Radial Piston Pump Housing With Integrated Retaining Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radial piston pumps require significant assembly effort and occupy large radial installation spaces due to the need for multiple screws and separate retaining rings, leading to increased costs and operational forces.
Innovation Solution
Integrate a retaining ring into the housing component of the radial piston pump, reducing the number of components and allowing for a compact design with fewer screws, thereby minimizing radial installation space and operational forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate retaining ring is used to secure all covers, then the assembly effort is reduced, but the radial installation space increases
Solution Approach 1:
The retaining ring function is merged with the housing component by integrating a retaining ring groove directly into the housing structure. This eliminates the need for a separate retaining ring component while maintaining the securing function, thereby reducing radial installation space without increasing assembly effort.
Solution Approach 2:
The housing component is designed to serve multiple functions: it provides structural support, defines the radial piston pump geometry, and simultaneously acts as the retaining structure for all covers through its integrated groove. This multi-functionality eliminates the need for additional dedicated retaining components.
2Reliability
If multiple screws are used to secure covers, then the sealing integrity is maintained, but the device complexity increases
Solution Approach 1:
The securing function previously requiring multiple screws is merged into a single integrated retaining ring groove structure that secures all covers simultaneously, reducing component count while maintaining sealing through the groove geometry and associated sealing elements.
Solution Approach 2:
The housing component is segmented to include an integrated retaining ring groove that creates distinct securing zones for each cover while forming a unified structure, allowing individual cover securing without requiring separate fastening components for each.
3Force
If the pressurized diameter is reduced, then the axial force is reduced, but the housing component design becomes more complex
Solution Approach 1:
The retaining ring groove is integrated directly into the housing component structure, allowing the housing to serve as both the pressure-containing element and the retaining structure. This integration enables optimized pressurized diameter without requiring additional complex retaining components.
Solution Approach 2:
The housing component geometry is optimized with specific groove dimensions and positions that allow reduced pressurized diameter while maintaining structural integrity and securing function, balancing force reduction with design complexity.
