[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 , the utility model provides an embodiment: a marine bearing device.

[0023] It includes: an external shell 01, which can limit the bearing shell 05 to prevent the bearing shell 05 from shaking and making abnormal noise during use. A covering inner ring 02 is fixedly provided on the middle inner side of the external shell 01. The covering inner ring 02 covers the gap between the bearing inner part 10 and the bearing shell 05 to prevent water from entering the bearing shell 05 from the gap between the bearing inner part 10 and the bearing shell 05 during long-term use, causing the bearing to be used unsmoothly. A fixing plate 03 is provided on the outer wall of the external shell 01, and a screw 04 is passed through the interior of the fixing plate 03. The inner side of the external shell 01 abuts against the bearing shell 05. One end of 05 is fixedly connected to the outer wall with an insert 06, which can be inserted into the groove of the bearing housing 05 to limit the fit of the two bearing housings 05 and avoid misalignment. The inner side of the bearing housing 05 is fixedly connected with a fixing rod 07, and the outer wall of the fixing rod 07 is connected with a roller 08. Both ends of the bearing housing 05 are provided with movable balls 09. The outer walls of the roller 08 and the movable balls 09 are in contact with the bearing inner part 10. After the bearing inner part 10 is removed, the roller 08 and the movable balls 09 are completely exposed to the outside, which is convenient for the staff to repair and replace the internal parts of the bearing. A convex ring 11 is fixedly provided in the middle of the inner side of the bearing inner part 10.

[0024] Furthermore, three fixing plates 03 are provided and symmetrically fixed on the outer wall of the outer shell 01 , which plays a role in force balance and avoids cracking on one side of the outer shell 01 .

[0025] Furthermore, the surface of the covering inner ring 02 fits with the inner side of the bearing inner part 10, and the covering inner ring 02 covers the gap between the bearing inner part 10 and the bearing outer shell 05 to prevent water from entering the bearing outer shell 05 through the gap between the bearing inner part 10 and the bearing outer shell 05 during long-term use, causing the bearing to be used poorly. The bearing outer shell 05 fits tightly with the outer shell 01, and the outer shell 01 can limit the bearing outer shell 05 to prevent the bearing outer shell 05 from shaking and making abnormal noises during use.

[0026] Furthermore, a groove is provided at one end of the bearing housing 05 away from the insert block 06 corresponding to the size of the insert block 06, and the insert block 06 can be inserted into the groove of the bearing housing 05 to limit the fit of the two bearing housings 05 and avoid misalignment.

[0027] Furthermore, the roller 08 is rotatably connected to the fixed rod 07. The roller 08 can rotate according to the use of the bearing inner part 10, generating rolling friction between the roller 08 and the bearing inner part 10, reducing the friction to the minimum and ensuring smooth use of the bearing inner part 10.

[0028] Furthermore, the movable ball 09 is embedded in the interior of the bearing housing 05 and is movably connected to the bearing housing 05, ensuring that the position of the movable ball 09 will not change. During the use of the bearing inner part 10, the movable ball 09 can rotate according to the use of the bearing inner part 10 to limit the two sides of the bearing inner part 10.

[0029] Furthermore, the bearing inner part 10 can be taken out in a direction away from the bearing housing 05, making it convenient to remove the bearing inner part 10 and completely expose the roller 08 and the movable ball 09 to the outside, making it convenient for subsequent staff to repair and replace the internal parts of the bearing. The inner diameter of the convex ring 11 is smaller than the inner diameter of the covering inner ring 02, ensuring that when the convex ring 11 is in use, the marine parts will not touch the covering inner ring 02. The covering inner ring 02 plays a shielding role, avoiding water from entering the bearing housing 05 through the gap between the bearing inner part 10 and the bearing housing 05 during the use of the bearing, causing the bearing to be used unsmoothly.

[0030] Working Principle: To use, first unscrew screw 04. Grasp the two outer shells 01 with both hands and pull them in opposite directions to separate them. Then, grasp the two bearing housings 05 with both hands and pull them in opposite directions. Insert 06 disengages from the groove of the other bearing housing 05. Finally, remove the bearing inner component 10, completely exposing the roller 08 and movable ball 09. This is the complete working principle of this utility model.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
