ABSTRACT:
A lubricant transfer connection for transferring lubricant from a lubricant transfer line which feeds into a lubricant supply bore machined in a bearing support housing. A lubricant transfer bushing is located at the moving interface between the lubricant supply bore machined in the bearing support housing and a lubricant input port in a cam follower lever arm. The lubricant transfer bushing is designed so that it provides a movable, sealed, connection between the lubricant channel in the bearing support housing and the lubricant input port in the cam follower lever arm, in all positions of the cam follower and cam follower lever arm. A lubricant passage through the lubricant transfer bearing is sized and positioned sufficiently to allow it to provide a passageway between the lubricant channel in the bearing support housing and the lubricant input port in the cam follower lever arm in any angular position of the cam follower lever arm, but the overlap of the passages is not excessive, so that the lubricant channel and the lubricant input port are not exposed to the atmosphere to cause leaks. The lubricant input port in the cam follower lever arm leads to passages in the cam follower lever arm and the cam follower, which transfer lubricating lubricant from the lubricant input port to the cam follower without leakage.
