Definitions
- the present invention relates to a turbine unit - in particular for a Turbocharger, but possibly also for other turbomachines, such as Secondary air pump - which is a rotor housing with at least one supply channel for a Fluid - in the case of applying the invention to a turbocharger, this becomes the exhaust gas an internal combustion engine - and having a turbine rotor, which in a Turbine space of the rotor housing is mounted and the periphery of the fluid over a Guiding variable turbine geometry is supplied.
- Secondary air pump - which is a rotor housing with at least one supply channel for a Fluid - in the case of applying the invention to a turbocharger, this becomes the exhaust gas an internal combustion engine - and having a turbine rotor, which in a Turbine space of the rotor housing is mounted and the periphery of the fluid over a Guiding variable turbine geometry is supplied.
- the baffle has a Blade bearing ring with a variety of on this blade bearing ring in the form of a Wreaths of stored blade shafts and blades attached thereto on one side, each of a substantially tangential position with respect to the rim in a approximately radial position are adjustable, as well as with at least one adjusting element for adjusting the position of the blades. Furthermore, an actuating device for Generating to be transferred to the guide vane with variable turbine geometry Control movements provided via an adjusting ring, the coaxial with the Blade bearing ring and this is adjacent and arranged with the at least one Adjustment is movably connected, and a guide and centering for the adjusting ring, which at least one rolling bearing with on a tread of the Verstellringes running rolling elements comprises.
- the invention is therefore based on the object, a simple and easy to install Construction using (at least) one rolling bearing while maintaining to create its advantages.
- this object is achieved in that the rolling bearing between the Adjusting ring and a releasably connectable to the rotor housing mounting ring is arranged, so that adjusting, rolling and releasably connectable ring as modular unit can be installed in the rotor housing.
- the rolling bearing itself may well be a ball bearing, as will be apparent from the later description. However, it is preferred if that Rolling is designed as a roller bearing.
- the rolling bearing is in an axially open space of one of the rings, Preferably, the adjusting ring is housed, and this clearance by a another ring, in particular axial extensions of the rollers of the rolling bearing retaining ring, is completed.
- the rolling bearing may therefore comprise rollers or balls, which either in sufficient numbers are available in the free space to this essentially or it may be a limited number of at least three reels or balls be guided by a retaining ring in the free space.
- the costs are further reduced and the space required for the installation of the modular Unit reduced when the releasably connectable ring is the blade bearing ring.
- the rolling elements in constant contact with at least one tread it is more advantageous if the cooperating with the rolling bearing diameter of the adjusting ring and the detachably connectable ring are dimensioned such that they are substantially all Operating temperatures allow a radial clearance of the rolling elements.
- This game will be then correspond to each considered tolerable tolerance. "Essentially” means it that in the range of the upper or the lower limit temperature or in the Tolerances may be that this game is suspended and then the Rolling elements on one or the other ring just come to the plant.
- the modular unit in the housing to be fastened by means of screws.
- the modular unit Adjusting ring, roller bearing and releasably connectable ring is rotatably held by interlocking projections and recesses, and is preferably loaded against this situation by a loading arrangement. This further simplifies assembly.
- a snap connection between said projections and depressions are provided.
- the rolling elements between an outer surface of the adjusting ring and the inner surface of a surrounding and releasably provided with the housing connectable ring. This, of course, increases the radial space requirement, which is why it is preferable if the tread of the detachable connectable ring has smaller diameter than the tread of the Adjusting ring.
- the invention also relates to a guide vanes of variable turbine geometry for such turbine units having the features discussed above.
- the turbine housing 2 includes a turbine rotor 4 surrounding supply channel 9 for a turbine rotor 4 driving fluid (in the case of Turbocharger, this is the exhaust gas of an internal combustion engine), a rotor chamber 23 and an axial neck 10, through which the fluid or the exhaust gas is discharged again.
- a turbine rotor 4 driving fluid in the case of Turbocharger, this is the exhaust gas of an internal combustion engine
- This guide grid essentially has a turbine rotor 4 concentrically surrounding ring of movable guide vanes 7 (see Fig. 4), the an with them fixedly connected adjusting shafts 8 in a turbine rotor 4 coaxial surrounding blade bearing ring 6 are mounted.
- the rotation or adjustment of the adjusting shafts 8 can in itself, e.g. from US-A-4,659,295, Known manner done by an actuator Control housing 12, the control movement of a attached to her, only dash-dotted indicated pusher member controls its movement over a Operating lever 13, an associated with this actuating shaft 14 and for example, via an opening in a behind the blade bearing ring. 6 located adjusting ring 5 engaging eccentric 15 in a slight rotational movement this ring 5 is implemented around the axis R. Because in grooves or Recesses 17 (see Fig. 4) of the adjusting ring 5 are the free ends of the lever or Heads 18 are mounted by adjusting levers 19, which are fastened to the adjusting shafts 8.
- the guide vanes 7 are positioned above the shafts 8 their rotational position relative to the turbine rotor 4 adjusted so that it is approximately tangential extending an extreme position in an approximately radially extending other extreme position are adjustable.
- the exhaust gas supplied via the supply channel becomes a Internal combustion engine more or less supplied to the turbine rotor 4, before it at which extends along the axis of rotation R extending axial neck 10 again.
- the adjusting ring 5 has a radial inwardly directed tread 20 on which the rollers 3 can run. This is preferred but only intended for tolerance compensation, because in practice it is preferred if the rollers 3 in substantially all operating conditions both with respect to this Tread 20 and an opposite outer, forming a shoulder Running surface 21 on the blade bearing ring 6 a certain clearance p (Fig. 2).
- Fig. 4 illustrates, only relatively few rollers 3 are required, if this is associated with a cage or retaining ring 22. Although the roles 3 also in Recesses of this retaining ring 22 could run, the rollers 3 have advantageous axial projections 24 of smaller diameter, in the holes 25 of the retaining ring 22nd engage, so that this one hand ensures their distance in the circumferential direction and on the other hand, the rollers and axially fixed on their track against the treads 20 and 21st holds. As will be explained later with reference to FIG.
- Fig. 1 further shows, it would be conceivable that of adjusting ring 5 and blade bearing ring. 6 with all attached parts formed modular unit or cassette also to be provided with a fastening ring 29, which is either on a wall 2 'of Turbine housing 2 can be screwed or, as shown, by means of bolts 30 via Spacer 30a is bolted to the blade bearing ring 6.
- a loading device such as a plate spring 32, which on an inner flange 6 'of the Shovel bearing ring 6 attacks, suffice to hold him in the axial direction and against to press the wall 2 '.
- the other radial end of the plate spring 32 is located on the cylinder piece 40 of the bearing housing. In this case, it is cheap the fastening ring by means of pins 24a non-rotatable but axially movable to store in the turbine housing.
- Fig. 1a shows an alternative solution for a, also as shown in Fig. 1, in Cassette form prefabricated guide grid.
- the rolling elements 3 ' not between Adjusting ring 5 'and blade bearing ring 6' mounted, but between adjusting 5 and another, possibly with a housing part releasably connectable ring 38, and are located on the side facing away from the blade bearing ring 6 'side of the adjusting ring 5'.
- the Cassette can by simple (not shown) solidarization of the ring 38 with the Blade bearing ring 6 'done, such as by screwing or Welding of radially inside and practically adjacent parts 6 "and 38" these two rings 6 'and 38th
- the modular unit 26 (shown in FIG. 1) shown in FIG. 2 has the retaining ring 22 preferably between a radial flange 6 'of the blade bearing ring 6 and a inwardly extending radial flange 5 'of the adjusting ring 5, the so an axial open space 5 "limited, in which the rolling elements 3 are housed
- this interaction of adjusting 5 and - in this Embodiment of the blade bearing ring 6 as a further ring - in reverse Arrangement can be formed by the adjusting ring 5 a the radial flange 6 ' corresponding flange and the blade bearing ring 6 has an axially open Free space 5 "has corresponding axial open space Running surface 21 together with the radial flange 6 'such an axially open space 21, 6 '.
- Fig. 2 illustrates that the adjusting shafts 8 at their the blades 7 facing end may optionally have a reduced diameter, for example, can be used with interference fit in holes of the blades 7.
- FIG. 3 illustrates a slightly modified unit 26 a in a similar section to FIG. 2.
- the changes compared to Fig. 2 relate on the one hand the arrangement of a Sealing ring 27 in a sealing groove 28 of the blade bearing ring 6.
- the blade bearing ring 6 is in the region of a housing wall 2a.
- different sealing arrangements are conceivable: Either is the Sealing ring 27 is formed as a flexible sealing lip extending from below against the Wall 2a lays. This is not a problem in itself, because these two parts in operation yes do not move relative to each other.
- FIG. 1 Another modification of the unit 26a from the unit 26 is that it here with the blades 7 at a defined distance protective mounting ring 29th is provided (see also Fig. 1), which is mounted on the rotor housing on the wall 2 '. Conversely, it is, as can be seen, fastened by means of bolts 30 on the blade bearing ring 6, wherein in a known manner spacers 31 provide for a slightly greater distance, as the width of the blades 7 corresponds to this in their movement in all Temperature ranges not to hinder.
- FIG. 4 is another view of Embodiment of FIG. 3 represents. Because it is both the mounting ring 29 as also to see the seal 27.
- FIG. 5 differs from the previously discussed Variants insofar from, as the sequence of parts in the axial direction vice versa has been. If this possibility explained here only by means of a single example It will be understood, however, that combinations with those described above Modifications and modifications are readily possible.
- the adjusting lever 19 are not on the Blade bearing ring 6 facing away from the adjusting ring 5, but lie, as can be seen, between these two rings 5, 6.
- the adjusting ring 5 can be so be formed, as shown in FIG. 4, but it may also have pins 36 which in Long holes 37 intervene.
- the adjusting ring 5 turn one, radially to inside swept running surface 20 for the rolling elements 3, the other, opposite tread 21 'formed by a separate ring 38 in the Inside the adjusting ring and its tread 20 is housed. In the axial direction then follows again the retaining ring 22.
- a closure ring 39 may be firmly connected to the race 38, for example, by the retaining ring 22 sweeping screws and spacers.
- this end ring plays a role similar to that in Figs. 3 and 4 shown fastening ring on the other side, adding the cohesion of modular unit secures and in one of the ways described with the housing. 2 is connected.
- a sealing groove 28 may be provided in the either a sealing ring 27 (Fig. 3, 4) is inserted or a housing-side sealing ring, which may also be designed as a piston ring, to form a labyrinth seal intervenes.
