10. Izinto Okumelwe Uzicabangele Zokufaka Nokulungisa

10.1 Amapharamitha Okufaka

I-SSY004621574 sprocket assembly yenzelwe ukushintshana okuqondile kwemishini nengxenye yokuqala. Ukufakwa ku-SY1250H kudinga:

• Ukuhlanza izindawo zokugcina zokufaka ukuze kususwe udoti, izinto ezindala zokuvala, kanye nokugqwala
• Ukuqinisekisa ukuthi i-spline noma i-keyway ayinawo umonakalo noma ukuguguleka ngokweqile okungavimbela ukudluliswa kwe-torque efanele
• Ukufaka i-sprocket kushafu yokugcina yokukhipha idrayivu ngamandla afanele okuhlala
• Ukushintsha amabhawodi okugcina ngokwezidingo zomenzi (ngokuvamile aphakathi kuka-450–500 N·m, i-torque eyomile, efana nezidingo ezifanayo ze-torque yebhawodi yokwemba esindayo)
• Ukusebenzisa i-torque kuphethini yenkanyezi phakathi kwamaphasi amaningi ukuqinisekisa ukusatshalaliswa komthwalo okufanayo

I-torque efanele yokufaka ibalulekile; ukugoba okungafanele kungavumela ukunyakaza kwe-axial okulimaza i-interface ye-spline, kuyilapho ukugoba ngokweqile kungaphazamisa i-flange yokufaka noma ama-stretch bolts abe yi-plastic deformation range lapho elahlekelwa khona umthamo womthwalo we-clamp.

10.2 Izinkomba Zokuqapha Isimo Nokufaka Esimweni Esisha

Abasebenzi bokulungisa izimoto kufanele bahlole ama-sprocket ngezikhathi ezithile (ngokuvamile njalo emahoreni okusebenza angu-500-1,000 ezicelo zokumba). Izinkomba ezibalulekile ezidinga ukushintshwa kwama-sprocket zifaka:

• Ukujula kwamazinyo kuncishiswe ngaphezu kuka-15–20% kusukela ekuchazweni kokuqala. Amazinyo agugile adala ukudlidliza okukhulu futhi asheshise ukuguguleka kwezicathulo.
• “Iphiko likaShark” noma amaphrofayili ezinyo eliboshwe—amaphethini okuguguleka abukhali, angalingani abonisa ukuguguleka kweketanga okungafani–ukuguguleka kwe-sprocket.
• Ukuqhekeka okubonakalayo ezicutshini zezimpande zamazinyo, ikakhulukazi uma kuhlolwa izinhlayiya ezisebenzisa ugesi noma kuhlolwa ngokuseduze.
• Ukuguguleka kwe-spline noma i-keyway okubonakaliswa ukudlala ngokujikeleza phakathi kwe-sprocket kanye ne-final drive shaft.
• Ukugqwala noma umonakalo olimaza ubuqotho bamazinyo.

Ngokusho kokuhlaziywa kokuhluleka kwemboni, ukwehluleka kwesistimu ye-chassis kubangela ngaphezu kwama-35% okwehluleka okuphelele kokumba, kanti ama-80% alokhu kwehluleka kubangelwa ukwehluleka ukubona ukuguguleka kwezingxenye ngesikhathi. Ngakho-ke ukuhlolwa okuvamile kwe-sprocket akuyona into ongayikhetha—kuyisu elingabizi kakhulu lokuvimbela umonakalo ongezansi.

10.3 Ukuhlolwa Kwangaphambi Kokufakwa

Uma ufaka i-sprocket entsha, i-track chain kufanele futhi ihlolwe ukuthi iyaguga yini. Ukusetshenziswa kwe-sprocket entsha ene-track chain egugile—noma okuphambene nalokho—kusheshisa ukuguguleka kuzo zombili izingxenye ngenxa yokungafani kwe-geometry yokubandakanya. Isici esibaluleke kakhulu ukufaka zonke izingxenye ngesikhathi esisodwa ebezisebenza ndawonye emshinini othile osindayo. Ukusebenzisa i-chain entsha ene-sprocket egugile—noma okuphambene nalokho—kuyindlela enqamulelayo yokwehluleka okusheshayo.

10.4 Iziqondiso Zokugcina Nokuphatha

Uma igcinwa ngaphambi kokufakwa, ama-sprocket kufanele agcinwe ezindaweni ezomile, kungcono asongwe ngepakethe engangeni umhwamuko ukuze kuvinjelwe ukugqwala ezindaweni ezifakwe umshini. Ama-sprocket kufanele agcinwe ethe tyaba epalethini noma eshalofini; ukubeka ama-sprocket ngqo phezu komunye nomunye kungalimaza amaphrofayili amazinyo.

Ukuwa noma ukushaya ama-sprocket kungabangela ukuqhekeka okufihliwe okungase kungabonakali emehlweni kodwa okuzosakazeka ngaphansi komthwalo. Ukuphathwa kufanele kwenziwe ngokuphakamisa i-assembly kusetshenziswa imishini yokuphakamisa efanele, hhayi ngokugingqa noma ngokuwa. Isembozo se-phosphate esisetshenziswa kuma-sprocket e-CQC TRACK sinikeza ukumelana okuhle kokugqwala ngesikhathi sokugcina, kodwa isitoreji eside ezindaweni ezinomswakama ophezulu kufanele sigwenywe noma sigcwaliswe ngephakheji eyengeziwe ye-vapor corrosion inhibitor (VCI) yokugcina impahla isikhathi eside.
