Collet Liner System for Rock Crusher Concave Ring Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liner retention systems for rock crushers are expensive, complex, and unsafe, requiring excessive time and effort for installation and removal of concave rings.
Innovation Solution
A liner system comprising a collet that applies force to the concave ring and a collet adjuster to lower and raise it, along with link plates and fasteners, simplifies the retention and removal process, reducing cost and complexity while enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional liner retention systems are used, then the concave ring can be retained in the support bowl, but the system becomes expensive, complex, and unsafe with excessive installation and removal time
Solution Approach 1:
The collet is divided into multiple segments that can be independently positioned and adjusted. Each segment can be adjusted via separate adjusters, allowing for simplified assembly and disassembly of the entire liner retention system, directly reducing installation and removal time while maintaining structural integrity
Solution Approach 2:
The collet segments are designed to nest within each other when retracted, and the entire collet assembly nests within the support bowl. This nested configuration reduces the overall complexity of the retention system by eliminating the need for separate retaining components, thereby reducing both device complexity and installation time
2Reliability
If conventional liner retention systems are used, then the concave ring can be retained, but the system becomes expensive and complex
Solution Approach 1:
The retention function is merged into a single integrated collet assembly that combines multiple segments and adjusters into one unified structure. This eliminates the need for separate retaining rings, locks, or fasteners found in conventional systems, reducing device complexity while maintaining reliable retention through the combined action of all collet segments
Solution Approach 2:
The collet assembly serves multiple functions simultaneously: it retains the concave ring, provides adjustable positioning, and enables easy removal. The same structure performs all these functions without requiring additional specialized components, thereby reducing overall system complexity while ensuring reliable retention
3Reliability
If conventional liner retention systems are used, then the concave ring can be retained, but the system becomes unsafe
Solution Approach 1:
The collet assembly is designed to self-lock and self-retain the concave ring through its segmented structure and adjuster mechanism. The system maintains its own position and retention force without requiring external safety devices or complex locking mechanisms, eliminating safety hazards associated with conventional systems while ensuring reliable retention
