Definitions
- the invention relates to an electric drive device for a vertically adjustable wall panel.
- a shaft has been installed above the side Eüh_rangsbalken, which guarantees the synchronism of both ropes or chains attached to the sides of the wall panel.
- Patent specification 600.832 describes a drive device with two hydraulic motors connected in parallel. In the case of drives with electric motors, use has been made of the possibility of a so-called electric shaft.
- the object of the invention is to carry out the drive with two simple electric motors without an electric shaft, in particular the installation in the lateral guide bar should be possible.
- the invention solves this problem with a drive device, which is characterized in that an electric motor with worm gear, a driven pulley and a slip clutch are combined to form a unit which can be installed in the hollow guide bar, for which purpose the motor is arranged vertically and has a hollow shaft through which the drive cable is passed.
- slip clutch is designed so that it can release the driven pulley at least during assembly. This then allows the weight of the blackboard to be tared exactly to the weight of the two counterweights.
- Fig. 1 shows the drive device in the installed position, partly in section
- the guide bar F in the upper area of which is never accommodated, is indicated by thick dash lines.
- the driven rope wheel protrudes a little from the beam, it has a recess at least in this area.
- the motor housing 10 is expanded in its upper area, so that a worm gear 20 can be accommodated therein.
- the worm 21 is mounted on the hollow shaft 31 of the electric motor 30.
- the worm wheel 22 is fastened on a shaft 23 which is guided outwards through the housing 10 on one side.
- the hollow shaft 31 of the motor 30 is rotatably supported at the top and bottom in the housing in ball bearings 32.
- a fixed (not rotating) guide tube 12 is fastened in the cover caps 11 for these bearings.
- a rope S is passed through the tube 12.
- One end of the rope is connected to a counterweight, not shown, attached in the guide bar.
- the other end of the rope S is attached to the blackboard, also not shown.
- the rope is guided over the rope pulley 40.
- the pulley 40 is driven by a toothed wheel 24 fastened on the shaft 23 with the aid of a toothed belt 25.
- a toothed wheel 26 is mounted on the shaft 41, on which the rope pulley 40 is also mounted.
- the shaft 41 is rotatably supported in the bearing plates 13, 14, which are connected to the housing 10.
- the bearing plate 13 is fixed, the plate 14 releasably connected to the housing 10.
- the shaft 41 with the parts attached to it is shown on a larger scale in FIG.
- the toothed wheel 26 and a disk 42 provided with a brake lining 46 are fixedly arranged.
- a collar 43 and an insertion wedge 44 are used for this purpose.
- the cable pulley 40 is rotatably and axially displaceably mounted on the shaft 41.
- the pulley 40 is provided with a slide bearing bush made of self-lubricating bronze. You could also be provided with a needle bearing since the required axial displacement is only very small.
- the right side of the rope pulley 40 rests on the brake lining 46.
- three resilient plate disks 45 are attached, which are supported against a two-part counter pressure disk 60.
- the counter pressure plate is designed in two parts so that it
- the two-part counter pressure disk 60 comprises a disk 61 fixedly attached to the shaft 41 and a disk 61 which is rotatable and slightly axially on the shaft 41. sliding loose washer 62.
- the washer 61 is provided with an internal thread and screwed onto the thread 47 of the shaft 41 for the purpose of adjusting the pressure and fixed in the correct setting position by means of the adjusting screw 63 (see also FIG. 4).
- the two disks 61, 62 there are recesses 64, 65 on the opposite sides, in each of which there is a hardened ball 66.
- the depressions 64 in the disk 61 are deeper than those in the disk 62, so that the balls in the disk 61 are held therein by their largest diameter.
- the plate springs are relieved and the cable pulley 40 can rotate freely on the shaft 41.
- the disk 62 is now rotated against the disk 61, the balls 66 come to rest on the surface of the disk 62 next to the depressions 65.
- the distance between the disks 61, 62 increases, the springs 45 are tensioned and the cable pulley 40 is in contact with the brake material 46 of the disk 42 with corresponding pressure.
- Such a drive is installed in both guide columns E on both sides of the blackboard.
- Three-phase motors with short-circuit armatures are advantageously used as motors, which are switched on by contactors for either clockwise or counterclockwise rotation. It has been shown that you can get by without an electrical wave.
- the blackboard is additionally provided with a parallel guide that is forced by ropes and rollers. Minor synchronization errors of the motors are compensated for by this parallel guidance in combination with the slip clutches.
