Izindaba Zenkampani

Ekukhiqizweni kwezimboni nasekusebenzeni kwemishini, ama-bearings, njengezingxenye eziyinhloko, ahlobene ngqo nokuqina nokuphila kwenkonzo yemishini. Uma ikhwalithi yama-bearings ingafiki ezingeni elijwayelekile, ngeke nje ithinte ukusebenza kwemishini, kodwa futhi ingabangela ukulahlekelwa kwezomnotho njengokumiswa komkhiqizo nokugcinwa kwawo. Ngakho-ke, umuntu anganquma kanjani ikhwalithi ye-bearings? Esihlokweni sanamuhla, ake sibe nengxoxo ehlelekile.

Umgodi we-aluminium alloy oqinile oqoshiwe ulula futhi awugqwali. Insimbi engagqwali yochungechunge lwe-3 inokumelana okungcono kokufuthwa ngosawoti. Ukuqina okuphezulu kochungechunge lwe-4 kufanelekile Ama-Ball BearingsI-carbon fiber ihlangabezana nezidingo ezikhanyayo kakhulu nezinamandla aphezulu. Lesi sihloko sichaza kabanzi ngezici ezinhlanu ezinkulu zezinto zomgodi ukuze sikusize uvumelane kahle nezidingo zakho zephrojekthi.

Uma uqala ukuhlola izimfihlakalo ze- Ukuthwala okuqondiles, ungathola ukuthi abakhiqizi abahlukene banikeza izinketho eziningi zezinto zomgodi. Izinto zokwakha zezinhlobo eziningi zokuthwala zihlanganisa imishayo ye-aluminium alloy eqinile, imishayo yensimbi eqinile, izinto ezahlukene zensimbi engagqwali, kanye ne-carbon fiber, njll. Uma ubhekene nezinketho eziningi kangaka, ungase uzizwe udidekile: Kufanele uqale kanjani ukukhetha lapho uqala iphrojekthi entsha? Ungakhathazeki. Lesi sihloko sizokunikeza ukuhlaziywa okuningiliziwe kwezici zezinto zomgodi ngamunye futhi sikunikeze umhlahlandlela wokukhetha ngendlela emfushane necacile.

Ngesikhathi esifanayo, sizophinde sikhulume ngendlela yokusebenzisa ama-ball bearings kulezi zinto zomshafu ngendlela eguquguqukayo ukuze kuhlangatshezwane nezidingo zakho ezahlukene kuphrojekthi.

Okokuqala, ake sibheke ngokujulile izici eziyingqayizivele zomshafti we-aluminium alloy oqinile (6060-T66).

Ama-ceramic bearings amelana nokugqwala, amelana nokushisa futhi alula, okwenza afaneleke ezindaweni ezibucayi kakhulu. Ama-stainless steel bearings anokumelana okunamandla kanye nezindleko eziphansi, futhi afaneleka ezimweni zokusebenza ezijwayelekile. Khetha ngokusekelwe ezimweni zohlelo lokusebenza ukuze uthuthukise ukusebenza kanye nesikhathi sokuphila kwemishini.

Emishinini yomshini, ukukhethwa kwama-bearings kuthinta ngqo ukusebenza kanye nokuphila kwenkonzo yemishini. Ama-bearings e-ceramic kanye nama-bearings ensimbi engagqwali, njengezinhlobo ezimbili ezivamile, ngalinye linezici ezihlukile. Ukuqonda izinzuzo kanye nokungalungi kwawo kuyasiza ekwenzeni izinqumo ezifanele ezimweni ezahlukene zokusetshenziswa.

Abasebenzisi bahlala bekhononda ngokuphila kwenkonzo yama-bearings, kodwa ama-80% ama-bearings ahluleka ngaphambi kwesikhathi ngenxa yokufakwa okungalungile. Ukufakwa kahle kwama-bearings akugcini nje ngokwandisa impilo yawo yenkonzo futhi kunciphise izindleko, kodwa futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza.

Njengoba kwaziwa kahle, ama-bearings ngokwawo ayizingxenye ezisetshenziselwa ukusekela kanye nezingxenye ezisetshenziselwa ukusekela ukujikeleza kuma-shafts. Ama-bearings angahlukaniswa ngezakhiwo zawo zokungqubuzana zibe ama-sliding bearings nama-rolling bearings. Ngokuya kwesiqondiso somthwalo athwele wona, kukhona ama-radial bearings, ama-thrust bearings, kanye nama-radial thrust bearings, njll.

Ama-bearings yizingxenye ezivame ukusetshenziswa emishinini yemishini. Umsebenzi wawo oyinhloko ukusekela izingxenye ezijikelezayo zemishini, ukunciphisa i-friction coefficient ngesikhathi sokuhamba kwawo, nokuqinisekisa ukunemba kwawo kokujikeleza. Indlela yokunquma ukufakwa okuphambene kwama-bearings ibaluleke kakhulu ekusetshenzisweni nasekugcinweni okufanele kwama-bearings. Okulandelayo kuzonikeza isingeniso esiningiliziwe ezindleleni zokunquma ukufakwa okulungile nokuphambene kwama-bearings.

Ama-roller bearings ayisilinda, njengezingxenye eziyinhloko zezinhlelo zemishini, athembele ekunakekelweni okuhlelekile kwesikhathi sawo sokuphila nokusebenza kwawo. Izinqubo zokulungisa ezilandelayo zenziwa isinyathelo ngesinyathelo ngokusekelwe ezindinganisweni zemboni, ezihlanganisa ukulungiswa kokuhlukaniswa, ukuhlanza nokuhlola, ukufakwa kokuthambisa, kanye nokuqapha okulandelayo ukuqinisekisa ukusebenza okuzinzile kwama-bearings ngaphansi kwezimo zokusebenza ezinzima.

Ezweni lemishini, ama-thrust bearings ayizici ezibalulekile eziqinisekisa ukusebenza okuzinzile futhi akhuthaza intuthuko enembile embonini. Adlulisela amandla e-axial ngokusebenzisa izinto ezigoqayo futhi, ngezakhiwo ezahlukahlukene ezifana namabhola, ama-rollers nama-needle rollers, asetshenziswa ekudlulisweni kwezimoto, ezinhlelweni zokuhambisa umoya zasolwandle kanye nezinjini ze-aero, esekela intuthuko ephumelelayo yezimboni ezahlukahlukene ngokusebenza kwayo okuyingqayizivele.

Umehluko omkhulu phakathi kwama-ball bearings nama-roller bearings ukuma kanye nemodi yokuxhumana yento egingqikayo, okuthinta ngqo ukusebenza kwayo kanye nezimo zokusetshenziswa.

Ngezinye izikhathi sithola impendulo evela kumakhasimende mayelana nendlela ama-bearings okufanele anakekelwe futhi anakekelwe ngayo. Ngakho-ke namuhla ake sixoxe ngokugcinwa nokugcinwa kwama-bearings.

Ama-bearings amamodeli ahlukene asetshenziswa kabanzi emikhakheni eyahlukene yezimboni ngenxa yezimpawu zawo zesakhiwo kanye nokwehluka kokusebenza.
