DEVELOPMENT OF THE 1 kN×m TORQUE STANDARD MACHINE
K. Ohgushi, T. Tojo, A. Furuta
Abstract:
Research is being conducted at the National Research Laboratory of Metrology (NRLM), Japan, for the purpose of creating a technical base for a national torque standard and constructing a widely accepted torque traceability system. As part of the research, a torque standard machine of rated capacity 1 kN × m was developed. This machine has a variety of features enabling it to perform precise measurements of torque, including the correction of the lever length due to deadweights loading and an aerostatic bearing in order to minimize torque loss caused by friction at the fulcrum. In this paper, the torque standard machine is outlined.
