What are the technical advantages of high speed diaphragm couplings

Preface:

The high speed diaphragm coupling produced by mechanical manufacturers belongs to a kind of high performance metal strong component flexible coupling, it in the production process by several groups of diaphragm with bolts staggered and two half coupling, each group of diaphragm by several pieces of overlapping, diaphragm is divided into connecting rod type and different shapes of the whole plate type, is widely used in various mechanical devices of the shafting drive.

Xiaobian next ask you to explain the high speed diaphragm coupling has four technical advantages:

1, dry coupling, no lubrication: elastic diaphragm coupling relies on metal diaphragm to transfer torque and absorb deformation caused by misalignment, there is no relative movement between parts, no friction and wear, so there is no need for lubrication, in line with the process of oil-free equipment development direction;

2, all metal structure, large torsion transmission capacity, long service life: diaphragm coupling using metal diaphragm as an elastic element, high strength, large load transfer capacity, and the whole product does not exist non-metallic parts, no aging problem, long service life, compared with non-metallic elastic element coupling, diaphragm coupling is more suitable for harsh use environment;

3, compensation misalignment ability, easy to install, the type of good diaphragm coupling with high strength austenitic stainless steel diaphragm, can be in torsion at the same time to bear large deformation, so as to compensate the misalignment of two shafts;

4. Low axial and angular stiffness, small influence on equipment: diaphragm coupling adopts very thin metal diaphragm as an elastic element, low angular and axial stiffness, so the additional axial force and additional bending moment is very small. Because the gear coupling tooth surface can be relative slip, so people often feel that the gear coupling can compensate for greater angular and axial misalignment, without additional effects on the unit.

To sum up:

High speed diaphragm coupling is suitable for use in the process of process power equipment, we should understand the following two problems: reasonable to determine the transfer torque and thermal estimation. We also need to note that the type selection of diaphragm coupling should be based on the machine type provided by the complete set of manufacturers or host manufacturers and the shaft power under normal conditions, and should not be added layer by layer. However, there are occasions when other conditions should be considered. The selected coupling should be able to adapt to the larger continuous speed of the unit 1100. The working speed of the unit is different, the material selection, structural design, processing accuracy, dynamic balancing accuracy and other requirements of the coupling are different, so when choosing the coupling should check whether the larger allowable speed of the model can meet the requirements of the unit.
