Assumptions Used Each flex plane of coupling acts like an angular spring: Moment = Ka*Angle Euler-Bernoullie Beam model neglecting shear Neglect all dynamic effects

Comments Dynamic effects not considered Motor and pump assumed symmetric. If not, then zero-shear at coupling does not hold. Angle seems more sensitive to deviation from symmetric. For the combination hard coupling, soft bearing, offset created less force than angle (both thin and thick shaft) Angle creates more bearing angle deviation than offset in most cases Offset tends to hit the inboard bearing. Angle tends to hit both bearings. (force magnitude) * Soft or hard coupling makes much less difference when both shaft is thin and beairngs soft.

Thick/hard/hard/angle (Same as slide 16) except increase pump between bearing distance from 30 to 35”. We’d think that is more flexible configuration that decreases stresses. However Max brg force increases from 4546N to 7435N

Same thing offset: 7157

Thick/hard/hard/angle (same as slide 16) Thick/hard/hard/angle (same as slide 16). Except DECREASE POB brg stiffness, significant INCREASE in max stress!

Same change for offset – not much effect
