Talk about the diaphragm coupling longevity secret

Products people want to make it use longer life, the use of diaphragm coupling is no exception, not the product itself is good quality long life, this is also related to the use of diaphragm coupling environment, so when customers buy coupling, to use in what environment also tell our sales staff, in case the sales staff tailors for you to create more appropriate products.

Diaphragm couplings are a little bit like bellows couplings, in fact they all transmit torque in a similar way, the diaphragm itself is very thin, so it bends easily when relative displacement load is applied, so it can withstand up to 1.5 degrees of deflection, and at the same time produce a lower bearing load in the servo system, diaphragm couplings are often used in the servo system, The diaphragm has good torque rigidity, but less than the bellows coupling, on the other hand, the diaphragm coupling is very delicate, if misused in use or not properly installed, it is very easy to damage, so the deviation within the normal operation of the coupling tolerance is very necessary.

Diaphragm coupling and rigid coupling also belong to the elastic coupling, whether need conditioning treatment depends on the coupling working condition. In order to design a diaphragm component with simple structure, reasonable force and long service life, the shape of the patch can be appropriately changed or the number of patch can be increased according to the needs. If the coupling use power is large, it is recommended to reduce the quality of diaphragm coupling. The service life of the diaphragm assembly determines the service life of the diaphragm coupling, and determines the cost of the coupling and the whole machine, including shutdown, joint loss caused by failure (this is the main). High temperature tempering refers to tempering between 500 and 650℃. Tempering can make the performance of steel, material has been greatly adjusted, its strength, plasticity and toughness are good, has a good comprehensive mechanical properties. Tempered soxite was obtained after tempering treatment. tempered sorbite is formed when martensite is tempered. This kind of tempered sorbite can be distinguished only by the size of 500~600 times under the optical mirror phase microscope. It is a composite structure where carbide (including cementing) spheroid particles are distributed in the ferritic matrix.

Although researchers have studied the diaphragm coupling, many research results or limited to theoretical research, not from the structure of a better solution, such as the domestic production of diaphragm coupling in terms of appearance quality or service life and other aspects compared with foreign products are _ gap, the introduced diaphragm coupling speed can reach more than 20000 RPM, The speed of domestic diaphragm coupling is difficult to exceed 10000 RPM; Or limited to a special structure to explore after fire high temperature tempering heat treatment method called tempering treatment. It is also a tempered structure of martensite, which is a mixture of ferrite and granular carbide. At this time, the ferrite has almost no carbon sudesaturation, and the carbide is stable carbide.
