Solution Overview
Problem
Conventional membrane bellows in compensators are susceptible to damage due to angular misalignment, which is exacerbated by their cylindrical geometry, leading to instability and costly improvements.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional membrane bellows with cylindrical geometry is used, then the structure is simple and成本低, but it is susceptible to damage from angular misalignment and torque
Solution Approach 1:
The compensator is divided into multiple membrane bellows units (first, second, and third membrane bellows) connected in series through bellows couplers. This segmentation allows each bellows to handle specific movement components, with the third bellows specifically designed to compensate for angular misalignment and torque, thereby improving reliability while maintaining manufacturing simplicity
Solution Approach 2:
Bellows couplers are introduced as intermediary components connecting the membrane bellows units. These couplers include holding devices with holding rings that positively engage with the bellows, providing stable connections while allowing controlled angular movement. This intermediary structure enables the system to handle torque and angular misalignment without damaging the membrane bellows
2Reliability
If the membrane bellows is made more stable and resistant to torque, then reliability improves, but the cost increases
Solution Approach 1:
The third membrane bellows is specifically designed with different properties than the first and second bellows. It is positioned and configured to specifically handle angular misalignment and torque compensation, while the other bellows focus on linear compensation. This localized specialization improves torque resistance where needed without requiring expensive modifications throughout the entire structure
Solution Approach 2:
The bellows couplers with holding devices serve multiple functions: they connect the membrane bellows units, provide positive engagement for stability, allow controlled angular movement for misalignment compensation, and transmit forces between units. This multi-functionality improves reliability without requiring additional expensive components

AI summary
According to various embodiments, a multi-axis compensator comprises: a first mounting device and a second mounting device; a passage which penetrates the first mounting device and the second mounting device along a compensator axis; multiple membrane bellows disposed one behind the other along the compensator axis, of which a first membrane bellows is coupled to the first mounting device and a second membrane bellows is coupled to the second mounting device; at least one bellows coupler which couples the first membrane bellows to the second membrane bellows in such a way that the first membrane bellows and the second membrane bellows run at an angle to each other, so that a passage through the multi-axis compensator, which is curved or angled along the compensator axis, is provided.
