Abstract
Apparatus for providing a variable angular velocity coupling between an input shaft (52, 78) and an output shaft (71, 138) includes a fixed frame (72, 74, 76); a first hearing (80) for mounting the input shaft for rotation relative to the fixed frame; a second bearing (140) for mounting the output shaft for rotation relative to the fixed frame; a pair of conjugate cams (48, 50; 82, 84) mounted to the fixed frame, concentric with the input shaft: a first cam follower (54, 60; 114, 118) pivotably supported (64, 66; 90, 92, 98, 100, 102, 104) by the input shaft for engaging a first of the cams; a second cam follower (56, 58; 116, 120) pivotably supported by the input shaft for engaging a second of the cams; a first link (68, 122) extended between the first and second cam followers to cause the followers to move in tandem in response to rotation of the input shaft relative to the cams: an radially extended output arm (70, 136) supported by the output shaft; and a second link (72, 74; 132, 134) extended between at least one of the cam followers and the output arm to rotate the output shaft in response to rotation of the input shaft, the cams having profiles (50; 148, 150, 152) to cause …
