Coupling diaphragm

 
● The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements.

, Without lubrication, compact structure, high strength, long service life, no rotation gap, not affected by temperature and oil pollution, acid and alkali resistance

, Anti-corrosion characteristics, suitable for high temperature, high speed, and corrosive medium shafting transmission, widely used in the shafting of various mechanical devices

Transmission, 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), high-speed power transmission system of ships, after being dynamically balanced, applied to high-speed

High-speed transmission shafting has become more common.
●The diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected with the two halves of the coupling with bolts, and each group of diaphragms is formed by stacking several pieces.

, Diaphragm is divided into connecting rod type and whole piece type of different shapes.
● JZMJ type diaphragm coupling for heavy machinery has high mechanical strength, large carrying capacity, light weight, small structure size, transmission efficiency and transmission

High precision, good reliability, easy assembly and disassembly, no relative sliding, no lubrication, long service life, no noise, acid and alkali resistance, anticorrosion

Corrosion and other characteristics, can be used in high temperature, low temperature, oil, water and corrosive media working environment.Suitable for medium, high speed and large torque shaft transmission

.As well as the shaft transmission of various mechanical devices with little change in load, it is extremely versatile.

● Use and maintenance

　　1. Before installation, the end faces of the two shafts should be cleaned, and the diaphragm coupling should be checked for the coordination of the key grooves on the end faces;

　　2. After the diaphragm coupling is installed, run a shift normally. All screws must be checked. If they are found to be loose, they must be tightened. Repeat this procedure.

Several classes to ensure that it will not loosen;

　　3. In order to prevent the fretting wear of the diaphragm during high-speed operation, resulting in microcracks and damage to the bolt holes of the diaphragm, paint between the diaphragms

Solid lubricants such as molybdenum disulfide or anti-friction coating treatment on the surface of the diaphragm; high-speed diaphragm coupling

　　4. Long-term overload use and operation accidents should be avoided;

　　5. During work and operation, check whether the diaphragm coupling is abnormal, and repair it if any abnormality occurs;
　 6. Appropriate protective measures must be taken at various sites where personal and equipment accidents may be caused by the operating diaphragm coupling.

Elastic diaphragm coupling
From the perspective of the industry as a whole, three issues need to be studied for technological transformation: First, how does the total scale of technological transformation fit the market demand of the "Eleventh Five-Year Plan"

What are the benefits of input and output? The second is the mode of technological transformation, the relocation of the old factory, or the mechanism, system, and technical equipment.

There is a new starting point; the third is the product goal of technological transformation, is it to manufacture middle and low-end products, or to develop high-end products? ———Functional components

The development is seriously lagging behind, and the surveyed companies have responded strongly. Zhou Dadi emphasized that a mature oil pricing mechanism requires a good spot market foundation.

It is necessary to establish a standardized spot market order, but also to have sufficient domestic supply capacity.
For joint ventures of state-owned enterprises, the policy should regulate the purchase price of steel diaphragm couplings. This stage is mainly to improve the degree of generalization and automation.

Research and develop mechanical equipment such as laser measurement, computer program control and TV sensing, using global positioning system, satellite information system and computer geographic information

Information system, etc.Utilize the scientific and technological resources already possessed by Chinese universities and research institutes to make full use of the scientific and technological resources already possessed by Chinese universities and research institutes

Resources to support the independent technological innovation of enterprises.
At present, many companies around the world have reduced their production in the third quarter. For example, Germany’s ThyssenKrupp Group reduced its output by 20 tons, and Nippon Steel reduced its output.

30 tons, the British-Dutch joint venture Corus reduced its output by 17 tons per month. The special diaphragm coupling for the servo can also be used to make automobile cover parts with cement plastic.

Mold.Sometimes a technological leap is an inevitable choice.
Servo motor supporting diaphragm coupling, the entry of powerful companies from home and abroad, has accelerated the development of the domestic construction machinery industry, and has also made industrial

The competition in the engineering machinery market is more fierce and cruel. The largest amount of heat treatment process materials is quenching agent.
