Removable Sprocket Tooth Bolted to Ledge for Quick Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprocket assemblies in car wash conveyor systems lack a convenient method for replacing degraded removable teeth, leading to inefficiencies and potential system downtime.
Innovation Solution
A sprocket assembly design featuring a central body with ledge portions and removable teeth with extension portions, where bolts and nuts are used to securely attach the teeth to the sprocket frame, allowing for easy replacement when they become degraded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional sprocket assemblies use fixed teeth that are permanently attached to the sprocket frame, then the structural integrity and strength are improved, but the ease of repair and replacement of degraded teeth deteriorates
Solution Approach 1:
The sprocket assembly is divided into separable components: the sprocket frame and the removable teeth are distinct segments that can be independently replaced. The tooth includes an extension portion with aperture that allows it to be segmented from the main sprocket body while maintaining functional connection through the bolt and ledge portion.
Solution Approach 2:
The degraded tooth can be extracted from the sprocket assembly by removing the bolt from the aperture in the extension portion, allowing the tooth to be taken out and replaced without affecting the entire sprocket frame or other teeth.
2Reliability
If traditional sprocket assemblies use permanently attached teeth, then the reliability of the sprocket is improved, but the loss of time for system downtime when teeth need replacement increases
Solution Approach 1:
The tooth is pre-configured with an extension portion and aperture that enable quick removal and replacement. This preliminary design feature allows maintenance personnel to rapidly swap degraded teeth without complex disassembly procedures, reducing system downtime while maintaining reliability.
3Ease of operation
If sprocket teeth are made removable with extension portions and apertures, then the ease of operation for replacing teeth is improved, but the device complexity increases
Solution Approach 1:
The complexity is localized to specific areas: the extension portion with aperture is only added to the tooth that needs replacement, while the rest of the sprocket frame maintains its simple structure. The ledge portion on the frame provides a localized mounting feature that simplifies the overall assembly process.

AI summary
A sprocket assembly is provided. The assembly includes a sprocket frame having a central body and a first ledge portion body. The first ledge portion has a first aperture extending therethrough. The assembly further includes a first removable tooth having a first tip portion, first and second landing portions, and a first extension portion. The first tip portion has first and second sides and first and second ends. The first extension portion extends from the second end and has an aperture extending therethrough. The assembly further includes a first bolt extending through the first aperture in the first ledge portion and the aperture in the first extension portion to removably couple the first extension portion to the first ledge portion.
