Definitions

  • Adjustment device for the rotary adjustment of two centrally mounted
  • Adapter pieces especially for a seat, preferably one
  • the invention relates to an adjusting device for the rotary adjustment of two centrally mounted adapter pieces, in particular for a seat, preferably a motor vehicle, according to the preamble of claim 1 and a planetary gear therefor according to the preamble of claim 21.
  • the centrally mounted adapter pieces are fitting tabs which are formed in one piece with a housing part in each case.
  • the adapter pieces consisting of the fitting brackets and the housing parts are deep-drawn parts, the planetary gear with its two internal teeth being located in the deep-drawn area.
  • the two housing parts are fastened to one another by means of so-called holding plates, which have a step shape in cross-section and are designed like a ring segment. These holding plates are each attached to a housing part, overlap a corresponding edge of the other housing part and extend over approximately 90 °.
  • the holding plates serve not only to prevent the two housing parts from falling apart, but also to absorb axial forces acting on the adjusting device.
  • a generic planetary gear is also known, which is designed as an adjustment mechanism for a seat-backrest adjustment.
  • Such a planetary gear enables adjustment at favorable transmission ratios and is subject to extensive self-locking - properties that are common to adjustment mechanisms, e.g. for the listed backrest adjustment, are cheap.
  • a disadvantage of the known adjusting device is that it can diverge at high axial loads and lose its function.
  • the load can be exerted by forces acting axially on the fitting bracket from the outside.
  • the inner, very narrow gears of the planetary gear can be radial are very heavily loaded and then evade. The highest stress results when both types of load occur, namely the axial load from the outside and the radial load from the inside.
  • Another disadvantage of the known adjusting device is that it only allows an adjustment of approximately 180 °. An adjustment beyond 180 ° is not possible because the movable fitting parts then strike the holding plate attached to the other fitting part.
  • a further disadvantage of the known adjusting device is that the adjusting device with its one-piece fitting parts must always be adapted to the respective application, or different adjusting devices with different fitting parts have to be made available for different applications.
  • the adjusting device is constructed in a modular manner.
  • the gears of the planetary gear are housed in a housing. If necessary, the adapter pieces can be attached to this housing.
  • the construction of the housing of the known adjusting device is such that the one housing part has an edge flange and the other housing part has a flanged edge and that the flanged edge is flanged around the edge flange.
  • the disadvantage of this known adjusting device is first of all that different types of housing parts have to be used. Another disadvantage arises from the fact that the housing part having the flanged edge is to be selected from the material in such a way that flanging of the edge is possible in a simple manner. This is disadvantageous in that the rest of the housing must be relatively stiff.
  • the object of the present invention is therefore to provide an adjusting device of the type mentioned at the outset which can be used as universally as possible, also in the case of high loads always maintain their functions and can be easily installed.
  • the invention is also based on the object of further developing generic planetary gear units in such a way that an improvement in function and good manufacturing properties can be achieved with even more favorable tooth engagements.
  • the aforementioned first subtask is essentially achieved in that the two housing parts each have an edge flange and that a separate retaining ring is provided which overlaps the edge flanges and holds the housing parts together.
  • the configuration according to the invention offers a number of advantages, some of which are significant. First of all, in the embodiment according to the invention, it is easily possible to rotate the housing parts relative to one another by 360 ° or more. A striking of one housing part on the other housing part during rotation cannot occur. A gaping apart of the housing parts can also not occur. Due to the transfer of forces to the entire housing, it is also possible to design the housing of the adjusting device overall with smaller wall thicknesses, which in turn results in a considerable weight advantage compared to the known adjusting device.
  • a sufficient seal of the planetary gear or the individual gears of the planetary gear can be achieved by the circumferential retaining ring.
  • the retaining ring not only transmits high forces and seals automatically, it is also very inexpensive to manufacture and easy to assemble.
  • a major advantage of the invention is that a modular unit is provided, to which the necessary adapter pieces are attached if necessary. Compared to the adjusting device known from DE 32 01 309 C2, the fitting tabs or the adapter pieces are no longer formed in one piece with the housing parts.
  • the adjusting device according to the invention can thus be used for the application. In addition to the use of seats in the automotive industry, use of office furniture is also an option. Otherwise, the structural unit according to the invention can be used both for seat back and seat height adjustment.
  • a retaining ring as a separate component has the significant advantage that the housing parts are entirely functional in connection with the arrangement of the planetary gear on the one hand and the absorption of the occurring forces can be designed on the other hand, while the retaining ring must be coordinated with its type of material and the material thickness used exclusively for the holding function.
  • the mounting of the retaining ring can be realized in a particularly simple manner by the retaining ring being flanged over the edge flanges. Flanging of this type can be carried out simply and inexpensively and can easily be integrated into the manufacturing and assembly process. Moreover, when flanging the retaining ring there is no need to fear that one of the housing parts will be affected, as is the case in DE 199 33 895 A1, where one of the housing parts as such has the flanged edge.
  • connection of the adapter pieces to the respective housing parts is of particular importance.
  • a laser weld connection is particularly suitable.
  • Such a welded joint can be made very quickly and can be used well in large series. It is important in this context that laser welding can ensure that there is no "welding through", that is to say gear wheels are also welded, or that there is excessive heat distortion.
  • the edge flanges on the housing parts are formed all around.
  • the housing parts are identical in terms of their outer shape, so that they can be easily assembled.
  • the same boards can be used for both housing parts.
  • the adjusting device according to the invention represents an assembly that is essentially sealed off from the outside Housing through which the occurring radial and axial forces can be safely absorbed. Also, the adjustment device cannot bend over the central axis due to its design, which is disadvantageous for many adjustment devices used in practice.
  • the cup-shaped housing parts can be designed as deep-drawn parts, which can be produced easily and inexpensively.
  • the respective internal toothing can also be easily realized during deep drawing. Deep-drawing the internal toothing results in toothing areas on the outer sides of the housing parts, which are used in the invention. Toothed areas corresponding to the toothed areas are provided on the adapter pieces. When the adapter pieces are attached to the housing parts, the individual teeth of the toothing areas mesh with one another. On the one hand, this facilitates the positioning of the adapter pieces.
  • the positive connection can absorb and transmit forces in the radial or circumferential direction, which in turn has an effect on the aforementioned laser welded connection. In this case, this only has to be designed to absorb axial forces. This idea also has an independent meaning.
  • Planetary gears of the type in question usually have a high degree of self-locking.
  • the device for self-locking has at least one spring means acting on the sun gear and / or a planet gear.
  • the spring means it is expedient for the spring means to be arranged between a housing part and the sun gear or a planet and thus to be part of the structural unit.
  • a disc spring is provided as the spring means, which is very narrow and preferably acts on the sun gear, since the greatest inhibiting effect is achieved here.
  • the spring means is not only used for self-locking, but to even out the movement of the planetary gear.
  • the planetary gear has a certain jaggedness, particularly in the case of straight gears. Due to the spring action, this unsteadiness is hardly noticed by the user.
  • the first internal toothing and the second internal toothing have the same operating pressure angle. This is ultimately achieved in an identical manner, as is the case with the adjusting device known from DE 32 01 309 C2. In this respect, reference is expressly made to this, so that the disclosure in this regard is made the subject of the present application.
  • the planet gears engage in the respective internal gears and / or the sun gear without play.
  • the backlash can be realized in a particularly simple manner in that the sun gear and / or the planet gears and / or the internal toothing are selected by measuring or pairs.
  • the respective toothings of the planetary gear are helical teeth or as arrow teeth. This results in a higher overlap, so that very high forces can be absorbed, which is particularly advantageous if the adjusting device according to the invention is used in places where correspondingly high forces occur. If very high forces do not occur in certain applications, the helical or arrow teeth can still be used, since this not only ensures a high level of safety, but also inferior and therefore less expensive input materials can also be used.
  • the operating pressure angles specified in claim 21 are suitable for solving the second subtask.
  • the gears of the sun gear and / or planet gears and / or the ring gears are particularly advantageous in terms of production technology and are designed as straight gears and are produced without cutting by stamping or embossing when large quantities are produced. In principle, however, helical gearing can also be used.
  • a self-locking friction brake can e.g. be provided in the form of a plate spring.
  • the adjustment means is preferably assigned to the sun gears.
  • the invention makes it possible to use electric motors for the adjustment, which have a very low motor output, since, as has been stated, the forces for adjusting the adjusting device according to the invention are very low.

  • DE 32 01 309 C2 is hereby expressly made the subject of the present application.
  • applications are also possible which are not shown in the aforementioned German patent, for example for adjusting wing flaps in airplanes or in connection with or in office furniture.
  • the adjusting device 2 serves for the rotary adjustment of two centrally mounted adapter pieces 3, 4.

  • the two housing parts 12, 13 each have an edge flange 15, 16 and that a separate retaining ring 17 is provided which overlaps the edge flanges 15, 16 and holds the housing parts 12, 13 together.
  • the retaining ring 17 is designed such that it holds the two housing parts 12, 13 together both in the axial and in the radial direction.
  • the holding ring 17 holding the two housing parts 12, 13 together results in a modular structural unit to which the adapter pieces 3, 4 designed as separate components can be attached.
