Spindle Wireless Receiver Tracking for Stable Signal Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The position change of a rotatable member in a rolling mill facility, such as a spindle apparatus, leads to a change in the distance between a transmission part and a reception part, resulting in degraded communication accuracy due to the movement of the rotatable member.
Innovation Solution
A communication device with a reception part guided by a guide part to move along the movement direction of the rotatable member, ensuring accurate signal reception by maintaining a consistent distance with the transmission part, which is integrated with a spindle apparatus that includes a measurement apparatus for temperature and torque measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotatable member is moved to adjust the position of the mill roll, then the position adjustment capability is improved, but the communication accuracy between the transmission part and reception part deteriorates
Solution Approach 1:
The reception part is made movable along the first direction to dynamically track the position of the rotatable member. The guide part enables the reception part to follow the movement of the rotatable member, maintaining optimal communication distance and alignment despite position changes, thus resolving the contradiction between position adjustment capability and communication accuracy
2Measurement precision
If the reception part is made movable to follow the rotatable member, then the communication accuracy is improved, but the device complexity increases
Solution Approach 1:
The guide part is configured to guide the movement of the reception part in a specific direction (first direction) to match the movement of the rotatable member. This localized guidance mechanism maintains communication accuracy without requiring complete freedom of movement, thereby limiting the increase in device complexity while still achieving the desired communication precision
