Abstract
Official abstract text for this publication.
To provide a crawler bushing and a crawler link device that can maintain a sealing function stably on a long-term basis and permits easy maintenance for recovery of the sealing function. The bushing includes: crawler bushing body ( 31 ) including large-diameter cylindrical part ( 31 a ) defining an intermediate section along axis (O) and small-diameter cylindrical part ( 31 b ) which defines an end section along axis (O) and is smaller in diameter than large-diameter cylindrical part ( 31 a ); elastic ring ( 32 ) mounted to an outer periphery of small-diameter cylindrical part ( 31 b ); seal ring ( 33 ) which is formed with seal contact end face ( 37 ) at its outer end and coupled to small-diameter cylindrical part ( 31 b ) through elastic ring ( 32 ); reverse tapered surface ( 36 ) and mountain-shaped projection ( 35 ) for preventing outward movement of elastic ring ( 32 ) along axis (O) of small-diameter cylindrical part ( 31 b ); and tongue-shaped projection ( 39 ) and reverse tapered surface ( 40 ) for preventing outward movement of seal ring ( 33 ) along axis (O) of small-diameter cylindrical part ( 31 b ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A crawler bushing assembly having a seal contact end face to be in contact with a seal member disposed axially adjacent to the crawler bushing assembly, wherein the crawler bushing assembly includes: a crawler bushing body having a large-diameter cylindrical part defining an axially intermediate section of the crawler bushing body and a small-diameter cylindrical part having a smaller diameter than that of the large-diameter cylindrical part and defini…
