Loom Driving Shaft Gear Train for Easier Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loom designs require complex operations for maintenance due to the need to release and reconnect the driving shaft and driving-force transmission mechanism, particularly when using pulleys and timing belts, complicating maintenance procedures.
Innovation Solution
The loom incorporates a driving-force transmission mechanism with a driving-force transmission shaft that protrudes from the side frame and is connected to the driving motor via a gear train, allowing the frame cover to be removed without disconnecting the driving shaft and transmission mechanism, and includes a separate space for the gear train within a driving box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving shaft and driving-force transmission mechanism are connected via pulleys and timing belts protruding from the side frame, then the transmission function is achieved, but maintenance operations become complicated requiring release and reconnection of the transmission mechanism
Solution Approach 1:
The invention divides the transmission system into two independent segments: the driving-force transmission mechanism (motor and pulleys) remains connected and housed in the driving box, while the frame cover can be independently removed for maintenance. This segmentation allows maintenance access without disrupting the transmission connection.
Solution Approach 2:
The invention extracts the driving-force transmission mechanism into a separate driving box that is independent from the frame cover assembly. This extraction allows the frame cover to be removed for maintenance while the transmission mechanism remains intact and connected within its own housing.
2Reliability
If the driving shaft protrudes from the side frame for connection with the driving-force transmission mechanism, then the transmission connection is achieved, but the frame cover must be opened for maintenance complicating the procedure
Solution Approach 1:
The invention segments the overall structure into a driving box containing the transmission mechanism and a frame assembly with removable cover. This segmentation allows the frame cover to be accessed independently without requiring disconnection of the transmission components.
Solution Approach 2:
The driving-force transmission mechanism is extracted into a separate driving box that houses all transmission components (motor, pulleys, timing belts). This extraction eliminates the need to open the frame cover for transmission maintenance, simplifying the overall maintenance procedure.
3Adaptability or versatility
If pulleys and timing belts are used for connecting the driving motor and driving shaft, then the transmission flexibility is achieved, but tension adjustment is required increasing operational complexity
Solution Approach 1:
The timing belt tensioning mechanism is designed to be self-adjusting within the driving box, eliminating the need for manual tension adjustment operations. The system maintains optimal tension automatically through its internal mechanism.

AI summary
A driving-force transmission mechanism (80) includes a driving-force transmission shaft (82) that is provided so as to protrude from a side wall (12b) of a side frame (12) while extending parallel to a driving shaft (30) within a space of the side frame (12) and connected to a driving motor (20), and a gear train (84) that connects the driving-force transmission shaft (82) and a driving shaft (30).
