Because of this, rubbing systems must control various operating conditions and demands, as well as minimizing clearance. Therefore, there are special requirements for rubbing systems. For example, rubbing must only occur in such a way that consequential damages are kept to a minimum. The turbine-side rotor must be braked in case of shaf…
