A load sensing device comprises a support mounted on a foundation, and a bridge connected to the support. The bridge is connected to a transducer. In order to ensure that the same transducer can be used for all sizes of supports in a particular series of supports, or for all loads to be measured, the transducer is flexibly connected to the support, and the stiffness of the connection between the bridge and the support and the stiffness of the flexible connection between the transducer and the support are both selected so that the load exerted upon the transducer always lies within a predetermined load range.

Load sensing device

In a bearing mounting for flexible rotors there are provided bearing heads for the journals of the flexible rotors and a foundation to support such bearing heads. For the purpose to influence the natural frequency of the combined system rotor - rotor support which is dependent also on the support stiffness it is desirable to change the support stiffness in the simplest possible manner in such a way that starting from the effects of the flexible rotor to be treated on the signal pick-ups, a control and/or closed loop control of counter-effects is possible to find the balancing quality of a flexible rotor independent of the present support stiffness.

Balancing machine bearing mounting for flexible rotors

A procedure and a device are provided for determining the correlation between the unbalance of a rotor in at least one correction plane thereof and the measurement signal generated by such unbalance at one or more of the rotor supports. The vibration signals of the rotor are measured at different bearing support stiffness.
