Abstract
The connecting device for the overspeed test of the compressor impeller mainly comprises a high-speed main shaft, the compressor impeller, a positioning gasket, a belleville spring and a locking nut, and is characterized in that the compressor impeller is sleeved on the high-speed main shaft through a spigot positioning sleeve, the positioning gasket, the belleville spring and the locking nut are sequentially installed on the high-speed main shaft in a sleeved mode, and the compressor impeller is not loosened in the high-speed rotation process of the overspeed test by screwing the locking nut to generate a pretightening force. The utility model relates to a simple structure, simple to operate, reliable compressor impeller overspeed test connecting device.
Description
Technical Field
The utility model relates to a compressor impeller overspeed test field.
Background
The overspeed tool for the traditional compressor impeller is complex in structure, troublesome in assembling and disassembling of the impeller, time-consuming and labor-consuming, unreliable in connection of the overspeed test process due to the tool, large vibration often occurs, and overspeed test cannot be completed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming above-mentioned technical defect, provide a simple structure, simple to operate, reliable compressor impeller overspeed test connecting device.
In order to achieve the purpose, the technical scheme mainly comprises a high-speed main shaft, a compressor impeller, a positioning gasket, a belleville spring and a locking nut, and is characterized in that the compressor impeller is sleeved on the high-speed main shaft through a spigot positioning sleeve, the positioning gasket, the belleville spring and the locking nut are sequentially installed on the high-speed main shaft in a sleeved mode, and the compressor impeller is not loosened in the high-speed rotating process of an overspeed test by screwing the locking nut to generate a pretightening force.
Due to the adoption of the technical scheme, the utility model discloses the installation time of compressor wheel overspeed test that significantly reduces, and installation operation structure is reliable, does not have the phenomenon that speeding up or slow down lead to becoming flexible too fast.
Drawings
FIG. 1 is a schematic structural view of a compressor impeller overspeed test connecting device;
in the figure: 1. a high-speed spindle; 2. a compressor impeller; 3. positioning the gasket; 4. a belleville spring; 5. and locking the nut.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
A compressor impeller overspeed test connecting device mainly comprises a high-speed main shaft (1), a compressor impeller (2), a positioning gasket (3), a belleville spring (4) and a locking nut (5), and is characterized in that the compressor impeller (2) is sleeved on the high-speed main shaft (1) through spigot positioning, the positioning gasket (3), the belleville spring (4) and the locking nut (5) are sequentially installed on the high-speed main shaft (1) in a sleeved mode, and pretightening force is generated by screwing the locking nut (5), so that the compressor impeller (2) is not loosened in the overspeed test high-speed rotation process. The locking nut (5) is rotated through the adjustable wrench, after the load applied by the wrench is borne, the belleville spring (4) deforms, certain potential energy is stored, pretightening force is generated, and the impeller is well prevented from loosening in the high-speed rotation process of the overspeed test. The scheme is very simple to install, and the overspeed test process is safe and reliable.
Therefore, the utility model relates to a simple structure, simple to operate, reliable compressor impeller overspeed test connecting device.
