Solution Overview

Problem

Large bearing rings tend to distort under load due to lack of effective force distribution, leading to instability and potential failure.

Innovation Solution

A tensioning arrangement comprising a strap with connectors and a tensioner that applies a circumferentially distributed compressive force to the bearing ring, using a strap that is anchored at one end and tightened by a tensioner to reduce its length and increase tension, thereby preventing distortion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If no tensioning arrangement is applied to the bearing ring, then the bearing ring can rotate freely, but the bearing ring distorts under load due to lack of circumferential force distribution

Engineering Contradiction:
Improvebearing ring stabilityVSAvoidcircumferential compressive force
Core Design Contradiction:
Stability of the object's compositionVSForce

Solution Approach 1:

The patent uses a flexible strap wrapped around the bearing ring to apply circumferential compressive force. The strap acts as a flexible element that can be tensioned to generate the required compressive force distribution around the bearing ring, preventing distortion while maintaining rotational freedom.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The strap serves as an intermediary element between the tensioning mechanism and the bearing ring. By tensioning the strap, the desired circumferential compressive force is transmitted to the bearing ring, mediating the force application to achieve stable operation under load.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a strap is wrapped around the bearing ring and tensioned, then circumferential compressive force is applied to prevent distortion, but the device complexity increases due to additional components

Engineering Contradiction:
Improvebearing ring stabilityVSAvoidtensioning arrangement complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The flexible strap provides a relatively simple and elegant solution compared to rigid mechanical restraint systems. The strap can be easily installed and adjusted, and its flexibility allows it to conform to the bearing ring geometry, reducing installation complexity while maintaining effectiveness.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The tensioning arrangement can be designed to be self-adjusting or easily adjustable, allowing operators to tension the strap to the appropriate level without complex calibration procedures. This self-service characteristic reduces operational complexity while maintaining the stability benefit.

Inventive Principle:
Principle #25Self-service

AI summary

A tensioning arrangement for a bearing ring, which introduces a compressive force towards a rotational centre of the bearing ring, to prevent the bearing ring distorting as a shaft supported by the bearing turns. The tensioner arrangement includes a strap and a tensioner. The strap has a connector at each end, and tensioner has an element for connecting to the connectors. The tensioner also has an element for applying tension to the strap. In use, the strap is arranged around the bearing ring and a circumferential length of the strap in contact with the bearing ring is reduced, thereby applying compressive force to the bearing ring.
