BIR CHO‘MICHLI EKSKAVATORLAR PO‘LAT SIM ARQONLARINI DOIMIY MOYLASH TIZIMINI ISHLAB CHIQISHNI ILMIY ASOSLASH
Аннотация
Mazkur maqolada EKG-10 turidagi bir cho‘michli karyer ekskavatorlarida qo‘llaniladigan ko‘tarish po‘lat sim arqonlarining ishlash sharoiti, ishqalanish jarayonlari va yeyilish intensivligi tahlil qilingan. Ekspluatatsiya jarayonida po‘lat sim arqonlar yuqori tortish kuchlari, dinamik yuklanishlar, tashqi muhit ta’siri hamda yetarli moylanmaslik natijasida tez yeyilishi aniqlangan. Ayniqsa, ko‘tarish bloklari va bosh shkivlar orqali harakatlanish vaqtida simlar orasida ichki ishqalanish kuchlari ortishi natijasida mahalliy qizish, metall charchashi va sim tolalarining uzilishi sodir bo‘lishi kuzatildi. Tadqiqot davomida po‘lat sim arqonlarni moylashning to‘rt xil holati, yangi moylangan, kam moylangan, moylanmagan va davriy ravishda tomchilatib moylanadigan holatlari qiyosiy tahlil qilindi. SolidWorks Simulation dasturi yordamida arqonda hosil bo‘ladigan kuchlanishlar, kontakt bosimi, ishqalanish koeffitsiyenti va yeyilish zonalari raqamli modellashtirildi. Tahlil natijalariga ko‘ra, moylanmagan holatda ishqalanish koeffitsiyenti 0,25 gacha oshishi, yeyilish intensivligi esa 3–4 barobar ortishi aniqlandi. Davriy tomchilatib moylash usuli qo‘llanilganda esa ishqalanish koeffitsiyenti 50–60 % ga kamayishi, yeyilish jarayonining sezilarli pasayishi hamda arqon xizmat muddatining 40–70 % gacha uzayishi kuzatildi. Shuningdek, maqolada ko‘tarish arqonlari uchun avtomatik tomchilatib moylash tizimining konstruktiv sxemasi taklif qilinib, uning ishlash prinsipi, texnik parametrlari va ekspluatatsion samaradorligi baholandi. Olingan natijalar asosida doimiy moylash tizimini joriy etish ekskavatorning ishonchliligi, texnik tayyorgarlik koeffitsiyenti va umumiy ish unumdorligini oshirishga xizmat qilishi ilmiy jihatdan asoslab berilgan.
