Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing retainer technology, and in particular to a bearing retainer structure. Background Technology
[0002] A bearing retainer ring is a mechanical part used to fix the position of a bearing. It is usually installed on the outer or inner ring of the bearing and serves to provide axial positioning and prevent the bearing from moving or falling off. Depending on the application scenario and functional requirements, bearing retainer rings can be designed with flexible options.
[0003] Traditional bearing retaining rings (such as open retaining rings and closed retaining rings) are prone to loosening under high speed, high vibration or impact loads, which can lead to axial displacement or detachment of the bearing and has certain shortcomings. To address this, we propose a bearing retaining ring structure. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bearing retaining ring structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bearing retaining ring structure includes a retaining ring body, an inner ring fixed inside the retaining ring body for engaging the outer ring and shoulder of the bearing, connecting blocks installed at both ends of the retaining ring body, connecting holes formed on the connecting blocks, a sealing gasket and a connecting seat fixed at the bottom of the retaining ring body, a locking plate installed at the bottom of the connecting seat, and a locking tongue fixed on the locking plate.
[0007] Preferably, the inner ring has a chamfer, and the inner ring is precisely installed on the bearing by means of the chamfer.
[0008] Preferably, the number of connecting seats is several groups, and the several groups of connecting seats are located at the bottom of the retaining ring body and are distributed in a circumferential array.
[0009] Preferably, the locking plate has an L-shaped structure, and the locking tongue is fixed to one end of the bottom of the locking plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model features an inner ring on the retaining ring body. The chamfer on the inner ring facilitates bearing installation. During installation, the inner ring securely holds the outer ring and shaft shoulder of the bearing. Furthermore, by incorporating a connecting seat, locking plate, and locking tongue, the locking plate and the bearing shaft groove form a bidirectional self-locking mechanism after installation, further preventing the retaining ring body from loosening. Attached Figure Description
[0012] Figure 1 This is a top view of a bearing retaining ring structure proposed in this utility model;
[0013] Figure 2 for Figure 1 Bottom diagram;
[0014] Figure 3 for Figure 2 Installation diagram of the locking plate.
[0015] In the diagram: 1. Retaining ring body, 2. Inner ring, 3. Connecting block, 4. Connecting hole, 5. Sealing gasket, 6. Connecting seat, 7. Locking plate, 8. Locking tongue. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-3 A bearing retaining ring structure includes a retaining ring body 1, an inner ring 2 fixed inside the retaining ring body 1, the inner ring 2 having a chamfer, and the inner ring 2 being precisely installed on the bearing through the chamfer. The inner ring 2 is used to engage the outer ring of the bearing and the shoulder. Connecting blocks 3 are installed at both ends of the retaining ring body 1, and connecting holes 4 are provided on the connecting blocks 3. A sealing gasket 5 and a connecting seat 6 are fixed at the bottom of the retaining ring body 1. The number of connecting seats 6 is several sets, and the several sets of connecting seats 6 are located at the bottom of the retaining ring body 1 and arranged in a circumferential array. The bottom of the connecting seat 6 is equipped with a locking plate 7, and a locking tongue 8 is fixed on the locking plate 7. The locking plate 7 has an L-shaped structure, and the locking tongue 8 is fixed to one end of the bottom of the inner side of the locking plate 7. By setting an inner ring on the retaining ring body, the chamfer on the inner ring provides convenience for bearing installation. During installation, the inner ring effectively locks the outer ring of the bearing and the shaft shoulder. At the same time, by setting the connecting seat, locking plate and locking tongue, after installation, the locking plate and the shaft groove of the bearing form a two-way self-locking, further preventing the retaining ring body from loosening.
[0018] When installing the retaining ring body 1, it is now flipped to... Figure 2 In the desired state, insert the caliper into the connecting hole 4 and use the caliper to pre-deform the retaining ring body 1. Then, insert it into the bearing shaft groove. A chamfer is provided on the inner ring 2 of the retaining ring body 1, which contacts the outer ring of the bearing and the shaft shoulder. The chamfer achieves bidirectional axial force dispersion and avoids stress concentration. After the pressure on the retaining ring body 1 is removed, the retaining ring body 1 returns to its original shape. The connecting seat 6 drives the locking plate and locking tongue 8 to embed into the shaft groove, forming a bidirectional self-locking with the inner wall of the shaft groove to prevent loosening and further improve the stability of the installation.
[0019] In summary, compared with the prior art, this utility model provides a convenient bearing installation by setting an inner ring on the retaining ring body and utilizing the chamfer on the inner ring. During installation, the inner ring effectively locks the outer ring of the bearing and the shaft shoulder. At the same time, by setting a connecting seat, locking plate and locking tongue, the locking plate and the shaft groove of the bearing form a two-way self-locking after installation, further preventing the retaining ring body from loosening.
[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
