Abstract
An intermittently moving device having an input shaft which a cam is attached to, and an output shaft which has a cam follower to be engaged with the cam and bearings mounted on both side of the cam follower so as to prevent inward movement toward the cam follower. The output shaft is adjustable in axial direction by screwing of adjusting wheels in which the bearings of the output shaft are inserted. The outward end face of the bearings are held by step differences.
Claims3
An intermittently moving device comprising a case, an input shaft to which a cam is attached, an output shaft which crosses orthogonally with said input shaft and is provided with a cam follower to be engaged with said cam;
- said case has inner screw holes which are formed on a first pair of confronting walls of the case, an opening end of each of said holes is provided with circumferential notched grooves having an engaging surface, a second set of inner holes are formed on a second pair of confronting walls which are at right angles to said first pair of confronting walls;
- said output shaft has bearings mounted on both sides of said cam follower so as to prevent inward movement toward said cam follower and, is supported in said case by adjusting wheels;
- each of said adjusting wheels has a bearing hole provided with a step difference in order to insert said bearing thereinto and to hold the outward end face of said bearing with said step difference, and is screwed in said respective inner screw holes;
- and each of said adjusting wheels is held in place by a locking piece which is mounted on the outward end face of said adjusting wheel and engaged with said engaging surface of said notched grooves.
