej lub cam qhib lub cuab yeej tswj kev ua haujlwm zoo nyob rau lub sijhawm ntev, tiv thaiv kev poob qis, thiab yog ib qho tseem ceeb ua haujlwm los xyuas kom meej tias Niu hom electromechanical cov khoom ua tiav lawv cov kev tsim thiab kev ua neej.
Nyob rau hauv luv luv, ob qho tib si tsis txaus thiab nruj heev ntawm fasteners yuav ua rau cov khoom siv lub neej. Tsuas yog los ntawm kev ua raws li cov qauv nruj me ntsis tuaj yeem ua kom ruaj khov thiab ua haujlwm tau zoo ntawm cov cuab yeej.
