Daga mahangar haɗin kai da ke sama, idan an wargaza igiyar kuma an haɗa ta sau da yawa, za a iya samun tazara tsakanin zobe na ciki da mujallar, dole ne a gyara mujallar kafin a iya amfani da ita.

Lokacin da dacewa da ke tsakanin igiya da igiya ya yi sako-sako, wasu ma'aikatan kulawa suna amfani da ƙwanƙwasa ko buga saman sandar ɗin don kada saman sandar a ƙoƙarin samun madaidaicin wuri mai dacewa. Wannan ba wai kawai ya lalata siffar geometric na saman shaft ba, yana sa mai ɗaukar nauyi ba zai sami matsayi na tsakiya ba a lokacin shigarwa da skews, amma kuma ɓangaren da aka yi da shi zai zama mai laushi kuma ya zama maras kyau. Hanyar kulawa daidai shine a fara niƙa da gyara jarida, sannan a goge ko fesa jaridar.

2. Ana sawa kejin jujjuyawar jujjuyawar, gurɓatacce ko karye

①. Lokacin hada zoben ciki da na waje na mirgina, saboda yawan tsangwama, ƙwallo masu ɗaukar hoto suna makale a cikin zoben wurin zama, kuma ana iya matse cage mai ɗaukar nauyi yayin aiki. Sabili da haka, ya kamata a yi ma'auni yayin taro don tabbatar da tsangwama daidai.

②. Lubrication na crankshaft bearing shine nau'in fantsama. Lokacin da abin hawa ya rasa ko kuma ba shi da mai mai mai, musamman lokacin da nauyin da ke aiki a kan nauyin ya yi girma, zafin jiki yana tashi. Gabaɗaya, zazzabi na zoben ciki na ɗaukar hoto yana da kusan 10 ° C sama da na zoben waje. Domin fadada yanayin zafi na zobe na ciki da na waje ya bambanta, ratar da ke tsakanin ƙwallon da hanyar tsere ta ɓace, kuma kejin yana yiwuwa ya matse lokacin da abin hawa yana gudana. Don haka, a lokacin da ake shigar da ƙugiya, ya kamata a shafa mai mai tsabta mai tsabta a kan titin tsere don hana mai mai daga fantsama da haifar da bushewa.

3. Titin tseren birgima da birgima saman peeling

①. Kwasfa da ke haifar da nauyin tasiri da madaidaicin danniya. Abubuwan da ke jujjuyawa na ɗaukar hoto da hanyoyin tseren zobe na ciki da na waje duk an yi su ne da lodi mai motsi na keke-da-keke, wanda ke haifar da canjin yanayin cyclically. Lokacin da adadin zagayowar damuwa ya kai wani ƙima, ƙarancin gajiya yana faruwa akan saman aiki na abubuwan birgima ko hanyoyin tseren zobe na ciki da na waje. Idan nauyin ɗaukar nauyi ya yi yawa, wannan gajiyar za ta ƙaru. Bugu da ƙari, idan an shigar da igiya ba daidai ba kuma an lanƙwasa igiya, hanyar tseren na iya barewa. Ƙaƙwalwar tashi da injin injin ɗin suna sanye da ma'aunin nauyi, kuma lokacin jujjuyawar inertia da aka samar yana daidaitawa tare da lokacin jujjuyawar inertia wanda ɓangaren jujjuyawar injin ɗin ke samarwa. Idan lokacin da aka samar na inertia bai daidaita ba, injin zai yi rawar jiki sosai bayan gobara, wanda zai kara yawan matsananciyar damuwa da zagayowar damuwa, yana haifar da titin tsere da na'ura mai juyi don barewa da wuri.

Don kauce wa spalling a saman filin tseren da abubuwa masu birgima, ya kamata a kauce wa ƙarin kaya da girgizar da ba ta dace ba yayin amfani da ita, ya kamata a yi amfani da magudanar ruwa da sauri da kyau yayin aiki don hana tarakta daga fashe, kuma ya kamata a kasance da kafaffen kusoshi na jiki. ana duba akai-akai don hana sassautawa.

②. Saboda barbashi masu wuyar waje suna faɗowa akan madaidaicin saman harsashi ko tsakanin madaidaicin saman shaft da zoben, siffar hanyar tseren ta lalace. Abun birgima yana sanya matsi mafi girma anan, yana haifar da saurin lalacewa da bawon ƙarfe na hanyar tseren zobe. Rolling bearing wani sashe ne madaidaici, wanda ke da matukar damuwa ga al'amuran waje. A cikin tsarin kulawa, yi amfani da kyalle mai tsabta, wanda ba ya rufewa. Bai kamata a maye gurbin kayan shafa da tsohuwar zaren auduga ba, saboda zaren ya ƙare a cikin tsohuwar zaren auduga cikin sauƙi a haɗa shi cikin mai mai mai sannan a shiga cikin abin da ke da cutarwa. Kafin haɗawa, tsaftace jarida sosai, rami na wurin zama, da saman zobe na ciki da na waje na abin ɗaukar hoto don hana ƙazanta shiga farfajiyar auren.

③. Lalacewar da aka samu ta hanyar lalata hanyar tsere yayin shigarwa. Idan a lokacin shigarwa, ana watsa matsi da aka yi amfani da shi ta hanyar zobe na waje da ƙwallon ƙarfe, ba makawa zai haifar da ramuka a cikin ɓangaren da hanyar tseren zobe ke hulɗa da ƙwallon karfe. Girgizawa ya bare ya goge cikin kankanin lokaci. Sabili da haka, ya kamata a yi amfani da kayan aiki na musamman lokacin da ake rarrabawa, kuma sassan da ke da karfi ya kamata su kasance daidai kuma har ma.

4. Ragewar radial da axial na haɓaka yana ƙaruwa

Ragewar radial da axial na bearings suna ƙaruwa, sai dai bushewar juzu'i da wuce gona da iri da lalacewa yayin farawa. Yawanci yana faruwa ne sakamakon takun saka tsakanin barbashi na ƙarfe a saman sassan da yashi, ƙura da datti a cikin man mai a kan abubuwan birgima da hanyoyin tsere.

Ƙaƙwalwar yana da haɓaka mai mahimmanci a cikin sharewa tsakanin zobe da abubuwa masu birgima saboda lalacewa mai lalacewa, an samar da saman matte akan titin tsere, kuma alamun da ba su dace ba sun bayyana. Hanyar rigakafin ita ce maye gurbin man mai a kan lokaci, kuma ramin mai ya kamata ya zama iska don hana shigar da datti.
