Shaanxi JZM type diaphragm coupling

The JZM type diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected to the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rod type and Whole pieces of different shapes.

JZM typeDiaphragm couplingRelying on the elastic deformation of the diaphragm to compensate the relative displacement of the connected two shafts, without lubrication, the structure is compact, the service life is long, there is no rotation gap, and it is not affected by temperature and oil. It has the characteristics of acid resistance, alkali resistance, and _ High-temperature, high-speed, and corrosive medium shafting transmissions are widely used in shafting transmissions of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, High-speed power transmission systems of printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and naval vessels are commonly used in high-speed transmission shafts after being dynamically balanced.

The JZM diaphragm coupling device has the characteristics of large carrying capacity, light weight, small structure size, high transmission efficiency and transmission accuracy, convenient assembly and disassembly, and has no relative sliding, no lubrication, long service life, no noise, acid resistance, etc. It can be used in the working environment of high temperature, low temperature and oil, water and corrosive medium.Suitable for medium, high speed and large torque shaft transmission.As well as the shaft transmission with little change in load of various mechanical devices, it has strong versatility.

The correct method of installing bolts:

Insert the bolt from the outside of the small hole in the flange, and then pass it into the diaphragm hole (pay attention to the direction of the diaphragm, the diaphragm is composed of many single sheets, rivets and rivet washers, the rivet washers should be in contact with the buffer sleeve, otherwise It will affect the service life of the rivet set), and then insert the buffer sleeve, elastic washer, and tighten the nut from the outside of the large hole of the flange, so that the bolt does not rotate, because the bolt and the flange match section The surface is a very important part of the torque transmission, and the integrity of the surface directly affects the performance.

The gap between the bolt fitting section and the flange hole fitting section is generally based on the bolt diameter of 0.20mm～0.30mm. This fitting section plays a very important role in transmitting torque. If the gap exceeds the standard, replace it.

The diameter gap between the inner hole of the buffer sleeve and the diaphragm rivet and the bolt is 0.5mm～0.7mm, which plays the role of pressing and positioning the diaphragm.

If the bolts are installed in the direction, it is easy to cause the bolts to deviate, and the diaphragm will be twisted and deformed.

Therefore, pay attention to the direction of the bolt when installing the bolt. Do not install the bolt direction at will, otherwise it will cause the diaphragm to twist, and long-term operation will damage the surface of the diaphragm and the bolt mating section, and the small hole of the half shaft.
