Abstract
A rotary set on a shaft fluid power coupling which may be used on a package wrapping machine is disclosed. The coupling is shown in FIG. 14 of the drawings. The coupling has a first member having a central bore through which a rotary main shaft passes, and is characterized by a face which lies in a plane perpendicular to the shaft which has a cylindrical annular groove therein. A passage within said first member permits fluid to flow to said annular groove. The coupling has a second member which rotates with respect to said first member, and has a face which lies in a plane perpendicular to the main shaft axis of rotation. The second member also has a cylindrical annular extension which extends into said first member cylindrical annular groove. Fluid is passed from the annular space formed between said annular groove and said annular extension to a second member second face which has a fluid passage way connecting means. The second member cylindrical annular extension is engaged with said first member cylindrical annular groove by axially sliding said cylindrical extension into the cylindrical groove.
