Double-roll machine slip-on gear alignment table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and disassembly of roller presses are cumbersome and risky due to the need for precise alignment of slip-on gears, which can lead to damage during the hydraulic actuation of the shrink disk connection if not properly aligned, especially when the suspension point is not at the center of gravity.
Innovation Solution
A machine table with vertically and horizontally adjustable supports and hydraulic cylinders is used to align and stabilize the slip-on gears during assembly and disassembly, ensuring precise alignment and simplifying the roll change process by allowing symmetrical force application during gear removal and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If slip-on gears are assembled and disassembled using cable cranes with hydraulic actuation, then the connection can transmit very high torque, but the risk of damage increases due to difficult alignment when the suspension point is not at the center of gravity
Solution Approach 1:
A support table is introduced as an intermediary device between the slip-on gear and the cable crane. The support table provides a stable, level surface that facilitates precise alignment of the gear shaft with the drive journal during assembly and disassembly, eliminating the alignment difficulties caused by suspending the gear from a cable crane with the suspension point away from the center of gravity
Solution Approach 2:
The invention replaces the cable crane suspension system with a support table-based mechanical system. Instead of suspending the slip-on gear from a cable crane (which creates alignment problems), the gear is supported on a level table surface, allowing for easier and more accurate alignment during the assembly and disassembly processes
2Ease of operation
If slip-on gears are supported on cable cranes during assembly and disassembly, then the gear can be positioned, but the alignment process becomes difficult and time-consuming
Solution Approach 1:
The support table is prepared in advance with the appropriate level and positioning features before the assembly or disassembly operation begins. This preliminary preparation eliminates the need for time-consuming alignment adjustments during the actual assembly or disassembly process, as the gear can be directly positioned on the pre-prepared table surface
Solution Approach 2:
The support table serves as a mediator between the slip-on gear and the work environment, providing a stable, level reference surface that simplifies alignment. This intermediary device eliminates the complexity of aligning a suspended gear from a cable crane, making the entire assembly and disassembly process faster and easier
3Productivity
If precise alignment is not achieved during assembly and disassembly, then the process can be completed quickly, but damage occurs to the drive journals and hollow gear shafts
Solution Approach 1:
The support table provides a cushioning effect by distributing the weight and alignment forces evenly across the gear and table surface. This prevents concentrated forces that could cause damage to the drive journals or hollow gear shafts, while still allowing for quick assembly and disassembly operations
Solution Approach 2:
The support table acts as a protective intermediary between the assembly/disassembly operation and the critical components (drive journals and hollow gear shafts). By providing a stable, level surface, it ensures that alignment forces are applied correctly, preventing damage to these sensitive components while maintaining operational efficiency

Function Achieved in This Case
This solution facilitates easier, faster, and safer assembly and disassembly of roller presses by ensuring accurate alignment of the shrink disk connection, reducing the risk of damage and streamlining the roll change process.
Implementation Method 1
three vertically and horizontally adjustable supports arranged in a triangle, on which the respective slip-on gear is mounted during assembly and disassembly
Implementation Method 2
the foot part of which can be used for horizontal alignment on the tabletop, e.g. B. can be connected to a simple screw drive
Implementation Method 3
a hydraulic cylinder arranged parallel to it between the machine frame and the slip-on gear can be arranged on both sides of the drive pin in such a way that the force required to pull off/slide on the gear is symmetrical

AI summary
The aim of the invention is to design a double-roll machine, especially a rolling press for comminuting a bed of granular material, in such a way that the rolls can be mounted and dismounted and thus replaced more easily, faster, and more safely, said double-roll machine comprising two rotatably mounted, counterrotatingly driven rolls which are separated from each other by a nip and on the drive journals of which slip-on gear mechanisms are mounted as planetary reduction gears. Said aim is achieved by disposing a supporting table (19) underneath the slip-on gear mechanisms (15, 16), said supporting table (19) encompassing one respective table top (21, 22) which can be moved fore and aft parallel to the roll shaft in at least one direction, and positioning three vertically and horizontally adjustable bearing supports (23, 24, 25), which are mounted in a triangular arrangement, on the table top. The respective slip-on gear mechanism (15, 16) can be mounted on the bearing supports (23, 24, 25) so as to be aligned in a flush, offset-free manner relative to the drive journal of the roll shaft when the slip-on gear mechanism (15, 16) is mounted and dismounted.
