Definitions

  • the present invention relates to a drive according to the preamble of claim 1.
  • Large, cylindrical rotary bodies are used, for example, in ball, rod or cement mills.
  • the material to be processed is poured into a cylindrical grinding drum, which is rotatable about a horizontal axis.
  • the grinding drum is supported on bearings and has a ring gear, which is generally formed at one end on the circumference and into which pinions of the grinding drum drive engage.
  • a pair of pinions engages horizontally laterally in the ring gear of the grinding drum, while the bearings are arranged below the longitudinal axis of the grinding drum.
  • the drive forms a unit together with the reduction gear.
  • This arrangement has the advantage that the drive and the gear can be easily moved into the ring gear and can also be easily removed or opened for maintenance work.
  • the large lateral space requirements and the large height of the necessary gear foundation have a disadvantageous effect.
  • the object of the present invention was to find a drive for such a rotary body, which requires less space on the side of the rotary body in terms of dimensions than it does in conventional drives is the case, and its foundation can be made small and therefore inexpensive.
  • the inventive arrangement of the gear housing laterally below the rotating body significantly reduces the space requirement for the entire system laterally. This is due to the fact that the gear housing comes to rest at least partially in the area below the rotating body, and only a part protrudes laterally beyond the contour of the rotating body.
  • the drive is preferably arranged vertically below the rotating body.
  • the entire gear housing now lies within the contour of the rotating body and no additional space is required and no additional foundation is required.
  • the pinions can, if necessary, also take over the mounting of the rotating body arranged above, ie the corresponding supports can be replaced or. do not have to be provided at all. Overall, this leads to a further simplification of the construction of the entire system.
  • Another advantage of this arrangement is that no additional mounting brackets have to be provided for the drive, but the drive directly next to the rotating body on the floor or. Foundation of the plant can be attached. This facilitates both the Assembly as well as maintenance and servicing work on the drive.
  • the drive according to the invention is suitable in principle for all types of plants with horizontally arranged rotating bodies, but preferably for plants in large dimensions, such as ball mills or cement mills.
  • FIG. 1 shows schematically the end view of a drive according to the invention
  • Fig. 2 shows schematically the end view of a further preferred embodiment of the drive according to the invention.
  • the gear housing 1 of the drive for a cylindrical rotating body 2 is shown in the front view with respect to the axis of rotation 3 of the rotating body 2.
  • the rotating body 2 is, for example, the grinding drum of a cement mill, the outer contour of this rotating body being only shown in dashed lines for the sake of clarity.
  • the gears are arranged in the form of a reduction gear, the two output pinion 4 respectively. 4 'protrude from the housing cover 5 of the gear housing 1 to the outside in the direction of the axis of rotation 3 of the rotating body 2.
  • the engagement of the upper drive pinion 4 takes place at an angle ⁇ of at least approx. 25 ° -40 ° with respect to the horizontal transverse axis of the rotating body 2.
  • the lower pinion 4 ′ thus has an engagement angle of approx. 40 ° to 55 °.
  • Gear housing 1 laterally only slightly from the outer contour of the rotating body, which means a significant space saving compared to conventional drive arrangements.
  • the overall width of such a system can thus be reduced in comparison to conventional systems, i.e. less installation space is required for the same length and volume of the system.
  • FIG. 2 also shows schematically the front view of a further preferred embodiment of the drive according to the invention.
  • the two pinions 4 and 4 respectively. 4 ' symmetrically with respect to the vertical axis 7 of the rotary body 2 from below the ring gear 6.
  • the two pinions 4, respectively. 4 'at the same time serve as a support for the rotating body 2 at this point.
  • the motor of the drive according to the invention is flanged to the drive shaft of the transmission in a conventional manner, preferably via a coupling.
  • the drive axis thus preferably comes to lie parallel to the axis of rotation of the rotary body 2 and the lateral dimension of the entire drive is not enlarged compared to the outer dimension of the transmission housing 1.

Abstract

L'invention concerne un dispositif d'entraînement destiné à un corps rotatif (2) disposé de façon à pouvoir tourner autour de son axe longitudinal (3) qui s'étend sensiblement horizontalement. Ce dispositif d'entraînement est disposé sous le corps rotatif (2) latéralement de sorte que les pignons de sortie (4, 4') s'engrènent avec la couronne dentée (6) du corps rotatif (2) selon un angle, formé par l'horizontale et une ligne partant vers le bas, compris entre 35 DEG et 90 DEG . Grâce à cet agencement du carter de transmission (1), l'encombrement latéral de l'installation complète est sensiblement réduit. Il est en outre avantageux que ledit système d'entraînement puisse être directement monté sur le sol ou sur la semelle de l'installation et que donc aucune console supplémentaire ou aucune semelle supplémentaire ne soit nécessaire.
