10. Izinto ekufuneka ziqwalaselwe xa kufakwa kunye nokugcinwa

10.1 Iiparameter zoFakelo

Indibano ye-SSY004621574 sprocket yenzelwe ukutshintshwa ngokuthe ngqo koomatshini kunye nenxalenye yokuqala. Ukufakelwa kwi-SY1250H kufuna:

• Ukucoca iindawo zokufakelwa zokugqibela ukuze kususwe inkunkuma, izinto ezindala zokutywina, kunye nokugqwala
• Ukuqinisekisa ukuba i-spline okanye i-keyway ayinamonakalo okanye ukuguguleka okugqithisileyo okuya kuthintela ukudluliselwa kwe-torque ngokufanelekileyo
• Ukufaka i-sprocket kwi-final drive output shaft ngamandla afanelekileyo okuhlala
• Ukujika iibholithi zokugcina izinto ngokweemfuno zomenzi (ngesiqhelo zikwi-450–500 N·m, i-torque eyomileyo, efana neemfuno ezifanayo ze-torque enzima ye-excavator bolt)
• Ukusebenzisa i-torque kwipateni yeenkwenkwezi kwiindawo ezininzi zokudlula ukuqinisekisa ukusasazwa komthwalo okufanayo

I-torque efanelekileyo yokufakela ibalulekile; i-under-torquing ingavumela intshukumo ye-axial eyonakalisa i-spline interface, ngelixa i-over-torquing ingaphazamisa i-mounting flange okanye ii-stretch bolts zibe yi-plastic deformation range apho zilahlekelwa khona ngumthamo womthwalo we-clamp.

10.2 Izalathisi zokubeka esweni imeko kunye nokutshintshwa kwayo

Abasebenzi bokulungisa iinqanawa kufuneka bahlole ii-sprockets rhoqo (ngesiqhelo rhoqo emva kweeyure ezingama-500-1,000 zokusebenza kwezicelo zemigodi). Iimpawu eziphambili ezifuna ukutshintshwa kwee-sprocket ziquka:

• Ubunzulu bamazinyo buncitshiswe ngaphezu kwe-15–20% ngokweemfuno zalo zokuqala. Amazinyo agugileyo adala ukungcangcazela okugqithisileyo kwaye akhawulezise ukuguguleka kwezihlangu.
• “Iphiko likaShark” okanye iiprofayili zamazinyo aqhotyoshelweyo—iipateni ezibukhali, ezingalinganiyo zokuguguleka ezibonisa ukuguguleka kwetyathanga elingalinganiyo–ukuguguleka kwe-sprocket.
• Ukuqhekeka okubonakalayo kwiingcambu zeengcambu zamazinyo, ingakumbi xa ujongwa ngamasuntswana anomtsalane okanye ujongwa ngokusondeleyo.
• Ukonakala kwe-spline okanye i-keyway kubonakala ngokudlala ngokujikeleza phakathi kwe-sprocket kunye ne-final drive shaft.
• Ukugqwala okanye umonakalo ochaphazela ukuqina kwamazinyo.

Ngokohlalutyo lokusilela kweshishini, ukusilela kwenkqubo yetshasi kubangela ngaphezulu kwe-35% yokusilela kwe-excavator iyonke, kwaye i-80% yezi ntsilelo zibangelwa kukusilela ukubona ukuguguleka kwecandelo ngexesha. Ngoko ke ukuhlolwa rhoqo kwe-sprocket akunyanzelekanga—sisicwangciso esonga iindleko sokuthintela umonakalo oza emva komsinga.

10.3 Ukuhlolwa Kwangaphambi Kokufakelwa

Xa kufakwa i-sprocket entsha, i-track chain nayo kufuneka ihlolwe ukuba ayigugi. Ukusetyenziswa kwe-sprocket entsha ene-track chain egugileyo—okanye ngokuchaseneyo—kukhawulezisa ukugugiswa kuzo zombini izinto ngenxa yokungafani kwe-geometry yokubandakanya. Eyona nto ibalulekileyo kukutshintsha zonke izinto ngexesha elinye ebezisebenza kunye kwisixhobo esithile soomatshini abanzima. Ukusebenzisa i-chain entsha ene-sprocket egugileyo—okanye ngokuchaseneyo—yindlela emfutshane yokusilela ngokukhawuleza.

10.4 Izikhokelo Zokugcina Nokuphatha

Xa zigcinwa ngaphambi kokufakwa, ii-sprockets mazigcinwe kwindawo eyomileyo, kungcono zigqunywe ngepakethe engangeni mphunga ukuze kuthintelwe ukugqwala kwiindawo ezifakwe ngomatshini. Ii-sprockets mazigcinwe zithe tyaba kwi-pallet okanye kwishelufu; ukubeka ii-sprockets phezulu kwenye nenye kunokonakalisa iiprofayili zamazinyo.

Ukuwa okanye ukubetha ii-sprockets kunokubangela ukuqhekeka okufihlakeleyo okusenokungabonakali emehlweni kodwa okuya kusasazeka phantsi komthwalo. Ukuphathwa kufuneka kwenziwe ngokuphakamisa indibano kusetyenziswa izixhobo zokuphakamisa ezifanelekileyo, kungekhona ngokuqengqeleka okanye ngokuwa. I-phosphate coating esetyenziswa kwii-sprockets ze-CQC TRACK inika ukumelana okuhle nokugqwala ngexesha lokugcina, kodwa ukugcinwa ixesha elide kwiindawo ezinomswakama ophezulu kufuneka kuthintelwe okanye kongezwe ngepakethe eyongezelelweyo ye-vapor corrosion inhibitor (VCI) yokugcina impahla ixesha elide.
