MEASUREMENT ON ROLLING ELEMENT GEARS

Problem: Disruptions in production

Goal: Reliable gearbox design

Vibrations in paper machine gearboxes can impair paper quality and lead to frequent tears in paper feed. These rotational energies occur in the rolling element gear unit, in which rollers and cylinders (rolling elements) are combined. The transmission of torque and motion is based on the principle of frictional locking. When rolling elements are used to guide material, they must transmit a rotational motion that is as uniform as possible to ensure precise positioning of the material to be guided as well as roll parallelism. This is also the case with printing machines, where ink is applied to a material in several layers.

Torsional vibrations can also correlate with the torque signal. To analyze this, the rotational speed is recorded with a rotary encoder at the input and output shaft. The structure-borne sound signals are recorded with an accelerometer on the roll housing. Finally, the recorded measured values are evaluated in the time and spectral range and the acoustic behavior is analyzed.

The recorded measured values are evaluated in the time and spectral domain. The acoustic behaviour is also analyzed.

Furthermore ROTEC ENGINEERING provides you with support and technical engineering know-how for problems related to vibration analysis of engines, transmissions and drive trains.
