In general, a trunnion bearing is extrapolated to a gun barrel trunnion provided on a chariot, so that when the barrel is rotated in the up-and-down direction, It is a mechanical part that supports movement.

The trunnion bearing is composed of a cylindrical inner ring, a cylindrical outer ring coupled to the outer side of the inner ring, and a sliding layer formed on the inner peripheral surface of the outer ring so that the outer ring can slide on the outer side of the inner ring.

The outer circumferential surface of the inner ring is formed into a convex surface so that the inner ring does not separate from the outer ring when the inner ring slides inside the outer ring, and the inner circumferential surface of the outer ring has a concave surface corresponding to the convex surface.

Here, the conventional trunnion bearing forms a sliding layer by coating a liquid coating on the inner circumferential surface of the outer ring and then curing.

And in the step of deforming the outer ring into an elliptical shape, the largest inner diameter of the outer ring is deformed into an elliptical shape corresponding to the largest outer diameter of the inner ring.

The step of calibrating the outer ring in a circular shape is characterized in that, while rotating the outer ring, a protruding surface protruding outward beyond the turning radius of the outer circumferential surface of the outer ring is pressurized inward and calibrated in a circular shape.

In order to achieve the above object, a trunnion bearing according to the present invention is manufactured by the manufacturing method of the trunnion bearing.

The present invention relates to a trunnion which is extrapolated to a gun barrel of a gun barrel and is provided with a trunnion which rotatably supports the foil when the barrel is rotated in the vertical direction, To a method for manufacturing a bearing and a trunnion bearing manufactured thereby.

Particularly, the method of manufacturing a trunnion bearing according to the present invention and the trunnion bearing manufactured by the method can easily form a sliding layer on the inner circumferential surface of the outer ring and precisely couple the outer ring and the inner ring.

This feature is achieved by forming the sliding layer by spraying a powdery coating on the inner circumferential surface of the outer ring in the state of heating the outer ring and by forming the outer ring in an elliptic shape when the outer ring and the inner ring are engaged, This is achieved by calibrating the outer ring circularly.

Hereinafter, a method of manufacturing a trunnion bearing according to a preferred embodiment of the present invention and a trunnion bearing manufactured thereby will be described in detail with reference to the accompanying drawings.

A trunnion bearing according to a preferred embodiment of the present invention will be described.

The trunnion bearing 100 according to a preferred embodiment of the present invention is manufactured by the manufacturing method of the present invention and comprises the outer ring 200, the inner ring 300, and the sliding layer 400 as shown in FIG. .

First, the outer ring 200 constitutes the outer side of the trunnion bearing 100, which is formed in a ring shape having a predetermined diameter and length.

4, the inner circumferential surface of the outer ring 200 is curved so that the height of the inner circumferential surface of the outer ring 200 gradually decreases from both side edge portions to the center of the concave surface, (210).

Next, the inner ring 300 is formed in a ring shape having a predetermined diameter and a length, and is configured to be slidably coupled to the inner side of the outer ring 200. The inner ring 300 is formed as an inner side of the trunnion bearing 100.

The inner circumferential surface of the inner ring 300 is curved so as not to be separated from the outer ring 200 when sliding on the inner side of the outer ring 200, It is preferable that the convex surface 310 is formed to be higher than the convex surface 310.

That is, the outer diameter of the inner ring 300 with respect to the highest height portion of the convex surface 310 of the inner ring 300 is set to be larger than the outer diameter of the concave surface 310 of the outer ring 200 210 is larger than the inner diameter of the outer ring 200 with respect to the highest height portion. However, the inner diameter of the outer ring 200 is based on the assumption that the inner diameter of the outer ring 200 includes the height of the slip layer 400 to be described later.

3, the inner ring 300 is preferably longer than the length of the outer ring 200 so as to protrude outward from the outer ring 200, as shown in Fig. 3, so as to support the foil of the barrel with a larger area .

The sliding layer 400 is formed on the outer ring 200 so that the sliding layer 400 can slide on the inner side of the outer ring 200 when the inner ring 300 is coupled to the inner ring 300, (200).

The sliding layer 400 may have a predetermined thickness so that the inner ring 300 is not separated from the inner side of the outer ring 200 and the outer circumferential surface of the sliding layer 400 corresponds to the convex surface 310 of the inner ring 300 desirable.

The sliding layer 400 is smoothly operated at a temperature of -40 to 40 ° C. and is not deformed even in the temperature range after the curing so as to be able to withstand the high load conditions caused by the impact load due to the impact load caused by the foam- And TFE (Tetrafluoroethylene) resin having properties such as high mechanical strength and the like.

However, the tetrafluoroethylene resin is sprayed in the form of powder on the inner circumferential surface of the outer ring 200 heated to a predetermined temperature so as to be coated with a uniform thickness, and is melted and fixed by the self-heat of the outer ring 200, .

That is, the outer ring 200 is heated at a temperature at which the tetrafluoroethylene resin powder can be fixed while being melted, and then sprayed on the inner circumferential surface of the outer ring 200 to form the sliding layer 400.

A method of manufacturing a trunnion bearing according to a preferred embodiment of the present invention will be described.

A method of manufacturing a trunnion bearing according to a preferred embodiment of the present invention includes a preparation step (S100), a coating step (S200), a combining step (S300), and a calibration step (S400) desirable.

First, the preparing step S100 is a step of preparing the outer ring 200 and the inner ring 300 into a predetermined shape.

At this time, the outer ring 200 is formed to be ring-shaped and the inner circumferential surface of the concave surface 210 is formed to be convexly concave toward the central portion. The depth of the concave surface 210 may be 1.0 to 2.0 mm.

The inner ring 300 is formed by forming a ring and engaging the inside of the outer ring 200 so as to have a slidable diameter and having an outer circumferential surface formed of a convex surface 310 corresponding to the concave surface 210, The height of the central portion of the convex surface 310 may be machined to be 1.0 to 2.0 mm corresponding to the depth of the central portion of the concave surface 210.

Next, in the coating step S200, the tetrafluoroethylene resin is sprayed onto the concave surface 210, which is the inner surface of the outer ring 200 prepared in the preparation step S100, to form a slip layer 400 having a uniform thickness, .

For this, the coating step S200 may include a heating step S210, a spraying step S220 and a grinding step S230 as shown in FIG.

The heating step (S210) is a step of heating the tetrafluoroethylene resin to 300-500 占 폚 so that the tetrafluoroethylene resin is melted and fixed when injected into the inner surface of the outer race (200) in powder form. That is, the heating step S210 allows the tetrafluoroethylene resin to be injected in a powder state rather than in a liquid state, thereby making it possible to easily form the slip layer 400 with a uniform thickness.

The injection step S220 includes forming the slip layer 400 by uniformly spraying powdered tetrafluoroethylene resin on the concave surface 210 which is the inner surface of the outer ring 200 heated in the heating step S210 to be. At this time, the slip layer 400 may be formed to a thickness of 0.5 to 0.8 mm.

The grinding step S230 is a step of grinding the outer surface of the slip layer 400 formed in the spraying step S220 so as to have a curved surface corresponding to the convex surface 310. At this time, the sliding layer 400 may be ground to a thickness of 0.2 to 0.4 mm in order to allow the inner ring 300 and the outer ring 200 to slide.

The coupling step S300 is a step of coupling the inner ring 300 to the inner side of the outer ring 200 where the sliding layer 400 is formed in the coating step S200 so as to be in the form of a trunnion bearing 100. [

To this end, the combining step S300 may be composed of a deforming step S310, an inserting step S320, and a force fitting step S330 as shown in FIG.

The deforming step S310 is a step of deforming the outer ring 200 into an elliptical shape so that the inner ring 300 can be inserted into the inner ring 200. When the outer ring 200 is deformed into an elliptic shape, the largest inner diameter of the outer ring 200 corresponds to the largest outer diameter of the inner ring 300 so that the inner ring 300 can be inserted into the outer ring 200 It can be transformed into an elliptical shape. At this time, however, it is assumed that the inner diameter of the outer ring 200 includes the sliding layer 400. This is because when the inner ring 300 is inserted into the inner ring 200 in the inserting step S320 to be described later, the inner ring 300 is inserted into the outer ring 200 without being directly passed therethrough. to be.

The inserting step S320 is a step of inserting one side of the inner ring 300 into the elliptically deformed outer ring 200 in the deforming step S310. In this case, the outer ring 200 and the inner ring 300 may be vertically inserted into the inner ring 300 with the outer ring 200 in a horizontal direction so that the radial directions of the outer ring 200 and the inner ring 300 are perpendicular to each other. Then, the inner ring 300 does not pass through the outer ring 200 but remains inserted.

In the inserting step S330, the inner ring 300 is inserted into the inner ring of the outer ring 200 in the inserting step S320, and the inner ring 300 is rotated in one direction, . 3, the inner ring 300 is completely inserted in the inner side of the outer ring 200 in the same manner as the radial direction of the outer ring 200.

Finally, the calibration step (S400) is a step of calibrating the outer ring (200) in which the inner ring (300) is completely inserted in the radially inward direction in the inserting step (S320). That is, the outer ring 200, which is deformed into an elliptical shape so that the inner ring 300 can be inserted into the inner ring 200, is circularly calibrated.

The reason for calibrating the outer ring 200 in a circular shape is that the inner ring 300 smoothly slides inside the outer ring 200 by a predetermined or greater rotational force with the sliding layer 400 interposed therebetween.

At this time, the calibration of the outer ring 200 may be performed by pressing the outer surface of the outer ring 200, which is coupled with the inner ring 300, in one direction, Do.

That is, the outer ring 200 is rotated in one direction, and the protruding surface protruding outward from the outer circumferential surface of the outer ring 200 is retrieved through the dial gauge while pressing the corresponding protruding surface with the pressing jig so as to be circular. However, in order to calibrate the outer ring 200 more precisely in a circular shape, it is preferable to repeat the above-described calibration work while rotating the outer ring 200 a plurality of times.

As described above, according to the present invention, the sliding layer can be easily formed on the inner peripheral surface of the outer ring, and the coupling between the outer ring and the inner ring can be precisely performed. Therefore, the manufacturing efficiency of the trunnion bearing can be greatly improved, .

The above-described embodiments are merely illustrative, and various modifications may be made by those skilled in the art without departing from the scope of the present invention.
