Analytical Expressions of the Efficiency of Standard and High Contact Ratio Involute Spur Gears

Figure 17

Percentage difference in the estimation of power losses with uniform and minimum elastic potential load distribution models: (a) standard spur gears; (b) high contact ratio spur gears.

(a) Energy loss, 𝑊_𝑠(𝑣=cte,  𝜇=cte) versus 𝑊_𝑠 (𝑣≠cte,  𝜇=cte): relative error

(b) Energy loss, 𝑊_𝑠(𝑣=cte,  𝜇=cte) versus 𝑊_𝑠 (𝑣≠cte,  𝜇=cte): relative error
