Definitions

  • the invention relates to a construction kit with a plurality of Zahnrä- and a plurality of polygonal in cross-section shafts, which are each engageable with the gears, and at least a first and at least one second rotatably connected to a gear hub, wherein the first hub rotatably connected to each shaft is connected and the second hub is not rotatably connected to each shaft.
  • the gears have a central bore of polygonal cross section, which corresponds to the cross section of the polygonal shaft.
  • a gear and a shaft can be positively connected to each other by simply attaching the gear to the shaft.
  • gear and shaft are therefore always connected to each other in a rotationally fixed manner. Turning the gear relative to the shaft is not possible. This severely restricts the possible constructions, since, for example, transmissions in which a toothed wheel as a revolving intermediate wheel mounted on a fixed axis of rotation is not possible.
  • Another known variant provides to form both the waves and the central holes in the gears circular.
  • a rotationally fixed connection is not possible.
  • This element like the gear, has a circular central bore, but if a shaft can pass through this bore, is plugged, are connected by a clamping mechanism with this rotation. At the same time, it engages in the gearwheel which is mounted on the shaft, thus ensuring a rotationally fixed connection between shaft and gearwheel.
  • the disadvantage here is that through the additional component rotatably connected to the shaft gear requires more space than a freewheeling. Therefore, gears with multiple gears and shafts require significantly more space, which limits the number of possible models.
  • the invention has the object to improve a generic construction kit to the effect that even gear arrangements with variable and non-limited translations are space-saving possible.
  • Construction kit characterized in that the axial length of the first and / or second hub corresponds to a multiple of the axial thickness of the gears.
  • both gears are mounted on one and the same hub, also a fixed distance along the shaft between the two gears can be defined.
  • a movement of the gears relative to each other along the shaft can be prevented.
  • both the first hub and the second hub are positively connected to the gears connected. This can be ensured, for example, that the gears have a central bore with a polygonal cross-section and the outer contour of the hubs is adapted to this polygonal cross-section. In this case, the hubs can be easily inserted into the central bore of the gear and thus ensure a rotationally fixed connection.
  • connection between the hub and gear is not as easy to solve, as in a positive connection.
  • flexibility is strongly desired. Children who play with a kit want to take a finished model apart again to make another. For this it is necessary to be able to solve the connection between gear and hub easily and quickly and without additional tools.
  • the first hub has a central bore with a polygonal cross section which corresponds to the cross section of the polygonal waves.
  • a first hub is now rotatably connected to the gear.
  • a polygonal shaft Through the central polygonal hole of the hub can be performed a polygonal shaft. Since the cross section of the central bore and the cross section of the polygonal shaft correspond to one another, a positive connection also engages here. In this case, a non-rotatable connection between polygonal shaft and gear is made. Due to the exclusive use of form-fitting connections, these are also easy to remove without additional tools.
  • the at least one second plug-in hub advantageously has a central circular bore whose diameter corresponds to the diameter of a circumference around the transverse support contour of the polygonal corrugations.
  • no rotationally fixed connection is made by inserting a polygonal shaft in the central circular bore.
  • a rotatably connected to the second hub gear can consequently rotate freely on the shaft.
  • the occupied by the gear piece shaft is not greater than the axial thickness of the gear.
  • the connections between the hubs and the gears can be easily released again and, if necessary, other combinations can be selected.
  • the cross section of the polygonal waves is formed by a plurality of circular arcs of a circle with radius r and the arcs connecting the circular arcs, which are parts of an isosceles triangle.
  • the radius r of the central circular bore of the at least one second plug-in hub corresponds to the radius r of the circular arcs.
  • the gears have different diameters and a different number of teeth. This makes it possible to construct gears of different ratios.
  • the polygonal shafts and / or gears and / or the first and / or the second plug-in hub can be made of plastic or metal, for example.
  • plastic or metal for example.
  • the light weight and simple production of the individual parts speak for themselves, while components made of metal, for example, have greater stability.

  • FIG. 2 shows a polygonal shaft 2.
  • a section through this polygonal shaft 2 along the cutting edge HI-III shown in FIG. 2 is shown in FIG.
  • the cross-sectional profile of the polygonal shaft 2 is formed by three circular arcs 3, which have the same radius r and are part of a circle, as well as by three straight lines 4 connecting these circular arcs, which are part of an isosceles triangle. With dz, the distance defined in FIG. 3 between a straight line 4 and the circular arc 3 opposite it is designated.
  • Figure 4 shows an axial plan view of a first hub 5. It has a hexagonal outer contour 11 over most of its axial length. The distance between each two parallel side edges of this outer contour is denoted by d 2 and corresponds to the distance designated by d2 from Figure 1.
  • d 2 The distance between each two parallel side edges of this outer contour
  • first plug-in hub 5 is therefore form-fitting and thus rotatably inserted into the recess 9 of the gear 1 shown in Figure 1.
  • a stop 10 is provided at one axial end of the first hub 5. This protrudes radially beyond the outer contour 11 and prevents so that the first hub 5 can be inserted through a gear 1 through.
  • the first plug-in hub has a central bore 6.
  • the inner contour of the central bore 6 is formed by three arcs 3, which have the same radius r and are part of a circle and formed by three, these arcs connecting straight line 4, which are part of an isosceles triangle.

  • the distance designated di in FIG. 5 corresponds to the distance from a corner of the outer contour of the first plug-in hub 5 to the corner opposite it and is identical to the distance di from FIG. It can be clearly seen that the stop 10 protrudes beyond the outer contour of the first plug-in hub 5 and therefore can prevent insertion of the first plug-in hub 5 through the central recess 9 of a gear 1.
  • FIG. 6 shows an axial plan view of a second plug-in hub 7.

  • FIG. 7 shows a section through a second plug-in hub 7 along the section line VII - VII shown in FIG.
  • the stop protrudes beyond the outer contour of the second plug-in hub 7, thus preventing the second plug-in hub 7 from being pushed through by the toothed wheel 1.
  • the distance denoted di in FIG. 7 corresponds, as in FIG. 5, to the distance between a corner of FIG Outer contour of the second hub and its opposite corner.
  • the axial length of the second hub 7, which is designated in Figure 7 with 2D, on which it has a hexagonal outer contour 11 corresponds to two axial thicknesses of a gear.
