Bearings na ƙwallon lamba mai layi ɗaya da layi biyu

Bearings na ƙwallon lamba na kusurwaAn haɗa su da zobe na waje, zobe na ciki, ƙwallon ƙarfe, da keji. Yana iya ɗaukar nauyin radial da na axial, kuma yana iya ɗaukar nauyin axial tsarkakakku, kuma yana iya aiki da kyau a manyan gudu. Bearings na ƙwallon hulɗa mai kusurwa ɗaya na iya jure nauyin axial kawai a hanya ɗaya. Lokacin da irin wannan bearing ɗin ke ɗauke da nauyin radial tsantsa, saboda layin nauyin abubuwan birgima da layin nauyin radial ba su cikin jirgin radial iri ɗaya ba, ana samar da ɓangaren axial na ciki, don haka dole ne a sanya shi biyu-biyu.

 

1. Bearings na ƙwallon lamba mai layi ɗaya mai kusurwa ɗaya

Bearings na ƙwallon lamba mai layi ɗaya suna da waɗannan siffofi na tsarin:

(1) Bearings na ƙwallon hulɗa mai kusurwa da za a iya rabawa

Gefen waje na wannan nau'in bearing ba shi da buɗewar kullewa, wanda za a iya raba shi da zoben ciki, keji da kuma haɗa ƙwallon, don haka za a iya sanya shi daban. Irin wannan ƙananan bearings masu diamita na ciki ƙasa da 10mm ana amfani da su galibi a cikin rotors na gyrocopic, micromotors da sauran na'urori waɗanda ke da manyan buƙatu don daidaiton motsi, hayaniya, girgiza da kwanciyar hankali.

 

(2) Bearings na ƙwallon hulɗa mai kusurwa mara rabuwa

Ramin zobe na wannan nau'in bearing yana da buɗewar makulli, don haka ba za a iya raba zoben biyu ba. Akwai nau'i uku bisa ga kusurwar hulɗa:

(1) Kusurwar hulɗa α = 40°, ta dace da ɗaukar babban nauyin axial;

(2) Kusurwar hulɗa α=25°, galibi ana amfani da ita don daidaiton bearings na spindle;

(3) Kusurwar hulɗa α=15°, galibi ana amfani da ita don manyan bearings masu daidaito.

(3) Bearings na ƙwallon hulɗa na kusurwa da aka shirya a nau'i biyu

 

Bearings na ƙwallon lamba na kusurwaAna amfani da nau'ikan bearings iri biyu don ɗaukar nauyin radial da axial, da kuma nauyin radial mai tsabta da nauyin axial a kowace hanya. Wannan nau'in bearings ana zaɓar su kuma a haɗa su zuwa nau'i biyu bisa ga wasu buƙatun da aka riga aka ɗora, kuma ana ba wa masu amfani. Lokacin da aka ɗora bearings a kan injin kuma aka matse su, za a kawar da sharewar da ke cikin bearings gaba ɗaya, kuma zobe da ƙwallon suna cikin yanayin da aka riga aka ɗora, don haka inganta tauri na bearings ɗin da aka haɗa.

 

Ana samun bearings na ƙwallon lamba na kusurwa waɗanda aka shirya su biyu-biyu a cikin tsari uku daban-daban:

(1) Tsarin baya-da-baya, lambar bayan-lambar DB, wannan tsari yana da kyakkyawan tauri, aiki mai kyau don jure wa juyawar lokaci, kuma bearing na iya ɗaukar nauyin axial mai hanyoyi biyu;

 

(2) Tsarin fuska da fuska, lambar baya ita ce DF, taurin wannan tsari da ikon jure lokacin juyawa ba su da kyau kamar tsarin DB, kuma bearing ɗin zai iya ɗaukar nauyin axial mai hanyoyi biyu;

 

(3) Tsarin tandem, lambar post-code DT, wannan tsari kuma ana iya haɗa shi a jere tare da bearings uku ko fiye a tallafi ɗaya, amma zai iya ɗaukar nauyin axial kawai a hanya ɗaya. Yawanci, domin daidaita da iyakance canjin axial na shaft, ana sanya bearing mai iya ɗaukar nauyin axial a ɗayan alkiblar a ɗayan alkiblar.

 

2. Bearings na ƙwallon lamba na layi biyu

Ana siffanta bearings na ƙwallon hulɗa a jere biyu ta hanyar ikon jure nauyin haɗin radial da axial a lokaci guda, wanda ke iyakance motsi na axial na ɓangarorin biyu na shaft.

Idan aka kwatanta da bearing ɗin ƙwallo mai tuƙi biyu, wannan nau'in bearing yana da mafi girman gudu, kusurwar hulɗa ta 32°, kyakkyawan tauri, kuma yana iya jure babban lokacin juyawa, kuma ana amfani da shi sosai a cikin cibiyar ƙafafun gaba na mota (wasu samfuran kuma suna amfani da bearing ɗin nadi mai layi biyu masu girman iri ɗaya).

 

Akwai nau'ikan tsarin guda huɗu na bearings na lamba mai layi biyu a kusurwa:

(1) Tsarin daidaitaccen bearings na Type A tare da diamita na waje ƙasa da 90mm ko daidai yake da shi. Babu ƙwallo mai tsayi, don haka yana iya jure nauyin axial daidai gwargwado a duka kwatance. An ɗauki kejin nailan 66 mai ƙarfin gilashi mai ƙarfi, kuma ƙaruwar zafin bearing ɗin ƙarami ne sosai.

(2) Tsarin da aka saba amfani da shi don bearings na Nau'in A tare da diamita na waje fiye da 90mm. Akwai maƙallin ɗaukar kaya a gefe ɗaya kuma an sanye shi da keji mai tambarin farantin ƙarfe ko keji mai tagulla.

(3) Nau'in E tsari ne mai ƙarfi, tare da maƙallin ƙwallon a gefe ɗaya, wanda zai iya ɗaukar ƙarin ƙwallan ƙarfe, don haka ƙarfin ɗaukar nauyin ya fi girma.

 

(4) Za a iya sanya beyar ƙwallon hulɗa mai kusurwa biyu a jere tare da murfin ƙura a ɓangarorin biyu da kuma ƙirar zoben hatimi nau'in A da E tare da murfin ƙura (nau'in da ba ya taɓawa) ko zoben hatimi (nau'in da aka taɓawa) a ɓangarorin biyu. Cikin beyar da aka rufe an cika shi da man lithium mai hana tsatsa, kuma zafin aiki gabaɗaya shine -30~+110°C. Ba a buƙatar sake shafawa yayin amfani ba, kuma bai kamata a dumama shi ko a tsaftace shi ba kafin shigarwa.

 

Lokacin shigar da bearings na ƙwallon hulɗa a jere biyu, ya kamata a yi taka tsantsan cewa kodayake bearing ɗin zai iya jure wa nauyin axial na bidirectional, idan akwai ramin ball a gefe ɗaya, ya kamata a yi taka tsantsan kada a bar babban nauyin axial ya ratsa ta cikin ramin da ke gefen da aka yi wa ramin.
