Clutch Support Member Guide for Grease Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The initial properties of existing clutches used in motor systems, such as those for power window devices, are adversely affected by unevenly applied grease, leading to resistance issues.
Innovation Solution
Incorporating a support member with a guide on its distal surface to evenly distribute grease along the inner circumferential surface of the clutch housing, ensuring the grease is spread and applied uniformly during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If grease is collectively injected into a large space of the clutch housing, then the grease can be applied to all areas, but the grease application becomes uneven and acts as resistance in the initial state
Solution Approach 1:
The support member acts as an intermediary carrier that holds multiple grease reservoirs, enabling controlled and uniform grease distribution to multiple contact surfaces simultaneously, rather than direct injection into the large clutch housing space
Solution Approach 2:
The grease distribution system is segmented into multiple discrete grease reservoirs on the support member, each targeting specific contact areas (inner circumferential surface, drive-side rotation body, driven-side rotation body), ensuring uniform application to each area rather than collective injection
2Reliability
If the support member is designed to hold the rolling element, then the rolling element is properly positioned, but the grease application uniformity is compromised without a guide structure
Solution Approach 1:
The support member is designed with multi-functionality: it holds the rolling element in the correct position while also serving as a grease distribution platform with multiple reservoirs and guide structures, achieving both positioning reliability and grease application uniformity through a single component
Solution Approach 2:
The guide structure on the support member acts as an intermediary that channels grease from the reservoirs along predetermined paths to specific contact surfaces, ensuring uniform application while the support member maintains rolling element positioning
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
This configuration improves the initial properties of the clutch by ensuring even grease distribution, enhancing the motor's performance and facilitating accurate post-manufacturing inspection.
Implementation Method 1
The clutch further includes grease located between the inner circumferential surface of the clutch housing and the rolling element to obtain an appropriate frictional force.

AI summary
A clutch includes a clutch housing, a drive-side rotation body, a driven-side rotation body, a rolling element arranged between an inner circumferential surface of the clutch housing and the driven-side rotation body, a support member, and grease. The support member holds the rolling element between the inner circumferential surface of the clutch housing and the driven-side rotation body. The grease is located between the inner circumferential surface of the clutch housing and the rolling element. The support member includes a guide arranged on a distal surface of the support member. When the grease is unevenly applied to the inner circumferential surface of the clutch housing, the guide is configured to guide the grease to be evenly applied to the inner circumferential surface of the clutch housing when inserted into the clutch housing.
