密封装置以及缓冲构件
摘要：
本实用新型涉及密封装置以及缓冲构件，其提供一种通过特定的缓冲构件来减少滑动阻力和滑动发热，并且既能持久耐用又能实现节能的密封装置以及缓冲构件。该密封装置安装于设置在具有轴孔的壳体以及插入该轴孔的轴中的一个部件上的环状槽，并将这两个部件之间的环状间隙进行密封；该密封装置具有缓冲构件(11)，所述缓冲构件具有包括向另一部件侧突出的唇前端部(110a)以及从唇前端部(110a)向低压侧延伸的斜面的密封唇，并且在包括斜面的另一部件侧的区域内具有与另一部件滑动接触的滑动部；其中缓冲构件(11)的唇前端部(110a)呈曲面状而形成，并且在斜面设置有环状凹部(113)。
摘要（英）：

The utility model relates to a sealing device and a buffering component, and provides the sealing device and the buffering component which are durable and save energy and can be used for reducing sliding resistance and sliding heat through the specific buffering component. The sealing device is mounted in an annular groove formed in a casing provided with a shaft hole and in a component inserted into a shaft in the shaft hole, and can be used for sealing an annular clearance between the casing and the component. The sealing device has a buffering component (11), wherein the buffering component comprises a front lip end part (110a) protruding towards the other component side and a sealing lip of an inclined plane extending from the front lip end part (110a) to the low pressure side; a sliding part in sliding contact with the other component is arranged in an area of the other component side including the inclined plane; the front lip end part (110a) of the buffering component (11) is shaped like a curved surface, and annular concave parts (113) are arranged on the inclined plane.
