I-Calculator ye-Gear Ratio
Izinga le-gear, isivinini sokuphuma kanye ne-torque - eyodwa noma ehlanganisa, ngejubane lendlela.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Indlela ecalwa ngayo i-gear ratio?
Yahlula inani lezinhlamvu ku-gear eqhutshwa yinani le-gear eqhuba. I-gear eqhutshwa ngezinhlamvu ezingu-35 ku-driver enezinhlamvu ezingu-10 ilingana ne-35 / 10 = 3.5:1.
Uyini umkhawulo wegiya othinta isivinini ne-torque?
Ukunciphisa isilinganiso se-3.5:1 kushintsha isingeniso sibe 3.5 izikhathi ezihamba kancane kunesingeniso kodwa kuphinda i-torque ngo-3.5, kungakhathaliseki ukulahleka kokuqhuma.
Yini i-gear ratio ehlobene?
Uma amagiya amabini alinganayo eqhubeka, isilinganiso esiphelele siyimikhiqizo yesibili: isigaba 3:1 esidla isigaba 2:1 sinikeza 6:1 ukuncipha okuphelele.
Yini ushintsho phakathi kokuncipha nokuhamba kancane okuphezulu?
Ukwehla komugqa kukhulu kuna-1: kukhawulela ukukhishwa futhi ku multiplies i-torque, okuhle ukuphakama nokuqapha ukuthunyelwa. Ukwehla komugqa kuncane kuna-1: kukhawulela ukukhishwa kodwa kunciphisa i-torque, okuhle ukudluliswa okuphezulu kwe-speed.
Ingabe ukugembula kwenza amandla amahhala?
Akuna. Amageyimu athengisa isivinini se-torque, hhayi indlela ehlukile - amandla okuphuma angafinyeleli ku-input, futhi amageyimu angempela alahlekelwa yingxenye embalwa yephesenti yokugqwala. Uma i-torque idlula ku-3.5 ×, isivinini sikhuphuka ngengxenye efanayo ngakho amandla ahlala ngokufanayo.
Indlela i-calculator esebenza ngayo ukukhawulela isivinini sendlela?
Kusuka ku-rpm yesondo (i-rpm yokungena ÷ ukulingana okuphelele ÷ uqhubo oluphelile) kanye ne-tire circumference (π × ubukhulu be-tire). Faka ubukhulu be-tire nge-intshi kanye no-ubukhulu bokuhamba okuphelile futhi ibuyisela isivinini ku-mph kanye ne-km/h.
I-gear enjani i-gear "ehamba"?
I-gear ehambayo (noma engeniswe) iyiyona exhunywe emthonjeni wokusebenza — imoto noma i-pedal ngakwesobunxele. I-gear ehambayo (ephumayo) itholakala ngakwesobunxele. Ukushintshana okuzoshintsha isilinganiso, kuguqula ukuncipha kube yi-overdrive.
