Iiseti zegiya ze-Helical ziyinxalenye ebalulekileyo kwiibhokisi zegiya zamashishini, ezibonelela ngokutyibilika nokuhanjiswa kwamandla okufanelekileyo. Ngokungafaniyo neegiya ze-spur, iigiya ze-helical zinamazinyo aneengile azibandakanya ngokuthe ngcembe, ebonelela ngokusebenza okuzolileyo kunye nokunciphisa ukungcangcazela. Oku kubenza balungele isantya esiphezulu, usetyenziso olunomthwalo ophezulu oluqhele ukufunyanwa kumashishini afana nokuvelisa, ukuvelisa umbane, kunye nokuphatha izinto eziphathekayo.

Amazinyo e-angle e-helical gears abangela indawo yokudibanisa ixesha elide phakathi kweegesi, ukusabalalisa umthwalo ngokulinganayo. Eli nqaku longeza ukuqina kwaye livumela iiseti zegiya ze-helical ukuphatha i-torque ephezulu kunye nemithwalo yamandla, izenza zilungele kakuhle iibhokisi zegiya zamashishini apho ukuchaneka kunye nokuthembeka kubaluleke kakhulu. Ukongeza, ukuyilwa kweegiya ze-helical kunciphisa ukunxiba, okunegalelo kubomi obude benkonzo kunye nokunciphisa iindleko zokulondolozwa.

Iibhokisi zegiya zemizi-mveliso ezineegiya ze-helical zisetyenziswa kuluhlu olubanzi loomatshini, kubandakanya neenkqubo zokuhambisa, izityuli, izixube, kunye noomatshini abakhulu apho ukuhanjiswa kwamandla agudileyo kubalulekile ekusebenzeni ngokufanelekileyo. Ukukwazi kweeseti ze-helical gear ukuze zisebenze ngokufanelekileyo, naphantsi kwemithwalo enzima, kubenza ukuba bakhethe ukhetho olufunekayo kwizicelo zemizi-mveliso.
