Propulsion system for marine drive |
摘要 |
A propulsion system includes an improved propeller design which increases the durability of the propeller for enhanced rotational vibration damping, while simplifying the structure of the propeller. A rubber coupling is placed within a space that is secured between a propeller hub and an inner member of the propeller. The rubber coupling resiliently couples the propeller hub to the inner member with only the inner member and the propeller hub maintaining the space in which the rubber coupling is placed. The substantially constant size of the space generally isolates the rubber coupling from cyclic tension and compression stresses in the axiel and radial directions as the propeller rotates to improve the durability of the rubber coupling.
