  • Patent number: 10233962
    Abstract: A threaded retainer in the form of a flange head capscrew is used alone or in combination with a large diameter washer to axially, frictionally engage a head of, or block, a threaded fastener so as to prevent the fastener from backing out and becoming loose. Any tendency of the threaded fastener to turn in a loosening direction is resisted by the threaded retainer, in a first embodiment, wherein frictional engagement between the flange head and/or large diameter washer causes the threaded retainer to tend to tighten, and in a second embodiment wherein the flange head and/or large diameter washer cooperates with a recess arrangement in the fastener to block loosening of the fastener.

    Abstract: A clutch mechanism comprises a planetary gear unit including input transmission, output transmission, and transmission stopping members. Torque entering the input transmission member is outputted downstream of the planetary gear unit by the output transmission member when the transmission stopping member is fixed and is not outputted downstream when the transmission stopping member is unfixed and entering a rotatable state. A rotation prohibiting target has an engaging target and is integral with the transmission stopping member. A rotation prohibiting member has a supporting shaft, a swingable portion at its one end and an engaging portion at its other end to engage the engaging target to enable the transmission stopping member to exert the stopping function. The engaging portion disengages the engaging target to bring the transmission stopping member into an unfixed state. A damper unit absorbs vibration caused in the rotation prohibiting member during a switching operation.

    Abstract: A coupling system includes a dynamoelectric device selectively operable as either a generator or an electric motor, a gas turbine engine, a main differential operably connected between the dynamoelectric device and the gas turbine engine, a rotationally powered accessory engaged with the main differential, an epicyclic start differential operatively connected to the main differential, and a brake mechanism. The brake mechanism is configured for selectively braking the epicyclic start differential when the dynamoelectric device operates as an electric motor to direct torque transmission to the gas turbine engine, and is further configured to cease braking the epicyclic start differential when the dynamoelectric device operates as a generator such that the main differential transmits torque to power the rotationally powered accessory and to the dynamoelectric device.
