Mechanism special for acting counter balance force of ultra-large torque standard device on ground

Abstract

The invention relates to a mechanism special for acting counter balance force of an ultra-large torque standard device on the ground. The mechanism comprises a standard force arm, supporting components, a balance force arm and a base, a tested torque sensor, two sets of standard weights and two sets of leveling mechanisms are arranged between the standard force arm and the balance force arm, and the standard weights and the leveling mechanisms are used for carrying out clockwise and anticlockwise testing on the tested torque sensor. In the testing process, one standard weight and one leveling mechanism are distributed on every two opposite angles of the standard force arm and the balance force arm, gear motors are arranged in the leveling mechanisms, and drive the leveling mechanisms, and the balance force arm is made to rotate around the corresponding supporting component and used for balancing the standard force arm. According to the mechanism, large enough balance torque can be provided for standard torque, and meanwhile it can be ensured that deformation, caused by twisting force, of a machine tool body is avoided.

Description

technical field [0001] The invention relates to a measurement detection, torque detection calibration, and torque testing device, in particular to a mechanism specially used for a super large torque standard device to balance the reaction force acting on the ground. Background technique [0002] Deadweight torque standard device is a high-precision torque measurement equipment. This equipment is composed of a standard force arm, a standard weight, a force arm supporting part, a machine tool body and a balance part. Traditional balancing components are fixed on the machine tool and driven by a motor. However, this structure cannot be realized for the ultra-large deadweight torque standard machine. Because the existing motor cannot provide a large enough output torque to balance the super large standard torque produced by the standard force arm weight. In order to solve this problem, it is necessary to adopt a design technology that balances the reaction force acting on the...
