JM Diaphragm Coupling

Structure of JM Diaphragm Coupling

JM diaphragm coupling, also known as elastic lamination coupling, or lamination flexible coupling, is one of the new types of couplings developed in recent years. Various misalignment errors of the system (radial error, axial error, angular displacement error, error caused by temperature rise change), JMI type basic diaphragm coupling with countersunk hole, mainly depends on the middle of the coupling The elastic metal diaphragm is used to transmit the torque between the two shafts, which has the advantages of shock absorption, no wear, and no maintenance. It is an ideal product to replace gear couplings and general couplings today. The standard implemented by our factory is (JB/T9147-1999).

The characteristics of JM diaphragm couplings are a bit like bellows couplings. In fact, the way the couplings transmit torque is similar. The diaphragm itself is thin so that it flexes easily when relative displacement loads arise, and thus can tolerate misalignments of up to 1.5 degrees, while producing low bearing loads in the servo system. Diaphragm couplings are often used in servo systems. The diaphragm has good torque rigidity, but it is slightly inferior to bellows couplings. On the other hand, diaphragm couplings are very delicate and can be easily damaged if misused in use or installed incorrectly. Therefore, the deviation is very within the acceptable range of the normal operation of the coupling. Choosing a suitable coupling is a key step in using the coupling well. It is necessary to consider what type of coupling to choose during the design stage.

JM diaphragm coupling is a kind of all-metal flexible coupling. It transmits the torque generated by the driving machine to the driven machine through the elastic element-diaphragm assembly, and compensates the axial and radial torque caused by manufacturing errors, installation errors, deformation after loading, and temperature changes between the two axes of the unit. and angular offset.

Maintenance-free rotating machinery (or devices) should be the highest purpose and realm of product designers.

It can be assembled and disassembled without interfering with the main and slave devices. Only two adapter flanges are designed, and the entire coupling can be assembled, disassembled or replaced within one or two hours when needed. This feature has special advantages in petrochemical process equipment.

Ability to operate under severe conditions Since the key part of the coupling - the flexible component - is made of stainless steel, it can not only resist the corrosion of acid, alkali and salt, but also maintain the original mechanical properties under the condition of 300 degrees Celsius. This feature is beyond the reach of other couplings (especially rubber couplings).
