Rotary shaft seal |
摘要 |
An improved rotary shaft seal assembly is disclosed herein. The seal assembly is disclosed in combination with an example of transmission components with which it may be used. The assembly provides a rotary seal for fluid flow between a stationary cylinder and a shaft which rotates within the cylinder. The shaft includes a porting groove and seal grooves on each side of the porting groove. The seal grooves each include a cast iron and a polymeric (such as Teflon(R)) seal which form seals between the shaft and cylinder on both sides of the porting groove.
