Definitions

  • the invention relates to a roller mill according to the preamble of claim 1, as for example from DE 197 23 100 A1 is known.
  • the invention is therefore based on the object of making the drive of the roller mill cheaper. According to the invention, this object is solved by the features of claim 1.
  • the leading to the epicyclic gear drive train can be dimensioned correspondingly smaller, so that the drive components can be manufactured and procured correspondingly cheaper.
  • the mass in the drive train also reduces the moment of inertia. This in turn facilitates the control and regulation of the drive. Due to the grinding process, the drive elements are exposed to acceleration forces, so that here too the mass reduction has a positive effect on the design and fatigue strength of the bearings.
  • the planetary gear is preferably connected directly to the grinding roller and can be designed as a power-split transmission, in particular as a planetary gear.
  • the planetary gear then has, in particular a driven sun gear, which is expediently mounted tiltably.
  • the grinding roller on a Mahlrollenlagerung wherein the Mahlrollenlagerung and the epicyclic gearbox have a common oil chamber.
  • the grinding roller is rotatably supported according to a preferred embodiment of the invention on a pivot axis designed as a pivot lever.
  • the drive further comprises a drive shaft which extends in the form of a hollow axle pivot lever and is coupled to the planetary gear.
  • the drive also provides a motor, which is preferably arranged stationary. Likewise, a further stationary or mitschwenkendes with the pivot lever gear can be provided.
  • the epicyclic gear is attached according to a particular embodiment of the invention to the projecting into the grinding chamber end face of the pivot lever and has expediently an exchangeable wear protection.
  • the planetary gear is further connected to a separate moment support, which is arranged for example in the lateral guidance of a likewise provided Anpresssystems for adjusting the contact pressure of the grinding roller.
  • the drawing shows a partially sectioned side view of a roller mill.
  • the illustrated roller mill essentially comprises a rotatable grinding plate 1, at least one grinding roller 3 rotatably mounted on a pivoting lever 2, and a drive train associated with the grinding roller for driving the grinding roller with a fixed motor 4.
  • the pivoting lever is at one end outside a mill housing 7 in one Bearing 5 pivotally mounted about a pivot lever axis 6, while the grinding roller 3 is supported on the located in the mill housing end of the pivot lever.
  • a pressing system 8 in particular a hydropneumatic spring system, is provided in order to adjust the contact pressure of the grinding roller 3. It is also arranged outside of the mill housing 7 and is in operative contact with the pivot lever.
  • the grinding roller 3 is rotatably supported by a Mahlrollenlagerung 9 on the pivot lever 2.
  • the pivot lever 2 is further designed as a hollow shaft, so that a part of the drive train can be arranged in the form of a drive shaft 10 in the hollow shaft.
  • the drive shaft 10 is outside the mill housing with the stationary motor 4 in operative connection.
  • one or more transmissions (14) could be interposed.
  • the one or more transmissions can be both stationary and arranged on the pivot lever.
  • a clutch 12 is provided which compensates for the pivotal movement of the pivot lever.
  • the coupling (12) is preferably to be arranged in the pivot lever axis (6).
  • the coupling 12 is preferably a torsionally stiff compensation coupling, in particular a curved tooth coupling can be provided.
  • a mitschwenkendes transmission is also provided in the form of a planetary gear 15 which is fixed at the end of the pivot lever 2 in the field of grinding roller 3. It is designed as a power-split transmission and according to a preferred embodiment of the invention as a planetary gear.
  • the planetary gear is connected to the grinding roller and can be integrated, for example, in the grinding roller or attached to the frontal, located in the grinding chamber end of the pivot lever 2. As usual, it has a sun gear 15a, a plurality of planet gears 15b and a planet carrier 15c.
  • the sun gear 15a can be tiltably mounted and is driven via the drive shaft 10.
  • the planet carrier is rotatably connected to the grinding roller.
  • the planetary gear 15 is also protected by a preferably replaceable wear protection 15d.
  • a suitable torque support should be provided, which could be formed, for example, by lateral guides of the Anpresssystems 8.
  • the Mahlrollenlagerung 9 the bearing 5, the clutch 12 and possibly also the planetary gear 15 have a common oil chamber.
  • the teeth can be done with a smaller module and a smaller tooth width. As a result, the required space is minimized.
  • the planetary gear arranged in the region of the grinding roller has the advantage that the high torques are only generated where they are actually needed. This causes the moment and mass load of the before arranged drive train can be reduced accordingly. Due to this reduction of the torque, it is possible to compensate for the pivoting movement of the pivot lever with a toothed coupling.
  • the drive shaft 10, which is mounted in the formed as a hollow shaft pivoting lever is expediently not exposed to bending forces for reasons of strength and thus does not conform to the bending line of the pivot lever. Consequently, the connection between the drive shaft (10) and planetary gear (15) must have the ability to compensate for small angles. Due to the relatively low torque angle compensation can be done in the gear coupling.
