Trailer Driveshaft Coupling Alignment for Modular Turbomachinery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in transporting and reassembling large and heavy turbomachinery power generation stations while adhering to road regulations, particularly in aligning and coupling the turbine and generator units to prevent rotor-dynamic issues and minimize heavy lifting, while also requiring a protective cover for transportation.
Innovation Solution
A system comprising a turbine trailer and a generator trailer, each with a driveshaft that can be coupled and decoupled, utilizing guide pins, hydraulic cylinders, and positioners for precise alignment, and a protective cover for the driveshaft that can be easily stowed and deployed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power generation station is separated into multiple trailers for transportation, then the equipment becomes mobile-compliant with road regulations, but the alignment precision of the drivetrain components deteriorates
Solution Approach 1:
The power generation station is divided into separate modular trailers (turbine trailer, generator trailer, etc.) that can be transported independently on roadways. Each trailer is equipped with alignment features including guide pins, receiving sockets, and adjustable positioners that enable precise reassembly at the destination, thus resolving the contradiction between mobility compliance and alignment precision.
2Strength
If heavy lifting equipment is used to couple and decouple the driveshafts, then the coupling strength is sufficient, but the operational complexity and time required increase
Solution Approach 1:
A coupling mechanism with intermediate components including guide pins, receiving sockets, and a coupling device is introduced between the turbine and generator trailers. This intermediary system enables the driveshafts to be coupled and decoupled without heavy lifting equipment, maintaining coupling strength while significantly improving ease of operation and reducing coupling time.
3Reliability
If the protective cover for the driveshaft is permanently installed, then the protection against foreign objects is continuous, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The protective cover is designed as a dynamic component that can be easily installed and removed. It includes features such as a cover body that fits over the driveshaft and can be secured during operation to protect against foreign objects, yet can be quickly removed when assembly or maintenance is required, thus balancing protection reliability with operational ease.

Function Achieved in This Case
Enables the transportation of turbomachinery components in compliance with road regulations, simplifies the assembly process by allowing for easy alignment and coupling of the turbine and generator units, and provides a protective mechanism for the driveshaft during operation.
Implementation Method 1
connecting a first fastening portion of one or more hydraulic cylinders in one of the two trailers to a corresponding second fastening portion in the other one of the two trailers, and pulling the other one of the two trailers towards the one of the two trailers
Implementation Method 2
adjusting one or more hydraulic jacks on the two trailers to achieve drivetrain alignment of the two trailers
Data Source
AI summary
A turbomachinery power generation station can be too large and heavy for transportation. Thus, embodiments are disclosed for separating a full power generation station into road-ready turbine and generator trailers, as well as realigning and recoupling the trailers for operation of the power generation station at a desired destination.
