The elastic diaphragm type coupling has the advantages of large torque and long service life, and the root of the tooth sleeve and the shaft sleeve have a large deformation area. In fact, the teeth are fixed on the shaft sleeve and the ring in the form of welding, so the phenomenon of stress concentration at the root can be changed. Because the shaft sleeve and the tooth sleeve are connected by the way of meshing each other evenly, and the elastic block is cushioned in the middle. All indices can correctly reflect the working capacity of the diaphragm elastic coupling's original attenuation coefficient vibration.

If the lubricating oil fails or the pressure cannot be built up, the moving surface completely loses the protection of the oil film, and the elastic diaphragm coupling directly contacts for dry friction. The alloy layer of the bearing shell melts when the temperature rises, the phenomenon of "holding tile" is generated when the machine is stopped, and more serious parts damage will be caused if the machine is not stopped in time. The radial deviation on each side of the outer circle of the coupling is measured by the Angle square and the feeler ruler, and the axial deviation between the end faces of the two halves of the coupling is measured by the feeler ruler.

When inspecting parts with complex shapes and large sizes, a table should be drawn before inspection, the shape size should be included in the table first, and then the positioning size should be included in the table, and then the measurement of a size in the order of the table and the measurement results should be written into the measured size column, so that the size will not be missed and the quality of the inspection can be ensured. Elastic diaphragm coupling clamping screw fixation: use the hexagon bolt tightening force to shrink the slit and grip the shaft tightly.

Piston rod installation to meet the requirements When the piston rod is interrupted for some reason, it is necessary to confirm that the work and the grinder are in normal condition before starting. The piston rod should be cleaned in advance of the grease, black dirt and dust at the processing wheel. The grinding wheel and grinding amount should be reasonably selected according to the material of the workpiece. It is strictly prohibited to grind the workpiece blank, and the elastic diaphragm coupling compensates for the relative position of the axis by the elastic deformation of the elastic element, and can also buffer and prevent the shock attack.
