Description
Technical Field
[0001] The utility model relates to the technical field of oil baffle ring devices, in particular to an oil baffle ring heat dissipation structure. Background Art
[0002] Oil retaining rings are generally used in places where there must be oil but not too much oil, and where excess oil must be retained to prevent outflow and leakage. They are installed on rotating shafts and rotate synchronously with the shafts. The rotors of steam turbines and gas turbines are supported and positioned by bearings installed in bearing boxes. During operation, each bearing needs to be fully lubricated and cooled, so a large amount of lubricating oil must be introduced into each bearing box. The lubricating oil is in a flowing and splashing state in the bearing box. Since the rotor needs to pass through the bearing box, an oil retaining ring needs to be installed between the bearing box and the rotor to prevent the lubricating oil from leaking out of the bearing box, so as to avoid fire and loss of lubricating oil.
[0003] An oil retaining ring according to patent publication number CN202561003U comprises an oil retaining ring body and an oil retaining ring, wherein the oil retaining ring body is provided with an oil retaining ring, and the oil retaining ring is provided with an oil collecting hole; an oil collector connected to the oil collecting hole is provided outside the oil retaining ring; the oil collector is connected to the oil retaining ring by a threaded connection; the outer circumferential surface of the oil retaining ring is conical; the outer end surface diameter of the oil retaining ring is larger than the diameter of the oil retaining ring body, but when the device is in use, due to its integrated structure, it occupies a large area during storage and transportation, and is inconvenient to carry and transport, and the device has poor heat dissipation. During the operation of the motor, the rotor at its end will generate a large amount of heat, which is transferred to the rotating shaft, so that the lubricating oil in contact with the rotating shaft leaks out due to the increase in temperature and the decrease in viscosity, thereby causing oil leakage. If the oil leakage is not discovered in time, the motor where the rotating shaft is located will have the consequence of increased temperature and burning.
[0004] In view of this, we propose an oil baffle ring heat dissipation structure. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0026] See also Figures 1 to 4 , the utility model provides a technical solution:
[0027] A heat dissipation structure of an oil baffle ring comprises an efficient heat dissipation oil baffle ring main body 1, a connecting component 2 is installed on the inner side of the efficient heat dissipation oil baffle ring main body 1, an assembling plate 22 is fixedly installed on the front end of the connecting component 2, a connecting guide groove 1 21 is opened on the right side of the assembling plate 22, a connecting guide groove 23 is opened on the left side of the assembling plate 22, a fitting groove 24 is fitted and connected at the front end of the assembling plate 22, an inner contact plate 26 is installed inside the fitting groove 24, a heat dissipation component 3 is opened on the side of the assembling plate 22, a locking plate 1 25 is fixedly installed on the side of the fitting groove 24, and a limiting seat 27 is installed on the end of the inner contact plate 26.
[0028] It should be added that a connecting component 2 is installed inside the main body 1 of the efficient heat dissipation oil deflector ring. When the oil deflector ring is transported, its connection is easy to disassemble, which can save a lot of space and is easy to carry. When the oil deflector ring needs to be used, the end of the upper assembly plate 22 is docked to the opening of the upper fitting groove 24, and the side connecting guide groove 23 and connecting guide groove 1 21 of the assembly plate 22 are matched and locked with the locking plate 1 25 inside the fitting groove 24. The convex plates on both sides of the assembly plate 22 are matched with the grooves on both sides of the fitting groove 24 for guiding, and the limit seat 27 limits the docked assembly plate 22 to avoid the docking position from shifting, so as to facilitate the storage and transportation of the oil deflector ring.
[0029] As a preferred embodiment of the present invention, a surrounding condensation belt 31 is installed on the inner side of the heat dissipation component 3, a surrounding condensation belt 2 33 is installed on the side of the surrounding condensation belt 1 31, an outer wall air vent 32 is provided on the surface of the heat dissipation component 3, a thermal conductive silicone paste 34 is provided on the inner side of the heat dissipation component 3, an inner thermal conductive ring 35 is installed on the inner side of the thermal conductive silicone paste 34, a heat dissipation hole 36 is provided at the front end of the thermal conductive silicone paste 34, an annular oil channel 12 is fixedly installed on the inner side of the inner thermal conductive ring 35, and an oil retaining inner ring 15 is fixedly installed on the inner side of the annular oil channel 12.
[0030] It is worth noting that during the operation of the motor, the rotor at its end will generate a large amount of heat through the rotating shaft, which will be transferred to the rotating shaft and then to the oil retaining ring at its outer end. The inner heat conductive ring 35 inside the oil retaining ring transfers its heat to the thermal conductive silicone paste 34 to cool it down. The thermal conductive silicone paste 34 is a single-component dealcoholized room temperature curing silicone rubber, which has the effect of cooling and bonding components. It can be cured into an elastomer with higher hardness in a short time. After curing, it fits tightly with the contact surface to reduce thermal resistance, which is beneficial to the heat conduction between the heat source and its surrounding structure. It has the advantages of high thermal conductivity, good insulation performance and ease of use. It has good adhesion to metals including copper, aluminum, stainless steel, etc. The curing form is dealcoholized and does not corrode metal and non-metal surfaces. The heat it dissipates is discharged by the heat dissipation holes 36. The surrounding condensation belt 1 31 and the surrounding condensation belt 2 33 cool the heat directed to the outer ring rail 11. At the same time, the outer wall air holes 32 prevent continuous accumulation of heat and prevent the lubricating oil from leaking out due to reduced viscosity due to increased temperature, thereby causing oil leakage.

[0032] During specific use, the inner oil retaining ring 15 and the oil guide ring 17 prevent the inner lubricating oil from flowing out, and the inner oil return groove 13 increases the overall working area of the oil return groove, thereby increasing the return speed of the lubricating oil.
[0033] When the heat dissipation structure of an oil retaining ring of the utility model is in use, firstly, a connecting assembly 2 is installed inside the main body 1 of the oil retaining ring with high efficiency in heat dissipation. When the oil retaining ring is transported, its connection is easy to disassemble, which can save a lot of space and is convenient to carry. When the oil retaining ring needs to be used, the end of the upper assembly plate 22 is docked to the opening of the upper fitting groove 24, and the side connecting guide groove 23 and connecting guide groove 1 21 of the assembly plate 22 are matched and locked with the locking plate 1 25 inside the fitting groove 24. The convex plates on both sides of the assembly plate 22 are matched with the grooves on both sides of the fitting groove 24 for guidance, and the limit seat 27 limits the assembly plate 22 after docking to avoid the deviation of its docking position, so as to facilitate the storage and transportation of the oil retaining ring. During the working process of the motor, the rotor at the end of the motor will generate a lot of heat through the rotating shaft, which is transferred to the rotating shaft and then to the oil retaining ring at its outer end. The inner heat-conducting ring 35 inside the oil retaining ring transfers its heat to the thermally conductive silicone patch 34 to cool it down. The thermally conductive silicone patch 34 is a single-component dealcoholized room-temperature curing silicone rubber, which has the effect of cooling and bonding components and can be cured into an elastomer with higher hardness in a short time. After curing, it fits tightly with the contact surface to reduce thermal resistance, which is beneficial to the heat conduction between the heat source and its surrounding structure. It has the advantages of high thermal conductivity, good insulation performance and ease of use. It has good adhesion to metals including copper, aluminum, stainless steel, etc. The curing form is dealcoholized and does not corrode metal and non-metal surfaces. The heat it dissipates is discharged through the heat dissipation holes 36. The surrounding condensation belt 1 31 and the surrounding condensation belt 2 33 cool the heat directed to the outer ring rail 11. At the same time, the outer wall air holes 32 prevent continuous accumulation of heat and prevent the lubricating oil from leaking out due to reduced viscosity due to increased temperature, thereby causing oil leakage.
