6.6 Tishli g’ildirakning konstuktiv o’lchamlari.
Bo’luvchi diametr – d_i=m*z
Tashqi diametr – d_ai=d_i+2m
Ichki diametr – d_fi=d_i-2.5m
Vallar orasidagi masofa – A_w=(d_k+d_sh)/2.

Shponka tanlash:
Qo`shimcha val uchun
Val diametri d=32 ga mos shponka razmerlarini jadvaldan tanlab olamiz
b=10
L=22 … 110
1-val uchun
Val diametri d=34 ga mos shponka razmerlarini jadvaldan tanlab olamiz
b=10
L=22 … 110
3-val uchun
Val diametri d=61 ga mos shponka razmerlarini jadvaldan tanlab olamiz
b=18
L=50 … 200
