Ball Joint Cover Plate Pressing for Single-Step Bearing Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ball joint assembly processes require multiple pressing operations to seat the internal bearing and cover plate, leading to inefficiencies and increased manufacturing costs.
Innovation Solution
A ball joint design and manufacturing method that allows for the simultaneous seating of the bearing and cover plate using a single press operation, facilitated by a tool with a center punch and bearing seat, enabling a more efficient assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple pressing operations are used to seat the bearing and cover plate separately, then each component can be seated precisely, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The patent combines the bearing seating operation and cover plate pressing operation into a single integrated pressing operation. The press tool applies force simultaneously to both the bearing outer race and the cover plate, achieving both seating actions in one step rather than requiring separate operations for each component.
Solution Approach 2:
The pressing tool is designed with multi-functional capability to perform both bearing seating and cover plate pressing through a single operation. The tool configuration allows it to interact with multiple components (bearing and cover plate) simultaneously, making one tool serve multiple functions that would traditionally require separate operations.
2Strength
If multiple pressing operations are performed sequentially, then each component receives adequate pressing force, but the manufacturing time and labor costs increase
Solution Approach 1:
The patent merges multiple sequential pressing operations into one simultaneous operation. By configuring the press tool to engage both the bearing and cover plate at the same time, the manufacturing process eliminates the time required to reposition and re-press between operations, thereby increasing productivity while maintaining adequate pressing force through proper tool design.
Solution Approach 2:
The integrated pressing operation enables continuous useful action by eliminating idle time between separate pressing operations. The press remains engaged in productive work throughout the operation, simultaneously deforming and seating both the bearing and cover plate without interruption or repositioning, thereby maximizing manufacturing efficiency.
3Ease of operation
If the cover plate is pressed before the bearing is seated, then the pressing operation can proceed smoothly, but the internal components cannot be conformally aligned
Solution Approach 1:
The patent applies preliminary action by ensuring the bearing is in its final seated position within the housing before the cover plate pressing begins. The tool configuration and operation sequence are designed so that the bearing seating is accomplished concurrently with or prior to cover plate deformation, guaranteeing that the cover plate is pressed onto properly aligned internal components rather than misaligned ones.

Function Achieved in This Case
This approach streamlines manufacturing, reduces labor costs, and improves the consistency and radial control of internal components, enabling faster production with potential automation and lower production costs.
Implementation Method 1
a pressed portion located between the nested portion and the domed portion having a pressed portion thickness. The pressed portion thickness is less than the domed portion thickness

AI summary
A ball joint includes a cover plate with a nested portion along an outer perimeter having a nested portion thickness, a domed portion located radially inward of the outer perimeter having a domed portion thickness, and a pressed portion located between the nested portion and the domed portion having a pressed portion thickness. The pressed portion thickness is less than the domed portion thickness, which during manufacture, is formed when the cover plate and bearing are simultaneously pressed into their final form and position. A tool can be used to press the cover plate and bearing in a single operation. The tool can have interchangeable components, allowing for the manufacture of differently sized ball joints.
