ABSTRACT:
A drive assembly comprises an elongated endless drive member, for example a roller drive chain, engaged on a rotary drive member, for example a drive sprocket, and arranged to be driven by the rotary drive member. A guide member, preferably a guide wheel defines a guide surface urged against the tight strand of drive chain on the opposite side to that engaged by the sprocket. The guide surface of the guide member is positioned in contact with the drive chain in the region of initial engagement of the drive chain on the drive sprocket and is arranged to guide the drive chain member on to the drive sprocket. The guide member is positioned for eliminating or inhibiting any radial component of velocity of the drive chain relative to the drive sprocket during engagement of the drive chain by the drive sprocket.
