Definitions

  • the invention relates to a roller bearing for a cone crusher, in which a vertically arranged drive part is rotatably mounted on a foot part, at the upper end of which a crusher cone is inclined to the vertical and is freely rotatable.
  • DE-OS 34 01 722 shows such a roller bearing, in which a vertical shaft driven by a motor is mounted in a foot part by means of a roller bearing. At its upper end, this shaft carries a second roller bearing, which is inclined and eccentrically offset to the first roller bearing and which, on the other hand, supports the crusher cone. Since these roller bearings are unprotected to the outside, complex sealing measures had to be used in this known embodiment in order to adequately protect the bearings against the dust accumulating during operation.
  • the invention has for its object to provide a more compact, thus easier and cheaper storage for a cone crusher compared to the known prior art, which also has much lower sealing problems than the known bearings.
  • the roller bearing consists exclusively of a common hollow cylindrical outer part, in which two inner rings lying axially one behind the other are located over roller bodies support, there is, the outer part is part of the drive part, and the first inner ring is connected to the foot part, while the second, which is inclined and eccentrically offset to the first, carries the crusher cone.
  • the common outer ring covers the interior containing the rolling elements, there is only a gap to be sealed between the upper end of the outer race and the crusher cone, which gap can be sealed in a known manner by labyrinth seals.
  • the bearing gap is located at the lower end in the area of the foot part in which the drive means are also located. This space is separated from the part of the cone crusher in which dust is generated.
  • a first inner ring 2 of a roller bearing is screwed, between which and the outer ring 3 of the roller bearing roll cylindrical rollers 4, which are arranged in a known manner as cross rollers, that is, that the axes of successive cylindrical rollers in a known manner at an angle of 90 ° to each other.
  • a ring gear 5 is screwed, in whose teeth the bevel pinion 6 engages, which on the z. B. is fastened in a manner not shown driven by an electric motor drive shaft 7.
  • the invention is not limited to a roller bearing in which crossed rollers are used as the rolling elements. Rather, any known roller bearing can be used, which is able to absorb radial and axial forces, as well as occurring tilting moments.
