Abstract
A belt and sheave assembly for an elevator system includes a sheave having a plurality of tracking grooves laterally spaced across a sheave width, and a debris channel located in a tracking groove of the plurality of tracking grooves defining a radially inwardmost extent of the tracking groove. The assembly further includes a belt having a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, a jacket at least partially enclosing the tension members, the jacket defining a side of the belt configured to interface with the sheave, and a plurality of tracking features extending from the side of the belt. The tracking features are laterally spaced across the belt width. Each tracking feature is configured to be received in a tracking groove, and each tension member is laterally offset from each of the tracking features.
