Characteristics and application scenarios of double diaphragm couplings

   Double diaphragm couplingThe product is usually used in the connection between shafts, and can also be used to connect the motor and fan after the liquid coupling is removed.
   Double diaphragm couplingNot only can transmit relatively large torque and realize the connection of long wheelbase, but also can automatically correct the concentricity deviation between the shaft system between the motor and the fan, and realize simple and stable operation. It is the motor and the fan in the large torque and long shaft torque. The most satisfactory connection product under the circumstances.
Moreover, the installation process of the double diaphragm coupling is very simple. It only takes 1 day to complete the removal of the liquid lotus coupling and the installation of the double diaphragm coupling, which has very little interference to the equipment manufacturing process.Diaphragm coupling is a key component of mechanical transmission shafting. It is often used to connect two shafts or shafts and rotating parts to transmit torque and movement. It is used in metallurgical industry, fine chemicals, machinery equipment, vehicles and ships, and intelligent electronics. , Aircraft and other fields have been widely used.Diaphragm couplings are usually divided into two categories: rigid couplings and flexible diaphragm couplings. Because rigid couplings have a very high standard for the concentricity of the two shafts, flexible diaphragm couplings are widely used.Rigid couplings are suitable for scenarios where the relative displacement of the center lines of the two shafts is very small. This type of diaphragm coupling has the advantages of simple structure, small size, and low cost.
FlexibilityDouble diaphragm couplingIt has the following main features:
XNUMX. The strength of the elastic element is relatively high. Compared with other diaphragm couplings that can transmit the same torque, it is not only smaller in size, but also compact in structure.
XNUMX. The performance is very stable and the service life is longer.
XNUMX. The manufacturing process is relatively complicated and the cost is relatively high.
Fourth, the common metal material elastic elements are diaphragms, bellows, connecting rods, etc.
Double diaphragm couplings are mainly used in the following scenarios:
XNUMX. High-power and high-speed pumps and fans.
Second, the impact torque is relatively large, and the load changes drastically for mechanical equipment.
XNUMX. High-precision transmission mechanical equipment and data transmission system.
XNUMX. The scene of high temperature and high precision transmission standard.
Selection criteria for double diaphragm couplings:
XNUMX. According to the standard of the characteristics of mechanical equipment, it is necessary to consider the advantages of the transmission torque, rigidity, vibration, impact, corrosion resistance, transmission precision and so on.
XNUMX. The maximum torque that the diaphragm coupling can transmit is less than its design allowable range.The clarification of peak torque should fully consider the acceleration and deceleration torque and overload torque required for machine braking.
If the peak torque is not easy to determine due to insufficient data or difficult analysis during design, the torque measurement reference when selecting the diaphragm coupling can be used for details.That is, the measured torque does not exceed the allowable torque value.
