Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco machinery and equipment technology, and in particular to a disassembly tool for a water ring pump support bearing. Background Technology
[0002] Currently, in the tobacco leaf threshing and re-drying process, multiple water ring pumps are needed to vacuum the vacuum rehumidifier. After a period of use, wear on the support bearings of the water ring pump's impeller causes significant vibration, leading to malfunction. In this case, the support bearings of the impeller need to be replaced. However, because the support bearings are mounted on the end cap, and the dimensional deviation between the rolling elements of the support bearing and the bearing positioning step holes on the end cap is small, disassembly using traditional methods like tapping with a copper rod results in low disassembly efficiency. Utility Model Content
[0003] The purpose of this utility model is to provide a disassembly tool for the support bearing of a water ring pump, so as to solve the problem of low disassembly efficiency when using copper rods to strike the bearing for disassembly in the prior art.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] like Figures 1 to 2 As shown, this embodiment provides a disassembly fixture for a water ring pump support bearing. The fixture includes a crossbeam 1, a drive screw 3, a support member 4, and two hook members 2. The crossbeam 1 is arranged radially along the support bearing. The two hook members 2 are slidably fitted onto both ends of the crossbeam 1, moving closer or further apart. The hook members 2 are arranged axially along the support bearing and are used to penetrate the inner ring of the support bearing and hook the rolling elements. The drive screw 3 passes through the crossbeam 1 and is threadedly connected to it. The drive screw 3 is located between the two hook members 2 and is arranged axially along the support bearing. The support member 4 can connect to the sealing cover of the support bearing and is arranged radially along the support bearing. The drive screw 3 can abut against the end of the support member 4 furthest from the support bearing.
[0028] The disassembly fixture for water ring pump support bearings of this invention involves first connecting the support member 4 to the sealing cover of the support bearing. Then, two hook members 2 are inserted into the inner ring of the support bearing, and their relative positions are adjusted to hook the rolling elements of the support bearing. Next, the drive screw 3 is turned so that the end of the drive screw 3 and the support member 4 away from the support bearing abuts. At this point, the crossbeam 1 drives the two hook members 2 to pull the support bearing. Continuing to turn the drive screw 3, the support bearing is removed from the sealing cover. This design eliminates the need for the existing method of disassembly using a copper rod, effectively improving the disassembly efficiency of the support bearing.
[0029] In some embodiments, the crossbeam 1 includes a middle beam 11 and two connecting beams 12 disposed at both ends of the middle beam 11. Two hooks 2 are slidably fitted onto the two connecting beams 12, thereby adjusting the relative position of the two hooks 2. A drive screw 3 passes through the middle beam 11 and is threadedly connected to it, allowing the drive screw 3 to drive the hooks 2 to move axially along the support bearing via the connecting beams 12.
[0030] Specifically, the hook member 2 has a mounting hole 21, wherein the shape of the connecting beam 12 matches the shape of the mounting hole 21, so that the connecting beam 12 can be smoothly passed through the mounting hole 21, and the hook member 2 and the crossbeam 1 can be matched in the axial upper limit of the support bearing.
[0031] In this embodiment, the shape of the mounting hole 21 includes, but is not limited to, a rectangle or a polygon. All of the above shapes can achieve the purpose of upper limit fit in the axial direction of the support bearing, and at the same time can prevent the hook part 2 from rotating.
[0032] In some embodiments, the intermediate beam 11 has a threaded hole 111, through which the drive screw 3 passes and is threadedly engaged with the threaded hole 111. This allows the crossbeam 1 and the hook member 2 to move axially along the support bearing.
[0033] Specifically, the hook component 2 includes an interconnected mounting block 22 and a hook rod 23. The mounting block 22 has a mounting hole 21 for easy insertion of the connecting beam 12; the hook rod 23 can be inserted into the inner ring of the support bearing and hook the rolling elements of the support bearing.
[0034] Specifically, the drive screw 3 includes a threaded rod 31 and a mandrel 32 connected to each other. The threaded rod 31 passes through the crossbeam 1 and is threadedly connected to the crossbeam 1, and abuts against the end of the support member 4 away from the support bearing via the mandrel 32.
[0035] Furthermore, the top head 32 has a tapered guide head 321, and the support member 4 has a guide hole 41, into which the tapered guide head 321 can be inserted. This arrangement can serve as a guide.
[0036] Optionally, the drive screw 3 also includes a polygonal operating post disposed on the threaded rod 31, which, in conjunction with a wrench, rotates the threaded rod 31.
[0037] Specifically, the support member 4 includes a support rod 42 and at least two fasteners 43. The support rod 42 is arranged radially along the support bearing, and the at least two fasteners 43 pass through both ends of the support rod 42 and can be connected to the sealing cover of the support bearing. This arrangement achieves the purpose of connecting the support rod 42 and the sealing cover of the support bearing. The fasteners 43 include, but are not limited to, bolts.
[0038] Furthermore, the support member 4 also includes at least two positioning sleeves 44, which are positioned on the side of the support rod 42 facing the support bearing. Fasteners 43 pass through the support rod 42 and the positioning sleeves 44 in sequence and can connect to the sealing cover of the support bearing. This arrangement allows the positioning sleeves 44 to serve a positioning and guiding function, improving installation efficiency. The at least two positioning sleeves 44 and the at least two fasteners 43 are arranged in a one-to-one correspondence.
[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
