Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a rudder bearing installation structure for marine engineering equipment industry vessels. Background Technology

[0002] In the marine engineering equipment industry, the rudder bearing is a core supporting component of the rudder system. The stability, ease of adjustment, and sealing performance of its installation structure directly affect the smoothness of the rudder system's transmission and navigation safety, and are crucial to the ship's ability to adapt to complex marine conditions. During navigation, ships must withstand complex loads such as wind and wave impacts and hull vibrations, which places extremely high demands on the positioning accuracy and stability of the rudder bearing installation structure. In particular, the rationality of the assembly between the rudder bearing and the deck and mounting base directly affects the rudder shaft's rotational flexibility and the rudder bearing's service life.

[0003] Currently, most existing ship rudder bearing installation structures use fixed installation methods, lacking flexible angle adjustment mechanisms. This makes it difficult to accurately adapt to the installation angle requirements between different ship rudder systems and decks, resulting in high adjustment difficulty and low precision. This can easily lead to misalignment between the rudder shaft and rudder bearing, causing problems such as transmission jamming and accelerated wear. Furthermore, the locking, positioning, and clamping limit functions of existing structures are inadequate. Adjusted mounting seats are prone to angular displacement or loosening due to hull vibrations, making it impossible to maintain a stable installation state over the long term.

[0004] Furthermore, most rudder bearing mounting structures lack effective auxiliary tightening mechanisms, or the tightening mechanisms are not smoothly transmitted and the tightening force is uncontrollable, making it difficult to reliably limit the position of adjusted components, further reducing installation stability. At the same time, the existing structures have inadequate sealing and protection designs, allowing seawater and marine impurities to easily enter the component mating gaps, leading to corrosion and wear of internal gears, bearings, and other components, shortening the service life of the rudder bearing, increasing maintenance costs and frequency, and failing to meet the long-term stable operation requirements of marine engineering equipment vessels. Therefore, there is an urgent need for a rudder bearing mounting structure that can be precisely adjusted, stably limited, and reliably sealed to address the many shortcomings of existing technologies.

[0033] like Figure 7 As shown, the adjustment mechanism 9 includes an adjustment head 91, a second guide hole 92, a second screw 93, a second tightening head 94, and a tightening spherical surface 95. The second guide hole 92 is located inside the upper outer side of the adjustment seat 5. The second screw 93 is movably connected to the center of the second guide hole 92, and the adjustment head 91 is fixedly connected to the top of the second screw 93. The second tightening head 94 is vertically movably connected to the inside of the second guide hole 92.

The tightening spherical surface 95 is provided on the lower outer side of the second tightening head 94, and the bottom of the tightening spherical surface 95 is connected to the top surface of the mounting seat 2.

[0034] The adjustment head 91 has an internal hexagonal hole at the center of its upper side.

[0035] The invention is used in the following ways: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. During installation and adjustment, firstly, according to the installation requirements of the ship's rudder system, the horizontal and tilt angles of the adjusting seat 5 can be precisely adjusted through several adjusting mechanisms 9 around the adjusting seat 5 to ensure the angle between the rudder shaft 81 and the deck 1, thereby ensuring the smoothness of the rudder system transmission. Specifically, during adjustment, the adjusting head 91 (with a hexagonal socket in the upper center that allows for tool insertion and rotation) drives the screw 93 to rotate. The screw 93 engages with the threaded hole in the center of the tightening head 94, driving the tightening head 94 to move vertically within the guide hole 92. The tightening spherical surface 95 on the lower side of the tightening head 94 tightly fits against the top surface of the mounting seat 2. By adjusting... The extension length of the tightening head 94 in the same adjusting mechanism 9 enables precise fine-tuning of the angle of the adjusting seat 5. After adjustment, the locking mechanism 4 further tightens, fixing the position of the adjusting seat 5. At the same time, the adjusting mechanism 9 remains in a tightened state to assist in positioning and prevent the adjusting seat 5 from shifting angle during use. Specifically, during locking, the spherical surface 6 on the upper outer side of the adjusting seat 5 is movably connected to the spherical groove 7 on the upper inner side of the mounting seat 2. The sealing ring 10 between the two fits tightly to achieve sealing protection, preventing seawater and impurities from entering the gap between the two and avoiding corrosion and wear of the spherical surface 6 and the spherical groove 7, which would affect the adjustment flexibility. The upper side of the adjusting seat 5 and the upper side of the mounting seat 2 are fixed and locked around the perimeter by several locking mechanisms 4 to ensure adjustment. After the seat 5 is adjusted to the correct position, it will not shift. At this time, in the locking mechanism 4, the T-shaped nut block 42 engages in the T-shaped guide groove 41 inside the outer side of the mounting seat 2, realizing the installation and positioning of the locking screw 43. The connecting hole 44 inside the upper outer side of the adjusting seat 5 provides an installation channel for the locking screw 43. The outer side of the hemisphere 46 is movably connected to the semi-concave spherical surface 45 on the upper side of the connecting hole 44, which can adapt to the angular shift during the adjustment of the adjusting seat 5, ensuring that the locking screw 43 can always be stably locked, avoiding uneven force on the locking part and loosening. Here, the rudder bearing mechanism 8 is installed in the center of the adjusting seat 5, which realizes the flexible rotation and stable support of the rudder shaft 81, adapting to the steering operation of the ship's rudder system. The convex groove 85 on the upper outer side of the rudder shaft 81 is movable. Connected to the center of the adjusting seat 5, it provides radial positioning for the rudder shaft 81; the fixed cover 82 is fixedly connected to the upper opening of the adjusting seat 5 by several fixing screws 83, providing sealing protection for the upper side of the rudder bearing mechanism 8; the upper thrust ball bearing 84 between the upper side of the groove 85 and the lower side of the fixed cover 82, and the lower thrust ball bearing 86 between the lower side of the groove 85 and the upper interior of the adjusting seat 5, can effectively withstand the axial thrust generated during the rotation of the rudder shaft 81, reduce the axial wear of the rudder shaft 81, and ensure rotational flexibility; several lower bearings 87 between the lower outer side of the rudder shaft 81 and the interior of the adjusting seat 5 can withstand the radial force of the rudder shaft 81, further improving the stability of the rotation of the rudder shaft 81 and preventing the rudder shaft 81 from shaking during rotation;The fixing cover 2 89 is fixedly connected to the lower opening of the adjusting seat 5 by several fixing screws 2 88, providing sealing protection for the lower side of the rudder bearing mechanism 8. At the same time, the sealing ring 2 810 between the inside of the fixing cover 2 89 and the lower exterior of the rudder shaft 81 further enhances the sealing effect, preventing seawater and impurities from entering the interior of the rudder bearing mechanism 8, avoiding rust and wear of the internal bearings and rudder shaft 81, and extending the service life of the rudder bearing mechanism 8. The auxiliary tightening mechanism 3 is designed to tighten and limit the lower side of the adjusting seat 5 after adjustment, ensuring the stability of the adjustment angle. The specific working process is as follows: After the adjusting seat 5 completes the angle adjustment through the adjusting mechanism 9 and is initially locked by the locking mechanism 4, the auxiliary tightening mechanism 3 starts to work. The operator inserts a tool into the hexagonal socket in the center of the outer side of the locking head 341 and rotates the locking head 341 to drive the transmission shaft 342 to rotate synchronously. The transmission gear 343 on the inner side of the transmission shaft 342 rotates accordingly. Since the transmission gear 343 meshes with the transmission gear 344 on the upper side of the transmission shaft 345, it drives the transmission shaft 345 to rotate. The lower transmission gear 346 rotates synchronously. Since transmission gear 346 meshes with transmission gear 447 at the end of screw 32, it ultimately drives screw 32 to rotate within guide hole 33. Screw 32 is threadedly engaged with the threaded hole in the center of clamping head 31, and clamping head 31 is externally movably connected inside guide hole 33. The rotation of screw 32 is converted into movement of clamping head 31 along guide hole 33, causing clamping head 31 to extend towards adjusting seat 5 until its hemispherical end tightly contacts adjusting seat 5. 5. At the corresponding position on the lower outer side; at this time, stop rotating the locking head 341, the transmission mechanism 34 is in the locked positioning state, the screw 32 no longer rotates, and the tightening head 31 maintains the tightening force on the lower side of the adjusting seat 5. Through this tightening and limiting action, the downward displacement or angular loosening of the adjusting seat 5 after adjustment can be effectively limited. In coordination with the locking mechanism 4 and the adjusting mechanism 9, the installation stability of the adjusting seat 5 is further strengthened, and the angular displacement of the adjusting seat 5 due to vibration during ship navigation is avoided, ensuring the stability of the entire rudder bearing installation structure after adjustment.
