摘要： An oil seal for sealing a hollow rotary shaft in a power transmission apparatus, wherein the rotary shaft is formed with an internal flow passage through which oil flows and constituted such that the oil flies out as the rotary shaft rotates, including: a fixed portion that is fixedly attached to a case of the power transmission apparatus; a seal portion that seals the rotary shaft at a position that is axially offset position from the fixed portion and allows the rotary shaft to rotate; and a radiator portion that is formed from a metallic material between the fixed portion and the seal portion, receives the oil that flies out as the rotary shaft rotates, and dissipates heat generated by the seal portion by exchanging heat with the oil.
摘要翻译： 一种用于密封动力传动装置中的空心旋转轴的油封，其中，所述旋转轴形成有内部流动通道，油流过所述内部流动通道，并且构成为使得所述油随着所述旋转轴旋转而飞出，包括： 固定地安装在电力传输装置的壳体上; 密封部，其将所述旋转轴密封在与所述固定部分轴向偏移的位置，并允许所述旋转轴旋转; 以及由所述固定部和所述密封部之间的金属材料形成的散热器部，接收随着所述旋转轴旋转而飞出的油，并且通过与所述油的热交换而散发由所述密封部产生的热量。
