Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque arm structures for gear motors in large-sized movable devices, such as cranes and conveyor belts, face maintenance challenges due to the difficulty in removing and replacing elastic members, which affects the structure's ability to absorb impact loads and maintain the gear motor's angular position.
Innovation Solution
A torque arm structure comprising a first member fixed to the reduction gear, a second member attached to an outer member, and an elastic member that transmits loads between them, allowing for easy detachment and replacement of the elastic member, thereby simplifying maintenance and improving the structure's ability to absorb impact loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the elastic member is fixed between the first member and the second member using bolts, then the structural integrity is improved, but the maintenance complexity increases due to precise bolt positioning and fastening torque management requirements
Solution Approach 1:
The elastic member is divided into multiple independent elastic elements (first elastic element, second elastic element, third elastic element) that can be independently installed and removed. Each elastic element is fitted into a separate gap between corresponding members, allowing maintenance without affecting the entire structure. This segmentation enables easy replacement while maintaining structural integrity through distributed load bearing.
Solution Approach 2:
The elastic member is extracted from a permanently fixed state to a detachable state. The elastic member is fitted into gaps and can be easily removed and reinstalled without bolts or fastening operations. This extraction of the fastening requirement allows maintenance personnel to simply insert and remove the elastic member to replace it, eliminating the need for torque management and precise positioning.
2Reliability
If the elastic member is permanently fixed between members, then the reliability of the torque arm structure is improved, but the time required for maintenance and replacement increases
Solution Approach 1:
The elastic member is pre-formed with a specific shape and elasticity that allows it to be directly fitted into the gaps between members. The preliminary preparation of the elastic member with appropriate mechanical properties enables quick installation and removal without requiring complex assembly procedures, thereby reducing maintenance time while ensuring reliable torque arm functionality.
Solution Approach 2:
The elastic member transitions from a static, permanently fixed component to a dynamic, detachable component. The elastic properties of the member allow it to be easily inserted and removed while maintaining its load-bearing function during operation. This dynamic characteristic enables quick maintenance replacement without compromising the reliability of the torque arm structure during normal operation.
3Stability of the object's composition
If complex fastening structures are used to secure the elastic member, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The elastic member utilizes its own elastic properties to secure itself between the first member and the second member, as well as between the second member and the third member. The member is fitted into the gaps and maintains its position through elastic deformation and mechanical interference, without requiring external fastening structures. This self-service mechanism simplifies the overall device complexity while ensuring structural stability through the elastic member's inherent mechanical properties.

AI summary
A torque arm structure includes a first member which is fixed to the reduction gear or a member integrated with the reduction gear, and a second member which is fixed to an outer member to oppose the first member, and an elastic member configured to transmit a load by which the reduction gear is rotated around the output shaft from the first member to the second member. The elastic member is to be fitted into a gap between the first member and the second member and is detachably disposed in the gap.
