Lub helical khib yog ib hom khib nrog cov hniav helical. Piv nrog rau cov khib nyiab tsis tu ncua, nws tuaj yeem tiv taus ntau dua thiab ua haujlwm nrog lub suab qis, ua rau nws siv dav hauv kev lag luam.
Thaum lub helical khib meshes, lub kaum sab xis helix generates axial thrust, yuav tsum tau ceev faj tsim kom sib npaug no axial quab yuam. Tsis tas li ntawd, thaum ob lub helical cov hniav nrog lub kaum sab xis helix mesh los ua ib qho kev sib tw helical iav, nws cov shafts tuaj yeem hla kom haum rau qhov sib txawv qaij kaum, tab sis qhov taw tes tiv tauj txwv nws cov load -cov kabmob muaj peev xwm.
Thaum ob helical hniav nrog opposite helix kaum mesh, lawv tsim ib tug hla helical khib. Nws cov shafts tuaj yeem hla ntawm ntau lub kaum ntse ntse kom hloov mus rau ntau yam kev sib dhos. Txawm li cas los xij, vim yog qhov taw tes ntawm cov hniav ntawm cov hniav, lub load-cov kabmob muaj peev xwm ntawm cov hlais helical iav yog qis dua li ntawm cov iav helical ib txwm, ua rau nws haum rau lub teeb -load daim ntaub ntawv.
