  • What is the difference between Star Type and Plum-Shaped Elastic Coupling ?
    What is the difference between Star Type and Plum-Shaped Elastic Coupling ? Jun 10, 2013
    The Plum-Shaped Elastic Coupling has the characteristics of compensating the relative displacement of the two axes, damping, buffering, small radial size, simple structure, no lubrication, high bearing capacity, and easy maintenance.However, when the  replace elastic element , the two coupling halves need move in the axial direction. Star Type Elastic coupling with spider is made of polyurethane and rubber as elastic elements. It is suitable for connecting two coaxial transmission shafts. It can compensate the relative displacement of the two shafts, cushioning, damping and abrasion resistance. Star Type coupling with spider are sometimes mistaken for Plum-Shaped couplings. They have similar structures and almost similar shapes after installation.The difference is the shape of the elastic elements, which are star-shaped and plum-shaped respectively. However, the elastic performance of Star Type coupling with spider is lower than that of the plum coupling. because the elastomer of former is too thin , the elastic deformation is too small, so its performance must be lower than that of the plum coupling. Therefore, under the same model, Star Type coupling with spider can withstand more torque. Compared with the plum coupling, its inner hole and shape can make more smaller. Star Type coupling with spidersuitable for more precise occasions, such as precision instruments and precision machine tools.

  • Advantages and Applications of Diaphragm Couplings
    Advantages and Applications of Diaphragm Couplings Sep 04, 2021
    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...

  • Fixing Method of Elastic Coupling
    Fixing Method of Elastic Coupling Sep 10, 2021
    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 .
