Definitions

  • the invention relates to a rotary drum according to the preamble of claim 1.
  • a rotary drum according to the preamble of claim 1 is known from DE-C 866 895.
  • the ring gear and the running surface of the race ring have approximately the same outside diameter, the ring gear being arranged in an axial extension on the end face of the race ring.
  • the invention has for its object to design a rotary drum according to the preamble of claim 1 so that there is a substantial structural simplification, in particular a small volume in the axial direction.
  • the rotary drum according to the invention is illustrated in the drawing in the form of a tube mill 1.
  • this tube mill 1 can be largely constructed and constructed in a manner known per se. It has a rotating drum jacket 2 and - in the illustrated embodiment - at one end, namely the inlet end, a grist inlet 4 leading into a hollow spigot 3 and at the other end (outlet end) another hollow spigot 5, from which sufficiently ground material (arrow 6) from the Mill emerges.
  • a first race 7 is fastened coaxially to it in the region of the inlet end, whereby this first race 7 can be supported on conventional bearing elements, i. H. either on rollers or - as indicated in Fig. 1 - on hydrostatic or hydrodynamic plain bearing shoes 8.
  • a second race 9 is fastened coaxially, in a manner similar to the first race 7 itself known bearing elements, in particular on hydrostatic or hydrodynamic plain bearing shoes 10 is rotatably supported.
  • a ring gear 11 is arranged in a rotationally fixed manner, which - as will be explained in more detail below - is fastened directly to the second race 9 and thus forms a structural unit.
  • This ring gear 11 is in mesh with at least one drive pinion 12 (see FIG. 3, right half), which is part of a rotary drum drive 13 to be explained.
  • the second race 9 is provided at its two axial ends with a radially extending ring flange 9a and 9b, which - according to FIG. 2 - both protrude radially outwards.
  • the race 9 is screwed to an end flange 2a of the rotating drum casing 2 (as indicated by a dash-dotted line), so that the second race 9 represents an immediate axial extension of the rotating drum casing 2, but has a greater material thickness than the drum casing 2 (see Fig. 2).
  • the ring gear 11 On the second ring flange 9b of this race 9, the ring gear 11 is firmly screwed on (see dash-dot center line 14 of the screws), the outer diameter of which is kept somewhat larger than that of the race ring 9.
  • the ring gear 11 expediently has a T-shaped cross section, whose radially inwardly extending web 11 simultaneously forms a type of fastening flange and serves as a counter flange to the race flange 9b, while the teeth 11b are provided on the outer peripheral side of the T-shaped flange.
  • the ring gear 11 is thus fixed axially from the outside and yet is easy to install and replace on the outer end of the second race 9 and thus on the axially outer end of the rotating drum shell 2. Because of this arrangement, the ring gear 11 can expediently be designed in the form of an undivided (one-piece) ring which is distinguished by a low overall height. At the same time, the axial end faces of this ring gear 11 and in particular of its T-flange 11c c are preferably designed such that they can serve as axial guide surfaces 15, 15a.
  • two brackets 17, 17a are arranged in a fixed position (e.g. on the foundation 16), which can be designed in the manner of partial ring flanges and have sliding blocks 18, 18a on their mutually opposing sides wear from low-friction material, which are in sliding engagement with the axial guide surfaces 15, 15a of the ring gear 11.
  • the axial guide surfaces 15, 15a, together with the stationary sliding blocks 18, 18a form an axial guide for the assembly comprising the toothed ring 11 and the raceway 9.
  • this housing 19 is easily assembled and disassembled from a number of segment-like housing parts 19a, in such a way that the common housing 19 also protects the assembly of the second race 9 and ring gear 11 at the same time surrounds.
  • This common housing 19 or its housing parts 19a is or are provided with axial end walls 19b and 19c, on the radially inner edges of which suitable sealing elements 20 are held, which are connected to the outer circumferential side of the race 9 or a correspondingly provided on the ring gear 11, annular extension 21 are in frictional or sealing engagement.
  • the previously described design and arrangement of the housing 19 is a particularly favorable prerequisite for the gear rim 11 and its drive pinion 12, as well as the second race 9 and its bearing elements (slide bearing shoes 10), to be able to have common oil circulation lubrication, which can be of the customary design and therefore not is illustrated in more detail.
  • this common housing 19 are also the stationary sliding blocks 18, 18a of the axial guide described above for the assembly consisting of the race 9 and ring gear 11.
  • At least the rotary drum drive 13 is arranged to be adjustable with respect to the ring gear 11 and possibly also the bearing shoes 10 of the race 9 with the common housing 19 with respect to the assembly of the race 9 and ring gear 11, which is particularly useful for assembly, but also has a favorable effect for a later message possibility.
  • the indicated rotary drum drive 13 is designed and arranged in such a way that it has an output pinion, which at the same time forms the drive pinion 12 for the ring gear 11.
  • this also means that intermediate drive elements, such as. B. couplings, shafts, separate bearings, etc. can be omitted.
  • the torque of the transmission output pinion is thus transmitted directly to the ring gear 11 of the tube mill 1.
  • Fig. 3 the two main training options for the bearing elements arranged stationary below the tube mill 1 for the race 9 are also indicated. Thereafter, in the right half of FIG. 3, the race 9 is slidably and rotatably supported on several (preferably four in total) slide bearing shoes 10, while according to the left half of the drawing (FIG. 3) preferably two rollers 22 arranged symmetrically to the vertical longitudinal center plane 1 a of the tube mill 1 ensure rotatable support of the tube mill 1 via the race.
  • the partial cross section according to FIG. 4 shows a variant of the rotary drum drive 13 ', the main difference from the previous description is that the rotary drum drive 13' has two driven pinions, each of which simultaneously forms a drive pinion 12 ' for the ring gear 11. In an advantageous and space-saving manner, these two drive pinions 12 'can be arranged vertically one above the other. Otherwise, this embodiment variant according to FIG. 4 does not differ from the previously described embodiment.
  • each drive pinion 12 or 12 ' it should also be noted that it is preferred to do this self-adjusting with the associated output shaft of the rotary drum drive 13 or 13'. In this way, occasional minor axial displacements or displacements of the rotating drum shell 2 can be compensated for.
  • the race 9 can have a web-like flange 23 running approximately radially inwards on its inner circumferential side for the purpose of further stiffening the race.
  • this race 9 - instead of the flange connection with the flanges 2a and 9a - directly axially welded against the end face of the rotating drum jacket 2 facing it (as is known per se), but in any case on the other end face of the race 9 Ring flange (z. B. 9b) for the attachment of the ring gear 11 is available.
  • a further embodiment variant is indicated by dash-dotted lines in FIG. 1.
  • the assembly of the ring gear and the race does not necessarily have to be attached in the area of the outer circumferential side of the drum shell 2, but this structural unit can - as indicated by dash-dotted lines at 24 - also on the outer circumferential side of the one bearing or hollow journal, in the case of the hollow journal 5 shown Spout, be attached.
  • the training and arrangement can - with appropriate adaptation - be the same as in the previously described cases.
