Power Engineering
employs state of the art analytical software to evaluate the bending
and fatigue life of spur gears under any conditions
identified in AGMA Standard 2001/2101. OEM manufacturing and quality
control practices can be appraised, audited and/or specified to
ensure Clients receive suitable, long lasting, spur gears.

Gears |
PE employs
state of the art analytical software to evaluate the bending and
fatigue life of helical gears under any conditions identified in
AGMA Standard 2001/2101. OEM manufacturing and quality control practices
can be appraised, audited and/or specified to ensure Clients receive
suitable, long lasting, helical gears.

| Epicyclic
Gearboxes |
PE has particular expertise in troubleshooting
and evaluating the performance of single and multiple stage epicyclic
gearboxes. Our systems capabilities, which encompass gear design,
tribology and lubrication,
vibration &
alignment measurements,
and metallurgy allow us to formulate comprehensive specifications
and/or system modifications to ensure high reliability and availability
of our Clients' epicyclic gearboxes. A recent project resulted in
extending the life of a set of underdesigned large gearboxes from
3.5 years to >10 years (exact number unknown since there have
been no failures since the implementation of our modifications).

Distress Macropitting |
PE has the
forensic experience to properly and accurately diagnose macropitting.
Diagnosis can be supplemented with analytical evaluation. Where
possible, PE provides recommendations on how to improve system parameters
to prolong life and reduce macropitting risk.

Distress Spalling / Contact Fatigue / Hertzian Stress |
PE has the
forensic experience to properly and accurately diagnose gear contact
fatigue problems. Diagnosis can be supplemented with analytical
evaluation. Where possible, PE provides recommendations on how to
improve system parameters to prolong life and reduce risk of fatigue
failures.

Distress Micropitting / White Staining / Gray Staining |
PE has the
forensic experience to properly and accurately diagnose micropitting.
Diagnosis can be supplemented with analytical evaluation. Where
possible, PE provides recommendations on how to improve system parameters
to prolong life and reduce micropitting risk. PE team members are
actively involved in AGMA committees tasked with investigating and
researching the basic science driving the phenomenon of micropitting.

Failure Analysis and Diagnostics |
PE has vast
experience in the analysis and forensic diagnosis of failed gears.
Analytical methods employed include state of the art, AGMA sanctioned,
gear rating computer programs and finite element modeling software.
PE has full laboratory facilities, including SEM, EDX and high magnification
microscopy, as well as excellent digital photography capabilities.
Our team has over 80 man years of failure analysis experience, encompassing
the entire range of tribological specialities, such that system
problems can be identified and solved in a comprehensive manner.

Metallurgy |
| PE has full laboratory
facilities and expertise necessary to comprehensively evaluate the
suitability of gear materials for service. Capabilities include SEM,
EDX, optical microscopy, micro and macro hardness testing, case and
temper evaluation, etc. Evaluation extends to type and suitability
of heat treatment, specified and achieved microstructure, and case
hardness process where applicable. |
