Abstract:
A sector gear is formed as one of a pair of mirror image gears (12, 14). Each of the sector gears has an arcuate portion (16) having a series of teeth (18) on an outer periphery thereof, and a V-shaped base portion (20) having a first leg (22), a second leg (24) and an apex portion (26). The first leg (22) has an S-shaped configuration and connects with the arcuate portion (16) at a first end thereof. The second leg (24) has an inverted S-shape and connects with the arcuate portion (16) near an arcuate mid-length of the arcuate portion (16). The first leg (22) and second leg (24) merge smoothly with the apex portion (26). The apex portion (26) has an aperture (30) at a radial center of the arcuate portion (16). Each of the gears has an inner periphery (28) that enables complementary nesting of the pair of sector gears (12, 14).
