A 24-tooth spur gear is to drive a 12-tooth spur gear. For both gears, the diametral pitch is 24 tooth/in.

A 24-tooth spur gear is to drive a 12-tooth spur gear. For both gears, the diametral pitch is 24 tooth/in. The gears are cut on the 20° full-depth involute system. Find and tabulate the addendum, dedendum, clearance, circular pitch, base pitch, tooth thickness at the pitch circle, pitch diameters, base circle radii, and contact ratio.

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...

A power train application requires the coupling of a spur gear to a transmission shaft operating at 3600RPM. The coupling must sustain a mean torque loading of 215Nm. There is a 20% torque ripple introduced to the drive line from the load. Select and design a coupling system using either a keyed coupling or an interference coupling such that the section of the transmission shaft at that location is minimized. Assume that the gear is located at the midpoint of...

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...
