Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baling presses with reduction gear assemblies are large, heavy, and inefficient due to the need to transmit high power levels, leading to increased weight and CO2 emissions, as well as higher costs.
Innovation Solution
A reduction gear assembly using parallel kinematic chains and torque distribution means to distribute power across multiple paths, reducing the size and weight of the gear system by utilizing a variable face width driven gear and incorporating a differential device for efficient torque distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a conventional reduction gear assembly is used to transmit high power levels, then the required force for bale forming is achieved, but the dimensions and weight of the assembly become considerably large and heavy
Solution Approach 1:
The power transmission path is segmented into multiple parallel kinematic chains instead of a single chain. Each chain carries a portion of the total power, allowing the use of smaller, lighter gears in each individual chain while collectively transmitting the full high power level required for bale forming.
Solution Approach 2:
The invention transitions from a single-dimensional power transmission path to a multi-dimensional parallel architecture with multiple kinematic chains. This dimensional expansion allows power to be distributed across multiple pathways, reducing the load on each individual gear and enabling weight reduction in each component.
2Power
If a conventional reduction gear assembly with large gears is used, then high power transmission is achieved, but the overall weight of the machine increases
Solution Approach 1:
The power transmission system is divided into multiple parallel kinematic chains, each handling a fraction of the total power. This segmentation allows each gear in the parallel chains to be smaller and lighter, while the collective system maintains the full power transmission capability required for high-force bale forming operations.
Solution Approach 2:
Multiple parallel kinematic chains are merged to work together in transmitting power to the driven shaft. The combined effect of all chains achieves the required high power transmission, while each individual chain uses lighter components, resulting in reduced overall machine weight.
3Force
If a heavy reduction assembly is used to ensure sufficient power transmission, then the required force is available, but CO2 emissions from the towing tractor increase
Solution Approach 1:
By segmenting the power transmission into parallel kinematic chains, the invention reduces the weight of the reduction assembly. This weight reduction decreases the overall mass of the baling press, which in turn reduces the fuel consumption and CO2 emissions of the towing tractor while maintaining sufficient force for bale forming.

AI summary
A reduction gear assembly (1a, 1b), particularly for the transmission of high power levels, comprising at least one driving shaft (2) and at least one driven shaft (4), which are kinematically connected to each other by transmission means (5a, 5b) and are mutually non-coaxial. The transmission means (5a, 5b) comprise at least one first kinematic chain and at least one second kinematic chain, which are parallel to each other and have the same transmission ratio. More specifically, between the driving shaft (2) and the kinematic chains torque distribution means (7a, 7b) are interposed which are adapted to distribute the power that can be transmitted from the driving shaft (2) to the driven shaft (4) partly through the first kinematic chain and partly through the second kinematic chain. Moreover, the transmission means (5a, 5b) comprising a single driven gear (6), which is keyed onto the driven shaft (4) and is kinematically connected to the kinematic chains.
