Hereinafter, embodiments of a power transmission device of an excavator bucket rotating link according to the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known techniques will be omitted to avoid obscuring the subject matter of the present invention.

FIG. 1 is a perspective view showing a power transmission device of an excavator bucket rotating link according to a first embodiment of the present invention, FIG. 2 is a partial cutaway perspective view showing a three-dimensionally inner structure of a power transmitting device of the excavator bucket rotating link of FIG. 1 (A) is a plan view of the power transmission device of the excavator bucket rotary link of Fig. 1, and (b) and (c) are plan views of the power transmission device of the excavator bucket rotary link of Fig. 1 Fig. 3 is a view showing a conventional rotating device of an excavator bucket. Fig.

Referring to Figs. 1 to 3, an excavator bucket rotary link transmission system according to a first embodiment of the present invention is provided between an arm of an excavator and a bucket to provide rotational power to the bucket, A worm gear shaft 300, a support block 400, a drive motor 500, and a power transmission unit 600. The worm gear shaft 300 includes a worm wheel 300,

As shown in FIG. 2, the fixed plate 100 is formed by integrally forming a worm casing 110 in a tangential direction on one side of a cylindrical shape, and an upper portion of the worm casing 110 is coupled to an arm of an excavator via an upper body do.

The fixing plate 100 is made of a material such as steel or phosphor bronze and has a structure in which a portion in contact with the warm casing 110 is opened and communicated with each other.

The turntable 200 is rotatably supported on the inner side of the fixed base 100 and a bucket of the excavator is coupled to the lower side of the fixed base 100 via a coupler lower body (not shown).

The rotating disc 200 includes an outer circumference 201 having a ring gear 210 formed thereon, a sloped surface 202 which slopes inwardly from the outer circumference 201 and rolls through the bearing with the fixed disc 100, And a vertical extending surface 203 extending perpendicularly from the fixed plate 100 and interposed between the fixed plate 100 and the sealing member C. [

The worm gear shaft 300 is mounted in the worm casing 110 of the fixed base 100 so as to be engaged with the ring gear 210 of the rotating disk 200.

As shown in FIG. 3, one end of the worm gear shaft 300 passes through one side of the worm casing 110, and the other end of the worm gear shaft 300 is connected to the outside .

The support block 400 includes a lower half portion 410 coupled to one side of the warm casing 110 of the fixed base 100 and having a first through hole 411 formed therein for allowing the worm wheel shaft 300 to pass therethrough, And an upper half portion 420 extending toward the arm of the second through hole 421 and formed with a second through hole 421.

The power transmission part 600 is disposed on the outer surface of the support block 400 at a predetermined depth so that the power transmission part 600 to be described later is installed as close as possible to the worm casing 110 while reducing the weight of the support block 400. [ The built-in groove 430 is formed in a track shape.

It is preferable that the cover block 700 is coupled so as to cover the outer surface of the support block 400 so as to prevent foreign matter from flowing into the power transmission portion 600.

The drive motor 500 is coupled to the inner surface of the support block 400 adjacent to the worm casing 110 such that the drive shaft 510 is inserted into the second through hole 421 of the support block 400. In this embodiment, the drive motor is a hydraulic motor operated by a high-pressure fluid.

The power transmission unit 600 connects the end of the drive shaft 510 of the drive motor 500 and the end of the worm gear shaft 300 by means of the sprocket 610 and the chain 620, To the shaft (300). In the present embodiment, the power transmission unit 600 is applied with a double chain system capable of transmitting stable power.

The drive shaft 510 of the drive motor 500 and the worm gear shaft 300 are pulled together so that the shaft can be bent while receiving a strong bending force.

As a countermeasure to this, a pair of sprockets 610 applied to the power transmitting portion 600 are formed with hubs 611 protruding outward from the support block 400, and the hub 611, which faces the hub 611, A pair of roller bearings 800 are inserted and fixed at predetermined depths in the upper and lower portions of the inner surface of the block 700, respectively.

The roller bearing 800 provided with a plurality of rolls 810 between the inner and outer rings can support the hub 611 rotatably because the support width of the roller bearing 800 is wider than that of the ball bearing.

The rotating device of the excavator bucket according to this embodiment thus structured has a structure in which the drive motor 500 is connected to the coupler body 11 as shown in Figure 4 (a) through the flange connection between the arm- Shaped rigid body) that is formed in a flat plate shape.

Since the drive motors 23 and 112 are directly transmitted with power as shown in the following (b) and (c) of the related art, the drive motors 23 and 112 are disposed outside the coupler body 11 (A2).

In the combined operation in which the excavating operation of the bucket of the excavator, the tilting operation in the left and right directions, and the rotating operation of the shaft are performed in combination, the outer area A2 of the coupler body 11 has a possibility of interference with the adjacent parts, The possibility of interference with the same work object is relatively large.

Therefore, in the structure in which the drive motor is exposed to the outside as in the prior art, there is a high risk of interference of the drive motor in the process of operating the bucket of the excavator.

On the other hand, in this embodiment, as shown in FIG. 4A, the drive motor 500 is installed in the inner area A1 of the coupler body 11 having a relatively low interference possibility, There is no danger, and the bucket can be operated more smoothly regardless of the risk of interference.

Hereinafter, a power transmitting apparatus for an excavator bucket rotating link according to a second embodiment of the present invention will be described. The same reference numerals as those of the first embodiment denote the same components, and a description thereof will be omitted.

FIG. 5 is an exploded perspective view showing a power transmitting device of an excavator bucket rotating link according to a second embodiment of the present invention, and FIG. 6 is a view illustrating a detailed configuration of an idler included in the power transmitting device of the excavator bucket rotating link of FIG. FIG.

5, the idler 900 for holding the tension by pressing the chain 620 of the power transmitting portion 600 is coupled to the inner surface of the cover block 700, as shown in FIG.

To precisely adjust the tension of the chain 620, the idler 900 includes a pressing portion 901 having a friction surface that presses the chain 620 as shown in Fig. 6, a pressing portion 901 extending from the pressing portion 901, And a hinge unit 902 hinged to the hinge unit 700. The adjusting bolt 910, the nut member 920 and the torsion spring 930 may be further provided.

The nut member 920 is fixed to the cover block 700 adjacent to the chain 620 and the adjustment bolt 910 is screwed to the nut member 911 to connect the pressing portion 901 of the idler 900 to the chain 620).

A torsion spring 930 is coupled to the hinge portion 902 so that the torsion spring 930 provides an elastic restoring force to the idler 900 so that the pressing portion 901 is separated from the chain 620.

On the other hand, the power transmission system using the sprocket 610 and the chain 620 can securely and reliably transmit the power and has a merit of being semi-permanent, but it has a disadvantage of periodically applying lubricant such as grease. In addition, there is a disadvantage that the degree of tension of the chain 620 must be periodically checked.

Since the power transmitting portion 600 is covered by the cover block 700 as shown in FIG. 5, it is difficult to remove the cover block 700 in order to check the lubrication state and the tension state of the chain 620 May occur.

As a countermeasure thereto, the present embodiment further includes a visual observation unit 1000 composed of a sunlight window 1010 and an observation light 1020. [

A first through hole is formed in the center of the support block 400 to mount the sunshade window 1010 and the observation light 1020. A second through hole is formed in the center of the cover block 700 facing the first through hole Respectively.

The observation light 1020 is coupled to the second through hole of the cover block 700 that is easy to be visually observed and the sunlight window 1010 is coupled to the first through hole of the support block 400 opposite thereto.

If there is no sunshade window 1010 in the support block 400 and only the observation sunshine 1020 is present in the cover block 700, the interior space provided with the power transmission portion 600 when the observation sunshine 1020 is lighted It is desirable that the chain 620 is provided up to the sunshade window 1010 so as to face the observation light 1020 because the lubrication state and the tension state of the chain 620 can not be properly confirmed.

In the present embodiment, an observation lens 1020 is equipped with a magnifying lens capable of magnifying observation, and a transparent glass or transparent plastic through which light can pass is mounted on the sunshade window 600.

Hereinafter, a power transmission device for an excavator bucket rotating link according to a third embodiment of the present invention will be described. The same reference numerals as those of the first embodiment denote the same components, and a description thereof will be omitted.

7 is a view for explaining a power transmission device of an excavator bucket rotating link according to a third embodiment of the present invention.

Referring to FIG. 7, in the present embodiment, the return type of the power transmitting portion 600 is applied as it is, and the sprockets 610 have different diameters. The sprocket 610a disposed inside the inner groove 430 of the support block 400 has a relatively large diameter and the outer sprocket 610b has a relatively small diameter.

This is because it is necessary to couple two chains to the sprocket 610 inserted in the built-in groove 430, because it is difficult to chain the sprockets on the inner side if the outer diameter of the sprockets is the same or larger.

As the diameter of the sprocket is different, the idler 900 for holding the tension by pressing the chain 620 is composed of a plurality of sprockets. An idler 900a for pressing the chain 620a caught by the inner sprocket 610a and an idler 900b for pressing the chain 620b caught by the outer sprocket 610b.

In addition, it is preferable in terms of maintenance that a lubricant injection hole 750 is formed in a long hole extending at one point of the cover block 700 through which the chain passes, and a separate shielding plug (not shown) is inserted and fixed thereto.

Hereinafter, a power transmission device for an excavator bucket rotary link according to a fourth embodiment of the present invention will be described. The same reference numerals as those of the first embodiment denote the same components, and a description thereof will be omitted.

8 is a view for explaining a power transmitting device of an excavator bucket rotating link according to a fourth embodiment of the present invention.

Referring to FIG. 8, in the present embodiment, a double chain type is directly applied to the power transmission portion 600, and a pair of gears 1100 ) Are further included.

The pair of gears 1100 are interposed between the sprockets 610c coupled to the drive shaft 510 of the drive motor 500 and the gears of the sprockets 610c so as to be rolling- A sprocket 610d coupled to the worm gear shaft 300 and a first gear 1110 interposed between the gears of the sprocket 610d so as to be in rolling contact with the first gear 1110, And a second gear 1120 of a cylindrical shape rotatably coupled to the second gear 1100.

The first gear 1110 and the second gear 1120 are rotated in opposite directions to support the driving shaft 510 of the driving motor 500 and the worm gear shaft 300 so as not to be bent.

In the power transmission device of the excavator bucket rotating link constructed as described above, since the driving motor is installed in the inner area of the coupler body having a relatively low possibility of interference, there is no risk of interference of the driving motor, It is possible to obtain an effect that the bucket can be more smoothly operated without being affected.

In addition, in the present invention, a hub is protruded from a sprocket provided in a power transmitting portion, and is rotatably supported by a roller bearing of a cover block. In addition, since the chain is made of double rows and the tension of the chain is maintained by the idler, An effect that the power can be transmitted smoothly and stably can be obtained.

Particularly, the present invention has an effect of providing easy and easy maintenance while observing the lubrication state and tension state of the chain by installing a viewing window capable of magnifying observation on the cover block and providing a sunshade window for providing light to the supporting block Can be obtained.

The scope of the present invention is not limited to the above-described embodiments and modifications, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
