An Analysis of Bearing Lubricant in a Wind Turbine

Abstract

In this project, performance of bearing lubricant for wind turbine were analyzed. The experimental equipment includes fans, anemometers, generators, rectifiers and voltage stabilizers. carbon steel sheet is used as the wind turbine skeleton which was matched with the position of the lock hole of the bearing fixing seat, and is fixed and well-constructed. Material of blades was assembled using aluminum alloy and the fan was driven by a fixed air source in experiment. Power generation of wind turbine as well as vibration data of bearing of wind turbine were investigated. The vibration frequency spectrum of bearing was regularly measured under normal circumstances. Lubrication performance and power generation were investigated by comparison with two different lubrications. The experimental results can be obtained by checking the rotation speed and power generation efficiency of different greases. Though there was no obvious change in rotation speed and power generation, the RMS diagram of vibration spectrum shows a decreased trend. A simple test model using a fan motor was set up for vibration test. The rotation speed was increased in a specific formula of grease that compared with a general grease, which can also be read from the frequency spectrum in vibration test.
