Xulosa
Men usbu 6П80Г tezliklar qutisini loyihashda avvalo, berilgan qiymatlari boyicha asosiy kinematik parametrlarni hisobladim, kegin unga struktura setkasi va aylanishlar chastata grafigini tuzdim. So‘ng elektro dvigatelni hisoblab topdim. Undan keyin tezliklar uzatmasi qutisini konstruktiv o‘lchamlarini aniqladim va mustahkamlikga hisobladim. Shundan so’ng topilgan qiymatlari yordamida AutoCAD dasturida uzatmalar qutisini chizmasini chizdim.

Bugungi kunda yurtimizda texnika sohasi juda shiddat bilan taraqqiy etmoqda. Barcha sohalar kabi texnika sohasi ham yurtda qanchalik yaxshi rivojlansa shu yurtda ishlab chiqarish yanada o‘sadi va rivojlanadi.

Shuning uchun biz yoshlar ham o‘z sohamizni yanada chuqurroq o‘rganishimiz lozim. Buning uchun esa yaratilayotgan imkoniyatlardan to‘laqonli foydalanib o‘z ustimizda yanada ko‘proq ishlashimiz va horijiy dastgohlar, ularninng tuzilishi, ishlab chiqarish harakteristikalari bilan ko’proq tanishib borishimiz lozim. Buning uchun esa albatta chet tillari borasida ko‘nikmamizni yanada oshirsak maqsadga muvofiq bo‘ladi.
