Remotely Mounted Clutch Power Take-Off with Lubricated Spline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power take-off systems face difficulties in installation due to their large or heavy size, making it challenging to mount them on a source of rotational energy, especially when a rotatably driven accessory is remotely positioned.
Innovation Solution
The power take-off system features separate housings for the input mechanism and clutch assembly, connected by a rotatable shaft with a passageway for pressurized fluid, allowing for modular installation and easy positioning of the clutch assembly relative to the input mechanism, facilitating the connection of a rotatably driven accessory at a remote location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power take-off is mounted directly on the source of rotational energy with the accessory positioned remotely using a long shaft, then the accessory can be positioned at a convenient location, but the power take-off becomes relatively large or heavy making installation difficult
Solution Approach 1:
The power take-off is divided into two separate housings: an input mechanism housing mounted on the source of rotational energy, and a clutch assembly housing positioned remotely. This segmentation allows the clutch assembly (which contains the heavy components) to be positioned away from the mounting location, reducing the weight burden at the installation site while maintaining the ability to remotely position the accessory.
2Device complexity
If the input mechanism and clutch assembly are integrated in a single housing, then the structure is compact, but the power take-off becomes large or heavy making installation difficult
Solution Approach 1:
The single housing is segmented into two separate housings connected by a shaft. The input mechanism housing contains only the input mechanism, while the clutch assembly housing contains the clutch assembly. This segmentation distributes the weight, allowing the heavier clutch assembly to be positioned remotely rather than being concentrated at the mounting location.
Solution Approach 2:
A shaft acts as an intermediary element connecting the input mechanism housing to the clutch assembly housing. This shaft transmits rotational power over the distance between the two housings, enabling the separation of components while maintaining functional integration. The shaft allows the clutch assembly to be positioned remotely without compromising power transmission efficiency.
3Ease of manufacture
If the clutch assembly is positioned remotely from the input mechanism, then installation on the source of rotational energy is simplified, but a connection mechanism (shaft) is required between the two housings
Solution Approach 1:
The power take-off is segmented into modular components (input mechanism housing and clutch assembly housing) that can be manufactured and positioned independently. This segmentation simplifies installation by allowing the input mechanism housing to be mounted directly on the source of rotational energy without immediately installing the entire assembly, reducing installation complexity despite adding a connecting shaft.
Solution Approach 2:
The shaft serves as a flexible intermediary that can be adjusted in length and positioning to accommodate different installation configurations. This intermediary element allows the two housings to be positioned at optimal locations while maintaining mechanical connection, facilitating easier installation compared to a rigid integrated structure.

AI summary
A power take-off includes an input mechanism that is disposed within an input mechanism housing and is adapted to be connected to a source of rotational energy. A clutch assembly is disposed within a driveshaft housing and is adapted to be connected to a rotatably driven accessory. A driveshaft connects the input mechanism to the clutch assembly. The driveshaft may be disposed within the driveshaft housing, which also forms a housing for the clutch assembly.
