Gear Pump Housing With Integrated Bearing for Simpler Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gear pumps for hydraulic units in motor vehicles are costly and require complex installation processes due to separate bearing components.
Innovation Solution
The pump gear is mounted on a bearing structure integrally formed with one of the housing parts, eliminating the need for separate bearing components and allowing for a simplified installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate bearing components are used for the pump gear, then the pump gear can be supported axially, but the number of components increases and production costs rise
Solution Approach 1:
The bearing structure is integrated directly into the housing part, merging the support function with the housing structure. This eliminates separate bearing components while maintaining axial support for the pump gear, thereby reducing device complexity and production costs without compromising reliability
2Reliability
If multiple separate components are used, then the pump gear can be supported axially, but the installation process becomes more complex and time-consuming
Solution Approach 1:
By integrating the bearing structure into the housing part, the number of assembly steps is reduced. The pump gear can be installed directly onto the integrated bearing structure without requiring separate bearing components to be pre-installed, thereby simplifying the installation process and reducing installation time
3Ease of manufacture
If identical drive and pump gears are used, then production costs are reduced, but the gears must be designed to serve multiple functions
Solution Approach 1:
The drive gear and pump gear are designed with identical geometry, allowing the same gear component to serve multiple functions: torque transmission in the drive gear and fluid displacement in the pump gear. This universality reduces production costs by eliminating the need for different gear types while maintaining functional requirements
