Dziwani zambiri za miyezo yowunikira ma radial ya ma bearing ozungulira

KunyamulaKuchotsa mphamvu kumatanthauza kuchuluka kwa kayendedwe pamene chotengera sichinakhazikitsidwe mu shaft kapena bokosi loperekera mphamvu, mbali imodzi ya mphete yamkati kapena mphete yakunja imakhazikika, kenako mbali yomwe siili yokhazikika imasuntha mozungulira kapena mozungulira. Malinga ndi momwe kayendedwe kakuyendera, ikhoza kugawidwa m'magawo awiri: chochotsera mphamvu ya radial ndi chochotsera mphamvu ya axial. Kuchotsa mphamvu ya radial ndikofunikira kwambiri pakugwiritsa ntchito ma bearing.

Kutuluka kwa radial kwa chogwirira chozungulira ndi chiwerengero cha mawerengedwe a mtunda wa radial wa mphete yakunja poyerekeza ndi mphete yamkati kuchokera pamalo amodzi ozungulira a radial kupita kumalo ena otsutsana ndi malire omwe sanapatsidwe kale. Malinga ndi muyezo wadziko lonse wa GB/T307.1-2018, kutuluka kwa radial kumagawidwa m'magulu asanu: lalikulu, lapakati, laling'ono, laling'ono kwambiri komanso laling'ono kwambiri. Mitengo yotuluka ya giredi iliyonse ndi iyi: C2, CN, C3, C4, C5; C0, C1, C2, CN; Yaing'ono ya C0, C1, C2, CN; Yocheperako ndi C0 ndi C1; Yowonjezera yaying'ono ndi C0 ndi C1, pomwe C0 imayimira malo ochepa ndipo C5 imayimira malo akuluakulu.

 

Kuphatikiza apo, muyezo wa ISO ndi muyezo wa American ABMA ulinso ndi magiredi osiyanasiyana a radial clearance. Muyezo wa ISO umagawidwa m'magiredi anayi: N, P, M, ndi K, ndipo muyezo wa American ABMA umagawidwa m'magiredi asanu: C1, C2, C3, C4, ndi C5. Posankha ma bearing, ndikofunikira kufotokoza zomwe zimagwiritsidwa ntchito podziwa kalasi ya clearance.

 

Kutuluka kwa radial kwa bearing kumakhudza mwachindunji nthawi yake yogwirira ntchito, kukwera kwa kutentha, phokoso ndi kugwedezeka ndi zina. Kutuluka kwakukulu kungayambitse moyo wa bearing waufupi, kuchepa kwa kulondola kozungulira, kugwedezeka ndi phokoso; Ngati kutuluka kuli kochepa kwambiri, n'zosavuta kuyambitsa kukangana ndi kutentha kuwonjezeka, kukwera kwa kutentha kuwonjezeka, komanso kumabweretsa kutseka kwa bearing. Chifukwa chake, posankha kutuluka kwa bearing, ndikofunikira kuganizira kulimba kwa bearing ndi shaft, kusiyana kwa kutentha komwe kumachitika chifukwa cha ntchito ya bearing, komanso kusiyana kwa expansion coefficient ya bearing ndi shaft.
