Question 1 A simple gear train of 30 and 50 teeth for pinion and gear wheel respectively, is used to drive an electric wheelchair at a velocity that is double the maximum velocity of slip. The pinion has an equal addendum as the gear wheel, a module of 3 mm, and a pressure angle of 14.5°. The wheelchair has a maximum velocity of 5 m/s when its pinion rotates at 800 r.p.m. Calculate: 1.1. The magnitude of the velocity of slip of gears in mesh. 1.2. The angular speed of the gear wheel in rad/s. 1.3. The maximum length of a path of the approach in mm. 1.4. The length of a path of a recess in mm. 1.5. The addendum of the gears in mm. 1.6. The contact ratio.
