Oil Collector Assembly Positioning for Transmission Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission devices with oil collectors face challenges in easy assembly and precise positioning due to the radial spacing of fastening elements, which can be dependent on the radial dimensions of the support plate or channel, limiting adaptability and increasing the complexity of the assembly process.
Innovation Solution
The oil collector design includes axial projections on platforms that extend radially beyond the channel's outer contour, serving as positional aids for assembly and allowing for precise alignment, with snap hooks or expanding dowel-like fastening elements that enable a positive snap connection, independent of the support plate's dimensions, facilitating easier assembly and increased connection force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radial spacing of fastening elements is dependent on the radial dimensions of the support plate or channel, then the structural integrity is maintained, but the adaptability to different supporting component designs is reduced and assembly complexity increases
Solution Approach 1:
The oil collector is segmented into functional zones: the support plate with channel for oil collection, platforms extending radially beyond the channel for positioning, and fastening elements for secure attachment. This segmentation allows each zone to independently fulfill its function without being constrained by the dimensions of other zones, enabling adaptability to different supporting component designs while simplifying assembly.
2Manufacturing precision
If projections are added to platforms for positional orientation, then assembly precision is improved, but the device complexity increases
Solution Approach 1:
The positioning projections are merged with the platforms, forming an integrated structure where the platforms extend radially beyond the channel and include axial projections on their outer surfaces. This combination eliminates the need for separate positioning features, achieving precise assembly positioning without significantly increasing device complexity.
3Ease of operation
If the oil collector is designed with platforms extending radially beyond the channel, then ease of assembly is improved through better positioning, but the device complexity increases
Solution Approach 1:
The platforms with axial projections are pre-formed as integral parts of the oil collector structure, extending radially beyond the channel to provide predetermined positioning features. This preliminary preparation of positioning features enables easy and precise assembly without requiring additional assembly steps or complex alignment procedures.

AI summary
A transmission device includes an axis of rotation defining an axial direction, a supporting component, and an oil collector. The supporting component includes connecting holes and oil inlets. The oil collector includes a support plate, a channel connected to the support plate, oil guiding nozzles plugged axially into the oil inlets, fastening elements for holding the oil collector on the supporting component, and platforms disposed on a side of the fastening elements facing away from the supporting component. The channel runs around the axis of rotation and includes an outer contour. The fastening elements are at least partially fixedly engaged with the connecting holes. The platforms project radially from the oil collector radially beyond the outer contour. Each platform includes a planar surface and a projection. The projection projects out of the planar surface and axially beyond the platform.
