No. 4266M Claims priority, application Great Britain, Jan. 28, 1964, 3,659/64 7 Claims. (CI. 74-54) This invention relates to operating mechanism for effecting reciprocating or oscillating movements and in particular to such mechanisms as are controlled positively in both directions by means of cams.
With mechanisms of the kind above mentioned, particularly for high speed operation, it is desirable to eliminate backlash and thereby impact due to taking up the clearance at the commencement of each cycle. The kinds of cams usually employed for this purpose are thread cams, grooved cams of face type or of drum type, and dual disc cams. Such cams are usually employed with roller-type followers, and whereas statically backlash may be taken up by making the cams an exact fit between two roller-type followers, for dynamic conditions an interference fit must be employed to eliminate backlash up to the full load rating of the mechanism.
If such interference fits make use only of the inherent elasticity of the components, the rate of variation of the pie-load is high for small increments of variation of fit. This can give rise to variations in the pre-load during operation of the mechanism, due to the effect of minor inaccuracies in manufacture of the cams or changing temperature conditions which cause differential expansion of the parts.
It is a main object of the present invention to overcome such difiiculties whilst retaining the advantages of preloaded followers.
According to the invention there is provided an operating mechanism which includes cam means engaged by a pair of follower rollers arranged to reduce backlash and impact due to the taking up of clearance at the commencement of a cycle, wherein one of the rollers is arranged for concentric rotation about the axis of a stud is rotatable about a second stud carried by the supporting member and is movable laterally of the axis of the sec- 0nd stud against the action of a spring exerting a preloading force along the direction of the axis of the second stud, the arrangement being such that if a force exerted against the second roller in a direction radial to the axis of the second stud exceeds the value of the preloading force the second roller is displaced from concentricity with the axis of the second stud until a state of equilibrium exists between the radial force and the axial force exerted by the spring.
In one embodiment of the invention the second roller comprises an annular cam-engaging member, a race coaxial with the second stud and mounted thereon for sliding movement axially thereof, said race having a conical bearing track located within the annular camengaging member, rolling elements housed in an annular track formed in the cam-engaging member for rolling engagement with the conical bearing track, and a preloaded spring operable to urge the conical bearing track of the race into engagement with the rolling elements. In another embodiment of the invention the second roller comprises an annular cam-engaging member, a pair of races co-axial with the second stud and mounted thereon, said races each having a conical bearing track located within said cam-engaging member and at least one of the races being slidable axially of the second stud and urged towards the other race by a pre-loaded spring, and rolling elements housed in an annular track formed in the cam-engaging member for rolling engagement with said conical bearing tracks.
The rolling elements may consist of rollers alternate ones of which are disposed with the axes of rotation thereof at right angles one to the other.
In order that the invention may be clearly understood some embodiments thereof will now be described, by way of example, with reference to the accompanying drawings, in which:
FIGURE 1 illustrates a part of a cam seaming mechanism having operating mechanism according to the invention applied thereto,
FIGURE 2 illustrates, partly in section, a part of the mechanism shown in FIGURE 1,
FIGURE 3 is a side elevation of a spring embodied in the mechanism of FIGURE 2,
FIGURE 4 is a plan of FIGURE 3,
FIGURE 5 diagrammatically illustrates an alternative embodiment of the operating mechanism,
FIGURE 6 is a sect-ion through a cam follower embodied in the mechanism of FIGURE 5,
FIGURE 7 is a section through a cam follower al ternative to that shown in FIGURE 6, and
FIGURES 8 to 15, in elevation and plan, illustrate alternative forms of spring which can be used in mechanism according to the invention.
FIGURE 16 is a fragmentary sectional view of the mechanism of FIGURE 1, wherein balls are illustrated as being the rolling elements.
In the drawings like references refer to like or similar parts.
Referring to FIGURES 1 to 4, a seaming roll I is supported by one arm 2 of a pair of arms secured to a stub shaft 3, FIGURE 1, for rocking movement about the axis of shaft 3 in a seaming roll support 4 rotatable about the axis of a chuck 5; the other arm 6 of the pair supports a pair of roller cam followers 7, 8 which cooperate respectively with cams 9, It) to cause the seaming roll to follow a path which conforms to the contour of the chuck, and to apply seaming pressure to the seaming roll.
The roller follower 7 is arranged for concentric rotation about the axis of a stud 11, FIGURE 2, carried by a supporting member which, in this embodiment of the invention, consists of a spindle 12. The second follower roller 8 is rotatable about a second stud 13 carried by the supporting member 12, and, as described below, is movable laterally of the axis of the second stud 13 against the action of springs 14 exerting a pro-loading force along the direction of the axis of the second stud 13, the arrangement being such that if a force exerted against the roller 8 in a direction radial to the axis of the second stud 13 exceeds the value of the preloading force the second roller 3 is displaced from concentricity with its axis until a state of equilibrium exists between the radial force and the axial force exerted by the springs 14.
The second roller 8 comprises an annular cam-engaging member 15 and a pair of races 16, 17 co-axial with the second stud 13 and mounted on the stud 13. The races 16, 17 respectively have conical bearing tracks 18,
19 located within the cam-engaging member 15 and the '3 ones of which are disposed with the axes of rotation thereof at right angles one to the other. The number of rollers 21 is an even number.
If desired instead of both races 16, 17 being slidable axially of the stud 13 one may be constrained against such movement in which event a-spring 14 will engagev only the one race which is free to slide axially of the stud 13.
As shown in FIGURES 2 to 4 the spring 14, or each spring 14, is a known form of slotted tube spring, see FIGURES 3 and 4, and sliding movement of the race or races is constrained by the force exerted by the spring or springs, thus the races are caused to close on the rolling elements 21.
It will be understood that if the spring, or springs, is deflected with the races 16, 17 in position a pre-load will be exerted upon the rolling elements 21 and that if a radial force .is exerted against'the member 15 which exceeds the value of the pre-load, then the member 15 will be forced off-centre to the stud 13 until equilibrium is maintained between the radial force and the axial force exerted by the spring 14.
The roller 8 can, therefore, be arranged so that its intended operating position, when assembled to the cam in co-operation with the non-yielding follower roller 7, is with the yieldable roller 8 displaced from concentricity with the stud 13 by an amount equal to one half of the total movement permissible by virtue of the proportions of the roller 8, and so that in this position the force exerted by the spring 14 is equal to the required pre-load on the cam surface.
It follows that variations of the cam surface due to inaccuracies or variation in relative position of the two follower rollers 7, 8 due to deflections or expansion will vary the degree of eccentricity between the yieldable follower roller 8 and its stud 13. It also follows that such variations will cause variations of the pre-load dependent upon the rate of the spring 14, and that such variations of the pre-load will be of minor character compared to those existing with two non-yieldable follower rollers as used prior to the invention, provided that such variations of eccentricity do not permit the. yieldable roller 8 to reach the point of concentricity or the point at which eccentric movement must be restrained to prevent rubbing contact of the roller 8 with non-rotating components.
FIGURE 5 illustrates diagrammatically an alternative embodiment of the invention in which the follower rollers 7, 8 co-oper-ate with opposite sides of the track 22 of a track cam. The rollers 7, 8 are mounted on studs which extend laterally from a supporting member 12 which is to be reciprocated by the cam. In this embodiment of the invention the roller 8 includes only one race 16 and this is slidable axially of its stud 13 and is urged towards the rolling elements 21 by the spring 14. FIGURE 7 illustrates an alternative form of the roller 8 shown in FIGURE 6.
FIGURES 8 to 15 illustrate known kinds of springs which can be used as alternatives to the spring shown in FIGURES 3 and 4. FIGURES 8 and 9 illustrate a helical compression spring 14a, FIGURES 10 and 11 a threepoint cup spring 14b, FIGURES 12 and 13 a Belleville spring 140, and FIGURES 14 and 15 a rubber ring 1411.
FIGURE 16 illustrates an alternative embodiment to that of FIGURE 2, wherein balls 22 are the rolling elements in engagement with the bearing tracks 18, 19 and 20.
