Gas Laser Blowing Section Rotary Part Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas laser oscillators require frequent replacement of the blowing parts, particularly the bearings, which is costly and time-consuming due to the need for disassembly and recalibration, limiting cost-effectiveness in routine inspections.
Innovation Solution
The gas laser oscillator design allows for the detachment and replacement of only the rotary part of the blowing section, eliminating the need to replace the entire blowing section during routine inspections, with a tapered joint system enabling easy assembly and disassembly of the rotary and non-rotary parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire blowing section is replaced during routine inspections, then the reliability of the gas laser oscillator is maintained, but the cost and time required for maintenance increase significantly
Solution Approach 1:
The blowing section is divided into a rotary part and a non-rotary part that can be detached from each other. The rotary part containing the impeller and motor can be replaced independently during routine inspections, while the non-rotary part remains in place. This segmentation allows for quicker maintenance without requiring complete disassembly of the blowing section, thus reducing maintenance time while maintaining reliability.
Solution Approach 2:
The rotary part is extracted as a separate replaceable component from the blowing section. By taking out only the necessary rotary components that require maintenance rather than replacing the entire blowing section, the maintenance process becomes more efficient and less time-consuming while still ensuring the reliability of the gas laser oscillator.
2Reliability
If the entire blowing section is replaced during routine inspections, then the reliability of the gas laser oscillator is maintained, but the maintenance cost increases
Solution Approach 1:
The blowing section is segmented into replaceable rotary part and stationary non-rotary part. This allows only the necessary rotary components to be replaced during routine inspections, reducing material consumption and maintenance costs while maintaining the reliability of the gas laser oscillator through targeted component replacement.
Solution Approach 2:
Instead of discarding the entire blowing section, only the worn rotary part is discarded and replaced, while the non-rotary part is recovered and retained for continued use. This reduces maintenance costs by minimizing the amount of material that needs to be replaced while still ensuring system reliability.
3Ease of repair
If the rotary part is made detachable from the non-rotary part, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The blowing section is segmented into detachable rotary and non-rotary parts, improving ease of repair by allowing independent replacement of the rotary part. The complexity increase is minimized by using a simple tapered joint system with key-way engagement that provides secure connection without requiring complex coupling mechanisms.
Solution Approach 2:
Instead of making the entire blowing section fixed and non-replaceable, the invention makes the rotary part detachable and replaceable. This inversion of the traditional fixed design improves ease of repair while the simplicity of the tapered joint mechanism keeps the added complexity minimal.

Function Achieved in This Case
This approach reduces the cost and time required for routine inspections by minimizing the components replaced, thereby enhancing the cost-performance of the gas laser processing machine.
Implementation Method 1
Supply of AC power from the outside to motor-stator 926 generates a rotary magnetic field, which rotates rotor 922, thereby rotating impeller 924 via shaft 923
Implementation Method 2
the rotation of impeller 924 thus generates laser gas flow 909
Implementation Method 3
The laser gas then generates electric discharge in discharge space 905 from electrodes 902 and 903. The excited laser gas then is optically resonated by the optical resonator
Implementation Method 4
The excited laser gas then is optically resonated by the optical resonator formed of total reflection mirror 906 and partial reflection mirror 907

AI summary
A gas laser oscillator includes a discharge section for exciting laser gas, a blowing section for transmitting the laser gas, and a laser gas flowing path for forming a circulation route of the laser gas between the discharge section and the blowing section. The blowing section is formed of a rotary part to be rotated by a shaft driver and a non-rotary part not to be rotated. The rotary part includes a rotary shaft to which an impeller is mounted at an end, the shaft driver for rotating the rotary shaft, an upper bearing and a lower bearing coupled to the rotary shaft. The rotary part is detachable from the non-rotary part.
