Gear hobbing tshuab yog cov cuab yeej siv tshuab siv dav tshaj plaws hauv cov cuab yeej siv tshuab ua haujlwm, uas tuaj yeem txiav cov spur thiab helical cylindrical zog, nrog rau cov cab iav thiab sprockets. Lub tshuab ua cov iav uas siv cov hobbs los ua cov spur, helical, thiab herringbone cylindrical gears thiab cab iav los ntawm txoj kev loj hlob. Lub tshuab no tuaj yeem siv ntau yam ntawm cov khoom siv nrog cov hniav tshwj xeeb, xws li splines thiab sprockets, siv cov hobs tshwj xeeb. Qhov tseeb machining ntawm cov iav hobbing tshuab yog 7 ~ 6 qib (JB179-83), thiab cov iav hobbing tshuab yog 4 ~ 3 qib. Qhov siab tshaj plaws ua txoj kab uas hla yog mus txog 15 meters.
