Abstract

This utility model discloses a bearing housing, a bearing housing mounting structure, and a rod end spherical bearing, including a snap-fit ​​base and a bearing mounting part disposed on the snap-fit ​​base. The snap-fit ​​base includes an upper support plate, a lower support plate, and a lateral connecting plate connecting the sides of the upper and lower support plates.

Description

Technical Field

[0001] This utility model relates to the field of rod end joint bearing technology, specifically to a bearing housing, a bearing housing mounting structure, and a rod end joint bearing. Background Technology

[0002] Mounted rod end spherical plain bearings are a type of non-standard rod end spherical plain bearing. They are characterized by a rod end body with a base, which is connected to the opposing component via a locking mechanism, thus securing the entire rod end spherical plain bearing to the opposing component. (See attached image.) Figure 3 The existing seated rod end spherical plain bearing shown has a base (with a connecting flange on the base) fixedly connected to a fixed base plate (the other component) by bolts. The axial load acting on the bearing is ultimately transmitted to the fixed base plate through the rod end body and bolts. At this point, the bolts bear a certain shear stress, presenting a stress state that is relatively unfavorable to the bolts. In some applications where installation space is limited, it is not possible to use larger bolts to alleviate the above stress problem, which may lead to the risk of bolt breakage during long-term use. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bearing housing, which mainly solves the technical problem that the bolts used for fixing existing seated rod end spherical bearings are prone to breakage due to shear stress and bending stress during long-term use.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A bearing housing includes a snap-fit ​​base and a bearing mounting portion disposed on the snap-fit ​​base. The snap-fit ​​base includes an upper support plate, a lower support plate, and a lateral connecting plate connecting the sides of the upper support plate and the lower support plate. A snap-fit ​​groove adapted to the thickness of the fixed base plate to be assembled is formed between the upper support plate and the lower support plate, and a plurality of bolt locking holes arranged coaxially on the upper support plate and the lower support plate, respectively.

[0005] Furthermore, the upper support plate, lower support plate, and side connecting plate are integrally connected to form a snap-fit ​​base structure with snap-fit ​​grooves.

[0006] Furthermore, the cross-section of the snap-fit ​​base has a U-shaped structure.

[0007] Furthermore, the bearing mounting section is located on the upper support plate.

[0008] Furthermore, the snap-fit ​​base and the bearing mounting part are integrally molded structures.

[0009] Furthermore, the lateral connecting plate has set screw holes that communicate with the snap-fit ​​groove between the upper support plate and the lower support plate, and the lower support plate has several set screw holes that communicate with the inside of the snap-fit ​​groove.

[0010] Based on the same inventive concept, this utility model also provides a bearing housing mounting structure, including a fixed base plate, bolts, and the aforementioned bearing housing. The fixed base plate is adapted to be snapped into the snap-fit ​​groove between the upper support plate and the lower support plate, with the upper support plate tightly abutting the upper end face of the fixed base plate and the lower support plate tightly abutting the lower end face of the fixed base plate. A lateral connecting plate is tightly abutting the side end face of the fixed base plate. A through hole corresponding to the bolt locking hole on the support plate and the lower support plate is provided on the fixed base plate. The upper support plate, the lower support plate, and the fixed base plate are locked and fixed by bolts that pass through the upper support plate, the fixed base plate, and the lower support plate in sequence. A set screw that presses against the side end face of the fixed base plate is installed at the set screw hole of the lateral connecting plate.

[0011] Based on the same inventive concept, this utility model also provides a rod end joint bearing, including the above-mentioned bearing housing mounting structure.

[0012] The above technical solution has the following advantages or beneficial effects:

[0013] In the bearing housing, bearing housing mounting structure, and rod end spherical bearing described in this utility model, the snap-fit ​​base includes an upper support plate and a lower support plate, which are integrally connected by a lateral connecting plate, and a snap-fit ​​groove is formed between the upper and lower support plates. In this way, the fixed base plate to be assembled can be fitted into the snap-fit ​​groove. At the same time, the bolt locking holes of the upper and lower support plates can be used to install bolts to lock the snap-fit ​​base and the fixed base plate together. In use, the shear resistance surface of the bolt can be changed from the existing single shear resistance surface to a double shear resistance surface, which greatly improves the shear resistance performance of the bolt and helps to extend its service life.

It is understood that in this embodiment, since the snap-fit ​​base 1 includes an upper support plate 11 and a lower support plate 12, the upper support plate 11 and the lower support plate 12 are integrally connected by a lateral connecting plate 13, and a snap-fit ​​groove is formed between the upper support plate 11 and the lower support plate 12, the fixed base plate 3 to be assembled can be fitted into the snap-fit ​​groove. At the same time, the bolt locking holes of the upper support plate 11 and the lower support plate 12 can be used to install bolts to lock the snap-fit ​​base 1 and the fixed base plate 3 together. When in use, the shear resistance surface of the bolt can be changed from the existing single shear resistance surface to a double shear resistance surface (the upper support plate 11 and the lower support plate 12 form a double shear resistance surface that abuts against the fixed base plate 3), which greatly improves the shear resistance performance of the bolt and helps to improve its service life.

[0024] Please refer to the appendix. Figure 1 Appendix Figure 2In one preferred embodiment, the lateral connecting plate 13 has set screw holes that communicate with the snap-fit ​​groove between the upper support plate 11 and the lower support plate 12, and the lower support plate 12 has several set screw holes that communicate with the interior of the snap-fit ​​groove. In this embodiment, one or more set screw holes can be provided on the lateral connecting plate 13, and the embodiment is not limited to the specific implementation disclosed herein. In use, by installing set screws in the set screw holes of the lateral connecting plate 13 and the set screw holes of the lower support plate 12, the snap-fit ​​base 1 and the fixed base plate 3 can be tightly fitted and fixed, thereby improving the overturning moment of the bearing seat, reducing the bending moment borne by the bolts, and thus improving the shear resistance of the system.
