Ku saabsan Kalkaaliyahan
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.
Su'aalaha badanaa la isweydiiyo
Sidee waa Gear ratio la xisaabiyey?
Qaybta tirada ilkaha on gear driven by tirada on gear driving. A 35-ilkaha driven gear on a 10-ilkaha darawalka waa 35 / 10 = 3.5:1.
Sidee Gear ratio saamayn ku yeelataa xawaaraha iyo torque?
A hoos u dhigista 3.5: 1 qiyaasta ka dhigi kartaa soo saarka 3.5 jeer ka dhakhso badan in ay soo gasho laakiin multiplies torque by 3.5, ka fogaanshaha khasaaraha dabacsanaanta.
Maxaa ah qiyaasta gear isku dhafan?
Marka laba nooc oo gear ah waa in series, qiyaasta guud waa natiijada labada: 3:1 heerka cunto 2:1 heerka siiyaa 6:1 hoos u dhac guud.
Waa maxay farqiga u dhexeeya hoos u dhigista iyo overdrive?
A hoos u dhigista qiyaasta waa ka weyn yahay 1: waxay hoos u soo saarka iyo multiplies torque, wanaagsan oo u socda iyo qaadashada bilaabi. A overdrive waa ka yar 1: waxay kordhisaa soo saarka kor laakiin hoos u dhigi torque, wanaagsan oo ku habboon xawaaraha sare ee xawaaraha sare.
Ma gearing abuurtaa awood bilaash ah?
No. Gears dhaqdhaqaaqa ganacsiga ee torque, ma aha habka kale ee ku wareegsan - awoodda soo saarka ma ka badnayn in la soo galo, iyo gears dhabta ah ay ku lumiso boqolkiiba qaar ka mid ah si ay u qalalan. Haddii torque u sii kor u 3.5 ×, speed hoos u dhaca by isku faahfaahinta sidaas awoodda ku nool oo ku saabsan sida la midka ah.
Sidee bay xisaabinta u shaqeeyaan xawaaraha jidka?
Ka rpm wheel (input rpm ÷ guud ah ÷ ugu dambeysay drive ratio ÷) iyo wareega tiirka (π × diameter). Ku dar tiirka diameter in inji iyo tiirka ugu dambeysay ratio iyo wuxuu ku soo laabtay xawaaraha labada mph iyo km / h.
Waa maxay qalabka "xawaaraha"?
The driving (ama soo gelinta) gear waa mid ka mid ah oo la xiriira awoodda - motor ama dhinaca pedal. The driven (soo saaraha) gear waa dhinaca culayska. Isbedelka kaas oo ah mid ka soo horjeeda qiyaasta, ka dhigaysa hoos u dhaca in overdrive.
API — isticmaal xisaabinta ka code
Wici xisaabinta sida free JSON endpoint - key ma loo baahan yahay. Dib u soo dir qiimaha goobta hoos ku qoran sida parameters su'aal ama JSON. Wax kasta oo aad ka maqan tahay isticmaalaa default la mid ah ee boggani waa hore loo buuxiyey la; parameter aan la aqoon waa 400, marnaba ma aha zero maqan. Akhri dhammaan API xuquuqda →
