DRIVE APPARATUS FOR VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240308326 titled 'DRIVE APPARATUS FOR VEHICLE
Simplified Explanation: The patent application describes a ball bearing system on a rotary shaft without an inner race, reducing ball PCD and dragging loss between balls and inner race.
- The innovation eliminates the need for an inner race in the ball bearing system on the rotary shaft.
- This design reduces ball PCD and dragging loss between balls and the inner race, enhancing durability.
- By integrating the ball bearing with the rotary shaft, dragging loss is reduced, leading to lower motive power loss on the third rotary shaft.
Key Features and Innovation:
- Ball bearing system on a rotary shaft without an inner race.
- Reduction in ball PCD and dragging loss.
- Integration of the ball bearing with the rotary shaft for reduced dragging loss and motive power loss.
Potential Applications: The technology can be applied in various rotary shaft systems where reducing dragging loss and enhancing durability are essential.
Problems Solved: The technology addresses the issues of ball PCD, dragging loss between balls and inner race, and motive power loss on the rotary shaft.
Benefits:
- Improved durability of the ball bearing system.
- Reduced dragging loss and motive power loss.
- Enhanced efficiency in rotary shaft systems.
Commercial Applications: The technology can be utilized in industries such as automotive, manufacturing, and machinery for improved performance and reduced energy consumption.
Prior Art: Readers can explore prior patents related to ball bearing systems on rotary shafts without inner races to understand the evolution of this technology.
Frequently Updated Research: Stay updated on advancements in ball bearing technology, rotary shaft systems, and efficiency improvements in mechanical systems.
Questions about the Technology: 1. How does the absence of an inner race impact the performance of the ball bearing system? 2. What are the specific advantages of reducing ball PCD and dragging loss in this innovation?
Original Abstract Submitted
a ball bearing on one rotary shaft, out of a first rotary shaft and a second rotary shaft, on which a rotation member corresponding to a larger value of a ratio out of values of ratios of a rotation speed of a first rotation member and a rotation speed of a second rotation member relative to a rotation speed of a third rotation member is arranged does not include an inner race. thereby, a ball pcd can be reduced while securing durability of a ball bearing on the one rotary shaft, and dragging loss between balls of the ball bearing and the inner race can be reduced. since the ball bearing integrally configured with the rotary shaft is arranged on the one rotary shaft, reducing dragging loss of the ball bearing relatively largely reduces motive power loss on the third rotary shaft due to dragging loss of the ball bearing.
