Flange Gear Coupling for Overload-Protected Transmission Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission systems are difficult to assemble and lack protection against overloading, particularly in applications like robot arms where sudden load peaks can occur.
Innovation Solution
A transmission system designed with a flange gear and an elastically deformable coupling component that connects to a counter flange, allowing for easy assembly and decoupling from load peaks, featuring a rotationally fixed connection that can be released without damage for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gear is rigidly fixed to the torque support element, then the transmission system has high structural stability, but it cannot protect against short-term load peaks and requires complex assembly procedures
Solution Approach 1:
The coupling component changes its stiffness parameter dynamically: under normal operating conditions it maintains a rigid connection for structural stability, but under overload conditions it becomes flexible to absorb load peaks. This is achieved through the elastic element that can deform when subjected to excessive forces, thereby protecting the gear from damage while simplifying assembly compared to rigid fixation methods.
2Strength
If the gear is rigidly fixed to the torque support element, then the connection is strong, but the assembly procedure becomes difficult and time-consuming
Solution Approach 1:
The coupling component is segmented into distinct functional elements: a first connection element for attaching to the gear, a second connection element for attaching to the torque support element, and an elastic element connecting these two. This segmentation allows each part to be manufactured and assembled independently, simplifying the overall assembly process while maintaining strong connections through the specialized connection elements.
3Stability of the object's composition
If the gear is firmly attached to the torque support element, then the transmission system has high structural stability, but maintenance requires destructive disassembly
Solution Approach 1:
The coupling component transitions from a static rigid connection to a dynamic可拆卸 connection. The first and second connection elements are designed to be detachably connectable, allowing the gear to be firmly attached during operation for structural stability, but easily separated during maintenance without destructive forces. The elastic element maintains the firm connection during operation but allows for clean separation when needed.
4Reliability
If a rigid coupling is used between the gear and torque support element, then the connection is stable, but it cannot decouple from load peaks
Solution Approach 1:
The elastic element acts as an intermediary between the first connection element (attached to the gear) and the second connection element (attached to the torque support element). This intermediary component absorbs and isolates the effects of load peaks, preventing them from being directly transmitted to the gear while maintaining the overall connection. This simplifies the coupling structure compared to more complex shock-absorbing mechanisms.

AI summary
The invention relates to a transmission system comprising a torque support element and a three-shaft transmission, which has at least one gear, in particular annular gear. The transmission system is characterized in that the gear is designed as a flange or has a flange, and that the gear is fixed to the torque support element by means of an elastically deformable coupling component, which has a counter flange non-rotatably connected to the flange.
