The bearing assembly with a hob TBM composite sensor

TBM bearing assembly of the present invention belongs to the composite sensor hob with tunneling machine art, it relates to a composite of the plurality of sensor devices employed, and bearing integrally and effective extraction of the boring machine bearing failure signal hob bearing assembly. The composite sensor device by a tapered roller bearing assembly is mounted on bearings and is integral bearing; composite by a variety of sensors and sensor means integrally adapter ring; more sensors an acceleration sensor, a temperature sensor, a speed sensor is configured, these sensors are embedded transition ring, and through the respective output signals of the sensor cable. After the integration of the bearing assembly capable of real-time monitoring their work performance. And after a failure, the ability to transmit an alarm signal to the machine control system, early detection of early bearing failure to take timely measures to improve the working life of the bearings and hob. It can be produced and sold as a standalone product, user-friendly use.
