Je, ukubwa wa key unachaguliwa vipi?

By shaft diameter per the DIN 6885 standard lookup table (the equivalent ISO/R 773 recommendation is withdrawn).

Ni stresses zipi zinazochekwa?

Shear stress tau=F/(w*L) and bearing stress sigma=F/((h/2)*L).

Urefu gani wa key wa kutumia?

1 hadi 1.5 mara kipenyo cha shimoni. Kiwango cha chini ni urefu wa hub ukiondoa chamfers.

Je, ni nini kuhusu mkusanyiko wa mkazo?

Njia ya funguo inaunda Kt=1.5-2.5. Tumia njia za funguo zilizomaliziwa kwa ncha ili kuwa na maisha mazuri ya kuchoka.

Je, ninaweza kutumia funguo mbili?

Ndiyo kwa digrii 180. Fikiria kila moja inabeba asilimia 75 kutokana na uvumilivu.

Standard Key Sizes (DIN 6885)

Key cross-sections below follow DIN 6885. The corresponding ISO recommendation, ISO/R 773, has been withdrawn and is mentioned here for historical reference only; it listed the same sizes but is no longer a current ISO document.

Shaft d (mm)	Funguo w×h (mm)
6–8	2×2
8–10	3×3
10–12	4×4
12–17	5×5
17–22	6×6
22–30	8×7
30–38	10×8
38–44	12×8
44–50	14×9
50–58	16×10
58–65	18×11
65–75	20×12
75–85	22×14
85–95	25×14

Urefu wa funguo = 1–1.5× kipenyo cha shimoni. Angalia mkusanyiko wa mkazo katika pembe za njia ya funguo (K_t=1.5–2.5). The shear and bearing formulas above are simplified engineering checks assuming uniform stress distribution — they are common design practice, not requirements of any current ISO standard.
