The main shaft 15 is rotatably supported by a bearing member 17 provided at an upper portion or an intermediate portion of the plurality of leg members 16. However, the foot member 16 to which the hydraulic motor 11 is mounted also serves as a cover box for the gear mechanism. The bearing member 17 has a bearing housing 18 and a sleeve 19 (or bearing) disposed therein so that lubricating oil can be provided The bearing housing 18 is supplied with a lubricating oil nozzle or the like.

At a predetermined position of the main shaft 15, the rope winch 20 and the chain winch 21 are rotatably transmitted through the first fixed hub members 22, 23 and the second fixed hub members 24, 25, respectively. However, there are cases where there are a plurality of rope winches 20 and chain winches 21.

One side of the first fixed hub members 22, 23 (in the direction of the arrow A in Fig. 8) is provided with a fixed tooth portion 27 that is engaged with the sliding tooth portion 32 so that the rotational power is transmitted from the main shaft 15 to the rope winch 20 and the chain winch. 21, the sliding tooth portion 32 is provided on the other side (direction of arrow B in Fig. 8) of the sliding hub member 30 which is slidably fitted to the angular axis sliding portion 28 having a substantially square cross section formed at a specific position of the main shaft 15. When the clutch levers 33 and 34 are operated to move the slide hub member 30, the clutches 35 and 36 having the sliding tooth portions 32 and the fixed tooth portions 27 are switched (started and stopped).

The gap between the fixed tooth portion 27 and the sliding tooth portion 32, and the gap between the angular shaft sliding portion 28 and the hub hole 37 of the sliding hub member 30 is often filled with lubricating oil. Since the lubricating oil flows out easily and sometimes pollutes the sea, a sealing member (for example, an oil seal) 38 is provided on one side of the sliding hub member 30, and a cover is provided around the sliding tooth portion 32 and the fixed tooth portion 27. The body 39 is provided with the through holes 40 in the first fixed hub members 22 and 23, so that the excessively placed lubricating oil or the like can be stored in the sealed space 42 of the main body portion 41 of the winches 20 and 21 and the main shaft 15.

However, the lubricating oil that has been supplied to the bearings of the second fixed hub members 24 and 25 is also left in the sealed space portion 42.

Detailed description of the preferred embodiment

Next, the embodiment of the present invention will be described with reference to the attached drawings. Incidentally, the same components as those of the winch device 10 of the conventional example shown in Figs. 7 and 8 may be the same.

As shown in Fig. 1 and Fig. 2, the winch device 60 of the first embodiment of the present invention has a base frame 60a which is finally fixed to a deck of a ship, a leg member 61 to 64 which is standing on the base frame 60a, and a through-hole member. The main shafts 15 supported by the bearing members 65 to 68 of the leg members 61 to 64 are rotatably supported. The bearing members 65 to 68 have bearing housings 69 to 72 fixed to the leg members 61 to 64 and bearings (for example, metal bushings) 73 to 76 respectively mounted on the inner side thereof, and further injected into the lubricating oil in the bearing housings 69 to 72. The holes 77 are respectively provided with lubricating oil nozzles 78, and the lubricating oil can be supplied between the bearings 73 to 76 and the main shaft 15.

The other side of the main shaft 15 (in the direction of the arrow B in FIG. 1) is fixed with a large gear 13 which is engaged with the pinion gear 12 provided on the output shaft of the hydraulic motor 11, and becomes the main shaft 15 by hydraulic pressure. The motor 11 is configured to rotate forward or reverse, and the hydraulic motor 11 is an example of a rotary drive source that is attached to a portion of the leg member 64 that also serves as a gear case. The spindle 15 is at a predetermined position A rope winch (an example of a winch) 80 for winding up or unwinding a rope, and, for example, two chain winches (an example of a winch) 81, 82, which can be pulled up or lowered by an anchor, are provided.

As shown in Figs. 1 and 2, the rope winch 80 has side plate members (side plates A, B) 83 and 84 and the main body portion 41 connected thereto, and the axial side of the left and right side plate members 83 and 84, respectively. The first and second fixed hub members 85 and 86 are attached to the predetermined position of the main shaft 15 so that the first and second fixed hub members 85 and 86 are rotatable. The first and second fixed hub members 85 and 86 have a cylindrical shape, and the lubricating oil nozzles 88 are provided in the individual lubricating oil injection holes 87 to form a structure in which the lubricating oil can be supplied to the bearings 89 and 90. Further, one side of the first fixed hub member 85 (in the direction of the arrow A in FIG. 1) has a fixed tooth portion 91 constituting a portion of the clutch means 96. However, in this embodiment, the bearings 89, 90 are formed of a metal bushing, and are arranged such that one side and the other side are stopped by the stoppers 89a, 90a, respectively, so that the bearings 89, 90 do not move.

Further, the main shaft 15 is provided with a sliding hub member 93 which is opposed to the fixed tooth portion 91 and has a slidable sliding tooth portion 92 on the other side, and the sliding hub member 93 has a specific position which can be formed at the spindle 15 The corner hole portion 94 is fitted and slidably moved through the corner hole 95. However, the fixed tooth portion 91 and the sliding tooth portion 92 constitute the clutch means 96, and by operating the clutch lever 97 in the axial direction, the clutch means 96 can be opened and closed, and the rotation and non-rotation of the rope winch 80 can be controlled. However, the distance d in Fig. 2 is the distance by which the sliding hub member 93 is movable.

The angular shaft sliding portion 94 is provided on the main shaft 15, and as shown in FIG. 3(B), the two-dotted line and the cylindrical material 98 shown by the solid line are planarly processed to form four sides 100. ～103, the cross section of the angular axis sliding portion 94 is formed in a square shape in which the corner portion is rounded, but the four corners are formed as circular arc portions 105 to 108 having a circular arc shape, leaving a portion of the cylindrical material 98.

On the other hand, the sliding hub member 93 having the corner hole 95 has the machining space portions 113 to 116 formed in the axial direction at four inner corners of the corner hole 95, and the corner hole 95 has four faces with the angular axis sliding portion 94. The three sliding surfaces 109~112 that are moved by 100~103 are sliding. The processing space portions 113 to 116 are located closer to the outer side in the radial direction than the arc portions 105 to 108, and the arc portions 105 to 108 are in contact with the sliding hub member 93.

The reason why the processing space portions 113 to 116 are provided is as described above because it is difficult to machine the four corners of the corner hole 95 along the arc portions 105 to 108 in substantially the same size, and the correct processing sliding surface 109 is formed. The buffer space of the tool at ~112 hours.

As shown in FIG. 3(A), the sliding hub member 93 has a lubricating oil injection hole 118 which is supplied between the angular shaft sliding portion 94 and the corner hole 95 and is opposed to the two lubricating oil injection holes 118. An annular lubricating oil groove 119 is provided at an inner end portion in the radial direction. The annular lubricating oil groove 119 has a groove bottom 120 that is larger than a radius of the circular arc portions 105 to 108.

As shown in FIG. 2, on one side of the sliding hub member 93, one side of the corner shaft sliding portion 94 is cylindrical and a sealing member (for example, an oil seal) 121 is provided so that the injected lubricating oil does not leak in the axial direction. . The main shaft 15 to which the sealing member 121 is attached is formed in a circular cross section, and the stainless steel pipe 122 is embedded in a portion where the sealing member 121 directly abuts and slides. Thereby, seawater or the like which may be invaded by the sealing member 121 can be blocked, and the lubricating oil can be prevented from flowing out from the inside. however, 123 denotes a seal fixing member which is screwed to the sliding hub member 93 to prevent the sealing member 121 from coming off.

On the other hand, as shown in Fig. 4(A), the radially inner side of the other side of the sliding hub member 93 is provided at the outlet of the corner hole 95 (outside of the angular axis sliding portion 94) to allow the processing space portions 113 to 116. The other side is covered with an annular cover member (e.g., a doctor blade) 125. The cover body 125 is formed of a soft metal plate such as a rubber plate, a plastic plate or a gunmetal. The inner side of the cover body 125 has a circular hole 126 having a smaller radius of curvature than the circular arc portions 105 to 108, and a plurality of screw holes 127 are provided on the outer side in the radial direction, and are fixed to the sliding hub by a plurality of screws. Member 93. However, the cover member may be divided into two in the circumferential direction (indicated by a single dotted line k in Fig. 4(A)) or divided into four, and the detachment may facilitate handling.

The inside of the cover member 125 is normally close to or abuts on the angular axis sliding portion 94, and even if the sliding hub member 93 is moved, the lubricating oil can be prevented from flowing freely, that is, the passage resistance of the lubricating oil is increased. In this manner, since the sealing member 121 is disposed at one of the sliding hub members 93 and the lid member 125 is provided at the other portion, the lubricating oil that has passed through the annular lubricating oil groove 119 can be prevented from leaking easily through the processing space portions 113 to 116. Further, the lubricating oil is filled in the sliding surface (surfaces 100 to 103) of the wider range of the angular axis sliding portion 94 by the movement of the sliding hub member 93.

Further, as shown in FIG. 4(B), the cover members 125a to 125d which individually cover the processing space portions 113 to 116 may be provided. In this case, the lid members 125a to 125d are fixed by screws screwed to the screw holes 127a to 127b.

The small-diameter cylinder 130 has a gap of 2 to 10 mm between the inner main shaft 15 and a space portion 131 for lubricating oil retention to retain the lubrication leaked from the first and second fixed hub members 85 and 86. oil.

Due to the above configuration, the lubricating oil injected from the lubricating oil injection hole 118 is sealed by the sealing member 121, and the other portion is temporarily plugged by the cover member 125. Here, even in the case where the lubricating oil leaks between the lid member 125 and the corner shaft sliding portion 94, the leaked lubricating oil becomes the lubricating material of the sliding tooth portion 92. The lubricating oil filled in the first and second fixed hub members 85 and 86 by the lubricating oil nozzle 88 passes through the bearings 89 and 90 and flows out from both sides of the bearings 89 and 90 to lubricate the bearings 89 and 90, and flows in. A space portion 131 formed between the small-diameter cylinder 130 and the main shaft 15 is formed.

However, since the volume of the space portion 131 is much smaller than the volume of the space portion formed between the main body portion 41 and the main shaft 15, a small amount of lubricating oil is injected to fill the space portion 131 to generate an impedance to the lubricating oil injection. Can grasp the filling status of the lubricating oil. However, in this embodiment, the lubricating oil flowing into the space portion 131 passes through the lubricating oil inflow path formed by the gap formed between the bearings 89 and 90 and the main shaft 15, but is additionally provided with a through hole or a through groove. Lubricating oil can also flow into the road. Further, in order to remove the lubricating oil entering the space portion 131, a discharge passage 131c (refer to FIG. 6) which is constituted by the small-diameter cylinder 130 and the tube 131a of the main body portion 41 and is often closed by the insert 131b is formed. Further, a cover covering the fixed tooth portion 91 and the sliding tooth portion 92 of the present embodiment is provided to prevent leakage of lubricating oil.

Next, the chain winches 81 and 82 shown in Fig. 1 will be described. The chain winches 81 and 82 integrally form the chain winch bodies 138 and 139 of the conventional structure, the bearing housing of the first fixed hub member, and the bearing housing of the second fixed hub member, respectively, and form a rotating body 140. 141 is rotatably attached to the main shaft 15 through a metal bushing 142 which is an example of a bearing housed inside the rotating bodies 140 and 141. However, the metal bushing 142 may be separately divided into two.

One of the rotating bodies 140 and 141 (one side and the other side in this embodiment) has fixed tooth portions 143 and 144 formed at a portion corresponding to the first fixed hub member. Further, the sliding hub members 148, 149 have sliding tooth portions 150, 151 that engage with the fixed tooth portions 143, 144, and the sliding hub members 148, 149 are provided with the angular shaft sliding portion of the main shaft 15 in a slidably movable manner. 146, 147.
