Chotenthetsera chalafini chonyamula.

Chitofu choyatsira palafini chonyamula ndi chipangizo chapakhomo, chomwe chimaphatikizapo msonkhano wa chitofu, chopangira gasi, msonkhano wa mphika wamafuta, chassis ndi chipangizo chosinthira zingwe.Chipangizo chosinthira chingwe chimaphatikizapo shaft yozungulira ndi gear yomwe imamangiriridwa pamtengo wozungulira.Manja a shaft ozungulira, kombo, choyikapo, choyikapo nyali, chingwe cha chingwe ndi chingwe.Nkhono yachitsulo imakhala ndi malaya amtundu wa coaxial cylindrical okhala ndi ma diameter osiyanasiyana, malaya apakati a chingwe, mkati mwa chingwe chachitsulo ndi cylindrical rivet.Pali mikwingwirima iwiri yogawidwa mofanana pakhoma lozungulira la mkono wa waya.Pamayendedwe omwe ali pamwambawa, khoma lozungulira la manja a nyali limagawidwanso mofanana ndi njira zowongolera (kapena zoyima) zofanana ndi kuchuluka kwa njira zoyendetsera oblique.Chitsanzo chothandizira chimakhala ndi ntchito yabwino yosindikizira ndipo kayendetsedwe ka nyali ya nyali ndi koyenera.Ndi chitofu choyenera cha parafini chotenthetsera nyumba ndi mahotela.
