Abstract
The utility model discloses an engine rotor pressure ring pouring structure. The engine rotor pressure ring pouring structure comprises a pressure ring, a dead head and a pouring gate, wherein the pressure ring comprises eighteen ribs, a large circumferential plane and a small circumferential plane; middle sections of nine ribs in the eighteen ribs are shaped like arc-shaped bulges and distributed at intervals; and the dead head is placed on the small circumferential plane of the pressure ring. The engine rotor pressure ring pouring structure has the beneficial effects that the engine rotor pressure ring pouring structure can be used for stably lifting the liquid level in a pouring process, so that no turbulent flow phenomenon exists; meanwhile, the structures of middle ribs on the small circumferential plane and the large circumferential plane are changed, so that a feeding channel is smooth, and therefore, the product quality is ensured.
Description
Technical field
The utility model relates to a kind of engine rotor trim ring cast structure.
Background technology
Generator amature is wanted High Rotation Speed, and the trim ring (retaining ring) that is contained in two ends of rotor need to bear great centrifugal force, thereby requires to have high intensity and good plasticity and the minimum comprehensive mechanical properties such as residual stress.For the loss that prevents that the end from causing because of leakage field, produce the efficient of vortes interference generator when preventing from turning round thereby also should have lower permeability.
Traditional pouring type is the pouring type that large plane makes progress, when injecting downwards from the upper surface because of pour steel, molten steel can produce turbulent phenomenon, and the reason because of Cr content higher (3.5-4.5%) in product material composition causes the foundry goods cold shut defects serious simultaneously, thereby causes product rejection.Reason is molten steel is being first by injecting from the big circumference plane, be injected in the small circumference plane by muscle again, slowly be filled to again big circumference plane foundry goods after full Deng small circumference plane foundry goods pouring molten steel, the foundry goods invar water on big circumference plane is always from the big circumference plane to dirty in whole process, and whole plane molten steel can not in time effectively be replenished, it is too of a specified duration that surrounding time differs, while is because of the reason of the easy oxidation of the higher molten steel of Cr, thereby cause a large amount of cold shut crack defect in big circumference plane, thereby make product rejection.
Summary of the invention
The utility model provides a kind of engine rotor trim ring cast structure for above-mentioned the deficiencies in the prior art, can effectively avoid the problems referred to above.
In order to reach above-mentioned technique effect, the utility model adopts following technical scheme: a kind of engine rotor trim ring cast structure, comprise trim ring, rising head, cast gate, described trim ring comprises 18 muscle, big circumference plane, small circumference plane, nine curved convex shape in middle section in described 18 muscle, and spaced apart, described rising head is placed on trim ring small circumference plane.
Described trim ring adopts non-magnetic steel to make.
The beneficial effects of the utility model are: adopt the utility model structure to pour into a mould and can make liquid level stabilizing rising in casting process, there is not turbulent phenomenon, simultaneously due to the change of small circumference plane and big circumference plane intermediate ribs structure, Feeding channel is unimpeded, thereby has guaranteed product quality.
Description of drawings
Fig. 1 is prior art structural representation one;
Fig. 2 is prior art structural representation two;
Fig. 3 is the utility model structural representation one;
Fig. 4 is the utility model structural representation two.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Consult Fig. 1 to Fig. 4, a kind of engine rotor trim ring cast structure, comprise trim ring, rising head 3, cast gate 4, described trim ring comprises 18 muscle 2, big circumference plane 5, small circumference plane 1, nine curved convex shape in middle section in described 18 muscle 2, and spaced apart, described rising head 3 is placed on trim ring small circumference plane 1.
Described trim ring adopts non-magnetic steel to make.
During concrete enforcement, due to small circumference plane 1 to the big circumference plane 5 Feeding channels when carrying out feeding undesirable, therefore the wherein structure of nine muscle in 18 muscle 2 is changed into the shape of muscle shown in Figure 32, increase Feeding channel.5 first water and fullly steadily rise to small circumference plane 1 from muscle 2 again from the big circumference plane during cast, thereby make liquid level steadily increase, there is not turbulent phenomenon, simultaneously liquid level from small circumference plane 1 to big circumference plane 5 uphill process because of the structure change of intermediate ribs 2, Feeding channel is unimpeded, thereby has guaranteed product quality.
Claims (2)
1. an engine rotor trim ring is poured into a mould structure, comprise trim ring, rising head, cast gate, described trim ring comprises 18 muscle, big circumference plane, small circumference plane, it is characterized in that: nine curved convex shape in middle section in described 18 muscle, and spaced apart, described rising head is placed on trim ring small circumference plane.
2. a kind of engine rotor trim ring is poured into a mould structure according to claim 1, it is characterized in that: described trim ring adopts non-magnetic steel to make.
