M'kupita kwa nthawi, magiya akhala mbali yofunika ya makina. M'moyo watsiku ndi tsiku, kugwiritsa ntchito magiya kumawonedwa kulikonse, kuyambira panjinga zamoto mpaka ndege ndi zombo.
Mofananamo, magiya amagwiritsidwa ntchito kawirikawiri m'magalimoto ndipo adutsa zaka zana zapitazo, makamaka ma gearbox a magalimoto, omwe amafuna kuti magiya asinthe magiya. Komabe, eni osamala kwambiri apeza chifukwa chake magiya a gearbox amawongoleredwa, koma ambiri aiwo ndi a helical?
M'malo mwake, magiya a gearbox ndi mitundu iwiri:zida za helicalndikulimbikitsa magiya.
Pakadali pano, ma gearbox ambiri pamsika amagwiritsa ntchito zida za helical. Kupanga magiya a spur ndikosavuta, kumatha kukwaniritsa ma meshing mwachindunji popanda cholumikizira, ndipo kuyika komaliza kwa shaft kumatha kugwiritsa ntchito mayendedwe akuya a groove, makamaka popanda mphamvu ya axial. Komabe, padzakhala zolakwika pakupanga ma spur gears, zomwe zidzapangitse liwiro losagwirizana, lomwe silili loyenera kwa injini zothamanga kwambiri komanso zothamanga kwambiri.
Poyerekeza ndi zida za spur, zida za helical zimakhala ndi mano otsetsereka, omwe ali ngati kupotoza screw, kupotoza pang'ono, pali mphamvu yoyamwa. Mphamvu yofanana ya mano owongoka imakhala ngati meshing. Choncho, pamene giya ali mu giya, mano helical kumva bwino kuposa mano owongoka. Komanso, mphamvu yonyamula mano a helical imayenda kuchokera kumapeto mpaka kumapeto, kotero sipadzakhala kugunda kwa mano pamene magiya akusuntha, ndipo moyo wautumiki ndi wautali.
Zida za helical zimapita patsogolo, ndipo mano amakhala ndi kuphatikizika kwakukulu, kotero kumakhala kokhazikika komanso kumakhala ndi phokoso lochepa panthawi yopatsirana, ndipo ndi yoyenera kugwiritsidwa ntchito poyendetsa galimoto komanso katundu wolemetsa.
