Bilyali vintning qo'rg'oshi, shuningdek, qadam deb ataladi, ya'ni pitch vintining bir aylanish uchun chiziqli harakati masofasi. Umumiy qo'rg'oshin diapazonlari 1, 2, 4, 6, 8, 10, 16, 20, 25, 32, 40. Kichik va o'rta qo'rg'oshinli dog'lar odatda faqat 5 va 10 ga ega, yirik qo'rg'oshin mahsulotlari esa 1616, 2020, 2525, 3232, 4040 (birinchi ikkita raqam diametri, oxirgi ikkitasi esa etakchi). Moviy muzning texnik xususiyatlari uchun monomer ishlab chiqarishga qarang. Etakchi chiziqli tezlik bilan bog'liq. Kirish tezligi doimiy bo'lsa, qo'rg'oshin qanchalik katta bo'lsa, tezlik tezroq bo'ladi. Lanbing taklifi: 5 va 10 ta yetakchini tanlashga harakat qiling.
The selected lead is related to the required movement speed and system, usually from 4, 5, 6, 8, 10, 12, 20. The size is larger, the lead can also be larger (mainly consider the bearing tooth thickness). When meeting the speed requirements, generally choose a smaller lead (conducive to improving the control accuracy); for high-speed occasions, the lead can be greater than 20; for the ground screw, the lead can be approximately equal to the nominal diameter (under grinding The limit of the helix angle), such as 32 (3232), 40 (4040), of course, it can be larger (non-grinding, but rarely considered). Under the same conditions, the larger the lead, the larger the rotating part, the larger the period error, and the faster the speed. Therefore, flexibility is required at high speeds, and abandoning part of the accuracy requirements will make the gap requirements less significant (increased lead accuracy deviation). Therefore, the large screw is generally a single nut.
Pitch - bu ikkita qo'shni iplar orasidagi masofa. Pitch va qo'rg'oshin bir-biriga bog'liq, ammo ekvivalent tushunchalar emas. Ko'p odamlar maydoncha va etakchini chalkashtirib yuborishadi. Qo'rg'oshin tushunchasi vint yoki gaykaning bir marta aylanishidan so'ng gayka vint ustida harakatlanadigan masofani bildiradi. Agar u bitta-bolli vint bo'lsa, qadam va qo'rg'oshin bir xil bo'ladi. Ko'p boshli sharli vintlar- bo'lsa, qo'rg'oshin=qadami vint boshlari soniga ko'paytiriladi. Agar vint aylanishda to'rtta (yoki beshta) vintni harakatlantirsa, bu vint to'rt{3}}yivli (yoki besh{4}}simli) vint ekanligini bildiradi, bu odatda to'rt-bosh deb nomlanadi. (yoki besh{6}}boshli) vint.
