Description

Technical Field

[0001] The invention belongs to the technical field of stern shaft bearing disassembly, and in particular relates to a marine bearing disassembly device and method. Background Art

[0002] During the construction of large, medium and small ships, the installation of the stern tube bow and stern bearings is of utmost importance. Due to the large specifications of marine bearings, interference fit is usually used between the bearing and the main shaft to ensure the reliability of the connection. There are two ways to dismantle bearings: destructive and non-destructive. For example, some factories use special tooling to fix magnetic drills, mill grooves through the garbage trough of the bearing, cut off both sides of the bearing, and then dismantle it. Other factories use air planing to destructively dismantle the bearings, protecting the safety of the main shaft by destroying the bearings; some factories use pullers, hydraulic jacking and other methods to dismantle bearings.

[0003] Due to the large size of marine bearings, the bearing installation position is often narrow, and marine bearings work in harsh marine environments for a long time and are easily damaged by wear, corrosion, etc., so regular disassembly and inspection can timely discover problems, take preventive maintenance, and extend the service life of bearings; at the same time, bearing rolling elements such as balls and rollers will gradually wear and deform over time, and rolling elements need to be replaced regularly to ensure the normal operation of bearings. Since the main shaft of the marine bearing is fixed during the disassembly process, the inner ring of the bearing is also stationary, and in order to ensure the integrity of the bearing, the outer ring of the bearing, the cage and the rolling element cannot change relative position, so the existing marine bearing disassembly device is difficult to meet the integrity of the disassembled bearing.

[0004] Patent document CN115464600A discloses a quick disassembly device for bearings on ships, including a main adjusting rod, a pitch adjusting assembly, a housing, a secondary adjusting rod, a second spur gear, a first rotating shaft, a third spur gear, a first bevel gear, a first mounting tube, a ring groove, a second bevel gear, a mounting seat, a keyway, a limit rod, a push rod, a limit key, an external thread, a second mounting tube, a clamping assembly, a clamping base, a connecting rod, a first ball shaft, an inclined plate and a limit groove. Compared with the existing bearing disassembly device, this patent can achieve centering and avoid the situation where the main shaft is damaged due to local overload. However, the clamping assembly of the patent clamps the chamfer of the bearing, resulting in local force on the outer ring of the bearing, which can easily cause the outer ring of the bearing to rotate or slide upward, and even excessive external force can cause the chamfer of the bearing to deform, destroying the structure of the cage or rolling element, making it difficult to meet the integrity of the disassembled bearing.

[0055] The present invention also provides a method for using a marine bearing disassembly device, the method comprising the following steps:

[0056] S1, connect the two spindle support half sleeves 31 by bolts, at this time the spindle support sleeve assembly 3 is located on the top of the bearing 2 and outside the spindle 1;

[0057] S2, connect the two upper clamping seats 41 by bolts, at this time the spindle support sleeve assembly 3 is clamped inside the upper clamping seat assembly 4, and the positions of the spindle support sleeve assembly 3 and the upper clamping seat assembly 4 are relatively fixed by two adjustment assemblies 5;

[0058] S3, pre-install the rubber gasket 62, the rubber adsorption member 63 and the quick-insert connector 64 in the lower holder 61 to form an integral part, and connect the two integral parts by bolts to form the lower holder assembly 6, and lock the upper holder assembly 4 and the lower holder assembly 6 by bolts, at which time the upper and lower surfaces and the outer surface of the bearing 2 are all abutted;

[0059] S4, start the negative pressure pump to pump negative pressure into the rubber adsorption member 63 through the quick-plug connector 64. After reaching the preset pressure, close the stop valve on the connecting hose connected to the quick-plug connector 64 and stop the operation of the negative pressure pump. At this time, the outer ring of the bearing 2 is further positioned;

[0060] S5, start the transverse telescopic mechanism 7 to telescope back and forth, strike the lifting block 617, so that the bearing 2 has a tendency to move upward on the axis of the main shaft 1, and gradually increase the working stroke of the transverse telescopic mechanism 7;

[0061] S6, when the working stroke of the transverse telescopic mechanism 7 reaches the preset requirement, the transverse telescopic mechanism 7 is kept in the extended state and the movement of the transverse telescopic mechanism 7 is stopped;

[0062] S7, start the vertical telescopic mechanism 9, and stop extending the vertical telescopic mechanism 9 when the extension shaft connecting hole 91 and the through hole of the connecting block 81 are in a coaxial position, and fasten the connecting block assembly 8 and the vertical telescopic mechanism 9 by the connecting screw and the connecting nut of the connecting block assembly 8;

[0063] S8, synchronously start the two vertical telescopic mechanisms 9 to shrink them, and stop the operation of the vertical telescopic mechanisms 9 when the bearing 2 is completely separated from the main shaft 1;

[0064] S9, restore the rubber adsorption member 63 to normal pressure, restore the lateral telescopic mechanism 7 to the initial state, separate the upper clamping seat assembly 4 and the lower clamping seat assembly 6, take out the bearing 2, and inspect it.

[0065] It is not difficult to understand that, since the bearing 2 and the main shaft 1 are connected by interference fit, and the marine bearings work in a harsh marine environment for a long time and are susceptible to damage such as wear and corrosion, the most difficult stage in the bearing disassembly process is the initial relative separation of the bearing 2 and the main shaft 1. The present invention uses the transverse telescopic mechanism 7 to knock and push the bearing 2 so that it obtains an upward movement trend. When the bearing 2 becomes "loose" relative to the main shaft 1, the working stroke of the transverse telescopic mechanism 7 can be adjusted according to the actual situation on site.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The method for using the marine bearing removal device according to any one of claims 4 to 9, characterized in that: The method of use includes the following steps: S1, connecting the two spindle support half sleeves (31) by bolts, at which time the spindle support sleeve assembly (3) is located on top of the bearing (2) and outside the spindle (1); S2, connecting the two upper clamping seats (41) by means of bolts, at which time the spindle support sleeve assembly (3) is clamped inside the upper clamping seat assembly (4), and the positions of the spindle support sleeve assembly (3) and the upper clamping seat assembly (4) are relatively fixed by means of two adjustment assemblies (5); S3, pre-install the rubber gasket (62), the rubber adsorption member (63) and the quick-insert connector (64) in the lower holder (61) to form an integral part, and connect the two integral parts by bolts to form a lower holder assembly (6), and lock the upper holder assembly (4) and the lower holder assembly (6) by bolts, at which time the upper and lower surfaces and the outer surface of the bearing (2) are all in contact; S4, starting the negative pressure pump to draw negative pressure into the rubber adsorption member (63) through the quick-connect connector (64). After reaching a preset pressure, closing the stop valve on the connecting hose connected to the quick-connect connector (64) and stopping the operation of the negative pressure pump. At this time, the outer ring of the bearing (2) is further positioned; S5, start the transverse telescopic mechanism (7) to telescope back and forth, strike the lifting block (617), so that the bearing (2) has a tendency to move upward on the axis of the main shaft (1), and gradually increase the working stroke of the transverse telescopic mechanism (7); S6, when the working stroke of the transverse telescopic mechanism (7) reaches a preset requirement, the transverse telescopic mechanism (7) is kept in an extended state, and the movement of the transverse telescopic mechanism (7) is stopped; S7, start the vertical telescopic mechanism (9), lower it until the extension shaft connection hole (91) and the through hole of the connection block (81) are in a coaxial position and stop, and fasten the connection block assembly (8) and the vertical telescopic mechanism (9) by means of the connection screw and the connection nut of the connection block assembly (8); S8, synchronously starting the two vertical telescopic mechanisms (9) to shrink them, and stopping the operation of the vertical telescopic mechanisms (9) until the bearing (2) is completely separated from the main shaft (1); S9, restore the rubber adsorption member (63) to normal pressure, restore the transverse telescopic mechanism (7) to its initial state, separate the upper clamping seat assembly (4) and the lower clamping seat assembly (6), take out the bearing (2), and inspect it.
