Gear Transmission Lubrication Boxes for Bottom Bearing Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gear transmission units face issues with proper and controllable lubrication of all components, particularly those located in the bottom part, as conventional forced lubrication systems do not ensure consistent delivery due to reliance on gravity for lower components, leading to inefficiencies and complexity in channel network configurations.
Innovation Solution
The integration of lubricant distribution boxes, which are hollow bodies connected to the casing and equipped with inlet and outlet channels, allows for direct forced lubrication of all components, including those in the lowermost parts, by distributing lubricant under pressure through a simplified network of channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If forced lubrication is provided only for uppermost components, then the complexity of the channel network is reduced, but the reliability of lubrication for bottom components deteriorates
Solution Approach 1:
The distribution box acts as an intermediary component that receives lubricant from the channel network and redistributes it to multiple components including bottom components. This mediator enables reliable lubrication of bottom components without requiring complex direct channel routing to each component.
Solution Approach 2:
The lubrication system is segmented into centralized supply (pump and main channels) and decentralized distribution (distribution boxes at various locations). This segmentation allows the main channel network to remain simple while local distribution boxes handle the complexity of reaching all components including bottom ones.
2Device complexity
If gravity-based lubrication is used for bottom components, then the channel network complexity is reduced, but the controllability of lubrication deteriorates
Solution Approach 1:
The distribution box serves as a controlled intermediary that receives pressurized lubricant and actively directs it to bottom components through its own outlet channels. This provides controllability over lubrication delivery to bottom components while keeping the main channel network simple.
Solution Approach 2:
The system uses hydraulic pressure from the pump to force lubricant through the distribution box and its outlets to bottom components. This pressurized fluid delivery provides controllability and reliability without relying on gravity, while the distribution box simplifies the overall channel configuration.
3Reliability
If forced lubrication is extended to all components including bottom ones, then the reliability of lubrication is improved, but the channel network complexity increases
Solution Approach 1:
The lubrication system is divided into centralized supply functions (pump and main channels) and decentralized distribution functions (distribution boxes). This segmentation allows reliable lubrication of all components including bottom ones while keeping the main channel network simple, as the distribution boxes handle local complexity.
Solution Approach 2:
The distribution boxes serve as multi-functional components that perform both reception of lubricant from the main network and active distribution to multiple components including bottom components. This universality allows a single component type to address multiple lubrication needs without increasing overall system complexity.

AI summary
A gear transmission unit, particularly for a motor-vehicle, is provided with a forced lubrication system (3) for lubricating the rolling bearings (B1, B2, B3) and/or further inner components of the transmission unit. The unit is provided with one or more accessory elements in the form of lubricant distribution boxes (S). Each distribution box (S) has a hollow body rigidly connected to the casing (2) of the unit adjacent to a respective channel outlet (5A) which supplies a flow of lubricant under pressure. The hollow body defines an inner lubricant distribution chamber (C) and has an inlet (8) connected to the channel outlet (5A) and two or more outlets (8) connected to further conduits for channels (5B) or chambers, for supplying a flow of lubricant under pressure in parallel to various components to be lubricated inside the transmission casing (2).
