Abstract
A gear assembly includes first and second shafts concentric with one another. First and second gears are respectively provided by the first and second shafts and are arranged adjacent to one another. A biasing assembly cooperates with at least one of the first and second shafts to maintain a desired gap between the first and second gears.
Claims19
A gear assembly comprising:
- first and second shafts concentric with one another;
- first and second gears respectively provided by the first and second shafts and arranged adjacent to one another;
- and
- a biasing assembly cooperating with at least one of the first and second shafts to maintain a desired gap between the first and second gears, wherein the biasing assembly includes a loading member and a biasing element, the loading member engaging an end of one of the first and second shafts and the biasing element urging the loading member against the end.
An integrated drive generator comprising:
- a housing enclosing a generator, a hydraulic unit and a differential assembly, the hydraulic unit and differential assembly configured to cooperate with one another and convert a variable speed and provide a fixed speed to the generator;
- and
- wherein the hydraulic unit includes:
- first and second shafts concentric with one another;
- first and second gears respectively provided by the first and second shafts and arranged adjacent to one another;
- and
- a biasing assembly cooperating with at least one of the first and second shafts to maintain a desired gap between the first and second gears.
A method of spacing adjacent gears in an integrated drive generator, the integrated drive generator comprising a housing enclosing a generator, a hydraulic unit and a differential assembly, wherein the hydraulic unit and differential assembly are configured to cooperate with one another and convert a variable speed and provide a fixed speed to the generator, the method comprising the steps of:
- providing concentric shafts having adjacent gears laterally spaced from one another;
- and
- biasing the shafts relative to one another to maintain a desired gap between the first and second gears.
