Ukuthwala Ukungaphumeleli koKukhathala: Indlela yokuQhutywa koQhagamshelwano oluQhelekileyo olukhokelela kwiiNgxaki kunye nokuSpalling

Ukungaphumeleli kokudinwa kuhlala kungunobangela ophambili womonakalo wokuzala kwangaphambi kwexesha, onoxanduva lokungaphumeleli okungaphezulu kwe-60% kwizicelo zamashishini. Iibheringi zezinto eziqengqelekayo-ezibandakanya umsesane wangaphakathi, umsesane wangaphandle, izinto eziqengqelekayo (iibhola okanye iirola), kunye ne-cage-isebenza phantsi kokulayisha i-cyclic, kunye nezinto ezijikelezayo ngokuqhubekayo zihambisa amandla phakathi kwamakhonkco.

Ngenxa yendawo encinci yoqhagamshelwano phakathi kwezinto eziqengqelekayo kunye ne-raceways, isiphumoUxinzelelo loqhagamshelwano lweHertzianiphezulu kakhulu, ngakumbi phantsi kweemeko zesantya esiphezulu okanye zomthwalo onzima. Le meko igxininisekile yoxinzelelo ikhokelelaukudinwa uxinzelelo, ebonakala njengokugqobhoza komphezulu, iintanda, kwaye ekugqibeleni ukuqhekeka.

Yintoni Ukudinwa Ngoxinzelelo?

Ukudinwa koxinzelelo kubhekisa kwiumonakalo wesakhiwo wendawookubangelwa kukulayisha ngokuphindaphindiweyo umjikelo ngaphantsi kwamandla okugqibela ezinto eziphathekayo. Ngelixa ubuninzi beukuzalaIhlala ine-elastically deformed, ii-microscopic zones zifumana i-plastic deformation ekuhambeni kwexesha, ekugqibeleni iqalisa ukusilela. Inkqubo ikholisa ukuvela ngokwamanqanaba amathathu aqhubekayo:

1. Ukuqaliswa kweMicrocrack

• Yenzeka kumanqanaba angaphantsi komhlaba (0.1–0.3 mm ngaphantsi kwendawo yomdyarho).

• Ibangelwa kukugxininiswa koxinzelelo lwe-cyclic kwi-microstructural imfections.

2. Ukusasazwa kweeNgqondo

• Iintanda zikhula ngokuthe ngcembe kwiindlela zoxinzelelo olukhulu lokucheba.

• Ukuphenjelelwa ziziphene zezinto kunye nemijikelo yokulayisha yokusebenza.

3. Ukuqhekeka kokugqibela

• Umonakalo womphezulu ubonakala njengei-spalling or ukugqobhoza.

• Nje ukuba iintanda zifikelele kubungakanani obubalulekileyo, izinto ziyaphuma kumphezulu.

Iingqwalaselo zokudinwa kwiZithuthi zoMbane oMbi

In iimoto ezinkulu zempahla (LGVs)kwayeizithuthi zempahla enzima(HGVs)-ingakumbi izinto ezahlukeneyo zombane-ukumelana nokudinwa kubaluleke ngakumbi ngenxa yoku:

• Uluhlu olubanzi lwe-RPM: Iinjini zombane zisebenza kuzo zonke iibhendi zesantya esibanzi kuneenjini zokutsha, zinyusa umjikelo wokulayishwa komjikelo.

• Imveliso yeTorque ephezulu: Ukuhanjiswa kwetorque enzima kufuna iibheringi ezinamandla okudinwa okuphuculweyo.

• Impembelelo yobunzima bebhetri: Ubunzima obongezelelweyo beebhetri zokutsalwa ziphakamisa uxinzelelo kumacandelo e-drivetrain, ngakumbiIvili kunye neebheringi zeemoto.

Abaxhasi abaphambili kwiStress Fatigue

√ Ukutshintshana kwemithwalo

Iibheringi kwiinkqubo eziguquguqukayo zihlala zibonakaliswe ngokuhlukaimithwalo ye-radial, axial, kunye nokugoba. Njengoko izinto eziqengqelekayo zijikeleza, uxinzelelo loqhagamshelwano luyatshintsha ngokwebhayisekile, ludala uxinzelelo oluphezulu ngokuhamba kwexesha.

√Iziphene zezinto eziphathekayo

Ukufakwa, i-micro-cracks, kunye ne-voids ngaphakathi kwezinto ezithwalayo zinokusebenza njengeizigxininisi zoxinzelelo, isantya sokuqalisa ukudinwa.

√Ukuthambisa kakubi

Ukuthambisa okungonelanga okanye okuthotyiweyo kuyandaingxabano kunye nobushushu, ukunciphisa amandla okudinwa kunye nokukhawuleza ukunxiba.

√Ufakelo olungafanelekanga

Ukungalungi kakuhle, ukulungelelaniswa okungalunganga, okanye ukuqiniswa ngokugqithiseleyo ngexesha lofakelo kunokuzisa uxinzelelo olungalindelekanga, ukuphazamisa ukusebenza kokuthwala.

Ukuqonda kunye nokunciphisa ukukhathala koxinzelelo kubalulekile ekuqinisekiseni ubomi obude benkonzo kwizicelo ezifunwayo-ingakumbi izithuthi zombane ezinzima. Ngelixa ukuqhubela phambili kwezixhobo kunye netekhnoloji yokulinganisa kuye kwanyusa ukumelana nokudinwa, kufanelekileukukhetha, ukufakwa, kunye nokugcinwazisangundoqo ekusebenzeni kunye nokuthembeka.

Ukusebenzisana kunye abavelisi abanamavainokubonelelaizisombululo ezilungiselelweyokwisicelo sakho esithile. Ukuba iprojekthi yakho ifuna ukusebenza okuphezulu, ukumelana nokudinwaiibheringi, iqela lethu lilapha ukuncedainkxaso yobugcisa kunye neengcebiso zemveliso.
