Overload Limiting Device Torque Adjustment Scale
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional overload limiting devices lack a convenient method to adjust the limiting torque value, as they do not provide a clear indication of the adjustment nut's position, making it difficult to accurately set and adjust the torque limiting value.
Innovation Solution
Incorporating a scale on the first rotation member to indicate the position of the adjustment nut in the rotation axis direction, allowing for easy adjustment of the biasing force and thus the limiting torque value, with features such as grooves, notches, and color differentiation to enhance readability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustment nut is provided to adjust the biasing force of the biasing member, then the limiting torque value can be adjusted, but it becomes difficult to recognize the position of the adjustment nut in the rotation axis direction
Solution Approach 1:
The patent applies color changes by providing a scale with different color regions (first color and second color) that correspond to different position ranges of the adjustment nut. This allows the operator to visually detect the position of the adjustment nut through color differentiation, resolving the difficulty of position recognition while maintaining adjustability.
Solution Approach 2:
The patent introduces a scale as an intermediary element between the adjustment nut and the operator. The scale includes a first region and a second region with different colors, serving as a visual mediator that indicates the position of the adjustment nut in the rotation axis direction, thereby enabling easy position detection.
2Device complexity
If no position indication is provided for the adjustment nut, then the device structure remains simple, but the ease of operation during torque adjustment deteriorates
Solution Approach 1:
The patent incorporates a color-coded scale that can be applied to the first rotation member or housing portion. This color indication system provides visual feedback for the adjustment nut's position without adding complex mechanical structures, thereby maintaining structural simplicity while significantly improving ease of operation during torque adjustment.
Solution Approach 2:
The scale acts as a visual intermediary that bridges the gap between the adjustment mechanism and the operator. By providing a simple visual indication system with different color regions, it enhances operational convenience without complicating the overall device structure.

AI summary
An overload limiting device includes: a rolling element; a rotatable first rotation member having a housing portion that houses the rolling element; a rotatable second rotation member having an engagement recess portion that engages detachably with the rolling element housed in the housing portion, the second rotation member being arranged opposing the first rotation member; a biasing member that biases the rolling element toward the engagement recess portion; and an adjustment nut that adjusts a biasing force of the biasing member by moving in a rotation axis direction of the first rotation member, the adjustment nut being provided to the first rotation member, the first rotation member including a scale showing a position of the adjustment nut in the rotation axis direction.
