Description

Technical Field

[0001] The present invention relates to the technical field of bearing installation tools, and in particular to a bearing installation device. Background Art

[0002] During the construction of large ships, the stern tube is a key part of the shafting system. There are two types of stern tube processing techniques: 1. Integral stern tube, where the inner hole processing and front and rear bearing press-fitting are all performed in the processing workshop; 2. Integral stern hub, where the inner hole processing and front and rear bearing press-fitting are all performed during the assembly, slipway, or dock loading stage. When the front and rear bearings are installed in the inner hole of the stern tube, since the inner hole is generally a two- or three-stepped hole, the outer diameter of each step on the outer peripheral surface of the bearing is an interference fit with the stern tube. When the bearing enters the inner hole and reaches the press-fitting position, due to the small gap between the inner hole and the outer peripheral surface of the bearing and the small operating space, burrs are easily generated on the outer peripheral surface of the bearing and the inner hole due to friction. In addition, the narrow space makes it impossible to inspect and handle the burrs. During the bearing press-fitting process, the burrs will gradually increase, increasing the bearing pressing force. If the pressure exceeds the calculated value, the bearing will be damaged.

[0003] Therefore, a bearing mounting device is needed to solve the above problems. Summary of the Invention

[0035] In the process of installing the bearing in the hub, in order to avoid the burr problem caused by friction when the bearing enters the inner hole and prevent the bearing from being damaged, such as Figs. 1-3 As shown, the present invention provides a bearing installation device, which includes a support base plate assembly 1 , a first support roller assembly 3 , a height adjustment assembly 2 and a second support roller assembly 4 .

[0036] The support plate assembly 1 is detachably connected to the shaft hub 200; the first support roller assembly 3 is disposed on the support plate assembly 1, and the first support roller assembly 3 is located in the first stepped hole of the inner hole 210 of the shaft hub 200. The height adjustment assembly 2 is disposed between the support plate assembly 1 and the first support roller assembly 3, and is capable of adjusting the height of the first support roller assembly 3 relative to the support plate assembly 1. The second support roller assembly 4 is disposed at one end of the first support roller assembly 3, and the second support roller assembly 4 is located in the second stepped hole of the inner hole 210, and the aperture of the second stepped hole is smaller than the aperture of the first stepped hole. The bearing mounting device is configured such that the first support roller assembly 3 and the second support roller assembly 4 can cooperate with the oil groove on the outer ring of the bearing 100, so that the bearing 100 is installed along the axial direction of the inner hole 210.

[0037] During the installation process, the height of the first support roller assembly 3 is adjusted using the height adjustment assembly 2. During the installation of the bearing 100, the first support roller assembly 3 and the second support roller assembly 4 can cooperate with the oil groove on the outer ring of the bearing 100, thereby supporting the bearing 100 as it is installed axially along the inner hole 210, preventing the bearing 100 from shaking and facilitating smooth installation of the bearing 100. Furthermore, during the installation process, the first support roller assembly 3 and the second support roller assembly 4 can serve as guides, eliminating burrs that may be generated by friction when the bearing 100 enters the inner hole 210, preventing damage to the bearing 100, and ensuring smooth installation of the bearing 100.

[0038] Furthermore, the support seat plate assembly 1 includes a base plate 11, a support column 12, and a seat plate 13. The support column 12 is fixedly arranged on the base plate 11, and the seat plate 13 is arranged parallel to and spaced apart from the base plate 11. The seat plate 13 is fixedly arranged on the support column 12, and one end of the seat plate 13 can be detachably connected to the shaft hub 200. The height adjustment assembly 2 is arranged between the seat plate 13 and the first support roller assembly 3. Specifically, the seat plate 13 is T-shaped, and a mounting hole 131 is opened on the seat plate 13. The fastener passes through the mounting hole 131 and is screwed to the threaded hole on the shaft hub 200. By fixing the seat plate 13 with the support column 12 and the fastener, the stability of the seat plate 13 can be ensured. By setting the base plate 11 and setting the base plate 11 on the work surface, the contact area can be ensured, thereby ensuring the stability of the seat plate 13.

[0039] Furthermore, the first support roller assembly 3 includes a first support plate 31, on which a plurality of first rollers 32 are rotatably mounted. The axes of the first rollers 32 are perpendicular to the axis of the inner bore 210. The first support plate 31 is spaced parallel to and spaced from the base plate 13. A height adjustment assembly 2 is disposed between the first support plate 31 and the base plate 13. By adjusting the height adjustment assembly 2, the spacing between the first support plate 31 and the base plate 11 can be adjusted, thereby adjusting the height of the first support plate 31. During the installation of the bearing 100, the bearing 100 and the first rollers 32 form a rolling engagement, guiding the movement of the bearing 100 and preventing collision or friction between the bearing 100 and the wall of the inner bore 210.

[0040] Furthermore, the height adjustment assembly 2 includes a plurality of adjustment bolts 21 spaced apart in the vertical direction and threadedly connected to the base plate 13. The first support plate 31 is supported on the ends of the adjustment bolts 21. By rotating the adjustment bolts 21, the extension length of the adjustment bolts 21 relative to the base plate 13 can be adjusted, thereby adjusting the distance between the first support plate 31 and the base plate 13, thereby adjusting the height of the first support plate 31 in the inner hole 210, thereby ensuring that the first roller 32 on the first support plate 31 can effectively engage with the bearing 100.

[0041] Furthermore, the second support roller assembly 4 includes a second support plate 41, on which a plurality of second rollers 42 are rotatably mounted. The axes of the second rollers 42 are perpendicular to the axis of the inner hole 210. The second support plate 41 is fixedly connected to one end of the first support plate 31, and the height of the second rollers 42 is flush with that of the first rollers 32. Specifically, the first support plate 31 and the second support plate 41 are connected by bolts. By adjusting the relative distance between the first support plate 31 and the second support plate 41, the height position of the second support plate 41 in the second stepped hole can be adjusted, thereby ensuring effective cooperation between the second rollers 42 and the bearing 100. By providing the second support roller assembly 4, the bearing 100 can be guided into the second stepped hole, thereby preventing friction between the bearing 100 and the wall of the second stepped hole.

[0042] Furthermore, the bearing installation device includes a centering roller assembly 5 , which can be mounted on the hub 200 and used to adjust the coaxiality between the bearing 100 and the inner bore 210. In this embodiment, two sets of centering roller assemblies 5 are provided. These centering roller assemblies 5 can adjust the coaxiality between the bearing 100 and the inner bore 210, thereby preventing friction between the bearing 100 and the inner bore 210 when the bearing 100 and the inner bore 210 are fitted with a small clearance, ensuring smooth installation.

[0043] Furthermore, the centering roller assembly 5 includes a connecting plate 51, an adjustment support seat 52, an adjustment screw 53, and a centering roller 54. The connecting plate 51 is used to connect to the hub 200. The adjustment support seat 52 is fixedly mounted on the connecting plate 51. The adjustment screw 53 is inserted into the adjustment support seat 52 and is screwed to the adjustment support seat 52. The adjusting screw 53 is rotatably mounted on one end of the adjusting screw 53 that extends relative to the adjustment support seat 52. The axis of the centering roller 54 is perpendicular to the axis of the inner hole 210, and the centering roller 54 can abut against the outer peripheral surface of the bearing 100. During the adjustment process, the position of the centering roller 54 can be adjusted by rotating the adjustment screw 53, thereby adjusting the position of the bearing 100 so that the axis of the bearing 100 coincides with the axis of the inner hole 210. The bearing 100 is then installed into the inner hole 210. During the installation process, the centering roller assembly 5 also serves as a limiter to prevent the bearing 100 from shifting. Since there is sliding friction between the bearing 100 and the centering roller 54 , the friction force can be reduced.

[0044] Furthermore, the bearing mounting device also includes an anti-rotation assembly 6, which can be provided on the hub 200 to prevent the outer ring of the bearing 100 from rotating. The anti-rotation assembly 6 prevents the outer ring of the bearing 100 from rotating relative to the inner ring during the installation of the bearing 100, allowing the bearing 100 to be pushed smoothly into the inner bore 210.

[0045] Furthermore, the anti-rotation assembly 6 includes an adjustment base 61, an anti-rotation support seat 63, and an anti-rotation roller 64. The adjustment base 61 has a wedge block 62, which is disposed on the seat plate 13. The anti-rotation support seat 63 is slidably disposed on the inclined surface of the wedge block 62. The anti-rotation roller 64 is rotatably disposed on the anti-rotation support seat 63. The anti-rotation roller 64 can be in contact with the outer ring surface of the bearing 100. During the movement of the bearing 100, the anti-rotation roller 64 can rotate relative to the bearing 100. By adjusting the position of the anti-rotation support seat 63 on the wedge block 62, the height of the anti-rotation support seat 63 can be adjusted, thereby ensuring that the anti-rotation roller 64 can be in contact with the bearing 100, thereby preventing the outer ring of the bearing 100 from rotating.

[0046] Furthermore, the anti-rotation assembly 6 also includes a position adjustment assembly, which includes a top lock 65 and a position adjustment bolt 66. The position adjustment bolt 66 is threadedly connected to the top lock 65 and abuts against the wedge block 62. The top lock 65 is fixed to the seat plate 13. During adjustment of the anti-rotation support 63, the position adjustment bolt 66 is tightened to push the adjustment base 61 on the seat plate 13, thereby adjusting the anti-rotation support 63. After the position is adjusted to the desired position, the adjustment base 61 is locked in place on the seat plate 13. This arrangement allows for quick adjustment to ensure that the anti-rotation assembly 6 effectively cooperates with the bearing 100.

[0047] The installation process of the bearing 100 in the hub 200 is as follows:

[0048] Hub bearing press-fit;

[0049] Mount the support base plate assembly 1 on the hub 200. Mount the height adjustment assembly 2 on the base plate 13 of the support base plate assembly 1. Mount the first support roller assembly 3 and the second support roller assembly 4 on the height adjustment assembly 2. Adjust the heights of the first support roller assembly 3 and the second support roller assembly 4. Mount two sets of centering roller assemblies on the hub 200, and install the anti-rotation assembly 6 at corresponding positions on the base plate 13.

[0050] Clean the inner bore 210 of the hub 200 and carefully inspect it to ensure there are no hard particles. Then evenly apply lubricant to the inner surface. Use a truck crane or hoist to transfer the bearing 100 to the end face of the hub 200. Adjust the bearing 100 so that its bottom oil groove aligns with the first roller 32. Adjust the hoist so that the bearing 100 lands on the first support roller assembly 3. Adjust the anti-rotation assembly 6 to fit the bearing 100, and then lock the anti-rotation assembly 6 in place.

[0051] Clean the outer circle of the bearing 100, apply lubricating oil, use the centering roller assembly to adjust the axis of the bearing 100 to coincide with the axis of the inner hole 210, and use the hoist to slowly push the bearing 100 into the inner hole 210. During this process, it is necessary to constantly check and adjust the gap between the inner hole 210 and the outer circle of the bearing 100 as needed to ensure that there is no friction between the outer circle of the bearing 100 and the surface of the inner hole 210 during the pushing process of the bearing 100.

[0052] After the bearing 100 reaches the press-fitting position, the entire bearing installation device is removed, the press-fitting tooling is installed, and the hollow oil jack is used for press-fitting.
