BOLLARNI BOShQARISh-BOSHQARISH

Nozik bilya rulmanlari ABMA halqali rulman muhandislari qo'mitasiga (ABEC) muvofiq baholanadi. Toleranslar ABEC darajalari o'rtasidagi asosiy farq qiluvchi omil hisoblanadi (masalan, ABEC-5 rulmanlari ABEC-1 ga qaraganda qattiqroq toleranslarga ega. Shuningdek, biz PO boshlanadigan ISO rulman bardoshligini qo'llaymiz. P6. P5, keyin P4.


Izoh: ABEC va ISO Rulman standartlari, asosan, bardoshlik bardoshliligi bilan bog'liq. Bu radial o'ynashga ta'sir qilmaydi. toleranslarning yaxshilanishi kamroq o'yin bilan rulman hosil qiladi deb ba'zan noto'g'ri o'ylashadi. Shaft va korpus rulman bilan bir xil toleranslarda ishlab chiqarilgan deb taxmin qilsak, rulmaning yuqori toleranslari shaft / korpus va rulman o'rtasida yaxshi juftlikni hosil qiladi,


Taqqoslash jadvali ma'lumot uchun quyidagicha tuzilgan!
