Published: 2017-12-15

With the development of industry and science and technology, flexible couplings are being used for their unique functions in terms of performance, workability, extension of equipment life, vibration reduction, buffering, noise reduction, energy saving, and improvement of transmission efficiency of the entire transmission system. More and more scientific and technical personnel know it.

Coupling is a device that connects two shafts or shafts and rotating parts, and rotates together without disengaging during the process of transmitting motion and power (torque). During the transmission process, the direction of rotation and the magnitude of the torque are not changed. It is the common function of all kinds of couplings.

Various types of couplings have different functions and roles in the transmission system, 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 shafting transmissions of mechanical products such as ships, machine tools, water pumps, fans, and compressors, whose 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 high torque rigidity. Generally, metal elasticity is used. Components, the relative torsion of the two halves of the coupling causes the error of angle transmission.

The development of science and technology and industry has led to the development of high-power, high-speed, high-temperature, and vulgar, heavy-duty mechanical products and mechanical equipment. Corresponding to the function and role of the transmission system coupling under these conditions, a new comprehensive Requirements, in addition to connecting the two shafts to transmit torque or motion, it is also required to compensate for the relative offset of the two shafts, reduce vibration, buffer, improve transmission efficiency, improve transmission accuracy, reduce noise, energy saving, and drive system performance. The shaft device is simple in structure, good in process performance, high in performance, easy to manufacture, easy to maintain, easy to assemble and disassemble, and the half coupling does not need to move the axis when changing the wearing parts. According to the requirements in product design, scientific and technical personnel continue to develop Produce flexible couplings with various characteristics to meet the needs of the transmission system of Manzi's different mechanical products.
