Robot Gear Assembly Jig for Precise Phase Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gear mechanisms for robots face challenges in efficiently aligning the phases of gears, particularly when the installation space is limited and direct access is difficult, requiring multiple jigs and power sources for phase adjustment.
Innovation Solution
A jig with a first gear part and a torque application part that allows for manual phase adjustment of gears by applying torque externally, using a phase indicator to align the gears without power, and a method that facilitates easy assembly by using a single jig for both internal and external gear parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple jigs and power sources are used for phase adjustment, then phase alignment precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple functions (phase adjustment and phase indication) into a single integrated jig. The first gear part with torque application capability and the second gear part with phase indication are merged into one device, eliminating the need for separate adjustment tools and power sources while maintaining alignment precision.
Solution Approach 2:
The jig is designed with multi-functionality to perform both torque application for phase adjustment and phase indication simultaneously. The single jig can operate in different modes (with or without motor assistance) and serves multiple purposes in the gear assembly process, reducing the need for multiple specialized tools.
2Measurement precision
If multiple jigs and power sources are used for phase adjustment, then phase alignment precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent combines multiple functions (phase adjustment and phase indication) into a single integrated jig. The first gear part with torque application capability and the second gear part with phase indication are merged into one device, eliminating the need for separate adjustment tools and power sources while maintaining alignment precision.
Solution Approach 2:
The jig incorporates a phase indication mechanism that automatically displays the gear phase during adjustment. The system provides self-service by indicating the phase position without requiring external measurement tools or complex operation procedures, making the alignment process intuitive and easier to operate.
3Device complexity
If a single jig is used for phase adjustment, then device complexity is reduced, but phase alignment precision may deteriorate
Solution Approach 1:
The jig is designed with multi-functionality to perform both torque application for phase adjustment and phase indication simultaneously. The single jig can operate in different modes (with or without motor assistance) and serves multiple purposes in the gear assembly process, reducing the need for multiple specialized tools.
Solution Approach 2:
The patent introduces a phase indication mechanism as an intermediary element within the single jig. This mediator provides accurate phase information during the adjustment process, ensuring precision is maintained even though only one jig is used instead of multiple specialized tools.
4Ease of operation
If torque is applied manually for phase adjustment, then ease of operation is improved, but power and adjustment capability may deteriorate
Solution Approach 1:
The jig is designed with dynamic adaptability, allowing it to operate in different modes depending on the application requirements. The system can switch between manual torque application (for ease of operation) and motor-driven torque application (for higher power and adjustment capability), making the power level flexible rather than fixed.
Solution Approach 2:
The jig is designed with multi-functionality to perform both torque application for phase adjustment and phase indication simultaneously. The single jig can operate in different modes (with or without motor assistance) and serves multiple purposes in the gear assembly process, reducing the need for multiple specialized tools.

AI summary
A jig includes: a first gear part that can be meshed with an input gear disposed in a casing by being inserted into the casing from the outside of the casing; a torque application part that is fixed to the first gear part, is disposed outside the casing in a state in which the first gear part is meshed with the input gear, and is capable of applying a torque about a first axis, which corresponds to an axis of the first gear part, to the first gear part; and a phase indicator provided on the torque application part to indicate the phase of the first gear part about the first axis.
