CouplingIt is a device that connects two shafts or a shaft and a rotating part, and rotates together without disengaging during the process of transmitting motion and power (torque). It does not change the direction of rotation and the magnitude of torque during the transmission process. This is a variety of The common function of the coupling.
VariousCouplingThe functions and roles in the transmission system are not the same, but the common basic role is to transmit torque and motion.Therefore, the amount is relatively wide, such as: heavy machinery, metallurgical machinery industry, mining machinery, construction machinery, agricultural machinery, petroleum machinery, chemical machinery, lifting and transportation machinery, textile machinery, light industry machinery, printing machinery, automobiles, tractors, locomotives, Couplings are used in shaft transmissions of mechanical products such as ships, machine tools, water pumps, fans, and compressors, and their main function is to transmit torque.
It is applied to the couplings of machinery, control, control mechanism and instrument equipment. The torque is very small. The main function is to connect two shafts and transmit motion. It requires high transmission accuracy and should have high torque rigidity. Generally, metal elasticity is used. Components to eliminate the angle transmission error caused by the relative torsion of the two halves of the coupling.With the development of industry and technology, flexible couplings have the functions of improving the working performance of the entire transmission system, ensuring the reliability of the work, extending the service life of the equipment, reducing vibration, buffering, reducing noise, energy saving, and improving transmission efficiency. It is being recognized by more and more scientific and technical personnel.
The development of technology and industry has promoted the development of high-power, high-speed, high-temperature, high-precision, vulgar, heavy-duty mechanical products and mechanical equipment. Corresponding to the function and role of the transmission system coupling under these special working conditions, it is proposed In addition to connecting two shafts to transmit torque or motion, it also requires compensation for the relative offset of the two shafts, vibration reduction, buffering, improvement of transmission efficiency, improvement of transmission accuracy, reduction of noise, energy saving, and improvement of transmission system work. Performance, and requires the coupling structure to be simple, good process performance, high reliability, easy to manufacture, low size, easy to maintain, easy to assemble and disassemble, the half coupling does not need to move the axis when replacing the wearing parts, etc., for the product The requirements are put forward in the design, and domestic and foreign scientific and technical personnel have continuously developed flexible couplings with various characteristics to meet the needs of the transmission system of Manzi's different mechanical products.
