US Patent 10281450 Universal machine for rheological and mechanical tests

An universal machine is comprised of the arrangement of a set of modules (CM) that make up means of rheological and mechanical tests for the assessment of longitudinal forces perpendicular to the rotation direction of an alternate current servomotor. Its modules are comprised of: a) structural organization; b) electronic components cabinet of the electronics system (St)/(Sw); c) dry gear reducer; d) alternate current servomotor; e) fast coupling system for changing geometries; f) test containers, as well as devices for the execution of materials in hardened state; g) load cell device for recording regular longitudinal forces. The machine provides the interconnection with a data processing system (PC) and the aforementioned modules (CM) are controlled by a specific electronic system (St) for speed control, torque control and rotation direction.
