Definitions

  • a vibratory road-roller has an improved vibrator shaft mounting along the operation of the machine with high inertia-forces. This is effected by mounting the vibrator shaft bearings in annular plates permitting axial movement of the shaft without radial movement.
  • the invention relates to a vibratory road-roller capable of producing variable inertia-forces and having an out-ofbalance shaft supported at each end in the interior of the roller body.
  • the object of the invention therefore is firstly to permit the production of low frequency inertia-forces of an order of magnitude greater than those at present obtainable, while taking this problem of mounting the out-of-balance shaft into account, and secondly to provide a construction which can enable operations to be carried out using a small inertia-force at high frequency.
  • a vibratory road-roller capable of producing variable inertia-forces, and having an out-of-balance shaft supported at each end in the interior of the roller body in a corresponding support comprising a pair of bearings disposed side by side in a common supporting housing which is suspended in an annular plate secured by its outer edge to the roller body, each of the plates being rigid in the radial direction but permitting slight play in the movement of the supporting housing in the axial direction.
  • the division of the supports into two bearings disposed side by said enables their individual bearing capacities to be utilized for producing inertia-forces in excess of the present-day standardized order of magnitude, without thereby encountering insoluble lubrication problems.
  • the bearings are roller bearings.
  • each annular plate can be formed from a number of disc-shaped laminations rather than as a single component.
  • the various laminations can be advantageously combined to form an annular element of fan-shaped cross-section.
  • the out-of-halance shaft is powered at different frequencies preferably by means of a reversing drive or a reversing gear.
  • the out-of-balance shaft can thus be changed over from anti-clockwise to clockwise movement by means of a simple switching operation.
  • the vibration roller By providing rotatably mounted imbalance masses on the out-of-balance shaft in the vicinity of stops, the vibration roller can be made to operate at high frequency and with reduced inertia-force during anti-clockwise movement and at low frequency and with a very high inertia-force during clockwise movement.
  • FIG. 1 shows a longitudinal section through a vibratory roller having bearing supports and an out-of-balance arrangement in accordance with the invention
  • FIG. 2 shows a section on line A-A through the outof-balance shaft for anti-clockwise movement and high frequency in the out-of-balance shaft;
  • FIG. 3 shows the same section through the out-ofbalance shaft for clockwise movement and low frequency
  • FIG. 4 is a plan view of an annular plate according to the invention.
  • FIG. 5 is a plan view of another annular plate according to the invention.
  • FIG. 6 is a sectional view taken along the line 6 6 of FIG. 5;
  • FIG. 7 is a sectional view similar to FIG. 6 but showing a plurality of plates arranged in the manner of lamellae.
  • the numeral 1 indicates the roller body and 2 the out- Of-balance shaft.
  • the out-of-balance shaft 2 is mounted at both ends in bearing supports which each comprise two cylindrical roller bearings, 3, 4 and 5, 6 respectively, disposed side by side.
  • bearing supports which each comprise two cylindrical roller bearings, 3, 4 and 5, 6 respectively, disposed side by side.
  • supporting housings 7, 8 which are suspended in annular plates 9, 10; the supporting housings 7, 8 are secured to the inner edges ⁇ 9, 10 of these plates and the outer edges 9, 10 0f the plates are secured, by means of ring inserts 18, 19 to the end-walls 20, 21 of the roller body 1.
  • the ring inserts 18, 19 also serve to secure the journal-covers 22, 23 of the roller body 1.
  • FIGS. 4 and 5 respectively, show annular plates 25 and 26 each having respective cutout portions 25a and 26a for reducing the rigidity of each plate in its axial direction.
  • FIG. 7 is a sectional view similar to FIG. 6 except that a plurality of plates 26 are shown which may be secured together through apertures 26b for producing a flexible lamellae of annular plates.
  • a vibration roller capable of producing ⁇ variable inertia forces, comprising a roller body, an axial out-ofbalance shaft mounted at opposite ends within said roller body, eccentric mass elements secured to said shaft within said body, bearing means for mounting each said opposite end, each said bearing means comprising a double bearing unit, each having a pair of bearings therein, each of said unit pairs being adjacent one another and each pair being lprovided in a common supporting housing, a thin annular plate member surrounding each said housing and being disposed substantially midway between the opposite ends of said housing perpendicularly to saidaxial shaft, each said plate member being mounted at its inner annular edge to each said housing and at its outer annular edge to the inside of said roller body, each said plate being rigid in a radial direction and tiexible in its axial direction, thereby permitting a wobblng movement of said shaft opposite ends in relation to the bending of said shaft during its rotation with said eccentric mass elements thereon, whereby each said pair of roller bearings are capable of adapting themselves to the inclined positions of said
  • Vibration roller according to claim 1 in which the annular plate consists of a multiplicity of annular plates arranged in the manner of lamellae.
  • Vibration roller according to claim 2, in which the lamellae of the annular plates have a fan-shaped cross section.
