The diaphragm coupling should be maintained and replaced regularly

　　The service life of the diaphragm assembly determines the service life of the diaphragm coupling, which determines the cost of the diaphragm coupling and even the use of the diaphragm coupling, including related losses caused by shutdowns and failures (this is the main one) . .Diaphragm coupling, also known as laminated diaphragm coupling, steel flexible diaphragm coupling, with shock absorption and angular, axial and radial displacement compensation, can be used under severe conditions (such as temperature changes In large environments and acid-base environments, it allows high-speed operation without lubrication.

　　The precautions for the diaphragm coupling are as follows:

　　Diaphragm coupling products may be damaged on the edges. It is recommended to wear thick gloves when installing the diaphragm coupling.

　　Please install a protective cover and other equipment around the diaphragm coupling to ensure safety.

　　(3) When installing the diaphragm coupling, if the axial center deviation exceeds the allowable value, the diaphragm coupling may be deformed, which may damage the diaphragm coupling or shorten its service life.

　　4 The allowable axial deviation of the diaphragm coupling includes radial, angular and axial deviation.When installing, please make adjustments to ensure that the shaft center deviation is within the tolerance range of the corresponding product catalog.

　　_When various deviations of the diaphragm coupling occur at the same time, the corresponding allowable value should be reduced by half.

　　In order to prolong the service life of the diaphragm coupling, it is recommended to set the shaft deviation within 1/3 of the allowable value.

　　7 Insert the diaphragm coupling into the mounting shaft, and then tighten the screws, otherwise it will cause deformation of the diaphragm coupling tightening screws, please use a torque wrench, do not use screws other than accessories for installation.

　　8 If the diaphragm coupling has abnormal sound during operation, please stop the operation immediately and check the installation accuracy, screws, etc.After installation and debugging, apply adhesive to the outer surface of the screw.Improve protection performance.

　　The diaphragm coupling is a circular diaphragm coupling, which is connected with two sets of circular diaphragms, the diaphragm hole is connected with the dial, and the dial is connected with the main shaft and the driven shaft.The design is simple and important.In order to transfer activities, it has the function of compensating for the absolute deviation of the two shafts, and has high varying rigidity, suitable for low-power mastering systems and good machine transmission effects.

　　The vulnerable part of the diaphragm coupling is the diaphragm of the coupling.It must be checked regularly and replaced if necessary.

　　This kind of coupling is not only in short supply in quantity, but also in variety, quality and performance.The main reason is that the coupling is widely used and suitable for all industries.With the development of the equipment manufacturing industry, basic machinery parts and components have become a market with great potential.It can replace imports, save foreign exchange, or go abroad to earn foreign exchange.

　　According to the plan for the next few years, the total output of new products is 200000 units, each of which requires more than 10 sets of couplings and 200000 sets of 200 million units.There are other industries and exports, and the demand is quite large.According to production practice and current cost accounting, the selling price of this series of products is only 30% of the import price, and the interest rate is about 25%. (Calculated at an average unit price of 80 yuan per set, the output value of two million units can reach 4000 million yuan. Profits and taxes are as high as XNUMX million US dollars.) It is a high value-added product. It is not only conducive to participating in competition. , And there are products with development and promotion prospects, the potential market and economic benefits are very considerable.

　　For example, the transmission coupling products in the coupling, such as CNC machine tools as the mainstream equipment in the manufacturing industry, from the development trend of foreign countries, the new generation of CNC machine tools improve production efficiency and develop in the direction of super.High-speed, using new functional components (electric spindle, linear motor, etc.) to achieve ultra-high-speed processing.The required electric main shaft and linear motor are directly connected to the main shaft through the expansion joint sleeve, and the gear box and other mechanisms are omitted in the middle, realizing ultra-high speed.CNC machine tools require five to six sets of couplings, and fifty or sixty sets of couplings.This shows that this is a very huge market.

　　After years of process testing, improvement and innovation, domestic companies have advanced process technology, excellent processing and testing equipment and a complete quality assurance system, and product performance has reached an advanced level.At present, a large number of supporting hosts in the textile machinery, packaging machinery, printing machinery, mining machinery, machine tools, CNC machine tools, food machinery and other industries have replaced imports, and some products have been exported with the host and have achieved good economic benefits.

　　In summary, the above is about the content of the diaphragm coupling part, except for the content of the coupling, this is not an introduction for you.
