Patent ID: 8152140

Claim:
A flat belt pulley that securely clamps a flat belt to the pulley, the pulley comprising: a two-piece hub having a center shaft hole with a center axis that defines mutually perpendicular axial and radial directions relative to the pulley, the hub having a cylindrical peripheral surface and first and second circular side surfaces on axially opposite sides of the peripheral surface, and the hub having a two-piece construction including a first piece with a first clamping surface and a second piece with a second clamping surface where the first clamping surface and the second clamping surface oppose each other with the belt there between when securely clamping the belt to the pulley; at least two adjustable fasteners connecting the hub first piece to the hub second piece with the first and second clamping surfaces opposing each other, the adjustable fasteners enabling selective movement of the first and second clamping surfaces toward each other to securely clamp the belt between the first and second clamping surfaces and enabling movement of the first and second clamping surfaces away from each other to release the belt from between the first and second surfaces, the at least two adjustable fasteners being positioned on axially opposite sides of the belt and not through the belt when the belt is securely clamped between the first and second clamping surfaces.
