ABSTRACT:
In a drive sprocket of a passenger conveyer, such as an escalator, having a step chain, the sprocket is provided with an overlay attached to the side of the drive sprocket. The overlay cushions the chain as it engages the drive sprocket teeth to thereby minimize the noise generated by the engagement of the drive sprocket and the step chain. In a particular embodiment, a drive sprocket further includes a plate that provides lateral support of the overlay during engagement with the step chain.
