A sealing member, which can have a first end portion and a second end portion opposite the first end portion, can comprise: a body defining a first opening at the first end portion of the sealing member and a second opening at the second end portion of the sealing member; a first ring fitted to the body at the first end portion of the sealing member; and a second ring fitted to the body at the second end portion of the sealing member. A first diameter of the first ring can be less than a second diameter of the second ring. The body can have a flange that extends radially outward, away from a central longitudinal axis of the sealing member, at a second end of the body associated with the second end portion of the sealing member.

A rocker support insert for a support rocker comprises a support plate configured to be removably coupled to a top portion of a rocker body; and a support padding fixedly coupled to a top surface of the support plate such that a portion of the top surface of the support plate remains exposed. A top surface of the support padding can define a concave upward-facing contact surface, and the support padding can be thicker than the support plate.

Rocker support insert

A support rocker configured to be pivotally coupled to a rocker attachment interface of a space frame comprises a rocker body having a pivot bore configured to receive therethrough a pivot pin to pivotally couple the rocker body to the rocker attachment interface; and a rocker support insert provided on a top portion of the rocker body. The rocker support insert can be removably coupled to the top portion of the rocker body, and the rocker support insert can define an upward-facing contact surface.

Rocker support assembly

A seal includes an at least partially cylindrical annular body defining a radial direction, an axial direction, and a circumferential direction. The at least partially cylindrical annular body has a radially outer flange, a radially inner ring, and a resilient intermediate portion joining the radially outer flange to the radially inner ring. The radially outer flange defines a seal outer diameter and a flange axial thickness, and a ratio of the seal outer diameter to the flange axial thickness ranges from 14.0 to 15.0.

A joint assembly includes a clamp member and a spacer plate. The clamp member includes a first jaw surface and a second jaw surface that define a gap therebetween. The spacer plate is connected to the clamp member such that the spacer plate is disposed within the gap between the first jaw surface and the second jaw surface. The spacer plate includes a body and a seal member. The body includes a perimeter. The seal member is connected to the body such that it is disposed adjacent the perimeter of the body. The seal member extends over a segment of the perimeter of the body. The seal member is in sealing engagement with the first jaw surface and the second jaw surface.

A spring seal for a joint assembly pivotally joining a lever arm to a machine frame includes an annular body having a W-shaped cross section. The W-shaped cross section includes a first cantilevered arm, a parallel and spaced apart second cantilevered arm, and a spring leg joining the first and second cantilevered arms. The spring seal is disposed between a bearing surface on the lever arm and a lug on the frame. The W-shaped cross section of the spring seal can collapse and relax to accommodate movement between the lever arm and the frame lug. A second spring seal can be disposed between a second bearing surface on the lever arm and a second frame lug opposite the first lug.

Seal for a joint assembly

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.

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 is connected to the proximal ring face of the ring and to the inner circumferential flange surface of the flange such that the ring is relatively movable with respect to the flange.

Seal member for joint of machine and method of assembling same

A self-adjusting seal for sealing a joint. The joint includes a support member, a mis-alignable component, and a changeable gap between the support member and the mis-alignable component. The seal includes a first part having a generally annular configuration formed of a resiliently crushable material and defining a planar outer seal face to statically seal to the support member and a first seal part opening extending therethrough. A second seal part axially adjoins the first part. The second seal part has a generally annular configuration formed of a rigid material and a second seal part opening extending therethrough in axial alignment with the first seal part opening. The first and second seal part openings define a non-rotation feature to prevent rotation of the seal on the support member, the second seal part defining a planer inner seal face configured to dynamically and sealingly interface with the mis-alignable component.

A load ring for a seal assembly includes an inner axial surface, an outer axial surface, a first frustoconical surface, a second frustoconical surface, and a rib. The inner and outer axial surfaces are cylindrical and extend along a longitudinal axis. The outer axial surface is in outward radial relationship to the inner axial surface along a radial plane which is perpendicular to the longitudinal axis. The first and second frustoconical surfaces are annular and extend radially between the inner axial surface and the outer axial surface. The second frustoconical surface is in spaced relationship with respect to the first frustoconical surface along the longitudinal axis. The rib projects radially inwardly from the inner axial surface.
