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.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani chida chosinthira?
Kugawa ziweto ziweto pa driven gear ndi ziweto pa driving gear.A 35-zomera driven gear pa 10-zomera woyendetsa ndi 35 / 10 = 3.5: 1.
Kodi gear ratio imakhudza bwanji kuthamanga ndi kuzungulira?
Kuchepetsa 3.5:1 chimasintha 3.5 nthawi zosatha kuposa kulowa koma ama multiplies torque ndi 3.5, kunyalanyaza kuwonongeka kwa kukana.
Kodi ndi chiyani chida chophatikizika?
Pamene awiri gear mabanja ndi m'gulu, khalidwe lonse ndi chinthu cha awiri: 3:1 gawo kudyetsa 2:1 gawo amapatsa 6:1 kuchepetsa zonse.
Kodi pali kusiyana kotani pakati pa kuchepetsa ndi overdrive?
Kuchepetsa kusiyana ndi lalikulu kuposa 1: amalepheretsa kutulutsa ndi kuwonjezeka torque, bwino kwa kunyamula ndi kuyamba. Overdrive ndi ochepa kuposa 1: amafulumizitsa kutulutsa mpaka koma amachepetsa torque, bwino kwa efficient high-speed cruise.
Kodi gearing amaumba ufulu mphamvu?
No. Gears malonda liwiro kwa torque, si choncho - mphamvu ya kutulutsa sakhoza kupitilira kulowa, ndi real gears kuwononga peresenti zingapo kuti kukana. Ngati torque akubwera ndi 3.5 ×, liwiro amawasiya ndi chinthu chimodzimodzi kotero mphamvu amakhazikika za chimodzimodzi.
Kodi calculator ntchito m'njira yamphamvu?
Kuchokera pa rpm ya wheel (input rpm ÷ kulemera kwa ÷ kuyendetsa komaliza) ndi kuzungulira kwa tires (π × kuzungulira). Ikani kuzungulira kwa tires m'inchi ndi kuzungulira komaliza ndipo imabwerera kufulumira m'mitundu yonse ya mph ndi km / h.
Kodi ndi chiyani chomwe chimayambitsa "kuyendetsa" kwa makina?
Kuyendetsa (kapena kulowa) gear ndi imodzi yogwirizana ndi mphamvu yochokera - motor kapena pedal mbali. The driven (output) gear ndi pa zonyamula mbali. Swapping amene ndi amene amasinthanitsa khalidwe, kuzungulira kuchepetsa mu overdrive.
