Description
Technical Field
The utility model belongs to the clamping ring field, concretely relates to rotor clamping ring that engine was used.
Background art:
the clamping ring is one of key part sleeves of the steam turbine device, the reliability of the clamping ring is important to the unit operation safety, along with the continuous improvement of the green low-carbon development and the energy structure upgrading requirement, the nation also increases the research strength of the steam turbine with higher parameters, and as the key part sleeve of the steam turbine device, the rotor clamping ring is also one of very important parts
Because the characteristics of clamping ring, it is very important to fix, but often with the screw fixation, can make the clamping ring life-span very short, often just need change after a period of time, it is very troublesome, again because be large-scale machinery, it is also very complicated to change, consumes manpower and materials very much. The cost is also increased most.
The invention content is as follows:
the utility model aims at having the above-mentioned problem to current technique, provided a rotor clamping ring that the installation of being convenient for, simple structure, convenient to use's an engine was used. The purpose of the invention is achieved by the following technical scheme: a large stator pressing ring comprises a circular pressing ring body with a shaft hole in the middle, wherein the pressing ring body comprises an upper pressing ring and a lower pressing ring, the upper pressing ring and the lower pressing ring are connected through at least 4 connecting blocks, the upper pressing ring is placed in the center of the lower pressing ring, a first connecting through hole is formed in the upper surface of the upper pressing ring and is arranged between the two connecting blocks, a plurality of second connecting through holes are formed in the lower pressing ring,
preferably, the method comprises the following steps: 12 groups of first connecting through holes are arranged on the upper surface of the upper pressing ring, each two rows of vertically arranged through holes form a group, and each row is at least provided with an upper through hole and a lower through hole.
Preferably, the method comprises the following steps: the connecting block is a reinforcing rib of a trapezoidal structure, the reinforcing rib is welded at the bottom of the upper pressing ring and on the surface of the upper pressing ring, the length of one side edge of the reinforcing rib of the trapezoidal structure is larger than that of the other side edge of the reinforcing rib, and two bent buffering arc surfaces are arranged at the joint of the connecting edges of the two sides and the upper pressing ring.
The utility model overcomes prior art's is not enough, has done an improvement to the rotor clamping ring, goes up clamping ring one side-mounting one, and it is more convenient to work through changing the clamping ring, the utility model discloses still have simple to operate, convenient to use, characteristics such as easy operation.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of fig. 1 from direction a-a.
Detailed Description
The invention will be described in detail below with reference to the following figures: as described in FIGS. 1-2: a large stator pressing ring comprises a circular pressing ring body 1 with a shaft hole in the middle, wherein the pressing ring body 1 is composed of an upper pressing ring 2 and a lower pressing ring 3, the upper pressing ring 2 is connected with the lower pressing ring 3 through at least 4 connecting blocks 4, the upper pressing ring 2 is placed at the central position of the lower pressing ring 3, a first connecting through hole 5 is formed in the upper surface of the upper pressing ring 2, the first connecting through hole 5 is formed between the two connecting blocks 4, a plurality of second connecting through holes 6 are formed in the lower pressing ring 3, 12 groups of first connecting through holes 5 are formed in the upper surface of the upper pressing ring 2, each two rows of vertically arranged through holes form one group, at least two upper and lower through holes are formed in each row, the connecting blocks 5 are reinforcing ribs of a trapezoidal structure, the bottom of the upper pressing ring 2 and the surface of the upper pressing ring 3 are welded, one side edge 7 of each reinforcing rib of the trapezoidal structure is longer than the other side edge 8, and two bent buffer cambered surfaces 9 are arranged at the joints of the connecting edges at the two sides and the upper pressing ring.
The utility model overcomes prior art's is not enough, done the modification to the clamping ring, add the clamping ring on the basis of original clamping ring, the clamping ring is used basically to fixed, let the rate of utilization greatly reduced of clamping ring, and two clamping rings are through the combination of two upper and lower strengthening ribs, let the clamping ring body more fixed, and the strengthening rib passes through on one side with the opposite side, make a side atress that length is big less, end limit one side atress is big on the other side, because one side of minor face is the shaft hole, so think this method for the protection. The stress is more uniform, and the use and the operation are simpler and more convenient.
