High-speed diaphragm coupling manufacturers will introduce to you:

1. Carefully check the straightness and coaxiality of the diaphragm coupling and the shaft. Usually, two dial indicators are set at the end face and the outer circle of the diaphragm coupling. When turning the shaft to roll, check the end face runout and radial runout data of the diaphragm coupling, which is used to judge the diaphragm The basis for the straightness and coaxiality of the disc coupling and the shaft.

2. The type of diaphragm coupling and the standard value of runout corresponding to the speed are different. After the installation of the diaphragm coupling on the machine and equipment on the shaft, it is necessary to carefully check whether the deviation value of the full run-out of the diaphragm coupling is within the plan Within the tolerance range of the standard, if it exceeds or falls below the tolerance of the planning standard, it must be corrected in time.

3. There are many reasons why the full runout value of the diaphragm coupling does not meet the requirements, but the product quality of the diaphragm coupling is the primary reason. The main factor causing the unqualified product quality of the diaphragm coupling is the manufacturer's production and processing. Production standards are not up to standard.

Summarize:

When the shaft center misalignment exceeds the allowable value during installation, the coupling may be deformed, resulting in damage or shortened service life. Tighten the screws after inserting the installation shaft, otherwise the coupling will be deformed. When tightening the screws, please use a torque wrench, and do not use screws other than accessories for installation. If there is abnormal sound during operation, please stop the operation immediately, and check the installation accuracy and screw looseness separately. It is recommended to apply adhesive on the outer surface of the screw after installation and debugging to increase the protection performance.
