Description

Technical Field

[0001] This utility model relates to the field of retainer assembly mold technology, and in particular to a cylindrical bearing retainer positioning assembly mold. Background Technology

[0002] Bearings typically consist of four parts: inner ring, outer ring, rollers, and cage. The cage further comprises two parts: retaining ring and support. The support of the cage for cylindrical roller bearings is slender and requires a mold for riveting after assembly with the bearing rings and rollers.

[0003] In existing assembly molds, slender pillars are prone to tilting during riveting, leading to failure of retainer assembly. Therefore, the requirements for coaxiality and uniform force distribution are quite strict during assembly, making the assembly difficult and the assembly efficiency of the retainer low.

[0004] Therefore, it is necessary to propose a positioning and assembly mold for cylindrical bearing cages to reduce the assembly difficulty of cages and improve the assembly efficiency of cages. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the support column is prone to tilting when riveting the retainer in the existing assembly mold, resulting in high assembly difficulty and low assembly efficiency. The present invention provides a positioning assembly mold for a cylindrical bearing retainer.

[0006] The technical solution of this utility model is:

[0007] A cylindrical bearing retainer positioning assembly mold includes a support base and a circular positioning element. The positioning element is sleeved on the outside of the support base, and a positioning protrusion is provided on the outside of the positioning element. The positioning protrusion is distributed in a ring along the axis of the positioning element. One end of the positioning protrusion is fixedly connected to the positioning element, and the other end of the positioning protrusion is provided with a support platform. An arc-shaped groove is provided between two adjacent positioning protrusions.

[0008] Furthermore, the support platform is a rectangular plane.

[0009] Furthermore, the diameter of the arc-shaped groove matches the diameter of the bearing roller.

[0010] Furthermore, the width of the limiting protrusion is the same as the width of the positioning component.

[0011] Furthermore, the junction between the positioning protrusion and the arc-shaped groove is chamfered.

[0012] Furthermore, a limiting component is fixedly connected to the inner side of the positioning component, and a limiting groove is opened on the outer side of the support base, with the limiting component located in the limiting groove.

[0013] Furthermore, the number of positioning protrusions on the positioning element is the same as the number of support columns on the bearing retainer.

[0014] This utility model discloses a positioning and assembly mold for a cylindrical bearing retainer. When the retainer is riveted using a press, the support seat and positioning component installed inside the bearing can provide positioning and support for the bearing. In particular, the positioning protrusion on the positioning component extends into the gap between two adjacent rollers and can contact the support column on the retainer through the support platform on it, thereby generating a supporting force on the support column and preventing the support column from tilting due to uneven force during the riveting process. The arc-shaped groove provides space for the rollers, so that the rollers will not interfere with the support column of the retainer when the positioning protrusion supports the support column. Compared with the traditional technology, this technical solution avoids the tilting of the support column during the riveting process, reduces the assembly difficulty, and improves the assembly efficiency.

[0020] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Example 1:

[0022] like Figure 1 and Figure 2As shown, this embodiment provides a positioning and assembly mold for a cylindrical bearing retainer, including a support base 1 and a circular positioning element 2. The positioning element 2 is sleeved on the outside of the support base 1, and a positioning protrusion 3 is provided on the outside of the positioning element 2. The positioning protrusions 3 are distributed in a ring along the axis of the positioning element 2. One end of the positioning protrusion 3 is fixedly connected to the positioning element 2. Preferably, the positioning protrusion 3 and the positioning element 2 are integrally molded by injection molding. The other end of the positioning protrusion 3 is provided with a support platform 4. An arc-shaped groove 5 is provided between two adjacent positioning protrusions 3. Preferably, the support platform 4 is a rectangular plane. Preferably, the diameter of the arc-shaped groove 5 matches the diameter of the bearing roller. Preferably, the width of the limiting protrusion is the same as the width of the positioning element 2. Preferably, the junction of the positioning protrusion 3 and the arc-shaped groove 5 is chamfered. Preferably, the number of positioning protrusions 3 on the positioning element 2 is the same as the number of support columns on the bearing retainer.

[0023] like Figure 3 As shown, when the retainer is riveted using a press, the support seat 1 and the positioning element 2 installed inside the bearing can provide positioning and support for the bearing. In particular, the positioning protrusion 3 on the positioning element 2, through... Figure 3 As can be seen from the cross-section, the positioning protrusion 3 extends into the gap between two adjacent rollers. Through the support platform 4 on it, it can contact the support column on the retainer, thereby generating a supporting force on the support column and preventing the support column from tilting due to uneven force during the riveting process. The arc-shaped groove 5 can provide space for the roller, so that the roller will not interfere when the positioning protrusion 3 supports the support column of the retainer. Compared with the traditional technology, this technical solution avoids the support column tilting during the riveting process, reduces the assembly difficulty, and improves the assembly efficiency.

[0024] Example 2:

[0025] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows: Figure 4 As shown, a limiting member 6 is fixedly connected to the inner side of the positioning member 2. The limiting member 6 and the positioning member 2 are integrally formed by injection molding. A limiting groove 7 is opened on the outer side of the support base 1, and the limiting member 6 is located in the limiting groove 7. The limiting groove 7 and the limiting member 6 can improve the structural stability and prevent relative rotation between the two during the riveting process, thus affecting the riveting effect.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
