A bearing ring for offshore wind power generation

Abstract

This utility model discloses a bearing ring for offshore wind power generation, relating to the field of wind power generation, comprising a lower bearing body and an upper bearing body. This utility model, through the arrangement of the lower bearing body, upper bearing body, and balls, connects the entire bearing ring via the lower and upper bearing bodies. This multi-layer assembly improves the overall strength of the bearing ring. Simultaneously, a sealing sleeve at the connection point protects the lower and upper bearing bodies, enhancing the sealing performance and strength of the bearing ring. The lower bearing body and anti-corrosion coating, applied to the surfaces of both the lower and upper bearing bodies with hot-dip galvanized coating, provide excellent corrosion and wear resistance, offering long-term effective protection for the bearing ring. Furthermore, the technology is mature and relatively low-cost, making it suitable for corrosion protection of offshore wind power bearing rings.

Description

Technical Field

[0001] This utility model relates to the field of wind power generation, specifically a bearing ring for offshore 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 bearing ring specifically designed for offshore wind power generation is needed.

[0003] Existing bearing rings, when in operation, face challenges due to the harsh marine environment of offshore wind turbines and the large size and weight of their rotors. The bearing rings need high strength to withstand enormous loads, while also possessing high toughness to prevent breakage under impact or alternating loads. Furthermore, the salt spray and moisture in the marine environment easily corrode metal materials, requiring the bearing rings to have excellent corrosion resistance. Special coatings or materials are typically used to improve their corrosion resistance. Therefore, there is an urgent need for a new type of bearing ring specifically designed for offshore wind power generation. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a bearing ring for offshore wind power generation, in order to solve the problem that when using existing UV lamps for curing UV inks, offshore wind turbines are usually in harsh marine environments, and the impellers are large in size and weight. The bearing rings need to have high strength to withstand huge loads, and also need to have high toughness to prevent breakage under impact loads or alternating loads. In addition, the salt spray and moisture in the marine environment can easily corrode metal materials, so the bearing rings must have excellent corrosion resistance. Special coatings or materials are usually used to improve their corrosion resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing ring for offshore wind power generation, comprising a lower bearing body and an upper bearing body, wherein the lower bearing body is coated with an anti-corrosion coating, a connecting rod is installed at the upper end of the lower bearing body, the upper bearing body is installed at the upper end of the connecting rod, ball bearings are installed inside the upper bearing body, and a sealing sleeve is fitted on the outer end of the lower bearing body.

[0006] Preferably, the lower bearing body is uniformly coated with an anti-corrosion coating, and the anti-corrosion coating is a hot-dip galvanized coating.

[0007] Preferably, the lower bearing body is engaged with the upper bearing body via a connecting rod, and the lower bearing body and the upper bearing body are the same size.

[0008] Preferably, the upper bearing body is movably connected to the ball bearing.

[0009] Preferably, the sealing sleeve is tightly fitted to the upper bearing body and the sealing sleeve is tightly fitted to the lower bearing body.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model consists of a lower bearing body, an upper bearing body, and balls. The entire bearing ring is connected by the lower bearing body and the upper bearing body. Through multi-layer assembly, the strength of the entire bearing ring can be improved. At the same time, the lower bearing body and the upper bearing body are shielded at the connection by a sealing sleeve, which can improve the sealing performance and strength of the entire bearing ring.

[0012] 2. This utility model, through the setting of a lower bearing body, an upper bearing body, and an anti-corrosion coating, can provide long-term and effective protection for the bearing rings by means of a hot-dip galvanized coating applied to the surfaces of the lower and upper bearing bodies. Furthermore, the process is mature and the cost is relatively low, making it widely used for corrosion protection of offshore wind turbine bearing rings. Attached Figure Description
