Abstract
A seal adaptor assembly for use in a stroking universal joint of the type having an outer drive housing member having an exterior wall of non-uniform dimension including spaces between the parts of the housing enclosing the drive channels. The seal adaptor assembly includes an annular body and a plurality of insert having greater rigidity than the material of the annular body and wherein the inserts are located in the annular body at sections thereof that are located within outer housing spaces between the drive channels. The inserts are supported within the annular body at thin wall sections thereof and thereby provide for a more uniform compression of a resilient seal member between the housing and a clamp for holding the resilient seal member in place on the housing.
Claims20
A seal adaptor assembly for use in a stroking universal joint of the type having an outer drive-housing member having a non-circular outer profile wall with outer spaces formed between drive channels defined by an interior wall said seal adaptor assembly comprising;
- an annular body fabricated of a material and having a plurality of cavities configured to occupy the outer spaces in the outer drive-housing member between the drive channels;
- a plurality of inserts each having greater rigidity than the material of said annular body;
- one of said inserts located in each of said cavities to rigidify said annular body for providing a more uniform compression of a resilient seal member by a clamp for holding the resilient seal member in place on the outer drive housing member.
A seal adaptor assembly for use in a stroking universal joint of the type having an inner drive spider assembly with a plurality of circumferentially spaced trunnions and an outer drive housing member having an outer non-circular wall with outer spaces formed between a plurality of elongated drive channels in an interior wall, at said outer drive housing member surrounding said spider assembly, each of said trunnions having a drive roller rotatably mounted thereon and respectively disposed for linear travel in an associated one of said drive channels, said seal adaptor assembly comprising;
- an annular body fabricated of a material and having a plurality of cavities configured to occupy said outer spaces in the outer drive-housing member between the drive channels;
- and
- a plurality of inserts each having greater rigidity than the material of the annular body;
- one of said inserts located in each of said cavities to rigidify said annular body for providing a more uniform compression of a resilient seal member by a clamp for holding the resilient seal member in place on the outer drive housing member.
A method of assembling a seal adaptor assembly on a stroking universal joint having an outer drive-housing member including an outer non-circular wall with outer spaces formed between drive channels defined by an interior wall, said method comprising;
- providing an annular body fabricated of a material and having a plurality of cavities configured to occupy the outer spaces in the drive housing member between the drive channels;
- providing a plurality of inserts each having greater rigidity than the material of the annular body;
- locating each of the inserts in one of the cavities and
- fitting the annular body in place on the outer drive housing.
