Abstract

The invention discloses shaft-class rotation rigidity detection equipment, comprising a first clamping device, an angle encoder, a torque sensor, a second clamping device, a speed reducer, a servo motor, a controller and a data collection card. Measurement and control software of the controller controls the servo motor (forward / backward) to drive the angle sensor and the torque sensor to generate real-time angle and torque changes. The data collection card synchronously collects electrical signal data related to the angle encoder and the torque sensor, automatically records and processes data through the measurement and control software, automatically calculates shaft-type rigidity and a lag angle, and draws an angle-torque curve according to the collected electrical signal data. The equipment carries out detection operation of shaft-type rigidity by automatically collecting related data and processing the data instead of a mode of manually hanging weights, and thus man-made clerical errors are prevented, detection result measurement errors are reduced, and the detection accuracy is raised.

Description

technical field [0001] The invention relates to the technical field of shaft detection equipment, and more particularly, the invention relates to a shaft rotation stiffness detection device. Background technique [0002] At present, the shaft stiffness detection mainly adopts the method of pure mechanical hanging weights, and the data processing adopts manual recording, and only a single data of a certain point is selected in data processing, the data is discontinuous and there are human clerical errors, and the final The result is large measurement errors and low accuracy. Contents of the invention [0003] The purpose of the present invention is to provide a shaft rotation stiffness detection device to solve the problem of using simple mechanical hanging weights to detect the shaft stiffness in the prior art, resulting in large measurement errors and low accuracy of the detection results The problem. [0004] To achieve the above object, the present invention provides ...
