Podshipnikni demontaj qilish kuchi qanday hisoblanadi?

The removal force F = p × π × d × L × μ, where p is the interface pressure from Lamé's equations, d is the bore diameter, L is the contact length, and μ is the friction coefficient (typically 0.10-0.20 for steel-on-steel).

Podshipnikni demontaj qilishda ishqalanish koeffitsientining odatiy qiymati qanday?

For dry steel-on-steel: μ ≈ 0.12-0.18. With oil: μ ≈ 0.05-0.10. For removal (vs. assembly), friction is generally higher because there is no oil film, and microwelds may have formed.

Demontaj kuchini qanday kamaytirish mumkin?

Tashqi halqani (yoki uyani) kengaytirish uchun isiting yoki milni sovuting. Ariqcha orqali yog' yuborish gidravlik bo'shatish effektini berishi mumkin. Maxsus podshipnik tortuvchi moslamalar kuchni bir tekis taqsimlaydi.

Qanday siqilish o'lchami qanday bosimga olib keladi?

0,020 mm siqilish o'lchamiga ega 50 mm po'lat mil uchun kontakt bosimi taxminan 30–50 MPa ni tashkil etadi. Bu odatiy podshipnik kengliklari uchun bir necha kN demontaj kuchini hosil qiladi.

Demontaj qilingan podshipnikni qayta ishlatish mumkinmi?

Tegishli asboblar (tortuvchi moslamalar, gidravlik usullar) yordamida ehtiyotkorlik bilan chiqarilgan podshipniklar ko'pincha qayta ishlatilishi mumkin. Podshipnikni hech qachon bolg'a bilan urmanman. Demontajdan so'ng yugurish yo'llarida shikast izlari borligini tekshiring.
