Reja:

8.1. Tokarlik dasgoxini yuklama diagrammasini tuzish hamda quvvatni aniqlash.

8.2. Tokarlik dasgoxini bosh elektr yuritmasi hamda uzatish elektr yuritmasini ish rejimlari aniqlash.

Tokarlik dasgoxini bosh EY dvigatelini quvvatini hisoblash

• Kesish tezligi aniqlanadi
• Kesish kuchi hisoblanadi · ,
• Shpindeldagi momentni topiladi
• Dvigatelni statik momenti
• Kesish quvvatini hisoblanadi
• Dvigatel quvvati aniqlanadi
• Dvigatelni burchak tezligi

•  

Tenglamalardagi koeffitsientlar

• , - ishlov berish usuli va sharoitini hisobga oluvchi koeffitsientlar;
• t – kesish chuqurligi, mm;
• s – uzatma mm/ayl;
• x,y,n – daraja ko’rsatgichlari, ishlov berish usullariga bog’liq koeffitsientlar;
• T – turg’unlik koeffitsienti;
• reduktorni uzatish soni;
• reduktorni f.i.k.

•  

Uzatish mexanizmi dvigatelini quvvati

• Uzatish mexanizmini tezligi:
• Dastlabki ishlov berish vaqti:
• Stolni qaytish vaqti (salt ishlash):
• - stol tez orqaga qaytish tezligi, m/sek;
• Tozalov ishlov berish uchun ham vaqtlar yuqoridagidek aniqlanadi.
• Yuritmani tezlanish vaqti:
• Ruxsat etilgan tezlanish:
• Statik burchak tezligi:
• Ishga tushirish vaqt doyimiysi:

•
