Abstract
The present disclosure provides an improved circular force generator having a housing configured to reduce vibrational forces transmitted to an aircraft structure. Additionally, the disclosed configuration provide the necessary safety redundancies required by the aviation industry. The circular force generator includes mounting point around the exterior of the CFG housing and a central mounting point thereby providing redundant mounting points.
Claims20
A circular force generator configured to be mounted to a structure, the circular force generator comprising:
- a housing, the housing having a central opening and a plurality of mounting lugs positioned around an exterior of the housing;
- each mounting lug having a least one mounting lug hole passing through the mounting lug;
- a first fastener passing through each mounting lug hole within the mounting lug, the fastener engaging the structure or carried by the structure thereby securing the circular force generator to the structure;
- an inner shaft positioned within the central opening, the inner shaft having a central passage extending from a first open end to a second closed end;
- a closed end hole passing through the closed end;
- and,
- a second fastener passing through the closed end hole, the second fastener engaging the structure or carried by the structure thereby securing the circular force generator to the structure.
A circular force generator mounting system:
- a housing, the housing having a central opening and a plurality of mounting lugs positioned around an exterior of the housing;
- each mounting lug having a least one mounting lug hole passing through the mounting lug;
- a first fastener passing through each mounting lug hole within the mounting lug, the fastener engaging the structure or carried by the structure thereby securing the circular force generator to the structure;
- an inner shaft positioned within the central opening, the inner shaft having a central passage extending from a first open end to a second closed end;
- a closed end hole passing through the closed end;
- a second fastener passing through the closed end hole, the second fastener having a first end with a bolt head and a second threaded end;
- a circular force generator support structure, the circular force generator support structure comprising:
- a mounting hole configured to receive the second fastener;
- threads positioned within the mounting hole, the threads within the mounting hole engage the second threaded end of the second fastener.
A circular force generator configured to be mounted to a structure, the circular force generator comprising:
- a housing, the housing having a central opening and a plurality of mounting lugs positioned around an exterior of the housing;
- each mounting lug having a least one mounting lug hole passing through the mounting lug;
- a first fastener passing through each mounting lug hole within the mounting lug, the fastener engaging the structure or carried by the structure thereby securing the circular force generator to the structure;
- an inner shaft positioned within the central opening, the inner shaft having a central passage extending from a first open end to a second closed end;
- a first closed end hole passing through the closed end;
- a second closed end hole passing through the closed end;
- a split located in the closed end between the first closed end hole and the second closed end hole;
- a second fastener passing through the closed end hole, the second fastener engaging the structure or carried by the structure thereby securing the circular force generator to the structure;
- and,
- a third fastener passes through the second closed end hole, the third fastener engaging the structure or carried by the structure thereby securing the circular force generator to the structure.
