Description

Technical Field

[0001] The utility model relates to a wheel centering measuring device for a large air compressor, belonging to the technical field of wheel centering for a large air compressor. Background Art

[0002] When installing rotating equipment, it is necessary to locate the center of the shaft system and the wheels. Conventional wheel centering generally uses the stand method, in which a stand rod is fixed to one side of the wheel and a dial indicator is mounted on the stand rod to contact the other side of the wheel. The other wheel rotates, and the axial and radial deviations of the wheels are measured by the dial indicator. The center of the wheel is adjusted according to the measured values. However, this method can only be used when the two pairs of wheels are close to each other. When the two pairs of wheels are far apart, it is difficult to measure. Simply extending the stand rod for measurement will also cause large errors, affecting the alignment accuracy. In order to adapt to the centering measurement of wheels that are far apart and improve the alignment accuracy, measuring tools using laser alignment instruments and magnetic dial indicator stands have appeared in the prior art. However, laser alignment instruments are expensive, and the base of the magnetic dial indicator stand is easy to slide and has insufficient rigidity when the magnetic dial indicator stand is fixed. In CN201820112908.5- A convenient measuring tool for turbine shaft alignment and CN202320805607.1- A tripod for centering the axis of large equipment, both schemes use a suspended long rod as a support rod for the dial indicator to extend the measuring distance and achieve measurement when two pairs of wheels are far apart. They have good installation stability and low cost. However, the spacing and diameter sizes of wheels of different specifications are not equal. In the above schemes, a single support rod is difficult to meet the connection and measurement requirements of multiple pairs of wheel spacings and diameters, and its practicality is limited.

[0017] Combine the following Figures 1 to 4 The embodiments of the utility model are described in detail.

[0018] A large air compressor wheel centering measuring device is characterized in that it includes a detachable adapter plate 1 connected to the end face of the pair of wheels 100 and a telescopic measuring component 2 connected to the adapter plate 1 and arranged along the axial direction of the pair of wheels, the telescopic measuring component 2 includes a telescopic cylinder 3 connected to the adapter plate 1 at one end and with a telescopic length, a meter frame 4 installed at the other end of the telescopic cylinder 3, a radial dial indicator 5 installed on the meter frame 4 for measuring the radial runout value of the pair of wheels 101, and an axial dial indicator 6 installed on the meter frame 4 for measuring the axial runout value of the pair of wheels 404.

[0019] The above-mentioned large air compressor wheel centering measurement device includes an adapter plate 1 and a telescopic measuring component 2. The telescopic measuring component 2 is connected to the wheel pair 100 through the adapter plate 1. The adapter plate 1 is used to connect wheels of different diameters to adapt to the connection between wheels of different diameter specifications and the telescopic measuring component. The length of the telescopic tube 3 is telescopic. The position of the table frame 4 is adjusted by the telescopic tube 3 to adapt to the centering measurement of wheels with different spacings, meet the centering measurement needs of wheels with different diameters and spacings, and have high practicality.

[0020] The telescopic cylinder 3 includes a fixed cylinder 31 connected to the adapter pad 1 by bolts and arranged along the axial direction of the wheel 100, and an adjusting cylinder 32 extending into the fixed cylinder 31 through a guide. The fixed cylinder 31 is equipped with an adjusting positioning bolt 33, which is arranged radially. The adjusting cylinder 32 is positioned on the fixed cylinder 31 as the adjusting positioning bolt 33 is tightened, and can move on the fixed cylinder 31 as the adjusting positioning bolt 33 is loosened. The adapter pad 1 connects the wheel 100 and the fixed cylinder 31, and the guide in the fixed cylinder 31 extends into the adjusting cylinder 32. The length of the telescopic cylinder 3 is adjusted by the movement of the adjusting cylinder 32 on the fixed cylinder 31. When the length of the telescopic cylinder 3 is adjusted to the right position, the adjusting positioning bolt 33 is tightened to position the adjusting cylinder 32, so that the length of the telescopic cylinder 3 is temporarily determined. When it is necessary to adjust the length of the telescopic cylinder 3 again, the adjusting positioning bolt 33 is loosened so that the adjusting cylinder 32 can move on the fixed cylinder 31, and the inner end of the adjusting positioning bolt 33 is extended into the fixed cylinder 31 to press the adjusting cylinder 32 to position the adjusting cylinder 32. When the adjusting positioning bolt 33 is loosened, the inner end of the adjusting positioning bolt 33 does not contact the adjusting cylinder 32, and the positioning of the adjusting cylinder 32 is cancelled, so that the adjusting cylinder 32 can move on the fixed cylinder 31.

[0021] There are two adjusting positioning bolts 33, which are spaced apart along the axial direction of the fixed cylinder 31. The two adjusting positioning bolts 33 ensure the reliability of positioning the adjusting cylinder 32, and at the same time, after the adjusting positioning bolts 33 are tightened, the adjusting cylinder 32 is coaxially aligned with the fixed cylinder 31, and the telescopic cylinder 3 is axially arranged along the wheel 100.

The number of the strip connection holes 11 is two and they are symmetrically arranged on the upper and lower sides of the center hole 13. The number of the circular connection holes is four and they are evenly distributed on the periphery of the center hole. One end of the fixing tube fits on the adapter plate and is connected to the circular connection hole by bolts. The connection holes on the pair of wheels 100 of different diameters can all be connected to the strip connection hole 11, so that the strip connection hole 11 can adapt to the connection between the pair of wheels 100 of different diameters and the adapter plate 1. The adapter plate 1 fits on the end face of the pair of wheels 100, one end of the fixing tube 31 fits on the adapter plate 1, and the circular connection hole 12 is connected to the adapter plate 1 by bolts, ensuring that the fixing tube 31 is arranged along the axial direction of the pair of wheels 100.

The radial dial gauge 5 measures the radial runout value of the second wheel 101 when it rotates, and the axial dial gauge 6 measures the axial runout value of the second wheel 101 when it rotates. The deviation of the two centers of the two wheels is determined according to the measured values, and the adjustment amount and adjustment direction of the center of the second wheel 101 are determined.

[0024] There are two rack rods 41, one rack rod 41 is equipped with a radial dial gauge rod 42, and two rack rods 41 are equipped with axial dial gauge rods 43, and each axial dial gauge rod 43 is inserted with an axial dial gauge 6, and the measuring ends of the two axial dial gauges 6 are symmetrically arranged with the end face center of the wheel pair 101 as the center.
