The frequency of support vibrations is low and similar to the rotation frequency of the rotary drum. Any deformation of the shell results in incorrect operation of the open gear which is a component of the rotary kiln drive. It is a kinematic pair consisting of a toothed ring, mounted on the rotary drum shell and a pinion coupled via a flexible coupling with an output shaft of a reduction gear. The frequency of those constraints is higher, similar to the open gear mesh frequency. Variable clearance, both inter-teeth and tip clearance, mainly due to synchronous precession of the toothed ring and wear of the meshing teeth surface induces the rotary drum vibrations, which are transferred to the support via a ring - roller system.
