Nkọwa edemede:
I. The Thermodynamic basic tiori na-etinye aka na igwe na-ebelata okpomọkụ: Ngwa nke ụkpụrụ nke mgbasawanye ọkụ na nkwekọrịta na njigide ngwá ọrụ.
1. Key Data na Sayensị ihe:
Alloy thermal coefficient nke njide:
Ngwá ọrụ na-ekpo ọkụ na-ekpo ọkụ ígwè: α ≈ 11 × 10⁻⁶ / ℃ (na-agbasa site na 0.33mm mgbe okpomọkụ na-ebili site na 300 ℃)
Ihe njide alloy siri ike: α ≈ 5 × 10⁻⁶ / ℃
Nhazi dabara adaba:
ΔD=D0 . α. ΔT
Ọmụmaatụ: The φ10mm ngwá ọrụ aka na-ekpo ọkụ na 300 ℃ → The oghere gbasaa site 0.033mm → Mgbe obi jụrụ.

2.Comparison nke Uru nke Teknụzụ igwe na-ebelata okpomọkụ:
| Usoro njigide | Dayameta Runout | Mbufe Torque | Ugboro ngwa |
| Jide Fit Fit | ≤3 | ≥100 | 50,000+ |
| Ihe njide akụrụngwa hydraulic | ≤5 | 400-600 | 35,000 |
| ER mmiri mkpokọta | ≤10 | 100-200 | 25,000 |
II. Usoro arụ ọrụ ọkọlọtọ maka igwe na-ebelata okpomọkụ

III. Ntuziaka nlekọta miri emi maka igwe na-ebelata okpomọkụ: Site na nlekọta kwa ụbọchị nke igwe shrink Fit ruo amụma mmejọ.
1.Maintenance Schedule maka isi ihe nke Shrink Fit Machine
| Ngwa igwe dabara adaba | Nlekọta kwa ụbọchị | Nchekwa oke | Mmegharị kwa afọ |
| Igwe ọkụ ọkụ | Wepu nha oxide | Nleta uru nguzogide(ngbanwe na-erughị ma ọ bụ hà nhata 5%) | Dochie uwe mkpuchi seramiiki |
