Definitions

  • the invention relates to a trench cutter according to the preamble of claim 1.
  • a trench wall cutter with these features goes for example from the EP-0 848 112 B1 out.
  • the lower bearing of the drive shaft is lubricated by the gear oil in the gearbox. Due to the increased distance between the gearbox in the bearing plate and the drive, the upper bearing of the drive shaft can not or hardly be lubricated directly by lubricants from the gearbox housing. There is a risk of increased bearing wear due to insufficient lubrication.
  • US 4,764,135 discloses a stern drive for a ship in which oil is circulated between a lower housing and an upper housing by means of a threaded shaft and a grooved sleeve.
  • the invention is therefore an object of the invention to provide a trench wall cutter with generic features, in which the maintenance is kept very low.
  • the drive shaft has an external thread, which is designed as a conveying thread for conveying lubricants in the direction of the drive.
  • a basic idea of the invention is to convey lubricant from the gear box to the elements of the attachment of the drive to the drive shaft to be lubricated by the drive shaft which extends from the gear box to the drive.
  • the drive shaft is formed with an external thread, which is used as a conveying thread for conveying the lubricant upon rotation of the drive shaft.
  • a distributor device for further distributing the lubricant.
  • This distributor sprays the lubricant delivered by the drive shaft.
  • the distributor can be injection lugs or edges on the output shaft.
  • this device has a toothing. This gearing can be used both for transmitting the torque of the drive to the drive shaft, as well as for distributing the lubricant. This is particularly simple because the drive shaft is set in motion for transmitting the torque of the drive and the lubricant is sprayed by the rotation and the teeth in the connecting sleeve.
  • At least one bearing in particular rolling bearing, is arranged, and the drive shaft is designed for lubricating the at least one bearing.
  • At least one seal in particular a sliding seal, is arranged in a region of the output of the drive and the drive shaft is designed for lubricating the at least one seal.
  • the trench wall cutter is further characterized in that a connecting sleeve is arranged between the drive and the drive shaft, on the outside of which the at least one bearing, particularly preferably and the at least one seal, is arranged.
  • a connecting sleeve is arranged between the drive and the drive shaft, on the outside of which the at least one bearing, particularly preferably and the at least one seal, is arranged.
  • FIG. 1 The basic structure of a trench wall cutter 10 'is in FIG. 1 shown.
  • a pair of Fräsradnaben 19 are arranged, which are driven by a Fräswelle 13.
  • the cutting wheels can be releasably secured.
  • the drive shaft 13 is connected to a ring gear 15 which is rotatably supported on the bearing plate 12 via crown gear bearing 16.
  • the ring gear 15 meshes with a drive pinion 17 whose axis of rotation extends substantially perpendicular to the cutting wheel shaft 13.
  • the drive pinion 17 is in turn rotatably mounted in the bearing plate 12.
  • the drive pinion 17 is connected via a first non-rotatable connection 23 with a drive shaft 20 ', which parallel and centric to the drive pinion 17 after extends to the top of the drive.
  • a second rotationally fixed connection 24 ' which in this case is a tongue and groove connection. This serves to connect to a coupling element 31, via which the torque from the drive to the drive shaft 20 'is transmitted.
  • the drive shaft 20 ' is rotatably supported by a drive shaft bearing 22, which is arranged liquid-tight in a bearing housing 30.
  • a holder 32 is provided on the cutter frame 40, over which the trench wall cutter 10 'can be transported.
  • Fig. 1 The related to Fig. 1 described components, which are designated by a reference numeral without quotation mark, can be provided in the trench wall cutter 10 according to the invention substantially without much change.
  • FIG. 2 shows a trench wall cutter 10 according to the invention on a drive shaft 20 is located at the lower end in the bearing plate 12, a gear coupling 25. At the other, upper end of the drive shaft 20, a distribution device is attached.
  • the drive shaft 20 is located in a gear plate 21 which is adjacent to the external thread 44 of the drive shaft 20.
  • the oil level 45 in the transmission of the trench wall cutter 10 extends to the lower end of the drive shaft 20.
  • the distribution device 24 has a spray edge.
  • the Vereilungs pleased 24 also designed as a component with an external arc toothing. Due to the radial splashing of the lubricant located in the connecting sleeve 46 ball bearings 49 are supplied with sufficient lubricant. Likewise, the mechanical seal 50 is protected from drying out by the splashing of the lubricants. Both the drive 48 and the connecting sleeve 46 are protected in the milling frame 40. Excess lubricant can from the upper region via an annular channel 27 and a return bore 28 down to the transmission be removed and cooled there.
