Description

Technical Field

[0001] The present application is a novel high-strength, wear-resistant, and noise-reducing sliding pad slide plate, which relates to the technical field of yaw sliding pads for wind turbine generator sets, and in particular to a high-strength, wear-resistant, and noise-reducing sliding pad slide plate for wind turbine generator sets. Background Art

[0002] In recent years, wind energy, as a clean, renewable energy source, has received increasing attention worldwide. The wind power industry has rapidly grown, and China's new energy strategy has begun to prioritize the vigorous development of wind power. The yaw system is an essential component of horizontal-axis wind turbines and plays a vital role in their utilization of wind energy. Wind turbine yaw systems are generally divided into active and passive yaw systems. Passive yaw relies on wind power through related mechanisms to steer the turbine's rotors toward the wind, while active yaw uses electrical or hydraulic forces to achieve this yaw. Yaw brake pads are a critical consumable component that ensures the proper operation of wind turbines. They must not only provide excellent braking performance but also have a long service life, high compressive strength, corrosion resistance, and zero friction noise during braking.

[0003] At present, the existing yaw brake pad slide is composed of two slides of different sizes, and the pad slide is equipped with circular pads of different diameters. Due to the insufficient contact area of the circular pads and the excessively high bearing pressure, this type of yaw brake pad has defects such as fragmentation, insufficient braking force, and rapid wear, which leads to frequent replacement of friction plates, affecting the normal use of wind turbines and high equipment maintenance costs. Summary of the Invention

[0004] The problem to be solved by the present application is that the yaw brake pad has the disadvantages of being easily broken, having insufficient braking force and wearing out quickly.

[0005] In order to achieve the above-mentioned purpose, the present application is implemented through the following technical solutions: a high-strength, wear-resistant and noise-reducing sliding pad skateboard is divided into two structural forms, the long pad skateboard is composed of a long skateboard, a long pad, and a nylon bolt, and a pad slot is processed on the long skateboard, and the pad slot has a certain depth and a large area. After the long pad is fixed to the pad slot of the long skateboard with glue, the long pad is fastened to the threaded hole of the long skateboard with a nylon bolt to ensure that the long pad does not fall out during friction braking; the pad skateboard is composed of a skateboard, a pad, and a nylon bolt, and the working principle is similar. A pad slot is processed on the skateboard, and the pad slot has a certain depth and a large area. After the pad is fixed to the pad slot of the skateboard with glue, the pad is fastened to the threaded hole of the skateboard with a nylon bolt to ensure that the pad does not fall out during friction braking.

[0006] During the yaw braking process, the contact area of the long pad and the pad increases, and the load capacity per unit area is greatly reduced when the fan loading force remains unchanged, thereby ensuring the service life of the pad. When the friction coefficient remains unchanged, the long pad and the pad not only increase the friction contact area, but also use high-strength wear-resistant materials to ensure that the pad does not break, and the braking performance is higher. Oil filling holes and oil filling holes are added to the long pad slide and the pad slide. By adding lubricating oil, it is ensured that the long pad and the pad do not produce abnormal sounds and noises during the braking process. In summary, this sliding pad slide scheme has a simple structure and has higher reliability, safety and ease of use, thereby generating huge economic benefits.

[0007] Beneficial effects

[0008] The core technology of this application's novel high-strength, wear-resistant, and noise-reducing sliding pad slide is an enlarged sliding pad slide made of high-strength, wear-resistant material. The specific advantages are: 1. Using an extended and thickened wear-resistant material as the friction pad increases the surface area and the friction contact area, compensating for the disadvantages of circular pads that are easily broken and have insufficient braking force; 2. The long pad and pad are glued to the pad slot and fixed with nylon bolts. The pad slot has a certain depth to ensure that the pad does not fall out during friction braking; 3. An oil filling hole is added to the long pad slide and the pad slide, and by adding lubricating oil, the long pad and pad are guaranteed not to produce abnormal sounds or noise during braking.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below with reference to the accompanying drawings and the best embodiments.

[0020] like Figures 1-8 As shown, the high-strength wear-resistant and noise-reducing sliding pad slide provided by the present application is divided into two structural forms. The long pad slide consists of a long slide 1-1, a long pad 1-2, and a nylon bolt 1-3. A pad slot is machined on the long slide 1-1. The prior art uses a circular pad slot for accommodating a circular pad. The depth of the circular pad slot is 3mm and the total area is 66500mm 2 Compared with the circular gasket slots, the gasket slots in this application have a depth greater than 3 mm and an area greater than 114000 mm. 2 The deepening and enlarging of the pad slot can ensure that the friction area of the friction material is increased while the friction coefficient remains unchanged, reduce the pressure load per unit area of the friction plate, reduce the possibility of fragmentation, and achieve higher braking performance. The deepening of the long pad slot ensures that the pad does not fall out during braking. After the long pad 1-2 is fixed to the pad slot of the long slide 1-1 with glue, the long pad 1-2 is fastened to the threaded hole of the long slide 1-1 with nylon bolts 1-3 to ensure that the long pad 1-2 does not fall out during friction braking. The pad slide consists of a slide 2-1, a pad 2-2, and a nylon bolt 2-3. The working principle is similar. The pad slot is machined on the slide 2-1, and the pad slot has a certain depth and a large area. After the pad 2-2 is fixed to the pad slot of the slide 2-1 with glue, the pad 2-2 is fastened to the threaded hole of the slide 2-1 with nylon bolts 2-3 to ensure that the pad 2-2 does not fall out during friction braking.

[0021] During the yaw braking process, the contact area of the long pad 1-2 and the pad 2-2 increases, and the load capacity per unit area is greatly reduced when the fan loading force remains unchanged, thereby ensuring the service life of the pad. When the friction coefficient remains unchanged, the long pad 1-2 and the pad 2-2 not only increase the friction contact area, but also use high-strength wear-resistant materials to ensure that the pads do not break, and the braking performance is higher. Oil filling holes 1-1-1 and oil filling holes 2-1-1 are added to the long pad slide and the pad slide. By adding lubricating oil, it is ensured that the long pad 1-2 and the pad 2-2 do not produce abnormal sounds and noises during the braking process. In summary, the sliding pad slide scheme has a simple structure and has higher reliability, safety and ease of use, thereby generating huge economic benefits.

[0022] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
