A mounting structure for an electrical device includes a mounting portion and a containing portion. The mounting portion has a mounting surface and an outer surface. The containing portion has an inner surface with protrusions forming an indent, an outer surface, an insertion aperture, and a flow aperture.

Mounting structure

A seal assembly and method of forming a seal assembly provides a seal body having reduced strain during use, thereby increasing service life. The seal body may be formed within certain parameters, such as ranges of height-to-thickness and offset-to-height ratios, which have been found to reduce strain. Additionally or alternatively, the seal body may be modified from an initial configuration to a pre-strained configuration by axially displacing an inner section of the seal with respect to an outer section of the seal, which also reduces strain.

A heat exchanger having a tube bundle disposed within a housing with a resilient end structure disposed in compressed, plug-forming relation at least partially across the heat exchanging cavity. The resilient end structure includes one or more boundary segments extending between an internal wall of the housing and the perimeter of the tube bundle. The boundary segment includes a combination of materials having differing compression characteristics providing enhanced support to the boundary segments.

A work machine tire includes an annular body of elastomeric material that includes a middle radial region. A plurality of unpressurized cavities are defined by the middle radial region and are distributed in a pattern that includes a first radial band of cavities and a second radial band of cavities. Each cavity of the first radial band of cavities is oriented at a positive angle with respect to a radius therethrough, and each cavity of the second radial band of cavities is oriented at a negative angle with respect to a radius therethrough. A material volume of the middle radial region is more than one and a half times greater than the combined void volume of the plurality of cavities.

Endless track laying work machines are provided with a pair of track roller assemblies positioned on opposite sides of the work machine. Each track roller assembly includes an endless rubber belt entrained around a drive wheel, an idler wheel, and a plurality of supporting mid-rollers. An automatic belt alignment system is utilized to align the endless rubber belt during operation of the endless track laying work machine (,). The automatic belt alignment system also provides connection of the idler wheel assembly to a tensioning system and to the forwardly extending nose portion of a track roller frame.

An undercarriage assembly of a track-type work machine includes a drive wheel, an idler wheel, and a plurality of track supporting rollers. The assembly also includes a track belt which contacts the drive wheel, the idler wheel, and each of the plurality of track supporting rollers. The plurality of track supporting rollers includes a first left roller group, a second left roller group, a middle roller group, a first right roller group, and a second right roller group. The plurality of track supporting rollers cooperate with the track belt in order to reduce the number of vibrations and shocks during operation of the track-type work machine.
