Rotary Machine Gear Baffle Plate Oil Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rotary machines with gear trains, the adhesion of drain oil to the gear wheel causes significant power loss, particularly in high-power systems, as existing solutions only prevent adhesion to the upper half of the gear wheel, leaving the lower half vulnerable to oil adhesion and resulting power loss.
Innovation Solution
The implementation of baffle plates positioned between the bearing sections and the gear wheel to prevent drain oil from adhering to the gear wheel, with specific configurations for the lower and upper halves, and additional plates for driven shaft bearings, guiding oil away from the gear wheel to reduce power loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If covers are provided on both sides of the pinion gear bearing to prevent drain oil adhesion to the upper half of the gear wheel, then adhesion to the upper half is prevented, but adhesion to the lower half is not prevented causing power loss
Solution Approach 1:
The gear wheel protection is segmented into upper and lower half portions, with different protective measures applied to each. The first plate specifically addresses the lower half portion that was previously unprotected, while the second plate addresses the upper half portion. This segmentation allows targeted protection where needed most.
Solution Approach 2:
Baffle plates (first and second plates) are introduced as intermediary elements between the pinion gear bearing and the gear wheel. These plates act as mediators that intercept and redirect drain oil away from the gear wheel surfaces, preventing direct contact and adhesion without requiring complete enclosure.
2Object-affected harmful factors
If the first plate extends further downward than the gear wheel lower end, then drain oil adhesion prevention is enhanced, but device complexity increases
Solution Approach 1:
The first plate extends in the axial direction beyond the gear wheel lower end, utilizing the unused spatial dimension below the gear wheel. This extension creates an additional protection zone without interfering with the normal rotation or operation of the gear wheel, effectively preventing oil adhesion while maintaining operational simplicity.

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 solution effectively reduces power loss by preventing drain oil from adhering to the gear wheel, allowing for a rotary machine that requires less power during operation by directing and separating the oil from the gear wheel's surfaces.
Implementation Method 1
drain oil discharged from the bearing section is prevented from falling and adhering onto the lower half portion of the gear wheel by the first plate
Implementation Method 2
a bearing section which rotatably supports the driving shaft and is supplied with lubricating oil

AI summary
A rotary machine characterized by being equipped with: a rotary drive part; a drive shaft that is rotated about a horizontally extending axis by the rotary drive part; a large gear that is fixed to the drive shaft; a bearing part that rotatably supports the drive shaft, and to which a lubrication oil is supplied; multiple pinions that are driven by being engaged with the large gear; multiple compression parts that are arranged so as to correspond to the multiple pinions and are respectively rotated by the pinions; and a plate that is installed between the bearing part and the large gear and covers at least a portion of the bottom half of the large gear so as to separate the large gear and the bearing part from each other.
