Chiyerekezo cha zida za bevel chitha kuwerengedwa pogwiritsa ntchito fomula:
Gear Ratio = (Nambala ya Mano pa Zida Zoyendetsedwa) / (Nambala ya Mano pa Zida Zoyendetsa)
Mu a zida za beveldongosolo, zida zoyendetsa ndi zomwe zimatumiza mphamvu ku zida zoyendetsedwa.Kuchuluka kwa mano pa giya lililonse kumatsimikizira kukula kwake ndi liwiro lozungulira.Mwa kugawa chiwerengero cha mano pa giya loyendetsedwa ndi chiwerengero cha mano pa galimoto galimoto, mukhoza kudziwa chiŵerengero cha zida.
Mwachitsanzo, ngati giya yoyendetsa ili ndi mano 20 ndipo giya yoyendetsedwa ili ndi mano 40, chiŵerengero cha zida chingakhale:
Kuchuluka kwa zida = 40/20 = 2
Izi zikutanthauza kuti pakusintha kulikonse kwa zida zoyendetsera, zida zoyendetsedwa zimazungulira kawiri.Chiŵerengero cha giya chimatsimikizira kuthamanga ndi mgwirizano wa torque pakati pa magiya oyendetsa ndi oyendetsedwa mu abevel gear system.
