Seal Member for Joint of Machine

摘要

A seal member for a joint between a pivot member movable about a rotational axis of a shaft includes a ring, a flange, and a resiliently flexible intermediate portion interposed therebetween. The ring includes annular distal and proximal ring faces disposed in spaced relationship to each other along a longitudinal axis. The flange includes a pair of flange faces disposed in spaced relationship to each other along the longitudinal axis. The flange includes outer and inner flange surfaces extending along the longitudinal axis between the pair of flange faces at, respectively, outer and inner flange perimeters thereof. The intermediate portion has a ring end that circumscribes, and is connected to, an outer circumferential ring surface of the ring and a flange end that is connected to the inner flange surface of the flange such that the ring is relatively movable with respect to the flange.

1. A seal member for a joint between a pivot member movable about a rotational axis of a shaft, the seal member comprising:
a ring, the ring including a distal ring face, a proximal ring face, and an outer circumferential ring surface, the distal ring face and the proximal ring face both being annular and being disposed in spaced relationship to each other along a longitudinal axis, the outer circumferential ring surface extending along the longitudinal axis between the distal ring face and the proximal ring face at an outer ring perimeter thereof and circumscribing the distal ring face and the proximal ring face; a flange, the flange closer to the proximal ring face along the longitudinal axis than to the distal ring face, the flange including a pair of flange faces disposed in spaced relationship to each other along the longitudinal axis, the flange including an outer flange surface extending along the longitudinal axis between the pair of flange faces at an outer flange perimeter thereof, the flange including an inner circumferential flange surface disposed radially within the outer flange surface and extending along the longitudinal axis between the pair of flange faces at an inner flange perimeter thereof, the inner circumferential flange surface defining a flange opening; and an intermediate portion interposed between the ring and the flange, the intermediate portion being resiliently flexible, the intermediate portion having a ring end and a flange end, the ring end of the intermediate portion circumscribing, and connected to, the outer circumferential ring surface of the ring, and the flange end of the intermediate portion connected to the inner circumferential flange surface of the flange such that the ring is relatively movable with respect to the flange.
