    The present invention relates to a device for a floor processing machine which is movable along a floor and with a number of floor processing tools rotatably driven by a piston motor with coupling between the motor and a saw floor processing tool supporting the axis of the board.
    Problems exist with such machines due to the fact that the vibrations of the motor may undesirably be transferred to the existing coupling which is arranged between the motor and the floor processing tool in question. In particular, there are problems when starting the saw floor processing machine and when driving and hitting harder parts of the floor. . Vibrations from a machine engine that includes pistons can easily unwanted propagate to the machine. There are problems even if the shoulders come into direct contact with each other.
    Known solutions with couplings are difficult to replace and large parts on the machine must first be dismantled before the coupling can be repaired and / or replaced in the event of damage to it.
    The main object of the present invention is therefore i.a. to solve the above problems easily and efficiently.
    Said object is achieved by means of a device which essentially characterizesaccording to the present invention,from the fact that the coupling is formed by an elastic, transverse circumferential direction, slotted heel-shaped coupling ring which is connectable to its respective edge portions with motor shaft and to the shaft of a gear, respectively, said saw coupling ring being openable at its slotted portion forapplication and removal of the coupling ring onl0respectively from connecting portions of the respective saw shafts.
    The invention is described below as a preferred embodiment, reference being made to the accompanying drawings, in whichFig. 1 shows a schematic side view of a single-floor processing machine provided with a device according to the present invention,Fig. 2 shows an enlarged view of the front part of the saw machine with the drive arrangement for machine shown,Fig. 3 shows part of said drive arrangement with couplings for this in perspective obliquely from above,Fig. 4 shows a sectional view of the machineand its driving arrangements,Fig. 5 shows a side view of the drive arrangementmany,Fig. 6 shows a side view of the machine shaft coupling, andFig. 7 shows a cross-section of the saw shaft coupling.
    A device 1 which is located at a floor processing machine 2 of known type, which can be run along a floor 3, and which is provided with a number of cutting and / or grinding floor processing tools rotatably driven by a piston motor 4 with a shaft coupling 5 located between the motor shaft 6 and a shaft 7 starting from a coupling 8 which is arranged to drive a said floor worker.shaft 10 supporting the disc shaft 10, includingsee Fig. 2, takes a shaft coupling 5 of a special kind. More specifically, said shaft coupling 5 is formed by an elastic transverse circumferential direction 40 for the same slotted 9-shaped tire-likenande clutch ring. Said coupling ring is connectable withlOtheir respective edge portions 5A, 5B with the drive shaft 6 of the motor respectively with a said shaft 7 which is connected to said coupling 8.
    The machine 2 shown in Fig. 1 comprises in a known manner a rear-mounted grip and operating handle 11, a stand 12, an internal combustion engine 4, wheels 13, machine housing 14 containing said floor processing tool for grinding and / or polishing of e.g. stone / concrete floor 3, a shaft 10 which carries said tools ona rotating disc (not shown), pulleys 15, 16 for onedrive belt 38 and connected to the shaft 7, which is coupled to the motor shaft 6 with said device 1 and which extends through a centrifugal coupling 8 or other suitable coupling, and the tool plate bearing the shaft 10. At least 15 of said two pulleys 15, 16 are fixed to flange 17 of said centrifugal coupling 8 while the larger 16 of the two pulleys 15, 16 is supported by the tool pulley 16.
    The shaft coupling 5, which is built up of finite rubber bellows, functions so that the motor shaft 6 never comes into direct contact with the said mounted coupling shaft, which means that the motor shaft 6 has a minimal radial / axial influence on the coupling shaft 7 and the machine parts affected therefrom.
    Stable storage of the various parts in the machine 2 is also achieved thanks to the arrangement of lower located bearing box 18, and upper located bearing box 19 and mounting plates 20, 21, 22 for the lower end 7A of the coupling shaft 7, for the upper end 7B of the coupling shaft 7 and 7, respectively. upper end 6A of the motor shaft 6.
    Said rubber bellows is preferably attachable to disc-shaped upper and lower shaft end discs 23, respectively.24 of said shafts 6, 7 and suitably providedfastening by means of bolted joints 25 (schematicshown in Fig. 7). In this case, fixed nuts or threads hollow on the respective two shaft end discs 23, 24 can form abutment bolts from the opposite sides of said shaft end discs.
    Said shaft end discs can either be (not shown) rigidly connected to a shaft 6, 7 emanating from the motor 4 or one from the clutch 8 or as shown in Fig. 7 formed by releasable discs 23, 24 and clamping retaining discs 26, 27 and between which paired discs 23-26 and 23-27 an end portion 28, 29 of the shaft coupling 5 is clampable. With a thickened end portion 28-31, e.g. conically, the clamping of the shaft coupling on the shafts 6, 7 is facilitated. Internally in said abutment discs 26, 27, conical discs or press rings 32, 33 are insertable pre-clamping of said abutment discs 26, 27 on enclosed shafts 6, 7.
    By said abutment discs 26, 27respective pressure rings 32, 33 internally and externally are conical, friction joints 34, 35 are provided betweenthe same and the shafts 6, 7 so that proper, releasable holding is achieved.
    The hollow coupling ring, which is similar to a wheelbarrow wheel, is slotted 9 substantially perpendicularly to the circumferential direction 8 of the coupling ring, whereby said coupling ring can easily be detached from one or both shafts 6, 7 after detachment of the parts 25-33 and pulled away from the two shafts 6, 7 in perpendicular direction. . This can be done without the need to disassemble almost the entire machine 2 as previously had to be done.
    The attachment of* opplingeï 5 is described as follows:lOThe coupling ring can be fastened to said bed-separated shafts 6, 7 by means of a clamping coupling which comprises pairwise conical reading plugs which are readily cooperable with respective disk-shaped reading plates, likewise provided with conical pressure surfaces, the clamping coupling being clampable to respective shaft skis. The shaft coupling is enclosed in an upper space 37, the upper and lower mounting plates 22, 21, respectively, have bushing bushes for each shaft 6, 7 and that the single mounting plate 21 carries bearings for the coupling shaft 7.
    The function and nature of the invention should have been clearly understood from the above and with knowledge even though it is shown in the drawings, but the invention is of course not limited to the embodiments described above and shown in the accompanying drawings. Modifications are possible, in particular as regards the nature of the various parts, or by the use of equivalent techniques, without departing from the scope of the invention.as defined in the claims.
