Shkiv diametrlari va markazlar oralig'idan tasma uzunligini qanday hisoblayman?

Use the formula: L = 2C + π(D1+D2)/2 + (D2−D1)²/(4C), where L is belt pitch length, C is center distance, D1 and D2 are pulley pitch diameters. This formula works for both V-belts and flat belts.

Ma'lum tasma uzunligidan markazlar oralig'ini qanday topaman?

The center distance can be found by solving the belt length equation: C = [B + √(B² − 8(D2−D1)²)] / 8, where B = 2L − π(D1+D2). This is the inverse calculation.

Tasma uzatmalari uchun minimal o'rash burchagi qancha?

The minimum recommended wrap angle on the smaller pulley is 120° for V-belts and 150° for flat belts. Below these values, belt slip increases significantly and power capacity drops.

Tasma tezligini qanday hisoblayman?

Belt speed v = π × D × n / 60000, where D is pulley diameter in mm and n is speed in RPM. Result is in m/s. Maximum recommended belt speed is typically 25-30 m/s for standard V-belts.

Shkiv diametrlari va tezlik nisbati o'rtasidagi bog'liqlik qanday?

Tezlik nisbati shkiv diametrlarining teskari nisbatiga teng: n2/n1 = D1/D2. Yirikroq haydovchi shkiv tezlik pasayishini anglatadi. Bu tasma sirpanmasligi hisobga olinmagan holda (V-tasmalar uchun odatda 1-2%).

Tasma uzunligidan markazlar orasidagi masofani hisoblash

Wrap Angle

⚠️ Note: Minimum wrap angle on the small pulley should be ≥120° for V-belts. If below this, use an idler pulley or increase center distance.

Misol

Given: D₁=100 mm, D₂=300 mm, C=500 mm

L = 2×500 + π(100+300)/2 + (300-100)²/(4×500)

L = 1000 + 628.3 + 20 = 1648.3 mm
