A chain gearing includes a drive sprocket installed on the drive shaft, driven sprocket installed on the driven shaft, and a chain surrounding both sprockets. Additionally it includes the drive, driven, parasitic pinions and axle, at that the drive pinion is installed on the drive shaft, the driven pinion is installed on the driven shaft, parasitic pinion is installed in free way on the axle, and the ratio of the numbers of teeth of the sprockets, pinions and the module of the pinion are chosen from the condition:where Z, Z– the number of teeth of the drive and the driven sprockets, respectively;Z, Z, Z– the number of teeth of the drive and the driven and parasitic pinions, respectively;m – module of the pinions;a – inter-axial distance of chain drive. |
