Variable Turbine Adjustment Ring Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing variable turbine geometries in charging devices face issues with wear and complexity due to the interaction of multiple moving parts, leading to reduced service life and increased costs.
Innovation Solution
An adjustment ring with a disk-shaped body and reinforcement means that surrounds coupling regions, reducing surface pressure and integrating functions such as detents and radial mounting, thereby reducing wear and eliminating the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple moving parts are used in variable turbine geometry, then the adjustment functionality is achieved, but wear and complexity increase
Solution Approach 1:
The patent merges the adjustment ring with the vane lever support function by integrating the coupling regions directly into the adjustment ring structure. This eliminates separate support components and reduces the number of moving parts while maintaining the adjustment functionality through the reinforced coupling regions that directly receive the vane levers.
Solution Approach 2:
The adjustment ring is designed to perform multiple functions: it provides structural support through the disk-shaped body, enables adjustment through circumferential movement, and directly supports vane levers through integrated coupling regions. This multi-functionality reduces the need for additional specialized components.
2Reliability
If reinforcement means are added to coupling regions, then wear is reduced, but manufacturing complexity increases
Solution Approach 1:
The reinforcement means is segmented into discrete coupling regions distributed around the adjustment ring. Each coupling region receives reinforcement independently, allowing for localized manufacturing processes that can be applied to specific high-wear areas without complicating the entire component manufacturing.
3Strength
If coupling regions are fully surrounded by disk-shaped body, then robustness is improved, but material usage increases
Solution Approach 1:
The disk-shaped body provides full surrounding of coupling regions only where structurally necessary, with the reinforcement means strategically positioned at coupling regions experiencing high wear. This localized reinforcement approach maintains structural robustness while minimizing unnecessary material usage in low-stress areas.

AI summary
An adjustment ring (200) for a variable turbine geometry (100). The adjustment ring (200) comprises a disk-shaped body (210) and a plurality of coupling regions (220) which are configured in the disk-shape body (210). The coupling regions (220) are spaced apart in the circumferential direction (26), and each coupling region (220) is adapted for at least partially receiving a vane lever (140) for adjusting a guide vane (120) of a variable turbine geometry (100). Each coupling region (220) circumferentially is fully surrounded by the disk-shaped body (210). The disk-shaped body (210) on one or more of the coupling regions (220) has at least one reinforcement means (230) which extends in the axial direction (22) from the disk-shaped body (210) and circumferentially at least partially surrounds the coupling region (220).
