Abstract

A device 8 that converts constant angular velocity to a sinusoidal output velocity as shown in Fig-ure 1. The device comprises three gears 10, 12, 14 of equal diameter, with input gear 10 shown at the start of a revolution. Gears 10 and 12 are kept in mesh by link 16 connected to shafts 13,20 with gears 12 and 14 kept in mesh by link 23 connected between center shafts 20,524. Shaft 26 and output shaft 24 are free to turn in a rigd frame. Gear 10 rotates on the frame on shaft 26 whale gear 14 rotates on the frme on shaft 24 Gear 12 rotates on center 20 which swings through an arc centered on shaft 20 During each revolution of input shaft 26, the output shaft 24 also makes one revolution with the angular veloclty ofthe output varying, as shown in Figure 2 The offset, as shown in Figure 2, 1s determined by the distance between shafts 18 and 26.

Generally, the device 8 could be used in any system where uncontrollled acceleration of a mechanical member creates unwanted torque spokes through a drive system More specafieally, the device could be used in a copier gaper registration system where at is necessary to carefully control accel...
