Tension Torque Support for Drive Trains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional torque supports in drive trains, particularly in industrial transmissions and wind turbines, lead to increased installation space and weight, and fail to effectively decouple vibrations, due to their solid design and reliance on compressive loads and flange connections.
Innovation Solution
A tension torque support system using traction means, such as belts or ropes, that counteracts torque without compressive forces, allowing for decoupling of vibrations and flexible installation without increasing space requirements, by distributing reaction forces across multiple points on the circumference and axis of the transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional solid torque supports or flange connections are used, then torque can be supported, but installation space dimensions and weight increase significantly
Solution Approach 1:
The patent uses a tension element (such as a belt, rope, or flexible membrane) to transmit torque instead of rigid solid connections. This flexible element wraps around the transmission component and transmits torque through tension, dramatically reducing the weight and space requirements compared to conventional solid torque supports while maintaining adequate torque transmission capability
Solution Approach 2:
The invention replaces the conventional mechanical solid connection system with a tension-based flexible element system. This substitution changes the fundamental mechanism from rigid force transmission to flexible tension transmission, achieving weight and space reduction while preserving torque support function
2Force
If conventional solid torque supports are used, then torque can be supported, but installation space dimensions increase
Solution Approach 1:
The tension element (belt, rope, or membrane) wraps around the transmission component in a compact configuration, utilizing the existing circumference of the transmission rather than requiring additional radial or axial space. This flexible approach maintains torque support while fitting within the existing installation envelope
Solution Approach 2:
The tension element is arranged to wrap around and conform to the existing transmission component geometry, effectively nesting the torque support mechanism within the existing space rather than adding external support structures
3Force
If flange connections are used for direct coupling, then torque transmission is direct, but vibration decoupling is not possible
Solution Approach 1:
The flexible tension element inherently provides vibration decoupling through its elastic properties and wrapping configuration. The flexibility of the belt, rope, or membrane allows it to absorb and isolate vibrations while still transmitting torque effectively, eliminating the vibration transmission problem of rigid flange connections
Solution Approach 2:
The tension element acts as an intermediary between the transmission component and the external environment, providing both torque transmission and vibration isolation. This intermediate flexible connection decouples the transmission from direct rigid coupling, allowing vibration attenuation while maintaining power transmission
