DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-10 The present invention is further described with examples:

[0038] like Figure 1-10As shown, a bearing and a bearing seat include: a bearing seat 1, which is formed by splicing and fixing two seat bodies 11, and has a cavity inside for installing components; a bearing 2 arranged inside the bearing seat 1, whose inner ring is used to be fixed to an external rotating shaft; and an oil storage tank 3, installed on the top of the bearing seat 1; a lubrication component 4, installed between the bearing seat 1 and the oil storage tank 3, and used to transport the lubricating oil in the oil storage tank 3 to the bearing 2; a heat dissipation component 5, installed inside the bearing seat 1, its hot end contacts the bearing 2 to absorb heat, and its cold end extends to the outside of the bearing seat 1; an energy conversion part 6, which contacts the cold end of the heat dissipation component 5, and is used to convert the heat energy conducted by the heat dissipation component 5 into mechanical energy for driving the lubrication component 4 to operate. It is a Stirling engine drive structure and belongs to the prior art.

[0039] Specifically, the heat generated by the operation of the bearing 2 is efficiently conducted away through the heat dissipation component 5, ensuring that it operates within a safe temperature range, significantly improving the service life and working stability of the bearing 2; at the same time, the conducted heat energy is conducted to the energy conversion unit 6 and converted into mechanical energy, directly driving the lubrication component 4 to operate, thereby achieving: closed-loop utilization of thermal energy and mechanical energy: utilizing the waste heat of the bearing 2 to drive the lubrication system, reducing external energy consumption; coordinated optimization of the operating environment: forced lubrication and temperature control are simultaneously enhanced to reduce friction losses; significant energy-saving benefits: recovered heat energy replaces traditional electric / hydraulic lubrication power sources, reducing overall energy consumption.

[0040] The heat dissipation assembly 5 includes a heat-conducting seat 51 fixedly connected to the inner bottom wall of the bearing seat 1. A mounting port is formed on the front of the heat-conducting seat 51, and the outer ring of the bearing 2 is fixedly connected to the inner wall of the mounting port of the heat-conducting seat 51. A heat pipe 52 is fixedly connected to the surface of the heat-conducting seat 51. The condensation section of the heat pipe 52 extends to the outside of the bearing seat 1. The heat pipe 52 is used to transfer the heat generated by the operation of the bearing 2 to the outside to reduce the temperature of the bearing 2. The heat generated by the operation of the bearing 2 is transferred to the heat-conducting seat 51, and the heat-conducting seat 51 transfers the heat to the evaporation section of the heat pipe 52. The working fluid in the heat pipe 52 vaporizes and flows to the condensation section, liquefies and releases heat in the condensation section, and the liquefied working fluid flows back to the evaporation section through the micropores on the inner wall of the heat pipe 52 to complete the cycle.

[0041] The condensation section of the heat pipe 52 is extended to form a first branch 521 and a second branch 522 for diverting the vaporized working medium. The first branch 521 is equipped with a first heat conduction mechanism 53, which conducts heat energy to the energy conversion unit 6. The energy conversion unit 6 converts this part of heat into mechanical energy for driving the lubricating component 4. The second branch 522 is equipped with a second heat conduction mechanism 54, which conducts heat energy to the oil storage tank 3 to preheat the lubricating oil to reduce its viscosity and improve the fluidity of the lubricating oil. It is suitable for lubrication when the bearing 2 rotates at a low speed. It can quickly fill the microscopic gaps in the friction pair with stronger capillary penetration and surface tension to form a continuous boundary oil film to avoid direct contact between the metal and the oil. Contact, a valve group 55 is provided between the second branch 522 and the second heat conduction mechanism 54, and the valve group 55 automatically closes when the speed of the bearing 2 reaches a preset threshold to cut off the heat flow to the second heat conduction mechanism 54. When the bearing 2 reaches the preset threshold, that is, the bearing 2 runs at a higher speed, the heat flow to the second heat conduction mechanism 54 is cut off to keep the lubricating oil in the oil tank 3 at a higher viscosity. The high-viscosity oil forms an elastic oil film in the raceway contact area to avoid being thrown out. At the same time, all the heat flow flows to the first heat conduction mechanism 53, increasing the converted mechanical energy, improving the power of the lubrication component 4, outputting a higher oil pressure, ensuring sufficient oil supply in the raceway contact area, and thus improving the reliability of the oil film under high-speed conditions.

[0042] The first heat conduction mechanism 53 includes a first heat conducting pipe body 531 fixedly connected to and in communication with the top of the first branch 521. A heat conducting sleeve 532 is fixedly connected to the surface of the first heat conducting pipe body 531. A first heat conducting rod 533 is fixedly connected to the surface of the heat conducting sleeve 532. A heat conducting pipe 534 is fixedly connected to the end of the first heat conducting rod 533. The heat conducting pipe 534 is sleeved on the heating end of the energy conversion unit 6. A plurality of fins 535 are fixedly connected to the surface of the heat conducting sleeve 532. After the gaseous working medium enters the first heat conducting pipe body 531 and contacts the low-temperature pipe wall, it condenses and releases latent heat. The heat conducting sleeve 532 absorbs the latent heat and transfers a portion of the heat to the first heat conducting rod 533. The first heat conducting rod 533 transfers the heat to the heat conducting pipe 534. The heat conducting pipe 534 transfers the heat to the heating end of the energy conversion unit 6 to heat it. At the same time, the heat conducting sleeve 532 transfers another portion of the heat to the fins 535 for heat dissipation, thereby increasing the condensation speed of the gaseous working medium and ensuring safety.

[0043] The second heat conduction mechanism 54 includes a second heat-conducting pipe body 541 fixedly connected to and communicated with the outlet end of the valve group 55. A second heat-conducting rod 542 is fixedly connected to the surface of the second heat-conducting pipe body 541. The second heat-conducting rod 542 extends into the interior of the oil storage tank 3. After the gaseous working medium enters the second heat-conducting pipe body 541 and contacts the low-temperature pipe wall, it condenses and releases latent heat. The second heat-conducting rod 542 absorbs the latent heat and transfers the heat to the oil storage tank 3, thereby preheating the lubricating oil and improving its fluidity.

[0044] The valve group 55 includes an outer shell 551 fixedly connected to and communicated with the top of the second branch 522. The outer shell 551 has a spherical inner cavity. A bimetallic strip 552 is fixedly connected to the top of the inner wall of the outer shell 551. A connecting rod 553 is fixedly connected to the middle of the bimetallic strip 552. A valve flap 554 is fixedly connected to the bottom end of the connecting rod 553. The contour of the valve flap 554 is adapted to the surface of the spherical inner cavity of the outer shell 551.

[0045] The bimetallic strip 552 is configured such that when the temperature rises to a level corresponding to the speed of the bearing 2 reaching a preset threshold, it deforms, driving the connecting rod 553 and the valve flap 554 to move downward, so that the valve flap 554 forms a sealed fit with the surface of the spherical inner cavity of the housing 551 to block the fluid passage. Under normal circumstances, the valve flap 554 is located in the middle of the spherical inner cavity of the housing 551, and the diameter of the valve flap 554 is smaller than the inner diameter of the spherical inner cavity at this position, so that a passage is formed between the surface of the valve flap 554 and the inner wall of the spherical inner cavity. This passage is used for heat to flow to the second heat-conducting pipe body 541. Compared with the first branch 521, due to the presence of the valve group 55, its passage is smaller, and the heat flow entering the second heat-conducting pipe body 541 is smaller, so that most of the heat is used to drive the lubrication system to ensure its reliability.

[0046] The bottom of the valve disc 554 is integrally formed with an extension column 555 having a diameter equal to the inner diameter of the second branch 522, which is used to coaxially cooperate with the inner wall of the second branch 522. The surface of the extension column 555 is provided with a drainage groove 556 along the circumference. The top of the valve disc 554 is formed with an inverted cone-shaped groove 557 for collecting the condensed and liquefied working medium. The cone top area of ​​the groove 557 is provided with a capillary hole 558. The capillary hole 558 extends radially and penetrates the side wall of the valve disc 554, so that one end thereof is connected to the groove. The conical top of 557 is connected to the drain groove 556 at the other end. A sealing ring 559 is fixedly connected to the surface of the extended column 555. When the valve group 55 is closed, the inner wall of the second heat-conducting pipe body 541 falls into the groove 557 and then enters the capillary hole 558. After flowing from the capillary hole 558 to the drain groove 556, it directly contacts the inner wall of the second branch 522 of the heat pipe 52. It then flows back to the evaporation section through the micropores on the inner wall of the heat pipe 52, ensuring that the working medium can flow back after liquefaction, thereby ensuring the normal operation of the heat pipe 52.

[0047] The inner wall of the mounting port of the heat-conducting seat 51 is fixedly connected with a ring-shaped heat-conducting block 56, and the end of the inner ring of the bearing 2 is fixedly connected with a heat-conducting ring 21. The surface of the heat-conducting ring 21 is in thermal conductivity with the inner wall of the heat-conducting block 56. The surface of the heat-conducting block 56 is provided with a micropore array, and a heat-conducting medium 57 is provided in the micropore array. The heat generated by the rotation of the inner ring of the bearing 2 is transferred to the heat-conducting ring 21, and then transferred to the heat-conducting medium 57 by the heat-conducting ring 21. The heat-conducting medium 57 is transferred to the heat-conducting block 56, and the heat-conducting block 56 is transferred to the heat-conducting seat 51 to absorb the heat of the inner ring. At the same time, the heat-conducting seat 51 absorbs the heat of the outer ring, thereby improving the cooling effect on the bearing 2 and ensuring that sufficient heat is converted into mechanical energy. Preferably, the heat-conducting medium 57 is made by encapsulating paraffin into the pores of metal foam.

[0048] A partition 31 is fixedly connected to the inner wall of the oil storage tank 3, which divides the inner cavity of the oil storage tank 3 into a lubricating oil chamber 32 at the top and a water storage chamber 33 at the bottom. The water storage chamber 33 is a closed space filled with cooling water. One end of the second heat conducting rod 542 extends into the interior of the water storage chamber 33 and exchanges heat with the cooling water. The partition 31 is made of metal material and is used to transfer the heat of the heated cooling water in the water storage chamber 33 to the lubricating oil chamber 32 to preheat the lubricating oil therein, which has the effect of reducing the risk of thermal shock and local overheating. The top of the oil storage tank 3 is detachably connected to a tank cover 34.

[0049] The lubrication assembly 4 includes a bracket 41 fixedly connected to the back of the bearing seat 1, and a lubrication pump 42 is fixedly connected to the bracket 41. The oil inlet end of the lubrication pump 42 is fixedly connected to an oil inlet pipe 43, which extends to the inside of the oil storage tank 3 and passes through the upper surface of the partition 31. The oil outlet end of the lubrication pump 42 is fixedly connected to an oil outlet pipe 44, and one end of the oil outlet pipe 44 passes through the outer ring of the bearing 2 for supplying oil to the inside of the bearing 2. The drive shaft of the lubrication pump 42 is fixedly connected to the output end of the energy conversion part 6. After the heating end of the energy conversion part is heated, its output end makes a circular motion, driving the drive shaft of the lubrication pump 42 to rotate, thereby making the lubrication pump 42 work and injecting lubricating oil into the interior of the bearing 2, wherein the outer walls of the oil inlet pipe 43 and the oil outlet pipe 44 are provided with heat insulation material.

[0050] In this embodiment, the oil storage tank 3 and the energy conversion unit 6 are both supported by a bracket 41. At the same time, all heat-conducting components, such as the first heat-conducting pipe body 531, the second heat-conducting pipe body 541, the heat-conducting sleeve 532, the heat-conducting seat 51, the first heat-conducting rod 533, the second heat-conducting rod 542, etc., are made of heat-conducting materials, such as aluminum alloy, copper alloy, etc. Preferably, a heat-conducting layer, such as a silicone grease heat-conducting layer, can be provided between the contact surfaces of the heat-conducting components.

[0051] Working Principle: During the operation of the bearing and bearing seat, the inner ring of the bearing 2 rotates and generates heat. The heat of the outer ring of the bearing 2 is directly transferred to the heat-conducting seat 51. The heat of the inner ring of the bearing 2 is transferred to the heat-conducting ring 21, which is then transferred to the heat-conducting medium 57. The heat-conducting medium 57 is then transferred to the heat-conducting block 56, and then to the heat-conducting seat 51. The working fluid in the evaporation section of the heat pipe 52 absorbs the heat from the heat-conducting seat 51 and vaporizes and flows to the condensation section.

[0052] When the inner ring of the bearing 2 rotates at a low speed, the heat generated is relatively low, and the temperature of the gasified working medium is not enough to bend the bimetallic strip 552. At this time, the valve flap 554 is located in the middle of the spherical inner cavity of the shell 551. A passage is formed between the surface of the valve flap 554 and the inner wall of the spherical inner cavity. A small amount of heat flow flows to the second heat-conducting pipe body 541 through the passage. The gaseous working medium enters the second heat-conducting pipe body 541 and contacts the low-temperature pipe wall, condenses and releases latent heat. The second heat-conducting rod 542 absorbs the latent heat and transfers the heat to the cooling water in the water storage chamber 33 to perform heat exchange, thereby heating the cooling water. The heat of the heated cooling water is transferred to the lubricating oil chamber 32 through the partition 31, preheating the lubricating oil and improving its fluidity. At the same time, most of the gaseous working medium enters the first heat-conducting pipe body 531 and contacts the low-temperature pipe wall, condenses and releases latent heat. The heat-conducting sleeve 532 absorbs the latent heat. 32 transfers part of the heat to the fins 535 for heat dissipation, thereby increasing the condensation speed of the gaseous working medium and ensuring safety, and transfers the other part of the heat to the first heat-conducting rod 533, which transfers the heat to the heat-conducting tube 534, which transfers the heat to the heating end of the energy conversion unit 6 to heat it. After the heating end of the energy conversion unit is heated, its output end makes a circular motion, driving the drive shaft of the lubrication pump 42 to rotate, so that the lubrication pump 42 works and injects highly fluid lubricating oil into the interior of the bearing 2. With stronger capillary penetration and surface tension, it quickly fills the microscopic gaps in the friction pair, forming a continuous boundary oil film to avoid direct metal contact. The highly fluid lubricating oil can ensure that the lubrication pump 42 can inject the lubricating oil into the interior of the bearing 2 when the bearing 2 rotates at a low speed and generates a small oil pressure.

[0053] When the high-speed rotation of the inner ring of the bearing 2 reaches a preset threshold, the gaseous medium flowing into the second branch 522 causes the bimetallic strip 552 to bend and deform due to the heat, driving the connecting rod 553 and the valve flap 554 downward, so that the valve flap 554 forms a seal with the spherical inner surface of the housing 551, thereby blocking the fluid passage. At this time, the heat flow to the second heat conduction mechanism 54 is cut off, so that the lubricating oil in the oil reservoir 3 maintains a high viscosity. The entire heat flow flows to the first heat conduction mechanism 53, increasing the converted mechanical energy, improving the power of the lubrication assembly 4, and outputting a higher oil pressure to ensure sufficient oil supply in the raceway contact area. The lubrication pump 42 injects the high-viscosity lubricating oil into the bearing 2, forming an elastic oil film in the raceway contact area to prevent it from being thrown out, thereby improving the reliability of the oil film under high-speed operating conditions.

[0054] The bearing and the bearing seat conduct the thermal energy to the energy conversion unit 6 to convert it into mechanical energy, directly driving the lubrication component 4 to operate, thereby reducing the overall energy consumption.
