SHAFT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18499497 titled 'SHAFT
Simplified Explanation: The patent application describes a method of performing surface treatments on different parts of a component to achieve specific hardness requirements.
- The surface treatment is done at a certain depth from the surface of the gear portion to meet the required hardness.
- Another surface treatment is performed at a deeper depth from the surface of the bearing portion to satisfy the hardness range specified for that part.
- By treating the gear and bearing portions at different depths, the hardness distribution is varied between the two sections.
- This ensures that the hardness requirements for each part are met effectively.
Key Features and Innovation:
- Differential surface treatment depths for gear and bearing portions.
- Specific hardness requirements for each part.
- Unique hardness distribution achieved by varying treatment depths.
Potential Applications: The technology can be applied in the manufacturing of various mechanical components where different parts require specific hardness levels.
Problems Solved: This technology addresses the challenge of achieving precise hardness requirements in different sections of a component.
Benefits:
- Enhanced durability and performance of mechanical components.
- Improved wear resistance in critical areas.
- Tailored hardness properties for specific part functions.
Commercial Applications: The technology can be utilized in industries such as automotive, aerospace, and machinery manufacturing for producing high-performance components with optimized hardness properties.
Prior Art: Readers can explore prior research on surface treatment methods for mechanical components to understand the evolution of this technology.
Frequently Updated Research: Stay informed about the latest advancements in surface treatment techniques for mechanical components to enhance the performance and longevity of industrial machinery.
Questions about Surface Treatment Technology: 1. How does the depth of surface treatment impact the hardness of mechanical components? 2. What are the key considerations when determining the optimal hardness levels for gear and bearing portions?
Original Abstract Submitted
At a position of a depth of the first predetermined value from the surface of the gear portion, a surface treatment that satisfies a range of a required hardness defined in advance of the gear portion is performed. A surface treatment is performed at a depth of a second predetermined value from a surface of a bearing portion, the surface treatment satisfying a required hardness in a range prescribed in advance for the bearing portion. Since the second predetermined value is deeper than the first predetermined value, the hardness distribution is made different between the gear portion and the bearing portion. The required hardness in the gear portion and the required hardness in the bearing portion are respectively satisfied.
