Abstract
A cam arrangement comprises a solid cam mounted on an input shaft for rotation and having a plurality of ribs formed on a circumferential surface thereof, the solid cam being formed to a non-circular configuration at an outer periphery of the ribs, the ribs including a linear portion and an inclined portion. A spider is mounted at an end of an output shaft which extends perpendicularly to the input shaft and is disposed for both rotation and reciprocation a plurality of cam followers are mounted on the spider and each is guided between adjacent pairs of the ribs. The spider is pressed resiliently against outer surfaces of the ribs.
Claims3
A cam arrangement comprising:
- a housing;
- an input shaft rotatably mounted on said housing;
- a solid cam having a central portion fixed to said input shaft and having a plurality of ribs formed on a circumferential surface thereof and spaced from each other, said solid cam being formed to a non-circular configuration at an outer periphery of said ribs, said ribs including a linear portion extending in a circumferential direction and an inclined portion inclined in a lateral direction with respect to said circumferential direction;
- an output shaft extending in perpendicular relationship to said input shaft and mounted for rotational movement and also for movement in opposite axial directions;
- a spider fixed to an end of said output shaft and maintained in contact with said outer periphery of said ribs of said solid cam;
- a plurality of cam followers mounted on said spider, each said cam follower being guided between an adjacent pair of said ribs;
- and
- means for resiliently pressing said spider into continuous contact with said outer periphery of said ribs.
