Bearing device having a sensor for measuring the vertical bearing force of a rotating shaft

摘要

A bearing device for bearing a shaft having a bearing, a supporting structure for supporting the bearing and at least on piezoresistive sensor incorporated in the supporting structure in an integrated manner which is arranged in the flux region of the bearing apparatus is provided. The electrical resistance of the sensor is influenced by the vertical force of the bearing having effect on the sensor such that the vertical force of the bearing may be electrically tapped on the sensor. A corresponding method for determining the static and/or dynamic vertical bearing forces of the shaft bearing of a shaft and a rotor system for determining the vertical bearing force of a shaft bearing are provided.

1. A bearing device for bearing a shaft, comprising:
a bearing; a supporting structure, with a stool plate for supporting the bearing; and a piezoresistive sensor which is fitted in an integrated manner into the stool plate and is arranged in a power flow area of the bearing device, wherein the electrical resistance of the piezoresistive sensor is influenced by the contact force of the bearing, which acts on the piezoresistive sensor, such that the contact force of the bearing is tapped off electrically at the piezoresistive sensor.
