Robot Reduction Gear Support Jig for Precise Replacement Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for replacing reduction gears in robots are inefficient, requiring heavy machinery to move and position the gears, which can be cumbersome and unsafe due to the weight and size of the components.
Innovation Solution
A jig system that includes a fixed portion detachably attached to a robot element, a movable portion for rotational and linear movement, and a support mechanism to suspend the reduction gear in the gravity direction, allowing the operator to move the gear closer to or away from an attachment point without using heavy machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If heavy machinery is used to move and position the reduction gear, then the gear can be moved despite its weight and size, but the operation becomes cumbersome and unsafe
Solution Approach 1:
The support mechanism suspends the reduction gear in the gravity direction, using gravitational force beneficially to hold the gear rather than fighting against it. This allows the heavy gear to be supported without requiring heavy machinery for positioning.
Solution Approach 2:
The jig acts as an intermediary device between the operator and the heavy reduction gear. The jig includes a support that suspends the gear and a movable portion that the operator can easily manipulate to position the gear, eliminating the need to directly handle the heavy component.
2Manufacturing precision
If heavy machinery is used to move the reduction gear, then the gear can be positioned accurately, but the complexity and cost of the equipment increases
Solution Approach 1:
The jig serves as a simple intermediary tool that provides precise positioning capability without the complexity of heavy machinery. The fixed portion attaches to the robot element, the support suspends the gear, and the movable portion allows easy adjustment, achieving precise positioning with minimal complexity.
Solution Approach 2:
The positioning system is segmented into three simple functional parts: a fixed portion for attachment, a support for suspending the gear, and a movable portion for positioning. This segmentation allows each part to perform its function simply while collectively achieving precise positioning.
3Ease of operation
If the reduction gear is handled directly by operators, then the operation is simple, but the gear cannot be safely moved due to its weight and size
Solution Approach 1:
The jig is introduced as an intermediary tool that the operator controls easily while it handles the heavy gear safely. The operator manipulates the lightweight movable portion to position the gear, while the support mechanism bears the weight and ensures safe handling throughout the replacement process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the efficiency and safety of reduction gear replacement by enabling the operator to manage the gear's position and orientation more easily, reducing the need for heavy machinery and improving the overall replacement process.

AI summary
There is a demand for further improving efficiency of a task of replacing the reduction gear of the robot. A jig configured to support a reduction gear connecting a first element and a second element of a robot to be enabled to perform a speed reduction operation on each other, when the second element is separated from the first element includes a fixed portion removably mounted to the first element or the second element, a movable portion rotationally or translationally movably mounted to the fixed portion, and a support mounted to the movable portion and configured to suspend and support the reduction gear in a gravity direction.
