Clamping Bolt With Nested Conical Sleeves For Wear Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping bolts fail to securely clamp the intermediate body in interconnection systems, as they are not designed to accommodate wear-induced diameter increases in bores, leading to loose fits and instability over time.
Innovation Solution
A clamping bolt with internally conical sleeves at both ends, allowing for individual clamping of bodies by moving the sleeves along the shaft, with screw connections or hydraulic clamping, to adapt to wear and ensure secure fixation of both the first and second bodies relative to the shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single clamping sleeve is provided on the shaft, then the shaft can be clamped against one body, but it cannot accommodate wear-induced diameter increases in bores of intermediate bodies
Solution Approach 1:
The clamping system is divided into multiple independent clamping sleeves (first and second clamping sleeves) that can be adjusted separately. Each sleeve independently accommodates wear in its respective bore, allowing the shaft to maintain secure fixation with both the first body and the intermediate second body despite diameter increases over time.
Solution Approach 2:
The clamping sleeves are designed to be movable along the shaft in the longitudinal direction, enabling dynamic adjustment to compensate for wear-induced diameter increases. This dynamic capability allows the system to adapt to changing bore dimensions while maintaining reliable clamping.
2Adaptability or versatility
If clamping sleeves are made movable in the longitudinal direction to accommodate wear, then adaptability increases, but the device complexity increases
Solution Approach 1:
The second clamping sleeve is positioned within or alongside the first clamping sleeve, creating a nested arrangement. This nesting reduces the overall space required for multiple clamping mechanisms and minimizes the increase in device complexity while still providing independent wear compensation for both bores.
Solution Approach 2:
Both clamping sleeves share the same basic structure and function (clamping bodies against the shaft), allowing for standardized design and simplification. The universal clamping mechanism design reduces the complexity increase that would result from having multiple different clamping systems.

Function Achieved in This Case
This design enables secure clamping of both bodies, compensating for wear within bores, maintaining stability and facilitating assembly even with larger bore diameters, thereby extending the lifespan of interconnection systems.
Implementation Method 1
the first clamping sleeve, by moving it in the longitudinal direction of the shaft, is structured so as to be able to be clamped against the first body
Implementation Method 2
the second internally conical clamping sleeve which is located, at least partially, within the second bore, and which is structured so as to be able to be clamped against the second body by moving it in the longitudinal direction of the shaft
