Device for measuring forces generated by an unbalance |
摘要 |
A device for measuring forces generated by an unbalance of a rotor, said device comprising a stationary frame, a first bearing, measuring shaft mounted rotatably about its shaft axis in the first bearing, a mounting means provided on the measuring shaft designed for attachment of the rotor, wherein the rotor is designed to be balanced in at least one compensating plane, a second bearing pivotally supporting the first bearing about a pivot axis which intersects the shaft axis and being supported on the stationary frame, a first force sensor for measuring forces generated by the unbalance of the rotating rotor and acting about the pivot axis, and a second force sensor for measuring forces generated by the unbalance of the rotating rotor and acting on the measuring shaft and on the second bearing in a direction intersecting the shaft axis. |

1. A device for measuring forces generated by an unbalance of a rotating rotor, said device comprising:
a stationary frame; a first bearing; a measuring shaft mounted rotatably about its shaft axis in the first bearing; a mount provided on the measuring shaft designed for attachment of the rotor, wherein the rotor is designed to be balanced in at least one compensating plane; a second bearing pivotally supporting the first bearing about a pivot axis which intersects the shaft axis and being supported on the stationary frame; a first force sensor for measuring forces generated by the unbalance of the rotating rotor and acting on the measuring shaft about the pivot axis; and a second force sensor for measuring forces generated by the unbalance of the rotating rotor and acting on the measuring shaft and on the second bearing in a direction intersecting the shaft axis; and a first spring provided between the first bearing and the second bearing, the first spring including one or ore torsion springs. |
