Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0025] refer to Figure 1-3 , a method for laser detection and early warning of eccentric rotation of a rotating shaft, comprising the following steps:

[0026] A. Horizontal adjustment: Loosen the launch lock cap 42 and the receiver lock cap 52, move up and down to adjust the launch adjustment lever 41 and the reception adjustment lever 51, and then rotate the launch positioning piece 61 and the receiving positioning piece 71 to make the launching positioning piece 61 and the receiving positioning piece 71 contact the surface of the rotating shaft horizontally, and lock the launching lock cap 42 and the receiving lock cap 52;

[0027] B, start detection; start host...

Abstract

The invention discloses a rotating shaft eccentric rotation laser detection early warning method, which comprises the following steps: horizontal adjustment; detection starting; eccentricity detection; and critical early warning. The laser detection early warning equipment used in the rotating shaft eccentric rotation laser detection early warning method comprises a main machine, wherein a transmitting supporting rod and a receiving supporting rod are symmetrically installed on the upper surface of the main machine, and a transmitting adjusting sliding groove and a receiving adjusting slidinggroove are formed in the transmitting supporting rod and the receiving supporting rod respectively. According to the invention, the initial positions of the laser transmitter and the laser receiver are quickly positioned through the transmitting positioning sheet and the receiving positioning sheet, so that the detection precision is improved; and the eccentric angle is calculated by detecting thetime when the laser receiver does not receive the laser signal of the laser transmitter in a unit period in real time, and the eccentric angle is compared with a preset value to output a result, so that the functions of real-time detection and timely alarm of eccentric rotation of the rotating shaft are achieved, and limitation of a magnetic field and a distance is avoided.

Description

technical field [0001] The invention relates to the field of mechanical transmission detection, in particular to a laser detection and early warning method for eccentric rotation of a rotating shaft. Background technique [0002] The rotating shaft is one of the main technical means of mechanical transmission. Most of the mechanical transmission rotating shafts are driven horizontally, so the rotating shaft transmission is greatly affected by the gravity of the transmission components and the load. Heavy loads or transmission components will bend after rotation. The bending of the rotating shaft will reduce the rotating efficiency and damage other mechanical parts. Therefore, the rotating shaft needs to be inspected frequently to facilitate timely replacement. [0003] The existing rotating shaft bending detection method usually adopts the method of eddy current detection, and the low-frequency electromagnetic wave or high-frequency electromagnetic wave of the eddy current s...
