Conical Elastomer Bearing Assembly for Secure Premounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conical bearing assemblies face challenges during mounting, as they can fall out of the receiver if not braced immediately, making premounting difficult and requiring significant effort.
Innovation Solution
A bearing assembly with an elastomer body and bearing element featuring an interference fit connection, where the elastomer body has a conical area of effect and a cylindrical outer surface, allowing for premounting without significant effort and minimizing the risk of the bearing falling out, with optional bracing during final mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conical bearings are used, then the bearing can be mounted in a receiving structure, but the bearing may fall out of the receiver during mounting
Solution Approach 1:
The patent applies preliminary action by providing a through-opening in the core of the bearing that allows a connecting element to be inserted before the bearing is fully mounted in the receiving structure. This enabling feature allows the bearing to be retained during mounting operations, preventing it from falling out while maintaining ease of installation.
2Reliability
If two conical bearings are braced against one another, then the bearings are secured in position, but the bracing must take place immediately after placing the bearings in the receiver
Solution Approach 1:
The through-opening in the core enables preliminary action by allowing the connecting element to be prepared and positioned before the bearing is fully installed in the receiving structure. This eliminates the tight time window constraint, as the bracing operation can be performed at any stage during assembly without requiring immediate action after bearing placement.
3Reliability
If a conical receiver is required, then the receiver can accommodate the conical elastic body, but the receiver requires complex machining
Solution Approach 1:
The patent applies inversion by reversing the conical geometry from the receiver to the bearing itself. The bearing includes a conical elastic body that mates with a cylindrical receiver containing a through-opening in its core. This inversion maintains the secure fit benefits of conical geometry while simplifying the receiver to a basic cylindrical form that is much easier to manufacture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy premounting and secure connection of the bearing assembly, reducing the risk of the bearing falling out and allowing for progressive rigidity and high axial loads transmission, while enabling bracing at a later stage during final mounting.
Implementation Method 1
vibrations of the retaining structure are damped by the elastomer bodies so that only damped and ideally no vibrations are transmitted to the unit
Implementation Method 2
the at least one bearing may be connected by interference fit to the inner surface and the elastomer body having a conical area of effect

AI summary
A bearing assembly for mounting a device, such as batteries or battery cases, includes a bearing and a receiving structure having a receiving opening that extends along a longitudinal axis. The bearing may have an elastomer body having a core that comprises a through-opening extending along the longitudinal axis for a connecting element. The bearing may further have a bearing element and an outer surface in the shape of a cylinder jacket extending about the longitudinal axis. In embodiments, the elastomer body bears against a contact surface of the bearing element, the receiving opening has an inner surface in the shape of a cylinder jacket, and the bearing is connected by an interference fit to the inner surface and the elastomer body having a conical area of effect. The invention provides, inter alia, a bearing assembly that can be premounted without a large degree of effort.
