Machine Tool Damper Alignment for Non-Parallel Vibration Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools with vibration dampers oriented parallel to side faces are not effective in damping vibrations that are not parallel to these surfaces, leading to suboptimal performance.
Innovation Solution
The machine tool design includes vibration dampers oriented such that their damping directions are neither parallel nor parallel to the side surfaces, with the option to adjust their orientation, allowing for decoupling and enhanced damping behavior through active vibration damping, and the ability to operate with or without the dampers based on application needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vibration dampers are oriented parallel to the side faces, then the structure is simple and manufacturing is easy, but vibrations that are not parallel to these surfaces cannot be effectively damped
Solution Approach 1:
The patent applies the dynamics principle by making the vibration dampers adjustable in orientation rather than fixed. The dampers can be positioned at different angles relative to the side faces, allowing the system to adapt to various vibration directions. This dynamic adjustment capability resolves the contradiction by enabling effective damping of non-parallel vibrations while maintaining a relatively simple structural implementation.
2Reliability
If vibration dampers are oriented neither parallel to side surfaces, then non-parallel vibrations can be damped effectively, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the orientation angle parameter of the vibration dampers. Instead of using complex multi-axis dampers, the solution changes the angular parameter of simple damper units to match the vibration direction. This allows effective damping of non-parallel vibrations while keeping the damper structure itself simple, thus resolving the contradiction between effectiveness and complexity.

AI summary
A machine tool comprises at least a first and a second machine element (6, 2). The first machine element (6) is guided in a guide of the second machine element (2) and can be moved in a position-controlled manner in a travel direction (z) by means of a drive (4) of the machine tool within the guide of the second machine element (2). The first machine element (6) has a first and a second side surface (11, 12) that are parallel to the travel direction (z) and orthogonal to each other. The machine tool comprises a first and a second vibration damper (13, 14), by means of which a vibration of the first machine element (6) propagating in a respective vibration direction (F1, F2) can be damped. The vibration directions (F1, F2) are oriented orthogonal to the travel direction (z).The first vibration damper (13) and/or the second vibration damper (14) are oriented such that the direction of vibration (F1, F2) of the vibration that can be damped by means of the first or second vibration damper (13, 14) alone is neither parallel to the first nor parallel to the second side surface (11, 12).
