Which of the coupling types listed is shown in the illustration? See illustration MO-0087.
• Compare how a rigid (solid) flange coupling is constructed versus a flexible or fluid-type coupling • Look for any signs of flexible elements (rubber, diaphragms, chambers) or fluid-filled housings in the illustration • Note how the shaft is directly bolted to the adjoining piece and whether there appears to be any space for oil, air, or hydraulic fluid
• Does the drawing show any chambers, housings, or spaces where fluid (oil) or air could be contained, or is it simply metal parts bolted together? • If a coupling is called "flexible," what physical features would you expect to see that allow misalignment or shock absorption, and do you see those here? • Count the main components: how many distinct pieces are there between the shaft and the driven member, and do any of them look like a pump, turbine, or flexible element?
• Verify whether there is any visible cavity or housing that could hold hydraulic fluid or air • Check if there are any rubber, spring, or diaphragm elements that would allow flexing between the two sides • Confirm whether the two sides appear to be rigidly bolted together as one solid unit with no intermediate flexible or fluid element
