Coupling Supplier

The coupling is a key component that connects two shafts in mechanical transmission. Its core functions include transmitting torque, compensating for shaft deviation (axial, radial, angular) and buffering vibration and shock. Among the common types, the plum blossom elastic coupling (such as GM type) adopts polyurethane elastomer and metal claw disc structure. The elastomer is only under pressure, with high load and long life characteristics, suitable for medium and high speed scenes such as pumps and fans; the diaphragm coupling uses a metal diaphragm group to achieve wear-free transmission, high temperature resistance (-80~300℃), outstanding compensation ability, and is suitable for high-speed and high-power systems such as generator sets; the drum gear coupling optimizes contact stress through drum teeth, has strong load-bearing capacity but requires lubrication, and is mostly used in heavy-load environments such as metallurgy, mining, fans, and electricity; the universal coupling achieves multi-directional angle compensation through a cross shaft or ball joint structure, which is suitable for complex transmissions such as engineering machinery. In addition, the safety coupling integrates an overload protection mechanism, and the hydraulic coupling achieves soft start through a fluid medium to meet specific working conditions. The selection needs to comprehensively consider the torque range (such as GM type 25~12500Nm), speed (diaphragm type can reach tens of thousands of rpm), environmental adaptability (temperature, corrosion) and maintenance cost (maintenance-free or regular lubrication). It is widely used in industrial machinery, energy equipment, transportation and other fields, and is a core component to improve transmission efficiency and reliability.
