Problems solved by technology

In cases where contaminants such as mud seep into the bearings, the operating efficiency of the lift cylinders may become poor
For example, if debris accumulates in a bearing, the operation of the bearing may deteriorate, increasing the mechanical load on the bearing, leading to early failure or damage to the bearing

Embodiment Construction

[0034] The present invention generally relates to a joint assembly of a machine. In an embodiment, the invention relates to a sealing member for a joint assembly of a machine. In an embodiment, the invention relates to a seal member for a maintenance-free bearing of a joint assembly of an off-highway machine. In an embodiment, the invention relates to a method of assembling a joint of a machine.

[0035] In an embodiment, a sealing member is provided for a joint between pivot members movable about an axis of rotation of a shaft. The sealing member may include a ring, a flange, and an elastically bendable intermediate portion interposed between the ring and the flange. In an embodiment, both the ring and the flange are more rigid than the middle part.

[0036] In an embodiment, the joint assembly includes a shaft defining an axis of rotation, a pivot member mounted relative to the shaft, the pivot member being pivotable relative to the shaft about the axis of rotation, and a...

Abstract

A seal member (110) for a joint between a pivot member (114) movable about a rotational axis (RA) of a shaft (112) includes a ring (130), a flange (132), and a resiliently flexible intermediate portion (134) interposed therebetween. The ring (130) includes annular distal and proximal ring faces (210, 212) disposed in spaced relationship to each other along a longitudinal axis (LA). The flange (132) includes a pair of flange faces (230, 231) disposed in spaced relationship to each other along the longitudinal axis (LA). The flange (132) includes outer and inner flange surfaces (233, 237) extending along the longitudinal axis (LA) between the pair of flange faces (230, 231) at, respectively, outer and inner flange perimeters (235, 238) thereof. The intermediate portion (134) is connected to the proximal ring face (212) of the ring (130) and to the inner circumferential flange surface (237) of the flange (132) such that the ring (130) is relatively movable with respect to the flange (132).

Description

technical field [0001] The present patent relates generally to a sealing member for a joint assembly of a machine, and more particularly, to a sealing member for a maintenance-free bearing of a joint assembly of an off-highway machine. Background technique [0002] Off-highway machines feature a dump body and work in a variety of environments. Such machines may include one or more jack cylinders configured to selectively pivot the dump body about its rear end from a normal position to a range of dump positions. During dumping, the ends of the jack cylinders attached to the machine frame can pivot about bearings to accommodate different orientations of the dumping body. In the event of infiltration of contaminants such as mud into the bearings, the operating efficiency of the lift cylinders may become poor. For example, if debris accumulates in the bearing, the operation of the bearing may deteriorate, causing increased mechanical loads on the bearing, leading to early fail...
