Henan JMIJ type connecting intermediate shaft type diaphragm coupling

JMIJ type intermediate shaft diaphragm coupling is a high-performance metal elastic element coupling, which is alternately connected by a sleeve in the middle, diaphragm sets on both sides, and half couplings through reamed bolts. The diaphragm set is made of multiple very thin stainless steel plates. The diaphragm set can be divided into two types: connecting rod type and integral type according to different structures.

JMIJ type with intermediate shaft typeDiaphragm couplingRelying on the elastic deformation of the diaphragms on both sides to compensate the relative displacement of the two connected shafts, the main features are no lubrication, compact structure, long service life, no rotation gap, not affected by temperature and oil, and it has the characteristics of acid and alkali resistance. , Suitable for shafting transmission in high temperature, high speed, and corrosive medium working conditions, and widely used for shafting transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery Petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission systems, after being dynamically balanced, are commonly used in high-speed transmission shaft systems.

The following points should be considered when choosing JMIJ type connecting intermediate shaft type diaphragm coupling:

Rated torque of diaphragm coupling (Nm): The start, stop, or forward and reverse rotation of the motor may impose a higher load on the diaphragm coupling; the larger torque of the motor is larger.Therefore, when designing and manufacturing the diaphragm coupling, it is necessary to satisfy that the larger load torque applied to the diaphragm coupling is below the rated torque.When a torque exceeding the allowable value is applied, the diaphragm coupling may be deformed and cause shortening of the service life or damage of the diaphragm coupling.If you need to perform forward and reverse frequently, please select; the rated torque should be 3 times the rated torque of the motor.

The peak torque (Nm) of the diaphragm coupling will be designed within the rated value.The static torsional stiffness (Nm/rad) refers to the torsional stiffness of the diaphragm coupling.Moment of inertia (Kgm2) refers to the moment of inertia of the diaphragm coupling.The higher speed (r/min) should meet the higher speed of operation when selecting the diaphragm coupling under ldquo; higher speed rdquo;.Radial deviation (mm) refers to the allowable value of the parallel deviation of the two connected shafts.The angular deviation refers to the allowable value of the angular deviation of the two connecting shafts.Axial deviation (mm) refers to the allowable value of the axial movement of the two coupling shafts.
