Definitions
- the invention relates to a dynamoelectric machine, for example an electric generator.
- the invention is particularly concerned with the structural design of a structure by which the winding heads of the rotor are secured against centrifugal forces.
- Such a dynamoelectric machine comprises the following components: a main rotor, annular winding heads, which is arranged axially adjacent to the main rotor and to this coaxial, a support ring, which is arranged radially inside the winding heads and to these coaxially.
- a multiply split ring can be used, which rests with Isolier fundamentallagen on the winding heads and is fixed by means of screws on the bobbin.
- caps can be pushed over the coil heads.
- Such caps are in particular for fixing the winding heads of the rotor turbogenerators usual (Book “Guide of Electrical Engineering” - Volume 3 - “Design and strength calculations of electrical machinery” Author: Dr. C. von Dobbeler, 1962, BG Teubner Verlags Stuttgart, pages 25 to 29 and 58 to 62, DE 26 29 574 B2, DE-PS 7 01 612).
- the safety device against centrifugal forces comprises tension rods, which engage with their radially inner ends on the support ring, and with their radially outer ends of bearing bodies, which rest radially on the outside of the winding heads.
- the winding heads are current-flowed. They are therefore heated to higher temperatures and expand.
- the support ring is not current-carrying and therefore remains cold.
- the air gap between the support ring and the winding heads cooling air is supplied, usually from the front side of the machine. The cooling air enters the radial gap between the winding heads, flows through them in the radial direction and exits outside of the winding heads again. Practice shows that this type of cooling is not enough.
- the invention has for its object to design a dynamoelectric machine according to the preamble of claim 1 such that on the one hand a reliable backup of the winding heads against radial expansion due to the centrifugal forces is ensured, and on the other hand sufficient cooling, the impermissible voltages between the winding heads, the Pull rods and the support ring avoids.
- This object is solved by the features of claim 1.
- the clear widths of the holes in the support ring for passing the tension rods are oversized. Between a tie rod and the reveal of the associated hole in the support ring is thus a tie rod and the reveal of the associated hole in the support ring.
- each tension rod is designed such that the tension rod can perform a limited tilting movement from the radial direction.
- the tension rods run essentially in the radial direction.
- the windings heat up due to the current flow and expand in the axial direction.
- the support ring remains cold and therefore does not expand.
- the tension rods can follow the expansion of the winding heads, since they can take due to the increased clearance of the holes in the support ring an inclination against the radial direction and due to the corresponding design of the bearing body at the radially outward and radially inward end an inclination against the radial direction.
- FIG. 1 shows the basic structure of a dynamoelectric machine in an axially perpendicular section.
- Figure 2 shows an enlarged view of an axial section through the
- FIG. 1 shows a rotor 1 of a dynamoelectric machine.
- the rotor has an outside diameter that can be several meters, for example 5 or 6 meters.
- a hub 2 carries a laminated rotor core 3. This is axially braced by means of a pressure plate 4. Into the grooves of the rotor laminations are Windings 5 inserted. These protrude axially with the winding heads 6 from the rotor laminated core 3.
- the hub extension 2.1 carries another laminated core 7 with plates 7.1 and a pressure plate 7.2.
- the winding heads are further surrounded by an annular support body 8. This consists of several rigid, plate-like ring sections. For clamping the support body 8 and the laminated core 7 of the hub extension 2.1 serve draw bolt. 9
- the embodiment according to the invention according to FIG. 2 comprises a rotor bale 10.
- An annular winding head 60 is arranged axially next to the rotor bale 10. It runs coaxially with the rotor bale 10.
- the machine has an axis of rotation 110.
- Support ring 30 is laminated and serves to support a winding head 60.
- Support ring 30 is provided with ventilation channels 30.1, through which cooling air in the radial direction flows from the inside to the outside.
- Support ring 30 also has radial bores 30.2. Through this tie rods 90 are passed.
- the radial bores 30.1 have over the tie rods 90 excess, that is, the diameter of the tie rods 90 are smaller than the inside diameter of the radial bore 30.2.
- the tie rods clamp the support ring 30 and the winding head 60 together.
- the tie rods 90 abut at their radially outer and at their radially inner ends to corresponding bearing bodies. See the bearing body 80 and 81 and the clamping nuts 70.
- the bearing body allow by a spherical configuration of the respective bearing surfaces, a tilting of the tie rods 90 in an axial plane.
- the tension rods 90 are tiltable due to the described design, that is, they can in the upper region of the bearing body 80 a
- the winding head 60 or its individual parts could be anchored by radial tension rods alone, that is without the tension rods passing through the winding head 60 and at the same time through the support ring 30.
- the winding head 60 could be connected to the support ring 30 by one or more tension rods.
- Such a tension rod could, for example, engage with its radially outer end on the radially inner region of the winding head 60, and with its radially inner region on the radially outer region of the support ring.
- Such a pull rod would have to be variable in length, for example in the form of a telescopic rod.
- a tension spring could fulfill this function.
- Such a tension spring 100 is shown schematically. If such tension springs or rods of the stated type are provided, the tension rods 90 would be dispensed with, and the winding head 60 would have to be clamped together in the radial direction. LIST OF REFERENCE NUMBERS
