Description

Technical Field

[0001] This utility model belongs to the field of marine bearing technology, specifically relating to a locking clamping marine bearing that is easy to install and position. Background Technology

[0002] Ships often operate in complex and ever-changing aquatic environments. Factors such as vibration, impact, and seawater corrosion can significantly affect the working condition and service life of critical components such as bearings. Traditional marine bearings typically suffer from high positioning accuracy requirements, cumbersome installation procedures, and inconvenient disassembly and maintenance during installation. This is especially true in confined or difficult-to-operate ship cabins, where accurate positioning of the bearing housing and alignment with the shaft system are even more challenging. Even slight misalignment during installation can lead to premature bearing wear, abnormal noise, and may even affect the shaft system's transmission efficiency, posing safety hazards. Furthermore, some bearings may experience slight lateral movement or displacement during operation, requiring a reliable locking mechanism to maintain their working position. Therefore, we propose a locking clamping type marine bearing that facilitates easy installation and positioning. Utility Model Content

This addresses the issue raised in the background art that, during the installation of traditional marine bearings in confined or difficult-to-operate ship cabin environments, accurate positioning of the bearing housing and its alignment and fixation with the shaft system are more difficult, leading to premature bearing wear, abnormal noise, reduced shaft transmission efficiency, and safety hazards. Furthermore, some bearings may experience slight movement or displacement during operation, requiring a reliable locking mechanism to maintain their working position.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a locking clamping marine bearing that is easy to install and position, comprising a lower bearing housing and an upper bearing housing. A fixing bolt is rotatably connected to the bottom of the lower bearing housing. An installation hole is formed on the top of the lower bearing housing. Relief grooves are formed on both sides of the top of the lower bearing housing. A lower bushing is snapped into the top of the lower bearing housing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 One embodiment provided by this utility model: A locking clamping marine bearing for easy installation and positioning includes a lower bearing housing 1 and an upper bearing housing 2. A fixing bolt 11 is rotatably connected to the bottom of the lower bearing housing 1. An installation hole 12 is formed on the top of the lower bearing housing 1. Relief grooves 13 are formed on both sides of the top of the lower bearing housing 1. A lower bushing 14 is snapped onto the top of the lower bearing housing 1. An oil filling hole 21 is formed on the top of the upper bearing housing 2. An upper bushing 22 is fixedly connected to the bottom of the upper bearing housing 2. A connecting hole 23 is formed on the top of the upper bushing 22. Rotation grooves 24 are formed on both sides of the top of the upper bearing housing 2. Four sets of fixing blocks 25 are symmetrically fixedly connected. Positioning grooves 3 are provided on the inner sides of the upper bushing 22 and the lower bushing 14, and connecting grooves 31 are provided on the outer sides of the upper bushing 22 and the lower bushing 14. Bearing bodies 4 are installed on the inner sides of the upper bushing 22 and the lower bushing 14. Mounting structures 5 are provided on both sides of the upper bearing seat 2. The mounting structure 5 includes a rotating cylinder 51. Fixing rods 52 are fixedly connected to the front and rear ends of the rotating cylinder 51. A threaded rod 53 is rotatably connected inside the rotating cylinder 51. A limit block 54 is fixedly connected to the bottom of the threaded rod 53, and a pressure block 54 is fixedly connected to the top of the threaded rod 53. A knob 56 is fixedly connected to the top of the plate 55 and the pressure plate 55. Locking sleeves 6 are rotatably connected to the front and rear ends of the upper bushing 22 and the lower bushing 14. An installation structure 5 is provided. The protrusion at the bottom of the lower bushing 14 fits tightly into the mounting hole 12 of the lower bearing seat 1, enabling rapid and precise pre-positioning of the lower bushing 14. Combined with the coordinated movement of the rotating cylinder 51, threaded rod 53, and limiting block 54 within the relief groove 13 in the installation structure 5, the upper bearing seat 2 and the lower bearing seat 1 can be easily aligned and reliably clamped, greatly simplifying the installation and positioning process and improving installation efficiency. For efficiency and precision, an oil injection hole 21, a connecting hole 23, a positioning groove 3, a connecting groove 31, and a locking sleeve 6 are provided. The oil injection hole 21, the connecting groove 31, the connecting hole 23, and the positioning groove 3 form a clear lubrication path to ensure lubrication effect. At the same time, by rotating the locking sleeve 6, the threads at the front and rear ends of the upper bushing 22 and the lower bushing 14 are engaged, which can generate radial locking force to further firmly clamp the upper bushing 22, the lower bushing 14, and the internal bearing body 4, effectively preventing the bearing body 4 from moving under vibration, and improving the stability and reliability of the overall structure.

[0017] Furthermore, the inner surfaces of the upper bearing housing 2 and the lower bearing housing 1 are respectively fitted with the outer surfaces of the upper bushing 22 and the lower bushing 14 to form a tight support fit. The bottom of the lower bushing 14 is fixedly connected with a protrusion, which is inserted into the mounting hole 12 to achieve the initial positioning and radial limit of the lower bushing 14 on the lower bearing housing 1.

[0018] Furthermore, the oil injection hole 21 and the connecting hole 23 are on the same axis to ensure smooth lubrication injection. The connecting hole 23 is connected to the positioning groove 3. The connecting groove 31 is set between the oil injection hole 21 and the connecting hole 23, forming a complete lubrication channel from the oil injection hole 21 to the connecting hole 23 via the connecting groove 31, and finally into the positioning groove 3, which facilitates the supply of oil to the bearing body 4.

[0019] Furthermore, a circular groove is provided between the two sets of fixing blocks 25 on one side, and the fixing rod 52 is rotatably connected in the circular groove. The fixing rod 52 can be rotatably inserted into and connected in the circular groove. A set of rotating cylinders 51 is a rotatable structure between the two sets of fixing blocks 25 on one side, so that the rotating cylinders 51 can rotate relative to the fixing blocks 25 at a certain angle to adapt to the operating angle. The upper part of the threaded rod 53 is rotatably connected in the rotating groove 24, which restricts the radial movement of the threaded rod 53 but allows it to rotate freely.

[0020] Furthermore, the rotating cylinder 51 has a threaded groove inside, and the threaded rod 53 is rotatably connected in the threaded groove. The threaded rod 53 forms a threaded engagement relationship in the threaded groove. Rotating the rotating cylinder 51 can drive the threaded rod 53 to move up and down. The radius of the limiting block 54 is larger than the radius of the threaded rod 53, forming a stop structure. The radius of the limiting block 54 is smaller than the radius of the relief groove 13. The limiting block 54 is slidably connected in the relief groove 13, so that the limiting block 54 can slide smoothly up and down in the relief groove 13, converting the rotational motion of the rotating cylinder 51 into the lifting and lowering movement of the limiting block 54 in the relief groove 13 of the lower bearing seat 1. The radius of the pressure plate 55 is larger than the radius of the threaded rod 53. The pressure plate 55 is made of rubber, which can provide a flexible sealing and clamping force when tightened.

[0021] Furthermore, the bottom of the lower bearing seat 1 and the bottom of the fixing block 25 are provided with threaded grooves, and the fixing bolt 11 is rotatably connected in the threaded grooves to achieve the fixing of the lower bearing seat 1 itself and the final fastening connection of the fixing block 25 relative to the upper bearing seat 2.

[0022] Furthermore, the front and rear ends of the upper bushing 22 and the lower bushing 14 are provided with threads, and the locking sleeve 6 matches the threads. Rotating the locking sleeve 6 can simultaneously engage the threads on the upper bushing 22 and the lower bushing 14, generating a radial locking force to tightly hold the two together, thereby firmly fixing the internal bearing body 4.

[0023] Working principle: During installation, the lower bearing housing 1 is first initially fixed to the ship mounting base with bolts. The protrusion at the bottom of the lower bushing 14 is aligned and inserted into the mounting hole 12 at the top of the lower bearing housing 1, so that the lower bushing 14 is accurately positioned. The bearing body 4 is placed in the positioning groove 3 inside the lower bushing 14. The upper bushing 22, together with the upper bearing housing 2, is placed above the lower bushing 14. The rotating cylinder 51 is raised at a certain angle (by rotating its fixing rod 52 in the circular groove of the fixing block 25) so that it is basically in a vertical state. The lower end of the limiting block 54 is aligned with the corresponding relief groove 13 on the lower bearing seat 1. Holding the knob 56, the entire rotating cylinder 51 rotates around its axis. Since the rotating cylinder 51 has a threaded groove, and the upper part of the threaded rod 53 can only rotate within the rotating groove 24 and cannot move axially, the rotation of the rotating cylinder 51 forces the threaded rod 53, which is threadedly engaged with it, to move downwards along the axis. The limiting block 54 at the lower end of the threaded rod 53 then slides downwards within the relief groove 13, causing the pressure plate 55 to press firmly against the top of the upper bearing seat 2, ultimately pushing the upper bearing seat 2 downwards. Tighten the bolts to ensure a tight fit against the lower bearing housing 1, completing the clamping and accurate positioning connection between the lower bearing housing 1 and the upper bearing housing 2. The fixing bolt 11 passes through the threaded groove 2 at the bottom of the fixing block 25 and screws into the threaded groove 2 at the bottom of the lower bearing housing 1, further locking the position of the fixing block 25 and enhancing the connection strength. After the lower bearing housing 1 and the upper bearing housing 2 are clamped, the upper bushing 22 and the lower bushing 14 are also pressed together. Their internal positioning grooves 3 together form a space to accommodate the bearing body 4. Rotate the locking sleeves 6 at the front and rear ends of the upper bushing 22 and the lower bushing 14. The threads on the inner wall of the locking sleeve 6 engage with the corresponding threads on the outer walls of the upper bushing 22 and the lower bushing 14. When the locking sleeve 6 is tightened, a strong radial contraction force is generated, which forces the upper bushing 22 and the lower bushing 14 to further contract and clamp inward, thereby firmly clamping and fixing the internal bearing body 4 and effectively preventing displacement or movement during operation. When oil is injected, grease is injected from the oil injection hole 21, flows through the connecting groove 31 on the outer side of the upper bushing 22, enters the connecting hole 23, and finally reaches the positioning groove 3 to provide lubrication for the bearing body 4.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
