Carrier plate for flap discs

Abstract

A carrier plate for flap discs includes an outer flange embodied thereon for securing grinding flaps, and a domed inner partembodied integrally with the outer flange. That part has, for mounting on the external thread of the shaft of a drive machine, a hub having an internal thread, the beginning of whose thread is embodied as a conically outwardly expanded seating surface for a centering projection of an entraining disc, for the bracing of which on the domed inner part of the carrier plate an elastic intermediate element is provided. The elastic intermediate element includes a ring, surrounding the seating surface, that is fixedly connected to the domed inner part.

The invention claimed is: 
     
         1 . A carrier plate for flap discs ( 16 ), having:
 an outer flange ( 20 ) embodied on the carrier plate ( 18 ) for securing grinding flaps ( 22 ) and having a domed inner part ( 26 ), embodied integrally therewith, that has, for mounting on an external thread ( 32 ) of a shaft ( 14 ) of a drive machine ( 12 ), a hub ( 28 ) having an internal thread ( 30 ),   wherein a beginning of the internal thread is configured as a conically outwardly expanded seating surface ( 34 ) for a centering projection ( 36 ) of an entraining disc ( 38 ), for a bracing of which on the domed inner part ( 26 ) of the carrier plate ( 18 ) an elastic intermediate element ( 40 ) is provided, and   wherein the elastic intermediate element ( 40 ) is made up of a ring ( 42 ), surrounding the seating surface ( 34 ), that is fixedly connected to the domed inner part ( 26 ).   
     
     
         2 . The carrier plate according to  claim 1 , wherein a material forming the ring ( 42 ) is overmolded or adhesively bonded onto an outer surface ( 44 ) of the domed inner part ( 26 ). 
     
     
         3 . The carrier plate according to  claim 1 , wherein the ring ( 42 ) comprises cutouts on its circumference. 
     
     
         4 . The carrier plate according to  claim 1 , wherein the ring ( 42 ) is made of plastic.
