Positive ring retaining system

In a positive retaining ring assembly for axially securing a work element to a shaft, the combination including:

• a shaft adapted to axially receive a work element thereon, said shaft having an annular work element retaining shoulder means thereon, said shaft provided with an annular recess proximate to said shoulder means, said annular recess having a trapezoidal cross-sectional configuration;
• a segmented ring having a trapezoidal cross-sectional configuration, said ring adapted to matingly engage said annular recess and the side of a work element mounted on the shaft intermediate said recess and said shoulder means, said segmented ring provided with an annular groove in the outer circumferential surface thereof;
• clamping band means provided in operative engagement with the outer circumferential surface of said segmented ring, said clamping band means having a raised bead portion provided on the inner surface thereof, said raised bead portion adapted to matingly engage said annular groove provided in the outer circumferential surface of said segmented ring, said clamping band means adapted to selectively exert an inward radial force upon said segmented ring so as to wedge said ring into said recess whereby said ring exerts a resultant axial retentive force against the side of the work member to lockably retain said work member against said shoulder means.
