<Jie Tan> coauthored <Development of Face Gear Technology for Industrial and Aerospace Power Transmission by Gregory F. Heath and others> with <Gregory F. Heath> and <Robert R. Filler>. Its2002 title page identifies Tan with The Boeing Company in Mesa, Arizona. The work investigated concentric <face gears> and <floating pinions> as a means of distributing transmitted <torque> between parallel paths.<Development of Face Gear Technology for Industrial and Aerospace Power Transmission by Gregory F. Heath and others>[Title page and Summary, printed p.iii]{ref}

The report is useful because its apparatus revealed that different load divisions in one <split-torque transmission> need not agree. While input-pinion mesh division was close to48/52, the idlers were reported near57/43. The authors related the idler imbalance to how <backlash> had been set using strain indications, and discussed the limitations of inferring the split from those indications alone.<Development of Face Gear Technology for Industrial and Aerospace Power Transmission by Gregory F. Heath and others>[Summary, printed p.iii; §VIII, torque-split method and results, printed pp.71–78]{ref}

In an illustrative100-unit load normalization, a57-unit path is14% above the intended50-unit equal share. A geometric <gear ratio> can remain correct despite that unequal internal loading. Tan's coauthored study therefore provides a concrete connection between transmission geometry, adjustment and experimentally inferred forces, rather than treating the desired speed ratio as a complete description of mechanical performance.
