"In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive of other embodiments.

[0023] Embodiment 1

[0024] Reference Figures 1-4 For the first embodiment of the present application, the embodiment provides a riveting structure of a speed reducer support, the riveting structure of the speed reducer support comprises a main tooth shaft 101, a clamping groove 101-1 is formed on the main tooth shaft 101, a first sheet-shaped plate 102 is arranged in the clamping groove 101-1, the clamping groove 101-1 limits the first sheet-shaped plate 102 from being separated from one side of the main tooth shaft 101, a second sheet-shaped plate 103 is arranged on one side of the first sheet-shaped plate 102, and a tooth groove corresponding to the main tooth shaft 101 is arranged between the first sheet-shaped plate 102 and the second sheet-shaped plate 103. When installing, the teeth need to be aligned.

[0025] A recess 101-2 is formed on the main tooth shaft 101, and a clamping ring 104 is arranged in the recess 101-2. Through the arrangement of the clamping ring 104 and the recess 101-2, after the clamping ring 104 is placed, the clamping ring 104 preliminarily limits the first sheet-shaped plate 102, limits the first sheet-shaped plate 102 from being separated from the other side of the main tooth shaft 101, and then the second sheet-shaped plate 103 is sleeved on the outside of the main tooth shaft 101. At this time, the stamping riveting process is carried out from the side of the second sheet-shaped plate 103 away from the first sheet-shaped plate 102, so as to fix the second sheet-shaped plate 103 and the main tooth shaft 101, thereby fixing the first sheet-shaped plate 102 and the main tooth shaft 101.

[0026] The applied pressure makes the second sheet-shaped plate 103 deform to generate a groove capable of accommodating the clamping ring 104, and under the action of the pressure, the clamping ring 104 will also deform, become thin and long, and tightly engage with the recess 101-2, so as to fix the position of the first sheet-shaped plate 102. The clamping ring 104 will further hinder the separation of the first sheet-shaped plate 102 and the main tooth shaft 101.

[0027] The first sheet-shaped plate 102 is provided with a guide groove 102-1, and a pin column 105 is inserted into the guide groove 102-1, so as to connect and fix the first sheet-shaped plate 102 and the second sheet-shaped plate 103, the number of the pin column 105 is three, the three pin columns 105 are fixed with the first sheet-shaped plate 102 and the second sheet-shaped plate 103 by stamping and riveting, so that the first sheet-shaped plate 102 and the second sheet-shaped plate 103 form an integral whole, which is the prior art, and the working principle is clear to those skilled in the art.

[0028] During installation, the first sheet-shaped plate 102 is placed in the clamping groove 101-1, then the clamping ring 104 is placed in the recess 101-2, then the second sheet-shaped plate 103 is sleeved on the main tooth shaft 101, and then the three pin columns 105 are placed in the guide groove 102-1, and then stamping is performed at the same time, the three pin columns 105 make the first sheet-shaped plate 102 and the second sheet-shaped plate 103 form an integral whole and are fixed with each other, and the part of the main tooth shaft 101 close to the second sheet-shaped plate 103 is also stamped and riveted, the clamping ring 104 is deformed and cooperates with the recess 101-2, so that the first sheet-shaped plate 102 and the main tooth shaft 101 are fixedly connected more stably, and the stability of the connection between the two sheet-shaped plates and the main tooth shaft 101 is ensured.

[0029] Embodiment 2

[0030] Reference Figures 1-6 As a second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0031] Specifically, the material of the clamping ring 104 is spring steel, the spring steel material has a high elastic limit, a high fatigue strength, and sufficient toughness and plasticity, and when impact load or accidental overload is borne, the spring steel can have a certain deformation capacity without brittle fracture.

[0032] Specifically, the clamping ring 104 has an opening, the opening angle is 40 degrees, the clamping ring 104 is C-shaped, and the opening is arranged to facilitate the installation of the clamping ring 104, and the opening enables the clamping ring 104 to be elastically deformed when an external force is applied, thereby reducing the opening angle, so that more parts of the clamping ring 104 can be clamped with the recess 101-2.

[0033] Specifically, the radius of the clamping ring 104 is 10-12 mm.

[0034] Specifically, the cross-sectional radius of the clamping ring 104 is 0.3-0.5 mm.

[0035] Specifically, the groove 101-2 is slightly larger than the cross-sectional diameter of the collar 104, so as to ensure that the collar 104 can be placed in the groove 101-2, and after the placement of the collar 104 is completed, the outer ring thereof will protrude from the groove 101-2, so that in the subsequent stamping and riveting process, the collar 104 is deformed under the pressure and fully adheres to the inner wall of the groove 101-2, thereby limiting the movement of the first sheet-shaped plate 102 and preventing it from being separated from the main tooth shaft 101.

[0036] Specifically, the second sheet-shaped plate 103 is also provided with a guide groove 102-1 corresponding to the pin column 105, and when the first sheet-shaped plate 102 and the second sheet-shaped plate 103 are installed, the guide grooves 102-1 of the two should be overlapped.

[0037] In use, the first sheet-shaped plate 102 is first placed in the clamping groove 101-1, then the collar 104 is placed in the groove 101-2, and then the second sheet-shaped plate 103 is sleeved on the main tooth shaft 101, and then the three pin columns 105 are placed in the guide grooves 102-1. The clamping groove 101-1 will limit the first sheet-shaped plate 102 from being separated from one side of the main tooth shaft 101, and after the placement of the collar 104, the collar 104 will preliminarily limit the first sheet-shaped plate 102 from being separated from the other side of the main tooth shaft 101.

[0038] Then the pin column 105 and the end of the main tooth shaft 101 close to the second sheet-shaped plate 103 are simultaneously stamped, and the three pin columns 105 are deformed to form the first sheet-shaped plate 102 and the second sheet-shaped plate 103 as a whole, thereby fixing the two.

[0039] The part of the main tooth shaft 101 close to the second sheet-shaped plate 103 will also be simultaneously stamped and riveted, and the pressure applied will cause the second sheet-shaped plate 103 to deform and form a groove capable of accommodating the collar 104. Under the action of the pressure, the collar 104 will also deform, become thinner and longer, and tightly engage with the groove 101-2, so as to fix the position of the first sheet-shaped plate 102. The collar 104 further hinders the separation of the first sheet-shaped plate 102 from the main tooth shaft 101, and cooperates with the stamping and riveting process on one side of the main tooth shaft 101, so as to more stably fix the connection between the first sheet-shaped plate 102 and the main tooth shaft 101, thereby improving the stability of the connection between the two sheet-shaped plates and the main tooth shaft 101.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
