What is the structural principle of the high-speed diaphragm coupling

Installation of diaphragm coupling:

Couplings with diaphragms usually have edges and there is a risk of scratches. It is recommended to wear thick protective gloves and other protective measures during installation. When installing the diaphragm coupling, install a protective cover and other devices nearby to confirm. Pay special attention to the error of the shaft center during installation. If the error exceeds the allowable value, the diaphragm coupling is likely to be deformed during operation, resulting in damage or shortened service life.

The shaft center deviation of the diaphragm coupling includes the three deviations of radial direction, angular direction and axial direction. When installing, it should be properly adjusted to ensure that the shaft center deviation is within the allowable value range of the corresponding product catalog. When there are multiple deviations, the corresponding rated allowable value should be halved. In order to prolong the service life of the diaphragm coupling, it is recommended to set the shaft center error within one-third of the allowable value.

The structural principle of the high-speed diaphragm coupling:

It is a normal phenomenon that the shaft diameters of the driving and driven ends are different. When the torque and speed are the same, but the shaft diameters of the driving and driven ends are not the same, the coupling type should be selected according to the large shaft diameter. In the newly designed transmission system, seven types of shaft holes that meet the requirements in GBT3852 should be selected. It is recommended to use the J1 type shaft hole type to improve versatility and interchangeability. Diaphragm coupling cross shaft universal coupling, if it is compared with ordinary universal coupling, the outstanding advantage of this kind of universal coupling is that it can be connected in different places. The two rolling shafts on the center line, and normally open the transmission of the torque and open the movement, so as to achieve the purpose of use and the best use effect. Different types of couplings must be different. For example, universal couplings use lubricating fluid, while pulse dampers and plum blossom couplings do not need to use lubricating fluid. In addition, the shock absorption, wear resistance and buffering characteristics of the plum blossom coupling are superior to the diaphragm coupling. The diaphragm coupling is a coupling in which several sets of diaphragms, that is, stainless steel sheets, are interlaced through bolts and the like.

Compensation principle of diaphragm coupling diaphragm:

The diaphragms of each group of the diaphragm coupling are stacked with several diaphragms. The diaphragm is divided into two different methods: connecting rod type and integral type. The compensation principle of the diaphragm coupling is to rely on the elastic deformation of the diaphragm to compensate the relative displacement it produces. The service life of the diaphragm coupling is good, the structure is relatively compact, it is not affected by temperature and dirt, and it is relatively good in resisting acid and alkali. It is a shaft transmission system suitable for corrosive industrial drawings. The compensation principle of the diaphragm is: to compensate for the faults of the manufacturing equipment and the deformation bearing conditions generated when the machine is working, as well as the radial and angular offsets caused by the increase and decrease of the temperature. And because the diaphragm coupling belongs to the flexible coupling of elastic elements, it has the characteristics of elastic cushioning, no noise and no smoothness, etc. It is the ideal product of a general coupling at present. The production of diaphragm coupling is composed of at least two sleeve shafts or one diaphragm. Since the diaphragm is nailed to the sleeve shaft, there will be no looseness or gap between the two diaphragms under normal circumstances. conflict with each other.
