Description

Technical Field

[0001] This utility model relates to the field of wind power generation, specifically a high-strength corrosion-resistant bearing ring for wind power generation. Background Technology

[0002] With the continued growth in global demand for clean energy, wind power, as a clean and renewable energy source, is playing an increasingly important role in the energy sector. Wind turbines operate in complex and variable outdoor environments, such as the high-salt-fog environment of coastal areas and the harsh, windy conditions of northern regions. They also need to withstand the enormous dynamic loads from strong winds, vibrations during operation, and drastic temperature changes. Under these conditions, bearing rings, as key components in the transmission system of wind turbines, play a crucial role in supporting the rotating shaft and transmitting loads. Their performance directly affects the stability, reliability, and service life of the entire wind power system. Therefore, a high-strength, corrosion-resistant bearing ring for wind power generation is required.

[0003] Existing bearing rings mostly employ a solid structure design during operation. This solid structure has significant drawbacks: the extensive use of metal materials significantly increases the weight of the rings, resulting in larger dimensions and an overall weight reaching hundreds or even thousands of grams. This not only drastically increases material costs but also poses significant difficulties for equipment installation and transportation. Excessively heavy bearing rings increase the load on the wind turbine's transmission system, reducing equipment operating efficiency and increasing energy consumption. Furthermore, the lack of continuous lubrication leads to accelerated wear of the bearing rings, damaging the anti-corrosion structure and exposing them to air, easily causing rapid corrosion. Therefore, there is an urgent need for a high-strength, corrosion-resistant bearing ring for wind power generation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a high-strength corrosion-resistant bearing ring for wind power generation, in order to solve the problem that existing high-strength corrosion-resistant bearing rings for wind power generation mostly adopt a solid structure design. The solid structure has obvious drawbacks. The extensive use of metal materials significantly increases the weight of the ring itself. Its size is large, and the overall weight can reach hundreds or even thousands of grams. This not only greatly increases material costs, but also brings great difficulties to the installation and transportation of equipment. The excessively heavy bearing ring will increase the load on the transmission system of the wind turbine generator, reduce the operating efficiency of the equipment, increase energy consumption, and at the same time, it cannot be continuously lubricated, leading to accelerated wear of the bearing ring, damage to the anti-corrosion structure, and contact with air, which can easily cause rapid corrosion of the ring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength corrosion-resistant bearing ring for wind power generation, comprising a ring body, wherein a honeycomb support frame is provided on the inner wall of the ring body, and sponge strips are installed on the inner wall of the honeycomb support frame.

[0006] The inner wall of the ring body abuts against a first sealing ring, the outer wall of the first sealing ring abuts against a first fixing cover, the inner wall of the first fixing cover is fixedly connected to a fixing rod, the outer wall of the fixing rod is fixedly connected to a second fixing cover, and one side of the second fixing cover abuts against a second sealing ring.

[0007] Preferably, the honeycomb support frame is engaged with the sponge strips, and the sponge strips are arranged at equal intervals on the inner wall of the honeycomb support frame.

[0008] Preferably, the outer wall of the first sealing ring is in close contact with the outer wall of the first fixing cover, and the outer diameter of the first sealing ring is the same as the outer diameter of the first fixing cover.

[0009] Preferably, the first fixing cover is engaged with the ring body, and the inner wall of the ring body has a slotted design.

[0010] Preferably, the first fixing cover is threadedly connected to the fixing rod, and the fixing rod is symmetrically arranged about the central axis of the first fixing cover.

[0011] Preferably, the outer wall of the second sealing ring is in close contact with the inner wall of the ring body, and the inner wall diameter of the ring body is larger than the outer wall diameter of the second sealing ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model connects the honeycomb support frame by setting the main body of the collar. When the device is used, the honeycomb structure of the honeycomb support frame is composed of hexagonal units, which has good mechanical properties and lightweight effect. It can significantly reduce the weight of the main body of the collar while improving its resistance to deformation and stability, thus increasing the practicality of the device.

[0014] 2. This utility model uses a honeycomb support frame to lock and fix the sponge strip. When using the device, the honeycomb support frame facilitates the injection of lubricating oil into the interior. At the same time, the honeycomb support frame and the sponge strip absorb and store the injected lubricating oil. When the main body of the collar rotates, the opening inside the collar continuously lubricates the connection, prevents contact with air, protects the collar from corrosion, and increases the practicality of the device.
