PROPELLER SHAFT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18277945 titled 'PROPELLER SHAFT
The water-impermeable cover is designed to reduce the risk of muddy water entering the opening part of the holding ring of a propeller shaft.
- Opening part of the water-impermeable cover extends towards the opening part of the holding ring.
- Fixed at a position to face the opening part of the holding ring of the stub shaft.
- Reduces the risk of muddy water entering the opening part of the holding ring.
- Minimizes the risk of muddy water entering the interior of a center bearing.
Potential Applications: - Marine propulsion systems - Watercraft manufacturing - Marine engineering
Problems Solved: - Prevention of muddy water entering critical components of marine propulsion systems
Benefits: - Improved durability of propeller shaft components - Reduced maintenance costs - Enhanced performance in water environments
Commercial Applications: Title: Water-Impermeable Cover for Marine Propulsion Systems This technology can be utilized in the manufacturing and maintenance of marine propulsion systems, benefiting companies in the marine industry by improving the longevity and performance of their products.
Prior Art: Further research can be conducted in the field of marine engineering and propeller shaft design to explore similar solutions for preventing water ingress in marine propulsion systems.
Frequently Updated Research: Stay updated on advancements in marine engineering and propeller shaft technology to enhance the effectiveness of water-impermeable covers in marine applications.
Questions about Water-Impermeable Covers: 1. How does the design of the water-impermeable cover contribute to the protection of propeller shaft components from water ingress? - The water-impermeable cover is strategically positioned to face the opening part of the holding ring, reducing the risk of muddy water entering critical components.
2. What are the potential long-term benefits of implementing water-impermeable covers in marine propulsion systems? - By preventing water ingress, water-impermeable covers can improve the durability and performance of propeller shaft components, leading to reduced maintenance costs and enhanced operational efficiency.
Original Abstract Submitted
A water-impermeable cover includes an opening part extending toward an opening part of a holding ring of a stub shaft of a propeller shaft, and is disposed to face the opening part of the holding ring. The water-impermeable cover is fixed at a position to face the opening part of the holding ring of the stub shaft, and the opening part of the water-impermeable cover extends to approach the opening part of the holding ring: therefore, even if muddy water etc. scatters obliquely toward the opening part of the holding ring, the risk of muddy water etc. entering the opening part of the holding ring is reduced, and as a result, also the risk of muddy water etc. entering an interior of a center bearing is reduced.
