Mụta maka ụkpụrụ radial clearance maka rolling bearings

BịaNhagharị na-ezo aka n'otú ihe si aga mgbe a naghị etinye ihe na-aga n'ime ogwe ma ọ bụ igbe ihe na-aga, otu akụkụ nke mgbanaka dị n'ime ma ọ bụ mgbanaka mpụta na-edozi, wee gaa n'akụkụ nke na-aga n'ihu n'akụkụ ma ọ bụ n'akụkụ. Dịka ntụziaka nke ihe na-aga, enwere ike kewaa ya n'ụzọ radial clearance na axial clearance. Nhagharị dịkwa oke mkpa maka iji ihe na-aga n'ihu.

Nkwụsị radial nke bearing na-agagharị bụ nkezi mgbakọ na mwepụ nke anya radial nke mgbanaka mpụta ma e jiri ya tụnyere mgbanaka dị n'ime site na otu ọnọdụ oke radial eccentric ruo na ọnọdụ oke dị iche na steeti anaghị ebu ibu. Dịka ọkọlọtọ mba GB/T307.1-2018 si dị, a na-ekewa radial clearance n'ime ọkwa ise: nnukwu, ọkara, obere, obere na obere. Uru nhicha nke oke ọkwa ọ bụla bụ ndị a: C2, CN, C3, C4, C5; C0, C1, C2, CN; Obere maka C0, C1, C2, CN; Nke kacha nta bụ C0 na C1; Ndị pere mpe bụ C0 na C1, ebe C0 na-anọchite anya obere nhazi ebe C5 na-anọchite anya nnukwu nhazi.

 

Tinyere nke ahụ, ọkọlọtọ ISO na ọkọlọtọ ABMA nke America nwekwara akara dị iche iche maka radial clearance. E kewara ọkọlọtọ ISO n'ime akara anọ: N, P, M, na K, a kewara ọkọlọtọ ABMA nke America n'ime akara ise: C1, C2, C3, C4, na C5. Mgbe ị na-ahọrọ bearings, ọ dị mkpa ịkọwapụta ihe eji achọpụta klas clearance.
