A dynamic model for a new principle of percussive-rotary drilling is presented. This is a non-linear mechanical system with two degrees of freedom, in which friction-induced vibration is used for excitation of impacts, which influence the parameters of stick-slip motion. The model incorporates the f
ary seal assembly. This enables the mechanical seal to be fitted to equipment where the shaft is out of alignment with the equipment casing. This ability to accommodate angular variation can be achieved without any consequential misalignment of the sealing faces of the seal.
