Rotor Drive Axial Positioning Adjustment Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing open-end spinning devices have complex assembly and adjustment processes, requiring solid rotor housings and necessitating the dismantling of the entire device to replace the drive, which is time-consuming and inefficient.
Innovation Solution
A method for adjusting the axial position of the drive in relation to the cover element using a setting gauge and a sensor, allowing for precise positioning without disassembling the device, with the drive mounted on a carrier that can be easily removed and reassembled, and a mechanical or electronic measuring head to measure the distance between the setting gauge and the rotor shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the drive is integrated into a solid rotor housing, then the stability of the device is improved, but the complexity of assembly and adjustment increases
Solution Approach 1:
The device is divided into separate functional modules: the drive unit can be independently removed from the rotor housing, and the rotor housing is separated into a main body and a cover element. This segmentation allows the drive to be replaced without dismantling the entire rotor housing, reducing assembly complexity while maintaining structural stability.
2Stability of the object's composition
If the rotor housing is made very solid to ensure stability, then the stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The drive unit is extracted as a separate replaceable component from the rotor housing. The cover element can be removed to access and replace the drive without dismantling the solid rotor housing structure, enabling easy repair while maintaining the stability provided by the solid housing.
3Ease of manufacture
If the drive is replaced from the rear requiring dismantling of the rotor housing, then the manufacturing simplicity is improved, but the loss of time increases
Solution Approach 1:
The cover element is pre-designed to be removable, providing preliminary access to the drive unit. This preliminary action eliminates the need for complete dismantling during drive replacement, significantly reducing the time required for maintenance while keeping the manufacturing process simple.
4Manufacturing precision
If a setting gauge and sensor are used to measure the distance between the rotor housing and cover element, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The mechanical measurement and adjustment process is replaced with an optical/electronic measurement system using a sensor and setting gauge. This substitution provides precise digital measurement of distances and positions, enabling accurate positioning of the drive relative to the rotor housing and cover element, while the modular design keeps the overall device complexity manageable.
