Haɗuwar bearings masu zamiya

Bearings na zamiya wani nau'in bearing ne mai siffa ta gogayya. Ana siffanta su da santsi, aminci, ƙarancin hayaniya, da kuma ikon jure wa kaya masu nauyi da manyan kaya masu tasiri. Dangane da siffofi daban-daban na tsarin, ana iya rarraba su zuwa nau'in haɗin kai, nau'in raba, da nau'in toshe, da sauransu.

1. Haɗa bearings masu zamiya

Bearings masu haɗaka, waɗanda aka fi sani da bushings, sune mafi sauƙin nau'in bearings masu zamiya. Ana haɗa su galibi ta hanyar dannawa da kuma haƙa su. A wasu lokuta na musamman, ana amfani da hanyar hawa zafi. Yawancin bushings an yi su ne da tagulla ko ƙarfe.
    
A lokacin haɗa su, ya kamata a yi taka-tsantsan. Ana iya haɗa su ta hanyar buga su da guduma ta katako ko guduma da bulo na katako. Idan juriyar da ta dace ta yi yawa, ya kamata a danna su da matsi. Ko an buga shi ko an danna shi, dole ne a hana karkatar da shi. Bayan haɗawa, ramin mai da ramin mai ya kamata su kasance a wurin da ake buƙata.
    
Ga bearings masu nakasa bayan an haɗa su, ya kamata a yanke ramukan ciki. Ga ƙananan, ana iya amfani da reamers don yankewa; ga manyan, ya kamata a yi amfani da scrapers. A lokaci guda, a kula da sarrafa wurin da ya dace tare da shaft a cikin kewayon haƙuri.
    
Domin hana hannun shaft ɗin juyawa yayin aiki, ana sanya fil ko sukurori masu haɗaka a saman da ke tsakanin hannun shaft ɗin da kuma wurin da aka haɗa. Saboda bambancin taurin jikin akwatin da kayan shaft ɗin shaft, lokacin haƙa, yana da sauƙi ga ɓangaren haƙa ya jingina zuwa ga ɓangaren kayan mai laushi. Maganganun sune:
* Da farko, yi amfani da samfurin naushi don huda ramin a gefen kayan mai tauri kafin haƙa ramin
* Na biyu, yi amfani da ɗan gajeren injin haƙa rami don ƙara tauri na injin haƙa rami yayin haƙa ramin.

2. Haɗa bearings masu rabuwa

Bearings masu raba, waɗanda aka fi sani da bearings masu raba, suna da tsari mai sauƙi kuma suna da sauƙin daidaitawa da wargazawa. Ana saka harsashi biyu masu ɗaukar nauyi a kan harsashin bearings, kuma ana amfani da gasket a haɗin don daidaita gibin da ya dace.

*A. Haɗa daji mai ɗauke da kaya da kuma Gidaje Masu Haɗawa
Dole ne hulɗar da ke tsakanin harsashin bearing na sama da na ƙasa da ramin ciki na bearing ɗin ya kasance mai kyau. Idan bai cika sharuɗɗan ba, yi amfani da ramin ciki na bearing ɗin harsashin bearing mai kauri a matsayin ma'auni don goge bayan bearing ɗin. A lokaci guda, matakai biyu a ƙarshen bearing ɗin ya kamata su kasance kusa da ƙarshen bearing ɗin biyu. Ga harsashin bearing masu sirara, kawai sai a yi tsakiyar bearing ɗin ya fi na bearing ɗin kusan 0.1mm girma, kuma babu buƙatar goge shi.
    
*B. Bukatun matsayi
Ana sanya bishiyar ɗaukar bearing a cikin gidan ɗaukar bearing kuma ba a yarda ta sami wani motsi ko dai a radial ko a axial. Yawanci, ana tsayar da shi kuma a sanya shi a matakala a ƙarshen daji ko ta hanyar sanya fil.
    
*C. Goge harsashin bearing
Ga harsashin bearings da aka raba, galibi ana amfani da wuraren niƙa shaft ɗin da suka dace. Yawanci, ana goge harsashin bearings da farko, sannan a goge harsashin bearings na sama. Don inganta inganci, ba a buƙatar shigar da harsashin bearings da murfin lokacin goge harsashin bearings. Lokacin da wurin hulɗa na ƙananan bearings ya cika buƙatun, ana matse harsashin bearings na sama da murfin sama sosai. A lokacin goge harsashin bearings na sama, ana ƙara gyara wurin hulɗa na ƙananan bearings. Lokacin gogewa, ana iya daidaita matse shaft ɗin ta hanyar canza kauri na gasket yayin da adadin lokutan gogewa ke ƙaruwa. Lokacin da Murfin hali an matse shi, sandar za ta iya juyawa cikin 'yanci ba tare da wata hanya ta fili ba, kuma wuraren hulɗa sun cika buƙatun, an kammala goge shi.
    
*D. Auna izinin ɗaukar kaya
Ana iya daidaita girman wurin da aka yi amfani da shi ta hanyar gasket ɗin da ke tsakiyar jirgin ko kuma ta hanyar goge daji kai tsaye. Yawanci ana auna wurin da aka yi amfani da shi ta hanyar matse gubar:
1. Ɗauki sassa da dama na wayar gubar da diamita ya fi girma fiye da izinin ɗaukar kaya
2. Sanya su a kan littafin rubutu da kuma saman rabuwar tsakiya
3. A matse goro don a matse saman tsakiyar rabuwar sosai
4. Buɗe goro ɗin sannan a cire murfin da ke ɗauke da shi
5. A hankali cire wayar gubar da aka yi wa launni
6. Yi amfani da ma'aunin micrometer don auna kauri na kowane sashe
        
Dangane da matsakaicin kauri na wayar gubar, ana iya sanin izinin ɗaukar bear. Ya kamata izinin ɗaukar bear ya zama 1.5-2.5 (mm) na diamita na shaft. Idan diamita ya fi girma, ya kamata a ɗauki ƙaramin ƙimar izinin ɗaukar bear. Idan diamita na shaft ya kasance 60mm, izinin ɗaukar bear ya kamata ya kasance tsakanin 0.09 da 0.15mm.

Haɗuwa da bearings masu birgima

Bearings masu birgima suna da fa'idodin ƙarancin gogayya, ƙaramin girman axial, sauƙin maye gurbinsu da sauƙin gyarawa.

Bukatun fasaha don haɗawa:

* Ya kamata a sanya fuskokin ƙarshen bearings masu birgima waɗanda aka yiwa alama da lambobi a cikin alkiblar da ake iya gani don sauƙaƙe tabbatarwa yayin maye gurbin.
* Radius na baka a matakin littafin ko ramin ginin ya kamata ya zama ƙarami fiye da wanda yake daidai da matsayin da ke kan bearing.
* Bayan an haɗa bearing ɗin a kan sandar da kuma a cikin ramin gidan, bai kamata a sami karkacewa ba.
* Daga cikin bearings guda biyu a kan axis ɗaya, dole ne mutum ya sa shaft ɗin ya motsa lokacin da shaft ɗin ya faɗaɗa ta hanyar zafi.
* Lokacin haɗa bearings masu birgima, yana da mahimmanci a hana datti shiga bearings ɗin sosai.
* Bayan haɗawa, bearings ya kamata su yi aiki da sassauƙa, su haifar da ƙarancin amo, kuma zafin aiki gabaɗaya bai kamata ya wuce 65℃ ba.
