Ceramic rapper rod assembly

Abstract

Electrostatic precipitators and other devices requiring vibration may be required to operate in high temperature environments, have a high dielectric strength, and withstand impacts that range into thousands of foot-pounds per second at a high repetition rate. In the present invention, a transmission or rapper rod is employed including tapered ends, that are too short to bottom in the corresponding mounting sleeves, and further including a pair of thin, malleable metallic shims between the tapered ends and the sleeves acting to accommodate dimensional tolerances and distinct surface finishes, thereby eliminating fracture-inducing impacts.
