- A 20 Spur Pinion With 20 Teeth And A Module Of 2 5 Mm Transmits 120 W To A 36 Tooth Gear The Gears Are Of Good Quality 1 (55.73 KiB) Viewed 23 times
A 20° spur pinion with 20 teeth and a module of 2.5 mm transmits 120 W to a 36-tooth gear. The gears are of good quality with accurate mounting, and an 18 mm face width. The operating temperature of the gearbox is not expected to exceed 80°C, all loading is uniform, and a 50% reliability is required. Complete the following questions to determine the life expectancy of the gearbox based on the surface endurance strength and surface fatigue stress of the pinion.
