Tishli uzatma nisbati nima?

Gear ratio (i) is the ratio of angular velocities between input and output shafts. It equals the ratio of teeth counts i = Z2/Z1 or speed ratio i = n1/n2. A ratio greater than 1 means speed reduction (torque multiplication).

Ko'p bosqichli tishli uzatma nisbatini qanday hisoblash mumkin?

For a multi-stage gear train, the total ratio is the product of individual stage ratios: i_total = i1 × i2 × i3 × ... For example, two stages with i=3 and i=4 give i_total = 12.

Tishli uzatma nisbati va tezlik nisbati o'rtasidagi farq nima?

They express the same relationship differently. Gear ratio i = Z_driven/Z_driver = n_input/n_output. Speed ratio is the inverse: output_speed/input_speed = 1/i. Both describe the same gear mesh.

Bir bosqichli uzatma uchun odatiy nisbat diapazoni qanday?

Bir bosqichli to'g'ri tishli uzatmalar odatda 1:1 dan 6:1 gacha nisbatga erishadi. Qiyshiq tishli uzatmalar 10:1 gacha yetishi mumkin. Yuqoriroq nisbatlar uchun ko'p bosqichli uzatmalardan (masalan, ikki bosqichli reduktor: 36:1 gacha) yoki qurt tishli uzatmalardan (5:1 dan 100:1 gacha) foydalaning.

Tishli uzatma nisbati momentga qanday ta'sir qiladi?

Torque is multiplied by the gear ratio (minus losses): T_output = T_input × i × η. A 3:1 reduction triples the torque while reducing speed by 3. This is the fundamental trade-off in gear systems.

Bu yerda η — har bir bosqich uchun FIK (to'g'ri tishli uzatmalar uchun odatda 97–99%).

Misol — ikki bosqichli reduktor

Given: Stage 1: Z₁=18, Z₂=72; Stage 2: Z₁=20, Z₂=60; Input = 1500 RPM, 15 kW

i₁ = 72/18 = 4.0, i₂ = 60/20 = 3.0

i_total = 4.0 × 3.0 = 12.0

n_out = 1500 / 12 = 125 RPM

T_out = 9549 × 15 / 125 × 0.97² = 1080 N·m
