Description

Technical Field

[0001] The utility model relates to the technical field of bearing bushes and bearing bush seats, in particular to a bearing bush and a bearing bush seat. Background Art

[0002] The main bearing of the reciprocating piston compressor body is composed of a bearing shell installed between a bearing cover and a bearing seat. The bearing shell consists of an upper and lower half shell. The circular hole surrounded by the bearing cover and the bearing seat is also the bearing shell installation hole. The bearing seat is set on the body.

[0003] The outer side surface of the bearing is connected to the bearing seat, and the oil passage of the bearing seat is inclined, resulting in the oil hole on the bearing body being inclined; since the bearing body has a simple structure and is symmetrical at both ends.

[0004] In the prior art, when aligning a bearing cover with a large deadweight with a bearing seat, a crane is generally used for transportation and alignment. However, when the crane moves the bearing cover up and down, since the steel cable of the crane is evenly wound on the surface of the drum, the position of the steel cable will produce a large deviation during the process of retracting and releasing the steel cable. Therefore, it is easy to cause the bearing cover and the bearing seat to be unable to be aligned due to deflection during movement. In addition, due to its own large deadweight, it will be difficult to control. Similarly, the bearing shell adapted to such a bearing cover and bearing seat also has this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a bearing shell and a bearing shell seat thereof, so as to solve the technical problems mentioned in the above background technology.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Reference Figure 1-Figure 5 The utility model discloses a bearing bushing, comprising an arc-shaped plate 11, wherein the plates 11 are provided with two pieces, wherein first hemispheres 12 are fixedly provided at both ends of one of the plates 11, and first locking grooves 13 are provided at both ends of the other plate 11 at positions corresponding to the first hemisphere 12, and cylindrical grooves 14 are provided at the four corners of the outer arc surfaces of the two plates 11, and the groove walls of the cylindrical grooves 14 are provided with cross-sectional threads 15.

[0026] In this embodiment, when in use, the two plates 11 are buckled together to form a complete ring, so as to achieve the effect of bearing the shaft rod;

[0027] When installing the two plates 11 to each other, first install the plate 11 with the first hemisphere 12 on the upper end of the bearing seat, and make both sides of the plate 11 in a horizontal state, then use a crane to lift the other plate 11 with the first locking groove 13, and make both sides of the plate 11 with the first locking groove 13 face vertically, and the end surface is parallel to the horizontal plane, and then slowly lower the pallet by the crane to align the end surfaces of the two plates 11 to complete the installation of the two plates 11;

[0028] Furthermore, when the end surfaces of the two plates 11 are flush with each other, the first hemisphere 12 can be directly inserted into the first locking groove 13 to complete the mutual fixation of the two plates 11;

[0029] When the end faces of the two plates 11 correspond to each other and the offset distance is less than the radius of the first hemisphere 12, the hoisted plate 11 is directly lowered to the upper end of the fixed plate 11, and the two plates 11 can be directly aligned with each other through the arc surface of the first hemisphere 12 and the groove wall of the first locking groove 13;

[0030] When the end faces of the two plates 11 correspond to each other but the offset distance is greater than the radius of the first hemisphere 12, a thrust is applied to one side of the hoisted plate 11 to cause the hoisted plate 11 to be offset, and the offset distance is gradually reduced until the offset distance is less than the radius of the first hemisphere 12. At this time, the hoisted plate 11 is lowered again, so that the top end of the first hemisphere 12 enters the interior of the first locking groove 13, and then the two plates 11 are aligned with each other through the arc surface of the first hemisphere 12;

[0031] In summary, when the two plates 11 are buckled together, it is only necessary to align the end faces of the two plates 11 with each other and control the offset range of the two plates 11 to be smaller than the radius of the first hemisphere 12, so that the two plates 11 can be quickly aligned during installation to achieve the purpose of easy assembly.

[0032] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the inner annular wall of the plate 11 is provided with an oil groove 16 , and both sides of the outer arc surface of the plate 11 are provided with outer edge grooves 17 .

[0033] In this embodiment, the oil groove 16 can provide a channel for the lubricating oil, ensuring that the lubricating oil can flow to the friction surface as quickly as possible, reducing the direct contact area between the bearing shell and the shaft rod, and reducing friction. The setting of the outer edge groove 17 facilitates the plate 11 to be inserted into the interior of the bearing seat 21 and the bearing cover 22.

[0034] Embodiment 2:

[0035] Reference Figure 1-Figure 5The utility model discloses a bearing seat, which includes the bearing, and the bearing seat includes a bearing seat 21 and a bearing cover 22. The upper end of the bearing seat 21 is provided with an arc-shaped middle groove 211, and the inner groove wall of the arc-shaped middle groove 211 is provided with a first connecting groove 212 at a position corresponding to the cylindrical groove 14. The inner wall of the first connecting groove 212 is provided with a first thread 213, and second hemispheres 214 are fixedly arranged on both sides of the top of the bearing seat 21.

[0036] In this embodiment, the bearing seat 21 and the bearing cover 22 are buckled together to form a bearing seat. When assembling the bearing and the bearing seat, the bearing seat 21 is installed at the position where the shaft needs to be installed, and then the plate 11 with the first hemisphere 12 is lifted by a crane, and the two ends of the plate 11 are facing upward, so that the plate 11 is inserted into the arc-shaped middle groove 211, and the plate 11 with the first locking groove 13 is lifted, and the two ends of the plate 11 are facing downward, and this plate 11 is buckled on the top of the fixed plate 11. When buckling, the offset distance of the two plates 11 is controlled to be smaller than the radius of the first hemisphere 12, and the two plates 11 are closed to each other, and the effect of buckling the two plates 11 to each other is achieved;

[0037] Lift the bearing cover 22 so that both ends of the bearing cover 22 face downward, and slowly lower the bearing cover 22 to assemble the two plates 11 that close the bearing shell. Similarly, control the falling speed and offset distance of the bearing cover 22. When the offset distance is less than the radius of the second hemisphere 214, directly lower the bearing cover 22 to make the bearing cover 22 contact with the top of the bearing seat 21, so as to achieve the purpose of aligning the bearing cover 22 and the bearing seat 21.

[0038] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a second locking groove 221 is provided at the bottom end of the bearing cover 22 at a position corresponding to the second hemisphere 214, a second connecting groove 222 is provided at an inner wall of the bearing cover 22 at a position corresponding to the cylindrical groove 14, and a second thread 223 is provided on the inner wall of the second connecting groove 222.

[0039] In this embodiment, when the two plates 11, the bearing cover 22 and the bearing seat 21 are assembled and closed, the cylindrical grooves 14 and the cross-sectional threads 15 of the two plates 11 are aligned with each other to form an internal thread groove 1, and when the bearing cover 22 and the bearing seat 21 are aligned with each other, the first connecting groove 212 and the second connecting groove 222 are aligned with each other, and the first thread 213 and the second thread 223 are aligned with each other. At this time, the first connecting groove 212, the second connecting groove 222, the first thread 213 and the second thread 223 jointly form an internal thread groove 2. When the bearing composed of the two plates 11 is installed inside the bearing seat composed of the bearing cover 22 and the bearing seat 21, the internal thread groove 1 and the internal thread groove 2 correspond to each other to form a complete positioning hole with an internal thread. At this time, the screw matching the positioning hole is screwed into the interior of the positioning hole. At this time, the installation of the bearing and the bearing seat is completed, thereby achieving the purpose of improving the installation efficiency.

[0040] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the arc-shaped middle groove 211 and the inner sides of the bearing cover 22 are both provided with an epitaxial platform 23 , and the epitaxial platform 23 and the outer edge groove 17 are matched.

[0041] In this embodiment, by providing the epitaxial platform 23 , when the plate 11 and the bearing cover 22 or the bearing seat 21 are connected to each other, the stability of the connection between the plate 11 and the bearing seat 21 can be improved.

[0042] The implementation principle of the above embodiment is as follows: when in use, the bearing seat 21 is first installed at the position where the shaft needs to be installed, and then the plate 11 with the first hemisphere 12 is buckled inside the arc-shaped middle groove 211, and the outer edge grooves 17 on both sides of the plate 11 are engaged with the extension platform 23. At this time, the plate 11 with the first hemisphere 12 and the bearing seat 21 are engaged with each other and fixed;

[0043] Then, the plate 11 with the first locking groove 13 is lifted by a crane, and the plate 11 is transferred to the top of the bearing seat 21, so that the two end planes of the plate 11 are flush with the two end planes of the plate 11 fixed on the bearing seat 21. At this time, the plate 11 is moved downward, and a thrust is applied to it according to the offset of the plate 11, so that the offset distance between the two plates 11 is less than the radius of the first hemisphere 12. At this time, the two plates 11 are in contact with each other, and the first hemisphere 12 is inserted into the first locking groove 13. The inner wall of the first locking groove 13 will contact the outer wall of the first hemisphere 12, and then the two plates 11 are aligned and in contact with each other through the guidance of the first hemisphere 12;

[0044] Similarly, when the bearing cap 22 is installed on the upper end of the bearing seat 21, it is only necessary to control the offset distance of the bearing cap 22 to be smaller than the radius of the second hemisphere 214, thereby effectively improving the installation efficiency between the plates 11 with larger deadweight;

[0045] After the bearing cap 22, the bearing seat 21 and the two plates 11 are installed, the cylindrical groove 14, the first connecting groove 212 and the second connecting groove 222 together form a positioning hole, and the cross-sectional thread 15, the first thread 213 and the second thread 223 together form an internal thread of the inner hole wall of the positioning hole, and then the screw is inserted into the interior of the positioning hole as shown in FIG. Figure 5 At this time, the purpose of fixing the two plates 11, the bearing cover 22 and the bearing seat 21 is achieved.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
