Definitions

  • the invention relates to a method for producing a toothing for a Shaft according to the preamble of claim 1, and a door drive, the Gearing is produced using this method.
  • DE 33 45 004 A1 discloses a door closer with a spring arrangement Known in the closing direction actuated shaft, with an operatively connected to this Damping piston and with one end coupled to the shaft pivotable power transmission element as an actuating arm, which has a at the other end, the slider fits into a guide rail. It points the shaft at the shaft ends has a driver with a trained on it Square for non-rotatable connection with the swiveling power transmission element.
  • a disadvantage of such a machined driver with a square at the end of the wave is the increased manufacturing and cost. Therefore for cost reasons, the driver is only made as a square, which means a offset attachment of the power transmission element on the driver only in 90 ° steps is possible.
  • Shafts are also known which are formed at the ends of the driver have machined gears. This makes it possible Force transmission element in finer gradations on the shaft.
  • the disadvantage here is the high manufacturing effort, since the teeth of the toothing be made individually. To ensure high quality is great Accuracy and increased testing effort required.
  • the invention has for its object a cost-effective method with low Manufacturing times for training a driver or a gear high quality for non-positive connection with a power transmission element to develop and a door operator with a shaft with a driver or to form a toothing using this method.
  • Door drives are used to automatically operate doors. This can be electrically operated and sensor-controlled motor drives to be opened and closed, or mechanical drives, in which by manually opening an energy storage device that causes the door to be charged after being walked back into its closed position.
  • door drives are used for this purpose, which are connected via an articulated linkage or via a lever guided in a slide rail by a slide block cause the force to be applied to the door.
  • the door drive on the Frame or be fixed on the door leaf.
  • the lever or the linkage as a force transmission element, based on the arrangement, either on the door leaf or on the frame.
  • floor closers become used, the door operator in the floor area in a so-called cement box is arranged and a lever as a power transmission element acts on the door leaf.
  • the door drives have a shaft for power transmission on which the force transmission element is non-positively via a driver is set. There are also axis extensions to adapt to the Installation conditions applied.
  • the driver is machined and it is usually a square or hexagon formed on it to the cost of the elaborate and lengthy production, for example by milling, does not become too high leave because the surfaces must be processed individually. Resupply failed the shaft or when processing only one of the parts to be manufactured Areas result in a defective part and increased reject rates.
  • gears are used to achieve the shaft. This can cause tolerances be balanced in the door drive, and it can be a preload of the Power transmission element can be set to press the door against to keep the frame in the closed position. Machining is complex and lengthy. It requires very precise processing, because each tooth of the gearing must be manufactured individually. This creates a high possibility of error with the corresponding high reject rates.
  • the production of drivers is possible and high quality gearing possible.
  • the blank can be warmed up be preformed. Subsequent cold hammering gives the shaft then their final shape, with the material beyond its yield point is claimed, which results in an increase in strength and tight manufacturing tolerances results. Due to changes in the material structure, such as the Material compaction, and a refinement of the grain, the material is improved and achieves increased wear resistance. One can by extrusion solidified, particularly clean surface can be achieved.
  • Fig. 1 shows a door closer 1 with a shaft 2 and one connected to the shaft 2 Power transmission element 6.
  • Such door closers can on the Door leaf of a door not shown here can be fixed, the power transmission element 6 designed as a sliding arm and via a sliding block in one can be guided on the frame fixed slide.
  • Door closers are also common 1, in which the power transmission element 6 in two parts via a joint is connected and is fixed to the frame. The reverse is also possible in each case Installation, the door closer 1 is fixed on the frame.
  • the wave 4 can be designed so that the assembly of the force transmission element 6 on Both shaft ends are possible, which means that the door closer on both the left as well as on the right side of the door.
  • the shaft 4 is actuated actuates the force transmission element 6, which is connected to the driver 5 in a rotationally fixed manner, whereby the damper piston 3 moves against the spring assembly 2 and the Spring assembly 2 is tensioned.
  • driver 5 with a square, which in conventional Machined way, for example by milling or shaping are.
  • the driver 5 can also be formed only on one side.
  • FIGS. 4a and 4b show a method according to claim 1 manufactured teeth 8 shown, the teeth 8 on the end face End of the shaft 4 is formed on the driver 5.
  • the toothing 8 is there partially formed on the end face and on the outer surface of the shaft 4. It is also conceivable to form a toothing 8, which only on the lateral surface of the shaft 4 is formed.
  • Figures 5a and 5b show a further embodiment of a toothing 8 ', which is produced by the method according to claim 1.
  • the toothing is 8 ' formed on the end face of the shaft 4.
  • the driver 5 or the teeth 8, 8 'or both by reshaping can be made.
  • the production by reshaping the driver 5 or the teeth 8, 8 'fixed on the carrier 5 can be pulled or pressed or embossing or from a blank by cold or warm hitting.
  • a sequence of these methods can also be used.
  • Cold or The blank can also be pre-shaped by hot-stamping and then get its final shape by cold beating.
  • this is in the material structure Grain refined and the material compacted and thus the material improved, so that there is high wear resistance.
  • a solidified, particularly clean surface can be achieved.
  • Others are also possible Forming methods such as explosive or magnetic forming processes because of the forming speed the material properties can be further improved.
  • toothing 8, 8 ' produced by a forming process in addition to straight toothing 8, 8 'also other types of toothing, for example with varied flank angles or helical gears.
