How to measure the correct length of diaphragm coupling
Thread Content
There are four holes on each side of the diaphragm of the middle short axis, which is asymmetrical. How can the data measured with a vernier caliper be accurate? The data may be biased in different locations. Please advise.
Do you have any pictures? I think there are also pictures here, but they are all symmetrical.

It should be symmetrical. You can measure separately. Measure the intermediate shaft first. Measure the diaphragm again
It should be symmetrical, which factory are you from?
The four holes are the same central circle, and the coupling and diaphragm are the same diameter!
The picture is indeed not very good. I looked back and saw that I have an electronic version on my computer for you to refer to!
The right side is the diaphragm. The round hole on the diaphragm is the hole that can directly enter the middle tube so that the other side cannot
Diaphragm group measurement methods and drawings. Here are the reference and instructions for measurement drawings.
The diaphragm coupling half coupling disc will have two specifications of holes. The number of large and small holes is the same, but the center distance of the holes of these two specifications is the same. When two half couplings are connected, the small hole on one side faces the large hole on the other side.
