Integrated Gearbox Adapter Structure for High-Power Motor Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gearbox adapters are unable to meet the structural strength requirements for high-power motors above 75 KW due to structural limitations.
Innovation Solution
A gearbox adapter with an integrally formed adapter body, a transmission shaft, an opening cover, and multiple bearings is designed to provide the necessary structural strength. The adapter body has a gearbox connection structure and internal cavity with shaft holes and oil chambers for lubrication and sealing, supported by multiple bearings and locking rings to prevent axial movement and ensure coaxiality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a split structure gearbox adapter is used, then the adapter is easier to manufacture and assemble for low-power motors, but the structural strength is insufficient for high-power motors above 75 KW
Solution Approach 1:
The patent merges multiple separate components (adapter body, opening cover, bearings, locking rings) into an integrally formed adapter structure. The adapter body and opening cover are combined with bearings and locking rings to create a unified structure that provides the necessary structural strength for high-power motors while maintaining ease of assembly through integrated design.
2Reliability
If multiple bearings and locking rings are added to increase structural strength, then the adapter can support high-power motors, but the device complexity increases
Solution Approach 1:
The patent segments the adapter into functional modules: the adapter body provides the main structure, bearings provide rotational support, and locking rings provide axial positioning. This segmentation allows each component to perform its specific function efficiently, ensuring connection reliability for high-power motors while maintaining a reasonable level of complexity through functional specialization.
3Manufacturing precision
If an integrally formed adapter body is used, then the structural strength and coaxiality are improved, but the manufacturing difficulty increases
Solution Approach 1:
The patent combines multiple precision components (bearings, locking rings, sealing rings) within the adapter body to achieve high coaxiality. The integral structure ensures precise alignment of the transmission shaft with the gearbox connection structure, improving manufacturing precision for high-power motor applications.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The gearbox adapter effectively connects high-power motors up to 75 KW or more to a gearbox body, ensuring the structural strength requirements are met, and providing improved coaxiality and ease of assembly compared to split structures.
Implementation Method 1
at least one bearing, arranged in the internal cavity (11) and fitted to the transmission shaft (3) to support the transmission shaft (3) and enable the transmission shaft (3) to rotate
Implementation Method 2
the other end of the first bearing (5) being locked by means of a first locking ring (6) installed on the adapter body (1), to prevent the first bearing (5) from moving in the direction of the first locking ring (6)
Implementation Method 3
a first sealing ring (7) is nested in the first shaft hole (14), to seal a gap between the first shaft hole (14) and the transmission shaft (3) by means of the first sealing ring (7)
