Abstract

Proposed is an off centered idler that is more compact than current designs using a pivot arm and spring to provide tension. As shown in Figure 1, the off centered idler 10 comprises a roller 12 mounted to a shaft 14. Shaft 14 mounts to plate 16 and plate 16 attaches to a base 18. Figure 2 illustrates a triangular shaped plate 16 having three slots 20 for rotating the assembly while tensioning a belt (not shown) mounted to roller 12. The periphery of plate 16 contains three cut-outs 22 that cooperate with three teardrops 24 on base 18. A screwdriver blade inserted and twisted at the respective interfaces of cut-outs 22 and teardrops 24 adjust plate 16 about a center line 26 while tensioning the belt. The location of centerline 28 in dimensions X, Y, and Z provide three different start positions for the idler, thereby increasing the idler's working range.
