Definitions

  • the invention relates to a drive unit for an automatic revolving door according to the preamble of claim 1 and claim 2.
  • Centrally driven automatic revolving doors are usually constructed in such a way that the output shaft of the drive unit drives the part of the revolving door rotating around the central axis via a transmission element such as a chain, toothed belt or similar.
  • a transmission element such as a chain, toothed belt or similar.
  • the output shaft of the drive unit and the part of the revolving door rotating about the central axis are mounted separately.
  • the pamphlet DE 93 19 807 U1 describes such a centrally driven automatic revolving door of the usual design, in which the drive unit drives the part of the revolving door rotating about the central axis via a transmission element.
  • the drive train consists of an electric motor, gearbox, gearbox output wheel, transmission element and carousel drive wheel, with the gearbox in turn being made up of various individual parts. Because of the gear reduction, the electric motor rotates at a relatively high speed, which causes noise. Noise is also caused by the gear itself.
  • the height of the drive unit is made up of the height of the motor/gear unit and the width of the gear output wheel.
  • the central column With a length of e.g. 280 cm, the central column has an axial length expansion range of +/- 5 mm. Without compensation for the play in length expansion, there is a risk of mechanical stresses in the system and a resulting impermissible axial load on the pivot bearing, which leads to premature wear.
  • the DE 10 2013 000 421 A1 provides two deep groove ball bearings arranged at a distance from each other and aligned perpendicular to each other to compensate for the expansion play. This does not compensate for the length expansion play, but only increases the load capacity of the bearing in the axial and radial directions.
  • the DE 197 34 398 B4 uses a radially outward slewing ring on which the rollers of the center column roll.
  • this has the disadvantage of a complex construction with a large diameter, and if the center column is extended in length, the slewing ring only insufficiently supports the ceiling-side bearing of the center column.
  • the invention is therefore based on the object of developing a drive unit for an automatic revolving door of the type mentioned at the outset in such a way that an axial length expansion play of the center column can be accommodated favorably by the bearing of the center column near the ceiling with little construction effort and little wear.
  • the invention is characterized by the technical teaching of claims 1 and 2 in order to solve the task at hand.
  • a feature of the invention is that the ceiling-side bearing of the center column is designed to be displaceable in the axial direction or that the center column is designed to be displaceable with respect to the bearing near the ceiling.
  • the bearing point in the drive unit is designed in such a way that the rotating part of the revolving door can be displaced in relation to the fixed part of the drive unit in the direction of the central axis, thus ensuring that this bearing point acts as a movable bearing for the bearing of the part of the revolving door can serve.
  • the bearing point below the rotating part of the revolving door which also bears the weight of the rotating part of the revolving door, can be designed as a fixed bearing for the storage of the rotating part of the revolving door. This ensures that the system is not overdetermined. This is important so that the system continues to function with little wear and tear even in the event of deformations, which can be thermally induced, for example.
  • the ceiling-side bearing of the center column consists of just a single deep groove ball bearing, which absorbs the forces acting in the radial direction and whose inner bearing ring can be displaced on a vertically aligned extension of the rotating part of the drive unit is stored.
  • roller bearing instead of a deep groove ball bearing another roller bearing is used, such as. B. a cylindrical roller bearing, barrel roller bearing or spherical roller bearing. All of these roller bearings can be designed in one or more rows. Furthermore, a double-row angular contact ball bearing could also be used.
  • the inner bearing ring is not immovably connected to the vertical extension of the rotating part of the drive unit, but is axially displaceable on it.
  • a reduction in the overall height of the drive unit also results from the following additional feature: Due to the fact that the electric motor in the drive unit is designed as a high-pole, permanent magnet-excited synchronous motor with concentrated windings, there is the advantage of significantly smaller winding overhangs compared to conventional distributed windings. This ultimately results in a smaller height of the drive unit and less heating.
  • concentrated windings is understood to mean that on the stator side there are slot teeth which are distributed uniformly around the circumference and are arranged at a mutual distance from one another, each carrying a single stator winding (concentrated on the slot tooth).
  • the position sensor for commutation of the electric motor in the drive unit is designed as a sine/cosine sensor with a number of periods per revolution corresponding to the number of pole pairs of the electric motor, the commutation of the electric motor can be easily accomplished.
  • the position encoder also has a sine/cosine track with one period per revolution, the position of the part of the revolving door rotating about the central axis is also known at all times.
  • a braking device which can take over the braking of the rotating part of the revolving door in whole or in part, is integrated into the drive unit, it can be ensured that, in the event of an emergency stop, the braking effect is greater than could be achieved with the electric motor alone can be. Furthermore, this results in redundancy with regard to braking the rotating part of the revolving door, in that both the electric motor and the braking device can be used for this purpose.
  • a locking device with which the rotary movement of the rotating part of the revolving door can be blocked, is integrated in the drive unit, the rotary movement can be blocked without an additional device outside the drive unit.
  • the inner bearing ring can also be immovably connected to the vertical extension of the rotating part of the drive unit.
  • the inner bearing ring can move in the axial direction of the center column relative to the outer bearing ring of the slide bearing and absorbs the considerable play in length expansion in the range of up to +/- 5 mm of the center column.
  • roller bearing is used, the roller bearing being immovable and fixed and on the vertical leg of the rotating part of the Drive unit is coupled.
  • the roller bearings used with it are therefore designed to be axially non-displaceable and only the accommodation of the center column on the bearing arrangement absorbs the axial displacement forces.
  • the cover-side receptacle of the center column consists of two toothed cylinder sleeves which are inserted into one another in radial toothing engagement and are designed to be axially displaceable with respect to one another.
  • One, inner cylinder sleeve is non-rotatably connected to the outer circumference of the center column and carries a radially outer toothing aligned in the axial direction, which is distributed evenly around the circumference.
  • the inner cylinder sleeve which is rigidly connected to the central column, participates in the axial expansion play of the central column and slides along the toothing in relation to the opposite outer cylinder sleeve, which in turn is rigidly connected to the rotating part of the drive unit.
  • the toothed engagement of the two cylinder sleeves thus takes over the axial expansion play of the center column, so that the roller bearings used can be arranged torque-proof and immovably on the rotating part of the drive unit.
  • bearing unit is arranged directly on the center column and can absorb the axial expansion play of the center column either directly or indirectly.
  • the two passage openings and the two drum walls 5 are arranged on a circle.
  • the two passage openings and the two drum walls 5 each occupy a quadrant.
  • the four mutually perpendicular door leaves 4 are attached to a center column 3 located in the center of the circle.
  • the center column 3 is rotatably mounted by means of the drive unit 1 and the bearing point 2 attached to the floor 6 below the rotating part of the revolving door.
  • the drive unit 1 shows a central vertical cross-section through the drive unit 1.
  • the drive unit 1 consists of a stationary part 8 and a rotating part 9.
  • the stationary part 8 of the drive unit 1 is attached to the ceiling 7.
  • the drive unit 1 includes a bearing 10 which is connected to the stationary part 8 of the drive unit 1 via a tight fit and to the rotating part 9 of the drive unit 1 via a loose fit. This bearing point is therefore suitable for taking on the function of the floating bearing for the storage of the rotating part of the revolving door.
  • the center column 3 is rigidly connected to the rotating part 9 of the drive unit 1 by means of a device 12 in such a way that the torque that occurs can be transmitted.
  • the drive unit 1 also includes an electric motor designed as a high-pole permanent-magnet synchronous motor with concentrated windings, a position sensor designed as a sine/cosine encoder, a braking device 18 and a locking device 20.
  • the high-pole permanent-magnet synchronous motor with concentrated windings consists of the stationary part 8 stator teeth 13 connected to the drive unit 1 and windings 14 wound around them and permanent magnets 15 mounted on the rotating part 9 of the drive unit 1.
  • the sine/cosine encoder consists of a reading device 16 connected to the fixed part 8 of the drive unit 1 and one on the rotating part 9 of the drive unit 1 mounted track 17.
  • the braking device 18 is connected to the fixed part 8 of the drive unit 1 and acts on the brake pad 19 on the rotating part 9 of the drive unit 1 for braking.
  • the locking device 20 is connected to the stationary part 8 of the drive unit 1 .
  • the plunger 21 of the locking device 20 is pressed into one of the slots 21 provided on the rotating part 9 of the drive unit 1 .
  • FIG. 2 Compared to the embodiment in FIG. 2, further details of the construction are shown in FIG.
  • the rotating part 9 of the drive unit consists of an approximately plate-shaped base disk 9a which is oriented horizontally and which, at its radially outer end, concentrically carries a projection 9b which is oriented vertically.
  • a vertically aligned projection 9c is arranged concentrically approximately in the central region, and near the center column 3 another vertically aligned projection 9d is provided concentrically.
  • the fixed part 8 of the drive unit consists of an approximately plate-shaped base disk 8a, on the radially outer end of which the projection 8b and radially inwardly the projection 8d are formed.
  • the two disk-shaped parts 8 and 9 with the approaches 8b, 8d and 9b-9d shown are therefore one inside the other.
  • the device 12 for connecting the center column 3 to the rotating part 9 of the drive unit consists of the base body 44 with a conical bore and the tapered sleeve 45. These are braced against one another, resulting in a rigid connection between the center column 3 and the rotating part 9 of the drive unit .
  • the bracing is done with the help of clamping screws 43, the head of which is supported on the cone sleeve 45 and which are screwed into the base body 44.
  • FIG. 3 now shows that the deep groove ball bearing 10 shown there is loosely seated in that the inner bearing ring 25 is arranged in an axially displaceable manner on the outer circumference of the extension 9d.
  • the bearing ring 25 is mounted in the area of a displacement surface 27 in an axially displaceable manner with the inner, vertical extension 9d.
  • the outer bearing ring 26 lies opposite the inner bearing ring 25 .
  • the outer bearing ring 26 rests on a circlip 34 placed on the fixed lug 8d of the stationary part of the drive unit, while a similar circlip 33 is placed on the upper end of the vertical lug 9d to limit displacement of the inner bearing ring in the axial direction.
  • center column 3 rotates in the directions of the arrows 28 and is driven in rotation.
  • FIG. 4 shows, as a further exemplary embodiment not according to the invention, that instead of a roller bearing, as has been described in the general part, a plain bearing 30 can also be used, as illustrated in FIG.
  • the inner bearing ring 35 can be displaced in the axial direction compared to the outer bearing ring 36 and thus has an axial bearing play 32 .
  • the two bearing rings 35, 36 are separated from one another in a manner known per se by a bearing gap 31, which can also be lubricated.
  • the inner bearing ring 35 is thus immovably connected with a tight fit 29 to the outer circumference of the vertical shoulder 9d.
  • FIG. 5 shows, as a further exemplary embodiment not according to the invention, that the axial play of movement of the center column 3 acting in the directions of the arrow 42 can also be absorbed by two cylinder sleeves 37, 38 connected to one another via toothing.
  • the inner cylinder sleeve 38 is non-rotatably connected with its inner circumference to the outer circumference of the center column 3 and has teeth 39 aligned in the longitudinal direction on its outer circumference.
  • the complementary toothing 41 of an outer cylinder sleeve 37 engages in this toothing 39 .
  • the two cylinder sleeves can thus be displaced axially with respect to one another via their meshing teeth 39 , 41 , but can transmit the torque to the center column 3 .
