Bearing-Supported Transport Lock for Planet Carrier Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transport locks for wind turbine gearboxes fix the planet carrier rigidly during transport, preventing relative movement and making it difficult to align the planet carrier with other components, which can lead to stationary damage and complex assembly processes.
Innovation Solution
A transport lock comprising two joinable parts, one attached to the housing-fixed component and the other to the planet carrier, with at least one bearing allowing the parts to be rotatably supported in each other, enabling the planet carrier to be rotated relative to the housing-fixed component during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the planet carrier is fixed rigidly in the housing during transport, then the planet carrier is securely held in a defined position, but it becomes difficult to align the planet carrier with other components and may cause stationary damage
Solution Approach 1:
The transport lock is designed with two parts that can rotate relative to each other through a bearing, transitioning from a static rigid connection to a dynamic adjustable connection. This allows the planet carrier to be rotated and aligned during transport while maintaining positional stability when needed.
Solution Approach 2:
A bearing is introduced as an intermediary element between the first part (attached to housing) and the second part (attached to planet carrier). This bearing enables relative rotation while maintaining the connection, serving as a mediator that allows alignment adjustments without compromising the secure holding function.
2Reliability
If the planet carrier is fixed rigidly during transport, then the planet carrier is securely held, but the assembly process becomes complex and may require twisting the shaft
Solution Approach 1:
The transport lock allows dynamic adjustment during assembly by enabling rotation of the planet carrier relative to the housing through the bearing mechanism. This eliminates the need for complex twisting operations or shaft adjustments that would otherwise be required to achieve proper alignment.
Solution Approach 2:
The bearing acts as a mediator that simplifies the assembly process by providing a built-in rotation mechanism. Instead of requiring external twisting operations on the shaft or complex alignment procedures, the bearing enables direct rotation of the planet carrier into the correct position.
3Device complexity
If the transport lock uses a rigid connection, then the structure is simple, but it prevents rotation and alignment of the planet carrier
Solution Approach 1:
A bearing is introduced as a relatively simple intermediary component that provides rotation capability without significantly complicating the overall structure. The bearing enables the planet carrier to rotate and align while maintaining a straightforward two-part transport lock design with clear attachment points to the housing and planet carrier.

Function Achieved in This Case
This solution allows for the avoidance of stationary damage during transport by enabling the planet carrier to be rotated and aligned properly, simplifying the assembly process and eliminating the need for twisting the shaft, which can be effort-intensive or impossible.
