Introduce:

A diaphragm coupling is a common mechanical transmission typically used to connect two rotating shafts. It is composed of two metal sheets inside and outside intersecting each other, fixed on the shaft by bolts or nails and other parts. Diaphragm couplings transmit torque and rotational angles while also absorbing small misalignments and vibrations between the shafts.

The working principle of a diaphragm coupling is very simple:

When the two shafts rotate, the shape of the two thin plates inside and outside the diaphragm coupling will change slightly, so that the relative position and angle between the two shafts will change. This change creates a certain elastic deformation that transmits the torque to the other shaft. At the same time, the structure of the diaphragm coupling can also ensure the stability and reliability of the transmission by absorbing the small deviation and vibration between the shafts. The design and manufacture of diaphragm couplings need to consider many factors, such as transmission power, speed, angular displacement, axial displacement, vibration and temperature. Therefore, different types of diaphragm couplings have different shapes, sizes and materials to suit different working conditions and needs.

Summarize:

In industrial production, as a common transmission device, diaphragm couplings are widely used in mechanical equipment, aerospace, automobiles, petroleum and chemical industries. Its advantages lie in its simple structure, high transmission efficiency, high reliability, long service life and convenient maintenance. At the same time, with the continuous development of science and technology, more and more new diaphragm couplings are emerging, providing more choices and possibilities for the development and progress of industrial production.
