WHAT GOES INTO THE DESIGN PROCESS OF A CUSTOM GEARBOX?
Some of the unique features that are reviewed in the Rj Link process:
Once the above features are reviewed with the customer, the Rj Link engineering team starts looking at specifications, ratings and cost. A decision has to be made if we are rating to AGMA, API or another standards. Some of the requirements that we look at for comparison are design & features, quality assurance and testing.
Comparing AGMA vs. API:
Some of the basic requirements that cover AGMA and API standards are the gear rating and service life. It’s the gear element construction and quality that matters to us. We get into dynamics, worry about vibration, bearings, noise any instrumentation, lube system, base plates, testing & QA documentation.
Other specifications in special gear units are the load capacity calculations, especially for spurs and helicals. We go back and do a comparison to an AGMA 2001-C95 standard.
Ratings: Looking at durability and strength.
Durability: API is a stringent rating system with no room for variation.
Strength: This is the bending stress number. This lets us know how much load can be put on the teeth before they flex and get into their elastic range.
Cost: There is approximately a 65% increase if you rate something to an API standard. The advantage is that you gain about 5x the design/theoretical service life.
