ABSTRACT:
A drive mechanism for a vibratory machine, comprising an input shaft rotatably mountable on the non-vibrating frame of the machine and adapted to be driven, e.g. by a belt drive and pulleys from a standard electric motor, an output shaft mounted in line with the input shaft on the vibratable part of the machine by heavy duty bearings and a flexible resiliently deformable member in the form of an inflatable bellows located between the input and output shafts and preferably sandwiched between plates mounted on the ends of the two shafts and out-of-balance weights on the output shaft whereby, upon rotation of the input shaft, the output shaft will be rotated at the same speed and due to the presence of the weights will cause vibration of the vibratable part of the machine, the flexible resiliently deformable member ensuring that little or no motion other than rotation is transmitted from the output shaft to the input shaft and hence to the electric motor.
