General couplings have a certain service life. In order to facilitate the installation of the diaphragm coupling It is best to put the two half couplings in a 120-150 incubator or oil tank for preheating, so that the inner hole size increases and it is easy to install.

After installation, ensure that the shaft head does not protrude from the end face of the half coupling . When the flange outer circle is less than 250mm, the runout value should not be greater than 0, 05mm; when the flange outer circle is greater than 250mm, the runout value should not Greater than 0, 08. The Drive Shaft performance limit temperature of the diaphragm coupling elastomer determines the operating temperature of the diaphragm coupling is generally -35 to +80 degrees. Use a wrench to tighten the nut. If so, tighten the nut with a wrench in time. Since elasticity has the function of buffering and damping, it is used more in situations with strong vibration. What are the precautions for the diaphragm coupling when working?

The general diaphragm coupling must pay attention to certain matters during operation.Couplings are mechanical parts that connect motors and equipment to rotate together to transmit torque. The life of a general diaphragm coupling is also the life of elasticity. Instructions for operators of diaphragm coupling Before starting the equipment, check whether the nut of the diaphragm coupling is loose or falling off. Aligning the diaphragm coupling Use a dial indicator to detect the runout of the flange end and outer circle of the two halves of the coupling.

Clean up the half coupling and clean the bruises with a fine file. Check the prime mover before installing the diaphragm coupling Whether the two shafts of the working machine are concentric and whether there are wrapping paper and scratches on the surfaces of the two shafts, whether there are debris in the inner holes of the two half couplings of the diaphragm coupling, whether there are bruises on the edges of the inner holes, and if so, the shafts should be removed. The life of an elastic body is usually 10 years.

Install the diaphragm coupling bolt Insert the bolt from the outside of the small hole in the flange, and pass it through the outside of the large hole in the other flange. If the installation is unsuitable or disassembly and replacement, without damaging the shaft and the half coupling, it is better to rotate freely after installation. Put on the buffer sleeve, elastic washer, and twist the nut. Because diaphragm couplings are one of the couplings, they are in use The service life is also subject to certain restrictions.
