Output (English): The gear transmission according to the invention consists of a drive disk (11), belt (14) a disengagement disk (12) and a tension roller (13) varying the transmission ratio of the system, whereby one of the disks  (11, 12) is made as a disk (11) with a peripheral running surface with a fixed radius for engagement with the drive belt (14) having a V-shaped profile with angled flanks (141) and a relatively flat inner peripheral surface (143) for engagement with said peripheral running surface (143) of said drive disk (111), while the other disk (12, 11) is made as a disk (121) with two skew surfaces for engagement with the belt angled flanks . The skew engagement surfaces are spring-loaded with respect to each other in axial direction and are disposed on two resiliently coupled parts of the second drive disk (121) that are prestressed in axial direction toward each other along axis of the second drive disk (121), whereby the belt (14) is engaged with the second drive disk (121) only by i
