Split Sprocket Assembly With Snap-Fit Conveyor Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor drives with split sprockets require fasteners for assembly, increasing manufacturing effort and making replacements difficult, leading to significant downtime and costs.
Innovation Solution
A split sprocket assembly with integral connectors forming a snap-fit engagement, allowing easy assembly and disassembly without tools, using first and second sprocket portions that mate along a drive shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fasteners are used to assemble split sprockets, then the sprocket can be assembled together, but the manufacturing effort and complexity increase significantly
Solution Approach 1:
The patent merges the connector features directly into the sprocket portions themselves, eliminating the need for separate fasteners. The first and second sprocket portions each include integrated connectors that engage with corresponding receivers to assemble the sprocket, combining the fastening function with the structural components.
Solution Approach 2:
The sprocket is divided into multiple portions (first sprocket portion and second sprocket portion) that can be assembled together through the integrated connectors. This segmentation allows for easier manufacturing and replacement while maintaining structural integrity through the connector-receiver engagement system.
2Ease of repair
If traditional fasteners are used to assemble split sprockets, then the sprocket can be assembled together, but the difficulty of replacing worn or damaged sprockets increases
Solution Approach 1:
The sprocket is segmented into replaceable portions with integrated connectors, allowing individual portions to be quickly removed and replaced without requiring disassembly of the entire sprocket assembly. This enables rapid replacement of worn or damaged sections.
Solution Approach 2:
The integrated connectors are designed to enable self-contained assembly and disassembly of the sprocket portions without requiring external fastening tools or complex assembly procedures. The connectors themselves perform the fastening function, allowing for tool-free maintenance operations.
3Ease of operation
If integral connectors with snap-fit engagement are used, then assembly and disassembly become tool-free and quick, but the locking engagement must be reliably released
Solution Approach 1:
The connector-receiver engagement system provides a dynamic locking mechanism that can transition between locked and unlocked states. The snap-fit engagement automatically locks when portions are assembled, and can be deliberately released through the recess and slot mechanism, providing both secure locking and controlled release.
Solution Approach 2:
The recess and slot act as intermediary elements that facilitate the release of the snap-fit engagement. The slot provides a path for the connector to disengage from the receiver, while the recess provides space for the connector to move freely during the release process, enabling controlled disassembly.

AI summary
A split sprocket assembly for connecting to a drive shaft for driving a conveyor chain is disclosed. The split sprocket assembly includes first and second sprocket portions adapted for mating together along the drive shaft. The second sprocket portion includes integral connectors that form a releasable locking engagement with receivers in the first sprocket portion. A method of forming a drive for a conveyor using a drive shaft is also disclosed, which includes forming a releasable locking engagement between first and second sprocket portions over the drive shaft. The releasable locking engagement may be a snap-fit engagement.
