Drive Train Component Assembly Using Guide Elements for Precise Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling drive train components, such as transmission or differential parts, require special features on individual parts and often result in increased costs, complexity, and the risk of housing leaks due to multi-part designs.
Innovation Solution
A method involving a first part with multiple threaded holes and a second part with corresponding through holes, where guide elements are inserted into the threaded holes and extend through the through holes to align the parts, allowing screw elements to be inserted and secured, thereby assembling the component without additional special features on the parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the bearing support part is fixed from outside the housing part using screws, then the connection can be made, but accessibility restrictions require adjustments that increase manufacturing costs and component complexity
Solution Approach 1:
The invention divides the housing into multiple parts (housing part and bearing support part) that can be assembled separately. The bearing support part is first positioned using guide elements, then the housing part is attached, allowing screw fixation from the outside without requiring complex adjustments during assembly
Solution Approach 2:
The guide elements are arranged in the threaded holes before the housing part is fixed to the bearing support part. This preliminary positioning ensures proper alignment is achieved before the actual screw fixation, eliminating the need for complex adjustments during the assembly process
2Manufacturing precision
If adjustments are made to align the bearing support part with the rolling bearing or housing part, then proper screw insertion is enabled, but this increases manufacturing costs
Solution Approach 1:
Guide elements are introduced as intermediary components that facilitate alignment between the bearing support part and the housing part. These guide elements fit into threaded holes and provide precise positioning, enabling accurate alignment without requiring expensive adjustments or specialized tooling
3Ease of operation
If the housing is designed as a multi-part structure to ensure accessibility, then screw fixation is enabled, but the risk of housing leaking increases
Solution Approach 1:
The bearing support part is extracted as a separate component that can be pre-assembled with the rolling bearing and guide elements. This allows the housing to remain relatively simple while still enabling accessibility for screw fixation, as the bearing support part serves as an intermediate interface that doesn't compromise housing integrity
