Abstract

A mechanical transmission system is provided for a barrier operator system for positioning a garage door between open and closed positions. The transmission system includes a rail having a channel to receive a drive sprocket and a return pulley. A drive element is trained around the drive sprocket and return pulley. The system further includes a tensioning system disposed within the channel and includes a return pulley support member and a bracket disposed on an end of the rail for supporting the return pulley support member. In addition, an adjusting screw is interfaced with and extends between the return pulley support member and the bracket, the adjusting screw movable to adjust the position of the return pulley support member relative to the bracket to increase or decrease the tension of the drive element.
