Title:
自己潤滑式転輪アセンブリおよび同アセンブリを使用する機械
Document Type and Number:
Japanese Patent JP2011527973
Kind Code:
A
Abstract:
A track roller assembly for a track-type machine such as an excavator or a tractor includes an outer surface with no fluid ports and an inner surface free from any fluids. The track roller includes self-lubricated bushings, which include a substrate that has lubricating properties, such as a substrate that carries a solid lubricant, which allows the track roller to require no liquid lubrication requiring regular maintenance. The bushing is sealed to prevent debris from entering a clearance between the bushing and the shaft as well as preventing any of the bushing's solid lubricant from escaping.
