Sisebenzisa okungenani ama-bearings angu-200 nsuku zonke ekuphileni kwethu. Kuguqule izimpilo zethu. Manje ososayensi nabo banikeza ama-bearings ngobuchopho obuhlakaniphile, ukuze bukwazi ukucabanga nokukhuluma. Ngale ndlela, kuma-bearings anemba kusitimela wesivinini esikhulu, abantu bangakwazi futhi ukuqonda sonke isimo sama-bearings ngaphandle kokunakekelwa. Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ingcindezi kuma-bearings iye yaba namandla futhi iphakeme, futhi nezidingo zekhwalithi zizoba phezulu.

Umqondo nokuhlukaniswa kwama-bearings aginqikayo

Ama-bearings avamile ngokuvamile akhiwa izinto eziyisisekelo ezifana namasongo amabili (okungukuthi iringi yangaphakathi, iringi yangaphandle), izakhi eziginqikayo namakheji.

Imisebenzi Emine ye-Rolling Bearings

Indandatho yangaphakathi ngokuvamile ilingana kahle ne-shaft futhi izungeza ne-shaft.

Iringi yangaphandle ivamise ukusebenzisana nembobo yesihlalo esithwele noma igobolondo lengxenye ewumshini ukuze idlale indima yokusekela.

Izakhi ezigoqayo zihlelwe ngokulinganayo phakathi kwamasongo angaphakathi nangaphandle ngosizo lwekheji, futhi ukuma komugqa, usayizi kanye nobuningi kunquma ngokuqondile umthamo wokuthwala wokuthwala.

Ikheji ihlukanisa ngokulinganayo izakhi ezigoqayo futhi iqondise izinto ezigoqayo ukuze zihambe kumzila olungile.

"I-Thrust needle roller bearings"

Ama-bearings ahlukanisekayo akhiwa izindandatho zomzila womjaho, amarola enaliti namakheji, futhi angahlanganiswa nezindandatho ezigxiviziwe zomzila womjaho (W) noma izindandatho ezisikiwe eziwugqinsi (WS). Ama-bearings angahlukaniseki ama-bearings ahlanganisiwe akhiwe amasongo omzila womjaho anezigxivizo ezinembayo, amarola enaliti nama-cage assemblies. Lolu hlobo lokuthwala lungamelana nomthwalo we-axial unidirectional. Ithatha indawo encane futhi ihambisana nomklamo ohlangene womshini. Iningi lazo lisebenzisa kuphela i-roller yenaliti kanye nezingxenye zekheji, futhi zisebenzisa indawo ekhuphukayo ye-shaft kanye nezindlu njengendawo yomjaho.

“I-Tapered Roller Bearings“

Lolu hlobo lokuthwala lufakwe ama-roller ama-truncated ancishisiwe, aqondiswa izimbambo ezinkulu zendandatho yangaphakathi. Ekwakhiweni, amathrethi ezindawo eziqondile zendlela yomjaho eyindandatho engaphakathi, indawo yomjaho eyindandatho yangaphandle kanye nendawo eginqikayo iyaphambana endaweni ethile emgqeni ophakathi nendawo. Amabheringi anomugqa owodwa angathwala umthwalo we-radial kanye nomthwalo we-axial wendlela eyodwa, futhi ama-axial-rowu amabili angathwala umthwalo we-radial kanye nomthwalo we-axial wezindlela ezimbili, futhi afanele ukuthwala umthwalo osindayo kanye nomthwalo womthelela.

"Ama-Cylindrical Roller Bearings"

Ama-roller bearings angama-cylindrical angahlukaniswa abe umugqa owodwa, ama-double-row kanye nama-multi-row cylindrical roller bearings ngokuya ngenani lemigqa yezinto ezigoqayo ezisetshenziswa ekuphatheni. Phakathi kwazo, ama-roller ama-cylindrical roller anemigqa eyodwa asetshenziswa kakhulu. Ngaphezu kwalokho, kukhona ama-roller bearings angama-cylindrical anezinye izakhiwo ezifana ne-single-row noma ama-roller aphelele aphelele anemigqa emibili.

Umugqa owodwa oyi-cylindrical roller bearings ihlukaniswe ngohlobo lwe-N, uhlobo lwe-NU, uhlobo lwe-NJ, uhlobo lwe-NF nohlobo lwe-NUP ngokuya ngombambo oluhlukene lweringi. Ama-Cylindrical roller bearings anomthamo omkhulu we-radial load, futhi angathwala nomthwalo we-axial wendlela eyodwa noma ezimbili ngokuya ngesakhiwo sombambo wendandatho. Uhlobo lwe-NN kanye nohlobo lwe-NNU lwamarola angama-double cylindrical roller bearings ahlangene ngesakhiwo, aqinile ngokuqina, amakhulu ekuthwaleni umthamo kanye nokushintshashintsha okuncane ngemva kokulayishwa, futhi asetshenziswa kakhulu ekusekeleni ama-spindle amathuluzi omshini. I-FC, i-FCD, i-FCDP yohlobo lwe-4-row cylindrical roller bearings ingamelana nemithwalo emikhulu yama-radial, futhi isetshenziswa kakhulu emishinini esindayo njengezigayo eziginqikayo.

“I-Spherical roller bear“

Lolu hlobo lokuthwala lufakwe ama-rollers ayindilinga phakathi kweringi yangaphandle yomjaho oyindilinga kanye neringi yangaphakathi yomjaho ophindwe kabili. Ngokusho kwezakhiwo zangaphakathi ezahlukene, ihlukaniswe yaba izinhlobo ezine: R, RH, RHA kanye ne-SR. Njengoba isikhungo se-arc somzila wangaphandle wendandatho sihambisana nesikhungo sokuthwala, sinokusebenza kokuziqondisa, ngakho-ke singakwazi ukulungisa ngokuzenzakalelayo ukungahambi kahle kwe-shaft okubangelwa ukuchezuka noma ukungahambi kahle kwe-shaft noma izindlu. Ingathwala i-radial load kanye ne-bidirectional axial load. Ikakhulukazi, umthamo we-radial load mkhulu, futhi ufanelekile ukuthwala imithwalo esindayo kanye nemithwalo yokushaqeka. I-Metal processing WeChat, okuqukethwe kuhle, kufanelekile ukunakwa. Ama-bore bearings angahlanganiswa futhi ahlakazwe ku-shaft ngokusebenzisa izinsimbi noma imikhono yokuhoxisa. Ama-roller bearings angama-spherical angathwala umthwalo omkhulu we-radial, kodwa futhi angathwala umthwalo othile we-axial. Umzila womjaho wendandatho yangaphandle walolu hlobo lokuthwala uyindilinga, ngakho unokusebenza kokuziqondanisa. Lapho i-shaft igobile noma ihlotshiswe ngaphansi kokuphoqelelwa, ukuze ukuthambekela okuhlobene komugqa ophakathi kwendandatho yangaphakathi kanye nomugqa ophakathi kwendandatho yangaphandle ungadluli ku-1 ° ~ 2.5 °, ukuthwala kusengasebenza. .

“I-Trust Roller Bearing“

Ama-thrust roller bearings ahlanganisa ama-thrust roller bearings, ama-thrust cylindrical roller bearings nama-thrust roller bearings. I-Thrust spherical roller bearings ingathwala kokubili imithwalo ye-axial ne-radial, kodwa umthwalo we-radial akufanele udlule u-55% womthwalo we-axial. Esinye isici esibalulekile salolu hlobo lwe-bearing ukusebenza kwayo kokuziqondanisa, okwenza kungabi nokuzwela ukungahambi kahle nokuphambuka kwe-shaft. Vele ulayishe u-P no-P. Akukho ngaphezu kuka-0.05C, futhi indandatho ye-shaft iyajikeleza, ukuthwala kuvumela uhla oluthile lwe-engeli yokuziqondanisa. Amanani amancane afanele ama-bearings amakhulu, futhi i-engeli yokuqondanisa evumelekile izokwehla njengoba umthwalo ukhula.

"Ama-Spherical Bearings"

Faka ama-spherical bearings asetshenziswa kangcono ezinhlelweni ezidinga okokusebenza okulula kanye nezingxenye, njengemishini yezolimo, izinhlelo zokuhamba noma imishini yokwakha.

“I-Angular Contact Bearing“

Ama-angular ball bearings angathwala umthwalo we-radial kanye nomthwalo we-axial ngesikhathi esifanayo, futhi angathwala umthwalo ohlanzekile we-axial, futhi isivinini somkhawulo siphezulu. Ikhono lalolu hlobo lokuthwala ukuthwala umthwalo we-axial linqunywa i-angle yokuxhumana. Uma i-engeli yokuxhumana inkulu, ikhono eliphezulu lokuthwala umthwalo we-axial.
