Method of assembling hubs, particularly propeller hubs for boat engines

The method of assembling a propeller hub intended for boat engines, which comprises the steps of:

• a. preforming an unvulcanized rubber mass to a tubular shape to provide a bushing having cylindrical inner and outer surfaces each of selected diameter;
• b. forming a hub sleeve to provide a cylindrical exterior surface of a diameter easily accepting said bushing while maintaining face-to-face contact therebetween;
• c. forming a tubular sleeve to provide cylindrical inner and outer surfaces each of selected diameter, the diameter of said inner surface of the tubular sleeve being such as permits manual insertion of said bushing therewithin and in face-to-face contact therewith when said bushing is received on said hub sleeve;
• d. engaging said bushing onto said exterior surface of the hub sleeve in said face-to-face contact therewith;
• e. manually inserting the interengaged bushing and hub sleeve within said tubular sleeve in said face-to-face contact between the bushing and tubular sleeve;
• f. vulcanizing the hub sleeve-bushing-tubular sleeve assembly to impart resilient properties to said bushing while adhering the bushing to said hub sleeve and to said tubular sleeve;
• and thereafter
• g. positioning and securing said assembly within the propeller sleeve of a propeller hub to form the completed propeller hub.
