Wear Sensing Device for Carrier Roller Track Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wear sensing devices for track assemblies are vulnerable to harsh environments and limited in their ability to measure wear on moving track components, such as track links, while being exposed to mud, water, and ice.
Innovation Solution
A wear sensing device is integrated into a carrier roller assembly, featuring a wear sensor roller mounted to an axle that contacts a track pin assembly, allowing for accurate measurement of wear on track links while being protected from environmental damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wear sensing device is mounted to track links to measure wear directly, then measurement precision is improved, but the device is exposed to harsh environment causing reduced reliability
Solution Approach 1:
The patent introduces a carrier roller assembly as an intermediary between the wear sensing device and the track links. The wear sensor roller contacts the track pin assembly through the carrier roller, allowing wear measurement while the sensor itself remains protected within the carrier roller assembly from direct exposure to mud, water, and ice. This intermediary structure resolves the contradiction by enabling indirect measurement that maintains both precision and reliability.
2Reliability
If the wear sensing device is mounted to track roller assembly to protect from environment, then reliability is improved, but the device cannot measure wear of moving track components
Solution Approach 1:
The wear sensor roller acts as a mediator that transfers the wear measurement function from the protected sensor location to the moving track components. As the carrier roller assembly rotates, the wear sensor roller contacts the track pin assembly, allowing the protected sensor to indirectly measure wear on moving track links through this intermediary contact mechanism.
Solution Approach 2:
The patent replaces direct mechanical mounting of the sensor on moving track links with an indirect mechanical system where the wear sensor roller transfers wear information to the protected sensor. This substitution allows the sensor to remain stationary and protected while still measuring dynamic wear conditions through the intermediary roller mechanism.
