Base Ring Roller Installation for Faster Shaft-Hub Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual installation of rollers in shaft-hub connections is time-intensive, especially for large quantities, and requires removal of temporary fastening methods like cable ties, which complicates the process.
Innovation Solution
An installation device with a base ring featuring radially inward recesses and retaining bridges that securely hold rollers during installation, allowing for automated placement and ensuring retention without manual fixing, while also serving as a spacer for insulation and lubricant flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual retention methods like cable ties are used to secure rollers on the shaft, then the rollers can be retained during installation, but the installation process becomes time-intensive and complex
Solution Approach 1:
The base ring serves as an intermediary device that temporarily holds multiple rollers in a predetermined pattern before installation. The base ring with its radially inwardly open recesses and retaining bridges provides a mediator structure that secures rollers during handling and installation, eliminating the need for time-consuming manual fastening with cable ties while ensuring reliable roller retention
Solution Approach 2:
The rollers are pre-positioned and secured in the base ring before the actual installation onto the shaft. The base ring is equipped with the corresponding number of rollers in advance, and this pre-assembled unit is then pushed onto the shaft as a single operation, performing the retention function beforehand to streamline the installation process
2Reliability
If manual securing of rollers is performed, then the rollers can be retained on the shaft, but the installation process becomes complex requiring removal of temporary fastening methods
Solution Approach 1:
The base ring acts as an intermediary carrying structure that simplifies the installation process. Instead of manually securing each roller individually with complex temporary fastening methods, the base ring provides a unified retention mechanism with radially inwardly open recesses and retaining bridges that holds multiple rollers in a predetermined pattern, reducing overall process complexity
Solution Approach 2:
The base ring combines multiple retention functions into a single integrated structure. The radially inwardly open recesses and retaining bridges work together as a unified system to secure multiple rollers simultaneously, merging what would otherwise be separate retention operations into one simple installation step that requires no removal of temporary fastening methods

AI summary
An installation device for installing rollers in a shaft-hub connection includes a base ring having radially inwardly opening recesses configured to receive axial end portions of the rollers. The recesses extend axially and are distributed circumferentially, and the base ring including the received rollers is configured to be pushed onto a shaft. Also an installation method of installing the installation unit and rollers between a shaft and a hub.
