Rolikli zanjir uchun to'g'ri qadamni qanday tanlash mumkin?

Hisoblangan quvvatni olish uchun uzatiladigan quvvatni xizmat koeffitsientiga ko'paytiring. Kichik tishli g'ildirak tezligiga ko'ra quvvat jadvallaridan zanjir qadamini toping. Keng tarqalgan qadamlar: 08B (12,7 mm) — yengil yuk uchun, 10B (15,875 mm) — o'rta yuk uchun, 12B–16B — og'ir yuk uchun.

Zanjirli uzatmalarda qanday xizmat koeffitsientlari qo'llaniladi?

Xizmat koeffitsientlari: 1,0 — tekis yuk/yumshoq ishga tushirish; 1,3 — o'rtacha zarba; 1,5 — kuchli zarba; 1,7 — tez-tez ishga tushirish/teskari aylantirish. Kuniga 16 soat va undan ko'p ishlashda 1,25 ga ko'paytiring.

Zanjir uzunligini bo'g'inlarda qanday hisoblash mumkin?

Chain length L = 2C/p + (z1+z2)/2 + [(z2-z1)/(2π)]²×p/C, where C is center distance, p is pitch, z1 and z2 are sprocket teeth. Round to the nearest even number of links.

Zanjirning maksimal tezligi qancha?

Zanjirning maksimal tezligi uning sifati va moylanishiga bog'liq. Odatdagi chegaralar: 08B — 12 m/s gacha, 10B — 15 m/s gacha, 12B — 18 m/s gacha. Yuqori tezliklarda yog' vannasi yoki bosimli moylash talab etiladi.

Tishli g'ildirakning minimal tish soni qancha?

Tavsiya etilgan minimum: silliq ishlash uchun 17 tish, yuqori tezlik uchun 21 tish. Kam tish soni yeyilish, shovqin va akkordli ta'sirning ortishiga olib keladi. Standart minimum 9 tish, ammo quvvat uzatish uchun tavsiya etilmaydi.

Zanjirli uzatma kalkulyatori

Quvvat jadvallaridan rolikli zanjir qadamini tanlang. Quvvat, haydovchi/haydalanadigan tezlik va xizmat koeffitsientini kiriting. Zanjir tezligi, tishli g'ildirak o'lchamlari va zanjir uzunligini hisoblab beradi.

Chain Power Rating Table (single strand, 19T sprocket — typical manufacturer catalogue values)

Chain	Pitch	@500 RPM	@1000 RPM	@1500 RPM
06B-1	9.525 mm	1.1 kW	1.8 kW	2.3 kW
08B-1	12.70 mm	2.8 kW	4.7 kW	6.0 kW
10B-1	15.875 mm	5.3 kW	9.0 kW	11.5 kW
12B-1	19.05 mm	8.9 kW	15 kW	19 kW
16B-1	25.40 mm	19 kW	32 kW	38 kW
20B-1	31.75 mm	33 kW	52 kW	60 kW
24B-1	38.10 mm	55 kW	85 kW	95 kW

⚠️ Note: Power ratings, service factors and strand multipliers are engineering estimates based on manufacturer catalogue practice — ISO 606 specifies chain dimensions, tolerances and minimum breaking loads, not power ratings. Ratings are approximate and depend on lubrication type. For duplex chains, multiply by 1.7; for triplex by 2.5. Always verify against the selected chain manufacturer’s catalogue.
