A synchronous belt sprocket includes a generally circular body including a circumferential belt engagement surface, a plurality of teeth extending radially outwardly from the circumferential belt engagement surface, and at least one flange coupled to the body. The at least one flange has a first end adjacent the body, a second end generally opposite the first end and radially outward from the first end, a surface extending between the first and second ends and facing the circumferential belt engagement surface, and a length defined between the first and second ends. At least half the length of the surface of at least one flange facing the circumferential belt engagement surface is obtusely angled relative to the circumferential belt engagement surface. |
