Abstract
Abstract In a universal joint there is provided a sealing ring for sealing relative to a trunion and a bearing element surrounding a trunion pin having roller elements adjacent thereto. The sealing ring has a substantially U-shaped cross-section and one leg is positioned between shoulders formed in the bearing element and trunion pin. A portion of a web is positioned in the annular shoulder in the bearing element and the other leg has a sealing lip engaging the trunion pin. A further portion of the web extends radially inwardly of the bearing element to engage the roller elements and to restrain the roller elements against axial movement.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
138 words
A device for sealing relative to a trunion of a universal joint and a bearing element surrounding a trunnion pin having roller bearings adjacent thereto, and comprising a sealing ring of substantially U-shaped cross-section having first and second legs interconnected by a web, said sealing ring consisting of a resilient material, there being a first annular shoulder on a bearing element and a second annular shoulder on a trunnion pin, said sealing ring first leg supported between said shoulders to position the sealing ring axially, said second leg having a sealing lip resiliently engaging the trunnion pin such that any excess lubricant can flow from the roller elements to the exterior of the joint, said web positioned within said first shoulder and having a portion engageable with the roller elements to restrain said roller elements against axial movement.
