What are the three advantages and characteristics of diaphragm coupling

Diaphragm couplings rely on metal diaphragms to convey torque and absorb deformation caused by errors. There is no relative movement between parts, no conflict, no wear, and therefore no need for smooth, in line with the development goal of oiling free process equipment. Tooth coupling is a rigid movable coupling, it depends on the relative slip between the tooth surface to compensate for the error of the two axes, so the tooth coupling to smooth, and smooth conditions are the main decision of the work of the tooth coupling. Unique is in high speed operation appears to be convex, such as under the action of centrifugal force, oil separation, leakage, and smooth oil selection, often because of the smooth design is connected to the mechanical bearing smooth oil, rather than bearing strength of the appropriate gear smooth oil. Therefore, the smooth problem of high-speed gear couplings is particularly prominent. On the other hand, the wear caused by the relative slip of tooth surface will lead to a series of problems such as sludge and inequality. Therefore, although the gear coupling used to be the choice of high speed and high power, but with the emergence and development of diaphragm coupling, the gear coupling gradually faded out.

Diaphragm coupling

Diaphragm coupling selection of metal diaphragm as an elastic element, high strength, convey load strength, and all the products do not exist non-metallic parts, no aging problem, long service life, and practical in the use of acid environment. This is not comparable to a metal elastic coupling.

Diaphragm coupling has three advantages:

First, technical support is hurried and sufficient. The selection of coupling can achieve the best match with the unit and achieve the best application effect. Choose products from Chinese manufacturers, in the process of unit design, the two sides may talk directly, and fully negotiate on functional parameters, structure size and so on. Moreover, this kind of communication is direct and useful, which can save time and increase design efficiency.

Second, the after-sales service response is rapid, unique is the supply cycle of spare parts greatly reduced. Chinese suppliers have a short manufacturing supply cycle, and may be able to respond to changes in demand sensitively, in case of emergency demand can respond quickly. In recent years, the service consciousness of the specialized manufacturers is obviously strengthened, and the service strength and service quality are constantly elevated.

Three, product value advantage obviously, unique is the value of spare parts is quite low. Under normal conditions, the value of domestic diaphragm coupling is only a fraction of the imported value. For the host manufacturer, may wish to reduce the cost of the set, for the end user, may wish to quickly obtain technical support and spare parts supply with a fairly low value in the subsequent operation.

Diaphragm coupling selection of high strength austenitic stainless steel diaphragm, may wish to receive larger deformation in the torsion at the same time, so as to compensate for the error of two axes. The non-metallic elastic coupling is restricted by the low strength and easy aging of the non-metallic elastic elements, which not only has a short life, but also has a small compensation strength. The gear coupling is restricted by the relative slip speed of the tooth surface and smooth conditions (with material introduction, the relative slip speed of the tooth surface should not be more than 0.12m /s), and the angular compensation strength is very small. Therefore, the non-metallic elastic coupling and tooth coupling installation alignment requirements are higher. Once the license line is exceeded in error, rapid failure of the coupling can be formed.
