Circle Drive Motor Orientation for Grading Machine Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grading machine systems for controlling the blade position and torque distribution can interfere with other components and reduce the range of motion or orientation options, limiting their effectiveness in earth sculpting tasks.
Innovation Solution
A grading machine system that includes a circle drive system with a circle drive motor and a gear box, allowing for independent rotation of the circle relative to the drawbar around a circle axis, thereby adjusting the blade cutting angle and torque distribution without interfering with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a planetary gear apparatus is used to increase torque on the output shaft, then torque control is improved, but the system interferes with other components and reduces range of motion
Solution Approach 1:
The patent repositions the circle drive motor from a location that would interfere with machine components to a different spatial arrangement where the motor shaft is substantially parallel to the circle axis. This dimensional repositioning allows the motor to be coupled to the circle through a gear box without interfering with other machine components while maintaining full range of motion capabilities.
Solution Approach 2:
The patent introduces a gear box as an intermediary component between the circle drive motor and the circle. The gear box includes a pinion gear that engages with gear teeth on the circle, allowing torque transmission while accommodating the repositioned motor in a location that does not interfere with other machine components.
2Adaptability or versatility
If the circle drive motor is repositioned with shaft parallel to circle axis, then interference with components is reduced, but gear transmission complexity increases
Solution Approach 1:
The patent divides the power transmission system into separate functional components: the circle drive motor, the gear box with pinion gear, and the circle with gear teeth. This segmentation allows each component to be optimized independently - the motor can be positioned for optimal range of motion while the gear box handles the torque transmission, reducing overall system interference.

AI summary
A grading machine includes a machine body, a grading blade supported by a circle, a drawbar connecting the grading blade and the circle to the machine body, and a circle drive system. The circle drive system includes a circle drive motor and a gear box. The gear box is configured to engage with and rotate the circle relative to the drawbar around a circle axis. The circle drive motor includes an axis of rotation that is perpendicular to the circle axis, and the gear box includes an axis of rotation that is parallel to the circle axis.
