The measuring bar 10 is manufactured in a horizontal direction to fit the center distance between the driving side pulley 1 and the driven side pulley 2 fastened to transfer power to the V-belt 3. . At this time, the measurement bar 10 is manufactured by various lengths, for example, 500mm, 1,000mm, 1,500mm, etc. according to the center distance between the driven pulley (2) and the driving pulley (1).

The upper surface of the measuring bar 10 is attached to the ruler 11 is displayed a graduation of a predetermined interval.

The V-belt base 20 has a lower base 21 seated in a V-groove in which the V-belt 3 wound around the driven side pulley 2 and the driving side pulley 1 is fitted. The upper base 26 is assembled to the upper end of the lower base 21 is divided.

The lower base 21 has a measuring bar insertion groove 22 in which the measuring bar 10 is inserted in the upper surface thereof in the longitudinal direction, and has a driven side pulley 2 and a driving side pulley 1 at the center of the lower end. The V-shaped protrusion 24 seated in the V-groove is formed in the longitudinal direction like the measurement bar insertion groove 22. At this time, the V-shaped protrusion 24 of the lower base 21 is manufactured to meet the standard of the V-belt used in the conventional rotary pulley.

A measuring bar fixing bolt 31 for fixing the measuring bar 10 inserted into the measuring bar inserting groove 22 is inserted into the center of one side of the lower base 21 on which the measuring bar inserting groove 22 is not formed. Fixing bolt hole 23 is formed through the lower base 21 body to the measurement bar insertion groove (22).

The upper base 26 is assembled by a bolt 29 to the upper end of the lower base 21.

The upper base 26 has a level gauge 30 installed inside the center, and a level check groove for checking the level of the level gauge 30 from the outside on the upper surface where the level gauge 30 is installed. 27) is formed.

In addition, a dovetail groove 28 is formed on one side of the upper surface other than the level check groove 27 formed at the center of the upper base 26 in the rotation axis direction of the driven pulley 2 and the driving pulley 1. ) Is formed.

The spell 40 is mounted in the dovetail groove 28 of the upper base 26, in which the groove 28 has a dovetail shape so that the mounted spell 40 cannot escape upward. The spell 40 is displayed on the surface of the grid at regular intervals.

Referring to the accompanying drawings an embodiment of the axis alignment device of the V-belt-type rotating body having the above configuration will be described as follows.

4 is a state diagram used for the shaft alignment device of the V-belt-type rotating body of FIG.

Assemble the two upper bases 26 with bolts 29 on top of the two lower bases 21 to be seated in the V grooves on which the V-belts 3 of the driving side pulley 1 and driven side pulley 2 are wound. To complete the V-belt base 20.

Insert the measuring bar 10 manufactured according to the center distance between the driving side pulley 1 and the driven side pulley 2 in the measurement bar insertion groove 2 of the two V-belt-type base 20 completed. .

Then, the spell 40 is mounted in the dovetail groove 28 of the upper surface of the two V-belt-shaped base 20 connected by the measuring bar (10).

Thus, the shaft alignment device according to the present invention is completed as shown in FIG.

As shown in FIG. 4, the assembly of the shaft is completed by the V-belt 3, and the rotating body pulley transmits the rotational force of the driving side, for example, a motor, to the driven side, for example, a fan. (1) (2) is seated in the V groove where the V belt (3) is wound.

At this time, the shaft alignment device according to the present invention is seated in the outer V groove of the driving side pulley (1) and the driven side pulley (2), the V belt (3) is assembled to the remaining V groove. For example, if there are three V-grooves on which the V-belts 3 of the pulleys 1 and 2 are wound, the two V-belts are first assembled to the pulley, and then the axial alignment device according to the present invention is restrained from the outside. Seat in one V-groove.

When the shaft alignment device is located at the center of the side of the driving pulley (1) and the driven pulley (2), respectively, the measurement bar fixing bolt mounted to the fixing bolt hole 23 formed on one side of the lower base 21 ( Tighten 31) to fix the measurement bar (10) to move.

Next, after confirming the levels of the two pulleys through the level gauge 30 installed in the upper base 26 of the shaft alignment device according to the present invention seated on the driving side pulley (1) and driven side pulley (2), Check the assembly position of the pulley through the spell 40 mounted on the upper base (26).

After checking the level and assembly position of the two pulleys (1) and (2) is completed, each of the pulleys (1) (2) is fixed and then the V-belt (3) assembled using the drive pulley (1) Adjust the tension.

The shaft alignment device according to the present invention is not only used when assembling the V-belt (3) to the rotating body, the ruler 11 and the V-belt attached to the center of the measuring bar 10 even during maintenance of the rotating body. Using the spell 40 mounted on the upper base 26 of the mold base 20, the tension of the V-belt 3, as well as the level and assembly position of the rotating body can be accurately measured within a short time. In particular, in the case of maintenance work of a rotating body in a radiation zone such as a nuclear power plant, the level and assembly position of the rotating body can be measured within a short time, so that the working time can be shortened and the amount of radiation of the operator can be reduced.

What has been described above is just one embodiment of the axis alignment device of the V-belt-type rotating body according to the present invention, anyone of ordinary skill in the art to which the present invention belongs can be variously modified.

As described above, the axis alignment apparatus of the V-belt-type rotating body according to the present invention has the following effects.

First, by measuring the tension of the V-belt as well as the level and assembly position of the rotating body in a short time by using the ruler attached to the center of the measuring bar and the spelling on the V-belt base, maintenance quality regardless of the skill of the operator It can reduce the maintenance time and input manpower during maintenance, thereby reducing the maintenance cost of the equipment and increasing the efficiency of manpower operation.

Second, by measuring the length of the measuring bar according to the distance between the drive pulley and the driven pulley by the length is easy to work in a narrow space, there is an advantage to carry, such as handling, moving and transporting equipment.
