Kuwonjezera gudumu lapakati kumagwiritsa ntchito mphete yakunja kuti ikwaniritse kusintha kwa kayendedwe.
Kuzungulira kwa giya ndiko kuyendetsa giya lina, ndipo kuyendetsa giya lina, magiya awiriwa ayenera kulumikizidwa. Chifukwa chake chomwe mungawone apa ndikuti giya limodzi likatembenukira mbali imodzi, giya lina limatembenukira mbali ina, zomwe zimasintha njira ya mphamvu. Unyolo ukazungulira, mukakwera njinga, mutha kupeza mosavuta kuti njira yozungulira ya giya ikugwirizana ndi njira ya unyolo, ndipo njira yozungulira ya giya yaying'ono ndi giya yayikulu nayonso ndi yofanana, kotero siyenera kusintha njira ya mphamvu.
Magiya ndi ma transmission amakina omwe amagwiritsa ntchito mano a magiya awiri kuti agwirizane kuti atumize mphamvu ndi kuyenda. Malinga ndi malo omwe ma axes a magiya ali, amagawidwa m'magulu awiri: parallel axis cylindrical gear transmission, intersecting axis bevel gear transmission ndi staggered axis helical gear transmission kuti isinthe njira.
Kutumiza magiya nthawi zambiri kumakhala ndi liwiro lalikulu. Pofuna kulimbitsa kukhazikika kwa kutumiza ndikuchepetsa kugwedezeka, ndibwino kukhala ndi mano ambiri. Chiwerengero cha mano a pinion chikhoza kukhala z1=20~40. Pakutumiza magiya otseguka (otseguka pang'ono), popeza mano a giya makamaka amayamba chifukwa cha kuwonongeka ndi kulephera, kuti giya isakhale yaying'ono kwambiri, giya ya pinion siyenera kugwiritsa ntchito mano ambiri. Nthawi zambiri, z1=17~20 ndi yomwe ikulimbikitsidwa.
Pa tangent point P ya ma gear pitch round awiri, acute angle yomwe imapangidwa ndi common normal ya ma curve awiri a mbiri ya dzino (monga, mphamvu ya mbiri ya dzino) ndi tangent yofanana ya ma pitch round awiri (monga, kayendetsedwe ka kayendetsedwe ka nthawi yomweyo pa point P) imatchedwa Pressure angle, yomwe imatchedwanso mesh angle. Pa gear imodzi, ndi angle ya mbiri ya dzino. Pressure angle ya ma gear okhazikika nthawi zambiri imakhala 20″. Nthawi zina, α=14.5°, 15°, 22.50° ndi 25° imagwiritsidwanso ntchito.
