Iukuzalaukusekelwa kwe-mechanical drive shaft, isiqinisekiso esibalulekile sokusebenza, ukusebenza nokusebenza kahle komshini oyinhloko, futhi kubizwa ngokuthi "inhlanganisela" yemishini nemishini. Iqhaza layo elibalulekile ukudlulisa amandla nokunyakaza nokunciphisa ukulahleka kokungqubuzana.
I-China ingenye yemiphakathi emine yasendulo. Ubuchwepheshe basendulo baseShayina babukhazimula kakhulu, futhi lezi zinto ezine ezisunguliwe zaba nomthelela omkhulu ezizukulwaneni ezizayo. I-China futhi yizwe elaqala ukudala nokusungula ama-bearings. Eminyakeni engaphezu kuka-4,000 edlule, kwavela izimoto eChina futhi zaqala ukufaka ama-sliding bearings. Ngesikhathi seZhou Dynasty, ukusetshenziswa kwamafutha ezilwane ukuthwala ubuchwepheshe bokugcoba kwasungulwa. Phakathi Nenkathi Yamazwe Alwayo, iShayina kancane kancane yaqala ukwenza ama-shaft tile ngensimbi. UGuo Shoujing, usosayensi woBukhosi baseYuan, wayesungule ubuchwepheshe bokusekela okujikelezayo (i-turntable bear). Esikhathini se-Qing Dynasty, ama-cylindrical roller bearings ayenziwa ngendlela yesimanjemanje. Ngesikhathi seRiphabhulikhi yaseChina, i-China kancane kancane yaqala ukukhiqiza ngobuningi nokucutshungulwa kwama-bearings, futhi yakhiqiza i-Wafangdian, i-Shanghai enezisekelo ezimbili zokukhiqiza nokukhiqiza. Ngemuva kokusungulwa kweRiphabhulikhi yaseShayina, imboni yezokukhiqiza yaseChina yathuthuka ngokushesha, futhi ekugcineni yabeka iphethini eliphelele lamanje.ukuthuthukiswa kwemboni ethwalayo. Nakuba i-China isivele yaba yizwe lesithathu ngobukhulu elikhiqizayo nokuthengisa emhlabeni.

Ngokuthuthuka okusheshayo kobuchwepheshe obuphezulu nobusha obufana ne-aerospace, imboni yenuzi, ikhompuyutha ye-electronics, amathuluzi abonakalayo nakagesi, kanye nemishini enembayo, imboni ephethe umhlaba wonke ekhombisa izinga lamanje lesayensi nobuchwepheshe ingene enkathini entsha yokuqanjwa kabusha okuphelele kokukhiqiza. ubuchwepheshe, izinhlobo ezithuthukayo ngokushesha, ziqinisa ngamandla ukusebenza, ukunemba, nokuvuthwa nokuphelela.
Ngokuqhubeka okuqhubekayo komnotho waseShayina kanye nokwenza ngcono okuqhubekayo kokuzenzakalela, izidingo zomsingathi zizoba phezulu kakhulu, bese ukusebenza kanye namazinga obuchwepheshe ethimba eliphethe azokhula ngokuya phezulu, imikhiqizo emisha iyaqhubeka nokuvela, isidingo nakanjani izoba nkulu futhi ibe nkulu.
Umbuso uyaqhubeka nokwandisa imizamo yokonga ugesi kanye nokunciphisa ukungcola kanye nokwakha umphakathi wokonga ugesi ngokuqinisekile uzosheshisa inqubo yokuguqulwa yokonga ugesi kanye nokunciphisa ukusetshenziswa kwezimboni zendabuko. Ngaphezu kwalokho, ukukhuthaza intuthuko esheshayo yemboni yezamandla entsha kuzoletha amathuba amakhulu enqubekelaphambili yeimboni yokuzala. Ngakho-ke, imboni ethwalayo izoqhubeka nokukhula ngokushesha esikhathini esizayo.
