Uyini umsebenzi we-spring bushing?

Spring bushingkuyingxenye ehlanganisiwe ehlanganisa imisebenzi yezakhi ezinwebekayo kanye nama-bushings ezinhlelweni zemishini. Isetshenziswa kakhulu ezimeni ezinjengokumunca ukushaqeka, ukubhafa, ukubeka indawo kanye nokunciphisa ukungqubuzana. Imisebenzi yayo ewumongo ingafingqwa ngale ndlela elandelayo:

1. Ukumuncwa ukushaqeka kanye nokubhafa komthelela
Izihlahla zasentwasahlobo zimunca ukudlidliza kwemishini kanye namandla okuthonya ngokushesha ngezinto ezinwebekayo (njengeirabha, polyurethane noma metal spring izakhiwo). Isibonelo, ohlelweni lokumiswa kwezimoto, ama-spring bushings afakwa phakathi kwengalo yokulawula kanye nohlaka, okunganciphisa ngempumelelo ukudlidliza okudluliselwa emzimbeni ngamaqhubu omgwaqo futhi kuthuthukise ukunethezeka kokugibela. Izici zayo zokuguga ezinwebekayo zingaguqula ukudlidliza kwe-high-frequency kube ukuchithwa kwamandla okushisa futhi kunciphise ingozi yokuzwakala kwesistimu.

2. Yehlisa ukungqubuzana nokuguga
Njengesixhumi esibonakalayo sezingxenye ezihambayo, ama-spring bushings anciphisa i-coefficient yokungqubuzana ngokuhlukanisa ukuxhumana okuqondile phakathi kwezinsimbi. Isibonelo, i-drive shaftbushingisebenzisa isendlalelo sokuthambisa sangaphakathi noma okokusebenza okuzithambisayo (okufana ne-PTFE) ukuze kuncishiswe ukumelana nokujikeleza, kuyilapho ivikela iphephabhuku ekugugeni nokwelula impilo yengxenye. Ezindleleni eziphindaphindayo, ukunwebeka kwayo kungaphinda kunxephezele ukuchezuka kwe-axial futhi kugweme ukugqokwa okungavamile okubangelwa ukungahambi kahle.

3. Ukusekela nokubeka
Ama-spring bushings ahlinzeka ngokusekela okuguquguqukayo kwezingxenye ezihambayo futhi abe nemisebenzi yokubeka. Emajoyini amarobhothi ezimboni, angakwazi ukumelana nemithwalo yeradial futhi avumele ukuchezuka kwama-engeli amancane, aqinisekise ukunyakaza okuguquguqukayo kwengalo yerobhothi kuyilapho kugcinwa ukuzinza kwesakhiwo. Ngaphezu kwalokho, idizayini yokulayisha kuqala ingalungisa igebe phakathi kwezingxenye ukuvimbela umsindo noma ukulahleka okunembayo okubangelwa ukuxega.

4. Ukulawula umsindo
Izakhiwo zokudambisa eziphezulu zezinto ezinwebekayo zingacindezela ukusakazeka komsindo wokudlidliza. Ngokwesibonelo, ukusetshenziswaizihlahla zenjolobangaphansi kwezinjini zemishini yasendlini inganciphisa umsindo osebenzayo ngama-decibel ayi-10-15. Kuma-gearbox, ama-spring bushings angaphinda avimbe indlela yokudlulisa yomsindo wesakhiwo futhi athuthukise ukusebenza kwe-NVH (umsindo, ukudlidliza kanye nokhahlo).

5. Nweba impilo yemishini
Ngokumunca ngokuphelele ukushaqeka, ukunciphisa umsindo kanye nokunciphisa ukungqubuzana, ama-spring bushings anciphisa kakhulu ukulimala kokukhathala. Izibalo zibonisa ukuthi emishinini yobunjiniyela, ama-bushings athuthukisiwe angakhuphula impilo yezingxenye ezibalulekile ngaphezu kwama-30%. Imodi yokwehluleka kwayo ngokuvamile iwukuguga okubonakalayo kunokuphuka kungazelelwe, okulungele ukulungiswa okubikezelwayo.

Ukukhethwa kwempahla nokuklama
- I-Rubber bushing: izindleko eziphansi, ukusebenza kahle kokumanzisa, kodwa ukumelana nezinga lokushisa eliphansi (imvamisa engu-<100℃).
- I-polyurethane bushing: ukumelana nokugqoka okuqinile, kulungele izimo zomthwalo ophezulu, kodwa kulula ukubola ekushiseni okuphansi.
- I-Metal spring bushing: ukumelana nokushisa okuphezulu, impilo ende, esetshenziswa kakhulu ezindaweni ezibucayi njenge-aerospace, kodwa idinga uhlelo lokuthambisa.

Izinhlelo zokusebenza ezijwayelekile
- Inkambu yezimoto: ukumiswa kwenjini, induku yokuxhuma yokumiswa.
- Imishini yezimboni: ukusekelwa kwepayipi levalvu yephampu, isivimbeli sesikhunta sethuluzi lomshini wokugxiviza.
- Amathuluzi anembile: iplatifomu ye-optical seismic isolation, ukuma kwemishini ye-semiconductor.

Izihlahla zasentwasahlobo zithola ibhalansi phakathi kokusekelwa okuqinile nokulungiswa okuvumelana nezimo ngokuhlanganiswa komshini wokunwebeka nesayensi yezinto ezibonakalayo. Idizayini yayo idinga ukucubungulisisa uhlobo lomthwalo (i-static/dynamic), ibanga lemvamisa kanye nezici zemvelo. Umkhuba wesikhathi esizayo uzothuthukela ekusetshenzisweni kwezinto ezihlakaniphile (njengama-magnetorheological elastomers) kanye ne-modularization ukuze ivumelane nezidingo zobunjiniyela eziyinkimbinkimbi.
