The invention relates to a sealing device (12) consisting of a lip seal (20) and a spring (21) or another elastic seal which radially and axially compresses the first seal so as to form two sealing lines (25, 25) closed on substantially flat surfaces (14, 17) opposite in the direction of the axis of a protected rolling bearing (8). The device is small and light in weight and can bear centrifugal force in the transverse direction of the rolling bearing. Any further components for securing it may be omitted. And the space requirement is reduced, and the assembly is easy. The device is suitable for the blade root of the variable-pitch propeller.
本发明涉及一种密封装置(12),其由唇形密封件(20)和弹簧(21)或另一弹性密封件组成,所述弹性密封件径向地和轴向地压缩第一密封件,从而形成在沿被保护的滚动轴承(8)轴线的方向相对的基本平坦表面(14、17)上闭合的两条密封线(25、25)。该装置很小并且重量轻,能够承受沿滚动轴承的横向方向的离心力。可以省去用于固定它的任何进一步部件。减少了空间需求,并且易于组装。本发明适用于可变桨距螺旋桨叶片根部的设备。
