Offset Reverse Idler Support for Transmission Shaft Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing an effective support system for the reverse idler shaft within a transmission housing is challenging due to its short length, requiring adequate support at both ends while maintaining structural integrity and efficiency.
Innovation Solution
A reverse idler support article comprising a disk member, a plateau, and a hollow cylinder, connected to form an interior space with an offset hole that allows for offset support, enhancing the structural integrity and alignment of the reverse idler gear assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the reverse idler shaft is made short to fit within the transmission housing, then the space utilization is improved, but the structural integrity and support capability deteriorate
Solution Approach 1:
The support system is divided into multiple segments: the reverse idler support body with disk member, plateau, and hollow cylinder form one segment, while the reverse idler shaft with gear forms another. This segmentation allows the short shaft to be properly supported at both ends by distributed support structures, resolving the contradiction between short length and structural integrity
Solution Approach 2:
The reverse idler support body acts as an intermediary component between the transmission housing and the reverse idler shaft. It provides the necessary support and alignment for the short shaft, enabling space utilization while maintaining structural integrity through the mediator support structure
2Stability of the object's composition
If the reverse idler shaft is supported at both ends, then the structural stability is improved, but the design complexity increases
Solution Approach 1:
Multiple support functions are merged into a single integrated reverse idler support body. The disk member, plateau, and hollow cylinder are combined to provide both-end support, alignment, and structural stability in one component, reducing design complexity while maintaining stability
Solution Approach 2:
The reverse idler support body performs multiple functions simultaneously: it supports the reverse idler shaft at both ends, provides alignment through the offset hole configuration, and maintains structural integrity. This multi-functionality reduces the number of separate components needed, simplifying the overall design

AI summary
A reverse idler support article includes a reverse idler support body that has a disk member, a plateau and a hollow cylinder. The disk member is connected to and in facial contact with the plateau that projects from a first disk member surface and the hollow cylinder that projects from a second disk member surface to define an interior space. The disk member and the plateau have an offset hole formed therethrough that is in communication with the interior space. The offset hole is oriented offset from a central axis of the reverse idler support body which extends generally centrally through the disk member and the interior space of the hollow cylinder.
