A helical gear has a normal diametral pitch of 24, a normal pressure angle of 14 ½ o, 72 teeth, a face width of 0.25 in and helix angle of 45° The power comes from an electric motor, and the drive is to winch that will experience moderate shock. (a) If the gear transmits 0.50 HP at a speed of 3450 RPM, what would be the tangential force? (b) If the gear operates with a pinion having 16 teeth, what...
4. A gear is manufactured from SAE1045 hardened steel having pitch diameter D= 9.0 inches, having (13+12] 54 teeth, pressure angle 20°, which will operate 8 hours per day at 600 RPM with moderate shock 1oad. Design HP is 25 hp. a. Calculate the tooth load W (must show all steps with equations first) b. Calculate the minimum face width bw inches. Can use the handout on Spur Gear Design, along with accompanying data sheets.

A speed reducer has 20° full-depth teeth with a diametral pitch of 4 teeth/in, a face width of 3.25 inches, and with the pinion having 22 teeth and the gear having 60 teeth. The pinion is driven by a 40 HP motor rotating with a shaft speed of 1145 rpm. The pinion is designed to last for 5 years operating around the clock. The gears are manufactured using 4340 through-hardened grade 1 steel, both heat treated to 250 HB using...
Please help. Thx Part 2 (50 pts) A single-reduction spur gear system is as shown. The pinion "P" drives gear "G. Pinion"Pis driven at 1800 rpm with 1.5 hp Pinion "P" has a pitch diameter of 2 inches, and has 20 teeth. The gear "Ghas 120 teeth. All teeth have a pressure angle of 20, full-depth, hobbed profile, and a face width of 0.5 inches. All materials are steel. Determine: A) Minimum number of pinion teeth: Np,min This shows that...
designs QIII) A 15-tooth, precision-made spur pinion is to drive a 25-tooth gear. A pitch of 6 teeth/in has been selected with a 2.25 in face width. Also, the teeth are to be 25 full depth, with a ddendum of 1.35/ pa for a pinion speed of 1150 rpm, and 10 hp is to transmitted under steady load conditions. The material selected for both gears is a through-hardened steel of a hardness of 302 Bhn . Determined the actors of...
