ABSTRACT:
The invention comprises a device which performs the functions of both a Mooney Viscometer and an Oscillating Disk Rheometer to measure the visco-elastic properties of rubber and rubber-like materials. Rotational and oscillating motion are transmitted to a shaft by means of a sprocket and a hub connected to an eccentric. Rubber samples having a wide range of stiffnesses can be accommodated by a provision for changing the thickness of the sample.
