Description

Position finder of bearing

The present invention relates to a measuring device for measuring the position of the bearing installed on the shaft (rotating body) of the power plant, and more particularly to a bearing position measuring device to determine the position of the bearing before and after replacement and disassembly of the bearing. .

In general, nuclear power, hydropower, and thermal power plants have complex structures such as shafts, blades, couplings, and bearings. Regular and continuous maintenance of these various parts can ensure the stability and reliability of the facility.

In particular, since the shaft is supported by the bearing, the change in the position of the shaft is the result of the bearing position change.

In addition, the axis alignment is also changed.

As such, when the shaft is moved, the shaft must be moved back to its original position and the position of the bearing must be corrected.

However, when correcting the position of the bearing, there was a problem that can not measure whether the correct position of the bearing is made correctly.

Therefore, there is a problem that it is difficult to obtain data for accurate position determination in bearing maintenance.

Accordingly, the present invention has been proposed to solve the above-mentioned problems according to the prior art, and an object of the present invention is to provide a position measuring device of a bearing to check the position of the bearing before and after replacement and disassembly of the bearing.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the bearing position measuring apparatus according to the present invention will be described.

1 is a view showing a state in which a shaft is installed in the position measuring device of the bearing according to the present invention, Figure 2 is a cross-sectional view of Figure 1, Figure 3 is a side cross-sectional view of FIG.

As shown in Figs. 1, 2 and 3, a shaft (rotary body) 10 for rotating or linear movement, and a bearing installed on one side of the outer circumferential surface of the shaft 10 to support the shaft 10; And a bearing position measuring device 30 for accommodating the shaft 10 and the bearing 20 and measuring a change in position of the bearing 20 accommodated therein.

The bearing position measuring device 30 forms an accommodating part 33 between the first and second partition walls 31 and 32, and a shaft 10 having the bearing 20 installed therein as the accommodating part 33. Bearing posts 34 of the " Ｕ " shape and formed on the upper surfaces of the first and second bulkheads 31 and 32 at regular intervals, the main support bar 36 to be described later. The main support for supporting and fixing the fixing hole (Hall) 35 for inserting and fixing one end portion, and the one end is inserted and fixed in the fixing hole 35 and the auxiliary support bar 37 to be described later to the other end thereof. An auxiliary support bar for fixing the bar 36 and one end thereof to a fixing hole formed at the other end of the main support bar 36 and supporting a straight edge 38 to be described later. (37) and a scale for measuring the position on the upper surface thereof, and is provided at the other end of the auxiliary support bar (37) to provide a bearing (20). It is composed of a straight-edge 38 for measuring the change in position of.

Here, the main support bar 36 and the auxiliary support bar 37 is preferably removable.

In addition, the auxiliary support bar 37 and the straight-edge 38 is preferably formed integrally.

Referring to the installation process and operation of the bearing position measuring device according to the present invention configured as described above are as follows.

First, the bearing stand 34 of the "Ｕ" shape is positioned at the lower part of the shaft 10 to measure the position of the bearing 20.

And the shaft 10 in which the bearing 20 was provided is accommodated in the accommodating part 33 of the bearing stand 34 of a "" "shape.

Thereafter, one end of the main support bar 36 is fixedly inserted into the fixing holes 35 formed in the first and second partition walls 31 and 32 of the “대” -shaped bearing base 34.

In addition, the fixing hole formed at the other end of the main support bar 36 is inserted into and fixed to one end of the auxiliary support bar 37 integrally connected with the straight edge 38 having the measurement scale.

The straight edge 38 measures and records the initial positions of the front and rear surfaces of the bearing 20.

On the other hand, after a certain time, the position of the front and rear of the bearing 20 is recorded and recorded with the straight edge 38 at a necessary time.

Then, the initial position values of the front and rear surfaces of the bearing 20 measured on the straight edge 38 and the position values of the front and rear surfaces of the bearing 20 measured at the required time are compared, and the result is determined. Record it.

Therefore, data necessary for accurate position determination at the bearing maintenance site is recorded, so that the bearing can be positioned on the shaft at the correct position when the bearing is assembled.

As described above, the present invention can accurately measure the position of the bearing installed on the shaft, and thus, there is an effect of proactively coping with reliability maintenance and facility safety maintenance in the future.

In particular, there is an effect that can manage the important data required for accurate positioning in the bearing maintenance site.

Therefore, when assembling the bearing, there is an effect that the bearing can be positioned on the shaft in the correct position according to the data.
