    摘要: The present disclosure relates to a rotating equipment monitoring device. The rotating equipment monitoring device includes a housing having a first accommodating space and a second accommodating space. The second accommodating space is located at an end of the housing and is separated from the first accommodating space. A sensor assembly is arranged in the first accommodating space. The first accommodating space is filled with an explosion-proof medium that completely surrounds the sensor assembly. An antenna communicates with the sensor assembly and is arranged in the second accommodating space. A cover is installed on the housing via a cover installation portion at an end of a sidewall of the housing to seal the antenna in the second accommodating space.

    摘要: A wear monitoring method of a polymer thrust bearing based on an ultrasonic reflection coefficient amplitude spectrum (URCAS), includes: selecting a corresponding delay block probe based on a material of a to-be-tested bearing, and setting corresponding parameters of a pulse generator; after collecting a primary echo from a surface of the delay block probe as a reference signal, placing the delay block probe in a designated region on a back of the to-be-tested bearing, and collecting time-domain echo signals from upper and lower surfaces of the bearing; establishing a propagation model of an ultrasonic signal in a polymer bearing, and calculating a theoretical URCAS based on the propagation model; calculating a measured URCAS; and constructing an objective function, and solving the objective function by using a differential evolution algorithm. A plurality of parameters of the polymer bearing is solved to meet a requirement for wear monitoring by adopting the method.

    摘要: A sensorized rolling element for a bearing having inner and outer races and a plurality of rolling elements disposed between the inner and outer races and includes a rolling element body having an interior surface defining a cavity, the body being disposable between the inner race and the outer race. A wireless transmitter is disposed within the cavity of the rolling element body and a piezoelectric device is disposed within the cavity so as to contact the inner surface of the rolling element body. The piezoelectric device includes a body formed of piezoelectric material and at least two electrodes electrically coupling the piezoelectric body with the wireless transmitter. The piezoelectric device is configured to generate electrical charge for powering the transmitter when the rolling element body deflects under loading applied by the inner race and/or outer race and may also be used to detect loading on the rolling element body.
