Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings.
[0032] refer to Figure 1 to Figure 5 A method for dynamic centering of a high-speed shaft of a wind power generating set, the method comprising the following steps:
[0033] a) Set pulse trigger device and alignment detection device on the high-speed shaft of the gearbox;
[0034] b) Use the periodic pulse signal generated by the pulse trigger device to trigger the high-speed shaft alignment detection device of the wind turbine to measure the alignment data;
[0035] c) The high-speed shaft of the wind turbine unit measures the alignment data for a set number of times per rotation, and transmits the alignment data to the signal processing module through wireless transmission;
[0036] d) The signal processing module analyzes the measurement data to obtain the measured deviation values Δx, Δy, and Δθ. By comparing the measured deviation with the preset allowable de...
