SU1537500A2 - Buffing grinding wheel with flaps - Google Patents

Abstract

The invention relates to abrasive tools with flexible elements used to treat the surfaces of parts in various industries. The purpose of the invention is to simplify the design. The wheel hub consists of three discs 1 with peripheral through axial grooves 3 for accommodating petal packs. On the inner surface of the discs, protrusions 4 are made in the form of pins pressed into radial holes 5. Disks 1 are mounted with a gap on sleeve 6. On the outer surface of sleeve 6, for example, four helical grooves 7 are made with the same helix angle: two of them are right directions and two left. In these grooves 7, protrusions 4 are placed. The clamping of the petal packs is performed as follows: one of the nuts 10 is unscrewed, then the other is tightened, moving as it is screwed along the sleeve 6, and moves the disks 1. With axial movement, the disks 1 simultaneously rotate around their axis. Since the outer discs of the protrusions 4 enter into the grooves 7 of one direction, and the middle one - of the opposite direction, as they move axially, they turn towards each other, clamping the packets of petals. 6 Il.
