Mene ne taron bearings na crankshaft na mota?
Haɗakar bearings na crankshaft na mota wani ɓangare ne da aka sanya a kan maƙallin da aka gyara na crankshaft da bulo na silinda na injin mota, wanda galibi yana aiki don ɗaukar kaya da kuma shafa mai. Yawanci ya haɗa da nau'i biyu: bearings da flanged bearing shells. Flanged bearing shells ba wai kawai zai iya tallafawa da kuma shafa mai na crankshaft ba, har ma ya sanya crankshaft ɗin a tsaye, yana sa tsarin injin ya fi karko .
Aikin haɗakar bearings na crankshaft
Youdaoplaceholder0 Tallafi da Man Shafawa : Haɗa bearings na crankshaft, ta hanyar ƙirarsa ta musamman, zai iya tallafawa crankshaft yadda ya kamata kuma ya tabbatar da kwanciyar hankali da dorewarsa yayin aiki mai sauri. A halin yanzu, man shafawa yana samar da fim ɗin mai tsakanin crankshaft da kuma bearing bushi, yana rage gogayya da lalacewa.
Youdaoplaceholder0 Rage gogayya da asara : Haɗawar bearing na crankshaft yana rage asarar kuzari ta hanyar rage gogayya kai tsaye tsakanin crankshaft da toshewar silinda, ta haka yana haɓaka inganci da tsawon rayuwar injin.
Matsayin Youdaoplaceholder0 da kwanciyar hankali : Dajin mai lankwasa ba wai kawai yana tallafawa shaft ɗin crankshaft ba ne, har ma yana sanya shi a kan alkiblar axial, yana tabbatar da daidaito da daidaiton shaft ɗin crankshaft yayin aiki.
Kayan aiki da hanyoyin masana'antu na haɗakar bearings na crankshaft
An yi amfani da kayan ƙarfe wajen haɗa bearing na crankshaft. Kayan da aka fi amfani da su sun haɗa da:
Youdaoplaceholder0 ƙarfe mai ƙarfe : Yana da kyakkyawan juriyar lalacewa, juriyar zafi da kuma juriyar gajiya.
Youdaoplaceholder0 aluminum gami : Yana da laushi mai sauƙi da juriya ga tsatsa, wanda hakan ya sa ya dace da injunan da ke da aiki mai yawa da kuma nauyi.
Youdaoplaceholder0 ƙarfe gami : Yana da ƙarfi mai ƙarfi da juriya ga lalacewa, kuma ya dace da takamaiman yanayi na aikace-aikace.
Youdaoplaceholder0 ƙarfe : ana amfani da shi a cikin injunan da ke da babban aiki don biyan buƙatun aiki mafi girma da dorewa .
Babban aikin haɗa bearings na crankshaft na mota shine tallafawa da gyara crankshaft, tabbatar da cewa crankshaft ba zai lalace ba yayin aiki mai sauri. Bakin bearings na crankshaft suna samar da fim ɗin mai tsakanin crankshaft da bearings, wanda ke hana hulɗa kai tsaye tsakanin su biyun, ta haka ne rage gogayya da lalacewa da kuma tsawaita rayuwar crankshaft .
Bugu da ƙari, bearings na crankshaft suna da ayyuka masu zuwa:
Youdaoplaceholder0 Rage gogayya da lalacewa : Fim ɗin mai tsakanin bearing ɗin crankshaft da crankshaft na iya rage gogayya yadda ya kamata, ta haka ne zai tsawaita rayuwar crankshaft ɗin. Idan fim ɗin mai ya karye, hulɗa kai tsaye tsakanin bearing ɗin da crankshaft zai haifar da mummunan lalacewa da ƙonewar bearing .
Youdaoplaceholder0 Rage hayaniya : Saboda babban yankin hulɗa tsakanin daji mai ɗaukar kaya da kuma crankshaft, matsakaicin matsin lamba yana da yawa, kuma tasirin mai na fim ɗin mai yana sa aikin ya yi laushi kuma hayaniyar ta ragu.
Youdaoplaceholder0 yana ba da digiri na 'yanci na axial : lokacin da injin ke aiki, crankshaft zai faɗaɗa saboda zafi kuma ya samar da wani motsi a cikin alkiblar axial. Harsashin bearing yana ba da damar wannan motsi, yayin da bearing ɗin ball na iya haifar da lalacewa mara daidaituwa da lalacewa da wuri .
Youdaoplaceholder0 Saurin wargaza zafi : Yankin da ke tsakanin bishiyar bearing da crankjournal yana da girma, kuma man injin yana ci gaba da zagayawa don shafawa, wanda zai iya cire zafi mai yawa da sauri kuma yana da amfani ga wargaza zafi na injin .
Waɗannan ayyukan bearing ɗin crankshaft tare suna tabbatar da aiki mai kyau da kuma amincin injin na dogon lokaci.
Babban dalilan da ke haifar da matsala a cikin haɗa bearing na crankshaft na motoci sun haɗa da waɗannan:
Youdaoplaceholder0 Rashin shafa man shafawa : Rashin isasshen man shafawa ko lalacewarsa, lalacewar famfon mai, fashewar bututun mai, da sauransu duk na iya haifar da raguwar matsin lamba na mai, wanda ke haifar da rashin kyawun man shafawa, gogayya ta gida da yawa, da kuma lalata bearing ɗin crankshaft .
Youdaoplaceholder0 Daidaitaccen daidaitawa : Idan daidaiton daidaitawa tsakanin shaft da daji mai ɗaukar kaya ya yi ƙanƙanta ko ya yi yawa, zai shafi tasirin shafawa, ƙara gogayya, kuma don haka zai lalata bearing ɗin crankshaft .
Youdaoplaceholder0 Kutsewar Abrasive : Abubuwan da ke lalata fata kamar ƙura da abrasive na ƙarfe suna mamaye saman ƙarfe na littafin rubutu da kuma daji mai ɗauke da ƙwayoyin cuta, suna haifar da ƙaiƙayi da lalacewa marasa kyau.
Amfani da mara kyau: kamar fara sanyi a yanayin zafi mai ƙarancin yawa, tsawaita aiki, da kuma kashe injin kai tsaye bayan aiki mai nauyi na dogon lokaci, da sauransu, duk suna iya haifar da lalacewa ga bearing ɗin crankshaft .
Matsalar Haɗawa ta Youdaoplaceholder0 : Zaɓin harsashin bearing mara kyau wanda bai dace da abin hawan asali ba na iya haifar da lalacewa ga harsashin crankshaft .
Matakan kariya da gyara na Youdaoplaceholder0 sun haɗa da:
Youdaoplaceholder0 A riƙa duba matakin man shafawa : A tabbatar cewa man shafawa ya isa kuma yana da inganci mai kyau, kuma a riƙa canza shi akai-akai don guje wa amfani da man shafawa mara kyau .
Youdaoplaceholder0 Daidaita izinin dacewa : Tabbatar cewa izinin dacewa tsakanin sandar da kuma daji mai ɗaukar kaya yana cikin iyaka mai dacewa (galibi 0.08-0.10mm).
Youdaoplaceholder0 Daidaitaccen farawa da aiki : Idan ana farawa a lokacin hunturu, da farko a juya crankshaft sau da yawa. Bayan farawa, a bar shi ya yi aiki har sai zafin ruwan ya tashi sama da 40°C kafin a tuƙi .
Youdaoplaceholder0 A guji yin aiki na dogon lokaci da kashe injin kai tsaye bayan aiki mai nauyi : Bayan injin ya daɗe yana aiki a ƙarƙashin nauyi mai yawa, ya kamata a bar shi ya yi aiki na ɗan lokaci kafin a kashe shi .
Youdaoplaceholder0 Yi amfani da man shafawa mai inganci : Zaɓi man shafawa mai inganci, a riƙa duba ingancinsa akai-akai, sannan a maye gurbin man shafawa mai lalacewa cikin lokaci .
Ta hanyar matakan da ke sama, za a iya hana kurakurai a cikin haɗawar bearing na crankshaft na motoci yadda ya kamata, tare da tabbatar da aikin injin yadda ya kamata da kuma tsawaita tsawon lokacin aikinsa.
