Gyroscopic Gear Device Using Precession for Torque Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gear devices and motor devices fail to efficiently utilize the principle of precession to generate output rotational power effectively, particularly in converting input rotational power from one axis to another with optimal output torque and angular velocity.
Innovation Solution
A gear device or motor device is designed with a body that rotates about three axes, where the rotation of the body about the third axis changes the inclination angle, allowing for the application of torque to increase this angle and limiting the rotation to maintain an inclination between 0 and 90 degrees, enabling a source of motive power to rotate the body at a critical angular velocity, thereby initiating or increasing output angular velocity and torque on the second and third axes.

Engineering Contradiction Analysis
1Power
If the body is rotated at high angular velocity to generate output power through precession, then the output power and torque are improved, but the device complexity increases due to the need for precise control of inclination angle and rotational speed
Solution Approach 1:
The system utilizes the natural precession effect of the rotating body to generate output power without requiring complex external control mechanisms. The inclination angle control is achieved through the inherent dynamics of the rotating body and applied torque, rather than complex active control systems, allowing the device to self-regulate to some extent
Solution Approach 2:
The system changes the inclination angle parameter dynamically to optimize the precession effect and output power generation. By controlling the inclination angle within specific ranges (greater than 0 and less than 90 degrees), the system maximizes the torque and power output while managing the complexity through parameter optimization rather than structural complexity
2Reliability
If the inclination angle is constrained to maintain stability, then the reliability is improved, but the adaptability decreases due to limited range of motion
Solution Approach 1:
The system dynamically adjusts the inclination angle within constrained boundaries to maintain stability while allowing sufficient range for power generation. The inclination angle is kept greater than 0 and less than 90 degrees, providing a dynamic operating range that balances stability and adaptability for different operational conditions
Solution Approach 2:
The system preliminarily sets the inclination angle within optimal ranges before operation to ensure stability and reliable power generation. By pre-configuring the inclination angle constraints, the system ensures reliable operation while maintaining adaptability within the predetermined safe operating envelope
3Ease of operation
If the critical angular velocity is reduced to below 20000 rpm, then the ease of operation is improved, but the productivity decreases due to lower maximum output capability
Solution Approach 1:
The system optimizes the critical angular velocity parameter to a specific value below 20000 rpm, which balances ease of operation with adequate productivity. This parameter optimization allows the device to be easily operated while still generating sufficient output power for practical applications, rather than requiring excessively high rotational speeds

This configuration enhances the efficiency of power transmission by maximizing output power and torque on the output axes, with the device capable of providing high-efficiency rotational power conversion, and the limiting mechanism acts as a switch to trigger output power provision without requiring additional energy.
Implementation Method 1
When a rotating body is acted on by a torque about an axis perpendicular to the axis of rotation, this causes the axis of rotation itself to rotate about a further axis which is perpendicular to both the axis of the applied torque and the axis of rotation. This principle is well known in gyroscopic devices. The effect is named precession.
Implementation Method 2
means for applying a torque to the body about the third axis in the direction of increasing inclination angle when the first axis is at a selected inclination angle with respect to the second axis

AI summary
A gyroscopic device is described for providing rotation about at least one output axis and a method for providing rotation. A body (2) is mounted for a rotation about first (4), second (11), and third (16) axes. The first axis (4) is oriented with respect to the second axis (11) at an inclination angle. The second axis (11) and/or the third axis (16) constitute the at least one output axis of device. The rotation of the body (2) about the third axis (16) gives rise to a change in the inclination angle. A ram (15) applies a torque (21) to the body (2) about the third axis (16) in a sense of increasing inclination angle when the first axis (4) is at a selected inclination angle with respect to the second axis (11) which is greater than 0° and less than 90°. The rotation of the body (2) about the third axis (16) in a sense of decreasing inclination angle is limited such that the inclination angle of the first axis (4) with respect to the second axis (11) remains greater than 0 degrees and less than 90 degrees. The body (2) is rotated about the first axis (4) at an angular velocity greater than a critical angular velocity so that a constant or a decreasing inclination angle is reached.
