Solution Overview

Problem

Existing bearing fastening systems for rotating electrical machines require replacement of the fastening ring when switching between different bearing sizes, complicating maintenance and assembly, especially when axial displacement of the shaft must be prevented without disassembling the machine.

Innovation Solution

A semi-circular bearing fastening ring with scaling profiles for accommodating multiple bearing diameters, combined with grounding ring apertures and bracket assemblies, allowing secure fastening and disassembly without removing the bearing, using a single ring for various sizes and enabling conductive grounding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single bearing fastening ring is used for multiple bearing sizes, then the adaptability and ease of maintenance are improved, but the manufacturing precision and structural complexity increase

Engineering Contradiction:

Improvecompatibility with multiple bearing sizesVSAvoidprecision of scaling profiles

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The bearing fastening ring is segmented into multiple functional zones with distinct scaling profiles (first, second, and third scaling profiles) on its inner surface, each designed to accommodate different bearing outer diameters. This segmentation allows a single ring to serve multiple bearing sizes while maintaining precise geometric specifications for each profile type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bearing fastening ring is designed as a universal component that can fasten bearings of different sizes through its multiple scaling profiles. The ring maintains consistent outer diameter and width while varying the inner surface geometry to accommodate different bearing specifications, eliminating the need for multiple specialized rings.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of repair

If the bearing fastening ring is designed with multiple scaling profiles, then the need for component replacement is reduced, but the device complexity increases

Engineering Contradiction:

Improveease of bearing replacementVSAvoidcomplexity of ring structure

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The bearing fastening ring incorporates a removable cover assembly that can be detached to provide access to the bearing. This dynamic feature allows the bearing to be replaced without removing the entire fastening ring from the housing, significantly simplifying maintenance operations while the ring itself maintains a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cover assembly is designed to nest within or attach to the bearing fastening ring structure, creating a compact integrated unit. The grounding ring with conductive bristles also nests within the assembly, allowing multiple functional elements to coexist in a space-efficient configuration.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If grounding system fastening is integrated into the bearing fastening ring, then the device functionality is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improveintegrated grounding capabilityVSAvoidmanufacturing of integrated features

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The grounding function is merged with the bearing fastening function by integrating a grounding ring with conductive bristles into the bearing fastening assembly. The grounding ring is positioned to contact the shaft surface through the bristles, providing electrical grounding while the bearing fastening ring secures the bearing, creating a multi-functional integrated system.

Inventive Principle:

Principle #5Merging (Combining)
