Definitions
- the present invention relates to a master sheet for Circular saw blades and / or cut-off wheels according to the Preamble of claim 1, see US-A 3 315 418.
- US-A-3 315 418 describes a plastic grinding wheel, which is a fiber reinforcement made essentially circular extending fibers and radial fibers.
- Several fiber layers are provided, each Location from a combination of essentially circular Fibers and radial fibers. They are also individual fibers are also relatively far apart, i.e. it is a relatively small number of fibers or low fiber density.
- a circumferential grinding wheel is known from DE-C-27 40 891, which consists of an inner hub part and an outer, a grinding ring made of rim parts carrying grinding wheels exists, with hub and rim over preloaded - and thus performing the function of "spokes” - wires, fibers or Threads are interconnected.
- spokes embedded in plastic.
- the "spokes” is said to be a common one in the plastic, of fabric mats formed fiber reinforcement can be embedded.
- DE-A-2 045 814 describes a synthetic resin saw blade, which radially running, with 7.5 cm relatively wide bands contains boron epoxy. Each volume in turn contains in the longitudinal direction of the belt and therefore parallel to each other Boron threads. The individual ribbons run together crossing radially through the center of the leaf. The Boron threads are primarily used for production the cutting action by placing it on the outer circumference of the sheet end and act as a "cutting or grinding surface".
- the present invention is therefore based on the object eliminate the problems outlined and starting out from the mentioned prior art to a master sheet create which under practically all operating conditions ensures optimal running properties and machining results, and which also has a long lifespan owns.
- this is achieved in that the two types of fiber flow in different fiber layers on the one hand only with the radial course and on the other hand are only arranged with the circular course, where a plurality of the fiber layers with one in Depending on the size of the disc body chosen Distribution of the two different types of layers one above the other and integrally connected in the disc body is arranged, the fibers such are arranged close to each other in the area of the fiber layers a fiber density with a volume fraction of about 60 to 70 vol .-% is present.
- the respective radially aligned fibers effect high stability of the master blade in the radial direction
- the substantially circular fibers stabilize the blade in the circumferential direction, i.e. against bending around the radial direction, being a particular advantage
- the mechanical properties practical about the scope of the master sheet according to the invention are absolutely constant, because in contrast to the state the technology is based on the fiber orientation according to the invention and distribution practically an "isotropy" within of the master sheet reached.
- each fiber layer is one has a central opening, so that it is thus an annular disc is formed, the individual fiber layers of the master sheet with regard to their inside / outside diameter ratio especially different sizes are.
- the distribution of these changes in their diameter ratios distinctive fiber layers within the Master sheet also takes place according to the invention in Adaptation to the dimensions (diameter, thickness) of the Master blade in such a way that an optimal "stability distribution" within the master sheet according to the invention can be reached.
- the fibers are thus as accurate as possible aligned in the respective orientation are included but essentially free of tension in the plastic material of the master sheet embedded.
- the radial fibers end at both ends "blind", i.e. they are - apart from to a material bond existing over its entire length the plastic material - not particularly supported at the end, i.e. not "tied up”.
- the essentially circular Aligned fibers can be found in the corresponding Layers are advantageously laid as a continuous material in spiral form be so that the alignment is very slightly different from the ideal Circular shape differs, but this does not cause any disadvantage.
- the fibers are like this in every fiber layer arranged closely next to each other that a high fiber density is achieved.
- the volume fraction of the The fiber material is about 60-70% by volume.
- the elastic properties of the master sheet according to the invention are even better than those of a master sheet from steel.
- the master sheet according to the invention is characterized by optimal Running properties under almost all operating conditions, due to its low weight and long Service life (durability).
- a master sheet 1 according to the invention is simplified, i.e. without extensive cutting elements.
