One method in which gear tooth interference can be avoided is to lengthen the pinion teeth and shorten the gear teeth. A 12 tooth pinion with a diametral pitch of 2 teeth/in and a pressure angle of (φ = 20°) is to be meshed with a 60 tooth gear at a center distance of 18 inches. Calculate the maximum addendum length of the gear teeth if there is to be no interference. Then calculate the addendum length of the pinion which will give a contact ratio of 1.6 if the maximum addendum length of the gear is used.

A 50-tooth spur gear is in mesh with a 27-tooth pinion. The gears have a diametral pitch of 5 teeth/in, and a pressure angle of φ = 25°. The gears transmit 80 HP at 4000 pinion rpm. Find the factors of safety against bending and surface failure. Assume that the teeth are full depth, Qv = 10, a through hardened to 360 HB steel gear, and a carburized and case hardened steel pinion. Assume a face width of 3.0 in,...

15.33 A spur gear reducer has an 18-tooth pinion driven 1500 rpm by an electric motor and a 36-tooth gear that drives a load involving “moderate shock.” A life of 106 pinion revolutions is required, and the transmitted load, Ft, is 100 lb (this figure includes a safety factor of 2). Conditions are such that Km = 1.8 and kt = 1. It is proposed that standard 20° full-depth gears be used, with both pinion and gear teeth being cut...
