ROTARY ASSEMBLY A rotary assembly having a stationary body, a rotary element disposed adjacent the body, and a shaft rotatably mounted in the body and extending into a first bore in the rotary element. A second bore in the rotary element intersects the first bore. The shaft has an outer surface comprising a cylindrical main portion interrupted by a flat in register with the second bore. A cylindrical torque transmission member is disposed in the second bore and has a flat circular end face compressively urged into abuttment with the flat on the shaft. The flat has circumferentially spaced side edges and axially spaced end edges and is continuous with the cylindrical main portion of the outer surface at the side edges and spaced inwardly from the cylindrical main portion at the end edges. The diameter of the end face of the torque transmission member extends laterally beyond the side edges but lies between the end edges of the flat. |
