Abstract: A method for detection and quantitative evaluation of a balance error occurring in a component-bearing system. Static and dynamic forces acting upon the bearing are determined by sensors of a measuring bridge, which are disposed on a rolling bearing and which change the inherent electrical resistance according to the applied pressure, and are made available for analysis in a computer in the form of a periodic test signal that is common to both forces. In order to analyze the test signal, the weighted average of the modulation frequency generated by a balance error and the weighted mean variance thereof are determined from the test signal. The variance is then compared with a given variance threshold value. A variance lying below the variance threshold value is considered to be an indication of a significant balance error in the bearing.

Abstract: To supply a powder lacquer sprayer, the coating powder is pressed by a pig through the supply line and, in the process, it is fluidized from the side of the pig which is turned toward the powder. The fluidization air can be led to the powder, for example, by a central passage opening of the pig or through an air permeable wall of the connection line. For the dosage of the coating powder, one uses the push medium which drives the pig.

Abstract: A method for detection and quantitative evaluation of a balance error occurring in a component-bearing system. Static and dynamic forces (F<SB>S>/SB>, F<SB>U</SB>) acting upon the bearing are determined by sensors of a measuring bridge, which are disposed on a rolling bearing and which change the inherent electrical resistance according to the applied pressure, and are made available for analysis in a computer in the form of a periodic test signal that is common to both forces. In order to analyze the test signal, the weighted average of the modulation frequency generated by a balance error and the weighted mean variance thereof are determined from the test signal. The variance is then compared with a given variance threshold value. A variance lying below the variance threshold value is considered to be an indication of a significant balance error in the bearing.
