Other embodiments include apparatuses, systems, devices, hardware, methods, and combinations for face couplings. Further embodiments, forms, features, aspects, benefits, and advantages of the present application shall become apparent from the description and figures provided herewith.
Claims21
A gas turbine engine, comprising:
- a first component;
- a second component;
- and
- a face coupling structured to transmit a torque load from said first component to said second component, said face coupling including:
- a plurality of driving teeth extending axially from said first component, each driving tooth having a driving tooth pressure surface and a driving tooth tip edge adjacent to the driving tooth pressure surface;
- and
- a plurality of driven teeth extending axially from said second component, each driven tooth having a driven tooth pressure surface,
- wherein said plurality of driving teeth and said plurality of driven teeth are structured to cooperate to transmit said torque load from said first component to said second component via driving tooth pressure surfaces acting against driven tooth pressure surfaces;
- and
- wherein said plurality of driven teeth include a first root transition structured to prevent said driving tooth tip edge from contacting an adjacent driven tooth.
A face coupling a face structured to transmit a torque load from a first component to a second component, said face coupling comprising:
- a plurality of driving teeth extending axially from said first component, each driving tooth having a driving tooth pressure surface and a driving tooth tip edge adjacent to the driving tooth pressure surface;
- and
- a plurality of driven teeth extending axially from said second component, each driven tooth having a driven tooth pressure surface,
- wherein said plurality of driving teeth and said plurality of driven teeth are structured to cooperate to transmit said torque load from said first component to said second component via the driving tooth pressure surfaces acting against the driven tooth pressure surfaces;
- and
- wherein said plurality of driven teeth include a first root transition structured to prevent said driving tooth tip edge from contacting an adjacent driven tooth.
A face coupling structured to transmit a torque load from a first component to a second component, said face coupling comprising:
- means for transmitting torque from said first component, wherein said means for transmitting is coupled to said first component;
- means for receiving torque from said means for transmitting, wherein said means for receiving is coupled to said second component;
- and
- first means for preventing a tip edge of said means for transmitting from contacting said means for receiving.
