摘要
随着轿车轮毂轴承向小型轻量化方向发展,对轿车轮毂轴承润滑脂提出了更高的要求,聚脲润滑脂以其优异的抗氧化性能、高温性能、长使用寿命,已广泛用于轿车轮毂轴承润滑。介绍了轿车轮毂轴承用聚脲润滑脂的主要性能,综述国内轿车轮毂轴承用聚脲润滑脂的研究现状,提出应大力发展和推广应用多效、长寿命的通用聚脲润滑脂。
Along with the hub bearings of saloon car developing towards small and lightweight, even higher requirements are asked for the lubricating grease of hub bearings of car. By the outstanding anti-oxidation performance, high temperature performance and long service life, the polyurea grease was widely used for lubrication of hub bearings of saloon car. The main performances of polyurea lubrication grease using in hub bearings of saloon car were introduced, and the present research on polyurea lubricating grease for hub bearings in domestic saloon car was summarized. It is proposed that the general purpose polyurea grease with multi-effect and long service life must be developed with strength and applied in a large extend.
