Agricultural Baler Flywheel Cooling Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural balers face challenges in effectively cooling lubricating oil in their gearboxes, as traditional radiators are expensive, prone to plugging, and require additional power, while standard metal cooling tubes lack sufficient cooling due to inadequate airflow.
Innovation Solution
The design incorporates a cooling circuit with a section positioned adjacent to the flywheel, leveraging the airflow generated by the flywheel's rotation to cool the operating fluid, eliminating the need for additional cooling components like fans, and increasing the cooling effect by extending the cooling section around the flywheel's axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a standard radiator is used to cool the oil, then cooling effectiveness is improved, but cost increases and the radiator is at risk of plugging
Solution Approach 1:
The invention replaces the expensive, plugging-prone standard radiator with a simple, inexpensive cooling section that has no moving parts or complex structures. The cooling section uses basic heat exchange principles with airflow generated by the flywheel, creating a robust, maintenance-free cooling solution that eliminates plugging risks while keeping costs low.
2Temperature
If a standard radiator is used to cool the oil, then cooling effectiveness is improved, but additional power is required to drive the radiator fan
Solution Approach 1:
The cooling system is designed to be self-powered, using the airflow generated by the flywheel's rotation during normal baler operation to drive the cooling process. The flywheel's inherent motion creates the necessary air flow through the cooling section, eliminating the need for separate fans or power sources. The system serves itself by utilizing the mechanical energy already present in the system.
3Device complexity
If a standard metal cooling tube is used, then cooling structure is simple, but cooling effectiveness is insufficient due to inadequate airflow
Solution Approach 1:
The invention merges the cooling function with the existing flywheel structure by positioning the cooling section to utilize airflow generated by the flywheel's rotation. This integration combines two existing components (flywheel and cooling tube) into a synergistic system where the flywheel's motion provides the necessary airflow for effective cooling, achieving both simplicity and effectiveness.

AI summary
The invention provides an agricultural baler (10) a rotatable input shaft, a flywheel (28) operatively connected to the shaft, and an operating component (38), such as a transmission, e.g. a mid-gearbox. The baler (10) also has a cooling circuit (120,220) that permits flow of operating fluid, e.g. oil, there through, where the fluid flows away from and back towards the operating component. The cooling circuit has a cooling section (122,222) that is positioned adjacent to the flywheel (28) so that rotation of the flywheel generates airflow across the cooling section to cool the operating fluid. The invention is advantageous in that it makes use of an airflow that is already generated by the flywheel as it rotates during normal operation of the baler to improve its cooling function.
