Tishli gβildiraklarning geometrik parametrlarini aniqlaymiz. Boβluvchi aylanalari radiuslari:
π1 = 0,5 β π β π§4 = 0,5 β 22 β 5 = 55ππ
π 2 = 0,5 β π β π§ 5 = 0,5 β 40 = 75 ππ
Asosiy aylanalarning radiuslari:
ππ1 = π1 β πππ 20Β° = 70 β 0,93 = 51.15 ππ;
π π2 = π 2 β πππ 20Β° = 100 β 0,93 = 69.75 ππ;
Gβildirak tishlarining balandligi:
π
β4 = β5 = π(2 β ββ + π0) = 5 β (2 β 1 + 0,25) = 11,25 ππ
Ilashmaning boshlangβich aylana yoyi boβyicha qadami:
π = π β π = 3,14 β 5 = 15,7 ππ
Tishning boshlangβich aylana yoyi boβyicha qalinligi
π4 = π5 = 0,5 β 15,7 = 7,85 ππ
Gβildirak tishlarining botiqligi aylanasi (ichki aylana) radiuslari:
19
ππ1 = π1 β π β (1 + π0) = 55 β 5 β (1 + 0,25) = 48.75 ππ;
ππ2 = π2 β π β (1 + π0) = 75 β 5 β (1 + 0,25) = 68.75 ππ;
Gβildirak tishlarining tashqi aylanasi radiuslari:
ππ1 = ππ1 + β4 = 63,75 + 11,25 = 60 ππ;
ππ2 = ππ2 + β5 = 93,75 + 11,25 = 80 ππ;
Galtelning yumaloqlanish radiusi
ππ = 0,4 β π = 0,4 β 5 = 2 ππ
Oβqlararo masofa
ππ€ = 0,5π(π§1 + π§2) = 0,5 β 5 β (28 + 40) = 130 ππ
