Rotary assembly for use in industrial application, has rolling unit staying in contact with track driven by drive unit, where running nose at rotary assembly is measured as airborne noise and has sound pressure level

摘要

The assembly has an electromotive drive unit (3) and an antifriction bearing (2) that includes a rolling unit arranged around a rotational axis (2a) of the bearing. The rolling unit stays in contact with a track (5) driven by the drive unit (3). A running nose at the rotary assembly is measured as an airborne noise and has a sound pressure level with a largest value of 72 decibel.
