1. Overview of CouplingsA coupling is a key mechanical component designed to connect two shafts (such as the output shaft of a motor and the input shaft of a working machine) in power transmission systems. Its core functions include transmitting torque, compensating for relative misalignments betwee

Typical data shows that when axial clearance is 10%–20% below the recommended value, the bearing's service life can be reduced by 40%–60% due to excessive contact stress and lubrication failure. Conversely, a clearance 30% above the optimal range only shortens life by 10%–15% and mainly affects oper

Wind turbine gearboxes are one of the core components in wind power generators, located between the rotor and the generator. They undertake the crucial task of converting the low-speed mechanical energy captured by the rotor into the high-speed mechanical energy required by the generator. As the "tr

In the manufacturing of machined parts and tooling dies, heat treatment is a critical step. Among the various processes, normalizing and annealing are the most common preparatory heat treatments, typically performed after casting or forging and before rough machining. For some components with low pe
