Definitions

  • the invention relates to a roller mill with a rotatable grinding table and at least one rotatably mounted on a pivot lever Mahlertenerten grinding roller, which is in Abrolleingriff with the grinding table, wherein the pivot lever is pivotally mounted about a pivot lever axis.
  • the grinding table In roller mills in industrial applications, the grinding table is driven, which drives the grinding rollers via the grinding bed. In this case, it is generally necessary to arrange a gear below the grinding plate. For mills with high throughput rates, these gearboxes require high investment costs, long procurement times and unsatisfactory availability.
  • the invention is therefore the object of the drive of the roller mill to make cheaper, according to the invention this object is achieved by the features of claim 1.
  • the roller mill according to the invention essentially consists of a rotatable grinding plate of at least one rotatably mounted on a pivot lever grinding roller, which is in Abrolleingriff with the grinding table, wherein the pivot lever is pivotable about a pivot lever axis, and at least one communicating with the grinding roller drive train of a stationary motor and has a fixed gear.
  • the drive train further comprises a mitschwenkendes with the pivot lever and / or the grinding roller gearbox.
  • the two gears are preferably connected to one another via an angle-adjustable and / or axially adjustable shaft.
  • the mitschwenkenden gear is a planetary gear, in particular a power-split transmission, which can be formed for example by a planetary gear.
  • This mitschwenkende transmission can also be integrated into the grinding roller or attached to the grinding roller.
  • the pivot lever is mounted in a bearing, wherein the mitschwenkende transmission can be arranged before or after the camp in the work string.
  • the pivot lever can be formed as a hollow shaft, wherein a part of the drive train is arranged in the hollow shaft.
  • the drive train may further comprise a coupling which is arranged in the pivot lever axis or its extension and compensates for the pivoting movement of the pivot lever.
  • This coupling can be formed for example as a toothed coupling, in particular as a curved tooth coupling or as a propeller shaft.
  • Roller mill shown consists essentially 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 hydro-pneumatic spring system, provided 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 at least one stationary gear 14 and a mitschwenkendes with the pivot lever 2 gear 15 'are interposed.
  • a radially and axially adjustable shaft 16' for transmitting the rotational movement and to compensate for the pivotal movement of the pivot lever 2 is provided.
  • This shaft 16 ' may be formed, for example, as a propeller shaft.
  • mitschwenkende transmission 15 ' is arranged in the first embodiment in the region of the bearing 5 of the pivot lever 2, it is according to the second embodiment in Fig. 2 in the grinding chamber, ie laid in the mill housing 7.
  • the mitschwenkende transmission 15 according to Fig. 2 is arranged on located in the mill housing 7 front end of the pivot lever 2 and connected to the grinding roller 3.
  • the mitschwenkende transmission could also be integrated in the grinding roller.
  • the arrangement of the mitschwenkenden transmission in the field of grinding roller the high torques are generated exactly where they are needed.
  • the leading to the mitschwenkenden transmission 15 powertrain can be made according cheaper and easily procured. Reducing the masses in the powertrain also reduces the mass 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 shaft 16 can be provided in the region of the bearing 5, so that under certain circumstances can be dispensed with an axial adjustability of the shaft and the shaft (16) must ensure only one Winkelver combinkeit.
  • Fig. 2 could be provided instead of the angular and / or radialaxialver ausen shaft 16 and a clutch.
  • the coupling is also arranged in the pivot lever pivot axis 6.
  • the planetary gear as usual, 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 3.
  • the planetary gear 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.
  • a clutch 12 is further provided which compensates for the pivoting movement of the pivoting lever.
  • a coupling 12 is used which is arranged in the pivot lever pivot axis 6 and transmits the rotational movement homokinetic.
  • the coupling 12 is a torsionally stiff compensating coupling, in particular a curved tooth coupling can be provided.
  • the grinding roller bearing 9, the bearing 5 and the coupling 12 has a common oil space.
  • the drive train between the two transmissions can be realized due to the reduced torque there by standardized components.
  • the mitschwenkende transmission into the grinding chamber i. laid in the area of the grinding roller, a torque-reduced and mass-reduced drive train can be provided.
