Mounting device

The structure for providing an annular space, fluid retaining area about a roller-shaped body, which body is normally mounted for rotation on a shaft structure, the resultant structure providing a singular structure, the structure including:

• a. a jacket having an inner shape and size to provide an annular space interiorally thereof when positioned about the roller shaped body;
• b. a nut ring positioned respectively on each of the ends of the roller body and secured thereto to prevent axial movement thereof and being provided with a plurality of circumferentially spaced, blind passages therein;
• c. at least certain of said passages being threaded to receive threaded attachment members therein as received from the respective ends of said roller body;
• d. said nut ring being provided with a sealing ring receiving seat about the outer periphery thereof, said surface being directed outwardly towards the inner surface of said jacket;
• e. at least one compressible sealing member arranged on said sealing ring receiving seat to seal between said nut ring and said inner surface of said jacket;
• f. a compression ring arranged for positioning against said nut ring for compression of said sealing member, said compression ring providing a plurality of circumferentially spaced passages therethrough;
• g. certain of said passages being threaded for receiving threaded attachment elements into said compression ring;
• h. certain of said compression ring passages providing accommodation and aperture, passing openings for threaded attachment elements to be threadedly received into said nut ring;
• i. a plurality of threaded attachment elements received through said compression ring passages and into said nut ring for compression of said sealing member and sealing thereof to said nut ring and said jacket;
• j. a tapered surface being provided selectively on the respective ends of one of said roller body and said jacket;
• k. a split ring member having a mating tapered surface thereon to mate with said selected body and jacket tapered surface;
• l. said split ring member having a plurality of circumferentially spaced passages axially therethrough;
• m. certain of said split ring passages being threaded;
• n. certain of said split ring passages providing accomodation and attachment element openings for threaded attachment elements to be threadedly received in said nut ring;
• o. said threaded passages of said split ring being arranged in axial alignment with said accomodation openings of said compression ring and said accomodation openings of said split ring being in axial alignment with said threaded passages of said compression ring whereby succeeding the placement of and tightening of said compression ring to said nut ring for sealing compression of said sealing member, said split ring may be axially positioned with respect to said roller body and said jacket to provide an unitary structure.
