Description

Technical Field

[0001] This utility model belongs to the field of ship rudder bearing technology, specifically a ship rudder bearing that can be quickly inspected and repaired. Background Technology

[0002] The rudder bearing is a core component of the ship's rudder system. It supports the rudder stock, bears the weight of the rudder blade and hydrodynamic forces, and also serves to seal against seawater intrusion and reduce friction. It is a key basic component for ensuring the ship's steering and maneuvering. The upper rudder bearing is located on the upper part of the rudder stock and is usually composed of a thrust ball bearing and a vertical sliding bearing. The rudder bearing housing is used to support and fix the upper rudder bearing to ensure the stability of the upper rudder bearing structure.

[0003] The existing ship rudder bearings have the following shortcomings: the existing ship rudder bearings are inconvenient to inspect and maintain. The existing ship rudder bearings are connected to the rudder bearing housing by multiple bolts. When inspecting the rudder bearings, it is necessary to remove the bolts one by one to remove the rudder bearings. The process is time-consuming and laborious, which leads to the extension of maintenance time and affects the efficiency of ship operation. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a ship rudder bearing that can be quickly inspected, solving the problem that existing ship rudder bearings are inconvenient to inspect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ship rudder bearing that can be quickly inspected, including a rudder bearing seat, a rudder bearing body disposed on the rudder bearing seat, a plurality of fixing holes being opened on the outer periphery of the rudder bearing body, a limit ring being fixedly connected to the outer periphery of the rudder bearing body, a plurality of support blocks being fixedly connected to the top of the rudder bearing seat, a slide rod being slidably connected to each support block, a connecting block being fixedly connected to one end of the slide rod, a fixing pin being fixedly connected to one side of the connecting block, a clamping assembly being disposed inside the rudder bearing seat, and a driving assembly being disposed on the rudder bearing seat.

[0006] As a further embodiment of this utility model: the clamping assembly includes a rotating ring, which is rotatably connected to the bottom of the rudder bearing seat. A worm gear is coaxially fixedly connected to the top of the rotating ring. Multiple arc-shaped through grooves are opened on the worm gear. A guide rod is provided in each arc-shaped through groove. The top of the guide rod is fixedly connected to the corresponding connecting block.

[0007] As a further embodiment of this utility model: the drive assembly includes a mounting base, which is fixedly connected to the rudder bearing seat.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution:

[0020] A ship rudder bearing capable of rapid maintenance includes a rudder bearing seat 1, a rudder bearing body 2 mounted on the rudder bearing seat 1, multiple fixing holes on the outer periphery of the rudder bearing body 2, a limit ring 3 fixedly connected to the outer periphery of the rudder bearing body 2, multiple support blocks 4 fixedly connected to the top of the rudder bearing seat 1, a slide rod 5 slidably connected to each support block 4, a connecting block 6 fixedly connected to one end of the slide rod 5, a fixing pin 7 fixedly connected to one side of the connecting block 6, a clamping assembly inside the rudder bearing seat 1, and a driving assembly mounted on the rudder bearing seat 1. An opening is provided for the rudder bearing body 2 to slide through. The limiting ring 3 on the outer periphery of the rudder bearing body 2 rests on the rudder bearing seat 1. The fixing pin 7 is firmly inserted into the corresponding fixing hole on the rudder bearing body 2 to fix the rudder bearing body 2. During maintenance, the drive component drives the clamping component to work. The clamping component drives the connecting block 6 away from the rudder bearing body 2. The connecting block 6 drives the slide rod 5 to slide on the support block 4. The fixing pin 7 is pulled out from the corresponding fixing hole, quickly releasing the rudder bearing body 2, saving maintenance time and improving efficiency.

[0021] The clamping assembly includes a rotating ring 8, which is rotatably connected to the bottom of the rudder bearing seat 1. A worm wheel 9 is coaxially fixedly connected to the top of the rotating ring 8. The worm wheel 9 has multiple arc-shaped through slots, and a guide rod 10 is provided in each arc-shaped through slot. The top of the guide rod 10 is fixedly connected to the corresponding connecting block 6. The worm wheel 9 has a circular opening. The top of the rudder bearing seat 1 has multiple guide slots, each of which is adapted to the corresponding guide rod 10. The drive assembly drives the worm wheel 9 to move. The worm wheel 9 rotates at the bottom of the rudder bearing seat 1 through the rotating ring 8. The worm wheel 9 forces the guide rod 10 to slide along the corresponding guide slot through the arc-shaped through slots. The guide rod 10 drives the corresponding connecting block 6 to move together.

[0022] The drive assembly includes a mounting base 11, which is fixedly connected to the rudder bearing 1. A servo motor 12 is fixedly connected to one side of the mounting base 11. The output end of the servo motor 12 passes through the mounting base 11 and is rotatably connected to it. A worm gear 13 is coaxially fixedly connected to the output end of the servo motor 12. The worm gear 13 meshes with the worm wheel 9. When the servo motor 12 is started, the output end of the servo motor 12 drives the worm gear 13 to rotate, and the worm gear 13 drives the worm wheel 9 to rotate.

[0023] The bottom of the rudder bearing seat 1 is provided with an installation ring 14, and multiple fixing blocks 15 are fixedly connected to the top of the installation ring 14. The top of each fixing block 15 is fixedly connected to the rudder bearing seat 1, and the rudder bearing seat 1 is installed on the deck of the cabin through the installation ring 14 at the bottom of the fixing block 15.

[0024] The working principle of this utility model is as follows:

[0025] The rudder bearing seat 1 has an opening through which the rudder bearing body 2 can slide. The limiting ring 3 on the outer periphery of the rudder bearing body 2 rests on the rudder bearing seat 1, and the fixing pin 7 is firmly inserted into the corresponding fixing hole on the rudder bearing body 2 to fix the rudder bearing body 2.

[0026] During maintenance, the servo motor 12 is started, and the output end of the servo motor 12 drives the worm gear 13 to rotate. The worm gear 13 drives the worm wheel 9, which meshes with it, to rotate. The worm wheel 9 rotates at the bottom of the rudder bearing seat 1 through the rotating ring 8. The worm wheel 9 forces the guide rod 10 to slide along the corresponding guide groove through the arc-shaped through groove on it. The guide rod 10 drives the corresponding connecting block 6 away from the rudder bearing body 2. The connecting block 6 drives the slide rod 5 to slide on the support block 4. The fixing pin 7 is pulled out from the corresponding fixing hole, quickly releasing the rudder bearing body 2, saving maintenance time and improving efficiency.

[0027] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
