Thrust Ring Structure for Axial Clearance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat stop rings provide strong support but cannot compensate for axial clearances, while inclined stop rings can compensate for axial clearances but only bear limited axial forces.
Innovation Solution
A thrust component comprising a stop ring with a stop flat portion and a stop inclined portion, and a position limiting structure with corresponding flat and inclined portions, allowing for adjustable assembly to accommodate axial clearances and bear larger axial forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a flat stop ring is used, then strong support ability for blocked members is achieved, but axial clearances cannot be compensated
Solution Approach 1:
The stop ring is segmented into multiple functional zones: a flat portion (for strong axial support), a first inclined portion (for axial clearance compensation), and a second inclined portion (for additional adjustment). This segmentation allows each zone to perform its specific function independently, resolving the contradiction between providing strong support and compensating for axial clearances.
Solution Approach 2:
Different portions of the stop ring are given different geometric properties: the flat portion provides rigid support for high axial loads, while the inclined portions provide flexibility for axial clearance compensation. This local differentiation of properties allows the single component to satisfy both contradictory requirements simultaneously.
2Ease of operation
If an inclined stop ring is used, then axial clearances can be compensated, but limited axial forces can be borne
Solution Approach 1:
The stop ring is divided into a flat portion and inclined portions, where the flat portion specifically handles axial force bearing while the inclined portions handle axial clearance compensation. This functional segmentation resolves the contradiction by assigning different tasks to different segments.
Solution Approach 2:
The flat portion is designed with high rigidity for axial force bearing, while the inclined portions are designed with appropriate angles for clearance compensation. This local quality differentiation enables the component to simultaneously achieve both axial force bearing capacity and axial clearance compensation.
3Adaptability or versatility
If a complex assembly structure is used to achieve both support and clearance compensation, then both functions are achieved, but device complexity increases
Solution Approach 1:
Multiple functions (axial support, axial clearance compensation, and position limiting) are merged into a single integrated thrust component. The stop ring with its flat and inclined portions, combined with the position limiting structure, achieves all required functions in one assembly, avoiding the need for multiple separate components and reducing overall assembly complexity.
Solution Approach 2:
The thrust component is designed as a universal element that simultaneously provides axial support, compensates for axial clearances, and limits axial position. This multi-functionality is achieved through the integrated design of the flat and inclined portions working together with the position limiting structure, eliminating the need for separate components for each function.
