Abstract

The invention relates to a vertical on-site torque calibration device based on a speed reducer force application principle and belongs to the torque calibration field. The device comprises a first electric lead screw lifting platform, a second electric lead screw lifting platform, a pressing sheet, a standard lever, a sensor to be measured, a lateral force resistance device, a pedestal, a movable working table, a first standard-type S sensor, a second standard S type sensor, a motor, a circular gear and a sector gear. Aiming at a large torque calibration demand, based on a current test condition, a set of on-site torque calibration device is established. A lever balance principle is used, and through the lever, a generated standard moment value is loaded and is compared to a measured data of a calibrated sensor so as to reach a calibration purpose. The device can be simply and rapidly operated. In the prior art, measurement precision is low, time is long and the device is not suitable for on-site detection. By using the device of the invention, the above problems are solved, requirements of measured value transmission and traceability are satisfied and large torque on-site calibration can be realized.

Description

technical field [0001] The invention relates to a vertical on-site torque calibration device based on the force application principle of a reducer, belonging to the field of torque calibration. Background technique [0002] The aero-engine test bench is a test platform for the comprehensive performance parameters of the aero-engine, in which the dynamometer, as a torque measuring instrument, is the main measurement equipment for the output power of the aero-engine and the key measurement equipment for the test bench. Output power is a main indicator of aero-engines. Domestically, there are two methods for testing torque parameters: laboratory calibration and on-site calibration. At present, there is no suitable calibration method, and the on-site online calibration technology of dynamometers is still in the field of measurement. Blank. [0003] In the prior art, the torque calibration machine is a device with the nature of balance work. It uses a threaded lifting mechanism ...
