Solution Overview
Problem
Existing material processing devices face challenges in achieving effective power transmission to the crusher unit while maintaining a compact design.
Innovation Solution
The motor generator is integrated into the drive train between the motor coupling and the crusher unit coupling, with the motor generator shaft being rotationally fixed to both, allowing direct power transmission with reduced power losses in both motor and generator modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the motor generator is installed in the construction area between the motor coupling and the crusher unit coupling, then the design becomes compact and power losses are reduced, but the device complexity increases due to the integrated shaft configuration
Solution Approach 1:
The motor generator is integrated into the drive train between the motor coupling and the crusher unit coupling, merging multiple components into a compact arrangement. The motor generator shaft serves as a common transmission element that connects both couplings, eliminating the need for separate transmission components and reducing power losses through direct power transmission.
Solution Approach 2:
The motor generator shaft performs multiple functions: it transmits mechanical work from the internal combustion engine to the crusher unit in generator mode, and transfers electrical power from the motor generator to the crusher unit in motor mode. This multi-functionality reduces the overall device complexity despite the integrated configuration.
2Loss of energy
If the motor generator shaft is coupled rotationally fixed to both the motor coupling and the crusher unit coupling, then direct power transmission is achieved with low power losses, but the adaptability of the drive train is reduced
Solution Approach 1:
The drive train is designed to be dynamically configurable between two operating modes: generator mode where the internal combustion engine drives the motor generator, and motor mode where the motor generator drives the crusher unit. The rotational fixed coupling allows direct power transmission in both modes while the system adaptability is maintained through mode switching controlled by the motor coupling and crusher unit coupling.
