Abstract
The utility model discloses a kind of impeller sleeve riveting set of impeller technical field, including mid-game, drift is installed at the middle disk center, the drift is at middle disk center, axle sleeve is installed at the top of the mid-game, inner chamber is provided with mounting hole in the axle sleeve, and the mounting hole site is in drift bottom.The utility model use turn over riveting structure technology with respect to screw structural for, improve production efficiency, save man-hour, reduction manufacturing expense, both sides workpiece can be made tightly to be bonded firmly.Product quality is stable, then coordinates welding procedure, makes axle sleeve and the increase of the torque value of mid-game, improves the overall performance of wind wheel.
Description
Technical field
Impeller technical field is the utility model is related to, specially a kind of impeller sleeve riveting set.
Background technology
Impeller had both referred to the wheel disc equipped with movable vane, was the part of impulse turbine rotor, again can be with finger wheel disk and peace
The general name of the moving blade of dress thereon.Turbomachine occupies highly important in the especially whole heavy industry system of national economy
Status.Wherein gas turbine has been widely used for moving as the core of the high-end fields such as aviation, power station, naval vessel, tank, heavy loading locomotive
The main or auxiliary power in the general industry such as power and metallurgy, exploration, chemical industry, building field, thus there is increasing people to recognize
For the level of production of gas turbine turns into one of most important mark for weighing a National Industrial overall strength.And steam turbine
Achievable single-machine capacity is bigger, rotating speed is higher, and reliable, fuel cost is low, technology relative maturity, thus as center
Play the role of in terms of the active force of power station and large ship and warship irreplaceable.Higher reliability also makes steam turbine in smelting
The industrial application such as gold and chemical industry is more universal compared with combustion engine.Impeller axle is part important on impeller again, traditional wind wheel
Mid-game and axle sleeve are that production efficiency is not high on screw structural, man-hour length, and manufacturing expense is higher, it is impossible to both sides workpiece is tightly pasted
Close firm.
Utility model content
The purpose of this utility model is to provide a kind of impeller sleeve riveting set, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of impeller sleeve riveting set, including mid-game,
Drift is installed, the drift is provided with axle sleeve, the axle at middle disk center at the top of the mid-game at the middle disk center
Inner chamber is provided with mounting hole in set, and the mounting hole site is in drift bottom.
Preferably, the mid-game is to turn over riveting edge pressing structure with axle sleeve junction.
Preferably, the middle panel surface is provided with several and hole is fixedly mounted.
Preferably, the drift is cylindrical structural.
Compared with prior art, the beneficial effects of the utility model are：What the utility model used turns over riveting structure technology phase
For screw structural, improve production efficiency, save man-hour, reduce manufacturing expense, both sides workpiece can be made tightly to be bonded firmly.Production
Quality is stable, then coordinates welding procedure, makes axle sleeve and the increase of the torque value of mid-game, improves the overall performance of wind wheel.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1 mid-game, 2 drifts, 3 axle sleeves, 4 mounting holes.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of impeller sleeve riveting set, including mid-game 1, it is described
Drift 2 is installed, for the drift 2 at the center of mid-game 1, the top of mid-game 1 is provided with axle sleeve 3, described at the center of mid-game 1
Inner chamber is provided with mounting hole 4 in axle sleeve 3, and the mounting hole 4 is located at the bottom of drift 2.
Wherein, with the junction of axle sleeve 3 to turn over riveting edge pressing structure, the mid-game 1 of wind wheel and axle sleeve 3 turn over riveting side for the mid-game 1
Structure, it is the technological innovation technique on traditional screw structural.The surface of mid-game 1 is provided with several and hole is fixedly mounted,
It is easy to the installation of impeller axle, the drift 2 is cylindrical structural, mutually agrees with motor shaft, is easy to be driven.
Operation principle：
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
