TusiavNcej yog dav siv nyob rau hauv ntau yam kev lag luam gearbox vim nws lub peev xwm los muab siab siab torque, du suab, thiab kev xauv lub peev xwm ntsuas phoo. Ib qho ntawm nws cov ntawv thov tseem ceeb yog nyob rau hauv cov tshuab ceev ceev, qhov uas nws pab ua kom tiav kev tswj hwm loj dua thaum tswj cov hwj huam kev ua tau zoo. Qhov no ua rau nws zoo tagnrho rau cov machinery xav tau cov hau kev xav tau, xws li cov siv tawv, xws li cov khoom siv conveyor, elevators, thiab nqa cov khoom siv.

Nyob rau hauv kev lag luam automotive, cab cov iav qhwv tau siv hauv cov kev sib ntsib zuj zus, ua kom pom kev du thiab tswj kev txav ntawm tsheb. Lawv kuj muaj nyob hauv winches thiab hoists, muab kev ruaj khov thiab tiv thaiv rov qab tsav tsheb, uas ua kom muaj kev nyab xeeb rov qab.

Hauv kev lag luam machinery, cab iav qhwv ua si lub luag haujlwm tseem ceeb hauv kev sib koom tes, nias, uas tswj tau cov khoom siv kev sib txuas thiab cov khoom siv hluav taws xob yog qhov tseem ceeb. Lawv kuj siv nyob rau hauv Textile Machine, khoom siv kho mob, thiab cov khoom siv ua haujlwm, ua rau muaj kev pom zoo thiab thauj khoom.

Tsis tas li ntawd, cov tshuab hluav taws xob muaj nyob hauv cov khoom siv hluav taws xob hauv tsev, thiab cov khoom siv suab paj nruag kho qhov chaw. Lawv cov haujlwm ruaj khov, kev ua haujlwm nyob ntsiag to, thiab ua haujlwm ua rau lawv qhov tsis tseem ceeb hauv kev thov niaj hnub no
