As shown in these drawings, the power transmission device for a winch according to the embodiment of the present invention mainly includes a rotary shaft 100, a driven side clutch 200, a drive side clutch 300, and a constraining ring 400 The restraining ring 400 is further coupled to the rotating shaft 100 by a key 500 that couples the driving side clutch 300 and the rotating shaft 100, Side clutch 200 and the bush 600 can be prevented from coming together with the drive-side clutch 300 when the clutch 300 is separated from the driven clutch 200.

This will be described in more detail below for each configuration.

First, the rotating shaft 100 is a portion for transmitting the driving force of the driving motor 110.

The rotating shaft 100 may be directly coupled to the driving motor 110 or may be rotated by receiving a driving force through a power transmitting mechanism such as a speed reducer (not shown).

A key groove 120 is formed on the circumferential surface of the rotary shaft 100 and a key 500 having a part protruding outward is fixed in the key groove 120.

In particular, the key 500 is provided in a plurality of two or more, and preferably, the key 500 is provided on opposite sides of the circumferential surface of the rotary shaft 100 so that the rotational driving force of the rotary shaft 100 is transmitted to the driving side So that it can be smoothly transmitted to the clutch 300.

4, the key 500 may be fixed to the circumferential surface of the rotary shaft 100 using a bolt (or a screw) 510, so that the key 500 may be fixed to the rotary shaft 100 The key groove 120 of the key groove 120 can be prevented from being separated.

Next, the driven side clutch 200 is a portion for rotating the winding drum 600 by the driving force of the rotating shaft 100. At this time, the winding drum 600 is a portion where a rope or a chain for towing or mooring is to be wound, and is installed to be rotated while interlocking with the driven side clutch 200.

The driven side clutch 200 is formed in a cylindrical shape or a ring shape and is rotatably coupled to the circumferential surface of the rotation shaft 100. The driven side clutch 200 is rotatably coupled to the rotation shaft 100 and between the rotation shaft 100 and the driven side clutch 200 Side clutch 200 can be stably coupled to the rotary shaft 100 by interposing the bush 210 therebetween while the driven side clutch 200 is rotated in the rotation of the rotary shaft 100 It is configured not to be affected.

At this time, although the bush 210 may be constituted by a conventional ring-type bush, it is more preferable that the bush 210 has a bearing structure for smooth rotation of the rotary shaft (or the driven side clutch) 100.

Next, the driving-side clutch 300 is a portion that transmits the driving force of the rotating shaft 100 to the driven-side clutch 200 to rotate the driven-side clutch 200.

The drive side clutch 300 is formed by a key 500 fixed to the circumferential surface of the rotary shaft 100 while being formed in a cylindrical shape (or a ring shape) to be coupled to surround the circumferential surface of the rotary shaft 100, And is coupled to the rotating shaft 100 so as to transmit power.

A sliding groove 310 is formed on the inner circumferential surface of the driving side clutch 300 so that the key 500 protruding from the circumferential surface of the rotating shaft 100 can be received. The drive-side clutch 300 can be rotated together.

In addition, the drive-side clutch 300 is installed so as to be slidable toward the driven-side clutch 200. That is, the drive-side clutch 300 is guided by the key 500 protruding from the rotary shaft 100 and is selectively slidably moved in the axial direction of the rotary shaft 100 to selectively contact the driven- . At this time, the sliding movement of the driving-side clutch 300 is performed by the piston 320. However, the present invention is not limited to this, and the driving-side clutch 300 may be configured to be slidable by various kinds of horizontal driving devices.

In particular, the engaging teeth 230 and 330 are formed on the opposite surfaces of the drive-side clutch 300 and the driven-side clutch 200 so as to correspond to each other, The side clutch 300 and the engagement teeth 230 and 330 of the driven side clutch 200 are engaged and rotated together or the engagement teeth 230 and 330 are disengaged from each other to prevent the driven side clutch 200 from rotating do.

On the inner peripheral surfaces of the opposite surfaces of the two clutches 200 and 300 on the inner peripheral surfaces of the driven clutch 200 and the driven clutch 300, receiving grooves 240 and 340 for receiving the restricting ring 400, The key groove 120 formed in the rotary shaft 100 and the end of the key 500 installed thereon are inserted into the receiving recesses 240 and 340 of the driven clutch 200 and the driving clutch 300, To a restraining ring (400) located within the retaining ring (400).

When the drive-side clutch 300 is disengaged from the driven-side clutch 200, the retaining ring 400 is engaged with the driven-side clutch 300 together with the driven-side clutch 200 and the bush 210 It is a part to prevent coming.

The restricting ring 400 is formed in a ring shape surrounding the circumferential surface of the rotating shaft 100 and is rotatably supported by the receiving side of the driven side clutch 200 and the driving side clutch 300 among the circumferential surfaces of the rotating shaft 100. [ And is positioned inside the grooves 240 and 340.

Particularly, since the diameter of the restraining ring 400 is at least equal to or greater than the diameter of the bush 210, the restraining ring 400 is formed to be smaller than the inner diameter of the receiving recesses 240 and 340 of the clutches 200 and 300, (400) can be stably positioned in the receiving recesses (240, 340) and can be kept in contact with the bush (210) and the driven clutch (200).

A portion of the key 500 positioned so as to protrude into the receiving groove 340 of the driving-side clutch 300 is engaged with the engaging ring 400 on the surface opposite to the driving- The mounting groove 410 is formed to be recessed. That is, the constraint ring 400 is not configured to be coupled to the rotary shaft 100 by passing a bolt (not shown) through the circumferential surface of the constraint ring 400, So that it can be coupled to the rotary shaft 100, and the working time for mounting the constraining ring 400 can be remarkably shortened.

At this time, the position of the mounting groove 410 formed in the restraining ring 400 is formed at a position opposite to the key 500 fixed to the rotating shaft 100, and the quantity of the mounting groove 410 is The number of the keys 500 may be the same as the number of the keys 500 or more than that of the keys 500 may be formed.

Hereinafter, the assembly process of the winch power transmission apparatus according to the embodiment of the present invention described above will be described in more detail.

First, the key 500 is fixedly installed in each of the key grooves 120 formed on the circumferential surface of the rotary shaft 100. At this time, the key 500 is fixed in the key groove 120 using a bolt (or a screw) 510. This is as shown in Fig. 4 attached hereto.

After the installation of the key 500 is completed, the position of the mounting groove 410 of the restricting ring 400 in the state where the restricting ring 400 is coupled to the rotating shaft 100 is determined by the position of the key 500 So that the key 500 is received in the mounting groove 410 through movement of the restricting ring 400 so that the rotation shaft 100 and the restricting ring 400 are engaged with each other, The restraining ring can be rotated together with the rotating shaft. This is as shown in Fig. 5 attached hereto.

Thereafter, the drive-side clutch 300 and the driven-side clutch 200 are installed on the rotating shaft 100 with the constraint ring 400 interposed therebetween. That is, the driven side clutch 200 is rotatably installed on the circumferential surface of the rotary shaft 100 using the bush 210, and the drive side clutch 300 is fixed to the rotary shaft 100 So as to be coupled with the key 500 to transmit power to the rotating shaft 100. At this time, the constraining ring 400 is in contact with the end surface of the driven side cleat 200 and the end surface of the bush 210 in a state of being positioned in the receiving groove 240 of the driven side clutch 200 .

Of course, at least one of the clutches 200 and 300 may be coupled to the rotary shaft 100 without the constraint ring 400 installed.

Therefore, the assembling of the winch power transmission apparatus according to the embodiment of the present invention is completed by the above-described operation.

Although not shown, after the above-described winch power transmission apparatus is assembled, the drive side clutch 300 is further coupled with a piston (or other horizontal drive apparatus) 320 for its axial movement .

Next, the power transmission process by the power transmission device for a winch of the above-described structure will be described in more detail.

First, when the power transmission to the winding drum 600 is not performed, the drive side clutch 300 is held in a state of being separated from the driven side clutch 200 by the action of the piston 320. [ This is as shown in Fig.

At this time, even if the rotating shaft 100 is rotated by driving the driving motor 110, only the rotation of the driving side clutch 300 is performed and the driven side clutch 200 is not rotated, The drum 600 is also not rotated.

When the operation control for winding the rope (or the chain) to the winding drum 600 is performed in the above-described state, the piston 320 is moved to move the driving-side clutch 300.

In this case, the drive-side clutch 300 is horizontally moved to the side where the driven-side clutch 200 is positioned, and engaged with the driven-side clutch 200 as shown in FIG. 6, The driven side clutch 300 is also rotated and the driven side clutch 200 engaged with the driven side clutch 300 is rotated together with the rotation of the rotating shaft 100 by the driving of the driven side clutch 300. [

Therefore, the rope (or the chain) is wound around the outer peripheral surface of the winding drum 600 while the winding drum 600 is rotated by the rotation of the driven side clutch 200.

On the other hand, when the operation control for stopping the rotation of the winding drum 600 is performed after the winding of the rope is completed, the drive side clutch 300 is disconnected from the driven side clutch 200 while the piston 320 is operated again As shown in FIG.

As a result, the engagement teeth 230 and 330 of the driven side clutch 200 and the drive side clutch 300 are separated from each other so that the driven side clutch 200 and the winding drum 600 interlocked with the driven side clutch 200 are no longer rotated .

In the process of separating the engaged teeth 230 and 330 of the driven clutch 200 and the driven teeth 300 of the driven clutch 300 from each other by the coupling force between the respective teeth 230 and 330, The phenomenon of being moved together along the clutch 300 occurs.

However, since the retaining ring 400 is fixedly positioned in the receiving groove 240 of the driven side clutch 200, the driven side clutch 200 can not be moved and the driven side clutch 300 The engagement with the driven side clutch 200 can be released.

As a result, in the power transmission device for a winch according to the present invention, the movement of the driven side clutch 200 can be prevented by the constraint ring 400.

Particularly, since the constraining ring 400 is configured to be kept fixed to the rotary shaft 100 using the key 500, it is easy and simple to assemble the constraining ring 400, It becomes possible to proceed the assembling work by a non-skilled person.
