Definitions
- the invention relates to a cellular wheel sluice with an inlet shaft, an outlet shaft and a housing with a cell wheel rotatably mounted in a housing bore by means of a shaft, which has a plurality of webs which extend essentially radially from the shaft to the periphery of the cell wheel and axially closing side plates of the cell wheel.
- the rotationally fixed connection between the cellular wheel and the shaft is made using a key.
- This structural design enables the shaft or cellular wheel to be replaced individually in the event of damage, or the shaft to be replaced by a modified component, for example in the event of a subsequent change in the shaft drive.
- a drive shaft can be used in a large number of different cellular wheels and can be manufactured in a correspondingly large number.
- a two-part shaft is also used in the rotary valve according to FR 1.183.967, which has a rotor that is axially closed on one side only.
- a shaft part is integrally connected to the cell wheel, which in turn is connected to a molded on the second shaft part, disc-shaped flange is screwed.
- Drive shaft have an enlarged diameter due to the reduction in strength in the area of the weld seams, which increases the weight of the rotor. Since the cellular wheel is extremely rigid against the protruding shaft ends, particularly high stresses occur in the transition area to the side windows when loaded.
- each side window is conical Hollow body is formed, the tapered ends of which lie opposite one another.
- the webs are only brought up to the outer surface of the cone and are therefore not directly connected to the axial end surfaces of the cellular wheel. In this way, the transition region between the shaft ends and the cellular wheel is made more elastic, obviously unintentionally.
- the cavities in the cones are rather used for flushing with compressed air.
- the utility model GM 74 17 697 shows a rotary valve in which the side windows are welded to the drive shaft with an internal ring seam. In the area of the weld seam, the corners of the webs are obviously recessed, so that the end faces of the webs are at a slight distance from the annular weld seam. Such a lock is fundamentally unsuitable for use in pressure delivery systems due to poor tightness.
- the present invention has for its object to provide a cellular wheel for use in high pressure locks, which has a particularly favorable distribution of mechanical stresses and is still relatively easy to manufacture.
- the object is achieved in that the side windows are arranged on annular projections of the shaft. That way relocated the connection point between the shaft and the side window in an area in which only slight stresses occur when the lock is operated under a high pressure difference, so that an inherently strength-reducing integral connection, in particular by means of welding, is also possible without problems.
- Fig. 1a shows a longitudinal section through a rotary valve according to the invention
- FIG. 1b shows a cross section through the lock according to Fig. 1a
- FIG. 2a shows a longitudinal section through a rotary valve according to a further embodiment of the invention
- Fig. 2b shows a cross section through the lock according to Fig. 2a
- FIG. 3a shows a longitudinal section of a further rotary valve according to the invention
- FIG. 3b shows a cross section through the lock according to FIG. 3a
- the cellular wheel sluice shown in Figure 1 a, b consists of a housing 1 with an inlet shaft 2 and an outlet shaft 3.
- a cell wheel 7 is rotatably mounted by means of a shaft 5 and roller bearings 6.
- the cellular wheel comprises a plurality of chambers 8 which are formed by webs 9 which extend radially from the shaft 5 to the circumference of the cellular wheel 7.
- the chambers 8 are axially closed on both sides via side windows 10. Seals 11 seal the housing bore 4 with respect to the roller bearings 6 arranged in side covers 12.
- the outlet shaft 3 can open into a pneumatic delivery line, not shown, in which there can be a gas pressure which is increased, for example, by 6 bar compared to the surroundings.
- the cellular wheel 7 is fitted with narrow gaps in the housing bore 4 in order to keep the escape of the conveying gas from the outlet shaft 3 to the inlet shaft 2 within permissible limits.
- the shaft 5 In the manufacture of the cellular wheel 7, the shaft 5, the side windows 10 and the webs 9 are prefabricated as separate components and are integrally connected to one another by welding.
- the shaft 5 has annular projections 13, on the outer circumference of which the correspondingly drilled out side windows 10 are placed and welded. The transition of the projections 13 to the rest of the body of the shaft 5 is rounded, so that no noteworthy notch stresses or welding stresses occur in this area.
- the webs 9 are provided in the region of the annular projections 13 with triangular recesses 14 which extend laterally from the shaft base 15 to above the annular one
- the introduction of the large-area partition plates 16 is necessary in any case in order to improve the emptying of the chambers 8 into the outlet shaft 3.
- the cellular wheel can be designed according to FIGS. 2a, b.
- the separating plates 16 are designed as conical shell segments, each of which along the recesses 14 a side window 10 and the mutually adjacent webs 9 are sealingly connected.
- the cellular wheel according to FIG. 2 corresponds to the previously described embodiment.
- the cellular wheel 7 can be manufactured in accordance with FIG. 3.
- two shaft segments 17, each provided with an annular projection 13 are prefabricated in one piece and connected to one another in a mirror-image arrangement via a tubular connecting piece 18 forming the shaft base 15 and the webs 9.
- the tubular connecting piece 18 is arranged coaxially to the shaft segments 17 and is pushed onto both ends of the correspondingly shaped pins 19 of the shaft segments 17 for centering.
- this rotary valve corresponds to the embodiment according to FIG. 1.
- cellular wheel 7 and housing bore 4 can have a shape that deviates from the cylindrical shape.
- the annular projections 13 can also be provided with a width that is variable over the diameter in order to influence the membrane-like deformation in a targeted manner.
- the shape of the recesses 14 is not limited to triangles, even if this design is particularly simple to manufacture. LIST OF REFERENCE NUMBERS
