发明名称 Mechanical seal with spring drive
摘要 A mechanical seal assembly for creating a sealing relationship between a housing and a shaft which is rotatable relative thereto. The seal assembly includes first and second seal rings having axially adjacent and opposed flat seal faces for creating an annular sealing region therebetween. A driving member is nonrotatably secured to the shaft and positioned in close proximity to the second seal ring, and a plurality of resilient drive connectors cooperate between the drive member and the second seal ring in angularly spaced relation therearound for effecting synchronous driving rotation of the second seal ring in response to rotation of the shaft. The resilient drive connector includes first and second concave walls formed respectively on the drive member and the second seal ring, and a coil spring disposed within and at least partially confined by each of the first and second concave walls so that each of the concave walls engages at least several coils of the coil spring for transmitting rotatable driving force from the drive member through the coil spring to the second seal ring.
