Tus cab iav reducer yog lub zog xa hluav taws xob uas siv lub zog hloov pauv ntawm lub iav kom decelerate tus naj npawb ntawm cov kiv puag ncig ntawm lub cev muaj zog (lub cev muaj zog) mus rau qhov yuav tsum tau muaj kev hloov pauv thiab tau txais lub zog loj loj. Nyob rau hauv cov txheej txheem siv los xa lub zog thiab cov lus tsa suab, daim ntawv thov ntau yam ntawm reducer yog qhov dav heev. Nws cov kab tuaj yeem pom nyob rau hauv kev sib kis ntawm txhua yam ntawm cov tshuab, los ntawm cov nkoj, tsheb, locomotives, cov tshuab hnyav rau kev tsim kho, kev ua tshuab thiab cov khoom siv tsis siv neeg siv hauv kev lag luam machinery, rau cov khoom siv hauv tsev niaj hnub. , moos, thiab lwm yam. Daim ntawv thov ntawm lub reducer tuaj yeem pom los ntawm kev sib kis ntawm lub zog loj mus rau kev sib kis ntawm cov khoom me me thiab lub kaum ntse ntse. Hauv cov ntawv thov kev lag luam, lub reducer muaj lub luag haujlwm ntawm deceleration thiab torque nce. Yog li ntawd, nws yog dav siv nyob rau hauv ceev thiab torque conversion khoom.

Txhawm rau txhim kho qhov ua tau zoo ntawm cov cab iav reducer, cov hlau tsis yog hlau feem ntau yog siv los ua cov cab iav thiab cov hlau tawv ua cov cab cab. Vim hais tias nws yog ib qho zawv zawg kev sib txhuam tsav, thaum lub sijhawm ua haujlwm, nws yuav ua kom muaj cua sov siab, uas ua rau cov khoom ntawm cov reducer thiab cov foob. Nws muaj qhov sib txawv ntawm thermal expansion ntawm lawv, uas ua rau muaj qhov sib txawv ntawm txhua qhov mating nto, thiab cov roj yuav thinner vim qhov kub thiab txias, uas yog ib qho yooj yim ua rau to. Muaj plaub lub laj thawj tseem ceeb, ib qho yog seb qhov sib txuam ntawm cov ntaub ntawv yog qhov tsim nyog, lwm qhov yog qhov zoo ntawm qhov meshing kev sib txhuam nto, qhov thib peb yog xaiv cov roj lubricating, seb qhov sib ntxiv yog qhov tseeb, thiab plaub yog qhov zoo ntawm kev sib dhos thiab kev siv ib puag ncig.
