Abstract: A drillbit seal (60) comprises a rigid carrier (80), an elastomeric body (90), and a reinforcing band (100). The rigid carrier (80) has a seatside leg section (81) at least partially forming a rigid IBseat region (65) for static seating (e.g., metal-to-metal pressfit) in a seal-receiving envelope. The elastomeric body (90) at least partially forms a flexible IBspin region (67) with a lip (71) and a flexible OBspin region (68) with a lip (72). The band (100) forms a rigid bridge (73) between the spinside lips (71, 72) for reinforcement and prevention of pressure-induced deformation.

The stator is interlocked by positioning a cover of the stator within a radial opening of the rotor and interlocking the cover with an enclosure member of the rotor. One embodiment of the seal includes an interlocking member as part of the cover. The interlocking member interlocks with a flange of the rotor.

Abstract: A system for providing a seal between a housing and a shaft is formed of at least two ring members connected to each other by relative diametrical expansion with reduced or eliminated axial resilient deformation. The ring members may be held together by an annular protrusion located within a recess. To eliminate play between the protrusion and the recess, the device may be assembled by heating the recess and inserting the protrusion into the recess while the recess is expanded. The improved system can be accurately assembled, with the ring members located very close to each other. The system has improved oil retention and water exclusion properties.

Abstract: A seal between a housing and a shaft is formed of two ring members interlocked together. The two ring members include a rotor and a stator which are interlocked so as to provide a labyrinth passageway for preventing contaminants from reaching a rotating shaft. The stator includes a main portion, which functions to direct fluid from the rotating shaft back into a housing, and a cover portion which covers the rotor, cooperates with the rotor to provide the labyrinth passageway, and includes all opening for directing the contaminants out of the seal. The stator main portion includes a plurality of annular ridges and grooves and an axial groove. The stator cover portion includes an annular recess, which receives an annular protrusion of the rotor. The stator main portion is located axially adjacent to the rotor, while the cover portion is located radially adjacent to the rotor.

Abstract: A two-piece labyrinth seal adapted to be easily and quickly mounted upon a shaft within a housing to minimize downtime of the equipment. The seal is formed of a rotor and a stator. The rotor and the stator are each formed of two relatively equal portions. The rotor portions and the stator portions each mate at an interface. The interface is generally along an axial plane and crosses the plane at least twice within the rotor and within the stator. The rotor is interlocked with the stator. The rotor and stator portions are mechanically connected.

Abstract: A unitized seal includes a unitizing joint which is remotely spaced from a seal lip. The seal requires only two stampings with one elastomeric element bonded to one of the stampings. The remaining stamping forms a one piece wear sleeve having a first section with a wear surface which is engaged by a seal lip formed on the elastomeric element to provide a seal. A second section of this stamping extends angularly away from the wear surface and includes a terminal end which cooperates with the elastomeric element bearing stamping to form the unitizing joint.
