Self-Centring Tool for Bearing Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the automotive sector, various types of bearings and bushes require multiple specialized tools for insertion and removal, leading to inefficiencies and inaccuracies due to the need for manual centring and orientation, especially in spatially constrained areas.
Innovation Solution
A tool featuring a spindle with two ramp-form sleeve bodies that self-centre on the component, allowing for axial guidance and pressure application without relying on the component mount, enabling quick and accurate insertion or removal of components with a modular design that accommodates different sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specialized tools are used for different bearing types, then each bearing type can be handled specifically, but the number of tools required increases and manual centring is needed
Solution Approach 1:
The tool is designed with a standardized interface and modular components that allow it to accommodate multiple types of bearings and bushes through different adapter sleeves, eliminating the need for multiple specialized tools while maintaining compatibility with various component types
2Manufacturing precision
If manual centring and orientation are performed, then positioning can be achieved, but time is lost and positioning accuracy may be insufficient
Solution Approach 1:
The tool incorporates self-centring mechanisms where the bearing or adapter sleeve automatically centres itself on the spindle through geometric constraints and ramp-form surfaces, eliminating the need for manual centring operations while ensuring accurate positioning
3Stability of the object's composition
If the tool is supported on the component mount, then stability is provided, but jamming may occur in spatially constrained areas
Solution Approach 1:
The tool is divided into modular segments including the spindle, adapter sleeves, and pressure discs that can be independently positioned and adjusted, allowing the tool to navigate spatially constrained areas without jamming while maintaining operational stability through proper segmentation and arrangement of components
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
The tool ensures reliable centring and positioning of components, preventing jamming and allowing for a wide range of applications with improved efficiency and reduced manual intervention, enabling the use of the same sleeve bodies for multiple hole diameters.
Implementation Method 1
a first sleeve body with a first ramp-form outer circumferential surface for resting on the component in a clearance-free and centred manner
