摘要
A powered operator assembly for moving an object along a linear axis and particularly for moving doors in a mass transit vehicle utilizing a helical drive member for moving and supporting an attached door panel. The helical drive engages a drive nut that is connected to one of the two door panel hanger assemblies. Each door panel hanger assembly is attached to the door panel and includes at least two rollers which engage the outer surface of a helical drive for motion along the drive axis. One end of such helical drive is connected to an electric prime mover with such prime mover mounted to a stationary bracket mounted to the door opening structure. The second end of the helical drive engages a bearing mounted to a stationary bracket mounted to the door opening structure.
