Definitions

  • the invention relates to a carrier plate and drive plate for lamella grinding wheels with a carrier plate inner part with a receiving bore for a shaft of a prime mover and an outer flange with flange front for aufklebende abrasive blades, the inner part with a Hub is formed, which has an internal thread for the threaded having provided shaft of the prime mover.
  • a carrier plate for lamellar discs with a Drive plate according to the above-mentioned type from EP 0 542 693 A1. There lies the Drive plate flat on the back of the carrier plate, but can because of the hole, which over the thread of the Drive shaft of the prime mover must fit, no exercise centering effect on the carrier plate.
  • carrier plates without drive plate are from the USA-5,951,389 and WO 98 03308 A known. While at the former carrier plate, the hub and the Outer flange are integrally formed and the thread in the hub is formed, the carrier plate according to the second publication a dichotomy, which consists in that the carrier plate has a hub formed separately, which is firmly connected to the carrier plate.
  • both known carrier plates is supported by a shaft shoulder of the Drive shaft on the back of the carrier plate, so that the centering only on the screwed into the hub Threaded part of the drive shaft takes place. This is at the occurring forces during a grinding process not sufficiently, making it a non-round run and Vibrations come.
  • carrier plates for lamella grinding wheels for some time already, made of plastic impregnated fiber material exist and where around the mounting hole around a sheet metal reinforcement is provided.
  • This relatively thin carrier plates are threaded on the Shaft of a prime mover attached and with a nut screwed.
  • the same kind of fastening is also with lamellar grinding wheels before, in which the carrier plate of injected Plastic exist. Also there is only inside a receiving bore provided so that a fastening is necessary on the machine by means of nut.
  • the object of the invention is to provide a carrier plate for lamella grinding wheels the way indicated above, that a quick, yet secure attachment option the lamellar grinding wheels on the drive machine with a good centering of the carrier plate opposite the drive shaft is possible.
  • the hub over the recessed surface of the carrier plate is formed protruding and has a length in the essential to the distance between the surface of the Outer flange and the surface of the recessed inner part equivalent.
  • the internal thread extends over the entire length of the hub extends. It is advantageous if the internal thread has at least two threads.
  • the lamellar grinding wheel shown in section in the drawing 1 has a carrier plate 2, which is a lowered Inner part 3 and an outer flange 4 comprises.
  • a carrier plate 2 which is a lowered Inner part 3 and an outer flange 4 comprises.
  • grinding blades 6 At the flange front 5 of the outer flange are grinding blades 6 in each case partially overlapping shape arranged as for Lamella grinding wheels of this type is typical.
  • the sanding blades 6 are attached by gluing.
  • the lowered inner part 3 has one to the front 3a, i. to the side of the grinding lamellae projecting hub 7 on, with a receiving bore 8 and an internal thread 9 is provided.
  • a stepped recess 11th At the back 10 of the inner part 3 is a stepped recess 11th intended.
  • a drive machine 12 a shaft 13 with external thread 14. Furthermore, on the Shaft 13 a drive plate 15 attached, the drive machines of this kind for the different grinding wheels is provided.
  • Corresponding to Figure 2 is the vane grinding wheel 1 screwed onto the shaft 13, wherein the Internal thread 9 of the hub 7 of the disk grinding wheel 1 with the external thread 14 of the shaft 13 cooperates.
  • the back 10 of the inner part 3 comes to rest against the Drive plate 15, wherein a paragraph 16 of this drive plate engages in the recess 11 of the support plate 2 to a safe centering of the disk grinding wheel 1 on the To secure shaft 13 of the prime mover 12.
  • the hub 7 has a projecting length over the surface 3a of the inner part 3, which corresponds to the distance 17 between the surface 3a of the Inner part 3 and the flange front 5 of the outer flange 4 corresponds.
  • the hub 7 in conjunction with the Wall thickness of the inner part 3 of the carrier plate 2 long enough and provided with enough threads to firmly on the shaft 13 of the drive machine 12 can be screwed.
