A simple gear train of 30 and 40 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 is pinion rotates at 800 r.p.m . Calculate: 1.1) The magnitude of the velocity of slip of gear 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 recess in mm. 1.5) The addendum of the gear in mm. 1.6) The constant ratio.
