Definitions
- the invention relates to a clamping device for grinding wheels with clamping elements which are formed by two clamping flanges or a clamping flange and a clamping nut and, if appropriate, a damping insert.
- Low-noise grinding wheels have already been developed to reduce noise during grinding. Although this did lead to a reduction in noise pollution, on the other hand it led to less abrasion of the grinding wheels, which significantly reduced the work progress and the profitability of the grinding wheels.
- the object of the invention is to improve a tensioning device of the type mentioned at the outset such that a reduction in noise is achieved when using a conventional grinding wheel without special damping.
- the object of the invention is achieved in that a stiff, preferably metallic intermediate ring is arranged between at least one clamping element and the grinding wheel, which spacers the grinding wheel from the clamping element and that The intermediate ring or the clamping element adjacent to the intermediate ring is provided with a fixed damping layer made of elastic material, which extends both in the radial and in the axial direction.
- tensioning element, the damping layer and the intermediate ring are connected to one another, for example glued to one another.
- damping layer extends both in the radial and in the axial direction and an increased service life of the grinding wheel is achieved with reduced noise and vibration loads.
- FIG. 1 to 4 show sections through different exemplary embodiments of a clamping device according to the invention, in each of which a grinding wheel is clamped
- FIG. 5 shows a section through a clamping device according to the invention, the parts of the clamping device being drawn apart.
- the clamping device according to the invention consists of two clamping elements, one of the clamping elements being formed by a clamping flange 1 and the second clamping element being formed by a clamping nut 2 in the exemplary embodiments shown.
- the invention can also be used in a clamping device with two clamping flanges.
- an intermediate ring 5 is further arranged between the clamping flange 1 and the grinding wheel 3, 4, which is preferably made of the same material as the clamping flange 1 and the clamping nut 2, for example a cast steel or sheet steel.
- a grinding wheel is in the clamping device
- the intermediate ring 5 has a projection 7 pointing towards the clamping nut 2, which protrudes into the hub opening 8 of the grinding wheel 3 and which in the exemplary embodiment rests on the inside of the grinding wheel 3
- damping layer 9 made of an elastomeric material.
- the damping layer 9 is ring-shaped and has a disk-shaped area 10 and a sleeve-shaped area 11
- the diameter of the hub opening 8 of the grinding wheel 3 is more than a quarter of the outer diameter since the grinding wheel 3
- This large ratio makes the grinding wheel 3 more rigid when used. There is less waste in relation to the total mass of the grinding wheel 3 and the proportion of the damping mass of the damping layer 9 can be increased in relation to the mass of the grinding wheel 3
- the clamping device in the exemplary embodiment according to FIG. 2, is provided with a grinding wheel 4, which is designed as a cutting disc.
- the clamping device in turn has a clamping flange 1, a clamping nut 2 and an intermediate ring 5, in this exemplary embodiment a damping layer 9 analogous to that previously described exemplary embodiment is provided and a further annular damping layer 12, which is located between the grinding wheel 4 and the clamping nut 2
- a grinding wheel 4 designed as a cutting wheel is again held in the clamping device.
- the intermediate ring 5 is on the hub side provided with a sleeve-shaped projection 13 on both sides of the intermediate ring
- the damping layer 14 between the clamping flange 1 and the intermediate ring 5 has a radial section 15, an axial section 16 which is arranged between the sleeve-shaped projection 13 and the clamping flange 1, and a further radial section 17 which the sleeve-shaped projection 13 of the intermediate ring 5 separates from the clamping flange 1. Between the sleeve-shaped projection 13 and the sleeve-shaped area of the clamping nut 2 is provided in the game.
- the sleeve-shaped projection 13 projects into the hub opening 8 of the grinding wheel 4.
- a damping layer 12 is again provided between the grinding wheel 4 and the clamping nut 2.
- the damping layer 14 also serves as an adhesive layer, so that the parts 1 and 5 can be handled by the user as a common part.
- the intermediate ring 5 is in turn connected to the clamping flange 1 via a damping layer 9, which is also designed as an adhesive layer.
- the clamping nut 2 is screwed in a conventional manner to the output shaft of a grinding machine, for example a hand-held grinding machine.
