Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty rolling bearings in high-speed applications face challenges with effective cooling and damping, leading to potential damage from excessive heat and vibrations, which existing solutions often address through complex and costly mechanisms.
Innovation Solution
A rolling bearing arrangement featuring a unitary intermediate element between the outer ring and housing, with a cooling recess for heat dissipation and a damping recess for vibration mitigation, allowing for a combined cooling-damping system that uses a high-viscosity damping liquid for uniform pressure distribution and additional cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanical damping elements are used to counteract vibration-induced damage, then damping performance is improved, but device complexity increases
Solution Approach 1:
The patent combines the damping function and cooling function into a single integrated intermediate element. The intermediate element includes both damping material for vibration attenuation and cooling channels for heat dissipation, eliminating the need for separate damping and cooling systems. This merging approach reduces device complexity while maintaining effective damping performance.
Solution Approach 2:
The intermediate element serves multiple functions simultaneously: it provides damping to counteract vibrations, conducts cooling to dissipate heat generated by friction, and structurally connects the bearing assembly to the housing. This multi-functionality approach allows a single component to address multiple technical requirements, reducing overall system complexity.
2Temperature
If separate cooling and damping systems are implemented, then cooling and damping functions are achieved, but device complexity increases
Solution Approach 1:
The patent merges the cooling system and damping system into a single intermediate element structure. The intermediate element contains integrated cooling channels and damping material, allowing both heat dissipation and vibration attenuation functions to be achieved through one component rather than separate systems, thereby reducing device complexity.
Solution Approach 2:
The intermediate element acts as an intermediary component between the bearing outer ring and the housing. It mediates multiple functions including damping vibrations, conducting cooling, and providing structural support. This intermediary approach allows complex functions to be achieved through a single mediating structure rather than multiple separate systems.

AI summary
A rolling bearing arrangement which has at least one rolling bearing outer ring of a rolling bearing, an intermediate element, and a housing part. The rolling bearing can be inserted into the housing part such that the intermediate element lies between the rolling bearing outer ring and the housing part. A first contact zone is formed between the rolling bearing outer ring and the intermediate element, and a second contact zone is formed between the intermediate element and the housing part. Formed on the first contact zone is a cooling system that has at least one cooling recess through which a cooling agent can flow. Formed on the second contact zone is a damping system that has at least one damping recess via which a damping cavity in the second contact zone can be filled with a damping medium.
