Definitions
- the invention relates to a roller vibrator according to the preamble of patent claim 1.
- RoUen vibrators of the type concerned here are devices in which, in an interior that is rotationally symmetrical with respect to a device axis, excited by a pressure fluid, a rotor body that is approximately rotationally symmetrical with respect to its axis of rotation and has a smaller diameter than the interior of the device, with its axis of rotation parallel to the device axis rotates by rolling on the outer wall of the interior, its axis of rotation or axis of gravity describing a circle around the axis of the device, whose diameter multiplied by the rotor weight gives the working moment of the device.
- RoUen vibrators Nibrators with rollers as rotating bodies, so-called RoUen vibrators, generate higher forces with a lower pressure fluid requirement than the also usual ball vibrators, which contain a rotating ball as a rotor. RoUen vibrators have prevailed over bullet vibrators when higher efficiency is required.
- a rotor that is rotationally symmetrical and essentially cylindrical
- this is to be understood to mean a rotor which, in contrast to the pure ball vibrator, is cylindrical at least in its basic form.
- Devices with rotors that deviate from the ideal shape of a cylinder surface should also count to the invention. So such rotors from one or the other other reasons, for example, have circumferential grooves in their lateral surface, they can also be slightly spherical or, for example, be provided with raised running surfaces.
- the rotors usually have a really cylindrical surface, since a rotor with a changing diameter, which rests continuously on a correspondingly designed tread, no longer has a pure rolling behavior on the tread, since friction necessarily occurs.
- a continuous contact of the rotor with its running surface may be necessary for fluidic reasons.
- a roller-shaped rotor in the sense of this description does not necessarily have to have an elongated shape, but rather can also be disc-shaped with a diameter that is substantially larger than the length of its cylinder axis.
- the rotor also does not have to be a solid body, but rather can also be designed as a cylindrical ring.
- a roller vibrator in its basic design is described in US-A-3,365,964.
- the Nibrator shown there has a cylindrical interior and a cylindrical ring as a rotor.
- the housing cover is screwed against the housing jacket with a screw.
- a spacer around the screw prevents the rotor from getting caught.
- Pressure fluid is supplied only at one point on the inner surface of the housing, in one direction with a strongly tangential component. This direction determines the direction of rotation of the rotor.
- a fluid outlet opening is arranged in the direction of rotation after about 270 ° and also leaves the rotor space again in a strongly tangential direction.
- Mufflers for direct air outlet are often attached to the exhaust air outlet openings if the exhaust air is not to be diverted via connected hoses.
- Such commercial mufflers which can be screwed into a standard connection thread, consist for example of plastic or sintered metal.
- RoUen vibrators with axial air outlet are prone to failure, because, for example, screwed-on silencers break after a certain operating time.
- the invention has for its object to make a roller vibrator with several compressed air injection points distributed over the Umfeng more reliable.
- An additional task under a preferred Embodiment consists in also improving the wear behavior of a roller vibrator.
- the exhaust air discharge via the end walls or end cover of the device is also retained for a roller vibrator with a circumferential compressed air supply duct and a plurality of compressed air supply nozzles distributed over the circumference.
- circumferential ring channels are provided for collecting the exhaust air in the housing, to which the exhaust air from the grooves in the end faces is fed radially outwards and not to a central point radially inwards, as in the known device.
- An exhaust ring duct is therefore provided in the area of each housing end, the width of which at least partially overlaps the end of the race extends beyond so that it can communicate in this area with the radial channels in the end faces of the housing cover.
- the ring channels are expediently expanded at least at one point outwards into the housing jacket, for example by a screwing. These corresponding extensions of the ring channels are then connected to one another by an axially parallel transverse bore in the housing jacket, from which the exhaust air outlet opening then extends radially outwards.
- material areas are available in the corners outside the circular rotor space, into which the ring channels can be expanded. Such expansions are expedient so that the axially parallel transverse bore does not touch the circumferential compressed air supply duct.
- Continuous radial grooves in the end faces of the housing covers do not necessarily have to be provided for the discharge of the exhaust air on the end faces of the rotor space. Depending on the desired flow conditions, it may make sense to provide exhaust air openings in the end faces only along their circumference. These exhaust air openings are then temporarily covered by the rotor. Such openings in the inside of the end cover are expediently continued as angled channels which open into the circumference of the end cover. The associated ring channel is then arranged in such a way that it surrounds the outer circumference, for example as a groove in the internal thread of the housing shell, when the end cover is screwed in or otherwise mounted.
- the ring channels can either be incorporated into the inner surface of the housing shell, but also into the outer surface of the race. Appropriately, you will then work the circumferential compressed air supply channel in the middle accordingly in the housing jacket or the race.
- the connection of the ring channels to one another can also take place in this embodiment, as described further above, by extensions and axial transverse bores.
- the housing jacket and a housing end wall can be designed as an integral component without any problems by providing a detachable housing cover only at one end of the rotor space.
- This design can also be extended to the race by making it closed on one side like a pot.
- the entire component can be made of wear-resistant material.
- the housing cover can then be covered with a corresponding washer made of the wear-resistant material.
- the roller vibrator described not only offers a considerably reduced susceptibility to faults, in particular with regard to screwed-on silencers and lines, it also enables more wear-resistant interior equipment, which leads to longer service lives, and the wearing parts can also be easily replaced.

- Fig. 4 shows a partial axial section through the roller vibrator
- Fig. 1 wherein the rotor is visible in plan view and a housing cover is omitted;
- Fig. 5 is a view of the housing cover of FIG. 4, seen against the
- FIG. 7 shows a radial section through the race of the housing according to FIG. 6 along the section plane A1-B1 in FIG. 6;
- Fig. 9 is a perspective view of a race with the front
- the roller vibrator shown there has a housing with a housing jacket 2, which is provided on one side with a mounting surface 4. This is flange-shaped and has bores 6 for fastening screws (not shown).
- the housing jacket has an essentially cylindrical interior around its axis 8. This interior can be closed on the end face by threaded housing covers 10, only one of which is shown in FIG. 4.
- the cover 10 has engagement holes 12 for a screwing tool.
- a cylindrical ring-shaped race 14 is arranged in the interior of the housing, the housing covers 10 being screwed to the end faces thereof.
- the diameter of the rotor 20 is smaller than the inner diameter of the race 14.
- 2 and 4 2 coaxial, circumferential grooves are incorporated into the inner surface of the housing shell, of which the middle is a compressed air supply duct 24, while the two outer grooves are ring ducts 26 which belong to an exhaust duct arrangement.
- the compressed air supply channel 24 is connected to a compressed air inlet opening 28 (FIG. 1).
- the race 14 completely covers the compressed air supply duct 24.
- Two diametrically opposed compressed air outlet nozzles 30 are now incorporated into the race 14 and open into the rotor space 18 with a strongly tangential directional component.
- the blown compressed air must also be discharged again in order to ensure a pressure drop that keeps the rotor 20 moving.
- radial grooves 32 are machined into the inner end faces 16 of the housing cover 10. Since the rotor 20 never simultaneously covers the entire end faces 16 of the housing cover 10, the air always has the opportunity to enter the radial grooves 32, which communicate with the annular channels 26 at their radially outer ends.
- the ring channels 26 are therefore arranged so that their axial width extends at least partially beyond the race 14.
- the ring channels 26 are now in turn connected in a manner to be described below with an exhaust air outlet opening 34 which extends outward from the housing shell 2, in a plane which is perpendicular to the axis 8 of the housing shell and in one direction perpendicular to the mounting surface 4.
- the exhaust air outlet opening 34 also lies on the side of the housing facing away from the mounting surface 4 and also runs parallel to the compressed air inlet opening 28.
- these are provided with extensions 36 even in one of the upper corners of the housing shell 2, which can be worked into the housing shell 2 as arc-shaped indentations from the bottom of the ring channels 26.
- FIG. 3 As far as Figure 1 is concerned, the extensions 36 are not in the cutting plane EF, but recognizable in front and behind. The not entirely correct presentation was only for the purpose of illustration.
- the extensions 36 are now interconnected by a transverse bore 38.
- the open end 40 of this transverse bore is usually closed, but can also be used as an exhaust air outlet in special cases.
- the exhaust air outlet opening 34 is arranged as already described above. It is placed so that its inner end communicates with the transverse bore 38.
- FIG. 6 shows another embodiment of a roller vibrator in axial section.
- ring ducts 42 which are also arranged on both sides of the compressed air supply duct 24 essentially at the front ends of the rotor chamber 18, but are incorporated into the housing shell 2 such that they are located completely behind the race, which here designated 44.
- the race 44 has a number of openings 46 which connect the rotor space 18 to the ring channels 42. See also Fig. 7.
- the exhaust air is therefore not guided radially outwards by grooves in the housing covers, but rather directly from the front areas of the inner circumferential surface of the raceway into the ring channels surrounding it.
- This embodiment has the additional considerable advantage that, in particular, replaceable wear disks 48 can be arranged on the inner end faces of the housing cover 10.
- This also offers Embodiment the simple way to provide the one end of the housing shell 2 with an integrated housing end wall 50, so that only one housing cover 10 is necessary at the opposite end.
- the housing end wall 50 can also be provided with a wear washer 48 on its inner end face.
- the openings 46 in the race 44 can also be formed as bulges 62 in the race 44 on the edge, as shown in FIG. 9.
- a variant of the embodiment according to FIG. 4 can also consist in that the housing covers 10 have angular channels 66 in their outer circumferential area instead of the grooves in their end faces, as shown in FIG. 10.
- the annular grooves 26 are then to be arranged such that they can communicate with these angular channels in the peripheral region of the housing cover 10.
