Mechanical seals, as one of the most critical sealing components in rotating equipment, are widely used in structures such as pumps, compressors, gearboxes, and reactors. Their function is to prevent the leakage of media (such as oil, water, and gas) along the rotational axis. Due to the complex ope

In high-load, high-intensity operating conditions, the surface strength and fatigue resistance of gear components are crucial to the reliability of the entire system. In addition to conventional heat treatment methods, gear roll strengthening (Roller Burnishing /Cold Rolling), as a non-cutting, mate

As the most common way of mechanical connection, interference fit is widely used in high load parts such as shaft and hub, bearing inner ring and shaft, gear installation, train wheel pressing and so on. It forms a tight fit through the interference between parts to achieve reliable torque or axial

In the mechanical assembly structure, pin connection (Pin Connection) is one of the most commonly used precision positioning means. It is widely used in heavy equipment, gearboxes, couplings, machine tool benchmarks and other fields because of its advantages of simple structure, convenient manufactu
