Ship Torque Transmission Separate Clutch Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ship torque transmission devices suffer from dynamic influences and lengthened power trains due to common housings for clutches and gear units, leading to increased bearing friction, noise, and inefficient use of space.
Innovation Solution
A torque transmission device with separate gear unit and clutch housings, where the clutches are positioned on the forward side of the ship, allowing for decoupling of clutch and gear unit functions, reducing power loss, and enabling a more compact design by shortening the force flow and reducing propeller shaft loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If clutches and gear units are arranged in a common housing, then space utilization is improved, but dynamic influences increase and power loss due to bearing friction increases
Solution Approach 1:
The patent divides the torque transmission device into separate housings: a clutch housing for clutches and a gear unit housing for the gear unit. This segmentation isolates the dynamic influences of clutch engagement from the gear unit, reducing bearing friction and power loss while maintaining compact overall design.
2Device complexity
If clutches and gear units are arranged in a common housing, then device complexity is reduced, but dynamic influences from clutches burden the gear unit
Solution Approach 1:
The patent separates clutches and gear units into different housings to isolate dynamic influences. The clutch housing contains engagement dynamics while the gear unit housing provides a stable mounting environment, improving reliability without significantly increasing overall device complexity.
3Ease of manufacture
If clutches and/or auxiliary drive are arranged at the back side of the ship, then assembly is simplified, but the power train becomes correspondingly lengthened
Solution Approach 1:
The patent relocates the clutch housing and auxiliary drive to the forward side of the gear unit housing, utilizing the axial dimension differently. This arrangement shortens the power train length by positioning components in a more compact axial configuration while maintaining assembly feasibility.
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 reduces power loss, noise, and enhances space utilization, providing a more efficient and compact marine propulsion unit capable of handling high torque loads while minimizing mutual influences between the gear unit and clutches.
Implementation Method 1
The first clutch (14) and second clutch (15) are each constructed in particular as engaging and disengaging separating clutches, for example, as multi-disk clutches or dry friction clutches

AI summary
A torque transmission device for a ship for optionally transmitting a drive torque from a main drive or from an auxiliary drive to a propeller shaft of the ship, with a gear unit which can be driven by the main drive and which can be connected to the propeller shaft by a first clutch, and with a second clutch by which the auxiliary drive can be connected to the propeller shaft. The gear unit is received in a gear unit housing, the first clutch and/or second clutch are/is received in a clutch housing that is separate from the gear unit housing, and the first clutch, the second clutch and/or the auxiliary drive are arranged on the side of the gear unit remote of a propeller.
