Chapter 9, Problem 9.10P

1. Given a gear of 32 teeth and 6 diametral pitch. Find the pitch diameter, outside diameter, tooth thickness, and the space width, given that the tooth proportions are standard 14 Brown and Sharpe. 2. A gearset has the following parameters: diametral pitch = 8, pressure angle = 20°, 19- tooth pinion meshed with 37-tooth gear. Find the gear ratio, circular pitch, base pitch, pitch diameters, center distance, addendum, dedendum, whole depth, clearance, and the outside diameters.

A 21-tooth spur pinion mates with a 28-tooth gear. The diametral pitch is 3 teeth/in and the pressure angle is 20°. Make a drawing of the gears showing one tooth on each gear. Find and tabulate the following results: the addéndum, dedendum, clearance, circular pitch, tooth thick- ness, and base-circle diameters; the lengths of the arc of approach, recess, and action; and the base pitch and contact ratio.

Solve this problem in spur gearsA 17-tooth pinion meshes with an 84-tooth gear. The full-depth involute gear teeth have 20° pressureangle and a diametral pitch of 32. Determine the base pitch and the contact ratio. Also,calculate theaddendum, dedendum, circular pitch, tooth thickness, and the base diameter for the pinion and gear. Ifthe center distance isincreased by 0.125 in., what are the new valuesfor thecontact ratio and thepressureangle with complete solution and write in hand writing thank you

A gear has 44 teeth of the 20°, full-depth, involute form and a diametral pitch of 12. Compute the following: a. Pitch diameter b. Circular pitch c. Equivalent module d. Nearest standard module e. Addendum f. Dedendum g. Clearance h. Whole depth i. Working depth j. Tooth thickness k. Outside diameter

A 20⁰ full depth involute gear, with 35 teeth and a diametral pitch of 8 is paired with a 12 tooth pinion. Find the gear ratio.

A pair of helical gears are machined with a hob. The hob has a 20 degree pressure angle and machines circular pitch of 0.55 inch/tooth on a spur gear. Two gears are machined, the pinion has 18 teeth and the gear has 36 teeth. The measured transverse diametral pitch on the pinion is 5 inch/tooth. The pinion transmits 10 hp at 1,000 rpm. Calculate the center distance of the gearset, in inches

A 20 straight-tooth bevel pinion having 14 teeth and a diametral pitch of 4 teeth/in drives a 30-tooth gear. The two shafts are at right angles and in the same plane. The illustration below shows a typical right-angle bevel gear set. Bevel gear pitch diameters are measured on the outside face along the back-cone, as shown in the figure. As shown in figure 13-35, the resultant force acts at the average radius of the gear/pinion. If the power transmitted by the pinion is 10 at 1,453 rpm, calculate the pinion tangent force in lbf. Cone distance A Face Pitch angle Pitch angle Back cone Uniform clearance Pitch diameter Da Back-cone radius, h

4. A pair of gear/pinion of 45 teeth and 15 teeth, respectively, with center distance of 40 cm, addendum at 0.725/p and dedendum at 1/p. The gear pressure angle is 20 degree. Compute for the diametral pitch in teeth per cm.
