Conveyor Retainer Mechanism for Quick Roller Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor systems require complex and costly assembly processes with threaded fasteners, which are prone to corrosion and maintenance issues in harsh environments, and lack efficient mechanisms for securing idler rollers to support frames.
Innovation Solution
A retaining mechanism using a clip with a first and second portion, where the second portion is biased to exert a compressive force, engaging the shaft of the roller and support frame, allowing for quick assembly and disassembly without the need for specific tools or machining threaded holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded fasteners are used to secure rollers to support frames, then the connection is strong and reliable, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The retainer is divided into a body portion and a separate shaft engagement portion that can be independently positioned and secured. This segmentation allows for simplified assembly where the retainer body is first attached to the support frame, and then the shaft engagement portion is independently secured to the roller shaft, reducing overall assembly complexity while maintaining connection reliability
Solution Approach 2:
The retainer body is pre-secured to the support frame before the roller shaft is installed. This preliminary action allows the retainer to be firmly attached to the frame structure first, and then the roller shaft can be simply engaged with the pre-positioned retainer, significantly reducing assembly time and complexity while ensuring a reliable connection
2Reliability
If threaded fasteners are used to secure rollers, then the connection is durable, but maintenance and repair become difficult in harsh environments
Solution Approach 1:
The retainer incorporates a resilient shaft engagement portion that can dynamically adjust and flex in response to environmental conditions and operational stresses. This dynamic design allows the retainer to maintain its securing function under varying conditions without requiring maintenance, and enables easy removal when repair or replacement is needed, unlike rigid threaded fasteners that may corrode or seize
3Reliability
If complex assembly processes with threaded fasteners are used, then secure attachment is achieved, but manufacturing cost increases
Solution Approach 1:
The retainer combines multiple functions into a single integrated component: it provides structural attachment to the support frame, secures the roller shaft, and incorporates resilient elements for environmental tolerance. This merging eliminates the need for multiple separate fasteners and assembly steps, reducing manufacturing cost while maintaining secure attachment
Solution Approach 2:
The retainer is designed as a universal component that can be used with various roller sizes and support frame configurations. The resilient shaft engagement portion can accommodate different shaft diameters, and the retainer body can be mounted on different frame structures, reducing the need for multiple specialized fastener types and lowering overall manufacturing costs

AI summary
A conveyor support includes a frame, a roller, and a retainer. The frame includes a support arm. The roller includes a shaft and a shell supported for rotation relative to the shaft, and the shaft includes an end. The retainer releasably secures the end of the shaft relative to the support arm. The retainer includes a first portion engaging a first side of the support arm and a second portion engaging a second side of the support arm. The second portion is biased toward the first portion to exert a compressive force on the support arm. At least one of the first portion and the second portion engages the shaft of the roller.
