Chain Guide Assembly Frame Oil Routing for Multi-Part Lubrication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chain guide assembly systems inefficiently utilize lubricating oil as they fail to collect and guide oil adhering to parts other than the pivoting chain guide, leading to increased overall oil usage and inadequate lubrication of components like the chain, fixed chain guide, and drive sprocket.
Innovation Solution
A chain guide assembly frame with a main body featuring concave and/or convex oil passages that collect and guide oil from the upper parts to predetermined locations, including the drive sprocket holding portion, fixed chain guide, and pivoting chain guide, ensuring efficient lubrication with reduced oil amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If oil is supplied to all parts of the chain guide assembly without collection and guidance structures, then sufficient lubrication can be achieved, but the overall amount of oil required increases
Solution Approach 1:
The chain guide assembly is divided into multiple functional parts (fixed chain guide, pivoting chain guide, drive sprocket, driven sprocket), each with dedicated oil collection and guidance structures. This segmentation allows oil to be efficiently distributed to each component individually, ensuring sufficient lubrication while minimizing the total oil quantity required.
Solution Approach 2:
Oil collection grooves and guidance structures act as intermediaries between the oil supply source and the various lubrication points. These intermediary structures collect oil from the engine inner wall and systematically guide it to predetermined locations, enabling efficient oil utilization across all components.

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 allows for effective lubrication of various parts within the chain guide assembly using a reduced amount of oil, improving the lubrication efficiency and durability of the drive sprocket, fixed chain guide, and pivoting chain guide.
Implementation Method 1
a concave and/or convex oil passage extending from an upper part toward a lower part to guide oil toward above the drive sprocket holding portion

AI summary
To provide a chain guide assembly frame capable of efficiently collecting the oil that adhered to various parts of the chain guide assembly, and guiding the collected oil to predetermined locations, to allow efficient use of oil, with a simple structure. The chain guide assembly frame includes driven sprocket holding portions, a fixed chain guide, and a pivoting chain guide holding portion on a main body. A drive sprocket holding portion is provided at a position lower than the driven sprocket holding portions. The main body includes a concave and/or convex oil passage that extends from an upper part toward a lower part to guide the oil toward above the drive sprocket holding portion.
