Research and Application of Surface Quenching Technology in Hydraulic Support
With the increasing development of hydraulic support design and manufacturing technology,the demand for the service life of hydraulic supports is becoming higher and higher.As the core parts of the hydraulic support action(friction),the movable column head of the column,the bottom surface of the outer cylinder,and several friction parts such as the articulated shaft between the top beam and the cover beam,the articulated shaft between the cover beam and the connecting rod,and the articulated shaft between the connecting rod and the base are the most critical parts that affect the service life of the hydraulic support.Based on past experience,the components in these areas of action(friction)are often severely damaged and difficult to repair.Therefore,improving the life of these friction parts is of great significance for the overall life of hydraulic support.
