Abstract
Description
Technical Field
[0001] This utility model relates to a rubber ring, and more particularly to a shock-absorbing through-shaft rubber ring, belonging to the field of rubber ring technology. Background Art
[0002] The rubber ring is suitable for use in the air supply of magnetic levitation air conditioners. Since magnetic levitation air conditioners use the principle of magnetic levitation, they will generate heat and other problems when rotating at high speed.
[0003] The main problem with the rubber rings currently used in the market is that their ends are all sealed, which not only fails to dissipate heat well, but also makes them unsuitable for the needs of machine model improvements due to the special shaft section requiring it to pass through the product. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of poor heat dissipation in the prior art by providing a shock-absorbing through-shaft rubber ring that achieves good heat dissipation and reduces vibration.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a shock-absorbing through-shaft rubber ring, used in conjunction with a metal bracket and a bearing; the rubber ring is a rubber body with a metal-free design; the rubber ring includes a left part and a right part; the left and right parts are externally symmetrical; the center of the rubber ring is a bearing mounting hole, the bearing is installed in the bearing mounting hole, and a fan shaft passes through the center of the bearing; the center of the left part of the rubber ring has a through hole A, which communicates with the bearing mounting hole, and the diameter of the through hole A is smaller than the diameter of the bearing mounting hole; the center of the right part of the rubber ring has a through hole B, and the diameter of the bearing mounting hole is larger than the diameter of the through hole B, which is larger than the diameter of the through hole A.
[0006] The outer opening on the right side of the through hole B is a flared opening. The flared opening is a guide opening used for guiding the bearing during installation.
[0007] There is a slot between the left and right parts. The slot is used for mounting and fixing with the metal bracket.
[0008] The left side of the structure has several evenly distributed fan-shaped grooves A, with reinforcing ribs A between them. The fan-shaped grooves A serve to reduce weight while also absorbing shock. The reinforcing ribs A provide support and damping.
[0009] The right side of the part has several evenly distributed fan-shaped grooves B, with reinforcing ribs B between them. The fan-shaped grooves B serve to reduce weight while also absorbing shock. The reinforcing ribs B provide support and damping.
[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: The through-shaft design perfectly solves the problem of insufficient heat dissipation after high-speed rotation at the shaft end during use. Furthermore, the magnetic levitation fan blades vibrate significantly during high-speed rotation, and the through-shaft design allows for a more stable shaft by appropriately extending the shaft length. The double-sided hollow design not only reduces product weight but also adds reinforcing ribs to the hollow areas, making the product more stable, especially for internal bearing installation. The reinforcing ribs also further enhance shock absorption. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0018] like Figures 1 to 5 As shown, a shock-absorbing through-shaft rubber ring is assembled with a metal bracket (not shown) and a bearing (not shown). The rubber ring is made of rubber and adopts a metal-free design. The rubber ring includes a left part 1 and a right part 2. The left part 1 and the right part 2 are symmetrical on the outside. The center of the inside of the rubber ring is a bearing mounting hole 3, and the bearing is installed in the bearing mounting hole 3. A fan shaft (not shown) passes through the center of the bearing. The center of the left part 1 of the rubber ring has a through hole A 4, which communicates with the bearing mounting hole 3. The diameter of the through hole A 4 is smaller than the diameter of the bearing mounting hole 3. The center of the right part 2 of the rubber ring has a through hole B 5, and the diameter of the bearing mounting hole 3 is larger than the diameter of the through hole B 5, which is larger than the diameter of the through hole A 4.
[0019] The outer opening on the right side of the through hole B5 is a flared opening 6. The flared opening 6 is a guide opening used for guiding the bearing during installation.
[0020] There is a slot 7 between the left part 1 and the right part 2. The slot 7 is used for mounting and fixing with the metal bracket.
[0021] The left side of the left portion 1 has several fan-shaped grooves A8 evenly distributed on its left side, with reinforcing ribs A9 between the fan-shaped grooves A8. The fan-shaped grooves A8 serve to reduce weight while also absorbing shock. The reinforcing ribs A9 provide support and vibration damping.
[0022] The right side of the right portion 2 is evenly provided with several fan-shaped grooves B10, and reinforcing ribs B11 are arranged between the fan-shaped grooves B10. The fan-shaped grooves B10 are used for weight reduction and shock absorption. The reinforcing ribs B11 are used for support and shock absorption.
[0023] The embodiments described above are merely preferred embodiments of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution should be included within the protection scope of this utility model.
