发明名称 BICYCLE SPROCKET AND BICYCLE CRANK ASSEMBLY
摘要 A bicycle sprocket comprises a sprocket body and a chain engagement structure. The chain engagement structure includes a plurality of sprocket teeth. The plurality of sprocket teeth include at least one first tooth and at least one second tooth. The at least one first tooth has a first tooth top extending non-parallel to a sprocket-plane perpendicular to a rotational center axis when viewed from a radial direction of the bicycle sprocket. The at least one first tooth has a first axial chain-engagement width that is larger than an inner link space defined between a pair of inner link plates of a bicycle chain and smaller than an outer link space defined between a pair of outer link plates of the bicycle chain. The at least one second tooth has a second axial chain-engagement width that is smaller than the inner link space.

主权项 1. A bicycle sprocket comprising: a sprocket body having a rotational center axis, a first side and a second side opposite to the first side in an axial direction parallel to the rotational center axis; and a chain engagement structure disposed on an outer periphery of the sprocket body, the chain engagement structure including a plurality of sprocket teeth extending radially outward from the outer periphery of the sprocket body, the plurality of sprocket teeth including at least one first tooth and at least one second tooth, the at least one first tooth having a first tooth top extending non-parallel to a sprocket-plane perpendicular to the rotational center axis when viewed from a radial direction of the bicycle sprocket, the at least one first tooth having a first axial chain-engagement width that is larger than an inner link space defined between a pair of inner link plates of a bicycle chain and smaller than an outer link space defined between a pair of outer link plates of the bicycle chain, the at least one second tooth having a second axial chain-engagement width that is smaller than the inner link space.
