The material selection of motor coupling is often made of metal materials, such as cast iron, steel, etc. Cast iron has low cost and good casting performance, and is suitable for occasions where the strength requirements are relatively low and the load is relatively stable. Steel couplings have high strength, good toughness, and can withstand large torque and impact loads, and are mostly used in heavy-duty, high-speed or application scenarios with high reliability requirements. Some elastic couplings will also use rubber, polyurethane and other elastic materials, these materials have good elasticity, wear resistance, can effectively absorb vibration and impact energy, and have good oil resistance and aging resistance, to ensure that they play a stable role in different working environments.
Function and application
The core function of the motor coupling is to transmit torque and motion to ensure that the power of the motor is efficiently and stably transmitted to the working machine. In the process of transferring torque, it can compensate the radial, axial and angular displacement between the two axes, and reduce the influence of installation errors or shaft deformation and vibration during the working process on the transmission system. In the industrial field, motor couplings are widely used in all kinds of mechanical equipment. In the automatic production line, it connects the motor with the transmission mechanism to ensure the stable operation and accurate transmission of the production line. In automobile manufacturing, it is used for power transmission between engine and transmission to adapt to various working conditions in the process of vehicle driving; In a wind power system, the coupling connects the wind wheel to the generator, efficiently converting the wind energy captured by the wind wheel into electricity, while coping with the vibration and shock caused by changes in wind conditions.
