Menene aikin bushewar bazara?

Spring bushewawani abu ne mai haɗaka wanda ya haɗu da ayyuka na abubuwa na roba da bushings a cikin tsarin inji. Ana amfani da shi ko'ina a cikin al'amuran kamar su sha girgiza, buffering, matsayi da rage gogayya. Ana iya taƙaita ainihin ayyukanta kamar haka:

1. Shock sha da tasiri buffering
Bushings na bazara suna ɗaukar girgiza injina da ƙarfin tasiri nan take ta hanyar kayan roba (kamarroba, polyurethane ko karfe spring Tsarin). Misali, a cikin tsarin dakatarwar mota, ana shigar da bushings na bazara tsakanin hannun kulawa da firam, wanda zai iya rage girgizar da ake watsawa ga jiki yadda yakamata ta hanyar kututturen hanya da kuma inganta kwanciyar hankali. Halayen nakasar sa na roba na iya jujjuya firgita mai ƙarfi zuwa ɓarkewar makamashin zafi da rage haɗarin haɓakar tsarin.

2. Rage gogayya da lalacewa
A matsayin matsakaicin mu'amala don sassa masu motsi, bushings na bazara suna rage juzu'i ta hanyar keɓe lamba kai tsaye tsakanin ƙarfe. Misali, tukin motabushewayana amfani da Layer mai mai na ciki ko kayan shafa mai kai (kamar PTFE) don rage juriya na juyawa, yayin da yake kare mujallu daga lalacewa da kuma tsawaita rayuwar sashin. A cikin hanyoyin daidaitawa, elasticity ɗin sa kuma na iya rama ɓarnawar axial da kuma guje wa lalacewa mara kyau da rashin daidaituwa ya haifar.

3. Taimako da matsayi
Bushings na bazara suna ba da tallafi mai sassauƙa don sassa masu motsi kuma suna da ayyukan sakawa. A cikin haɗin gwiwar mutum-mutumi na masana'antu, za su iya jure nauyin radial kuma suna ba da damar ɓata ƙananan kusurwa, tabbatar da sassauƙan motsi na hannun mutum-mutumi yayin da suke kiyaye kwanciyar hankali. Bugu da ƙari, ƙirar riga-kafi na iya daidaita tazara tsakanin abubuwan haɗin gwiwa don hana hayaniya ko asarar daidaitattun lalacewa ta hanyar sassautawa.

4. Kula da surutu
Babban abubuwan damping na kayan roba na iya hana yaduwar amo. Alal misali, amfani dabushing robaA cikin tushe na kayan aikin gida injiniyoyi na iya rage hayaniya aiki da 10-15 decibels. A cikin akwatunan gear, bushings na bazara kuma na iya toshe hanyar watsa sautin tsari da haɓaka aikin NVH (amo, rawar jiki da tsauri).

5. Tsawaita rayuwar kayan aiki
Ta hanyar m sha girgiza, rage amo da gogayya rage, spring bushings muhimmanci rage inji gajiya lalacewa. Kididdiga ta nuna cewa a cikin injiniyoyin injiniya, ingantattun bushings na iya haɓaka rayuwar mahimman abubuwan da aka gyara da fiye da 30%. Yanayin gazawarsa galibi tsufa na abu ne maimakon karaya kwatsam, wanda ya dace don kiyaye tsinkaya.

Zabin kayan abu da ƙira
- Roba bushing: low cost, mai kyau damping yi, amma matalauta high zafin jiki juriya (yawanci <100 ℃).
- Polyurethane bushing: juriya mai ƙarfi mai ƙarfi, dacewa da yanayin yanayin nauyi, amma mai sauƙin fashe a ƙananan zafin jiki.
- Metal spring bushing: high zafin jiki juriya, tsawon rai, mafi yawa amfani a cikin matsananci yanayi kamar aerospace, amma bukatar wani lubrication tsarin.

Aikace-aikace na yau da kullun
- Filin Mota: dakatarwar injin, sandar haɗi mai dakatarwa.
- Kayan aiki na masana'antu: tallafin bututun bututun famfo, buffer injin kayan aikin stamping.
- Madaidaicin kayan aiki: keɓancewar dandamali na gani na girgizar ƙasa, saka kayan aikin semiconductor.

Bushings na bazara suna samun daidaito tsakanin tsayayyen tallafi da daidaitawa mai sassauƙa ta hanyar haɗin injiniyoyi na roba da kimiyyar kayan aiki. Tsarinsa yana buƙatar cikakken la'akari da nau'in kaya (tsaye/tsayi), kewayon mita da abubuwan muhalli. Halin da ake ciki na gaba zai haɓaka zuwa kayan fasaha (kamar magnetorheological elastomers) da daidaitawa don dacewa da ƙarin buƙatun injiniya masu rikitarwa.
