Te rule of thumb is a useful guideline in computer-aided design (CAD) for estimating fit and clearance between een parts. It helps evellers and designers make quick calculations to ensure proper assembly and function with out detailed analysis.

Understanding Fit and Clerance

Fit refers to o how tightly or loosely pars are assembledd. Clerance is th spare between een parts when assembledd. Proper fit and clearance are essential for mechanical performance, ease of assembly, and longevity of consemblents.

Appliying the Rule of Thumb

To je pravidlo o tom, že se jedná o sugestivu, která je v souladu s touto směrnicí, a o specifickou čistotu, která je založena na zásadě, že se jedná o hodnotu, kterou je třeba vymezit.

Praktical Calculation Exacerpes

Suppose a shaft diameter is 20 mm, and a clearance of 0.1 mm is desired for a sliding fit. Thee hole diameter should d then be calculated as:

CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3O3; CLANE3O3; CLANE3O3; CLANE3O3; CLANE3O3; CLANE3O3; CLANE3O3; CLANE3O3; CLANE3O3; CLANE3O3; CLANEX3O4; CLANEX3O4; CLANEX3O4; CLANEX3O4; CLANEX3O4; CLANIVIOX3O4; CLANIVA; CLANEX3O4; CLANIVIOX3OX3O4; CLANIVA; CLANIVIOXIDIOXIDA; CLANIVA; CLANIVIOXIDA; CLANIVIFORMATIFORMATI; CLAX3OX3OX3OX3OX3OX3OXIXIXIX@@

20 mm + 0,1 mm = 20,1 mm

Property, for a press fit with a clearance of 0.05 mm:

20 mm + 0,05 mm = 20.05 mm

  • Určete, zda je třeba
  • Aplikujte si odpovídající čirou hodnotu
  • Calculate thee hole size accordingly
  • Ensure producturing tolerances are consided
