Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring retaining ring technology, and more specifically, to a spring retaining ring for resisting axial impact. Background Technology
[0002] A spring retainer ring is an elastic mechanical part used for axial positioning. It is typically made of spring steel or stainless steel and has an open ring structure. It engages with a shaft or bore through elastic deformation, using its own elastic force to generate radial pressure, thus fixing the position of rotating components such as bearings and gears. It also buffers vibration and compensates for assembly clearances. Common types include shaft retainers (E-type retainers) and bore retainers (C-type retainers), widely used in the automotive, aerospace, and industrial equipment industries.
[0003] The shaft retaining ring and the hole retaining ring have different orientations for the mounting protrusions at the open end. The shaft retaining ring faces outward, while the hole retaining ring faces inward. The two are not interchangeable, and different molds are required for processing, which increases the cost of use. In addition, the spring retaining ring is subjected to axial force as a whole, and the workpiece is in contact with the end face of the spring retaining ring, resulting in poor uniformity of force distribution. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a spring retaining ring that resists axial impact, so as to solve the problems in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution;
[0006] A spring retainer ring resistant to axial impact includes a retainer ring body, which is integrally formed and has an opening. The retainer ring body includes two ends at the opening, and each of the two ends is provided with a symmetrically distributed inner mounting groove and an outer mounting groove. The two end faces of the retainer ring body are respectively set as a flat end and a conical end, and the conical end is used to contact and block the workpiece.
[0007] As a further description of the above technical solution: the inner ring thickness of the retaining ring body is two-thirds of the outer ring thickness.
[0008] As a further description of the above technical solution: the angle between the inclined plane and the vertical plane at the conical end of the retaining ring body is °.
[0009] As a further description of the above technical solution: each of the two opposite ends is provided with an arc-shaped stress block.
[0010] As a further description of the above technical solution: the retaining ring body has a non-uniform width structure.
[0011] Compared with existing technologies, the advantages of this utility model are:
[0012] This solution improves the axial impact resistance of the retaining ring body through the conical end design, and utilizes the combination design of the inner and outer mounting grooves at the end to achieve dual-purpose functionality. This results in a device with stronger overall axial impact resistance and the advantage of dual-purpose functionality. Attached Figure Description

[0019] 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;
[0020] Please see Figure 1-4 In this utility model, the spring retainer ring for resisting axial impact includes a retainer ring body 1, which is integrally formed and has an opening. The retainer ring body 1 includes two ends 2 at the opening. Each end 2 is provided with a symmetrically distributed inner mounting groove 3 and an outer mounting groove 4. The two end faces of the retainer ring body 1 are respectively set as a flat end 5 and a conical end 6, and the conical end 6 is used to contact and block the workpiece.
[0021] In this invention, the inner mounting groove 3 and outer mounting groove 4 on the two ends 2 of the retaining ring body 1 allow the retaining ring body 1 to be expanded and installed into the outer end groove of the shaft when used as a shaft retaining ring, with the outer mounting groove 4 serving as the connection point. When used as a hole retaining ring, the inner mounting groove 3 is used to retract the retaining ring body 1, allowing it to be installed in the groove within the hole, achieving dual-purpose functionality and better compatibility. Simultaneously, the conical end 6 contacts and blocks the workpiece, causing the workpiece to generate axial thrust, which is evenly radially dispersed by the conical end 6. This not only makes the force on the retaining ring body 1 more uniform, but also, because the conical end 6... The axial force is uniformly dispersed radially, so that part of the axial force on the retaining ring body 1 is deflected and dispersed radially towards the hole wall. This improves the axial impact resistance when used as a retaining ring for holes, thus enabling the device to have stronger overall axial impact resistance and achieve the advantages of dual-purpose use. This solves the problems in the prior art where the shaft retaining ring faces outward and the hole retaining ring faces inward, making them incompatible and requiring different molds for processing, increasing the cost of use. In addition, the spring retaining ring is subjected to axial force as a whole, and the workpiece is in contact with the end face of the spring retaining ring, resulting in poor force uniformity.
[0022] Please see Figure 4 The inner ring thickness of the retaining ring body 1 is two-thirds of the outer ring thickness.
[0023] In this invention, the inner ring thickness of the retaining ring body 1 is two-thirds of the outer ring thickness, forming an inward-curving inclined surface on one side of the conical end 6. When used as a retaining ring for holes, this design achieves radial dispersion of axial impact and improves the resistance to axial impact.
[0024] Please see Figure 4 The angle between the inclined plane and the vertical plane of the conical end 6 of the retaining ring body 1 is 20°.
[0025] In this invention, the angle between the inclined plane and the vertical plane of the conical end 6 of the retaining ring body 1 is 20°, which can maintain the component force of the conical end 6 and ensure the structural strength of the retaining ring body 1.
[0026] Please see Figure 3 Among them, each of the two ends 2 is provided with an arc-shaped stress block 21 at the opposite end.
[0027] In this invention, the arc-shaped stress block 21 allows the two ends 2 to be inserted into the two inner mounting slots 3 during installation. The tool applies force, causing the two ends 2 to move closer together, which causes the retaining ring body 1 to shrink and deform, thus achieving installation inside the hole. When the inner wall of the inner mounting slot 3 is subjected to force, the arc-shaped stress block 21 can enhance the deformation resistance of the side of the inner mounting slot 3 near the outside of the end 2. When the tool applies force to the inner mounting slot 3 and the outer mounting slot 4, the structure is stable, the structural strength is improved, and deformation under force is avoided.
[0028] Please see Figure 2 Among them, the retaining ring body 1 has a non-uniform width structure.
[0029] In this invention, the non-uniform width structure of the retaining ring body 1 significantly improves the axial load bearing capacity, and makes the inner surface of the retaining ring body 1 form a more comprehensive contact surface with the bottom of the external groove of the installed shaft, resulting in a more uniform distribution of compressive stress.
[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
