Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing roller or slide bearings require complex pairing of bearing components, leading to high bearing clearance and running noise due to dimensional and tolerance mismatches, necessitating inefficient sorting and storage processes.
Innovation Solution
A method utilizing synchronized production lines with grinding and honing machines, measuring units, and conveyor systems to produce bearing components that fit precisely, eliminating the need for component pairing by ensuring closed-loop control and direct dimensional matching, thereby reducing mechanical interventions and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If bearing components are produced on separate production lines without synchronization, then production flexibility is maintained, but dimensional mismatches occur leading to high bearing clearance and running noise
Solution Approach 1:
The patent implements closed-loop control where measurement results from the first production line are fed back to control the grinding and honing processes on the second production line. This ensures that bearing components from different production lines achieve precise dimensional matching, eliminating the need for complex post-production sorting and pairing operations.
Solution Approach 2:
The patent performs measurement and dimensional determination on bearing components during the production process itself, before the components are completed. This preliminary action allows the second production line to adjust its processing parameters in advance to ensure dimensional compatibility, rather than dealing with mismatches after production.
2Manufacturing precision
If complex pairing and sorting processes are used to match bearing components, then dimensional precision is improved, but production time and assembly complexity increase
Solution Approach 1:
By implementing real-time feedback control where measurement data from the first production line directly influences the processing parameters of the second production line, the system achieves precise dimensional matching without requiring post-production sorting and pairing operations, thereby maintaining high productivity.
Solution Approach 2:
The system performs dimensional measurement and adjustment during the production process itself, before components are finalized. This preliminary action eliminates the need for subsequent sorting, pairing, and intermediate storage operations, significantly reducing production time and assembly complexity.
3Reliability
If synchronized closed-loop control is implemented across production lines, then bearing clearance and running noise are reduced, but control system complexity increases
Solution Approach 1:
The patent establishes closed-loop control connections between production lines where measurement results from the first line feed into the control system of the second line. This feedback mechanism ensures precise dimensional matching and optimal bearing performance while keeping the control system architecture relatively simple and manageable.

AI summary
A method for producing bearing components includes providing a first bearing component, a second bearing component, a first production line, and a second production line. The first production line has a first grinding machine, a first honing machine, a first measuring unit, and a first conveyor unit. The second production line has a second grinding machine, a second honing machine, and a second conveyor unit. The method also includes grinding and honing the first bearing component, measuring a first dimension of the first bearing component, grinding and honing the second bearing component, and combining the first bearing component and the second bearing component to form a roller bearing or a slide bearing. The first production line and the second production line are operated in a synchronized manner such that the second grinding machine or the second honing machine is operated under closed-loop control using the first dimension.
