20210403107 · 2021-12-30 · ·

Provided is a novel elastic crawler with improved durability. An elastic crawler (1A) includes: a crawler body (2) made of an elastic material; a projection (3) arranged on an inner circumferential surface (21) of the crawler body (2) and made of an elastic material; and a resin member (31) forming a part of the projection (3). The resin member (31) is embedded in the projection (3) such that a lowermost end (31e) of the resin member (31) is arranged at a position higher than a lowermost end (3e) of the projection (3), and a part of the resin member (31) is exposed on a crawler-width-direction side surface (3b1) of the projection (3) and forms a crawler-width-direction side surface (2b1) of the projection (3).

20220227437 · 2022-07-21 · ·

A rim includes a wall, a first annular projection, and a second annular projection. The wall has a first end and a second end. The first end includes a first opening, and the second end includes a second opening that communicates with the first opening to define a bore for a shaft of a track roller. The first annular projection and the second annular projection, which are configured to engage a track, extend radially from the wall. The first annular projection includes a first flange that is configured to constrain movement of the track in a first axial direction. The first flange includes a plurality of notches. The second annular projection includes a second flange that is configured to constrain movement of the track in a second axial direction that is opposite to the first axial direction.
