    • A tapered roller bearing having its rollers arranged in two rows within an outer race and around an inner race contains a sensing device that radiates signals which reflect conditions within the bearing. In one embodiment, the outer race is unitary and the sensing device is wireless and self-powered and includes a mounting ring that is fitted to the outer race between the raceways along which the rollers roll. The ring has embedded within it several sensors for monitoring bearing conditions such as temperature and vibrations. The ring also contains a radio transmitter, a microprocessor to which the sensors are connected, and a power supply for producing the electrical energy required to operate the processor and the transmitter. The electric power is generated by means of electromechanical energy conversion using permanent magnets, armature winding and a target wheel that is captured between and rotates with the two cones. The transmitter converts conditions registered by the sensors and processed by the processor into radio signals which are received externally from the bearing. In another embodiment the unitary outer race has a groove which opens inwardly between the two rows of rollers, and the sensors, radio transmitter, processor, and power supply are located within the groove. In other embodiments the inner race is unitary and the sensors, radio transmitter, processor and power supply are carried by the inner race.
    • 一种圆锥滚子轴承,其具有在外座圈内和围绕内圈布置成两列的滚子,其包含辐射反映轴承内的条件的信号的感测装置。 在一个实施例中,外座圈是一体的,并且感测装置是无线的并且是自供电的,并且包括安装环,所述安装环装配到滚子滚动的滚道之间的外圈上。 环内嵌有几个传感器,用于监测温度和振动等轴承条件。 该环还包含一个无线电发射机,一个与传感器连接的微处理器,以及用于产生操作处理器和发射机所需的电能的电源。 电力通过使用永磁体,电枢绕组和被捕获在两个锥体之间并与之旋转的目标轮的机电能量转换而产生。 发射机将由传感器注册并由处理器处理的条件转换成从轴承外部接收的无线电信号。 在另一个实施例中,整体外圈具有在两排辊之间向内开口的凹槽,并且传感器,无线电发射器,处理器和电源位于凹槽内。 在其他实施例中,内圈是单一的,并且传感器,无线电发射器,处理器和电源由内圈承载。
