Friction Device Cage Casing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disk couplings require complex and costly disk carriers with specific designs, limiting modularity and increasing production costs due to the need for form-fitting connections and separate cage-like structures.
Innovation Solution
A friction device where multiple disks form a cage-like support element with torque transmission elements arranged at an angle, eliminating the need for a separate disk carrier, allowing each disk to contribute to the casing and simplifying production by forming the cage casing itself, and enabling torque transmission without form-fitting connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cage-like disk carrier is used to hold friction disks, then the disks can be securely positioned and torque can be transmitted, but the device complexity increases and production costs rise due to the need for separate cage structures and form-fitting connections
Solution Approach 1:
The invention merges the functions of the disk carrier cage and the friction disks into a single integrated component. The disk carrier is designed with radially extending support arms that directly form the structural framework, eliminating the need for separate cage structures. The friction disks are mounted on these support arms in a straightforward manner without requiring complex form-fitting connections, thereby reducing device complexity while maintaining torque transmission capability.
2Reliability
If a complex cage-like disk carrier with form-fitting connections is used, then torque transmission is reliable, but the ease of manufacture decreases and production costs increase
Solution Approach 1:
The disk carrier is segmented into multiple identical support arms radiating from a central hub. Each support arm is a simple, standardized component that can be manufactured independently using conventional machining processes. This segmentation allows for easier manufacturing, quality control, and assembly compared to a monolithic complex cage structure with form-fitting connections.
Solution Approach 2:
The support arms of the disk carrier serve multiple functions: they provide structural support, position the friction disks, and transmit torque. This multi-functionality eliminates the need for separate components for each function, simplifying the overall structure and reducing manufacturing complexity and costs.
3Stability of the object's composition
If separate cage-like structures are used to hold disks, then the disks can be positioned, but the modularity of the system is limited
Solution Approach 1:
The disk carrier is divided into modular support arms that can be independently manufactured and assembled. The friction disks are mounted on these support arms in a straightforward sequence without requiring complex interlocking mechanisms. This modular design allows for easy assembly, disassembly, and reconfiguration of the system, enhancing modularity while maintaining stable disk positioning.
