Tishli g’ildiraklarning geometrik parametrlarini aniqlaymiz. Bo’luvchi aylanalari radiuslari:


π‘Ÿ1 = 0,5 βˆ™ π‘š βˆ™ 𝑧4 = 0,5 βˆ™ 22 βˆ™ 5 = 55π‘šπ‘š


π‘Ÿ2 = 0,5 βˆ™ π‘š βˆ™ 𝑧5 = 0,5 βˆ™ 40 = 75 π‘šπ‘š
Asosiy aylanalarning radiuslari:

π‘Ÿπ‘1 = π‘Ÿ1 βˆ™ π‘π‘œπ‘ 20Β° = 70 βˆ™ 0,93 = 51.15 π‘šπ‘š;


π‘Ÿπ‘2 = π‘Ÿ2 βˆ™ π‘π‘œπ‘ 20Β° = 100 βˆ™ 0,93 = 69.75 π‘šπ‘š;
G’ildirak tishlarining balandligi:


π‘Ž
β„Ž4 = β„Ž5 = π‘š(2 βˆ™ β„Žβˆ— + 𝑐0) = 5 βˆ™ (2 βˆ™ 1 + 0,25) = 11,25 π‘šπ‘š


Ilashmaning boshlang’ich aylana yoyi bo’yicha qadami:

𝑃 = πœ‹ βˆ™ π‘š = 3,14 βˆ™ 5 = 15,7 π‘šπ‘š


Tishning boshlang’ich aylana yoyi bo’yicha qalinligi

𝑆4 = 𝑆5 = 0,5 βˆ™ 15,7 = 7,85 π‘šπ‘š


G’ildirak tishlarining botiqligi aylanasi (ichki aylana) radiuslari:

19

π‘Ÿπ‘“1 = π‘Ÿ1 βˆ’ π‘š βˆ™ (1 + 𝑐0) = 55 βˆ’ 5 βˆ™ (1 + 0,25) = 48.75 π‘šπ‘š;


π‘Ÿπ‘“2 = π‘Ÿ2 βˆ’ π‘š βˆ™ (1 + 𝑐0) = 75 βˆ’ 5 βˆ™ (1 + 0,25) = 68.75 π‘šπ‘š;
G’ildirak tishlarining tashqi aylanasi radiuslari:

π‘Ÿπ‘Ž1 = π‘Ÿπ‘“1 + β„Ž4 = 63,75 + 11,25 = 60 π‘šπ‘š;


π‘Ÿπ‘Ž2 = π‘Ÿπ‘“2 + β„Ž5 = 93,75 + 11,25 = 80 π‘šπ‘š;
Galtelning yumaloqlanish radiusi

π‘Ÿπ‘ = 0,4 βˆ™ π‘š = 0,4 βˆ™ 5 = 2 π‘šπ‘š


O’qlararo masofa

π‘Žπ‘€ = 0,5π‘š(𝑧1 + 𝑧2) = 0,5 βˆ™ 5 βˆ™ (28 + 40) = 130 π‘šπ‘š
