Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generator set equipment, in particular to a bushing type elastic support replacement tool. Background Art

[0002] Bushing elastic supports play a vital role in wind turbines. They not only effectively absorb and cushion vibrations, improving system stability and reliability, but also reduce noise, optimize power transmission, adapt to environmental changes, and facilitate maintenance and overhaul. These features together ensure the efficient, safe, and long-term operation of wind turbines.

[0003] The manufacture of bearing pad-type elastic supports typically uses high-strength steel or aluminum alloy as the base material for the bearing, which is processed using CNC machine tools to ensure that the size and shape meet the design requirements. A suitable mold is designed based on the size and shape requirements of the bearing pad-type elastic support. The metal bearing and preformed elastomer are then placed into the mold, ensuring accurate alignment of the components. The assembled parts are then placed in a vulcanizer and heated to a certain temperature to induce cross-linking reaction in the elastomer, forming a strong bond. After vulcanization is complete, the parts are removed and allowed to cool naturally to ensure that their shape is stable.

[0004] Commonly used elastomer materials include rubber and polyurethane, which offer excellent elasticity and durability. However, aging is inevitable in applications exposed to harsh environmental conditions over long periods of time. The main causes include UV radiation, temperature fluctuations, chemical corrosion, fatigue, and oxidative aging. This can lead to a decline in the performance of elastic supports, affecting their shock absorption and cushioning effects, and ultimately, the stability and safety of the entire system. Therefore, elastic supports must be regularly inspected and replaced if any signs of aging are detected.
