关于此计算器
A gear ratio compares the teeth on the driven (output) gear to the driving (input) gear: ratio = driven / driving. It is the fundamental trade-off of gearing — a ratio above 1 is a reduction that turns the output slower but multiplies torque, while a ratio below 1 is an overdrive that spins faster but with less torque. Concretely, output RPM = input RPM ÷ ratio and output torque = input torque × ratio, so speed and torque always move in opposite directions (ignoring friction losses), keeping the power roughly constant.
As a worked example, a 10-tooth driving gear meshing with a 35-tooth driven gear gives a ratio of 35 / 10 = 3.5:1. Feed it 1,000 rpm and 20 N·m and the output turns at 1,000 / 3.5 ≈ 286 rpm but delivers 20 × 3.5 = 70 N·m. For a compound gear train, add a second pair under advanced options and the overall ratio is the product of the two stages — a 3:1 stage feeding a 2:1 stage gives 6:1 total. Enter a tyre diameter and final drive ratio and the tool also works out road speed from the wheel rpm.
Gear ratios are how machines match a power source to a load: low gears give a car or bicycle the torque to climb and accelerate, high gears give efficient cruising, and reduction gearboxes let small fast motors drive heavy slow loads. The same principle sizes winches, conveyors, clock mechanisms and drill speeds.
经常问到的问题
如何计算渔具比率?
驾驶用具上的牙齿数除以驾驶用具上的牙齿数。10牙驾驶用35牙驾驶的齿轮数为35/10=3.5:1。
渔具比率如何影响速度和力力?
下降率为3.5:1, 将产出减为3.5倍, 减幅比输入慢3.5倍, 将压强乘以3.5, 忽略了摩擦损失。
复合齿轮比率是什么?
当两个配对是系列配对时,总比率是两个配对的产物:3:1级喂养2:1级喂养6:1级总减产。
减税和过度开战有什么区别?
降低率大于 1: 它会减慢输出和倍倍倍的扭压, 有利于攀登和开始负荷。 过度驱动低于 1: 它会加速输出, 减少 扭压, 有利于高效高速高速巡航 。
调整能创造自由力量吗?
否。 硬力的齿轮贸易速度,而不是相反——输出力永远无法超过输入,真正的齿轮会因摩擦而损失几个百分点。 如果硬力上升3.5x,速度会下降同样的系数,因此能量会保持不变。
计算器如何计算出公路速度?
从轮式车轮转盘(总正数Rpm 最终驱动器总比率)和轮胎环绕(xx直径)开始,输入轮胎直径英寸和最后驱动率,并返回每小时和每小时的速度。
哪个是"驾驶"装备?
驾驶(或输入)装置是连接到动力源——发动机或踏板一侧的装置。驱动(输出)装置在负载一侧。 交换是将比率反转,将减速变成超速驾驶。
