Determine the minimum number of teeth required on a pinion in order to avoid interference with. wheel to give a gear ratio of 3 to 1 b. An equal wheel The pressure angle is 20° and a standard addendum of 1 module for the wheel may be assumed 6. A pair of involute spur gears with 16° pressure angle and pitch of module 6 mm is in mesh. The number of teeth on pinion is 16 and its rotational speed is 240 rpm. When the gear ratio is 1.75, find the addenda on pinion and gear wheel b. the length of path of contact the maximum velocity of sliding of teeth on either side of the pitch point. Two gear wheels mesh externally and are to give a velocity ratio of 3 to 1. The teeth are of involute form; module 6 mm addendum one module, pressure angle = 20°. The pinion Sam rotates at 90 rpm. Determine: a. The number of teeth on the pinion to avoid interference on it and the corresponding number of teeth on the wheel, b. C. The length of path and arc of contact The number of pairs of teeth in contact, d. The maximum velocity of sliding.
