Definitions

  • the invention relates to a door shaft drive unit of an overhead door with a gear output which can be coupled to the door leaf shaft which is connected to the door leaf by gears and which is connected to the motor output shaft via a multi-stage gear unit comprising a worm gear stage.
  • Gates of the type considered here, in particular industrial gates, work with a shaft via which the door leaf is regularly operated by means of ropes.
  • these shafts can also be used to accommodate a weight compensation device for the door leaf, in particular in the form of a torsion spring device arranged coaxially to the shaft axis.
  • the invention is intended to provide a gate shaft drive unit of the type mentioned at the outset, which can be arranged at the end of a shaft end with a small space requirement and can be connected coaxially to the shaft of the door leaf with regard to its output shaft from the housing receiving the unit; in particular, the requirements of a maintenance operation and a malfunction due to failure of the mains voltage and / or a transmission defect should also be taken into account.
  • a spur gear is arranged in the output force direction
  • a first spur gear is arranged coaxially with the worm gear of the worm gear stage, which meshes with an output-side second gear to which the door leaf shaft can be coupled coaxially, which thereby formed overall gear is mounted in a gear housing, which is designed in the region of the two intermeshing spur gear wheels to reduce the axial space requirement of the output spur gear wheel to a broad-side gear housing wall.
  • the gear output stage made of a spur gear pair enables a particularly narrow design of the gear housing in this gear output area, seen in the axial direction of the gear output shaft.
  • this single-stage gear transmission is laterally arranged in the interior of the housing in relation to its overall extension, as a result of which the output shaft of this transmission stage can be accommodated in a narrower lateral housing part.
  • the coupling flange for the door leaf shaft to be driven can thus be accommodated, in particular in such a way that the gear housing in its Expansion leaf axis direction seen practically does not exceed the space requirement of the flange coupling between the door leaf shaft and the transmission output shaft.
  • Door drives of the type in question must be operable by hand in the event of failure of the drive, in particular the drive motor, for example by interrupting the supplying mains voltage, and in particular have to have an emergency manual drive. It is also important that the gear connection between the motor and the downstream transmission gear on the one hand and the shaft connected to the door leaf on the other hand can be uncoupled in order to be able to move the door leaf without taking the gear and motor in the event of a power supply interruption and the like or gear failure, which in particular also is required for maintenance cases. In this case, the door leaf should move freely in relation to the operator. This should not be associated with the emergency hand chain drive, because it directly replaces the electric motor but otherwise uses the same transmission gear that is provided for the electric motor drive to the door leaf shaft anyway. On the other hand, it must be possible to uncouple the gear connection close to the transition from the gear output side to the door leaf shaft.
  • the essential gear elements are a worm driven by the shaft of the motor, which works together with a worm gear that can be connected to a coaxial gear of a single-stage spur gear via a coupling device.
  • This has an axially displaceable clutch disc, which is non-rotatably seated on a shaft with respect to the driven gear of the single-stage spur gear and which has a corresponding outer circumference connects inner recess of the worm wheel depending on the axial offset position in the engagement or disengagement state.
  • This clutch condition is determined by a lever that can be actuated from outside the gearbox (accessible on the right or left depending on the type of attachment). This acts on a boom, for example, on the nut of the coupling element.
  • the coupling element itself is supported on the housing against the force of a compression spring, so that in principle the coupling state is established and the coupling state is only possible when the boom is rotated in a targeted manner.
  • the boom has an attack arm outside of the housing, which can be locked in various positions - in or out.
  • This locking device is preferably form-fitting and, in particular, practically impossible to operate from the ground and by laypersons.
  • the maintenance specialist has a key which, when inserted into a corresponding configuration of the lever arm, only allows a very specific release of this coupling.
  • another gear is spur-toothed on the motor shaft and engages or disengages with a further gear arranged parallel to it by its displacement, so that it can be engaged and disengaged.
  • This second gear is coupled via a bevel gear to a hand sprocket, which is arranged so that the plane between the two chain runs runs approximately parallel to the wall. If you wanted to arrange the sprocket coaxially to the motor shaft, you needed an additional chain deflection, which is not desirable.
  • the bevel gear also gives the possibility of a simple clutch in this emergency drive train, namely in that the other spur gear meshing with the spur gear arranged coaxially to the motor shaft is axially displaceably mounted and can thus be brought either into engagement with the other gear or outside of this engagement.
  • the advantage of the transmission design according to the invention thus lies in particular in the space saving and with the consequence of avoiding an intermediate transmission link.
  • the drive unit is preferably equipped with a direct current motor which, in a manner known per se, enables a controlled change in speed in such a way that the door leaf can start up gently from the respective end position and can run into the other end position at a decelerating speed.
  • the DC motor is dimensioned such that the drive unit meets a range of requirements which are determined by different door sizes or different door leaf weights and different drive characteristics depending on the area of application, which results in different requirements for torque to be applied on the one hand and rotational speed on the other hand.
  • This drive is therefore not optimally adapted to a specific requirement, which would require a corresponding number of different drive units, but is designed to a certain extent redundantly in order to be able to fulfill a range of different industrial doors and the respective tasks with the same drive.
  • the different torques and / or engine speeds are set exclusively by means of control technology, be it through the respective operating mode-defining modules that can be replaced in the Control circuit be inserted, be it exclusively through different programs for this control.
  • the DC motor can therefore deliver the desired speed and the desired torque, so it is oversized.
  • the maximum requirements are set here as the upper limit for the components with the success that the same drive can be used for all industrial door drives.
  • the only difference is in the control system or the feed devices for the electric motor. Since this is constructed as a direct current motor, this possibility arises in addition to the already existing advantages of the direct current drive.
  • the gear ratio between the motor shaft and the output on the door leaf shaft is preferably about 1: 120.
  • the gear - causing the worm gear here - is self-locking.
  • the door leaf In the event of a power failure, the door leaf can remain somewhere between its target end positions. In such a case, the requirement can be raised that the separation between drive and door leaf shaft cannot be actuated in order to prevent the door leaf from falling out of this position.
  • additional electrical protection can be installed, for example in such a way that the coupling between the worm wheel and the single-stage final transmission cannot be separated if the pin of another moving coil magnet prevents the clutch from being actuated.
  • This magnet is intended to ensure - even when the mains current is not present - that the coupling between the shaft of the door leaf and the output part of the gearbox can only be released when the door leaf is in the closed state, when the door leaf is in the closed state, ie in a state that can no longer fall .
  • the lock can also be lifted in such intermediate positions of the door leaf, ie selectively excite the magnet, and as a result release the clutch.
  • the requirement of these two successive targeted processes represents a deliberate one Proceed safely that can only be carried out by a professional hand and can therefore be held responsible, because it can be assumed that this specialist prevents the door leaf from falling by other means, for example by supporting it in this intermediate layer.
  • Figure 1 shows a section in the approximately vertical plane in the
  • Figure 2 shows a section along the line II - II in Figure 1;
  • Figure 1 shows approximately in vertical section schematically an overall designated 1 gearbox insofar as no value was placed on joints.
  • a housing regularly consists of at least two housing shells, possibly with separate intermediate floors. These manufacturing and assembly aspects of a generally known type are not taken into account in the exemplary embodiment.
  • the sections II - II and III - III according to Figures 2 and 3 illustrate the embodiment and are provided with the same parts with the same reference numerals.
  • FIG. 1 the door leaf shaft 6 and a coupling 7 designed as a flange with the transmission output shaft 28 is shown in phantom.
  • a second gear wheel 3 on the output side of a spur gear pair 2, 3 is arranged in a rotationally fixed and non-displaceable manner, the first gear wheel 2 of which is arranged on a shaft 8 so as to be non-rotatable and displaceable, on which the worm wheel 4 of a worm gear stage 4, 5 is freely rotatable coaxially adjacent is stored.
  • the worm wheel 4 engages A worm gear stage, which is arranged directly on the motor output shaft 9 of a drive motor 10 so as to be non-rotatable and displaceable, or is formed integrally therewith.
  • worm wheel 4 is non-rotatably connected to the first gear wheel 2 via the shaft 8, a torque exerted on the motor output shaft 9 by the motor 10 is thus transmitted via the immediately following worm gear stage to the spur gear pair and from there to the door leaf shaft .
  • a clutch is implemented between the first gear wheel 2 of the spur gear pair 2, 3 and the worm wheel 4 of the worm gear stage 4, 5 in such a way that on the same Shaft 8 for the wheels 2 and 4, another wheel, namely a clutch gear 12 is provided, which is axially displaceably mounted on this shaft 8 against rotation.
