Ratio piezoelectric type rotating shaft eccentricity detection and early warning equipment

Abstract

The invention discloses ratio piezoelectric type rotating shaft eccentricity detection and early warning equipment which comprises a fixing plate and a detection pipe, a plurality of first detection grooves and a plurality of second detection grooves are annularly and symmetrically formed in the inner wall of the detection pipe, a first piezoelectric plate and a second piezoelectric plate are installed in each first detection groove and each second detection groove respectively, a sealing cover is mounted at the opening of each of the first detection groove and the second detection groove, anda detection rod is inserted into each sealing cover in a sliding manner. The equipment is simple and ingenious in structure, change of the rotating radius of the rotating shaft caused by the bendingangle of the rotating shaft is detected through the first piezoelectric plate and the second piezoelectric plate, detection of the bending degree of the rotating shaft is realized, non-stop real-timedetection and early warning are realized by sleeving the detecting pipe on the rotating shaft, and the accuracy and reliability of the detection and early warning are improved.

Description

technical field [0001] The invention relates to the field of rotating shaft detection, in particular to a ratio piezoelectric type rotating shaft eccentric detection and early warning equipment. Background technique [0002] Automated mechanical equipment is a high-efficiency electrified equipment commonly used in processing today. During the production and processing of automated mechanical equipment, transmission between various parts is required, and shaft transmission is a more common high-efficiency transmission method in actual use. The shaft will be affected by itself during transmission. The gravity and the gravity of the connecting parts cause bending, but the degree of bending is very small and does not affect the use, but in some heavy loads, the shaft is under heavy force, and the bending degree continues to increase as the use time increases , when the shaft is bent to a certain extent, it will cause damage to the shaft itself and accessories such as connectors,...

[0002] Automated mechanical equipment is a high-efficiency electrified equipment commonly used in processing today. During the production and processing of automated mechanical equipment, transmission between various parts is required, and shaft transmission is a more common high-efficiency transmission method in actual use. The shaft will be affected by itself during transmission. The gravity and the gravity of the connecting parts cause bending, but the degree of bending is very small and does not affect the use, but in some heavy load cases, the shaft is under heavy force, and the bending degree continues to increase as the use time increases , when the shaft is bent to a certain extent, it will cause damage to the shaft itself and accessories such as connectors, so it needs to be scrapped and replaced

[0003] The existing bending detection of the rotating shaft usually uses human eyes to observe the straightness and straightness, and the judgment accuracy is low, while the machine detection needs to disassemble the rotating shaft for detection, which affects the normal working machinery, and cannot timely alarm the rotating shaft that reaches the bending limit during work. prone to mechanical damage
