  • Patent number: 9316258
    Abstract: A non-contact sealing system for shaft bearings lubricated with lubricating fluid employs a centrifugal pressurizing seal having a stator ring and a rotor ring with a centrifugal pressure chamber to pressurize the fluid and deliver the fluid to remote portions of a bearing through channels in the bearing housing. The system enables bearings to be lubricated at stations remote from the system as well as bearings supporting shafts oriented in the vertical direction.
    Type: Grant

  • Patent number: 9273730
    Abstract: A non-contact seal for rotatable shafts includes a stator ring and a rotor ring with internal pumping discs. Each of the, the stator ring pumping discs, and the rotor ring is split diametrically into two halves for mounting on a rotatable shaft at an intermediate station without having access to the end of the shaft or without having to remove other components. Various sealing components are employed between the split rings to prevent fluids within the seal from leaking out.

  • Publication number: 20050199462
    Abstract: According to the present invention, a one-way, bi-directional clutch, includes an outer casing, an input shaft, an output shaft and a brake assembly. The input shaft includes a release cam portion and the output shaft includes a locking cam portion. The brake assembly includes a release cam portion that is complementary to the release cam portion of the input shaft, a locking cam portion that is complementary to the locking cam portion of the output shaft, a biasing element and at least one brake pad. The complementary release cam portion of the input shaft and brake assembly are operable to move the brake assembly to a release position when the sufficient torque is applied to the input shaft. The complementary locking cam portions of the output shaft and the brake assembly are operable to move the one or more brake pads to the brake position when the sufficient torque applied to the output shaft.
