Beschreibung
Zusammenfassung:	The invention relates to a continuously variable diameter transmission wheel comprising a plurality of radially movable support elements for a belt or chain, the threaded hole of which is connected to the thread of a corresponding radial screw rod, wherein a conical small gear is mounted on the end of each radial screw rod towards the center of the transmission wheel, the conical small gear located between the first and second parallel bevel gears mounted on the transmission wheel shaft and meshing with it, an actuator for smooth adjustment of the transmission wheel diameter, a frame with radial slots for moving the support elements and for fixing the radial screw rods, and a housing connected to the frame in which the bevel small gears and the first and second bevel gears are placed. What is new is that the actuator is mounted inside the transmission wheel housing between the first and second bevel gears, and the shaft of the transmission wheel is a hollow shaft, with at least one opening on the side for connecting the means of controlling the operation of the actuator through the hollow shaft. Leiutis käsitleb sujuvalt muudetava läbimõõduga ülekanderatast, mis sisaldab rihma või keti jaoks mitut radiaalsuunas liigutatavat tugielementi, mille keermestatud ava on ühendatud vastava radiaalse kruvivarda keermega, kusjuures iga radiaalse kruvivarda ülekanderatta tsentri poolsesse otsa on kinnitatud kooniline väikehammasratas, mis asub ülekanderatta võllile kinnitatud esimese ja teise paralleelse koonushammasratta vahel ja on nendega hambumises, täiturseadet ülekanderatta läbimõõdu sujuvaks reguleerimiseks, radiaalsete piludega raami liigutatavate tugielementide jaoks ja radiaalsete kruvivarraste fikseerimiseks ja raamiga ühendatud korpust, mille sisse on paigutatud koonilised väikehammasrattad ja esimene ja teine koonushammasratas. Uudne on see, et täiturseade on paigaldatud ülekanderatta korpuse sisse esimese ja teise koonushammasratta vahele ning ülekanderatta võlliks on õõnesvõll, mille küljel on vähemalt üks ava täiturseadme töö juhtimise vahendite ühendamiseks läbi õõnesvõlli.
