Free-wheel Cage Ring Centrifugal Guide Surface Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing free-wheel cage rings face limitations in maximizing torque transfer within the same installation space and have challenges with the robustness and accuracy of guide surfaces, as well as inefficient production processes.
Innovation Solution
The integration of guide surfaces directly onto the flanged disks eliminates separate pockets, allowing for longer clamping bodies and increased axial length of clamping surfaces, enhancing torque transfer and robustness while simplifying production through machining with the same tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate pockets are used to guide clamping bodies, then the guide surfaces can be provided, but the axial length of clamping surfaces is reduced and production complexity increases
Solution Approach 1:
The guide surfaces are integrated directly into the flanged disks, merging the guidance function with the structural support function. This eliminates the need for separate pockets, thereby maximizing the axial length of clamping surfaces while maintaining guide surface accuracy through direct machining of the flanged disks.
2Reliability
If separate pockets are used for guiding clamping bodies, then guidance can be provided, but production complexity and cost increase
Solution Approach 1:
The guidance function is merged into the flanged disks themselves, which are already necessary structural components. This integration eliminates separate pockets and reduces the number of manufacturing steps, thereby simplifying production while maintaining reliable clamping body guidance through the directly machined guide surfaces on the flanged disks.
3Power
If the axial length of clamping surfaces is increased, then maximum transferable torque increases, but the installation space requirement increases
Solution Approach 1:
The guide surfaces are positioned on the radial faces of the flanged disks rather than requiring additional axial space. This dimensional repositioning allows the clamping bodies to extend their full axial length for torque transfer while the guidance function is provided in the radial direction, thereby maximizing torque capacity without increasing axial installation space requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach increases the maximum transferable torque by 10-20% and improves the accuracy and robustness of the guide surfaces, optimizing the use of clamping body material and reducing production complexity.
Implementation Method 1
the clamping bodies are pressed outward by the centrifugal force acting on them, pivoted in the decoupling sense, and therefore lifted from the free-ring inner ring
Implementation Method 2
the clamping bodies are biased by at least one spring in the coupling sense

AI summary
A free-wheel cage ring, having two annular flanged disks that extend radially and are connected to each other to form an axial intermediate space and have clamping bodies therebetween pivotally arranged in the cage ring and are biased for coupling by a spring, the clamping bodies perform, due to centrifugal force, a pivoting motion for decoupling against the spring force, and at least two guide surfaces are allocated to each clamping body in its axial extent, that engage opposite end peripheral regions of the clamping body, guide them at least in the peripheral direction, and have a break through which the clamping bodies extend to a radially inner clamping surface. The axial length of the clamping body radially inner clamping surface is equal to the total length of the clamping body. The guide surfaces are each formed integrally by recesses on opposite end faces of the flanged disks.
