• Ukuvuza kweoyile kwiindawo zokutywina ezidadayo, okubonakaliswa bubumanzi, ukuqokelelwa kwamafutha, okanye iipateni zokutshiza ioyile kwisakhelo somzila.
• Ukujikeleza okubanjwe. Irola engajiki ngokukhululekileyo xa umzila uphakanyisiwe emhlabeni—okanye ekhupha iingxolo zokusila ngexesha lokujikeleza—ikhe yaphulukana neebheringi.

9.3 Iiparameter zoFakelo

Indibano ye-800305455 yenzelwe ukutshintshwa ngokuthe ngqo koomatshini kunye nenxalenye yokuqala. Ukufakelwa kwi-XE370CA kufuna:

• Ukucoca iindawo zokufaka isakhelo sendlela ukuze kususwe inkunkuma kunye nezinto ezindala zokutywina
• Ukuqinisekisa ukuba iibhore zokulungelelanisa i-shaft azinamonakalo okanye ukuguquka
• Ukufaka ii-retaining pins kunye neenkcukacha ze-torque ezibhalwe kwincwadi yenkonzo yomatshini we-XCMG

Ukufakwa kwe-torque efanelekileyo kubalulekile; ukutsalwa kwe-torque engaphelelanga kunokuvumela intshukumo ye-axial ethintela unxibelelwano lwe-seal, ngelixa ukutsalwa kwe-torque engaphezulu kunokuphazamisa i-flange yokufaka okanye konakalise isiphelo se-shaft.

9.4 Izikhokelo Zokugcina Nokuphatha

Xa zigcinwa ngaphambi kokufakwa, iirola ezisezantsi mazigcinwe kwindawo eyomileyo, kungcono zigqunywe ngepakethe engangeni mphunga ukuthintela ukugqwala kwiindawo ezifakwe ngomatshini. Irola mayigcinwe kwindawo ethe tyaba kwindawo ethe tyaba; ukugcina irola esiphelweni sayo kungonakalisa ubuso besitywino okanye kutshintshe isigqubuthelo sokugqibela.

Ukuqengqeleka okanye ukuwisa iindibano kuyingozi ekonakalisa i-flange geometry okanye ubuso be-seal—ukuphathwa kufuneka kwenziwe ngokuphakamisa indibano, kungekhona ukuyiqengqeleka. Kwindawo yokugcina ixesha elide edlula iinyanga ezintandathu, i-roller kufuneka ijikeleziswe rhoqo (rhoqo emva kweentsuku ezingama-30-60) ukuze isasaze i-lubricant kwiindawo zokubeka kunye nokuthintela ukugqwala kwe-galvanic kwindawo ethile okunokwenzeka xa umthwalo opheleleyo we-bushing uhlala ungashukumi kwindawo enye ye-shaft.
