Abstract: A bearing fault diagnosis method based on a fuzzy broad learning mode includes steps of constructing an initial fuzzy broad learning model based on a broad learning system and a fuzzy system, training the initial fuzzy broad learning model through training set data to obtain a target fuzzy broad learning model. The training set data includes a plurality of bearing vibration signal data with a fault type label; and a membership value of a bearing vibration signal data to be tested is calculated by the target fuzzy broad learning model. A fault type of the bearing to be tested is determined based on the membership value. The bearing fault diagnosis method reduces learning time. When determining the fault type of the bearing to be tested by the target fuzzy broad learning model, it has strong robustness, fast diagnosis speed and high fault diagnosis accuracy.

Abstract: Provided is an adapter. The adapter includes a housing and an elastic component. The elastic component is configured to connect the housing with an installation frame. The elastic component includes an installation body, a blocking portion and a clamping elastic piece, the blocking portion and the clamping elastic piece are disposed on the installation body. The installation body is configured to be detachably connected to the housing. A first clamping gap capable of accommodating the installation frame is provided between the blocking portion and the clamping elastic piece.
