According to S ¹ Ig. 1 and 2, the diameter of the housing of the bearing 23 is smaller than the tubular shaft 13 to enable the sockets 27 of the buffing segments 29 and spacers 31 on the shaft 11 to be removed and replaced when the quick-release jaws 19a are open. In the closed state, the jaws 19a secure the housing of the bearing 23 against rocking or vibrating movements relative to the frame 19

As can be seen in FIGS. 1 to 4, the buffing discs' shaft 11 has four outer longitudinal ribs 33 which are equal to each other far away and are welded to the pipe part 13. The outer ones Surfaces 35 of the ribs 33 are curved so that they are for the Displaceability with the inner circumference 37 of the spacers 31 and the inner circumference 39 of the Schwabbell segment mounts 27 match, each having an annular jaw member 28 of U-shaped cross-section in which the buff material collected, as well as held with the help of opposing and inwardly projecting teeth 30 which are in the Buffing disc material are pressed in. ^

Each spacer y \ has subdivided side surfaces 41 and which are in engagement with the adjacent side surfaces 45 of the sockets 27. As can be seen from FIGS. 3 and 4, the spacers 3I have diametrically opposed paired inner lugs 47 ", the adjacent sides 49 of which have longitudinally extending recesses, and the sides 49 are diametrically opposed to one another in pairs on the sides of the ribs 33 spread and wedged in order to prevent a rotary movement of the spacers on the shaft 11.

Each lug 47 has a recess 51 on one side of the spacer 31 and a tongue 53 on the other side, ^so that the recess 51 and the tongue 53 of adjacent spacers form a tightly wedged connection that runs flush with one another in order to enable the preassembly of buffing segments 27 and spacer

holders to facilitate 31, wherein the chocking sides 49 extending in alignment, to accommodate the ribs 33 when the structure is displaced on the shaft 11 · In addition, each projection 47 a portion 55 which eeitenfliehe ζ on the Ansät projecting 41 and an outer surface 57 in order to receive a wobble disk mount 27 in alignment thereon. As shown in Fig. 5, the parts 55 protrude less than the frame 27 is wide, so that the sides of the spacers 51 firmly grip the sides of the buffing wheel frames 27. Preferably, the outer diameter of the spacers 31 is approximately equal to that of the buffing wheel frames 27 by which To secure the grip of the barges 30 on the covering, so that the covering does not engage with the sides of the spacers 31 immediately outside the teeth.

In addition to the tongues 53 protruding in the longitudinal direction, * the lugs 47 inwardly projecting key or button parts 59t for a pre-assembly of wabbels 29 and spacers 31 to ensure, together with an "elastic band 61a, which is stretched over the buttons 59 and on the Keys of the end spacers of the preassembled part is anchored · This together enables the entire structure to be easily moved on the shaft 11, whereby the Surfaces 49 of the lugs 47 are individually wedged onto the corrugated ribs 35 are and interlocking tongues 53 and grooves 51 of adjacent Spacers further prevent the spacers from being displaced while the shaft 11 is being assembled he follows. * ■.

After the buffing group has been assembled, a retaining ring 61 is slid over the housing 23 of the end bearing on the shaft 11. Bayonet fingers 63, which protrude inward from the retaining ring 61, grip the heads 65 of clamping bolts 67 _{1 in} order to securely clamp the floating group on the shaft 11.

As shown in FIGS. 1 and 2, the clamping bolts 67 are secured in the arms 71 of an Annkreuzes 69, which in the Shaft 11 is prevented from rotating in that the Arms. 71 with shoulder edges 73 in the wall 15 of the shaft 11 can be displaced are arranged. The spider 69 stands over a screw thread with the intermediate shaft 75 in connection, which is rotatably mounted, but is held against longitudinal movement in an eager 77, which in and to the wall 13 of the shaft 11 and also in a bore is secured, which is located in the shaft end bearing 25. The end of the intermediate shaft 75 protrudes from the bearing housing 23 and is provided with a hexagonal head 81 to enable that the screw spindle 75 turns "

The structure of the Schwabbeleimrichtüng of segments 29 and spacers 3I arranged between them is secured on the shaft 11 by turning the locking ring 61 by hand, so that the fingers 63 receive the heads 65 of the clamping screws 67, which are arranged on the arms of the arm rim 71 grasp. Then the head 81 of the screw spindle 75 is rotated with a wrench or other tool until the movement of the arm rim 69 has pulled the locking ring 61 sufficiently onto the shaft 11 to securely connect all adjacent buffing disc mounts 27 and spacers 31 with one another and with; the shaft 11 to press · When the Schwabbelsegmente are worn, they can be removed at an early stage after the intermediate shaft is unscrewed 75, the V _ö rriegelungsring has been rotated 61 to the head 65 to bring the Ankerschrmaben and the fingers 63 disengaged and after the jaws 19a behind the periphery of the buffing disc segments 29 are open.

The arranged for the arms of the arm rims 71 in the shaft wall 13- ' Neten openings are also for the transport of air or liquids from the interior of the shaft 11 through the wall 13 to the interior of the structure of the sockets 27 and spacers 31 are provided. Liquid that entrains air or other coolants as well as cleaning agents and liquid mixtures can be regulated from one line

The flow is through the openings in the shaft and through subdivided, radially extending Grooves 87 in the side walls 43 of the spacers led to the outside

The coolant and other liquids are controllable through Each of the spacers is fed and evenly applied to the covering of each of the buffing segments 29 and the circumference of the buffing disk

The coolant flow between the buffing segments 27 closes a residue and build-up of excess heat from

Where the cleaning agent mixture is introduced and through the buffing elements once again penetrates the outside, the buffing disc covering becomes pretreated with the mixture before the surface of the flat buffing elements is subjected to wear. If that Mixture is also applied from the outside, a much more effective appearance of the surface is achieved.
