Hydraulic Roller Adjuster for Position Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling devices face issues with positional stability and reproducibility due to lack of self-locking mechanisms in mechanical adjustment devices, leading to shifts under load and increased space requirements, and hydraulic systems can lose contact, causing encoder position loss and reduced precision.
Innovation Solution
The implementation of a rolling device with two opposing pressure chambers for piston adjustment, a piston rod connected via a lever arrangement, and a sensor integrated into the housing to ensure precise control and prevent position loss, utilizing a hydraulic actuator to adjust the roller's position safely and compactly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mechanical adjustment devices with gears are used, then the roller position can be adjusted, but the device loses the set position under load and requires large installation space
Solution Approach 1:
The patent replaces mechanical adjustment devices with gears with a hydraulic actuator system. The hydraulic cylinder with piston directly adjusts the roller position without mechanical transmission elements, eliminating gear backlash and self-locking issues while maintaining precise position control through direct hydraulic force application.
Solution Approach 2:
The patent employs a hydraulic actuator consisting of a cylinder and piston to provide the adjustment force. The hydraulic system delivers high force with compact dimensions, enabling precise roller position adjustment without the space requirements of mechanical gear systems and without losing the set position under load.
2Manufacturing precision
If mechanical adjustment devices with gears are used, then the roller position can be adjusted, but the installation space and device weight increase
Solution Approach 1:
The patent replaces bulky mechanical gear systems with a compact hydraulic actuator. The cylinder-piston arrangement requires significantly less installation space while providing the same or better position control functionality, directly addressing the space constraint issue.
Solution Approach 2:
Hydraulic actuators are inherently more space-efficient than mechanical gear systems for providing linear adjustment force. The patent's hydraulic cylinder design achieves the required adjustment range and force with minimal installation footprint, reducing both horizontal and vertical space requirements in the rolling device.
3Manufacturing precision
If wedge adjustment devices are used, then the roller position can be adjusted, but the position reproducibility is poor and contact may be lost
Solution Approach 1:
The patent replaces wedge adjustment mechanisms with a direct-acting hydraulic piston system. The piston maintains continuous contact with the roller through controlled hydraulic pressure, eliminating the risk of contact loss that occurs with wedge devices. The hydraulic system provides consistent, reproducible positioning without the mechanical play inherent in wedge mechanisms.
