Abstract
Description
Technical Field
[0001] This invention belongs to the field of marine bearing housing manufacturing, and particularly relates to a separable and adjustable marine bearing housing. Background Technology
[0002] Bearings are crucial components in modern machinery, primarily supporting rotating parts and ensuring their rotational accuracy. In marine applications, various drive shafts are often required for rotational drive, necessitating extensive use of bearing housings. Marine bearing housings typically operate under high-intensity conditions. The drive shaft is usually fixedly connected to a support ring on the bearing housing, which is then rotatably mounted on the housing. The support ring can be rotatably mounted on the housing via rolling balls. This prolonged high-intensity operation leads to friction between the support ring and the rolling balls, as well as between the rolling balls and the housing. This friction generates high temperatures, causing localized deformation of the components and shortening the lifespan of the support ring, requiring periodic replacement. Existing structural assembly methods do not facilitate convenient replacement of the support ring. Furthermore, thermal deformation of the support ring causes unstable rotation of the drive shaft, affecting normal operation. Therefore, upgrading the existing structure is necessary to reduce wear, mitigate the drawbacks of high-temperature thermal deformation, and extend the structure's service life. Summary of the Invention
[0003] To address the shortcomings of the prior art, the present invention provides a separable and adjustable marine bearing housing that avoids prolonged friction and wear, high-temperature deformation, reduces losses, increases service life, and facilitates drive control.
[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:
[0005] A separable and adjustable marine bearing housing includes a positioning base, a separation positioning mechanism, and a refueling cylinder. The upper side of the positioning base has a through-type positioning channel. Two separation positioning mechanisms are installed on the positioning channel, respectively positioned front and rear on the positioning base. Each separation positioning mechanism includes an upper moving plate, a lower moving plate, a rolling ball, a support ring, a power mechanism, and a controller. The upper and lower moving plates are mounted opposite each other on the positioning channel. The power mechanism is installed on the side of the positioning base and controls the movement of the upper and lower moving plates. Multiple rolling balls are evenly installed on the inner sides of the upper and lower moving plates; the support ring is installed between two pairs of upper and lower moving plates, and the upper and lower moving plates move relative to each other, causing the rolling balls to abut or separate from the support ring; the controller is installed on the positioning base, and the controller drives and controls two power mechanisms, so that the power mechanisms control the upper and lower moving plates to move relative to each other, so that the two separation positioning mechanisms alternately clamp and position the support ring; two oiling cylinders are installed at the upper end of the positioning base, and the oiling cylinders introduce lubricating oil into the separation positioning mechanisms respectively.
[0006] Furthermore, a rotation limiting groove is provided on the inner side of both the upper and lower moving plates; a rolling ball is rotatably engaged in each of the rotation limiting grooves.
[0007] Furthermore, it also includes an upper telescopic oil guide pipe, a side telescopic oil guide pipe, and an oil inlet pipe; the interior of the upper movable plate is provided with an upper guide groove, the two ends of which extend to the two ends of the upper movable plate; the interior of the lower movable plate is provided with a lower guide groove, the two ends of which extend to the two ends of the lower movable plate; both ends of the upper guide groove and both ends of the lower guide groove are connected to the side telescopic oil guide pipe; the outer middle of the rotation limiting groove of the upper movable plate is connected to the upper guide groove through an oil guide hole, and the outer middle of the rotation limiting groove of the lower movable plate is connected to the lower guide groove through an oil guide hole; an oil inlet pipe is installed in the middle of the upper end of the upper movable plate, the lower end of which is connected to the upper guide groove, and the lower side of the refueling cylinder is connected to the oil inlet pipe through the upper telescopic oil guide pipe.
[0008] Furthermore, the volume of the rolling ball located in the rotation limiting groove is two-thirds, and one-third of the rolling ball protrudes outward from the rotation limiting groove.
[0009] Furthermore, the outer perimeter of the support ring is provided with two annular rotating grooves, which are distributed on both sides of the support ring; the support ring is limited by contact with multiple rolling balls through the annular rotating grooves.
[0010] Furthermore, the outer sides of the upper and lower moving plates are respectively provided with moving blocks; the two sides of the positioning seat are provided with moving tracks; the outer sides of the upper and lower moving plates are respectively slidably mounted on the moving tracks by the moving blocks, the power mechanism is a drive motor, and the upper side of the power mechanism passes through the moving track through a lead screw and is threadedly connected to two moving blocks, so that the two moving blocks slide relative to each other up and down.
[0011] Furthermore, both the upper and lower movable plates have an arc-shaped structure, and the upper and lower movable plates are joined together to form a clamp structure.
[0012] Furthermore, the lower moving plate, rolling ball, and support ring are all made of high-strength alloy steel.
[0013] The beneficial effects of this invention are as follows:
[0014] 1. This invention transforms the traditional integrated structure into a separate structure. The separation of the upper and lower moving plates causes the rolling ball to abut against the upper and lower outer sides of the support ring, thus facilitating assembly and disassembly. Simultaneously, this invention uses a controller to drive two power mechanisms to work collaboratively. One power mechanism controls the relative movement of a pair of upper and lower moving plates, causing the rolling ball to abut against the upper and lower outer sides of the support ring. Meanwhile, the other pair of upper and lower moving plates causes the rolling ball to separate from the upper and lower outer sides of the support ring. After a period of operation, the previously separated pair of upper and lower moving plates is driven to bring the rolling ball abutting against the support ring, while the previously abutting pair is driven to separate the rolling ball from the support ring. This periodic replacement allows the two separation and positioning mechanisms to alternately clamp and position the support ring, changing the rotating abutment position on the support ring. This significantly reduces high-temperature thermal deformation and high-intensity friction caused by prolonged operation at the same location on the support ring.
[0015] 2. The present invention features a separate upper and lower movable plate. To facilitate the integrated introduction of lubricating oil, the upper movable plate has an upper guide groove inside, and the lower movable plate has a lower guide groove inside. Both ends of the upper and lower guide grooves are connected by a side telescopic oil guide pipe. Thus, lubricating oil is injected through the oil inlet pipe and can be delivered into the rotation limiting groove through the upper guide groove, the side telescopic oil guide pipe, the lower guide groove, and the oil guide hole, achieving convenient integrated oil guiding.

[0027] like Figures 1 to 8 As shown, to facilitate integrated oil guiding and improve lubrication performance, it further includes an upper telescopic oil guide pipe 4, a side telescopic oil guide pipe 5, and an oil inlet pipe 6; the upper movable plate 21 has an upper guide groove 211 inside, with both ends of the upper guide groove 211 extending to the edges of both ends of the upper movable plate 21; the lower movable plate 22 has a lower guide groove 221 inside, with both ends of the lower guide groove 221 extending to the edges of both ends of the lower movable plate 22; the two ends of the upper guide groove 211 and... Both ends of the lower guide groove 221 are connected to the side telescopic oil guide pipe 5; the outer middle of the rotation limiting groove 26 of the upper moving plate 21 is connected to the upper guide groove 211 through the oil guide hole 7, and the outer middle of the rotation limiting groove 26 of the lower moving plate 22 is connected to the lower guide groove 221 through the oil guide hole 7; an oil inlet pipe 6 is installed in the middle of the upper end of the upper moving plate 21, and the lower end of the oil inlet pipe 6 is connected to the upper guide groove 211; the lower side of the oil filling cylinder 3 is connected to the oil inlet pipe 6 through the upper telescopic oil guide pipe 4.
[0028] like Figures 1 to 8As shown, in order to improve the installation stability of the rolling ball 23, the volume of the rolling ball 23 located in the rotation limiting groove 26 is two-thirds, and one-third of the rolling ball 23 protrudes outward from the rotation limiting groove 26.
[0029] like Figures 1 to 8 As shown, in order to facilitate the rotational assembly of the support ring 24, two annular rotation slots 249 are provided around the outer perimeter of the support ring 24, and the two annular rotation slots 249 are distributed on both sides of the support ring 24; the support ring 24 is abutted and limited by the annular rotation slots 249 and the multiple rolling balls 23.
[0030] like Figures 1 to 8 As shown, to facilitate the relative sliding of the upper moving plate 21 and the lower moving plate 22, moving blocks 27 are respectively provided on the outer sides of the upper moving plate 21 and the lower moving plate 22; moving tracks 12 are provided on both sides of the positioning base 1; the outer sides of the upper moving plate 21 and the lower moving plate 22 are respectively slidably mounted on the moving tracks 12 via the moving blocks 27; the power mechanism 25 is a drive motor; the upper side of the power mechanism 25 is threaded through the moving track 12 via a lead screw 251 and connected to the two moving blocks 27, allowing the two moving blocks 27 to slide relative to each other.

After a period of operation, the previously separated pair of upper moving plates 21 and lower moving plates 22 are driven to make the rolling ball 23 abut against the support ring 24, while the previously abutting pair of upper moving plates 21 and lower moving plates 22 are driven to make the rolling ball 23 separate from the support ring 24. This is done periodically, so that the two separation positioning mechanisms 2 alternately clamp and position the support ring 24, changing the working position of the rotating abutment on the support ring 24. This greatly reduces the high temperature thermal deformation and high intensity friction of the same position on the support ring 24 during long-term operation.

To facilitate the integrated introduction of lubricating oil, the upper moving plate 21 has an upper guide groove 211 inside, and the lower moving plate 22 has a lower guide groove 221 inside. Both ends of the upper guide groove 211 and the lower guide groove 221 are connected by a side telescopic oil guide pipe 5. Lubricating oil is injected through the oil inlet pipe 6 and can be delivered to the rotation limiting groove 26 through the upper guide groove 211, the side telescopic oil guide pipe 5, the lower guide groove 221, and the oil guide hole 7, thus achieving convenient integrated oil guiding.
