Field Testing
The speed reducer shall be field tested at rated speed and load to
demonstrate that reducer operation, lubrication, cooling, and
instrumentation meet contract requirements. The duration of the testing
shall be sufficient to develop verifiable gear contact patterns. Gear
contact patterns shall be inspected and shown to the Contracting Officer.
Gear contact patterns for helical gears shall be at least 70 percent of
face width. Spiral bevel gears shall have a central toe contact pattern
with contact of 50 percent of face width at full load. Gear contact
patterns shall be photographed and included as part of the field test
report. The report shall document all data collected for load and speed
measurement, lubrication, oil temperature and flow, ambient temperature,
cooling water temperature and flow, gear contact patterns, and any other
data required to show compliance with specifications. Should there be
insufficient water available to perform the test, the Contracting Officer
may delay the test for up to 9 months or waive the test.
