Elastic Junction for Sliding Block Adapter Axial Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding block adapter systems in rolling plants transmit axial loads from the rolling stand to motors, causing stress and potential failure, as they lack elastic and pluridirectional response to manage these loads effectively, leading to oversized and costly motor bearings to prevent shutdowns.
Innovation Solution
An elastic junction for sliding block adapters featuring a central pin with multiple sliding blocks and interfaced dampers, allowing controlled axial load transmission, acting like a spring to absorb and manage axial stresses, thereby reducing the load transmitted to the motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid adapter junctions are used to ensure structural stability, then the adapter maintains structural integrity, but axial loads are transmitted to the motor causing bearing stress and potential failure
Solution Approach 1:
The patent changes the mechanical parameter of the junction from rigid to elastic by introducing spring elements. This allows the junction to maintain structural integrity while dynamically absorbing axial loads through elastic deformation, preventing load transmission to the motor bearings.
Solution Approach 2:
The patent introduces an intermediary elastic element (spring) between the adapter junction and the motor. This intermediary component absorbs axial loads through elastic deformation, acting as a mediator that protects the motor from direct load transmission while maintaining structural connectivity.
2Reliability
If motor bearings are oversized to withstand axial loads, then motor reliability is improved, but the size and cost of the motor system increases substantially
Solution Approach 1:
The patent applies beforehand cushioning by installing elastic elements at the adapter junction before axial loads are transmitted to the motor. These elements pre-absorb and dampen axial loads, cushioning the motor bearings from excessive stresses and allowing the use of appropriately sized, cost-effective bearings.
3Object-affected harmful factors
If elastic elements are introduced to absorb axial loads, then load transmission to motor is reduced, but the complexity of the adapter system increases
Solution Approach 1:
The patent applies segmentation by dividing the adapter junction into modular components with integrated spring elements. This segmentation allows the elastic load-absorbing function to be incorporated as a distinct, manageable module, reducing overall system complexity while maintaining load reduction benefits.
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
The solution significantly reduces axial loads transmitted to the motor by up to 50% compared to prior art, enabling the use of smaller axial bearings and preventing motor failure, thus minimizing production downtime and costs.
Implementation Method 1
whose rectilinear motion takes place along the longitudinal axis of the adapter. This frictional non-rotatable connection is coupled to the outer cylindrical dampers which absorb the axial forces and prevent the twisting of the two interconnected segments of the adapter
Implementation Method 2
The inner cylinders consist of a guiding jacket within which a sliding damper element can move, whose rectilinear motion takes place along the longitudinal axis of the adapter. This frictional non-rotatable connection

AI summary
The elastic junction for the dynamic connection between the motor side and the head of a sliding block adapter, or between adapter and rolls of a rolling plant, comprises a central pin (5) arranged perpendicular to the longitudinal axis of the adapter (3), multiple sliding blocks (4) connected by means of the pin (5) to the adapter (3), a block (1) fixed to the flange (2) and two interfaced and complementary series of dampers (6) connected to the pin (5). This ensures the reduction of the axial tensions which are transmitted along the adapter in response to stresses caused by rolling.
