<p><P>PROBLEM TO BE SOLVED: To provide a seal having excellent durability and wear resistance and preventing a rotor from being brought into contact with a stator during the axial movement. <P>SOLUTION: An assembly for sealing a rotating shaft and a bearing housing which has a stator 10, a rotor 50, and a unitizing element 30. The stator 10 has at least two portions and an annular engagement flange extending in the axial direction and having a groove on the radial side surface thereof. The rotor 50 has at least two portions and an annular engagement flange extending in the axial direction and having a groove on the radial side surface thereof. The annular unitizing element 30 has at least two portions, a stator engaging member that engages the stator groove, a rotor engaging member that engages the rotor groove, and a rear member having a both ends that engage the stator 10. The radial outer surface of the unitizing element 30 has two areas of different diameters, one corresponding to the rotor engaging member and the other corresponding to the rear member. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
