Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine main gearboxes, specifically a wind turbine main gearbox with a self-heating structure. Background Technology

[0002] Against the backdrop of the global energy structure accelerating its transition to clean energy, wind power, as a mature renewable energy technology, is playing an increasingly important role in electricity supply. The main gearbox of a wind turbine, as the core transmission component of the wind turbine unit, plays a crucial role in converting the mechanical energy of the wind turbine's low-speed rotation into high-speed rotation to meet the generator's operational needs.

[0003] Existing technology discloses a heat dissipation mechanism for a wind turbine gearbox, with publication number CN220566185U. This mechanism includes a heat dissipation box, a heat dissipation cavity, a condensate tank, a condenser, side condenser pipes, an upper condenser pipe, a lower condenser pipe, a front filter, a rear filter, and a cooling fan. The heat dissipation cavity is located at the lower end of the heat dissipation box, the condensate tank is located at the upper end of the heat dissipation box and above the heat dissipation cavity, the condenser is fixed inside the condensate tank, the side condenser pipes are located at one end of the heat dissipation cavity, and the upper and lower condenser pipes are symmetrically arranged at the upper and lower ends of the heat dissipation cavity. This utility model belongs to the field of wind power generation technology, specifically providing a heat dissipation mechanism for a wind turbine gearbox that cools the air surrounding the gearbox through condenser pipes, thereby reducing the blowing temperature and enhancing the heat dissipation effect.

[0004] The aforementioned wind turbine main gearbox with a self-cooling structure cools the air around the gearbox through a condenser pipe. At this time, the cooling fan starts, causing the air in the cooling chamber to flow rapidly, thereby reducing the blowing temperature of the cooling fan and enhancing the cooling effect. However, the above structure does not have a lubrication structure for the gears and bearings, which can easily cause jamming and affect normal use after long-term use. The effect is not good and needs to be improved. Utility Model Content

[0025] The centrifugal lubrication assembly 3 includes a connecting plate 301, a plug-in seal 309, a sealing plate 311, and a centrifugal oil slinger ring 302. The connecting plate 301 is fixedly connected to the left side of the housing 1. An inner shaft 303 is slidably connected to the left side of the housing 1. The centrifugal oil slinger ring 302 is fixedly connected to the surface of the inner shaft 303. An external gear 304 is fixedly connected to the surface of the centrifugal oil slinger ring 302. An oil reservoir 305 is fixedly connected to the left side of the external gear 304. An intermediate connecting oil pipe 306 is fixedly connected inside the oil reservoir 305. A hollow oil replenishment box 307 is fixedly connected to the top of the oil reservoir 305. A connecting column 308 is fixedly connected to the top of the hollow oil replenishment box 307. A pull handle 310 is fixedly connected to the top of the plug-in seal 309. An oil outlet box 313 is fixedly connected to the surface of the external gear 304. A magnet 314 is fixedly connected to the top of the oil outlet box 313. A hinge seat 315 is fixedly connected to the left side of the oil outlet box 313. A magnetic strip 312 is fixedly connected to the top of the body 311. The sealing plate body 311 is hinged to the left side of the oil outlet box 313 via a hinge shaft. This arrangement ensures that the sealing plate body 311 can be flipped towards the oil outlet box 313, which facilitates guidance and ensures normal use of the device. The top area of ​​the magnetic strip 312 is equal to the top area of ​​the magnet piece 314. The magnetic strip 312 is magnetically connected to the magnet piece 314. A mating seat is fixedly connected to the top of the connecting column 308. The inner ring of the mating seat has an internal thread groove. The internal thread of the mating seat is connected to a threaded connection section. The mating seat and the internal threaded connection section allow the insertion seal 309 to be installed and removed. The connection strength is sufficient and it is not easy to separate under external force, which would affect normal use. The insertion seal 309 is fixedly connected to the top of the threaded connection section. An oil outlet groove is opened inside the oil outlet box 313. A hinge shaft is connected inside the hinge seat 315. The surface of the hinge shaft is connected to the sealing plate body 311.

[0026] The heat dissipation assembly 2 includes a high-level oil-cooled heat sink 201, an oil inlet pipe 202, an oil outlet pipe 203, and a hollow pipe 204.

The surface is equipped with an oil reservoir 305, which can be replenished with oil using the intermediate connecting oil pipe 306 and other structures. When replenishing oil, the pull handle 310 can be pulled to rotate the plug seal 309, pulling out the plug seal 309 to expose the oil replenishment port. An oil outlet box 313 is provided on the surface of the external gear 304, and the oil outlet box 313 is connected to the oil reservoir 305, so oil can enter the interior of the oil outlet box 313. During use, the external gear 304 can throw out oil when it rotates centrifugally. During use, the sealing plate 311 can be flipped towards the oil outlet box 313 until the magnetic strip 312 is pressed against the top of the magnet 314, which can guide the oil to ensure that it is immersed on the surface of the external gear 304. It can also splash to the right onto the bearing on the right side for lubrication. After long-term use, it is not easy to get stuck and affect normal use.
