How to make the service life of the coupling longer

The service life of the diaphragm coupling is generally about one year: How to maintain the diaphragm coupling:

  1. Before installation, clean the end faces of the two shafts and check the fit of the key grooves on the end faces;

　2. After the diaphragm coupling is installed, all screws must be checked for normal operation in one shift. If they are found to be loose, they must be tightened. Repeat this for several shifts to ensure that they will not be loosened;

　3. In order to prevent the fretting of the diaphragm during high-speed operation, causing microcracks and damage to the bolt holes of the diaphragm, solid lubricants such as molybdenum disulfide can be applied between the diaphragms or the surface of the diaphragm can be coated with anti-friction Layer processing

　4. Lingsi diaphragm couplings should avoid long-term overloading and operation accidents;

　5. When the diaphragm coupling is in operation, check whether the diaphragm coupling is abnormal, and repair it if any abnormality occurs;

     An important way of coupling service life.The tooth width coefficient affects the tooth root bending strength and tooth surface contact strength of the tooth. The larger the tooth width coefficient, the greater the strength of these two items. The data of the tooth width affects the performance of the overlap. When the value is greater than this certain value, the value is The increase of φ has a smaller impact on the increase of the coincidence degree, and when the tooth width coefficient is less than a certain value range, the increase of its value has a greater impact on the increase of the coincidence degree. For the drum-shaped gear coupling of the arc drum curve , Tooth width is also a parameter that determines the bulge circle radius and backlash. The larger the tooth width, the larger the bulge circle radius and the greater the backlash required.The radius of curvature of the drum curve is proportional to the single-sided thinning of the internal tooth, that is, it is related to the meshing gap of the tooth. The lack of thinning may cause intervention, and the excessive thinning will weaken the strength of the tooth, and the backlash will be large. The smaller the concentrated load of a tooth, the better, and the curvature of the tooth surface is proportional to the circumference of the drum, so the radius of the drum is as large as possible.
