OLDHAM, We has improved the design
of the coupling and pump shaft with
new materials and manufacturing
procedures to reduce the risk of
failures. The key features of the new
lube oil pump coupling design are:
• Improved material ( 42CrMo4) with
increased hardness and toughness
• Pump shaft surface treatment
( Nitration hardening) to increase
hardness
• Passive lubrication of the coupling
through a new pump shaft design
( Figure 1)
• Oldham coupling, crankshaft
flange and pump shaft
interchangeable with the
original design.

The principal goals of this new design
are to decrease local contact
pressure and enhancement of
lubrication in order to reduce:
• Friction loads
• Working temperature
• Parts wear
• Fatigue damage
• Brittle failure
These goals have been reached with
the following actions:
• Passive lubrication of the contact
areas by directing a source of oil
from the pump to the coupling
using special hardware on the shaft
and control of tolerances that
permits a continuous flow of oil to
spill down onto the contact area
( Figure 3)
• Increasing the dimensions of the
coupling ( Figure 2)
• An improved profile to reduce
contact pressure
• Improving material and surface
treatment
Scope of work
The scope of supply for a typical
modification includes the following:
Engineering:
• Part number list
• Assembly drawings
Materials:
• Lube oil pump fully tested
• Oldham coupling
• Flange for compressor crankshaft
