Description

Technical Field

[0001] This utility model relates to the field of rubber bearing technology, specifically a novel rubber bearing device. Background Technology

[0002] Rubber bearings, as core supporting components of mechanical transmission systems, are widely used in automobiles, construction machinery, water pumps, and other fields due to the elastic damping properties, low coefficient of friction, and strong adaptability of rubber materials. They utilize a structure where the inner steel ring is fixed to the shaft and the outer steel ring is fixed to the equipment housing. The relative sliding of the inner and outer rubber rings guides the shaft's rotation, while simultaneously buffering vibration and reducing noise.

[0003] However, during operation, the relative sliding of the inner and outer rubber rings in a rubber bearing generates a significant amount of frictional heat. Since rubber has poor thermal conductivity, this heat easily accumulates internally. High temperatures accelerate rubber aging, reduce mechanical properties, cause lubricant failure, exacerbate wear, severely shorten bearing life, and may even lead to equipment malfunction.

[0004] Existing heat dissipation technologies primarily rely on natural heat dissipation or simple lubricating media for heat conduction, resulting in limited efficiency and insufficient capacity to meet cooling requirements. Some improved solutions employing heat sinks or forced air cooling suffer from poor compatibility between the heat dissipation structure and the bearing, as well as uneven airflow distribution, failing to achieve targeted and efficient heat dissipation. Therefore, developing compact and stable heat dissipation devices for rubber bearings has become a key requirement for improving the reliability and service life of rubber bearings.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a novel rubber bearing device, comprising: an outer steel ring 1, an inner steel ring 2, an outer rubber ring 3 installed on the inner wall of the outer steel ring 1, and an inner rubber ring 4 installed on the inner wall of the inner steel ring 2. It also includes: multiple equidistant first mounting through holes 5 on one side of the outer wall of the outer rubber ring 3; multiple equidistant second mounting through holes 6 on one side of the outer wall of the inner rubber ring 4; a first heat dissipation component 7 installed in the first mounting through holes 5; a second heat dissipation component 8 installed in the second mounting through holes 6; and annular shells 9 installed on both sides of the outer steel ring 1. Multiple equidistant air outlet holes 10 are opened on the outer walls of both annular shells 9, and the same air blowing component 11 is connected to one side of the inner wall of both annular shells 9.

[0017] It should be noted that: the inner steel ring 2 is fixedly installed to the equipment shaft, and the outer steel ring 1 is fixedly installed to the outer wall of the equipment. When the equipment shaft is driven to rotate, it will drive the inner steel ring 2, which is fixed to it, to rotate synchronously, and the inner rubber ring 4 installed on the inner wall of the inner steel ring 2 will rotate together with the inner steel ring 2; the outer steel ring 1 is stationary, and the outer rubber ring 3 on its inner wall remains stationary. Ultimately, a relative sliding is formed between the inner rubber ring 4 and the outer rubber ring 3, realizing the bearing's function of supporting the shaft and guiding its rotation.

[0018] To address the issue of heat generation during operation of the rubber ring, multiple equidistant first mounting through holes 5 are formed on the outer wall of the outer rubber ring 3, and multiple equidistant second mounting through holes 6 are formed on the outer wall of the inner rubber ring 4. A first heat dissipation component 7 and a second heat dissipation component 8 are installed within these holes. The first heat dissipation component 7 directly contacts the outer rubber ring 3, absorbing its internal heat and conducting it outwards; the second heat dissipation component 8 contacts the inner rubber ring 4, similarly absorbing its heat and conducting it outwards, thus completing the heat transfer from the rubber ring to the heat dissipation components.

[0019] Annular shells 9 are installed on both sides of the outer steel ring 1. The inner walls of the two annular shells 9 are connected to the same air blowing assembly 11. When the air blowing assembly 11 is working, it generates airflow and blows the airflow into the two annular shells 9 respectively. Multiple equidistant air outlets 10 on the outer wall of the annular shells 9 blow the airflow out of the shells in a directional manner. The blown airflow directly acts on the two ends of the first heat dissipation assembly 7 and the second heat dissipation assembly 8, accelerating the airflow on the surface of the heat dissipation assembly. The heat dissipated by the heat dissipation assembly is removed through convection heat exchange, and finally the outer rubber ring 3 and the inner rubber ring 4 are cooled.

[0020] In a preferred embodiment, the first heat dissipation component 7 includes a plurality of annularly distributed first heat-conducting rods 701, first ring plates 702 installed at both ends of the first heat-conducting rods 701, and a plurality of equidistantly distributed first heat dissipation fins 703 installed on the outer walls of the two first ring plates 702.

[0021] It should be noted that when the outer rubber ring 3 generates heat, the heat is first transferred to the first heat-conducting rod 701 inserted into the first mounting through hole 5. The first heat-conducting rod 701 transfers the heat to the first ring plates 702 at both ends through heat conduction. The first ring plates 702 disperse the heat to multiple first heat sinks 703 on their outer wall. The first heat sinks 703 increase the heat dissipation efficiency by increasing the contact area with the air. Combined with the airflow blown out by the air outlet 10 of the annular shell 9, the heat is quickly carried away, enhancing the heat dissipation effect of the outer rubber ring 3.

[0022] In a preferred embodiment, the second heat dissipation assembly 8 includes a plurality of annularly distributed second heat-conducting rods 801, second ring plates 802 installed at both ends of the second heat-conducting rods 801, and a plurality of equidistantly distributed second heat dissipation fins 803 installed on the outer walls of the two second ring plates 802.

[0023] It should be noted that: the heat generated by the inner rubber ring 4 during operation is transferred to the second heat-conducting rod 801 in the second mounting through hole 6, and the second heat-conducting rod 801 conducts the heat to the second ring plates 802 at both ends; the second ring plates 802 disperse the heat to multiple second heat sinks 803 on the outer wall, and the second heat sinks 803 accelerate the transfer of heat to the surrounding air by increasing the heat dissipation area; at the same time, the airflow blown out by the air outlet 10 of the annular shell 9 acts on the second heat sinks 803, accelerating convection heat transfer, thereby efficiently removing the heat from the inner rubber ring 4 and achieving the cooling of the inner rubber ring 4.

[0024] In a preferred embodiment, the blower assembly 11 includes a mounting tube 1102 and a fan 1101 mounted on the inner wall of the mounting tube 1102.

[0025] It should be noted that when the fan 1101 is connected to an external power source and started, the blades of the fan 1101 rotate to generate airflow, which enters the mounting tube 1102. The mounting tube 1102 acts as an airflow channel, guiding the airflow generated by the fan 1101 to the inside of the two annular shells 9, providing a stable airflow source for the air outlet 10 of the annular shells 9, thereby providing power for the convective heat dissipation of the first heat dissipation component 7 and the second heat dissipation component 8, and ensuring the airflow circulation of the entire heat dissipation system.

[0026] In a preferred embodiment, the mounting tube 1102 is inverted "Y" shape.

[0027] It should be noted that when the fan 1101 generates airflow, the inverted "Y"-shaped mounting tube 1102 can evenly distribute the single airflow to the two branch ends, so that the airflow can enter the two annular shells 9 synchronously and evenly, avoiding the problem of insufficient heat dissipation of the heat dissipation components on one side due to uneven airflow distribution.

[0028] In a preferred embodiment, the fan 1101 is connected to an external power source via a power cord.

[0029] It should be noted that the fan 1101 is connected to an external power source via a power cord, and the external power source provides a stable power supply to the fan 1101.

[0030] Working principle: The inner steel ring 2 is installed on the equipment shaft, and the outer steel ring 1 is installed on the outer wall of the equipment. When the equipment shaft rotates, it drives the inner steel ring 2 to rotate synchronously. The inner rubber ring 4 on the inner wall of the inner steel ring 2 rotates with it, while the outer rubber ring 3 on the inner wall of the outer steel ring 1 remains stationary. Finally, the inner rubber ring 4 and the outer rubber ring 3 form a relative sliding relationship, realizing the function of supporting the shaft and guiding its rotation.

[0031] To address the heat dissipation issue of the rubber rings, multiple equidistant first mounting through holes 5 are opened on the outer wall of the outer rubber ring 3, and multiple equidistant second mounting through holes 6 are opened on the outer wall of the inner rubber ring 4. A first heat dissipation component 7 is installed in the first mounting through hole 5, and a second heat dissipation component 8 is installed in the second mounting through hole 6. The two heat dissipation components absorb the heat generated by the outer rubber ring 3 and the inner rubber ring 4 respectively and conduct it outward.

[0032] The first heat dissipation component 7 includes multiple annularly distributed first heat-conducting rods 701, first ring plates 702 at both ends, and first heat dissipation fins 703 on the outer wall of the ring plates. The heat from the outer rubber ring 3 is transferred to the first heat-conducting rods 701, conducted through the first heat-conducting rods 701 to the first ring plates 702, and then dispersed by the first ring plates 702 to the first heat dissipation fins 703. The heat dissipation area is increased by the first heat dissipation fins 703, thereby accelerating heat dissipation.

[0033] The second heat dissipation component 8 consists of multiple annularly distributed second heat-conducting rods 801, second ring plates 802 at both ends, and second heat dissipation fins 803 on the outer wall of the ring plates. The heat from the inner rubber ring 4 is transferred to the second heat-conducting rods 801, then conducted to the second ring plates 802, and then dispersed to the second heat dissipation fins 803. The heat dissipation area is expanded by the second heat dissipation fins 803, thereby improving the heat dissipation efficiency.

[0034] The blower assembly 11 includes a mounting tube 1102 and a fan 1101 on its inner wall; the fan 1101 starts after being connected to an external power source, and the airflow generated enters the mounting tube 1102, which guides the airflow to the annular shells 9 on both sides of the outer steel ring 1.

[0035] The outer wall of the annular shell 9 has multiple equidistant air outlets 10; the airflow entering the annular shell 9 is blown out through the air outlets 10 and directly acts on both ends of the first heat dissipation component 7 and the second heat dissipation component 8, accelerating the airflow on the surface of the heat dissipation components, and removing heat through convection heat exchange, ultimately achieving the cooling of the outer rubber ring 3 and the inner rubber ring 4.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
