Angular Contact Ball Bearings: Yambitsani Kuzungulira Kolondola Pansi pa Katundu Wapamwamba

Angular contact bearings, mtundu wa mpira wokhala mkati mwa mayendedwe ogudubuza, amapangidwa ndi mphete yakunja, mphete yamkati, mipira yachitsulo, ndi khola. Mphete zonse zamkati ndi zakunja zimakhala ndi mipikisano yothamanga yomwe imalola kuti axial asamuke. Ma bere awa ndi oyenera kunyamula katundu wophatikizika, kutanthauza kuti amatha kutengera mphamvu zama radial ndi axial. Chinthu chofunika kwambiri ndi ngodya yolumikizirana, yomwe imatanthawuza mbali ya pakati pa mzere wolumikiza malo okhudzana ndi mpira panjira yothamanga mu ndege yozungulira ndi mzere wolunjika ku nsonga yonyamula. Kokona yokulirapo kumawonjezera kuthekera kwa chonyamulira kunyamula katundu wa axial. M'mayendedwe apamwamba kwambiri, mbali ya 15 ° yolumikizana nthawi zambiri imagwiritsidwa ntchito kuti ipereke mphamvu zokwanira za axial ndikusunga kuthamanga kwambiri.

Mzere umodzi wamakona olumikizana nawoimatha kuthandizira katundu wa radial, axial, kapena composite, koma katundu aliyense wa axial ayenera kuikidwa mbali imodzi yokha. Pamene katundu wa radial akugwiritsidwa ntchito, mphamvu zowonjezera za axial zimapangidwa, zomwe zimafuna kuti zigwirizane nazo. Pachifukwa ichi, ma bearings awa nthawi zambiri amagwiritsidwa ntchito pawiri.

Mizere iwiri yamakona olumikiziranaimatha kunyamula katundu wolumikizana ndi ma radial ndi ma bidirectional axial, pomwe ma radial katundu amakhala chinthu chachikulu, ndipo amathanso kuthandizira katundu wama radial. Kuphatikiza apo, amatha kuletsa kusamuka kwa axial mbali zonse ziwiri za shaft kapena nyumba.

Kuyika ma bearing a mpira olumikizana ndi kovutirapo kumakhala kovuta kwambiri kuposa ma berelo a mpira wakuya ndipo nthawi zambiri kumafuna kuyika kophatikizana ndikuyikanso. Ngati atayikidwa bwino, kulondola ndi moyo wautumiki wa zidazo zitha kusintha kwambiri. Kupanda kutero, sikudzalephera kukwaniritsa zolondola, koma moyo wautali wa bearing udzakhalanso pachiwopsezo.

Pali mitundu itatu yazimbalangondo za mpira: makonzedwe a msana ndi msana, maso ndi maso ndi ma tandem.
1. Kubwerera Kumbuyo - nkhope zazikulu za zitsulo ziwirizo zimatsutsana, njira yolumikizirana yolumikizira imafalikira motsatira njira ya axis of rotation, yomwe imatha kuonjezera kukhazikika kwa ma radial ndi axial support angles, ndi kuchuluka kwake. anti-deformation luso;
2. Nkhope ndi Nkhope - nkhope zopapatiza za zitsulo ziwirizi zikutsutsana, kuyanjana kwa chotengeracho kumasinthira kumayendedwe a axis of rotation, ndipo kukhwima kwa mbali yozungulira ndi yaying'ono. Chifukwa mphete yamkati ya chonyamuliracho imachokera ku mphete yakunja, pamene mphete yakunja ya zitsulo ziwirizo imakanizidwa palimodzi, chilolezo choyambirira cha mphete chakunja chimachotsedwa, ndipo kunyamulidwa kwa kunyamula kumatha kuwonjezeka;
3. Kukonzekera kwa Tandem - nkhope yaikulu ya zitsulo ziwirizo ili kumbali imodzi, mbali yolumikizana ndi yofanana ndi yofanana ndi yofanana, kotero kuti zitsulo ziwirizi zikhoza kugawana ntchito yogwira ntchito mofanana. Komabe, pofuna kuonetsetsa kuti kukhazikika kwa axial kukhazikitsidwa, awiri awiri a mayendedwe okonzedwa motsatizana ayenera kukwera moyang'anizana ndi malekezero onse a shaft. Mzere umodzi wolumikizira mpira uyenera kusinthidwa nthawi zonse motsutsana ndi chimbalangondo china cholumikizidwa mopingasa kuti chiwongolero cha shaft chiwongolere mbali ina.

Takulandilani kufunsanizambiri zobereka zokhudzana ndi mankhwala ndi njira zamakono. Kuyambira 1999, takhala tikuperekamayankho odalirikakwa opanga magalimoto ndi Aftermarket. Ntchito zopangidwa mwaluso zimatsimikizira zabwino ndi ntchito.
