Definitions

  • Vibrators are commonly used with materialshandling, such as to expedite the flow, settling, etc. of solids, semisolids and the like.
  • One of the best-known examples is the utilization of vibrators in concrete molds. In cases where the mold is of substantial size, it is necessary to use several vibrators or to provide several mounts so that a smaller number of vibrators may be moved from one mount to the other. The latter alternative has several advantages but presents a number grated with its mount and yet must be easily and quickly removable so as to be used with other mounts.
  • the typical rotary vibrator operates on theprinciplc of orbiting a weight about an axis to create a condition of unbalance which is used to impart vibrations to an object to which the vibrator is affixed.
  • the weight is of course eccentric to the axis of the means that confines the weight to follow an orbit.
  • the weight may be carried by a shaft, as in US. Pat. No. 3,036,658, and in others theweight may be a roller smaller in diameter than and confined .by a circular track, as in US. Pat. No. 3,3l8,l63.
  • Yet other forms of vibrators are known. In all these is this characteristic:
  • the casing or other means that carries the orbiting weight, rotor, etc. is subjected to migratory or precessive rotative movement in the direction of rotation of the orbiting member, from which it follows that the easing must be securely fastened to the object to be vibrated or it will vibrate itself loose from the object.
  • the casing can be welded to the object, but this prevents free and easy removal of the vibrator from one location to the other, and, since removal and relocation are desirable, the mount must be temporary but effective and must not require constant attention, must be relatively simple and inexpensive and must be substantially free from environmental problems; e.g., rust, corrosion, accumulation of the material being handled. etc.
  • the problem is solved by constructing the mount as a tubular member within which a substantially circular vibrator casing is initially loosely fitted.
  • the object to be vibrated may be provided with several tubular mounts sothat one vibrator may be easily and simply moved from one mount to the other.
  • the interior of the mount has one or more cam surfaces and the exterior'of the casing has one or more cooperating cam surfaces.
  • FIG. 1 is a plan view of an exemplary vibrator in its initial position as related to its mount.
  • FIG. 2 is an elevation of the same.
  • FIG. 3 is a section on the line 3-3 of FIG. I.
  • FIG. 4 is a section on the line 44 of FIG. 1.
  • FIG. .5 is an enlarged fragmentary view showing the action of the cam, ramp, inclined plane, etc. during operation of the vibrator.
  • the selected vibrator includes a casing or carrier structure 10 having an interior circular track 12 within which a rotor 14 is confined by the track and by a pair of side plates l6 retained by snap rings 18.
  • the track I has an annular groove 20 to which fluid under press uree.g., compressed air-is supplied by a tangential port 22 formed in such a way as to be connected to a pressurized inlet 24 which in turn is supplied by a fluid pressure source shown schematically at 26 (FIG. 1). It is only in the area of the external disposition of the inlet 24 that the vibrator shown herein differs from that in U.S. Pat. No.'3,3l8,l63. Further, whether the vibrator is driven by compressed air or otherwise is of little mo ment.
  • the side plates each have annular grooves 28 provided respectively with exhaust outlets 30.
  • An object to be vibrated e.g., a concrete mold or the likeis designated at 32, and to this is affixed one or more mounts typified by a mount or mounting structure 34.
  • the mount 34 is rigidly affixed to the object 32, as by welding at 36.
  • the mount includes a member 38 of tubular form or configuration, so shaped and dimensioned that the vibrator casing 10 fits intitially relatively loosely therein; i.e., sufficiently so that the'casing may be easily inserted in and withdrawn from the mount when the vibrator is idle and yet not so loosely as to permit the acor cloverleaf", particularly in the area of its interior Assuming further that the casing 10 fits within the tube 38-although the parts could obviously be reversed-,
  • the tube is non-circular.
  • the high and low areas are achieved because of the dift'erence in cross-wise or radial dimensions.
  • the basic center of the tube occurs at x (FIG. but the three parts of the tube are formed about three axes y, so that, as measured from the center or axis x, the radius or dimension a is greater than the dimension b, and areas in which the arcs merge provide the cam or ramp areas or surfaces 40.
  • the tube 38 is ovalized", and itis clear that fewer or more than three cams, ramps etc. could be provided, and, likewise the surfaces need not be arcuate.
  • the present description is based on a simple construction.
  • the exterior of the casing is complementarily formed; i.e., it has three cooperating cam or ramp surfaces 44, but here again, as said above, the number of cams is representative only.
  • the casing has two basic cross-wise or radial dimensions c and (1 wherein a is less than c, is less than a but is greater than b.
  • a rotary vibrator and mounting structure therefor wherein the vibrator has a casing, a rotor in said casing and means subjecting the rotor to a continuing driving force causing the rotor to orbit about an axis and resulting in a unidirectional migratory rotative movement of the casing about the orbit axis and the mounting structure and easing are interfitted with each other so that the structure carries the vibrator, characterized in that the casing and structure respectively have initially loosely interfitting portions, said rotor and easing being provided with cooperative cam surfaces arranged to engage and to continuously tighten as a result of the aforesaid migratoryrotative movement of the casingso long as the driving force to the rotor is continued.
  • tubular configuration of the mounting structure is non-circular so as to provide the interior with cross-wise dimensions of greater and lesser lengths and the exterior of the casing is also noncircular and has cross-wise dimensions of greater and lesser lengths, the greater dimension on the casing being less than that in the structure but greater than the lesser dimension in the structure.
  • the mounting structure is of tubular form having an interior surface including at least two circumferentially merging surface portions of different radial lengths whereby the area of the merger of the portion of greater length with that of the lesser length provides an interior cam, and the exterior of the casing is configured to initially fit loosely into the structure and has an exterior cam engaging and tightening with the interior cam upon the aforesaid migratory rotative movement of the casing.
  • a rotary vibrator having a casing, a rotor in said casing, means for continuously driving said rotor about an axis, mounting structurefor the easing and including a cam portion, a cam portion on the casing engageable with the structure cam portion and adapted to continuously tighten as a result of unidirectional migratory rotative movement of the casing ensuing from continuous driving of the rotor.
  • the structure is tubular and a portion thereof is of generally oval configuration and the casing initially loosely fits within the structure and has its exterior cam portion engageable with the cam provided by the decreasing radial dimension of the oval portion of the structure as the casing partakes of the aforesaid migratory rotative movement.
