  • "O" ring locking mechanism
    Patent number: 5080521
    Abstract: The present invention is a locking mechanism to prevent relative axial movement of concentric machine parts. In this invention, opposing annular grooves in the concentric members create an annular recess across the interface of the concentric members in which a deformable ring sits. By this configuration, the deformable ring engages the annular grooves in the concentric members and mechanically inhibits the concentric members from relative axial movement.
