DEVELOPMENT OF THE 1 kN·m STATIC TORQUE STANDARD MACHINE AT UME

C. Dogan, O. Akkoyunlu, C. Kuzu
  • Abstract:
    In the last decade, the increase in the need for the accuracy of the torque metrology created an obligation to produce a new torque standard machine for precise measurement of torque. This paper summarizes the torque standard machine designed and manufactured at UME with the range from 2 N·m up to 1 kN·m. In this machine torque is realized by a lever-mass system. Nominal force arm length of the lever is 0.5 m and constant. In each side of the lever, there are 6 different weight sets; and each set is containing 13 individual mass-stacks. For minimizing the torque loss at fulcrum an aerostatic bearing is used, and the change in the lever position due to the dead weights loading is corrected.
