For large flanges used in engineering machinery, controlling deformation and hardness during heat treatment is a key step in ensuring their mechanical properties and service life.

In the complex transmission and execution systems of engineering machinery, the stable operation of hydraulic cylinders, piston rods, and other reciprocating or rotating moving parts relies on a seemingly small but crucial component—the guide bushing.

From the perspective of material properties, the elastic modulus and yield strength of the ring gear and shaft are the basic parameters for interference fit design.

Rubber gaskets or flexible graphite gaskets are easily compressed, so the torque needs to be appropriately reduced to prevent excessive compression from causing failure.

In the hydraulic and motion systems of heavy construction machinery such as excavators, loaders, cranes, and tunnel boring machines, countless high-load, high-frequency reciprocating or rotating movements rely on precisely matched mechanical structures.

The continuous vibration caused by imbalance can lead to loosening of shaft components and even catastrophic failures such as gear breakage.
