Abstract
System for determining rheological properties of grease, includes a grease worker having a cylinder intended to contain the grease and a piston intended to move inside the cylinder in a first direction and in a second opposite direction and provided with holes. The grease worker further including a seal provided between the piston and the cylinder, force for measuring the force required to push the grease through the holes of the piston is measured an electrical motor and an eccentrical connection transforming the rotating motion of the motor in a translation motion pushes the grease thought the holes, a thermocouple for measuring a temperature of the cylinder, a fan and a heater for regulating temperature for maintaining constant the measured temperature at a predetermined temperature, and a computing unit configured to determine at least one rheological property of the grease from the measured forces and from the seal friction.
