Two 10-pitch gears are to be mounted 12 inches apart with velocity ratio of 5:1. Find the diameter and the number of teeth on both gears. Solution: A 20 degree spur gear with 18 teeth has adimentional pitch of 12. Determin: a) The pitch circle diameter. b) Diameter of base circle. c) Diameter of the addendum circle. d) Diameter of the dedendum circle. e) Circular pitch. For gear train shown in Figure Determin the output velocity and center distance of the gear train, where N1=24 N2= 36 and Pd=12 D3-2 in and Pd=10 N4=40 N5-16 and Pd=8 D6=6 in Solution: @ in 4 4 S out In the following figure, consider Input: Carrier (Link2) Output: Sun (link 1) Fixed Ring (Link 6) Gear 1: D= 1 inch, Pd=20 Gear 3: 45 teeth Gear 4: 20 teeth Gear 5: 30 teeth (keyed to the same shaft as gear 4) Gear 6: 150 teeth Determine the rotational speed and direction of all member when the input shaft rotates at 1000 rpm CCW.
