Split Sprocket Slide Tracks for Axial Shifting Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split sprockets lack sufficient resistance to axial shifting during installation in endless belt systems, requiring multiple fasteners or complex assembly processes.
Innovation Solution
The design of split sprockets with mating track elements forming slide tracks allows for secure joining of sprocket sections along these tracks, restricting axial motion and enabling installation without removing bearing blocks, using a single fastener or detent structure for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two screws are used to fasten the split sprocket halves, then the sprocket can be assembled without removing bearing blocks, but the resistance to axial shifting is insufficient
Solution Approach 1:
The invention transitions from axial fastening (screws along the bore axis) to radial fastening (slide tracks perpendicular to the bore axis). The slide tracks extend radially outward from the bore, allowing the sprocket halves to be joined in a direction perpendicular to the bore axis, thereby providing superior resistance to axial shifting while maintaining ease of installation.
Solution Approach 2:
The fastening function is segmented into multiple slide tracks distributed around the bore perimeter. Instead of relying on a single axial fastening element, the invention uses multiple radial slide tracks that collectively provide enhanced resistance to axial shifting forces while allowing straightforward assembly.
2Reliability
If multiple fasteners are used to prevent axial shifting, then reliability improves, but device complexity and assembly process complexity increase
Solution Approach 1:
The invention uses radial slide tracks perpendicular to the bore axis to achieve superior axial shifting resistance with minimal fasteners. The radial orientation of the slide tracks provides mechanical advantage in resisting axial forces while reducing the total number of fastening elements required compared to traditional axial fastening methods.
Solution Approach 2:
The slide track structure combines the guiding and fastening functions into a single integrated feature. The slide tracks serve both to align the sprocket halves during assembly and to provide the primary fastening mechanism that resists axial shifting, eliminating the need for separate alignment and fastening components.
3Device complexity
If traditional axial fastening is used, then assembly is simple, but resistance to axial shifting is insufficient for reliable operation
Solution Approach 1:
The invention maintains assembly simplicity by using a straightforward sliding insertion process while fundamentally improving axial shifting resistance through the radial orientation of slide tracks. The perpendicular fastening direction provides superior mechanical advantage for resisting axial loads compared to traditional axial fastening methods.
Solution Approach 2:
The slide tracks are pre-formed as integral features of the sprocket halves, eliminating the need for separate fastening operations. The sprocket halves are designed with complementary slide track geometries that guide the assembly process and automatically provide the required fastening when the halves are brought together.

AI summary
A split sprocket for belts or chains. The split sprocket comprises two sections that slide together along parallel slide tracks that are perpendicular to two opposite walls of the sprocket's bore. The slide track includes male T-shaped, V-shaped, or jigsaw-puzzle-shaped beams on one of the sections that slide into mating female slots in the other section. The mated slide tracks prevent the sections from separating in all directions except the separation direction along the slide tracks. A fastener through one of the sections into the other prevents the assembled sprocket sections from sliding apart along the slide tracks.
