Definitions
- Such a fan-grinding wheel is from the EP 1 142 673 B1 known.
- the grinding blades are square. They have two mutually parallel straight edges and a concave and a convex edge.
- the convex and the concave edges are each in the form of a circular arc whose radii are the same, but the centers of the radii are offset from each other on a line parallel to the straight edges.
- the advantage of this embodiment of the grinding blades is that they can be cut without waste, so waste free from a grinding belt with mutually parallel edges.
- the abrasive flaps are attached overlapping each other on the edge region of the support plate, whereby a portion of the outer edge of the abrasive flake package is formed by the convex edge of each abrasive flake.
- the invention is based on the object, a fan-grinding wheel of the aforementioned kind so ausgestalten that their life is further increased.
- the claims 7 and 8 give advantageous embodiments of the inner edge again, wherein the embodiment according to claim 7 has the advantage that the grinding blades can be cut to save space from a grinding belt.
- the embodiment according to claim 8 is particularly preferred when the abrasive slats are not cut from ribbons from a roll, but from sheets, so there may be interleaved.
- the claims 12 and 13 relate to the fact that the grinding lamellae have a true triangular shape, so that in each case two major edges, whether rectilinear or curved, intersect at an intersection.
- the claims 14 and 15 relate to a particularly preferred embodiment, according to which the corners of the respective triangle are rounded, by convexly curved side edges whose radii of curvature are significantly smaller than the curvature radii of the main edges.
- the advantage of this embodiment is that both the production of the punching tools and the detachment of the abrasive flaps after punching from the strip material is simplified. The production of real sharp corners in the punching tools is more complex.
- the detachment of a triangular in the true sense abrasive slat from the strip material is more difficult than the detachment of a grinding blade with rounded corners.
- the embodiments according to the Claims 12 on the one hand and 14 on the other hand also include hybrid forms between these two embodiments.
- grinding blade 1 is triangular. Their three edges are referred to as outer edge 2, inner edge 3 and trailing edge 4 according to their later position on a support plate of a fan grinding wheel.
- the edges 2 to 4 are formed as circular arc sections with a corresponding radius of curvature R2, R3 and R4.
- the outer edge 2 and the trailing edge 4 are - with respect to the grinding blade 1 - convex, while the inner edge 3 is concave.
- Even with such geometric shapes are triangles, since according to the rules of spherical geometry, the boundary lines of a triangle need not be rectilinear, but can also be curved; It is crucial that two side edges intersect at one point of intersection, ie form a corner.
- the support plate 5 has an outer annular edge region 8 for receiving the grinding blades 1.
- This edge region 8 is connected to the hub 6 via a projecting in the direction of the central axis 9 of the support plate 5 annular web 10.
- the edge region 8 is inclined radially outward against the annular web 10, such as Fig. 3 is removable.
- the working surface 11 of the grinding lamellae 1 to be arranged on the support plate 5 again runs essentially radially and perpendicular to the central axis 9.
- Fig. 2 This geometry results from the fact that more and more abrasive lamellae 1 overlap or overlap one another from inside to outside, such as Fig. 2 is removable.
- the grinding blades 1 are fastened on the edge region 8 of the support plate 5 by means of an adhesive layer 12.
- Fig. 2 can be removed, the grinding blades 1 are arranged on the support plate 5 at equal angular intervals, in each case rotationally symmetrical in the same position to the support plate 5.
- the outer radius R13 of the grinding lamella packet 13 fastened on the support plate 5 corresponds to the radius of curvature R2 of the outer edge 2, so that the outer edge 14 of the abrasive lamella packet 13 projecting outwardly beyond the edge region 8 is circular.
- abrasive blade 1 is shown in dashed lines, although their respective abrasive region 15 extends only from its trailing edge 4 to the next in the direction of rotation 16 of the grinding wheel leading edge arranged 4.
- Fig. 2 can be removed, form the tangent 17 to the trailing edge 4 at the intersection 18 with the outer edge 2 and the radius R13 through the intersection 18 an angle ⁇ > 0 °, the tangent 17 with respect to the radius R13 in the direction of rotation 16 leads.
- angle ⁇ is 5 ° ⁇ ⁇ ⁇ 35 °.
- each grinding lamella 1 extends over an angle ⁇ of the annular abrasive lamella package 13, wherein 25 ° ⁇ 90 °.
- ⁇ the angle of the annular abrasive lamella package 13
- Fig. 4 It can be seen how the grinding blades 1 are cut from a grinding belt 20.
- the width a of the sanding belt 20 is selected so that the intersection point 21 of the outer edge 2 and the inner edge 3 lies on a longitudinal edge 22 of the sanding belt 20, while the point of intersection 23 between the inner edge 3 and the trailing edge 4 on the other longitudinal edge parallel to the longitudinal edge 22 24 is located.
- the point of intersection 18 between the outer edge 2 and the trailing edge 4 abuts against the inner edge 3 of the adjacent grinding blade 1 to be cut out.
- abrasive blade 1 has the already described outer edge 2 and trailing edge 4.
- the inner edge 3 ' is formed in a straight line. Their radius of curvature R3 'is therefore infinitely long.
- FIG. 7 the design of a grinding lamella 1 "', in which not only the inner edge 3' and the trailing edge 4 ', but also the outer edge 2' are rectilinearly formed, whose radius of curvature R2" therefore also has an infinite length.
- the embodiments of the 8 to 11 in their basic structure correspond to those according to the Fig. 1 . 5 . 6 . 7 , wherein instead of the sharp-edged intersections 18, 21, 23 respectively rounded corners are provided.
- These abrasive slats thus each have the basic shape of a triangle.
- the main edges forming outer edges, inner edges and trailing edges are thus connected to each other by convexly curved side edges whose radius of curvature r each is significantly smaller than the radius of curvature R of the mentioned main edges.
- the main edges forming outer edges, inner edges and trailing edges are in the 8 to 11 with the same reference numerals as the corresponding edges in the Fig. 1 . 5 . 6 . 7 denotes, in each case an "a" is added to distinguish. The same applies to the radii of curvature R.
- the side edges are provided with the same reference numerals, as the intersections 18, 21, 23, wherein these are added to distinguish an "a". The same applies to the name of the radii of curvature r of the minor edges.
- Fig. 8 At the grinding blade 1a after Fig. 8 are all three major edges, namely the outer edge 2a, the inner edge 3a and the trailing edge 4a curved, namely the outer edge 2a and the trailing edge 4a convex, while the inner edge 3a is concavely curved.
- the radii of curvature are R2a, R4a and R3a.
- the major edges are connected to each other by three side edges 18a, 21a and 23a, respectively, which are convexly curved and have radii of curvature r18a, r21a and r23a, respectively.
- the grinding blade 1'a after Fig. 9 is different from the after Fig. 8 in that the inner edge 3'a is rectilinear and consequently the radius of curvature R3'a of this inner edge 3'a has an infinite length.
- the grinding blade 1 "a to Fig. 10 differs in turn from the after Fig. 9 in that also the trailing edge 4'a is rectilinear and consequently its radius of curvature R4'a has an infinite length.
- the radii of curvature R of the main edges are significantly larger than the radii of curvature r of the minor edges.
- the ratio of the radii of curvature R of the main edges to the radii of curvature applies r of the minor edges: 3 ⁇ R / r ⁇ 20 and preferably 10 ⁇ R / r ⁇ 20.
