Definitions
- the present invention relates to a door drive, in particular for garage doors, with a traction mechanism gearbox that is used for Power transmission from a drive motor to the garage door serves, wherein a traction means of the traction mechanism by at least a deflection roller rotatably mounted by means of a roller bearing is led.
- the traction mechanism is a chain.
- Sprocket-trained pulley is one at one end Shaft fixed, the other end rotatably supported in two axially offset ball bearings is added. Between this Bearing section and the sprocket is also on the shaft spur gear provided with a corresponding Gear meshes on an output shaft of a geared motor.
- This arrangement does, on the one hand, relieve the pressure on the Output shaft of the geared motor in the event of tensile loads on the Traction means placed on the sprocket.
- This door drive also has due to the staggered arrangement of two shafts relatively large axial length.
- the one assigned to the drive motor is Deflection pulley fixed directly to its output shaft.
- the output shaft is usually slide-bearing.
- One about the Deflection roller extending portion of the output shaft can also be supported in a ball bearing.
- Tensile loads on this pulley affect directly on the Plain bearing.
- the plain bearing can but also hot running.
- Installation of the door operator complicated. Because the traction device can only after the relative determination of the drive unit and Running track to each other on the ceiling e.g. the garage to the Deflection pulley are threaded, which are assigned to the drive motor is. Then the ends of the traction device are over one to connect a suitable closure. After that the traction device must also be tensioned.
- the rolling bearing is essentially exclusively experiences radial loads, tensile loads by the traction means not to axial force components run the rolling bearing. Because of this, one can be special inexpensive rolling bearings can be used.
- the arrangement can coincide with the center plane of the traction mechanism made of roller bearings and deflection roller particularly flat and therefore space-saving be formed.
- the door drive is shorter than the one mentioned at the beginning well-known gate operator.
- a rolling bearing also a plurality understood by axially arranged individual roller bearings shall be.
- deflection pulley includes Sprockets and pulleys, especially toothed belt pulleys.
- a belt comes as a traction device in the invention however, a positive traction means such as a chain and preferably a timing belt is used.
- the inner ring of the roller bearing on a fixed bearing journal of the door operator fixed.
- bearing journal is opposite protrudes a bottom surface of a holder which laterally in a slide is inserted for a sled that is on the traction device is fixed.
- the measure a separate one, is placed in the side
- the general for storing a pulley of the traction device serves regardless of the type of storage design regarded as a separate invention. This applies in particular to the Holder of the deflection roller, which is assigned to the drive motor.
- This measure has the advantage that the running track can have a uniform profile throughout and therefore, for example. can be extruded. Furthermore, the assembly of the gate operator particularly light. A stable definition of the rolling bearing on the The track of the door operator can only be used with this version two assembly steps can be achieved. First, the holder inserted into the track. Second, the cold turns on the running track.
- the Arrangement thus comprises on at least one side of the running rail a side-inserted cold.
- the corresponding guide roller can either side of the running rail be fixed or via a clamping mechanism.
- the Traction means is wrapped around both pulleys and if necessary tensioned by means of the tensioning mechanism.
- This arrangement can as already mentioned, are delivered pre-assembled and is therefore Particularly suitable for gate drives that are used as a retrofit kit especially for DIY enthusiasts. Due to the Pre-assembly can be excluded that the handyman Traction mechanism gearbox incorrectly installed on the running rail.
- the the only necessary assembly work is the coupling with the garage door on the one hand and with the drive unit on the other.
- the holder can be inserted in any way Have a shape to store any type of pulley. Therefore For example, the same track for different types of Traction devices are used.
- the holder perpendicular to the center plane of the traction device into the running rail e.g. through a correspondingly provided recess
- the holder in the longitudinal direction of the running rail is inserted and at least one flange projection has, which abuts an end face of the running rail and the depth of insertion of the holder into the running rail is limited.
- the holder is approximately parallel to Center plane of the traction device inserted into the track, in usually in an existing longitudinal channel for one Gate drive carriage.
- the positive connection between the running rail and the holder is achieved in that the flange projection lies against the end face of the running rail.
- This measure plays in particular before and during assembly the door drive a role and prevents the Holder accidentally slips out of the track.
- the Holder concentric to the journal one opposite the Bottom surface of the holder protruding boundary wall, the forms an annular channel section together with the deflection roller, through which the form-fitting traction device is guided that a skip of the positive connection in the area of the ring channel section is prevented.
- the holder is made of plastic is made.
- the deflection roller has one Output shaft section for non-positive or positive locking an output shaft of the drive motor, the Output shaft section concentric with the rolling bearing, however axially offset from this is provided.
- the output shaft of the drive motor fixed directly on the pulley.
- this embodiment is advantageous because in this Case bending loads of the output shaft due to tensile loads are excluded by the traction device.
- the plain bearing the output shaft is therefore not loaded.
- the power consumption of the engine can be low due to the low friction be.
- a garage 10 shown in FIG. 1 has a gate 12 locked.
- the gate 12 is designed as a tilting gate and lies with it Top edge on the inside of the lintel 18.
- a motor vehicle 14 is parked in the garage 10.

- the carriage 24 is on a schematically indicated, positive traction mechanism 30 set.
- the traction mechanism 30 has two deflection rollers 32, 33, which act as toothed belt pulleys trained and in end areas of the track 22 are arranged. Around the deflection rollers 32, 33 runs in Fig. 3 toothed belt 36, which is the traction means forms.
- the track 22 and the traction mechanism 30 can be used as one pre-assembled unit can be manufactured and delivered.
- the guide rollers 32, 33 are each mounted on holders that from opposite ends of the track 22 into a channel for the carriage 24 are inserted.
- the traction device 36 runs around the pulleys 32, 33 and is already tensioned.
- On the traction mechanism gear 30 can also already be the carriage 24 must be set. It is for the final assembly of the door drive 20 therefore only necessary, the carriage 24 with the Gate 12 on the one hand and to couple with a drive motor 34.
- the deflection roller 33 is at the rear end of the running rail 22 coupled to the drive motor 34.
- the deflection roller 33 is therefore stored stationary.
- the roller 32 is longitudinally displaceable in the track 22 stored.
- the longitudinal position of the deflection roller 32 is by means of a clamping mechanism, not shown, for the traction means 36 adjustable.
- the track 22 has in Cross section of a U shape.
- the U base is usually on the ceiling 16 set so that the two U-legs of the Stick out blanket 16.
- the running rail 22 has on the outside of the U-leg a longitudinal recess 38. At the ends of the U-legs each have a longitudinal web 40 in front, so that except for one longitudinal gap, unspecified, a closed longitudinal channel is formed for the carriage 24.
- the profile of the longitudinal rail 22 thus formed is above the latter entire length uniform, so that the longitudinal rail 22, for example Extrusion process can be made.
- FIG. 2 runs through one in this Channel laterally inserted holder 42 for the deflection roller 33.
- the holder 42 has a bearing journal which is circular in cross section 44, which is integrally formed with the holder 42 is.
- the bearing pin 44 extends from a bottom surface 58 the holder away from the ceiling 16, such that it is about half the height of the longitudinal channel of the running rail 22 is arranged.
