Pivotally Movable Motor Support for Belt Tension Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement mechanisms using endless belts between driving and driven pulleys in printing apparatuses require operators to relax and re-adjust tension when replacing motors, posing a significant burden due to the complexity of tension management.
Innovation Solution
A movement mechanism where the supporting member for the motor is pivotally movable, allowing the distance between the driving and driven pulleys to shorten, enabling motor replacement without relaxing or re-adjusting the belt tension, facilitated by abutting and abutted portions acting as pivotal axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the motor is replaced in the conventional movement mechanism, then the motor can be updated or maintained, but the belt tension must be relaxed and re-adjusted using a belt tensiometer, increasing operational complexity and time
Solution Approach 1:
The supporting member is designed to be pivotally movable about a position serving as a pivotal axis, allowing the distance between the driving pulley and the driven pulley to shorten. This dynamic adjustment mechanism enables the endless belt to be easily removed and re-stretched without requiring tension relaxation or re-adjustment using a belt tensiometer, thereby simplifying motor replacement operations
Solution Approach 2:
The movement mechanism is divided into separable components: the motor mounted on the pivotally movable supporting member can be independently removed from the base body portion, while the endless belt remains stretched between the driving and driven pulleys. This segmentation allows motor replacement without disturbing the belt tension system
2Ease of repair
If the motor is replaced with a fixed supporting member, then the structure is simple and stable, but the motor cannot be replaced without relaxing and re-adjusting the belt tension
Solution Approach 1:
The supporting member is designed to be pivotally movable about a position serving as a pivotal axis, allowing the distance between the driving pulley and the driven pulley to shorten. This dynamic adjustment mechanism enables the endless belt to be easily removed and re-stretched without requiring tension relaxation or re-adjustment using a belt tensiometer, thereby simplifying motor replacement operations
Solution Approach 2:
The supporting member serves multiple functions: it supports the motor, provides a pivotal axis for movement, and enables the distance between pulleys to be adjusted. This multi-functionality reduces the need for additional components that would otherwise be required to achieve motor replacement capability

AI summary
A movement mechanism for a movable body including a motor including a rotation shaft, a supporting member that supports the motor, an attachment member fixed to a base body portion and to which the supporting member is attached, a driving pulley coupled to the rotation shaft, a driven pulley attached to the base body portion, an endless belt stretched between the driving pulley and the driven pulley, and the movable body attached to the endless belt, in which the supporting member is configured to be pivotally movable about a position serving as a pivotal axis such that a distance between the driving pulley and the driven pulley shortens, the position being at a side of the driven pulley from the driving pulley in a stretching direction in which the endless belt is stretched between the driving pulley and the driven pulley.
