2.3. Reduktorni slindrimon uzatmasining loyiha xisobi.
Reduktorni slindrimon uzatma g’ildiraklarini tayorlash uchun material tanlanib, ularga termik ishlov berish turi belgilanadi.
Shesternya uchun po’lat 40X, termik ishlov berish turi yaxshilangan, qatiqqlik HB 230; g’ildirak uchun 40X, termik ishlov berish turi yaxshilangan, qatiqqlik HB 200.
Tishli uzatmalarda shesternya va g’ildiraklarning mustahkamligini kantakt kuch-lanish bo’yicha, bir xil qilib tayorlash murakkab bo’lganligi uchun, mustahkamlikni chegaralovchi tishli g’ildirak tanlab olinadi. Ishlash muddatini xisobga oluvchi koeffitsent K_HL=1.0 bo’lsa, ruxsat etilgan kantakt kuchlanish g’ildirakt uchun aniqlanib, mustahkamlik shunga asosan tekshiriladi.
