Abstract
A seal assembly configured to be mounted between a rotatable shaft and a housing has a first side and a second side axially spaced from the first side and includes an annular seal support having a first end at the first side of the seal assembly and a second end spaced axially from the first end, at least one seal body configured to form a seal between the shaft and the seal support, the at least one seal body contacting the seal support at a joint, and a resilient annular body mounted between the seal support and the housing. All portions of the resilient annular body are located radially outward of the joint.
Claims20
A seal assembly configured to be mounted between a rotatable shaft and a housing, the seal assembly having a first side and a second side axially spaced from the first side, the seal assembly comprising:
- an annular seal support having a first end at the first side of the seal assembly and a second end spaced axially from the first end;
- at least one seal body configured to form a seal between the shaft and the seal support, the at least one seal body contacting the seal support at a joint;
- and
- a resilient annular body mounted between the seal support and the housing,
- wherein all portions of the resilient annular body are located radially outward of the joint.
A seal assembly configured to be mounted between a shaft and a housing, the seal assembly having a first side and a second side axially spaced from the first side, the seal assembly comprising:
- an annular seal support having a first end at the first side of the seal assembly and a second end spaced axially from the first end;
- at least one seal body configured to form a seal between the shaft and the seal support, the at least one seal body contacting the seal support at a joint;
- and
- a resilient annular body mounted between the seal support and the housing,
- wherein the housing includes a radially inward projecting inner flange located such that the resilient annular body is located between the first side of the seal assembly and the inner flange, the inner flange including at least one opening having a circumferential width, and
- wherein the annular seal support includes at least one projection extending into the at least one opening, the at least one projection having a circumferential width less than the circumferential width of the at least one opening.
A seal assembly configured to be mounted between a shaft and a housing, the seal assembly having a first side and a second side axially spaced from the first side, the seal assembly comprising:
- an annular seal support having a first end at the first side of the seal assembly and a second end spaced axially from the first end;
- at least one seal body configured to form a seal between the shaft and the seal support, the at least one seal body contacting the seal support at a joint;
- and
- shock absorbing means between the annular seal support and the housing for resiliently accommodating radial and axial displacement of the shaft relative to the housing.
