Later maintenance of diaphragm coupling

 The diaphragm coupling also needs maintenance after installation. In the diaphragm couplingTwo dial indicators are set on the end face and outer circle of the shaft. When the shaft is turned by the turning, check the total runout of the diaphragm coupling including the end runout and radial runout values, and determine the straightness and coaxiality of the coupling and the shaft. Degree status.Different speeds and different types of couplings have different requirements for runout. After the coupling is installed on the shaft, it is necessary to make the deviation of the full runout of the coupling within the tolerance range required by the planning. This is a diaphragm coupling. One of the primary skill requirements for shaft equipment.After using for a period of time, each maintenance needs to check whether the beating value is still within the range.

The quality problem of the diaphragm coupling becomes the main reason:There are many reasons why the total runout value of the diaphragm coupling does not meet the requirements, and the main reason may be the fault of the processing composition.Regarding the field equipment, the diaphragm coupling and the shaft are out of axis due to improper key equipment.The correct equipment of the key should make the two peripheral surfaces of the key closely fit the wall of the keyway. Generally, use the coloring method to check the equipment. If the cooperation is not good, you can use a file or a spatula to correct it to meet the requirements.There is generally a free space on the top of the key, which is about 0.1-0.2mm.High-speed rotating machinery requires high coaxiality between the coupling and the shaft. A single key connection cannot obtain a high coaxiality, and a double key connection or a spline connection can improve the coaxiality of the two.

The value of diaphragm coupling:Diaphragm coupling is the most common type of coupling. When choosing a coupling, many people will choose a diaphragm coupling. The structure of the diaphragm coupling is simple, the number of parts is small, and the radial specifications are compared. It is small and does not need to be smooth, and the elastic element has high bearing capacity under pressure.When we replace the wearing parts of the diaphragm coupling, we need to move the half of the coupling axially, otherwise it will cause replacement failure, and the orientation will constitute an offset. Although the diaphragm coupling is a small object, it has a great function.

Good quality diaphragm couplings have higher reliability:This kind of diaphragm coupling has a certain degree of compensation for the relative deviation of the two shafts. Many diaphragm couplings have a very good application effect. The sales of diaphragm couplings in the market are very good. We are all about diaphragm couplings. It is dependent. The existing diaphragm couplings all use the processing procedures of CNC lathes and CNC machining centers. The products are precise in workmanship, high in precision, and more reliable in use.
