Roller Brush Mounting Assembly with Resilient Idle Shaft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing and removing roller brushes from cleaning apparatuses are time-consuming and require multiple personnel, involving complex disassembly of machine panels and fasteners.
Innovation Solution
A mounting assembly with a longitudinal blind bore in the roller brush end structure and a loader assembly that applies a resilient load to an idle shaft to facilitate easy engagement and disengagement of the brush with the drive mechanism, allowing for single-person installation and removal without disassembling the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting methods are used, then the roller brush can be securely mounted, but the installation and removal process requires multiple personnel and is time-consuming
Solution Approach 1:
The mounting assembly is divided into separate functional components: a mounting housing with an idle shaft, and a loader assembly with a lever arm. This segmentation allows the operator to independently manipulate the loading mechanism without needing to disassemble the entire mounting structure or require multiple personnel for coordination.
Solution Approach 2:
The idle shaft is designed with dynamic movement capability, allowing it to extend and retract relative to the mounting housing. When the loader assembly applies load, the idle shaft automatically retracts to enable brush removal. This dynamic adjustment eliminates the need for static disassembly operations and reduces installation time.
2Reliability
If traditional mounting methods are used, then the roller brush can be securely mounted, but the process involves complex disassembly of machine panels and fasteners
Solution Approach 1:
The loading function is extracted as a separate loader assembly that can be independently operated. This allows the mounting security to be maintained through the idle shaft engagement while the loading/unloading operation is simplified to lever manipulation, eliminating the need to disassemble machine panels and fasteners.
Solution Approach 2:
The idle shaft serves as an intermediary element between the mounting housing and the roller brush. It provides a mechanical interface that secures the brush during operation while allowing controlled movement during loading and unloading, thus maintaining reliability while reducing procedural complexity.
3Ease of operation
If the idle shaft is fixed in position, then the mounting structure is simpler, but the roller brush cannot be easily removed without disassembly
Solution Approach 1:
The idle shaft is designed with dynamic movement capability, allowing it to extend and retract relative to the mounting housing. When the loader assembly applies load, the idle shaft automatically retracts to enable brush removal. This dynamic adjustment eliminates the need for static disassembly operations.
Solution Approach 2:
The mounting assembly performs its own loading and unloading function through the integrated loader assembly. The system uses its own components (lever arm, spring, idle shaft) to facilitate brush removal without requiring external tools or additional disassembly steps, making the complex mechanism self-sufficient.

AI summary
A mounting assembly 10 for mounting a roller brush 12 onto an operating apparatus includes a mounting structure 14 configured to be mountable on the operating apparatus. The mounting structure has a through hole for receiving an idle shaft 16 that is sized to be engageable within a blind hole 42 formed in the adjacent end hub 32 of the brush 12. The idle shaft 16 is resiliently loaded in the direction toward the brush hub 12 by a loader assembly 18 which includes a compression spring 16 acting against retaining ring 48 engaged with the idle shaft 16.
