Generally speaking, rolling bearings installed with tight fit interference must be close to the shaft shoulder. So how to test it? (1) Lighting method. This method is to aim the light at the bearing and shaft shoulder, and judge according to the light leakage. If there is no light leakage, the insta... read more
The operating environment of wind turbines is very harsh and the stress conditions are complex. There are many types of gearboxes for wind turbines. The following example mainly refers to the analysis of the output gear shaft fracture of the wind power speed increaser during operation. According to ... read more
The deterioration of rolling bearings is not a linear process, but an exponential process. In different degradation stages, the fault information appears in different frequency bands, so different fault detection methods must be adopted. At present, the industry generally believes that the degradati... read more
