Problems solved by technology

[0003] When adding a weight or a calibration cylinder to the calibration arm for calibration, since the force is unilaterally applied, a radial force is also applied to the torque meter spindle at the same time. When the weight or calibration cylinder is applied After a large radial force is applied, it will inevitably cause a certain deformation of the torque meter spindle drive system and generate additional frictional resistance, which affects the calibration accuracy

Abstract

The invention discloses a hydraulic balance loading large torque static calibration device which comprises a torquemeter main shaft. Both ends of the torquemeter main shaft are symmetrically and fixedly connected with correction arms. Upper and lower ends of each correction arm are respectively connected with an upper triangular knife and a lower triangular knife. Each upper triangular knife is connected with an upper V-shaped block. Each lower triangular knife is connected with a lower V-shaped block. The lower part of a lower V-shaped block is provided with a first pull and press sensor and a first cylinder. The lower part of a lower V-shaped block on the other end is provided with a second pull and press sensor and a second cylinder. According to the invention, the left first cylinder is used to carry out balance loading; pulling and pressing are carried out at the same time; the torquemeter main shaft only bears torque, but does not bear a radial force; deformation is reduced; frictional resistance is reduced; and the static calibration precision is improved.

Description

technical field [0001] The invention relates to a measuring device, in particular to a static calibration device for a large torque meter on a test stand. Background technique [0002] On various test benches involving torque measurement, the torque measurement is generally done by a torque meter, and the torque meter generally needs to be calibrated statically by adding a weight or a calibration cylinder to the calibration arm. [0003] When adding a weight or a calibration cylinder to the calibration arm for calibration, since the force is unilaterally applied, a radial force is also applied to the torque meter spindle at the same time. When the weight or calibration cylinder is applied After a large radial force is applied, it will inevitably cause a certain deformation of the torque meter spindle drive system and generate additional frictional resistance, which affects the calibration accuracy.
