A gear pair is designed to provide a 3:1 reduction in speed. The design uses 12 DP gears, driving a 36-tooth gear with a 12-tooth pinion. What is the spacing between the gear centers?

4. What is the overall gear ratio for the following compound gear train? What is the output shaft speed and direction if the input shaft rotates clockwise at 1000 rpm? 8 teeth, Ø 5mm 16 teeth, Ø 10mm 24 teeth, Ø 15mm 32 teeth, Ø 20mm driver driven

Hello good Afternoon Sir, Permission, i have a question in my homework. The following bellow is question. Please advice. Thank you Regards,Irfan In planning the combined gears of the Ferguson planetary paradox as shown in the figure below.Sun gear hand input with angular speed (w2) = 0 rpm and hand input with angular speed (w.arm) = 400 rpm counterclockwise (ccw)Where is the number of teeth:Sun gear N2 = 100 (external gear)Sun gear N3 = 99 (external gear)Sun gear N4 = 101 (external gear)Planet gear N5 = 20 (external gear)Calculate the angular velocity, for each gear using the tabulation method. The data is in the image below

Pls explain to step by step and  i will rate your answer immediately. Thanks

A set of gears is cut with a 4'2-in/tooth circular pitch and a 17/½° pressure angle.* The pinion has 20 full-depth teeth. If the gear has 240 teeth, what maximum addendum may it have to avoid interference?

What is the solution for this?

Explain the following terms with reference to Spur gears: ①Pitch circle ② pressure angle ⑤ Backlash 6 Base Circle 3 circular pitch (4) Addendum
