  • Patent number: 4030178
    Abstract: A roller for a continuous track on a crawler tractor or the like comprises two sections welded together to define an interior lubrication cavity which communicates by means of lubrication passages to spaces containing bearings and to an exterior lubrication port. Liquid plastic material capable of in situ foaming to form an open cell plastic mass is injected into the cavity and passages wherein it sets into an open cell plastic mass. Subsequently, lubricating oil or grease is injected under pressure through the lubrication port to fill the open cells of the plastic mass for storage and subsequent supply to the bearings through the lubrication passages. The open cell plastic mass also provides a barrier or filter for particles of contaminants disposed in the cavity as a result of welding and other manufacturing steps and prevents circulating of such particles with the lubricant and damage to the bearings and seals.

  • Patent number: 3955646
    Abstract: A track roller for a continuous track on a crawler tractor or the like comprises two sections welded together to define an interior lubrication cavity which communicates by means of lubrication passages to spaces containing bearings and to an exterior lubrication port. The track roller has a central cavity with a foam material holding a lubricant in its open cells. Axles extend from the track roller and through which a passage extends to communicate with the cavity. The axles are supported by bearings in the caps that are fixedly and non-rotatably mounted on the frame that supports the track roller. The passage in each axle permits lubricant to pass from the cavity to the bearings.
