An external gear has a module of 4, 52 teeth in the gear, 28teeth in the pinion, a pressure angle of 20°, pinion rotationalspeed of 1500 rpm, face width of 20 mm, and gear and pinionmaterial having modulus of elasticity of 206 GPa and Poisson’sratio of 0.3. The Hertzian contact pressure is 0.980 GPa. Thelubricant used has an absolute viscosity of 0.3 Pa-s and pressureviscosity coefficient of 2.2 x 10-8 m2/N. Theroot-mean-square surface roughness for both the pinion and gear is0.1 µm. Determine the following:
- Transmitted power
- Minimum film thickness
- The film parameter
