Definitions

  • the invention relates to a roller mill with the features specified in the introductory part of claim 1.
  • a roller mill is, for example, in the exemplary embodiment according to FIG. 8 DE 3801728 C2 already described.
  • the grinding table is driven, which drives the grinding rollers via the grinding bed.
  • it is generally necessary to arrange a gear below the grinding plate.
  • these gearboxes require high investment costs, long procurement times and unsatisfactory availability.
  • a fixed motor In the DE 197 02 854 and the SU-A1-1 346 238 is proposed as an alternative embodiment, a fixed motor.
  • This cardan shaft must have an angular compensation in the joints and an axial balance in the intermediate shaft
  • the invention is therefore based on the object to improve the eingungs described roller mill to the effect that are minimized by the drive train of the grinding roller conditional vibrations of the system.
  • a clutch can be used which makes it possible to transmit the rotational motion homokinetic, so that the vibrations introduced by the drive train into the system are minimized.
  • the required compensation movement is minimized and consequently a cost-effective and maintenance-free compensation clutch can be used.
  • the stationary motor allows the use of commonly available standard motors, so that the components of the drive train can be procured at a lower cost.
  • the coupling is designed as a torsionally rigid compensation coupling, whereby a long life can be ensured.
  • This coupling can be formed for example by a toothed coupling, a multi-plate clutch or a propeller shaft. If a universal joint shaft is used, the intermediate shaft is to be arranged so that it is cut by the pivot lever axle or its extension and so the rotational movement can be transmitted homokinetically.
  • the pivot lever is designed as a hollow shaft, wherein a part of the drive train is arranged in the hollow shaft.
  • the drive comprises one or more gears, which are optionally stationary and / or arranged on the pivot lever and / or in the region of the grinding roller.
  • At least one transmission can be designed as a planetary gear, which is attached to the grinding roller.
  • the planetary gear may be a power-split transmission, in particular a planetary gear.
  • a contact pressure system for adjusting the contact pressure of the grinding roller can be provided that is in operative contact with the pivoting lever.
  • the pivot lever is formed so that it is passed through a mill housing and the grinding roller at the Mill housing located end of the pivot lever is mounted, while the other end is mounted in a bearing outside of the mill housing.
  • the grinding roller is mounted with a Mahlrollenlagerung on the pivot lever, the Mahlrollenlagerung, the bearing of the pivot lever and the coupling can have a common oil chamber.
  • the grinding roller rotates about a grinding roller axis, wherein the fixed motor is arranged with its motor shaft substantially in the extension of the Mahlrollenachse. But other arrangements come into consideration.
  • the drive axis of the stationary motor can also be arranged offset parallel to the Mahlrollenachse, the drive train is deflected by the motor to the grinding roller by 180 °.
  • Roller mill shown essentially consists of a rotatable grinding table 1, at least one rotatably mounted on a pivot lever 2 Mahlalter 3 and one of the grinding roller associated drive train for driving the grinding roller with a fixed motor 4.
  • the pivot lever is pivotally mounted in a bearing 5 about a pivot lever axis 6 ,
  • the pivoting lever 2 is further passed through a mill housing 7, wherein the grinding roller 3 is mounted on the located in the mill housing end of the pivot lever, while the other end is mounted in the bearing 5 outside of the mill housing.
  • a pressing system 8 in particular a hydropneumatic spring system, is provided in order to adjust the contact pressure of the grinding roller 3.
  • the pressure system 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 is arranged in the form of a drive shaft 10 in the hollow shaft.
  • the rotational movement of the drive shaft is transmitted via a scar 11 on the grinding roller 3.
  • the drive shaft 10 is operatively connected to the stationary motor 4, wherein one or more gears can be interposed.
  • the gear can be both stationary and arranged on the pivot lever.
  • a clutch 12 After a part of the drive train is formed stationary and another part, in particular arranged in the pivot lever 2 drive shaft 10 mitschwenkt with the pivot lever 2, a clutch 12 must be provided which compensates for the pivotal movement of the pivot lever.
  • the clutch 12 is arranged in the pivot lever axis (6) and transmits the rotational motion homokinetic.
  • the coupling 12 is preferably a torsionally stiff compensation coupling, in particular a curved tooth coupling can be provided.
  • the Mahlrollenlagerung 9 the bearing 5 and the clutch 12 via a common oil chamber 13th
  • the embodiment according to Fig. 2 differs from the first embodiment essentially only in that the drive train still a fixed gear 14 and a mitschwenkendes gear in the form of a planetary gear 15 are provided.
  • the planetary gear 15 is fixed at the end of the pivot lever in the region of the 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 15 has, as usual, a sun gear 15a, a plurality of planet wheels 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 pivot lever 2 is formed as a hollow shaft, so that a drive shaft 10 can be arranged for transmitting the rotary motion to the grinding roller 3 in the hollow shaft.
  • the drive train includes in this embodiment, a stationary drive train, which is formed in particular by the motor 4 'and a mitbewegten with the pivot lever 2 drive train, in addition to the arranged in the pivot lever 2 drive shaft 10 still another shaft 16, a first gear 17, in particular a gear transmission, and possibly a second transmission 18 includes.
  • a clutch 12 is provided, which is also arranged here in the pivot lever axis 6 and its extension.
  • the drive train is therefore, starting from the motor 4 'via the shaft 16, the first and second gear 17, 18 on the associated with the grinding roller 3 drive shaft (10) u m 180 ° deflected.
  • the special drive configuration also makes it possible to choose a clutch which ensures homokinetic transmission of the rotational movement, so that vibrations of the system caused by the drive train of the grinding roller are minimized.
