I-bearing bushing, ingxenye ebalulekile yomshini, empeleni iyi-bushing efakwe ku-shaft. Umsebenzi wayo oyinhloko ukusekela i-shaft nokunciphisa kakhulu i-coefficient of friction. Yenziwe kakhulu ngensimbi futhi ingazivumelanisa nezimo eziyinkimbinkimbi njengokushisa okuphezulu, ukucindezela okuphezulu, isivinini esikhulu kanye nokunemba okuphezulu. I-bearing bushing ayinciphisi nje kuphela indawo yokuxhumana phakathi kwe-shaft nensimbi yangaphandle, ngaleyo ndlela inciphise ngempumelelo ukuguguleka kwe-shaft, kodwa futhi yandisa kakhulu impilo yenkonzo ye-shaft. Ngaphezu kwalokho, kunezinhlobo ezahlukene ze-bearing bushing.

I Ukuthwala Okujikayo Indlu yokuhlala uhlobo lwendlu enkulu nenkulu kakhulu yokuthwala enesakhiwo esikhethekile esingamelana nemithwalo ebanzi. Inesakhiwo esincane, ukujikeleza okubucayi, kanye nokufakwa nokugcinwa okulula. Lapho kukhona amabheringi, kumele kube namaphuzu okusekela. Indawo yokusekela yangaphakathi yokuthwala yi-shaft, kanti ukwesekwa kwangaphandle yilokho okwaziwa ngokuthi indlu yokuthwala.

Izinzuzo kanye nokungalungi kwenaliti i-roller amabheringi

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.

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.

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.

I-shaft eqinile ye-aluminium anodized alloy ilula futhi imelana nokugqwala. Insimbi engagqwali yochungechunge lwe-3 inokumelana okungcono kokufuthwa ngosawoti. Ubulukhuni obuphezulu bochungechunge lwe-4 bufanelekela ama-ball bearings. I-carbon fiber ihlangabezana nezidingo ezikhanyayo kakhulu nezinamandla aphezulu. Lesi sihloko sichaza kabanzi ngezici ezinhlanu ezinkulu zezinto ze-shaft ukuze sikusize uvumelane kahle nezidingo zakho zephrojekthi.

Uma uqala ukuhlola izimfihlakalo zama-linear bearings, ungathola ukuthi abakhiqizi abahlukene banikeza izinketho eziningi zezinto zomgodi. Izinto zokwakha zezinhlobo eziningi zomgodi zifaka phakathi imishayo ye-aluminium alloy eqinile, imishayo yensimbi eqinile, izinto 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.
