Support Ring Oil Groove Layout for Flexible Gearbox Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission systems face challenges in oil supply due to space constraints and inflexible oil bore positions, leading to complex assembly and potential errors during installation.
Innovation Solution
A transmission design featuring a rotationally symmetrical support ring with a groove that forms an oil line, allowing for flexible installation independent of angular position, and an oil-tight connection with the housing, ensuring reliable oil supply to bearings and other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separately designed pipelines are used to supply lubricating points with oil, then the oil supply can be provided, but they take up space in the narrow transmission housing and compete with other components for a tight space
Solution Approach 1:
The patent merges the oil supply function directly into the support ring structure by forming oil lines within the support ring itself. This integration eliminates the need for separate pipelines, thereby providing reliable oil supply while saving space in the transmission housing.
2Volume of moving object
If the gearbox housing is provided with oil bores, then space is saved, but the position of the mouths of the oil bores is not variable which makes assembly more difficult and represents a potential source of error
Solution Approach 1:
The patent makes the oil supply system dynamic by allowing the support ring to be rotatable relative to the housing. The oil lines are formed within the rotatable support ring, enabling the system to adapt to different angular positions during assembly while maintaining oil supply functionality, thus improving ease of assembly.
3Stability of the object's composition
If the support ring is fixed in the housing with a rigid connection, then the oil line position is stable, but the support ring cannot be installed in any angular position
Solution Approach 1:
The patent introduces rotational movement between the support ring and housing, transforming the static rigid connection into a dynamic rotatable connection. This allows the support ring to be installed in any angular position while maintaining stable oil line positions relative to the rotating support ring itself.
