A sealing device for a wheel hub unit is disclosed herein, wherein the sealing device being able, during use, to form a static seal for protecting the wheel hub unit from any environmental pollutant and being provided with a screen, which is engaged with a collar of the wheel hub unit and has a bottom wall, a cylindrical side wall, and a stop edge. The cylindrical side wall is integrated with thebottom wall and is almost perpendicular to the bottom wall, the thickness of the cylindrical side wall is twice the thickness of the bottom wall so as to enable the screen to be rigid, and the stop edge is integrated with the cylindrical side wall on the opposite side of the bottom wall so as to support and abut against the collar in the axial direction in the using process; the closed shaped seatis defined by a shaped groove formed in the collar and the screen, the seat is delimited by the groove and by a shield, the seat is arranged in combination with a gasket, the gasket is defined by a sealing liquid, the sealing liquid is configured to fill and seal the seat and is designed to polymerize when closed between the collar and the shield, and the sealing liquid is preferably an anaerobicsealing liquid.
一种用于轮毂单元的密封装置,其在使用期间能形成用于保护轮毂单元免受任何环境污染物影响的静态密封,并且密封装置设置有遮蔽件,遮蔽件与轮毂单元的轴环接合并具有底壁、圆柱形侧壁和止动边缘,圆柱形侧壁与底壁成一体并且几乎垂直于底壁,圆柱形侧壁的厚度为底壁的厚度的两倍以使遮蔽件较刚性,止动边缘在底壁的相对侧与圆柱形侧壁成一体,以在使用期间在轴向上支承抵靠轴环;封闭的成形的座由形成在轴环中的成形的槽和遮蔽件限定,并且还由槽和遮蔽件界定,座与密封垫组合设置,密封垫由密封液体限定,密封液体被配制为填充并密封座并且被设计为在被封闭在轴环与遮蔽件之间时发生聚合,密封液体优选地为厌氧的密封液体。
