Definitions

  • the invention relates to a motor chain saw according to the preamble of claim 1, such a motor chain saw is in WO 2011/098097 disclosed.
  • the pump drive of the feed pump consists of a first drive wheel connected to the feed pump and a second drive wheel connected to the sprocket, which are in drive connection with one another.
  • the second drive wheel is designed as a worm wheel on a drive element which engages over the sprocket with a coupling section in such a way that it is in a form-locking drive connection with the sprocket.
  • the coupling portion has for this purpose on the circumference of a plurality of drivers, which are associated with driving surfaces formed on the sprocket. In this case, all drivers engage between two teeth of the driving sprocket and are in driving connection with this.
  • the sprocket must be replaced according to the type of saw chain used to ensure the shape and pitch of the saw chain adapted drive connection with the sprocket. If the geometry of the sprocket is changed, the drive element to the feed pump must be replaced, since the coupling portion is formed in each case according to the geometry of the sprocket used.
  • the invention has for its object to simplify the structure of the drive connection between a sprocket and a drive element for driving a feed pump.
  • a plurality of first driver are formed, which are associated with a first sprocket first geometry; in the same coupling portion of the same drive element a plurality of second drivers are formed, which are associated with the second sprocket of a second geometry.
  • the first geometry is different from the second geometry.
  • the first geometry differs from the second geometry z.
  • the drivers are arranged such that the coupling portion rests with the first or second drivers on the respectively associated first or second driving surfaces of the driving first or second sprocket.
  • the same drive element for multiple sprockets of different geometry can be used, so that when replacing the shegekettengarnitur usually the drive element does not need to be replaced. This simplifies the replacement of a shegekettengarnitur in a motorized chainsaw.
  • the driver surface is preferably formed on a chain tooth itself, so that no special engagement means on the sprocket itself are necessary.
  • the driver overlaps the sprocket tooth over a partial width axially, wherein the partial width is smaller than 30% of the total width of the sprocket tooth. This size of the driving surface is sufficient for a pump drive.
  • two first drivers and two second drivers each form a driver pair, wherein a driver pair in the circumferential direction - so in both directions of rotation of the sprocket - each defines a receptacle for an associated sprocket of the first and second sprocket.
  • the training is advantageously provided such that in the circumferential direction of the drive element alternately a first driver pair and a second driver pair successive.
  • the first receptacles provided in the coupling section relative to the axis of rotation of the drive element are diametrically opposed to one another and the second receptacles each lie diametrically opposite one another. This allows an arrangement of the driver to an axial plane of the drive element carried out such that they are symmetrical to this axial plane.
  • a first receptacle formed by first drivers is formed in the circumferential direction of the drive element with a smaller extent than the extension of a second receptacle formed by second drivers.
  • the first receptacle has a smaller extent in the circumferential direction than the second receptacle.
  • the empty distance between the driver pairs in the circumferential direction of the drive element is at least twice as large as the maximum extent of a receptacle in the circumferential direction.
  • a sprocket of a driving sprocket is held in the circumferential direction of the drive element in the associated receptacle of a pair of carriers with such tolerance that easy manufacturing and assembly of the drive element is ensured on the sprocket. It may be appropriate to keep the driving sprocket in the receptacle substantially free of play.

  • the inventive design of the positive drive connection from the pushed onto the existing metal sprocket, consisting of plastic drive element is thus designed so that - regardless of the geometric design of the recorded in the drive connection sprocket - only a subset of the sprockets of the driving sprocket with the drivers be in drive connection. It is advantageous that the drivers lie with radial play to the tooth base between two chain teeth. Due to the different geometry of the sprockets used, the drive element facing connection contour of the sprocket in shape, shape and / or geometry is different; Despite the different connection diagrams of the connection contour of the sprocket can be used according to the invention the same drive element for the pump drive.
