ABSTRACT:
An idler wheel assembly includes a resilient tire and a rim for supporting the tire and for attaching the assembly to an axle. The resilient tire includes a centrally disposed rib with guide grooves on either side thereof disposed between the rib and load supporting surfaces. The rim includes an inner cylinder adapted to mount the assembly on an axle and an outer cylinder maintained in spaced relation to the inner cylinder by spacers. Clamping plates are part of the rim and cooperate with rigid spacer sleeves disposed in bores in the resilient tire to prevent compression of the tire wherein resiliency of the tire is lost. The rib is of a slightly larger diameter than the portion of the tire defined by the load supporting surfaces and cooperates with apertures in an endless belt tensioned therearound to self-center the assembly relative to the belt. The guide grooves cooperate with protrusions on the inside of the endless belt to maintain the alignment of the idler wheel assembly relative to the endless belt under conditions of extreme lateral stress.
