Description

Technical Field

[0001] The utility model relates to the technical field of gold ornaments, in particular to a gold bearing and a gold ornament. Background Art

[0002] The Chinese jewelry market has very high requirements for the purity of gold jewelry, with the mainstream gold jewelry standard reaching 999% or higher. Due to the limited hardness of pure gold, structural requirements often necessitate the use of lower-purity alloys (such as AU750) or stainless steel. GB11887 explicitly stipulates that accessories with insufficient gold content must be clearly marked and distinguished.

[0003] In the current industry, the rotating structures of pure gold products all use stainless steel bearings or ceramic bearings. However, stainless steel bearings or ceramic bearings affect the purity and actual gold weight of gold jewelry, and there are a series of problems such as cumbersome circulation and difficult recycling. In addition, the cylindrical roller bearing structure of the existing rotating structure in gold jewelry is not compact enough and can bear a low load, which causes wear and pits on the working surface of the contact structure in the bearing structure, thereby reducing the rotational flexibility of the bearing structure and the feed accuracy of the fine mechanism, resulting in a short service life and the need for improvement.

[0004] In view of this, it is necessary to propose further improvements to the current structure. Utility Model Content

[0039] Example 1

[0040] Please refer to Figure 1 The utility model provides a gold bearing, comprising a bearing outer ring 1 made of pure gold, a bearing seat 2, a fixing member 3 and bearing balls 4; wherein the bearing seat 2 is arranged in the bearing outer ring 1, and a plurality of bearing balls 4 are arranged between the bearing outer ring 1 and the bearing seat 2 via the fixing member 3;

[0041] The fixing member 3 is evenly provided with a plurality of positioning grooves 31, and the bearing balls 4 are arranged in the positioning grooves 31;

[0042] The outer diameter of the bearing outer ring 1 is (4mm~12mm)±0.1mm;

[0043] The size range of the bearing ball 4 is (0.36mm~0.97mm)±0.01mm;

[0044] The ratio of the inner diameter to the outer diameter of the bearing outer ring 1 is in the range of 0.75 to 0.88;

[0045] The ratio of the inner diameter to the outer diameter of the fixing member 3 is in the range of 0.81 to 0.89;

[0046] The size ratio of the outer diameter of the bearing outer ring 1 to the outer diameter of the fixing member 3 is in the range of 1.24 to 1.55;

[0047] The size ratio of the inner diameter of the fixing member 3 to the diameter of the bearing seat 2 is in the range of 1.02 to 1.04;

[0048] The ratio of the height of the fixing member 3 to the height of the bearing seat 2 is in the range of 0.8 to 0.88.

[0049] The current jewelry market has very high requirements for the purity of gold jewelry. The mainstream gold jewelry market standard is 999% or higher. However, due to the limited hardness of pure gold, pure gold products with rotating structures often use stainless steel or ceramic bearings, which affects the purity and actual gold weight of the jewelry, leading to problems such as cumbersome distribution and recycling. However, the gold bearings in the embodiments of the present application are made of pure gold as the overall structure, and their practical performance, balanced load-bearing capacity and rotational precision, are comparable to those of stainless steel or ceramic bearings. The pure gold of the gold bearings in the embodiments of the present application can be AU999 or AU9999, thereby ensuring that the overall purity of gold jewelry with rotating structures reaches 99.9% or higher, meeting the national standard for gold jewelry purity testing. This facilitates the sale and market distribution of such gold jewelry with rotating structures, eliminates the need for redundant labels and logos, and facilitates gold recycling and the modification and replacement of old jewelry.

[0050] AU999 and AU9999 are used to indicate gold purity. AU999 indicates a purity of 99.9%, also known as 999-carat gold. This means that for every 1,000 parts of gold, 999 parts are pure gold, with the remaining 1 part possibly containing other metals or impurities. In jewelry, this type of gold is often labeled "999-carat gold," "999 gold," "gold999," "g999," or "AU999." AU9999 indicates a purity of 99.99%, also known as 10,000-carat gold or 49-carat gold. This is a higher purity than AU999, meaning 9,999 parts of pure gold for every 10,000 parts. This high-purity gold is often used in investment products such as gold bars and coins to ensure its value and purity. The main difference between AU999 and AU9999 lies in their purity, with AU9999 having a higher purity.

[0051] In this embodiment, the golden bearing includes a bearing outer ring 1, a bearing seat 2 and a fixing member 3. The bearing seat 2 is arranged in the bearing outer ring 1, and a plurality of bearing balls 4 are rotatably arranged between the bearing seat 2 and the bearing outer ring 1. A plurality of bearing balls 4 are arranged between the bearing seat 2 and the bearing outer ring 1 through the fixing member 3 so that they can rotate relative to each other.

[0052] The outer diameter of the bearing outer ring 1 is (4mm to 12mm) ± 0.1mm, meaning the minimum size is 4mm ± 0.1 and the maximum size is 12mm ± 0.1mm. This is because the size of the bearing outer ring 1 is primarily designed to match the size of gold jewelry, which is neither too large nor too small during design. Gold jewelry is primarily used for decoration. If too small, gold jewelry is difficult to repair and easily lost once damaged, while too large is heavy and inconvenient to wear. Therefore, a bearing outer ring 1 with an outer diameter of (4mm to 12mm) ± 0.1mm is compatible with most gold jewelry.

[0053] Among them, the size range of the bearing ball 4 is (0.36mm~0.97mm)±0.01mm, and the size of the bearing ball 4 in the embodiment of the present application is specifically 0.36mm, and the number of bearing balls 4 is 5. When the size of the entire gold bearing is small, the size of the bearing ball 4 is also small, and the number of bearing balls 4 accommodated is also small. When the size of the entire gold bearing is relatively large, the size of the bearing ball 4 is also large, and the number of bearing balls 4 accommodated is also large, that is, when the size of the bearing ball 4 is 0.36±0.01mm, the number of bearing balls is 10-15; when the size of the bearing ball 4 is 0.97±0.01mm, the number of bearing balls is 5-9.

[0054] The following table shows the dimensions of the outer ring 1, bearing seat 2, fixing part 3 and bearing ball 4 in the gold bearing, as well as the size ratios between them:

[0055]

[0056]

[0057] As can be seen from the table above, the above-mentioned improvements to the size ratio of gold bearings can effectively improve the lubrication performance of gold bearings, reduce the friction coefficient and minimize wear, thereby improving the load-bearing capacity and speed performance. The balanced load-bearing capacity and rotation accuracy of gold bearings at this size ratio are close to those of stainless steel and ceramic bearings in terms of practical performance, ensuring the stability and durability of gold bearings, improving installation accuracy and reducing the risk of damage. This can ensure the stability and safety of gold jewelry using these gold bearings during the swinging process, and improve the process accuracy of gold jewelry production, making the appearance of gold jewelry more beautiful, and also improving the durability and comfort of gold jewelry.

[0058] The inner diameter refers to the diameter of the inner ring, and the outer diameter refers to the diameter of the outer ring.

[0059] Specifically, a fixing part 3 is also sleeved on the bearing seat 2, and a plurality of positioning grooves 31 are provided on the fixing part 3 at intervals and evenly spaced. A bearing ball 4 is provided in each positioning groove 31. The positioning groove 31 plays a positioning role for the bearing ball 4, which can increase the rotation stability of the bearing ball 4 and provide installation and placement space for the bearing ball 4.

[0060] Moreover, the material of all structures in the embodiments of the present application is pure gold, and the pure gold can be AU999 or AU9999.

[0061] Furthermore, a first annular groove 21 is defined on the bearing seat 21 , a sliding ring 22 is embedded in the first annular groove 21 , and the bearing balls 4 are in rolling contact with the sliding ring 22 .

[0062] In the embodiment, a first ring groove 21 is formed in the middle of the bearing seat 21, and the sliding ring 22 is embedded in the first ring groove 21, and the shape of the first ring groove 21 is matched with the shape of the sliding ring 22. Among them, the bearing ball 4 arranged in the positioning groove 31 is in rolling contact with the sliding ring 22, which can make the rolling of the bearing ball 4 more smooth.

[0063] Further, the inner side wall of the bearing outer ring 1 is further provided with a second ring groove 11, and the bearing ball 4 rolls and abuts in the second ring groove 11.

[0064] In the embodiment, the inner side wall of the bearing outer ring 1 is further provided with a second sliding groove 11, and the bearing ball 4 also rolls and abuts in the second ring groove 11. The second ring groove 11 is arranged here, which can increase the rotation stability of the bearing ball 4.

[0065] Embodiment 2

[0066] The bearing seat 21 in the embodiment of the application is provided with a through hole 24, so that the use scene of the gold bearing can be increased, and other structures are the same as those in embodiment 1.

[0067] Among them, the size ratio of the diameter of the through hole 24 on the bearing seat 21 to the diameter of the bearing seat 21 is 0.52-0.63;

[0068] When the diameter of the bearing seat 21 is 2.4mm, the diameter of the through hole 24 is 1.5mm, and the size ratio of the two is 0.63;

[0069] When the diameter of the bearing seat 21 is 3.6mm, the diameter of the through hole 24 is 2.1mm, and the size ratio of the two is 0.58;

[0070] When the diameter of the bearing seat 21 is 4.8mm, the diameter of the through hole 24 is 2.5mm, and the size ratio of the two is 0.52;

[0071] When the diameter of the bearing seat 21 is 6.8mm, the diameter of the through hole 24 is 3.7mm, and the size ratio of the two is 0.55.

[0072] Embodiment 3

[0073] Please refer to Figure 3-4The present invention also provides a gold ornament, which includes a first gold ornament body 5, a first gold rotating body 51 and the gold bearing in Example 1. A first groove is formed on the side of the first gold rotating body 51 close to the gold bearing, and a second groove 511 is formed on the side of the first gold ornament body 5 close to the gold bearing. The two ends of the gold bearing are respectively embedded in the first groove and the second groove 511 to connect the first gold rotating body 51 and the first gold ornament body 5, and a limiting hole 512 is formed in the second groove 511. A limiting member 23 is also provided on the gold bearing, and the limiting member 23 is adapted to be inserted into the limiting hole 512.

[0074] In this embodiment, the gold jewelry of the present application includes a first gold jewelry body 5 and a first gold rotating body 51. The first gold rotating body 51 is rotatably connected to the first gold jewelry body 5 via the gold bearing described in Example 1. Specifically, a second groove 511 and a first groove are respectively defined in the first gold jewelry body 5 and the first gold rotating body 51. The outer ring 1 of the gold bearing is disposed in the first and second grooves 511, thereby connecting the first gold jewelry body 5 and the first gold rotating body 51 via the gold bearing. The gold bearing is rotatable, allowing the first gold rotating body 51 to rotate relative to the first gold jewelry body 5 via the gold bearing.

[0075] Among them, the material of all structures in the gold jewelry in the embodiment of the present application is AU999 or AU9999 pure gold, which can make the overall purity of the gold jewelry with gold bearings reach 99.9% or above 99.9%, which is convenient for the sales and market circulation of gold jewelry, does not require unnecessary labels and logos, and is also conducive to the recycling of gold materials and the modification and replacement of old jewelry.

[0076] Example 4

[0077] Please refer to Figure 5-6 The present invention also provides a gold ornament, which includes a third gold ornament body 6, a third gold rotating body 61, and the gold bearing in Example 1. A third groove is formed on the side of the third gold rotating body 61 close to the gold bearing. A fourth groove 611 is also formed on the side of the third gold ornament body 6 close to the gold bearing. The two ends of the gold bearing are respectively embedded in the third groove and the fourth groove 611 to connect the third gold rotating body 61 and the third gold ornament body 6. A slot 612 is formed in the fourth groove 611. A limiter is also provided on the gold bearing, which is adapted to be inserted into the limit hole 512.

[0078] In this embodiment, the third gold ornament body 6 and the third gold rotating body 61 are rotatably connected via the gold bearing in embodiment 1, which has the same structure as embodiment 3, but the specific patterns on their appearances are different.

[0079] Furthermore, a counterweight is provided on the third gold rotating body 61 , and a gold decorative piece 62 is also provided on the third gold ornament body 6 .

[0080] In this embodiment, the third golden rotating body 61 is provided with a counterweight. Due to gravity, the counterweight always faces the ground, thereby ensuring that a certain graphic of the third golden rotating body 61 remains at a predetermined position, thereby always corresponding with the golden decorative piece 62 on the third golden jewelry body 6. For example, in this embodiment, the specific graphics of the third golden rotating body 61 and the golden decorative piece 62 are both heart-shaped. Under the action of the counterweight, the heart-shaped direction of the third golden rotating body 61 is always directed towards the golden decorative piece 62, thus realizing the specific design significance of the golden jewelry.
