Wear Pad Mount Locking for Abrasion-Resistant Face Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection systems for machinery faces, such as conveyor chutes and excavator buckets, face issues with wear pad loosening due to abrasive wear and movement, leading to increased wear rates and maintenance challenges.
Innovation Solution
A protection system featuring a mount with complementary engagement means and a locking member that allows relative sliding movement between the mount and wear pad, secured with bolts, and includes wear indication means to facilitate timely replacement, preventing sliding movement and ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If wear pads are removably mounted on mounts using locking mechanisms, then ease of replacement is improved, but reliability deteriorates due to loosening from abrasive wear and movement
Solution Approach 1:
The wear pad is pre-formed with protrusions that engage with recesses in the mount before final locking occurs. This preliminary mechanical interlocking action ensures proper positioning and initial security of the wear pad on the mount, preventing loosening during operation while maintaining ease of replacement.
2Reliability
If wear pads are securely locked to mounts, then reliability is improved by preventing loosening, but device complexity increases due to additional locking mechanisms
Solution Approach 1:
The locking mechanism is merged with the basic mounting structure by integrating protrusions on the wear pad that directly engage with recesses in the mount. This combination eliminates the need for separate complex locking components, achieving secure attachment while minimizing device complexity.
3Adaptability or versatility
If wear pads are allowed to move relative to mounts, then adaptability is improved for different wear patterns, but reliability deteriorates due to increased wear rates from loosening
Solution Approach 1:
The wear pad is designed with specific protrusions at localized positions that engage with corresponding recesses in the mount. This local engagement feature provides secure attachment at critical points while allowing the overall wear pad to accommodate different wear patterns and orientations, balancing adaptability with reliability.

AI summary
A protection system includes a mount for attachment to a wear panel of equipment. The mount includes a first portion which engages the wear panel to be protected and a second portion extending from the first portion which engages an adjacent face to be protected. The second portion has a passage which allows sliding movement of a bolt along the passage. A wear part is releasably mounted to the mount and has a first portion that slidingly engages the first portion of the mount and a second portion that engages the second portion of the mount. The second portion of the wear part has a passage arranged to align with the passage through the second portion of the mount when the wear part and the mount are engaged. A bolt extends through the aligned passages to secure the wear part to the mount via a locking member.
