Rotary Gear Transmission Layout for Easier Gearbox Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary mechanical systems face difficulties in maintenance due to the complex disassembly process required to separate the driving machine and rotary machine, particularly when a transmission is involved, which complicates the process and increases the workload.
Innovation Solution
A rotary mechanical system design that includes a driving machine with a drive shaft, a transmission unit with a main and auxiliary gear system, and a gearbox with spur gears that can be easily disassembled by moving the transmission unit and gearbox apart in the axial direction to release meshing, allowing for maintenance and reassembly without the need for extensive disassembly of the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmission is disposed between the driving machine and the rotary machine, then the rotation speed can be shifted and output, but the maintenance work becomes complex and time-consuming
Solution Approach 1:
The transmission system is divided into modular components: a transmission unit with main and auxiliary gears that can be separated from the gearbox. This segmentation allows the transmission unit to be independently removed for maintenance while leaving the gearbox intact, reducing maintenance complexity despite maintaining rotation speed shifting capability
Solution Approach 2:
The transmission unit (main shaft, auxiliary shaft, and their gears) is extracted as a separate removable module from the gearbox. By taking out the transmission unit, maintenance work can be performed without disassembling the entire gearbox, thus improving ease of repair while preserving the rotation speed shifting function
2Device complexity
If the transmission unit and gearbox are integrated, then the structure is compact, but the disassembly process requires extensive work to separate components
Solution Approach 1:
The integrated structure is segmented into two main parts: the transmission unit and the gearbox. The transmission unit can be quickly separated from the gearbox by simply moving them apart in the axial direction, reducing disassembly time while maintaining a relatively compact overall structure
Solution Approach 2:
The connection between the transmission unit and gearbox is made dynamic rather than fixed. The gears are designed to be easily disengaged by axial movement, allowing the system to transition between integrated and separated states quickly, thus reducing disassembly time

AI summary
A rotary mechanical system includes a driving machine, a transmission unit that includes a main shaft, a main gear, an auxiliary gear meshing with the main gear, an auxiliary shaft, and a first gear, a gearbox that includes a second gear meshing with the first gear, an input shaft with the second gear fixed, and an output shaft that shifts a rotation speed of the input shaft, and a rotary machine that includes a rotary machine shaft connected to the output shaft. The first gear is a spur gear having a plurality of first tooth portions which are spur teeth whose teeth traces are parallel to the central axis. The second gear has a plurality of second tooth portions which are spur teeth whose teeth traces are parallel to the central axis, and each of which is disposed between the adjacent first tooth portions.
