Arrangement of grinding modules with grinding tools in track grinders

摘要

An arrangement of grinding modules in a track grinder wherein a radial mismatch in narrow track bend radii can be considered in an exact manner without occurrence of constraining forces, enabling reprofiling to be reproduced in a simple manner. The arrangement provides a grinding tool with five degrees of freedom. Each grinding module is accommodated in an at least approximately vertical manner with a frame and in an at least horizontally manner on the frame with a holder. A housing in the holder is pivotably arranged around a shaft that is at least approximately parallel to the track to be ground. The grinding tool in the housing can be adjusted in a rectangular manner in relation to the track to be ground.
