    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.

    摘要： A rolling bearing is intended to be mounted on a machine and includes a first ring, a second ring, and at least one row of axial rolling elements and at least one row of radial rolling elements arranged between the two rings. Each of the first and second rings has two frontal faces axially delimiting each ring. At least the first ring is formed as a split ring including a first ring part and a second ring part axially stacked, the first ring part having a frontal face axially bearing against a facing frontal face of the second ring part. At least one first distance sensor is mounted on one of the first and second ring parts of the first ring to measure an axial distance between the frontal faces of the two ring parts.

    摘要： Improved bearing roller elements are disclosed. A first disclosed improvement is the addition of vanes to a ring-roller type element which allows fluids (such as liquids or gases) to flow through the bearing assembly. The fluids can then provide convection cooling. With proper configuration, the use of such vaned ring-roller elements can even allow the creation of a pump, either as part of the larger apparatus' cooling system or as a dedicated device. A second disclosed improvement, which can be used in combination with the first or in isolation, is the use of magnetic spokes in ring-roller type elements which allows them to be driven by an electromagnetic field. The use of such magnetic elements in the bearing roller elements also allows electromagnetic braking and/or regenerative braking.A bearing assembly incorporating the roller elements in a ring configuration and using pre-load to produce additional benefits is also disclosed.

    摘要： A electric swivel, LVES, in a swivel stack, includes an annular outer element defining a cylindrical chamber around an axis S and an cylindrical inner element coaxial with the outer element. The cylindrical chamber is sealed at an upper side with an annular cover and is configured for rotation relative to the inner and outer element around the axis S. The inner element includes at an inner radial side first and second bearing parts defining an inner bearing. The outer element includes at an outer radial side first and second bearing parts defining an outer bearing. The inner bearing includes an inner annular interface between the first and second bearing parts, the outer bearing includes an outer annular interface between the first and second bearing parts. Each of the annular interfaces is coaxial with the inner and outer element, and each annular interface is configured as a flame conducting path.
