Definitions
- the invention relates to a clamping device for grinding wheels Clamping elements, wherein between at least one clamping element and the Grinding wheel is a rigid, preferably metallic intermediate ring is arranged the grinding wheel is distanced from the clamping element and the intermediate ring or the clamping element adjacent to the intermediate ring with a fixed one Damping layer is made of elastic material, which is both radial and extends in the axial direction.
- the object of the invention is to provide a tensioning device of this type improve that when using a conventional grinding wheel with less Clamping elements good damping and exact centering of the grinding wheel is achieved.
- the object of the invention is achieved in that the intermediate ring one has hub-shaped sleeve-shaped projection and that the intermediate ring and that Clamping element through the damping layer made of elastic material, which is extends both in the radial and in the axial direction, fixedly connected to one piece are.
- both thin (e.g. Cutting wheels), as well as thick grinding wheels because of the Clamping flange and the flange nut are shaped to fit together.
- damping layer is both radial extends as well as the axial direction and with reduced noise and vibration exposure an increased service life of the grinding wheel is achieved.
- 1 to 4 show sections through various embodiments of a clamping device according to the invention, in each of which a grinding wheel is clamped, and 5 shows a section through a tensioning device according to the invention, the parts of the tensioning device being drawn apart.
- the tensioning device according to the invention consists of two tensioning elements, wherein in the exemplary embodiments shown one of the clamping elements of a clamping flange 1 and the second clamping element is formed by a clamping nut 2.
- the invention can also be used for a clamping device with two clamping flanges come into use.
- the clamping flange 1 is provided with a damping layer 9.
- an intermediate ring 5 is arranged, which preferably consists of 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 3 stretched, the cranked grinding wheel with an annular rough grinding layer 6 is formed.
- the intermediate ring 5 has a projection 7 facing the clamping nut 2, which in the hub opening 8 of the grinding wheel 3 protrudes and the inside in the embodiment the grinding wheel 3 rests.
- damping layer between the intermediate ring 5 and the clamping flange 1 9 made of an elastomeric material.
- the damping layer 9 is just like the intermediate ring 5 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 outside diameter since the grinding wheel 3.
- This size ratio makes the grinding wheel 3 stiffer when used. It happens in relation to the total mass of the grinding wheel 3 less waste and Share of the damping mass of the damping layer 9 can in relation to the mass the grinding wheel 3 can be increased.
- the tensioning device according to the invention is included a grinding wheel 4, which is designed as a cutting wheel.
- the tensioning device again has a clamping flange 1, a clamping nut 2 and an intermediate ring 5, with a damping layer 9 in this exemplary embodiment is provided analogously to the previously described embodiment and another annular damping layer 12, which is between the grinding wheel 4 and the clamping nut 2 is located.
- the intermediate ring 5 is on the hub side provided with a sleeve-shaped projection 13 on both sides of the intermediate ring 5 protrudes.
- the damping layer 14 between the clamping flange 1 and the intermediate ring 5 has a radial section 15, an axial section 16, which between the sleeve-shaped projection 13 and the clamping flange 1 is arranged, 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 protrudes in on the side assigned to the clamping nut 2 the hub opening 8 of the grinding wheel 4.
- damping layer 12 Between the grinding wheel 4 and the clamping nut 2 there is in turn a damping layer 12 provided.
- the damping layer 14 also serves as an adhesive layer, so that parts 1 and 5 can be handled by the user as a common part.
- the intermediate ring 5 is in turn with the Clamping flange 1 via a damping layer 9, which is also designed as an adhesive layer is connected.
- the clamping nut 2 is formed by a core part 18 and an outer ring part 19. These two parts 18, 19 are in turn by means of a damping layer 20, for example is formed by a butyl rubber, glued.
- the clamping nut 2 is conventional in the exemplary embodiments shown Way with the output shaft of a grinding machine, such as a hand grinder screwed.
