Contained Bearing Assembly for Axial Misalignment and Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bearing assemblies experience axial misalignment due to repeated deflection of output shafts, leading to decreased performance and potential failure, particularly in systems with significant axial forces and movement.
Innovation Solution
The bearing assembly includes an inner and outer support ring with superhard contact elements that allow relative movement and are supported by thrust bearing elements, containing the inner assembly within the outer assembly to manage axial loading, while preventing rotation and minimizing axial movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the bearing rotor is attached to the output shaft that undergoes repeated deflection, then the bearing assembly can transfer rotational torque, but the bearing rotor becomes axially misaligned with respect to the bearing stator over time
Solution Approach 1:
The bearing assembly incorporates an inner assembly that is configured to move axially relative to the outer assembly, transforming the static bearing structure into a dynamic one that can adapt to shaft deflection. This axial movement capability allows the bearing to maintain proper alignment between the rotor and stator even when the output shaft deflects, thereby preserving reliability while continuing to transfer rotational torque effectively.
2Duration of action of stationary object
If superhard bearing elements are used to increase wear resistance, then bearing durability is improved, but the bearing assembly becomes more complex with multiple attachment methods required
Solution Approach 1:
The bearing assembly integrates multiple functions into unified components. The inner and outer assemblies combine radial and thrust bearing capabilities, while the superhard bearing elements are incorporated directly into the bearing rings through standardized attachment methods. This merging reduces the overall structural complexity despite using durable superhard materials, as the design consolidates multiple bearing functions into a compact integrated structure.
