Long span diaphragm couplings have a strong torque transmission capability and can continuously and stably transmit large torque to ensure the normal operation of high-precision equipment.

Secondly, the coupling can withstand high speeds，meeting the needs of high-speed equipment. In addition, the long-span diaphragm coupling can withstand large deviations in the X, Y, and Z directions, ensuring the stability and reliability of the equipment under various complex working conditions.

At the same time, it also has excellent properties such as wear resistance, high temperature resistance and corrosion resistance, and is suitable for various harsh environments.

long-span diaphragm coupling gives it excellent transmission performance and stability. It is mainly made of high-strength C45 steel, an intermediate sleeve made of carbon fiber tube, a flexible element composed of stainless steel diaphragms, and accessories such as clamping elements, bolts, and anti-loosening nuts.

The torque is input from the active half coupling, transmitted to the front flexible steel sheet group through high-strength bolts, and then transmitted from the flexible steel sheet group to the intermediate sleeve through high-strength bolts, and output by the rear flexible steel sheet group, high-strength bolts and driven half coupling.

This structure enables the long-span diaphragm coupling to eliminate offsets from multiple directions and ensure the stability and accuracy of transmission.

The material composition of the long-span diaphragm coupling is also an important guarantee for its excellent performance. C45 steel, as the main material of the half-coupling, has high strength and good mechanical properties, and can withstand the test of large torque and complex working conditions. Carbon fiber tube, as the material of the intermediate sleeve, has the characteristics of light weight, high strength, low friction, etc., which can reduce equipment load, reduce energy consumption and increase speed. Stainless steel diaphragm, as the key material of the flexible element, has excellent corrosion resistance and wear resistance, and can maintain stable transmission performance in various harsh environments. The combination of these high-quality materials makes the long-span diaphragm coupling perform well in transmission performance, service life and reliability.

Long-span diaphragm couplings are widely used in many fields due to their excellent performance. In the machine tool industry, they are widely used in high-precision machine tools such as cutting machines and grinders, and can maintain high-precision rotation and rotation to ensure the normal operation of the servo drive system. In the automotive industry, long-span diaphragm couplings are used in key parts such as automotive drive shafts and steering mechanisms to improve driving stability and reduce noise. In the aviation industry, they are widely used in flight control systems, aircraft engines and other equipment to meet the requirements of high precision and high reliability. In addition, long-span diaphragm couplings also perform well in general machinery, ships, energy and other fields.
