Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly equipment, in particular to a sliding bearing disassembler. Background Art

[0002] Reciprocating compressors are often used in the petrochemical industry. In order to ensure normal production, reciprocating compressors need to be regularly inspected and repaired. The front and rear sliding bearings of the reciprocating compressor crankshaft are often severely worn. The bearing seat needs to be removed and the sliding bearings in the bearing seat need to be replaced. Figure 3 The figure is a schematic diagram of the structure of the sliding bearing 16 and the bearing seat 17. The outer wall of the sliding bearing 16 and the inner wall of the bearing seat 17 are tightly matched. In actual operation, there is no special tool to disassemble and install the sliding bearing 16. A hammer is used to knock the sliding bearing 16 to remove the worn sliding bearing 16 from the bearing seat 17 or to drive the replaced sliding bearing 16 into the bearing seat 17. Not only is the efficiency of disassembly and installation low, but it is also easy to damage the bearing seat 17 or the replaced sliding bearing 16. Utility Model Content

[0003] The purpose of the utility model is to design a sliding bearing disassembler so as to solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A sliding bearing disassembler comprises a support plate, a screw rod, a bolt and a pull plate, wherein a first through hole is provided in the middle of the support plate, second through holes are provided on both sides of the support plate symmetrically about the middle part, a third through hole is provided in the center of the pull plate, one side of the support plate is a locking surface, and the other side is a supporting surface, one end of the screw rod is threadedly connected with a first locking nut, and the other end passes through the first through hole and the third through hole in sequence from the locking surface to the supporting surface, the bolt passes through the second through hole from the locking surface to the supporting surface, a positioning nut is threadedly connected to the screw rod, the positioning nut contacts with a side of the pull plate away from the support plate, a second locking nut is threadedly connected to the bolt, and supporting feet are provided on both sides of the supporting surface of the support plate symmetrically about the middle part.

[0006] Furthermore, a torsion handle is fixedly connected to a side of the first locking nut away from the support plate.

[0007] Furthermore, a sliding washer is provided between the first locking nut and the locking surface.

[0008] Furthermore, a first soft pad is attached to a surface of the pull plate close to the support plate.

[0009] Furthermore, a second soft pad is attached to the bottom of the supporting foot and a side of the second locking nut close to the supporting plate.

[0010] The beneficial effects of the utility model are:

[0011] The support foot of the support plate is brought into contact with the bearing seat, and the support plate is then fixed to the bearing seat by bolts and a second locking nut. The pull plate is then brought into contact with the worn sliding bearing or the replaced sliding bearing. The screw on the pull plate is then passed through the sliding bearing and the support plate in sequence. The support plate is used as a support point, and the screw is moved by tightening the first locking nut, so that the screw pulls the pull plate, and the pull plate pulls the worn sliding bearing out of the bearing seat or the pull plate pulls the replaced sliding bearing into the bearing seat. This not only improves the efficiency of disassembly and installation, but also avoids damage to the bearing seat or the replaced sliding bearing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] like Figure 1-3 As shown, a sliding bearing disassembler comprises a support plate 1, a screw rod 2, a bolt 3 and a pull plate 4. A first through hole 5 is provided in the middle of the support plate 1, and second through holes 6 are provided on both sides of the support plate 1 symmetrically about the middle thereof. A third through hole 7 is provided in the center of the pull plate 4. One side of the support plate 1 is a locking surface, and the other side is a supporting surface. One end of the screw rod 2 is threadedly connected with a first locking nut 8, and the other end passes through the first through hole 5 and the third through hole 7 in sequence from the locking surface to the supporting surface. The first locking nut 8 is fixedly connected with a twist handle 12 on the side away from the support plate 1. By rotating the twist handle 12, the first locking nut 8 is driven to rotate, so that the screw rod 2 can be moved; a sliding screw nut 8 is provided between the first locking nut 8 and the locking surface. The gasket 13 reduces friction and facilitates the rotation of the first locking nut 8; the bolt 3 passes through the second through hole 6 from the locking surface to the supporting surface, and a positioning nut 9 is threadedly connected to the screw rod 2. The positioning nut 9 contacts the side of the pull plate 4 away from the supporting plate 1, and a first soft pad 14 is affixed to the side of the pull plate 4 close to the supporting plate 1 to prevent the pull plate 4 from causing wear to the sliding bearing 16; a second locking nut 10 is threadedly connected to the bolt 3, and supporting feet 11 are provided on both sides of the supporting surface of the supporting plate 1 symmetrically about the middle thereof, and a second soft pad 15 is affixed to the bottom of the supporting foot 11 and the side of the second locking nut 10 close to the supporting plate 1 to prevent the supporting foot 11 and the second locking nut 10 from causing wear to the bearing seat 17.

[0022] Working principle:

[0023] like Figure 1-4 As shown, when the worn sliding bearing 16 needs to be disassembled, first make the supporting foot 11 of the supporting plate 1 contact with the side of the bearing seat 17 provided with an annular recess, then pass the bolt 3 through the second through hole 6 and the bearing screw hole 18 in sequence, and then tighten the second locking nut 10 on the bolt 3 to fix the support plate 1 on the bearing seat 17, then make the side of the pull plate 4 with the first soft pad 14 contact with the sliding bearing 16, and then use the screw rod 2 to pass through the third through hole 7, the inner hole of the sliding bearing 16 and the first through hole 5 in sequence, and then screw the first locking nut 8 and the positioning nut 9 on both sides of the screw rod 2 respectively, with the support plate 1 as the support point, and then tighten the first locking nut 8 by turning the twist handle 12, so that the screw rod 2 can move upward, and the screw rod 2 will drive the pull plate 4 to move in the direction close to the support plate 1, and the pull plate 4 will pull the worn sliding bearing 16 out of the bearing seat 17.

[0024] like Figure 1-3As shown in Figures 5 and 6, when the replaced sliding bearing 16 needs to be installed, first make the supporting foot 11 of the supporting plate 1 contact with the side of the bearing seat 17 away from the bearing seat 17 provided with an annular recess, then pass the bolt 3 through the second through hole 6 and the bearing screw hole 18 in sequence, and then tighten the second locking nut 10 on the bolt 3 to fix the support plate 1 on the bearing seat 17, then make the side of the pull plate 4 with the first soft pad 14 contact with the sliding bearing 16, and then use the screw rod 2 to pass through the third through hole 7, the inner hole of the sliding bearing 16 and the first through hole 5 in sequence, and then screw the first locking nut 8 and the positioning nut 9 on both sides of the screw rod 2 respectively, with the support plate 1 as the supporting point, and then tighten the first locking nut 8 by turning the twist handle 12 so that the screw rod 2 can move upward, and the screw rod 2 will drive the pull plate 4 to move in the direction close to the support plate 1, and the pull plate 4 will pull the replaced sliding bearing 16 into the bearing seat 17.
