Definitions

  • the invention relates to a guide rail for motor chain saws with a circumferential guide groove for guiding the chain and at least one lubricant channel leading to the guide groove.
  • the guide rail is characterized in that the lubricant channel is formed in the bottom of the guide groove.
  • the conventional known lubricant channels are provided in the center of the guide rail, and branches of the lubricant channels lead to the bottom of the guide groove.
  • the invention is characterized in that the lubricant channel and the guide groove are designed as a groove which is subdivided by an insert base into the lubricant channel and the guide groove, the insert base having outlet openings for the lubricant.
  • Fig. 1 shows schematically the view of a motor chain saw.
  • Fig. 2 is a partially sectioned side view of a guide rail according to the invention and
  • Fig. 3 is a section along the line III-III in Fig. 2.
  • Fig. 4 is a section along line IV-IV in Fig. 2 by an embodiment of the formation of the guide groove with lubricant channel.
  • 5 to 9 show different variants of this design of the guide groove with lubricant channel.
  • 10 to 12 are further exemplary embodiments for the construction of the guide groove.
  • Fig. 1 shows a side view of the basic structure of a motor chain saw. It comprises a motor 1, the housing of which has handles 2.
  • the guide rail 3 guides the saw chain 4 in a peripheral guide groove, which is shown only schematically here.
  • the saw chain 4 is endless and is held in circulation by a pinion driven by the motor 1. 1 is only roughly schematic.
  • Fig. 2 shows a partially sectioned embodiment of the guide rail according to the invention.
  • This guide rail 5 has a groove 7 along the two slightly curved flanks 6. This groove is divided by the insert base 8 into the guide groove 9 and the lubricant channel 10.
  • the lubricant passes from a lubricant pump, not shown here, via the nipple 11 into the lubricant channel 10, which transports the lubricant over the entire length of the guide rail.
  • the lubricant enters the guide grooves 9 on both sides of the guide rail through the outlet openings 12 in the insert base 8 and thus lubricates the saw chain.
  • the two end regions 13 of the lubricant channel 10 are preferably closed.
  • the drive pinion 14 for driving the saw chain is only indicated schematically. The saw chain is not shown.
  • the guide roller 15 At the outer end of the guide rail 5 there is a deflection roller 15. A section is shown in FIG. 3. In cross section, the guide roller 15 also has the guide groove 9, so that the saw chain also is adequately guided in the front deflection area. The deflection roller 15 reduces the friction in the deflection area and with such chainsaws it is also possible to pierce the workpiece to be sawn.
  • the deflecting roller 15 is held by two cheeks 16, which are firmly connected to the guide rail 5 with tabs 17.
  • the bearing is carried out on the axis 18 by means of roller or needle bearings 19. Since the guide rail is constructed essentially in one piece, this deflecting roller construction can be provided with the necessary strength.
  • the training floor can be designed in a variety of ways and the choice can be adapted to the respective requirements.
  • the insert base is by a rod-shaped spring 20, which is arranged at a suitable height in the groove 7 and z. B. is fixed by spot welding.
  • the area of the groove 7 which is open to the flank 6 is the guide groove 9 and the area below the insert base up to the groove base 31 forms the lubricant channel 10.
  • One of the outlet openings 12 is shown in FIG. 4.
  • the saw links 22 have the saw tooth 24 on the outside and protrude with their foot 25 into the guide groove 9.
  • the foot 25 also has a notch (not shown here) in which the teeth of the pinion 14 engage and thus drive the saw chain.
  • the flanks 6 of the guide rail 5 also form the sliding surfaces on which the chain rests under tension.
  • the two legs 26, 27 of the connecting member 23 serve as sliding bodies. 28 is the rivet, which in each case connects the connecting member and the saw member pivotably to one another.
  • the lubricant channel 10 is formed in that a step 29 is provided in the groove, and the insert base 30 rests on this step and, if necessary, is connected to the surrounding material.
  • the groove 7 is milled or ground in during the machining of the guide rail and an insert piece which has the shape of a tube or hose 32 is placed on the groove base 31.
  • This hose or tube 32 is provided over the entire length of the guide rail 5 and releases the lubricant upwards through the outlet openings 12.
  • 7 to 9 show further shapes for insert pieces, as can be used according to the invention.
  • 7 and 9 are insert pieces in the form of shaped pieces 33 with the cross section shown in each case.
  • the insert is in several parts and is formed from three rod-shaped elements 34, 35.
  • the outlet openings 12 are each formed in that corresponding bores are arranged in the insert bases or insert pieces.
  • the location of the holes can be easily adapted to the needs in the course of production.
  • the outlet openings 12 are arranged at a smaller distance than in the rear part in the vicinity of the lubricant supply via the nipple 11. This ensures a uniform distribution of the lubricant.
  • the outlet openings 12 can, for example. also be formed in that the insert bases or insert pieces are not provided continuously over the entire length of the groove 7, but rather section by section with the release of corresponding gaps through which the lubricant can escape.
  • a guide rail is prepared which ends at the line drawn in 36. Only the lubricant channel 37 is milled and closed at the top by the insert 38. Thereafter, by suitable material, such as. Stellite or a solid plastic built up material that forms the flanks 39 for the guide channel 40 to be ground. The flank surface 6 is then the sliding surface for the chain.
  • a conical groove 42 and the lubricant channel 37 are milled into the material 41 of the guide rail.
  • the conical groove 42 is, for example, by means of casting material. Plastic or Stelitte or the like. Wear-resistant material built into which the guide groove 40 can be ground.
  • FIG. 12 shows a further embodiment, in which the guide groove 40 and the lubricant channel 37 are lined entirely or in large part by an insert 43, the liner also forming the flank 6 for supporting the saw chain.
  • Lubricants are all liquids that are useful for sawing, such as those based on oil (natural and synthetic) and water-based.
