1-TAJRIBA MASHG’ULOTI
TIKUV MASHINALARI DETALLARINING SHARTLI BELGILARI
Ishni bajarish tartibi:
Mashina detallarining turlari va vazifalari haqida tushunchaga ega bo’lish
Mashina detallari vazifasiga ko‘ra turlariga doir ma’lumotlar bilan tanishish
Mashina – bu foydali ish bajaruvchi mexanizm yoki mexanizmlar kompleksi. Masalan, transport mashinasi, texnоlogik mashinalar, hisoblash mashinalari. Mexanizm – detallardan tashkil topgan birikmadir. Detal deb, ma’lum maqsad uchun ishlab chiqarilgan qattiq jismga aytiladi. Mashina detallari asosan metallardan, ba’zan plastmassa, rezinadan tayyorlanishi mumkin. Mashina detallari tuzilishi jihatidan ikkiga bo‘linadi:
1) standart detallar;
2) maxsus detallar.
Standart detallar (1.1-rasm) hamma mashinalarda uchraydi, ular ma’lum o‘lchamlarda ishlab chiqariladi. Masalan, bolt – 1, shayba – 2, gayka – 3, shpilka – 4, vint – 5, vtulka – 6, vintlar – 7 va boshqalar.
Maxsus detallar ma’lum tiрdagi mashinalar uchun alohida ishlab chiqariladi (1.2-rasm). Masalan, tepki – 1, tishli reyka – 2, shatun – 3, kulachok – 4, krivoshiр – 5, koromislo – 6, vilka – 7 va boshqalar.
