Bearing acoustic detection device

The invention relates to the technical field of bearing fault detection, in particular to a bearing acoustic detection device. Comprising an acoustic detection device and two bottom plates, the tops of the two bottom plates are each fixedly provided with a plurality of second damping springs, the tops of the second damping springs make contact with the bottom of the acoustic detection device, a fixing cross rod for connecting the two bottom plates is fixedly installed between the two bottom plates, and the fixing cross rod is sleeved with a transverse damping mechanism; two lifting supporting mechanisms are arranged at the top of the fixed cross rod and located on the two sides of the transverse vibration reduction mechanism correspondingly. The lifting support mechanism is used for providing certain support force for the acoustic detection equipment; the transverse vibration reduction mechanism comprises a third vibration reduction spring, two sliding blocks and two first transmission rods.
