Bu hasapçy hakda
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.
Köp soralýan soraglar
Gyryş derejesi nädip hasap edilýär?
Çakyrlan çeperiň dişleriniň sanyny çakyrlan çeperiň sanyna böl. 35-dişli çakyrlan çeper 10-dişli çeperde 35/10 = 3.5:1.
Gyryş meňzeşligi tizligi we torkny nädip täsir edýär?
3.5:1 azaltmak gatnaşygy çykyşy girdişden 3.5 gezek yavaşladar emma torkny 3.5 bilen köpeldýär, çakmak ýitirmeleri göz öňünde tutmaýar.
Birikdiren geýim nirä?
Iki gyra çifti bir seriýada bolsa, tutuş gatnaşyk ikisiniň önümidir: 3:1 tapgyr 2:1 tapgyry iýmek 6:1 tutuş azalma berýär.
Redüksion we Overdrive arasy nädip tapawutlanýar?
Bir azaltmak gatnaşygy 1den uly: ol çykany yavaşladar we torkny köpeldir, ýykmak we başlamak ýükler üçin gowy. Bir overdrive 1den az: ol çykany çaltlatýar emma torkny azaldar, ýokary tizlikli öwüşginli gezeşmek üçin gowy.
Gearing free power creates?
Haýba. Geýçler tizligi tork üçin satýarlar, tersine däl - çykan güýç hiç wagt girýänden artyk bolmaz, we akyly geýçler birnäçe göterimi ýykylmak üçin ýitirirler. Eger tork 3.5x artsa, tizlik şol faktor bilen düşer, şonuň üçin tork azda-kände şol bir galýar.
Kalkülatoryň ýol tizligi nädip işleýär?
rpm (input rpm ÷ total ratio ÷ final drive) we tire gyralyk (π × diameter) bilen. Inçlerde tire gyralyk we final drive ratio girin we bu hem mph hem km/h hızyny gaýtarýar.
Haýsy gyra "driving" gyra?
Driving (or input) gear is the one connected to the power source - the motor or pedal side. Driven (output) gear is on the load side. Swapping which is which reverses the ratio, turning a reduction into an overdrive.
