The diaphragm itself is made of stainless steel plates, and each diaphragms group is stacked by several plates.Several diaphragms sets are staggered with two half couplings by bolts.The diaphragm coupling can compensate the relative displacement of the two axes caused by the elastic deformation of the diaphragm.It have 2 type: link type and integral type. It is a high-performance elastic coupling with sturdy metal elements. Its compact structure, high strength, long service life, and no rotation gap. There is no gear connection, so it is not affected by temperature and oil contamination. It has the characteristics of acid resistance, alkali resistance and corrosion resistance. It works easily even in high temperature, high speed, and corrosive environments. Because of its simple structure, light weight, small size, and easy to disassemble, diaphragm couplings with intermediate shaft type can be assembled and disassembled without moving the machine. The transmission efficiency is as high as 99.86%. Particularly suitable for high-speed and high-power transmission. Diaphragm couplings do not require lubrication or maintenance, which fundamentally eliminates vibration caused by gear surface wear ,and avoids a series of problem, such as imbalance caused by oil accumulation in the gear coupling.It is  can operate in harsh environmental conditions, such as any environment within 300  Celsius degrees, but also in corrosive environments such as acids, alkali, salt spray, etc.There are no gaps and noise when noise-free coupling parts are assembled, thus maintaining a constant initial dynamic balance accuracy. At the same time, it also has a high power-to-quality ratio, which is especially suitable for connecting high-power devices. The diaphragm coupling has a strong ability to compensate the misalignment of the two axes.The angular displacement is double of a gear coupling, the reaction force is small during radial displacement, and the flexibility is large, allowing certain axial, radial and angular displacement.The diaphragm coupling can accurately transmit the speed without slipping, and can be used for transmission of precision machinery.Diaphragm coupling can effectively reduce vibration and noise ,wear-free.In addition, the diaphragm coupling can also accurately transmit the speed without discrepancy, which is suitable for precision mechanical transmission. In addition to power units, diaphragm couplings are also widely used in various shafting transmission machinery, such as some high-power water pumps, chemical pumps, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery,and so on. For example, diaphragm couplings are also used in the transmission systems of helicopters, tracked vehicles, ships, etc. Diaphragm coupling: It is similar to the plum coupling, but the diaphragm coupling is more heavier，and the displacement adjustment ratio is larger, The diaphragm coupling is made of steel and aluminum a...

The elastic coupling is usually formed by wire cutting of a round metal rod. it is an integrally formed metal elastic body.Usually,it has three material:aluminum alloy, stainless steel and engineering plastics, suitable for various deviations and precise torque transmission.Elastic couplings contain pre-compressed  rubber elastic compounds, can provide extra strength and extend service life.Since the rubber part is a separate insert, it can be inserted after the shaft is aligned. So what are the fixing methods for elastic couplings? I will tell you in this article . Set screw fixation: Gap is 90 & ordm between two fixing screws.In the conventional fixing method, the front end of the screw is in contact with the shaft center, which may damage the shaft center or make dismantling difficult. Clamping screws fixing: With the tightening force of the hexagon  bolt, Slit shrink to clamping the shaft center. This method is easy to fix and disassemble, and will not cause damage to the shaft center. It is a common fixing method. Keyway type fixing: Suitable for high torque transmission. In order to prevent axial sliding, usually fixed with set screws and clamping screws. D-hole fixing: Generally, if the motor shaft is D-shaped ;if the positioning screws cannot be fixed, you can change the hole to the D-shaped hole of the motor shaft size ,then fix it with the positioning screws,  no need to worry about slipping. Expansion sleeve fixing: By tightening the four set screws on the end face of the coupling.Suitable for some high torque feed motors; the connection and fixing of servo motors; such as expansion sleeve diaphragm couplings；expansion sleeve plum couplings；expansion sleeve bellows couplings；expansion sleeve elastic couplings.     Above is some fixed method about elastic coupling,if you want to learn more ,please free to contact us ,we are glad to offer more product information and other service .

Shaft coupling refers to a device that connects two shafts or a shaft and a rotating part, and rotates together in the process of transmitting movement and power, and does not disengage under normal conditions. Sometimes shaft coupling is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. Let us learn more detailed information about shaft couplings. l What are the types of shaft coupling? l What are the features of shaft coupling? l What is the future of shaft coupling? What are the types of shaft coupling? Shaft couplings can be divided into two categories: rigid couplings and flexible couplings. Rigid couplings do not have the ability to buffer and the ability to compensate for the relative displacement of the two axes, which requires strict alignment of the two axes. However, rigid coupling has simple structure, low manufacturing cost, convenient assembly and disassembly and maintenance, and can ensure that the two axes have the neutrality of the transmission is greater. Rigid couplings can be used in flange couplings, sleeve couplings and clamp couplings. Flexible couplings can be further divided into flexible couplings without elastic elements and flexible couplings with elastic elements. The former type only has the ability to compensate the relative displacement of the two axes, but it cannot buffer and dampen vibrations, which is commonly used in slider couplings, gear couplings, universal couplings and chain couplings. Because the latter type contains elastic elements, in addition to the ability to compensate for the relative displacement of the two axes, flexible couplings with elastic elements also has the ability of buffering and dampening. However, it is worse than the flexible coupling without elastic elements for the torque is limited by the strength of the flexible element. Flexible couplings with elastic elements commonly are the part of elastic sleeve pin couplings, elastic pin couplings, plum-shaped couplings, tire couplings, serpentine spring couplings and reed couplings. What are the features of shaft coupling? The functions of shaft couplings can be described as follows: Shaft couplings have the ability of buffering, dampening, and improving the dynamic performance of the shaft system. Shaft coupling refers to a device that connects two shafts or shafts and rotating parts, and rotates together in the process of transmitting movement and power, and does not disengage under normal conditions. Sometimes shaft coupling is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. Shaft coupling is often composed of two halves, which are connected by a key or tight fit respectively, and fastened to the ends of the two shafts, and then the two halves are connected in some way. The shaft coupling can also compensate the deviation between the two shaf...
