A belt-drive speed reducer, particularly for driving an airplane propeller from a standard automobile engine, features a protective housing attached to the motor, being supported by suitable borings 22 and 40 of the shaft of a drive pulley 10, on the one hand, turned by the motor crankshaft and, on the other hand, the propeller shaft supporting a driven pulley turned by a belt which, in section, exhibits V-shaped ribs. The bearing of the propeller shaft has on its periphery a disk eccentric with respect to the propeller shaft, the rotation of which disk in the boring of the housing regulates the tension of the belt.
