Definitions
- the invention relates to a guide rail and link chain for a chain saw for processing concrete, stone and masonry with coolant channels guided through the guide rail and cutting plates placed on the chain links.
- Such a link chain for a chainsaw is known from the publication DE 33 32 051 AI.
- the guide rail, also known as the sword, of a chainsaw is provided on the long sides with additional rails made of metal.
- the guide rail is hollow, this cavity serving as a coolant channel, and coolant channels are arranged on the side faces of the additional rails.
- the associated link chain consists of rollers mounted on pins which are connected to one another via guide and connecting links. The rollers run on the outer surface of the additional rail, and the chain is deflected via a chain wheel at the front end of the bar. Diamond-tipped inserts, which serve as cutting tools, are attached to the chain guide elements.
- the guide rail / link chain system according to the invention has a significantly longer service life than the known chain saws. This is achieved in that the guide rail or the sword of the chainsaw has plastic sliding rails on both longitudinal sides, on which metallic sliding elements of the chain slide. These slide rails are inserted in grooves, which are located on the long sides of the sword. Materials with high abrasion and water resistance are suitable as plastics. Since the coolant channels through the center area of the sword
- the components of the chain consist of flat elements that are not bent or bent, they can easily be ground to exact dimensions, making it possible to build an inexpensive chain. Since the inserts are attached to carrier plates, there is no danger that the hardened chain links will be softened by soldering. In addition, the cutting plates with their carrier plates can be attached to the chain links at the most convenient time for production, which in turn enables the chain to be manufactured more easily and more cheaply.
- a lubricant channel 25 is located in the center of the joints 5. This lubricant channel 25 is closed on one side by a pin 30 and has a ball valve 32 loaded with a spring 31 on the other side. One or more radial bores 26 extend from the central lubricant channel 25, which form lubricant channels and enable the lubricant to be supplied to the outer jacket 27 of the bolt 21.
- the ball valve 32 prevents water from penetrating, but enables water-resistant molybdenum grease to be pressed into the lubricant channels 25 and 26. The grease is pressed outward along the outer casing 27 of the bolt 21 and also fills the sliding surfaces between the sliding elements 6 and the side guide elements 7 and 8.
- the cutting plates 4 are fastened on carrier plates 28.
- the cutting plates 4 are normally fastened to the carrier plates 28 by brazing processes.
- the carrier plates 28 cover the full base of the cutting plates 4, which results in the greatest possible adhesion and contact area between the cutting plates 4 and the carrier plates 28.
- Corresponding cutouts are provided on the sliding elements 6 on the upper side 10, cams 29 engaging over the projecting edges of the carrier plates 28.
- the mounting of the carrier plates 28 in the recesses or on the cams 29 of the sliding elements 6 takes place by gluing or riveting the cams 29.
- This fastening method ensures simple and secure fastening and prevents the hardened ones from being fixed when the cutting plates 4 are fastened by soldering processes Sliding elements 6 are made soft again.
- Bolt 21 and the bearing bush 20 has a hardness of 55 to 65 Rockwell C, igzw. HRC, and the sliding or friction bearing elements 6 and the side guide elements 7 and 8, a hardness of 35 to 48 Rockwell C or HRC All known cutting and cooling agents for rock work can be used as coolants.
