Drive Roller Axial Coupling for Conveyor Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor systems face difficulties in quickly and easily removing drive rollers for maintenance or replacement due to complex configurations and connections with drive means, particularly in belt conveyor systems where the belt is wound around the drive roller.
Innovation Solution
The drive roller assembly incorporates coupling means with a first and second coupling member for axial engagement and disengagement, allowing for easy detachment from the support structure by releasing the axial engagement of the shaft and drive means, enabling quick removal and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive roller is firmly connected to the drive means for reliable power transmission, then the reliability of power transmission is improved, but the ease of removal for maintenance deteriorates
Solution Approach 1:
The coupling between the drive roller and drive means is divided into two separate coupling members: a first coupling member on the drive roller shaft and a second coupling member on the drive means. These members can be easily engaged and disengaged, allowing the drive roller to be firmly connected for reliable power transmission during operation, yet easily separated for maintenance without complicated disassembly procedures.
2Stability of the object's composition
If the support structure is permanently fixed to maintain stable support, then the stability of support is improved, but the ease of replacement deteriorates
Solution Approach 1:
The support means is designed with dynamic attachment capability, allowing it to be detachably connected to the support structure during operation for stable support, yet easily removed when replacement is needed. This dynamic connection enables the support means to transition between a fixed stable state during operation and a removable state for maintenance or replacement.
3Ease of operation
If a quick release mechanism is implemented for easy removal, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The quick release functionality is achieved by extracting the essential coupling function into separate, simple coupling members that can be easily engaged and disengaged. Rather than implementing a complex integrated quick-release mechanism, the invention uses simple protrusion-recess coupling members that provide quick release capability while maintaining minimal structural complexity.

AI summary
The invention relates to a drive roller assembly for a conveyor system, the drive roller assembly comprising: a drive roller having a longitudinal axis, the drive roller comprising a roller body and a shaft, the shaft having first and second axial end portions, the drive roller being rotatable around the longitudinal axis, a support structure for rotatably supporting the drive roller, the support structure comprising support means for rotatably supporting the second axial end portion of the shaft and drive means for rotatably driving said drive roller. According to the invention, the drive roller assembly further comprises: coupling means for rotatably coupling said first axial end portion of the shaft and said drive means in an axially engaged condition of said coupling means in which the drive roller is in rotatable engagement with said drive means and for axially releasing the engagement of said first axial end portion of the shaft and the drive means in an axially disengaged condition of said coupling means, wherein the support means is adapted to be detachably attached to an attachment portion of said support structure to maintain said drive roller rotatably supported on said support structure when attached and to allow said drive roller to be removed from said support structure when detached.
