Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing torque supports in calender or rolling mill drives introduce retroactive forces and affect the accuracy of the system by altering the angular position of rolls, and designs with two external coupling points fix the drive in position, preventing full compensation for movements.

Innovation Solution

A torque support system with rotatable bearings that transmit torque as tensile or compressive forces, using first and second force-conducting elements fixed to a support element, allowing the support element to move freely and maintain roll position without introducing additional forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a one-sided torque support is used to absorb drive torques, then the torque can be intercepted by the torque support acting as a lever arm, but retroactive forces are introduced into the bearing arrangement that force the roll out of its position and affect system accuracy

Engineering Contradiction:

Improvetorque absorption capabilityVSAvoidroll position accuracy

Core Design Contradiction:

ForceVSManufacturing precision

Solution Approach 1:

The torque support is divided into two separate torque supports arranged opposite to each other, each absorbing torque in opposite directions. This segmentation allows the retroactive forces from each support to counterbalance each other, eliminating the net retroactive force that would otherwise affect roll position accuracy while maintaining effective torque absorption capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The two torque supports are arranged as counterbalancing elements opposite to each other, where one torque support acts as a counterweight to the other. The retroactive forces generated by each support counterbalance each other, neutralizing the harmful effect on roll position while preserving the torque absorption function

Inventive Principle:

Principle #8Anti-weight (Counterweight)

2Manufacturing precision

If two external coupling points are used to absorb torque from opposite sides of the drive, then no retroactive force is introduced to the bearing or drive, but the drive is fixed in its position both rotationally and linearly and cannot completely compensate for movements acting on it

Engineering Contradiction:

Improvedrive position stabilityVSAvoidmovement compensation capability

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The coupling between the torque supports and the drive is made dynamic through rotatable connections rather than rigid fixed connections. This allows the drive to rotate freely and compensate for movements while the torque supports continuously absorb torque, maintaining both position stability and movement compensation capability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the coupling parameter from rigid fixed connection to rotatable connection, allowing the drive to adapt its angular position while the torque supports maintain torque absorption. This parameter change enables the drive to compensate for movements while maintaining stability

Inventive Principle:

Principle #35Parameter changes
