Definitions

  • the invention relates to a grinding wheel with a carrier body, which has a central coupling area for connecting the grinding wheel to a rotary drive for rotating the grinding wheel about an axis of rotation running through the coupling area and a peripheral surface, and with a grinding pad, which is applied to the peripheral surface of the carrier body, in particular is sintered, the carrier body comprising a first part and a second part connected to it, the first part having the circumferential surface and exclusively the second part having the coupling region and consisting of a vibration-damping material.
  • the grinding wheel 101 comprises a carrier body 102 made of steel with a central coupling area 104 for connecting the grinding wheel 101 to a rotary drive for rotating the grinding wheel 101 about an axis of rotation 105 running through the coupling area 104
  • Carrier body 102 furthermore has a peripheral surface 106 on which an abrasive coating 107 is applied.
  • vibrations occur during grinding, which radiate over all areas of the grinding wheel and the workpiece to be machined. If one or more natural frequencies are excited, the vibrations are even amplified. The vibrations can also negatively influence the accuracy and thus the quality of the grinding result.
  • a grinding wheel with a first part, which is connected via a flange connection to a flange-like, second part made of a fiber-reinforced plastic, is known from the document EP 2 527 090 A1 forth.
  • the steel substrate of the first part is clamped between the two flange parts.
  • Another grinding wheel with a first part made of steel, which is arranged in a circumferential groove of the second part, is from the document CH 575 276 A5 known, wherein the second part is an elastically more deformable non-metallic material such as plastic.
  • the objective technical object of the present invention is therefore to provide a grinding wheel according to the preamble of claim 1, in which these disadvantages are avoided.
  • the vibration-damping material of the second part is cast iron, preferably with lamellar graphite, spheroidal graphite, vermicular graphite, or cast steel, and / or aluminum bronze.
  • a second part which is made of a vibration-damping material, allows the vibrations generated during the grinding operation to be absorbed efficiently in the carrier body. This suppresses resonance behavior in the area of the natural frequencies. No additional hearing protection is required, even when the grinding wheel is rotating at high speed. Vibration decoupling of the grinding wheel from the rotary drive also takes place, so that vibrations are not transmitted from the grinding wheel to the rotary drive - and vice versa.
  • the vibration decoupling or damping by the second part of the carrier body thus takes place in two directions: on the one hand, the vibrations generated by the grinding surface and, on the other hand, the vibrations caused by the rotary drive or the grinding machine are damped and decoupled from one another.
  • the invention therefore consists not only in providing a carrier body with a vibration-damping material, but in at least two-part construction of the carrier body, one part consisting of a vibration-damping material and the other part being able to be created from a different material, the other, for the grinding insert has favorable physical properties.
  • the first part can be removed again and replaced by a fresh first part, the second part being able to be reused. This is another advantage of the two-part construction of the carrier body compared to the prior art.
  • the vibration-damping material of the second part is cast iron, preferably with lamellar graphite (e.g. GJL 250), spheroidal graphite, vermicular graphite, or cast steel, and / or aluminum bronze.
  • the first part of the carrier body can consist of a vibration-conducting and / or heat-conducting material, preferably steel or aluminum.
  • the abrasive coating be made contactless with the second part, so that vibrations occurring during a grinding process can be indirectly transmitted to the second part via the first part and damped by means of the second part.
  • the first part consists essentially of a fiber-reinforced, preferably carbon-fiber-reinforced, plastic and the second part consists of cast iron.
  • both parts are made of a vibration-damping material.
  • the invention therefore does not necessarily provide that the first part consists of a vibration-conducting material.
  • A, preferably axial, screw connection can be provided for connecting the first and second parts of the carrier body. It is particularly advantageous to provide recesses in the first and / or second part, into which threaded bushings are inserted, preferably glued. In this way, the second part can be recycled in a particularly simple manner. Alternatively, it would also be possible to cut the threads directly into the first and / or second part.
  • the second part has a volume that is approximately twice as large as the first part, and / or that the second part has a higher weight than the first part.
  • This is a very massive second part, which dampens the vibrations arising in the grinding insert in a particularly efficient manner.
  • the illustrated grinding wheel 1 comprises a carrier body which is constructed from a first part 2 and a second part 3 connected to it.
  • the first part 2 consists essentially of steel and is therefore vibration and heat conductive.
  • the first part 2 has a peripheral surface 6 onto which an abrasive coating 7 with a width 12 of approximately 5 mm is sintered. Vibrations and heat generated in the grinding insert can be dissipated via the first part 1.
  • the first part 2 is connected to the second part 3 via two contact surfaces 10 and 11, the axis of rotation 5 being oriented essentially normal to the contact surface 10 and essentially parallel to the contact surface 11.
  • the contact area 10 is many times larger than the contact area 11.
  • the vibrations are forwarded to the second part 3 via these contact areas 10 and 11.
  • This consists of a vibration-damping material, for example cast iron with lamellar graphite or aluminum bronze.
  • the vibrations transmitted by the first part 2 are damped by the vibration-damping properties of the second part 3.
  • the grinding wheel 1 is designed asymmetrically with respect to an imaginary central plane normal to the axis of rotation 5.
  • the second part 3 has a coupling area 4 for connecting the grinding wheel 1 to a rotary drive for rotating the grinding wheel 1 about an axis of rotation 5 running through the coupling area 4.
  • the coupling area 4 is designed as a central bore.
  • the coupling area 4 is thus formed directly in the vibration-damping material of the second part 3, so that the second part 3 functions as a hub.
  • the second part 3 When assembling the grinding wheel 1, the second part 3 is inserted with an approximately cylindrical projection 16 into a corresponding recess 14, which is provided in the first part 2, until the parts 2 and 3 are flush with one another. Then the two parts 2 and 3 are firmly connected.
  • the exemplary embodiment shown is an axial screw connection, that is to say a screw connection parallel to the axis of rotation 5.
  • 3 recesses 9 are arranged in the second part, into which threaded bushings 8 are glued. These are aligned with recesses 15, which are provided in the first part 2.
  • a screw head has space in the recesses 15. After the two parts 2 and 3 have been joined together, they can be firmly connected to one another by screws 13.
  • the first part 2 can be removed again and replaced by a new first part 2, the second part 3 being reusable.
  • the arrangement of the recesses 9 and 15 in the two parts 2 and 3 is only one example of how a screw connection can be realized. A reverse arrangement is also possible. Furthermore, as already stated, the thread can also be cut directly into one of the two parts 2 or 3. And finally, instead of the screw connection, other types of connection - alternatively or additionally - can be used, such as gluing the two parts 2 and 3.
