Definitions
- the invention relates to an electrical machine, in particular a generator for motor vehicles, according to the preamble of the independent claim.
- Axial load in the bearing is disadvantageous, as this may result in an overload and the life of the bearing may be shortened considerably.
- the electrical machine according to the invention with the features of the main claim has the advantage that a large range of spring force characteristics can be achieved with a relatively flat increase in force. This means that beyond the intended compression range of the
- the hub projection has a general ring shape with an outwardly sloping conical spring support surface.
- Spring element essentially has the shape of a truncated cone, a high axial force can be calibrated, so that the rolling elements roll in the rolling bearing under defined conditions on their running surfaces. As a result, the rolling bearing has a favorable service life.
- a spacer is arranged in the effective direction between the bearing and the spring element.
- This spacer like the hub projection provided with an outwardly sloping conical spring support surface, enables an arrangement in the hub without a change of lever for the axially acting spring force.
- the storage is thus able Axial vibrations without absorbing too strong changes in force relatively elastic.
- a spacer is arranged in the effective direction between the spring element and the hub, which fulfills the same purposes.
- the spacer can, for example, be an originally separate ring attached to the spring element, so that overall a cost-effective production of a combination of spring element and spacer is possible.

- Figures 3a and 3b show two views of the spring element from Figure 2a
- Figure 4a and 4b show the behavior of the in a highly schematic view
- FIG. 5a, 5b and 5c show three different views of a second
- Figure 6 shows a third embodiment of a spring element
- FIG. 7 shows a cross section through the fitting sleeve from FIG. 2a.
- FIG. 1 shows a cross section through an electrical machine 10 in a highly schematic view.
- the housing parts 13 and 16 each have a hub 21, which serves to support the shaft 25 of a rotor 27 via a bearing 23 and a bearing 24.
- the left bearing 23 shown in FIG. 1 is a so-called fixed bearing
- the bearing 24 shown in FIG. 1 is a so-called floating bearing. This floating bearing 24 and its design and arrangement in the hub 21 are discussed in more detail in FIG. 2.
- Figure 2a shows the arrangement of the right bearing in a less schematic representation
- the housing part 16 often also referred to as a bearing plate, has in its center the hub 21, which extends axially in the shape of a cylindrical ring.
- a so-called hub projection 30 adjoins the hub 21 and extends radially inward.
- the hub projection 30 is arranged on the side of the hub 21 that faces away from the rotor 27.
- Hub projection 30 has a general ring shape and is formed, among other things, by some spokes 32 oriented in the radial direction.
- An annular spring support surface 35 which is part of the hub projection 30, adjoins the spokes 32 radially further inward.
- the hollow cylindrical hub 21 is a so-called fitting ring 38 is used, which is made of a plastic.
- This fitting ring 38 serves to dampen vibrations between the hub 21 and the shaft 25.
- the shaft 25, which is held in the fitting ring 38 via the bearing 24, projects into the fitting ring 38.
- the bearing 24 is designed in the exemplary embodiment described as a roller bearing, here as
- the ball bearing essentially consists of an inner ring 40, the spherical rolling elements 42 in this case and the outer ring 44.
- the spring element 47 is a plate spring, which in its axial
- the plate spring 47 has essentially the shape of a truncated cone shell and thus a radially inward inner region which is supported on the hub projection 30 or the spring support surface 35.
- the spring element 47 is supported on with an outer region directed radially outwards
- the flat position of the spring element 47 is defined in such a way that the outer region of the spring element 47 then has the same axial position as the inner region of the spring element 47. This is equivalent to the shape of the spring element 47 that is then present, which is approximately a plane.
- An electrical machine 10 is thus provided, in particular in the form of a generator for motor vehicles, which has a rotatably mounted rotor 27, at least one bearing 24 serving to support the rotor 27 in the hub 21 and an axially acting spring force of the spring element on the bearing 24 47 acts.
- the spring element 47 is supported on the hub 21 by means of the spring force.
- the spring element 47 is one
- the spring element 47 is supported in an outer region on the outer ring 44 of the bearing 24 designed as a roller bearing and in an inner region on a hub projection 30.
- FIG. 2b shows a portion of the hub projection 30 or the spring support surface 35 in an enlarged representation. To clarify the shape of the spring support surface 35, this was clearly shown in a greatly exaggerated representation as an outwardly sloping conical spring support surface 35. This strongly conical
- the aim of the spring support surface 35 is that no disproportionately increasing spring force occurs between the hub projection 30 and the outer ring 44 during the axial vibrations of the rotor 27. It is provided that in the extreme position of the spring element 47, ie in a particularly strongly sprung position of the spring element 47 in the direction of the hub projection 30, this spring element 47 does not radially inner edge 53 of the spring support surface 35 comes to rest. Such a strong pushing through of the spring element 47 would mean that the spring force would no longer rest on the radially outward side of the spring support surface 35, but, for example, directly on the edge 53. This would have the consequence that the spring force between the outer ring 44 and the hub projection 30 suddenly would rise and thus possibly the bearing 24 or the spring element 47 would be overloaded.
- the spring element 47 could, in a position pushed through to the boss projection 30, rest against an edge of the bore of the inner ring 40, as a result of which the active lever for the axial force also decreased here and the spring force thereby increased suddenly.
- the spacer 56 has a taper.
- the spacer 56 has essentially the shape of a truncated cone whose larger opening is directed towards the spring element 47.
- the taper is, for example, 7 ° (cone angle 14 °).
- the spacer 56 is thus in contact with the spring element 47 with an essentially narrow annular surface radially on the outside and can also be connected or fastened to the spring element 47 via this annular surface, for example by means of a cohesive connection technique such as welding, soldering or adhesive bonding.
- the spacer 56 avoids a shortening of the active lever in the region of the transition from the spring element 47 to the spacer 56, which would occur with a flat spacer 56 and at the same time a strongly pressed spring element 47.
- the spring element 47 would otherwise rest on the radially inner edge of the spacer 56 directed towards the spring element 47, which increased the load on the spring element. Another reason for this spacer 56 is that the spacer 56 prevents the spring element 47 from resting against the inner ring 40 when the spring element 47 is loaded or pushed through. Otherwise there would be a danger
- a spacer 56 is thus arranged in the effective direction between the bearing 24 and the spring element 47.
- FIG. 3a based on FIG. 2a, a view of the spring element 47 is shown from the left.
- the view of the spring element shown in FIG. 3b is correspondingly 47 is a view from the right.
- the ring shape of the spacer 56 and the spring element 47 can be clearly seen.
- the spring element 47 has an overall wave-shaped inner region.
- a total of three pins 59 are formed on the outer edge of the spacer 56, the function of which is explained below in connection with FIG. 7.
- the number of pins 59 can also vary; for example, four or six pins are also possible.
- Spring support surface 35 lies.
- the axial height of the spring element 47 between the side of the spring element 47 facing the hub projection 30 and the plane of contact is di.
- FIG. 4b shows a spring element 47 which is fully sprung to the right through the flat position, the side of the spring element 47 facing the boss projection 30 now lying beyond the flat position 1 between the outer ring 44 and the spacer 56, U2-It is also clarified that the force F2 now acting between the outer ring 44 and the spring element 47 and between the spring element 47 and the spring support surface 35 has approximately the magnitude of the previously acting force Fj.
- FIG. 5a, 5b and 5c show another embodiment of a spring element 47 in three different views.
- the illustration in FIG. 5a is also a view from the left, accordingly, the view in FIG. 5c is analogous to the illustration in FIG. 3b a view from the right.
- this also has
- Embodiment has a radial inner region which is generally wave-shaped.
- the outer area of the spring element 47 is slotted at short intervals and has alternating radial fitting elements 62, which serve for the concentric positioning of the spring element 47 in the fitting ring 38 and thus also for the concentric positioning to the rotor axis. Alternatively, one immediate concentric positioning between the spring element 47 and the hub 21.
- Spacers 56 are arranged between the fitting elements, which are supported on the outer ring 44 as in the previous exemplary embodiments. These spacers 56 are generally arc-shaped and are angled approximately at right angles.
- Figure 6 shows a third embodiment of a spring element 47. It is provided that the spring element 47 and the spacer 56 to the outer ring 44 are made in one piece. In addition, but also individually applicable, a further spacer 56 is in the effective direction between the spring element 47 and the hub
- the fitting ring 38 is shown in a sectional illustration in FIG.
- the fitting ring 38 has insertion pins 70 at one axial end, which are pushed between the spokes 32 of the housing part 16 and beyond, as also in FIG.
- Figure 2a shown are designed as snap hooks and engage in grooves between the spokes 32. Sections between the pins 70 also interact with the spokes 32 in such a way that the spokes 32 are designed as a stop for the fitting ring 38. The pins 70 limit on the one hand a play of the fitting ring 38 in the axial direction to the left and the gaps between the
- Pin 70 a game to the right, so that overall there is a defined position of the fitting ring 38 in the hub 21.
- three grooves 73 are also formed on the cylindrical inner circumference of the fitting ring 38, into which the pins 59 already mentioned, see also FIGS. 3a and 3b, are inserted, so that there is an overall clear position of the spring element 47 according to the exemplary embodiment from FIG. 2a , 3a and 3b results in the fitting ring 38.
- An incorrect position of the spring element 47 in the hub 21 can thereby be excluded.
- the pins 59 and grooves 73 can also be distributed uniformly over the circumference.
