| 摘要 |
The invention relates to a sensor arrangement for monitoring a spindle bearing state, in particular a rapidly rotating high-accuracy spindle provided with prestressed bearings comprising two concentrically arranged sensor rings (11,13), wherein the internal sensor ring (11) in operation rotates with the spindle shaft (15) in relation to the external sensor ring (13), each sensor ring is provided with at least one sensor (17,19) for a monitorable bearing parameter and a transmission device, in particular a coil, of a transmission system, which are integrated therein for contactlessly transmitting energy and signals between said two sensor rings. |
