Gears thiab racks feem ntau yog siv los ua kom tiav qhov kev hloov pauv ntawm kev txhais lus thiab kev sib hloov. Tshwj xeeb:
Conversion Mechanism: Lub khib thiab iav ua ke tsim lub khib thiab pinion mechanism, uas muaj ob lub ntsiab hloov dua siab tshiab. Ua ntej, nws tuaj yeem hloov pauv cov lus tsa suab ntawm lub khib rau hauv kev sib hloov ntawm cov iav; Thib ob, nws tuaj yeem hloov pauv cov lus tsa suab ntawm lub iav mus rau hauv kev txhais lus ntawm lub khib.
Kev ua haujlwm ntawm Gears: Ib lub iav yog cov khoom siv kho tshuab nrog cov hniav txuas ntxiv ntawm nws lub npoo, siv rau kev sib txuas thiab xa hluav taws xob thiab kev txav. Kev ua haujlwm du ntawm cov iav yog qhov tseem ceeb rau kev ua haujlwm tag nrho ntawm lub tshuab ua haujlwm.
Yam ntxwv ntawm Racks: Ib lub khib yog ib hom iav tshwj xeeb, nrog nws cov hniav faib rau ntawm lub khib- zoo li lub cev. Racks tau muab faib ua spur racks thiab helical racks, uas yog ua ke nrog spur gears thiab helical gears feem. Cov hniav profile ntawm ib lub khib yog ncaj, uas yog sib npaug rau lub cylindrical iav nrog lub voj voog infinite pitch vojvoog.
