Disintegrating Machine Bearing Mount Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shredding machines with multiple cutter shafts face high maintenance costs due to the time and effort required to replace blade shafts, necessitating an improvement in maintenance ease.
Innovation Solution
The shredding machine incorporates a bearing mount system with a pivoting bridge and bearing plates that allow quick removal and reinstallation of cutter shafts, featuring a multifunctional bearing plate for crane hook connection, storage, and bearing support, reducing the need for separate fastening and enabling backlash-free mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If traditional bearing mounts are used for cutter shafts, then the structure is simple, but the maintenance time and labor are excessive
Solution Approach 1:
The bearing mount is divided into a base body and a bridge that can pivot relative to each other. The bridge can be opened independently to provide access to cutter shafts, allowing maintenance personnel to remove and replace cutter shafts quickly without disassembling the entire bearing mount structure.
Solution Approach 2:
The bridge is designed to pivot between a closed position (during operation) and an open position (during maintenance). This dynamic structure allows the bearing mount to transition from a enclosed protective structure to an open access structure, significantly reducing maintenance time while maintaining structural integrity during operation.
2Ease of repair
If cutter shafts are equipped with multifunctional bearing plates, then the ease of maintenance improves, but the device complexity increases
Solution Approach 1:
The bearing plate is designed with multiple functions: it provides bearing support for the cutter shaft, serves as a lifting attachment point for cranes, and acts as a support base when the cutter shaft is removed. By integrating these functions into a single component, the patent reduces the number of separate parts needed, simplifying the overall device while improving maintenance ease.
3Ease of operation
If the bridge is designed to pivot open for maintenance access, then the ease of operation improves, but the structural complexity increases
Solution Approach 1:
The bridge is integrated with the base body of the bearing mount, forming a unified structure where the bridge pivots relative to the base body. This merging of components allows the maintenance access function to be achieved without adding completely separate mechanisms, thereby limiting the increase in structural complexity.
