Abstract

A driving device for the tone shafts of a sound recording device which comprises a motor, a first tone shaft, and a flywheel-mass disposed coaxially to the first tone shaft and operatively connected therewith. A first belt pulley is disposed coaxially to the first tone shaft and likewise operatively connected therewith. A second tone shaft has an axis substantially parallel to the axis of the first tone shaft. A second belt pulley is disposed coaxially to the second tone shaft and operatively connected therewith, as well as having its periphery close to the periphery of the first belt pulley. An elastic belt driving the first belt pulley and the second belt pulley by means of the motor in opposite directions, and the elastic belt has such height, that the portion of the belt disposed between both belt pulleys is not pressed together by the belt pulleys, yet runs freely for such short path, that the longitudinal elasticity being so small, not to exert a disturbing influence on the uniformity of the rotary speed of the second tone shaft during the operatively occurring load fluctuations of the second tone shaft.
