Abstract

An improved lubrication connector for roller conveyors of the type which includes a pair of idlers positioned end-to-end, each idler being rotatably mounted on a hollow shaft through bearing assemblies. The shafts communicate with associated bearing assemblies which are lubricated by forcing lubricant through the hollow shafts. A flexible tube connects adjacent portions of the hollow idler shafts for transporting lubricant from one shaft to the other. The improvement includes one end of the tube being resiliently held in place relative to one of the hollow shafts so that the interior of the tube will communicate with the interior of said hollow shaft, the other end of the tube being sized and shaped slightly smaller than the interior of the other hollow shaft for allowing the tube to be inserted in the shaft yet large enough to prevent lubricant under pressure from leaking between the tube and shaft. The tube will deflect when the lubricant exceeds a predetermined amount which causes one end to move outwardly in its cooperating hollow shaft. The end is contoured to provide a lubricant leakage passage permitting lubricant to escape from the tube and shaft before the end of the tube reaches the outer end of its cooperating hollow shaft.
