Knowledge sharing: Chain rail is the key part of paver. It has to bear the huge working tension of periodic pressure in the use process. The quality of chain rail directly affects the service life of track assembly. There are internal resistance in crawler walking mechanism: 1. friction in the hinges of each chain rail joint; 2. friction between driving wheel and chain rail when meshing; 3. friction between guide wheel and chain wheel bearing; 4. friction of supporting wheel bearing and rolling friction of supporting wheel on chain rail.
